Description

Manufacture method of building interior materials and building interior materials {METHOD FOR MANUFACTURING BUILDING INTERIOR MATERIAL AND BUILDING INTERIOR MATERIAL}

The present invention relates to a method for manufacturing building interior materials and building interior materials. More specifically, the present invention relates to a method for manufacturing a building interior material and a building interior material in which a natural embossing surface is formed using a gypsum mixture in which gypsum, vermiculite and functional minerals are mixed.

As eco-friendliness is one of the most important issues in building interior materials, the market and demand are rapidly shifting to environmentally friendly interior materials. In response to the demand for eco-friendly building interior materials, various building interior materials have been commercialized by molding and molding gypsum, vermiculite, and minerals such as gelite and loess.

Existing building interior products are not satisfactory in terms of strength, embossing, surface texture, gloss, and naturalness. Looking at the conventional products produced in the past, the product is low in strength and lacks similarity with natural stone, which is a characteristic of the product. There seems to be a clear feeling.

Most of the existing products in Korea seem to be fragile and the surface of the product does not appear natural, so it seems to be easily contaminated and seems to be made artificially. The reason is that when gypsum, vermiculite, and a small amount of gelite gypsum mixture and water are agitated and injected into the mold, the heavy gypsum falls below and the lightweight foamed vermiculite, which is about 1 / 20th of the gypsum mass, is light in mass. This is because the surface of the product is concealed by natural plaster (embo) and natural color, which is the advantage of vermiculite, by heavy plaster. As a result, existing products have a monotonous appearance and result in gypsum dust.

Republic of Korea Patent Publication No. 10-2013-0030090 (Published March 26, 2013) Republic of Korea Patent Publication No. 10-2012-0025789 (published March 16, 2012) Korean Patent Registration Publication No. 10-0833898 (June 2, 2008) Republic of Korea Patent Publication No. 10-2007-0022410 (published February 27, 2007) Republic of Korea Patent Publication No. 10-2006-0057567 (published May 26, 2006) Republic of Korea Patent Publication No. 10-2005-0090257 (Published September 13, 2005)

As a result, building interior materials using gypsum, vermiculite, and functional minerals should be as strong as natural stones and produce a smooth, smooth surface that looks rough due to luxurious colors and natural bubbles (embossing) for natural texture of the surface. In addition, it should be useful for environment-friendly and interior by exerting various functionalities contained in materials to protect health. To meet these needs, products need to be developed by upgrading the quality of existing products to the limit.

In addition, in one example, the functional mineral powder may be a gellite powder, a pearlite powder or a mixed powder thereof.

In another example, in the first stirring step, a retardant may be added to the first stirring so that the weight ratio of the gypsum powder and the retardant is 100: 1 to 5.

Further, according to one example, in the injecting and compressing step, fresh water may be evenly sprayed onto the bottom of the prepared mold and the first stirred mixture may be injected.

In the case of molding a building interior material by injecting a gypsum mixture, which is a mixture of gypsum, vermiculite, and functional minerals with water, into a mold, the carved pattern (unevenness) is sufficiently displayed on the bottom surface of the mold, which is the surface layer of the final product. In order to increase the mixing ratio of water to the gypsum to increase the flow rate of the dough is made into the mold. In this case, since the mass of gypsum is about 20 times larger than vermiculite, the surface layer of the final product can be sufficiently patterned, but because the gypsum sinks in the mold, the surface layer of the final product is covered with gypsum. Its weakness is likely to break and it is not natural at all.

Accordingly, while making the product high strength, it is necessary to form natural embossing on the surface of the product to give a feeling like natural stone. Furthermore, on the one hand, it may be necessary to have the smoothness and subtle glow due to the softness and semi-glow of the surface of the product, or further, to express the high-quality colors such as monochromatic to multicolor mixtures.

In the present invention, in order to solve this problem, to control the mixing ratio of the gypsum mixture and water, and to solve through the settling of particles through compression during the injection of the mold, and to express the color through the stirring of water containing (Press) pigment .

[Building Interior Material Manufacturing Method]

First, the building interior manufacturing method according to one aspect of the present invention will be described with reference to the drawings. At this time, not only the manufacturing method shown in FIGS. 1 to 5 but also the drawings of the building interior material shown in FIG.

1 is a flowchart showing a method for manufacturing a building interior material according to an embodiment of the present invention, FIG. 2 is a flowchart showing a method for manufacturing a building interior material according to another embodiment of the present invention, and FIG. 4 is a flowchart illustrating a method of manufacturing building interior materials according to an embodiment, and FIG. 4 is a flowchart illustrating a method of manufacturing building interior materials according to another embodiment of the present invention, and FIG. 5 is another embodiment of the present invention. The entire flow chart illustrating a method for manufacturing the building interior according to.

6 is a cross-sectional view schematically showing a cross section of the building interior material according to an embodiment of the present invention.

1 to 5, the building interior manufacturing method according to one example is the first stirring step (S100, S1100, S2100, S3100), injection and compression step (S200, S1200, S3200), reinforcing step (S300), Second stirring step 4300, residual molding step (S500), and demolding and drying step (S600). Referring to FIG. 5, the building interior manufacturing method according to an example may further include a surface treatment step S700.

First, in the first stirring step (S100, S1100, S2100, S3100), the gypsum powder 70 ~ 80wt%, vermiculite powder 10 ~ 25wt% and functional mineral powder 5 ~ 10wt% ratio of the first gypsum mixture and the first stirring The water is first stirred at a volume ratio ranging from 4: 1 to 7: 3. In the injection and compression step (S200, S1200, S3200), the first stirred mixture stirred in the first stirring step (S100, S1100, S2100, S3100) is injected into the prepared mold by a portion and compressed to granulate the particles in the first stirred mixture. Is settled to the bottom surface to form an embossed surface. In the reinforcing step (S300), the strength reinforcing material is placed on top of the first stirring mixture injected into the mold. For example, the reinforcement step S300 may be performed after compression in the injection and compression steps S200, S1200, and S3200, or may be performed before compression after injection. In the second stirring step (S400), the second gypsum mixture and the second stirring water, which are mixed at a ratio of 80 to 90 wt% of gypsum powder and 10 to 20 wt% of vermiculite powder, are prepared in a volume ratio of 7: 3 to 3: 2. The second stirring is more dilute than the stirring mixture. In the remaining molding step (S500), the second stirring mixture stirred in the second stirring step (S400) is injected into the upper part of the strength reinforcing material of the mold to fill and pre-dry the remaining portion of the mold. In the demolding and drying step (S600), the mold is demolded in a semi-dry state and dried in a drying furnace.

Hereinafter, referring to Figures 1 to 5, the first stirring step (S100, S1100, S2100, S3100), injection and compression step (S200, S1200, S3200), reinforcing step (S300), the second stirring step (4300) It looks at in detail in the order of the remaining molding step (S500), demolding and drying step (S600), and the surface treatment step (S700).

First stirring step (S100, S1100, S2100, S3100)

With reference to Figures 1 to 5 looks at the first stirring step (S100, S1100, S2100, S3100). In the first stirring step (S100, S1100, S2100, S3100), the first gypsum mixture and the first stirring water in which the gypsum powder, vermiculite powder and functional mineral powder are mixed are first stirred. At this time, the first gypsum mixture is mixed in the proportion of gypsum powder 70 ~ 80wt%, vermiculite powder 10 ~ 25wt% and functional mineral powder 5 ~ 10wt%. Gypsum powder is coagulated because it hardens by hydration when mixed with water. When the gypsum powder is higher than 80wt%, the content of vermiculite powder and / or functional mineral powder is reduced, making it difficult to fully exhibit the excellent properties of vermiculite powder and functional minerals, and the content of gypsum powder that acts as a coagulant by hydration reaction. Lowering below 70wt% can make it difficult to achieve the strength of building interior products. Accordingly, the content of gypsum powder is 70 to 80wt% and the content of the remaining vermiculite powder and functional powder is 20 to 30wt%.

Vermiculite is porous and has good absorption ability and is widely used as a heat-resistant material and a soundproofing material. In addition, vermiculite expands when heated. Accordingly, when the vermiculite is heated and expanded, it is possible to obtain a lighter and more porous material. Vermiculite powder can be obtained by heating and expanding the vermiculite to prepare a powder, and thus the vermiculite powder has excellent thermal insulation, soundproofing, and moisture proof properties due to the continuous hollow layer caused by bubbles. For example, in the examples of the present invention, expanded vermiculite powder having a light insulating property by powdering expanded vermiculite is used. By using a mixture of expanded vermiculite powder with lightweight insulation, it is possible to implement a lightweight insulation interior material.

The functional mineral powder is a powder of a functional mineral, and may be, for example, a powder of a mineral having any one or more functions such as antibacterial, far infrared, anion, moisture proof, heat insulation, sound insulation, purification, and adsorption. Examples of the functional minerals include germanium-containing minerals, pearlite minerals, illite minerals, zeolite minerals, and the like, but are not limited thereto.

For example, in one example, the functional mineral powder may be a gellite powder, a pearlite powder or a mixed powder thereof. Gellite is one example of a germanium containing mineral. The pearlite powder is light and has excellent porosity, and like the vermiculite, has excellent thermal insulation, soundproofing and moisture proofing properties.

In one example, the average particle size of vermiculite powder in the first gypsum mixture mixed in the first stirring step (S100, S1100, S2100, S3100) is greater than the average particle size of the gypsum powder and the functional mineral powder. For example, the vermiculite powder may be about 1 to 3 mm, the gypsum powder may be 1 mm or less, and the functional mineral powder may be 1 mm or less. Accordingly, the particle size of the first stirring mixture in which the first gypsum mixture and the first stirring water are stirred can be maintained at about 1 to 4 mm.

Referring back to Figures 1 to 5, in the first stirring step (S100, S1100, S2100, S3100), the first gypsum mixture and the first water for stirring the first stirring at a volume ratio ranging from 4: 1 to 7: 3 do. First stirring results in a highly viscous first stirring mixture. In this case, the higher the content of the gypsum powder in the first gypsum mixture, the higher the stirring ratio of the water for the first stirring, and the lower the content of the gypsum powder, the lower the stirring ratio of the first stirring water. For example, when the mixing ratio of the first gypsum mixture and the first stirring water becomes high in a state where the content of the gypsum powder is low, the stirring becomes thin and thus it becomes difficult to form embossing by the particles of the first stirring mixture on the final product surface. It may be difficult to maintain sufficient strength of the final product. On the other hand, if the stirring ratio of the first gypsum mixture and the first stirring water is low in the state of high gypsum powder content, the stirring rate is too hard to rapidly cure, which may make it difficult to control the process in the manufacturing process and further, the embossing of the final product. The surface may not be smooth and rough.

In general, the existing agitation method is to increase the mixing ratio (mixing ratio of water to the gypsum) to make the dough to flow enough to be injected into the mold. Conventionally, the coma was increased to sufficiently display the carved patterns (unevenness) on the bottom surface of the mold, which is the surface layer of the final product. In this case, since the mass of gypsum is about 20 times larger than vermiculite, the surface layer of the final product can be sufficiently patterned, but since the gypsum sinks in the mold and vermiculite, which has a small specific gravity and a large particle size, comes to the surface of the final product. Because it is covered with a natural stone, it does not feel like a natural stone, its strength is weak, and is likely to be broken.

As a means for solving this problem, by maintaining the stirring ratio of the first gypsum mixture and the first stirring water properly, the first gypsum mixture and the first stirring water when the first gypsum mixture and the first stirring water are stirred. To a volume ratio in the range of 4: 1 to 7: 3 to lower the coma ratio than the conventional method to increase the high strength of the gypsum, and as another problem solving means by applying pressure as described below to the particles of the first stirring mixture, For example, embossing is formed on the surface of the vermiculite powder, which has a large average particle size, to contact the bottom of the mold to give a natural stone-like feel. In the case of this method, since the mixing ratio is lower than the conventional one, the whole dough is not soft, and only the partially agglomerated portion is continuously stirred by hand or using a mixer. It is made of particles about 1 ~ 4mm small like rice grains. At this time, the spray may be used while mixing the first stirring water.

Injecting and compressing the first stirring mixture to be obtained through the stirring process described later (S200, S1200, S3200) after injection into the mold to form the surface of the final product through compression through a roller press, vertical press, manual roller, etc. Natural embossing irregularities can be implemented in the mold bottom and the contact surface portion, and in the injection and compression step (S1200, S3200), evenly sprayed with water in advance on the mold bottom surface, and then injected and compressed by injecting the first stirring mixture into the contact surface with the mold bottom. It is possible to realize a smooth surface like marble on the surface.

On the other hand, in the first stirring step (S100, S1100, S2100, S3100) it should be noted that the curing is fast because of low coma ratio. Depending on the curing rate, a retardant or the like can be used. On the other hand, the strength is strong because the coma is low. For example, referring to FIG. 2, in one example, the first stirring may be performed by adding a retarder such that the weight ratio of the gypsum powder and the retardant is 100: 1 to 5 in the first stirring step (S1100). If you want to slow down or control the rate of hardening or setting of gypsum, you can adjust the retardant. By adding an appropriate amount of retarder, curing of the gypsum to coagulation may be delayed to overcome the problem of coagulation in the stirring process, and may be naturally molded through the injection and compression steps (S200, S1200, S3200) described below. For example, when 30 g of water is stirred in 100 g of gypsum, the curing or condensation rate of gypsum may be slowed down by about 25 minutes when 2.5g is added and about 40 minutes when 5g is added. Agitation can be performed. The control of the curing to setting rate by the retardant depends not only on the addition amount of the retardant, but also on the gypsum content of the first gypsum mixture, the mixing ratio of water in the first stirring mixture, and the like, and thus should be appropriately adjusted according to the embodiment. In the first stirring step (S1100) illustrated in FIG. 2, the configuration of first stirring by adding a retarder is not shown, but may also be applied to the embodiments according to FIGS. 3 to 5.

Next, referring to Figures 3 to 4, looks at the first stirring step (S2100, S3100). FIG. 3 illustrates a process for coloring the top layer of the final product (see 100 in FIG. 6) in a single color, and FIG. 4 illustrates a process for allowing the top layer 100 of the final product to be mixed and colored in multiple colors. .

3 and / or 4, in one example, the first stirring water in the first stirring step (S2100, S3100) is colored water. The first stirring water to be used for stirring with the first gypsum mixture is prepared by coloring the desired color. 3 and / or 4, the injection and compression step (S1200, S3200) described below, which will be described below the first stirring mixture consisting of agitated grains of grain size of about 1 ~ 4mm and colored grains by stirring with the colored first stirring water as shown in FIG. ), Evenly injected into the mold and compressed, the colored granules appear in the surface layer naturally in the final layer. 3 and / or 4, dyeing is performed in the stirring process as shown in FIG. 3 and / or 4, and otherwise, although not shown, irrespective of stirring, the water containing the pigment is sprayed with a spray or the like and the first stirring mixture is injected. Dyeing with a different feeling can also be realized by the post dye method.

Furthermore, an example will be described with reference to FIG. 4. At this time, the first gypsum mixture is divided into a plurality according to the setting in the first stirring step (S3100) and the first stirring water is colored and divided into a plurality of colors to correspond to the ratio of the first divided gypsum mixture. It can be prepared and stirred for each color. Thereafter, in order to form a multicolored product, a plurality of first stirring mixtures for each color stirred in the injection and compression step S3200 described below may be mixed and injected into a mold. When a variety of mixing colors are desired, the first stirring water used for the first stirring is prepared with a plurality of stirring dye water containing various pigments, respectively, and the first gypsum mixtures distributed corresponding to the distribution ratio of the water, respectively. By first stirring and randomly mixing the mold injection process described below or during the mold injection process to be described later, natural artificial colors may be realized, or the color may be arranged at regular intervals. Through this, it is possible to realize the surface like natural marble, and after the injection and compression step (S3200), embossing is live on the surface of the product through the press, etc. It can manufacture. The result of this manufacturing method can feel a huge difference from those by the conventional method.

Injection and Compression Steps (S200, S1200, S3200)

With reference to Figures 1 to 5 looks at the injection and compression step (S200, S1200, S3200). In the injection and compression step (S200, S1200, S3200), the first stirred mixture stirred in the first stirring step (S100, S1100, S2100, S3100) is injected into the prepared mold and compressed into a portion of the first stirred mixture. The particles are settled to the bottom surface to form an embossed surface. For example, a viscous first stirred mixture in which the first gypsum mixture and the first stirring water are stirred is injected into the mold less than half or two thirds, and then pressurized by a press or the like to obtain approximately half the height of the mold. 1 Make a stirred mixed layer. Since the first stirring mixed layer has a low mixing ratio and high viscosity, the first stirring mixed layer is not densely filled to the bottom of the mold. However, by applying pressure with a press or the like, the particles of the first stirring mixture settle to the bottom of the mold and the bottom surface of the mold. The embossed structure can be formed at the contact surface portion in contact with the first surface, and the first stirred mixed layer formed up to about half the height of the mold becomes the upper layer 100 in the final product after curing. In order to apply pressure, a roller press, a vertical press, a hot roller press, a manual roller, or the like may be used, but is not limited thereto. At this time, the strength of the upper layer 100 of the final product is increased due to the compression.

At this time, by appropriately adjusting the compressive strength, bubbles (embossing) naturally appear on the surface of the contact surface area with the mold bottom, and as described below, when fresh water is evenly sprayed on the mold bottom surface, it is pressed according to the pressure and contacted with water on the contact surface. Similar to marble, the texture of the surface can be expressed smoothly. For example, when a first stirred mixture having small particles, such as millet to rice grains of about 1 to 4 mm, is first injected into the mold and forcedly compressed by a roller or a press, the small grains such as rice grains dried according to the compressive strength are pressed. Particles, for example, agitated particles of vermiculite powder having a large average particle size appear pressed at the bottom of the surface layer so that the kernels are alive and natural embossing can be seen.

For example, in one example, when the vermiculite powder has the largest average particle size in the first gypsum mixture, the stirring particles of the vermiculite powder in the first stirred mixture are bottomed by compression in the injection and compression steps (S200, S1200, S3200). It can settle to face to form an embossed surface. If the first stirring mixture is left in the mold, the surface layer of the final product may be rough due to the viscosity of the first stirring mixture, and the surface area in contact with the bottom of the mold because the mass of gypsum is about 20 times larger than vermiculite. Is mostly covered by gypsum hydrate, but by forcibly compressing as in this step, stirring particles of vermiculite powder with a large average particle size sink to the bottom to form an embossed surface and at the same time interact with water pre-spread on the mold bottom On the mold bottom surface and the contact surface, a smooth surface can be realized.

For example, when the particles of the stirred first stirring mixture are about 1 to 4 mm, the compressed thickness after injection of the mold in the injection and compression steps S200, S1200 and S3200 may be about 4 to 6 mm. Accordingly, the thickness of the final product can be manufactured about 8 ~ 12mm.

In addition, one example will be described with reference to FIGS. 2 to 5. At this time, in the injection and compression step (S1200, S3200), it is possible to evenly spray fresh water (spray) to the bottom of the prepared mold and inject the first stirring mixture. Before injecting the stirred first stirred mixture into the mold, spray the pure water evenly over the prepared mold floor, and inject and compress the first stirred mixture to make the water and the first stirred mixture compatible. S600), the contact surface in contact with the bottom surface of the mold, that is, the surface of the final product is semi-finished, soft luster and has a texture similar to natural stone marble.

In particular, referring to FIGS. 3 to 4, since the first stirring mixture is colored in a single color to a multicolor, before pouring the stirred first stirring mixture into the mold, the first mold mixture is poured after clean water is sprayed onto the prepared mold bottom. When compressed and dried, the contact surface in contact with the bottom of the mold may be semi-finished, glossy, tinted, and have a texture similar to that of natural stone marble. 3 to 4 in the injection and compression step (S1200, S3200) described below the first stirring mixture consisting of agitated particles of the grain size of about 1 ~ 4mm and colored for example by stirring with colored first stirring water as shown in FIG. Evenly injected into the mold, compressed and dried, the colored particles appear in the surface layer naturally in a circular form. At this time, the mixed stone solids colored in monochromatic or multicolored due to compression have a natural color and do not discolor even after construction of the final product.

Unlike the existing method in this manufacturing process, it is a new mechanism with a subtle color like marble, and it is similar to natural stone due to its strong, smooth and uneven embossing. A product can be prepared.

Although not shown, in one example, the dye solution is sprayed on the bottom of the prepared mold for coloring the product in the injection and compression step (S200, S1200), without performing the preliminary process in the first stirring step (S100, S1100) It may be sprinkled on the back and inject the first stirred mixture. That is, in the injection and compression step (S200, S1200) without the preliminary process in the first stirring step (S2100, S3100) in Figures 3 to 4 before spraying the water containing the pigment in the mold before the first stirring mixture injection, Dyeing with different sensations can also be achieved by the post dye method of injecting the first stirred mixture.

Residual Molding Step (S500)

Next, the residual molding step S500 will be described with reference to FIGS. 1 to 5. In the remaining molding step (S500), the second stirring mixture stirred in the second stirring step (S400) is injected into the upper part of the strength reinforcing material of the mold to fill and pre-dry the remaining portion of the mold.

In this case, the remaining part may be filled in the remaining molding step S500 and the upper surface may be arranged horizontally. For example, a second stirring mixture is injected into the other half of the mold and the surface is leveled and smoothly finished using a tool such as the like to make an attaching surface to be attached to a wall of a building or the like.

For example, the semi-drying time may be performed while drying at room temperature for about 5 to 10 minutes, and may be adjusted according to the embodiment.

Demoulding and Drying Steps (S600)

Next, referring to FIGS. 1 to 5, the demolding and drying step (S600) will be described. In the demolding and drying step (S600), the mold is demolded in a semi-dry state and dried in a drying furnace.

For example, the drying furnace may be dried in a range of about 30 to 90 minutes at a temperature of about 80 to 100 degrees, and the drying temperature and drying time may be appropriately adjusted according to the embodiment.

Surface treatment step (S700)

In addition, one example will be described with reference to FIG. 5. At this time, the building interior material manufacturing method may further include a surface treatment step (S700). In the surface treatment step S700, a pattern is formed on the surface of the demolded or dried product in a demolding and drying step S600 by a marbling method or a digital printing method or an image is formed by a digital printing method.
