Description

[Detailed description of the invention]

0001

[Field of Industrial Application] This invention relates to a synthetic resin architectural decorative material, and more particularly to a synthetic resin architectural decorative material formed on the surface of architectural members such as handrail cap covers. be.

0002

2. Description of the Related Art Generally, in handrails installed on stairs or walls, the surface of a metal base is covered with a decorative material such as a synthetic resin kasagi cover to enhance visual beauty.

[0003] Conventionally, this type of decorative material is generally known to be made by extrusion molding a soft (semi-hard) vinyl chloride resin to which a coloring pigment is added. In addition, the surface may be embossed, or a transparent layer may be integrally formed on the surface of the base material during molding to achieve a uniform surface finish, or metallic pigment may be added to eliminate a monotonous color tone. Additives are also used.

0004

[Problems to be Solved by the Invention] However, in conventional products to which colored pigments are added, the feel of the synthetic resin itself, the so-called plastic feel, is emphasized, and the properties of other constituent members and surrounding members, that is, metal materials, are emphasized. There was a sense of incongruity between the metallic feel and the natural feel of the wood, making it difficult to achieve harmony. Furthermore, if the surface is embossed or the surface layer is uniformly finished, the effect of removing the dice mark can be obtained, but the color tone cannot be changed. In addition, in the case of products with metallic pigments added, it is possible to give a metallic feel to the surface and eliminate the sense of incongruity with other metal parts to some extent, but in conventional metallic decorative materials, the particle size is generally not visible to the naked eye. Since the amount of fine-sized (specifically 50 μm or less) metallic pigment added is 1.5 to 2.0 parts by weight, the color of the metallic pigment appears excessively and erases the color tone of the base material. There was a problem.

As a means to solve these problems, a transparent layer is coated on the surface of a colored layer with an uneven pattern to create a wood grain pattern by varying shading, or a thin film sheet with a pattern is laminated on the surface to create a pattern. However, these methods require complicated and expensive molding, and do not sufficiently solve the problem of monotony.

[0006] This invention was made in view of the above circumstances, and can be easily molded, and based on the color tone of the inner layer,
The object of the present invention is to provide a synthetic resin architectural decorative material that exhibits a three-dimensional and soft metallic feel.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the synthetic resin architectural decorative material of the present invention includes an inner layer made of a colored opaque synthetic resin and an integrally formed surface of the inner layer. It consists of a surface layer made of a transparent synthetic resin to be coated, and a metallic pigment and a pearl pigment are added to the surface layer so as to give orientation to each other.

In the present invention, the metallic pigment may be the metal foil itself as long as it is added to the surface layer with orientation, but it is preferable that the metallic pigment is added to the surface of the metal layer with corrosion resistance and a surface layer. It is better to use a flat chip coated with a transparent synthetic resin layer having an affinity for . In this case, the metal layer may be, for example, a metal foil such as aluminum foil, copper foil, nickel foil, gold foil, or silver foil, or may be a PET film with aluminum vapor-deposited. In this case, the shape of the flat chip may be rectangular, square, triangular, circular, etc., but it is necessary that all the shapes are at least the same.

[0009] The above-mentioned pearl pigment is a pigment that differs in optical properties from ordinary coloring pigments and imparts pearlescent luster through regular multiple reflections, and can be formed, for example, by coating the surface of mica with titanium oxide. The above-mentioned metallic pigment may have any size as long as it is visually visible, and the amount added may also be arbitrary, but preferably the size of the single metallic pigment is 100 to 500 μm, and the surface It is preferable that the amount added in the layer is 0.1 to 0.5 parts by weight. The pearl pigment alone may have different shapes and sizes, but it is preferably in the form of regular scales, and the size is about 1/10 of the metallic pigment, that is, 10 to 50 μm.
m is preferably 10 to 20 μm, and the amount added in the surface layer is preferably 0.01 to 0.03 parts by weight.

0010

[Function] According to the synthetic resin architectural decorative material of the present invention constructed as described above, the transparent synthetic resin surface layer is integrally coated on the surface of the colored opaque synthetic resin inner layer. By adding metallic pigments and pearl pigments with orientation, the metallic feel of the large particle size metallic pigment and the pearlescent luster of the small particle size pearl pigments are synergized based on the color tone of the inner layer. By doing this, a decorative material with a three-dimensional and soft metallic color tone can be obtained, which can be used not only for handrails such as handrail caps and caps, but also for a wide range of architectural decorative materials.

[0011] In addition, a single metallic pigment is formed on the surface of a metal layer using a flat chip coated with a transparent synthetic resin having corrosion resistance and affinity with the surface layer, and a pearl pigment is formed on the surface of mica with titanium oxide. By forming coated micro flat chips and making each flat surface a transparent surface,
Since the light reflection angle is kept constant and the reflection efficiency is increased by adding a small amount, the color of the inner layer can be seen through without being inhibited by these pigments. Furthermore, deterioration of the chip due to corrosion or deterioration of the surface layer made of transparent synthetic resin material can be prevented.

[0012] Also, the size of the single metallic pigment is 1
00 to 500 μm, and the amount added in the surface layer is 0.
．． 1 to 0.5 parts by weight, the size of the pearl pigment alone is about 1/10 that of the metallic pigment, and the amount added in the surface layer is 0.01 to 0.03 parts by weight,
By adding metallic pigments and pearl pigments efficiently, making the particle size of the metallic pigment large enough to make its chips visible, and reducing the particle size of the pearl pigment, the color tone of each pigment and the color tone of the inner layer can be differentiated. are mixed three-dimensionally, giving the viewer a soft metallic feel.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an exploded perspective view of the decorative material of the present invention used in a Kasagi cover.

[0015] The Kasagi cover 1, which is a decorative material of the present invention, has the following features:
It is composed of an internal layer 3 having an arcuate cross section that is covered on the upper surface of the metal metal base 2, and a surface layer 4 that is integrally coated on the surface of this internal layer 3.

The inner layer 3 is made of a colored opaque synthetic resin, such as soft or semi-hard vinyl chloride. In this case, a small amount of a coloring pigment (phthalocyanine green) based on titanium oxide can be used to give the inner layer 3 a green pastel color, for example.

As shown in FIGS. 2 to 4, the surface layer 4 is made of a transparent synthetic resin in which metallic pigments 5 are added with orientation, and pearl pigments 5a are added with orientation in the gaps between the metallic pigments 5. For example, it is made of vinyl chloride.

In this case, the metallic pigment 5 is made of a rectangular flat metal foil 6 whose surface is coated with a transparent synthetic resin layer 7 having corrosion resistance and affinity with the surface layer 4, as shown in FIG. It is made of shaped chips. For example, the metal foil 6 has a thickness of about 12 μm, and the vertical and horizontal dimensions are 100 μm×14
0 μm aluminum foil is used to give it a white color.

Note that the metal foil 6 does not necessarily have to be aluminum foil, but may be copper foil (copper color), nickel foil (aluminum color), gold foil (gold color), or silver foil (silver color) depending on the desired color. ) can be used.

In addition, the synthetic resin layer 7 having corrosion resistance and affinity has corrosion resistance to prevent reflection deterioration due to oxidation on the surface of the metal foil 6, and also has corrosion resistance to prevent reflection deterioration due to oxidation of the surface of the metal foil 6. It is necessary to prevent precipitation on the surface side of the layer 4 to confine the metal foil 6 and to be compatible with the vinyl chloride of the surface layer 4. As this synthetic resin, an acrylic resin is generally used, but a plasticizer may also be used. However, the condition is that it be transparent. In addition, the synthetic resin layer 7 may be colorless or colored as long as it is transparent.
If it is colored, it is necessary to avoid colors that inhibit the reflection of metallic pigments, such as dark colors, and to select pigments that tend to cause reflection of metallic pigments.

The vertical and horizontal dimensions of the single metallic pigment 5 are not limited to the above-mentioned 100 μm×140 μm, but may be in the range of 100 μm to 500 μm. Also,
As long as the metallic pigment 5 is flat, its shape does not necessarily have to be rectangular, and may be any shape such as a square, a triangle, or a circle. However, all shapes must be the same. By making the metallic pigment 5 flat and giving it orientation, the flat surface becomes a transparent surface, making it possible to maintain a constant light reflection angle and improve reflection efficiency with a small amount added.

[0022] In the above explanation, a case has been described in which the metallic pigment 5 is coated with a transparent synthetic resin layer having corrosion resistance and affinity on the surface of the metal foil 6, but it is not necessarily necessary to have such a structure. For example, as shown in FIG. 6, a transparent synthetic resin layer 10 having corrosion resistance and affinity may be coated on the surface of an aluminum vapor-deposited layer 9 in which aluminum is vapor-deposited on a PET film 8.

On the other hand, the pearl pigment 5a is formed by coating the surface of a scale-like mica 5b with titanium oxide 5c, as shown in FIG. Although the shape and size of this single pearl pigment 5a may be slightly different, it is preferable that it has fixed shape, and its size is about 1/10 of that of the metallic pigment 5.
That is, it is preferably 10 to 50 μm, preferably 10 to 20 μm.

When light is incident on the pearl pigment 5a formed in this way, the first light is reflected by the flat surface of the pearl pigment 5a, and the second light passes through the titanium oxide 5c and is absorbed by the mica. The third light is reflected on the surface of the pearl pigment 5b, and the third light is reflected on the bottom surface of the pearl pigment 5a. Therefore, these three
Pearlescent luster can be imparted by regular multiple reflections of light from seeds.

Metallic pigment 5 formed as described above
The blending ratios of pearl pigment 5a and pearl pigment 5a are as follows.

That is, the amount of the metallic pigment 5 added in the surface layer 4 is 0.1 to 0.5 parts by weight, and the pearl pigment 5a is
The amount added in the surface layer 4 is 0.01 to 0.03 parts by weight.

Next, a process of manufacturing the Kasagi cover 1 by integrally molding the inner layer 3 and the surface layer 4 formed as described above will be explained.

First, a metallic pigment 5 and a pearl pigment 5a are added to a vinyl chloride resin resin together with a plasticizer, a stabilizer, and a lubricant.
is added and mixed in a mixer to produce a powder compound, and then this powder compound is plasticized and melted in a kneading extruder to produce a pellet compound with a diameter of about 2 to 3 mm, and the surface layer 4 is formed. The pellet compound for the inner layer is manufactured using almost the same process as the compound.

Next, when the pellet compounds of the surface layer 4 and the inner layer 3 are simultaneously molded using an extrusion molding machine, the surface layer 4 is integrally laminated on the surface of the inner layer 3 and the Kasagi cover 1 is formed. molded. At this time, when the metallic pigment 5 in the surface layer 4 is molded, it is mixed so that its flat surface is a transparent surface and has orientation in the length direction, and
The pearl pigments 5a are also mixed into the gaps between the metallic pigments 5 which are similarly aligned with a certain orientation. Note that the metallic pigment 5 and the pearl pigment 5a are arranged on the inner side of the surface layer 4 (see FIG. 4). Here, since the metallic pigment 5 and the pearl pigment 5a are arranged on the inner side of the surface layer 4, even if the surface is scratched, the scar can be made difficult to see.

[0030] Then, by placing the cap cover 1 on the metal base 2, the cap of the handrail can be formed (Figs. 8 and 9).
reference).

[0031] Note that the support post 10 of the handrail can also be covered with a decorative material in the same way as the Kasagi cover 1, and the end cap 11 provided at the end of the handrail can also be covered with a decorative material. . In this case, the end cap 11
is molded by injection molding.

In the surface layer 4 of the handrail Kasagi cover 1 and end cap 11 formed as described above, the light that passes through the transparent part of the surface layer 4 and enters the surface of the inner layer 3 is as shown in FIG. As shown by the solid line in FIG. It is reflected at a specular reflection angle θ that is symmetrical with respect to the angle θ. Further, the light transmitted through the surface layer 4 and incident on the pearl pigment 5a undergoes regular multiple reflections as described above (indicated by broken lines in FIG. 4). Therefore, the color (green) of the inner layer 3 is recognized by the light reflected from the inner layer 3, and based on this color, the metallic color due to the light reflected from the metallic pigment and the pearlescent luster from the pearl pigment are recognized. The three colors are mixed three-dimensionally, giving the handrail a silky, soft tone to the viewer.

[0033] In the above embodiment, the case where the decorative material of the present invention is used as a handrail cap cover is explained, but of course, other than the cap cover, it can also be used for ceiling parting materials, around stairs, skirting boards, sizing materials, and clothes lines. It can be used for multiple purposes such as rods and pipes for various purposes.

[0034]

[Effects of the Invention] As explained above, since the synthetic resin architectural decorative material of the present invention is constructed as described above,
The following effects can be obtained.

1) According to the synthetic resin architectural decorative material according to claim 1, the transparent synthetic resin surface layer integrally coats the surface of the colored opaque synthetic resin inner layer. Pigments and pearl pigments are added with orientation, so based on the color of the inner layer, the metallic feel of the large particle size metallic pigment and the pearlescent luster of the small particle size pearl pigment are synergized. It is possible to form a decorative material that has a three-dimensional and soft metallic color tone.

2) According to the synthetic resin architectural decorative material according to claim 2, a metallic pigment and a pearl pigment are added to the transparent surface layer, and the metallic pigment is applied to the metal surface to improve corrosion resistance and improve the surface layer. The flat chips are coated with a transparent synthetic resin that has an affinity with the resin part, and the pearl pigment is formed by micro flat chips whose mica surface is coated with titanium oxide. Since the shaped surface is a transparent surface, the reflection efficiency is increased by a small amount of addition while keeping the reflection of light constant, so that the color of the inner layer can be seen through from the outside without being inhibited by these pigments. Furthermore, it is possible to prevent the decorative material from peeling off due to corrosion or deterioration.

3) According to the synthetic resin architectural decorative material according to claim 3, the size of the metallic pigment and the pearl pigment and the amount added in the surface layer are controlled efficiently so as not to impair the color of the inner layer. By increasing the particle size of the added metallic pigment to the extent that its chips are visible and reducing the particle size of the pearl pigment, these three colors are mixed three-dimensionally, giving the viewer a metallic tone. It can give a sense of bold and soft color tones.
