Description
본 발명은 다기능성 열가소성수지 및 그 제조방법에 관한 것으로, 상세하게는 열가소성수지(thermoplasticresin)에 솔잎입자와 소나무톱밥 및 황토를 혼합하여 양질의 합성수지판재를 얻을 수 있도록 하는 다기능성 열가소성수지 및 그 제조방법에 관한 것이다,The present invention relates to a multifunctional thermoplastic resin and a method for manufacturing the same. Specifically, a multifunctional thermoplastic resin for producing a high-quality synthetic resin plate material by mixing pine needle particles, pine sawdust and ocher in a thermoplastic resin (thermoplasticresin) It's about how,
일반적으로 열가소성수지는 가열하면 변형이 가능해지는 가소성이 커지는 합성수지로, 폴리에틸렌(polyethylene), 폴리염화비닐(polyvinylchloride), 폴리스티렌(polystyrene), 폴리 프로필렌(polypropylene) 등이 있다.In general, the thermoplastic resin is a plastic resin that can be deformed when heated, polyethylene, polyvinyl chloride, polystyrene, polypropylene and the like.
이러한 열가소성수지는 대부분 압출로 성형하게 되는데, 압출성형은 압출기의 호퍼에 칩 상태의 열가소성 수지를 투입하면 내부에서 가열되어 칩 상태의 열가소성수지가 녹아 융해되고 융해된 열가소성수지가 스크루의 회전으로 혼련·압축되면서 다이를 통과하게 되므로 다이에 결합된 금형에 의해 원하는 형상을 연속적으로 압출하면서 성형하게 되고, 성형된 물품은 냉각수조를 통과하면서 냉각되어지며 냉각된 성형품은 적정크기로 절단하여 제품을 완성하였다.Most of these thermoplastic resins are molded by extrusion, but extrusion molding is heated inside when the thermoplastic resin in the chip state is put into the hopper of the extruder, and the thermoplastic resin in the chip state is melted and melted, and the melted thermoplastic resin is kneaded by the rotation of the screw. As it passes through the die while being compressed, it is molded while continuously extruding a desired shape by a die bonded to the die. The molded article is cooled while passing through a cooling water tank, and the cooled molded product is cut to an appropriate size to complete a product. .
이러한 압출성형은 스크루가 한 개로 구성된 단축식이 대부분이나 목적하는 바에 따라 스크루가 두 개 또는 세 개인 이축식, 삼축식 등이 있다.The extrusion is mostly a single screw consisting of a single screw, but there are two or three screws, triaxial, etc., as desired.
성형방법으로는 압출성형, 사출성형, 압축성형 등이 있다.Molding methods include extrusion molding, injection molding, compression molding and the like.
한편, 폴리에틸렌은 제조법에 따라 밀도·성질이 다르게 되는데 이는 구조의 차이가 그 원인이다. 고압법으로는 분기(分岐)가 많은 선(線)형 고분자로 짧은 가지가 붙은 만들어지는 데 대해, 저압법으로는 직쇄형 폴리에틸렌이 얻어져 결정(結晶)화되기 어렵기 때문이다. 이 들의 성질은 연화점은 낮지만 물보다 가볍고 내충격성이 뛰어나 강하며, 내수성(耐水性)·내한성(耐寒性)·전기특성(電氣特性)도 뛰어나다. 현재 가장 일반적으로 수지로 이용된다. 저밀도 폴리에틸렌은 농업용필름·부엌용품·물통·테이프·완구 등에 사용되고, 고밀도 폴리에틸렌은 맥주상자·물통·줄테이프 및 슈퍼마켓 등의 포장용 금박필름 등에 사용된다.On the other hand, polyethylene is different in density and properties depending on the manufacturing method, which is due to the difference in structure. This is because the high pressure method is made of a linear polymer having many branches, and short branches are formed. However, the low pressure method makes it difficult to crystallize linear polyethylene. They have low softening point, but are lighter than water and have excellent impact resistance. They are also excellent in water resistance, cold resistance, and electrical characteristics. Currently most commonly used as a resin. Low density polyethylene is used for agricultural films, kitchen utensils, buckets, tapes, toys and the like, and high density polyethylene is used for packaging gold foil films for beer boxes, buckets, file tapes and supermarkets.
폴리스티렌은 단단하고 무색 투명하며 전기적 특성도 좋고, 대량생산으로 값이 싸기 때문에 주방용품·문구·가구 등의 일용품, 자동차용의 대형 성형품, 텔레비전캐비닛 등의 전화제품(電化製品) 등 많은 곳에 사용되고 있다. 부탄·펜탄·헥산 등의 발포제를 배합하여 가열발포시킨 발포폴리스티렌도 단열재·완충재·돗자리·깔개 등으로 쓰인다. 또한 목재대용으로 사용되는 저발포품은 기계·전화제품 등의 포장용 완충재로 사용되는 고발포품에 이르기까지 사용범위가 넓으며, 저발포시트는 합성지로도 사용된다. Polystyrene is hard, colorless and transparent, and has good electrical characteristics, and is cheap in mass production, so it is used in many places such as daily necessities such as kitchen appliances, stationery, furniture, large molded articles for automobiles, and telephone products such as television cabinets. have. Foamed polystyrene, which is foamed with a blowing agent such as butane, pentane, and hexane, is also used as a heat insulating material, a buffer material, a mat, and a mat. In addition, the low-foaming product used as a substitute for wood has a wide range of use, ranging from a high-foaming product used as a cushioning material for packaging such as machinery and telephone products, and a low-foaming sheet is also used as a synthetic paper.
폴리염화비닐에는 가소제를 거의 첨가하지 않은 경질(硬質) 폴리염화비닐과 가소제를 다량 첨가한 연질 폴리염화비닐이 있다. 난연성(難燃性)·내수성이며 열이나 빛에 분해되어 염화수소를 발생시킨다. 연소할 때에도 자극성·부식성 염화수소가스를 발생하므로 건축재료로 쓰거나 폐기처리 때 문제가 된다. 경질폴리염화비닐은 건축자재·레코드판·용기 등의 성형품으로 쓰인다. 연질 폴리염화비닐은 전선피복·구두·농업용 필름·스트래치 필름 등으로 쓰인다.Polyvinyl chloride includes hard polyvinyl chloride with almost no plasticizer and soft polyvinyl chloride with a large amount of plasticizer. It is flame retardant and water resistant and decomposes in heat or light to produce hydrogen chloride. Irritating and corrosive hydrogen chloride gas is also generated during combustion, which is a problem when used as a building material or disposed of. Rigid polyvinyl chloride is used as molded products for building materials, record plates and containers. Soft polyvinyl chloride is used for wire coating, shoes, agricultural film and stretch film.
폴리프로필렌은 폴리에틸렌·폴리염화비닐·폴리스티렌과 함께 4대 플라스틱의 하나이다. 폴리프로필렌은 물리적 성질이 폴리에틸렌보다 뛰어나지만 산소 존재하에서 빛이나 열에 산화열화(酸化劣化)하는 결점이 있으며 안정제(安定劑)를 필요로 한다. 한편 비중이 0.9정도로 가장 가벼운 플라스틱이며 강성·내충격성·전기적 특성이 뛰어나고 값이 싸 이용범위가 넓으며 이축연신(二軸延伸) 폴리프로필름으로서 필름 분야, 플랫얀(flatyarn) 카펫 등의 섬유분야, 컨테이너·약전부품(弱電部品) 등의 사출성형(射出成形) 분야에 주로 이용된다. 최근에는 고무·필터와의 복합물이 자동차 범퍼, 그 밖의 자동차부품, 패널 등 대형 공업부품으로 이용이 확대되고 있다.Polypropylene is one of four plastics together with polyethylene, polyvinyl chloride, and polystyrene. Polypropylene is superior to polyethylene in physical properties, but has the disadvantage of oxidative deterioration in light or heat in the presence of oxygen and requires a stabilizer. On the other hand, it is the lightest plastic with a specific gravity of about 0.9, and has excellent rigidity, impact resistance, and electrical characteristics, and it is cheap and has a wide range of use.It is a biaxially oriented polypropylm, which is used in the film field and the flaty carpet. It is mainly used in the field of injection molding of container, pharmacy parts and the like. In recent years, composites with rubber and filters have been increasingly used as large industrial parts such as automobile bumpers, other automobile parts, and panels.
그러나 이러한 열가소성수지는 그 용도가 건축 마감자재로 사용되는 경우, 그 형상 및 기능이 단순하여 수요자의 다양한 욕구를 충족시키지 못한 문제점이 있었다.However, when the thermoplastic resin is used as a building finishing material, the thermoplastic resin has a problem in that the shape and function of the thermoplastic resin are not sufficient to satisfy various needs of the consumer.
특히 열가소성수지를 재활용하는 경우에는 저렴한 가격에 생산 공급할 수 있으나 그 기능이 현저히 감소되는 단점이 있었다. In particular, in the case of recycling the thermoplastic resin can be produced and supplied at a low price, but the function was significantly reduced.
따라서 본 발명의 주 목적은 인체에 유익하고 무해 무독한 다기능성의 합성수지를 제공할 수 있도록 하는 데 있다.Therefore, the main object of the present invention is to provide a multifunctional synthetic resin that is beneficial and harmless to the human body.
본 발명의 다른 목적은 폐기된 열가소성수지를 재활용하여 다기능성 제품을 제조할 수 있도록 하여 환경오염을 억제할 수 있도록 하는 데 있다.Another object of the present invention is to recycle the discarded thermoplastic resin to produce a multifunctional product to suppress environmental pollution.
본 발명의 다른 목적은 원적외선과 방향(芳香)기능을 지속적으로 작용하는 다기능성 열가소성수지를 제공하는 데 있다.Another object of the present invention is to provide a multifunctional thermoplastic resin that continuously functions as a far infrared ray and aroma function.
본 발명의 다른 목적은 저렴한 가격으로 다기능성 열가소성수지를 제공하는 데 있다.Another object of the present invention is to provide a multifunctional thermoplastic at a low price.
본 발명의 다른 목적은 합성수지의 표면 문양을 다양화 할 수 있도록 하는 데 있다. Another object of the present invention is to enable to vary the surface pattern of the synthetic resin.
이러한 목적을 달성하기 위하여 본 발명의 다기능성 열가소성수지 및 그 제조방법은 열가소성수지에 솔잎입자와 양질의 황토 및 소나무 톱밥을 혼합하여 다양한 제품을 생산하도록 함을 그 기술적 구성상의 기본 특징으로 한다.In order to achieve this object, the multifunctional thermoplastic resin of the present invention and its manufacturing method are characterized by the basic characteristics of the technical composition to produce a variety of products by mixing pine needle particles with high quality ocher and pine sawdust in the thermoplastic resin.
이러한 본 발명의 실시 예를 상세히 설명하면 다음과 같다.When explaining the embodiment of the present invention in detail as follows.
본 발명의 다기능성 열가소성수지는 열가소성수지 55중량%와, 소나무 톱밥20중량%와, 솔잎입자15중량%, 및 황토10중량%로 구성된다.The multifunctional thermoplastic resin of the present invention is composed of 55% by weight of thermoplastic resin, 20% by weight of pine sawdust, 15% by weight of pine needle particles, and 10% by weight of ocher.
여기서 소나무 톱밥은 완전 건조된 상태로 직경이 1.2mm에서 2.3mm 정도가 바람직하다.Here, pine sawdust is preferably in a completely dried state of about 1.2mm to 2.3mm in diameter.
소나무 톱밥의 입자가 2.3mm를 초과하는 경우에는 용해된 열가소성수지의 침투가 불안정하고, 1.2mm미만인 경우에는 톱밥 상호 지지력이 떨어지므로 제조된 합성수지의 강도가 저하된다.If the particle size of pine sawdust exceeds 2.3mm, the penetration of the dissolved thermoplastic resin is unstable, and if it is less than 1.2mm, the sawdust mutual support strength is lowered, and thus the strength of the manufactured synthetic resin is lowered.
솔잎입자는 자연상태의 솔잎을 잘 건조시키고 완전히 건조된 후 직경 0.5mm에서 1.2mm정도로 분쇄하여 사용함이 바람직하다.Pine needle particles are preferably used to dry the pine needles in the natural state and completely dried and then pulverized to about 0.5mm to 1.2mm in diameter.
솔잎입자가 0.5mm미만인 경우에는 솔 향기의 지속성이 현저하게 떨어지고, 1.3mm초과하는 경우에는 제조된 합성수지의 강도가 저하된다.If the pine needle particles are less than 0.5mm, the persistence of the scent of the brush is remarkably inferior, and if it exceeds 1.3mm, the strength of the manufactured synthetic resin is lowered.
황토는 물탱크에 투입 및 교반하여 현탁시킨 다음, 중력에 의한 침강에 의해 큰 입자들이 침전되도록 방치한 후에 수중에 부유되어 있는 미세황토입자를 하류의 물탱크로 흘려 보냄으로써 일차적으로 큰 입자와 작은 입자를 분리시키되 이러한 부유분리를 반복하여 마지막으로 물탱크에 유입된 미세황토입자를 장시간 방치하여 침전시킨 다음 침전이 완료되면 상층의 물을 제거하고 침전된 미세황토분말을 케이크 상태로 건조시킨 후에 분쇄하여 10㎛ 이하의 직경을 가지는 황토파우더를 완성한다.The ocher is suspended by pouring into the water tank, stirring it, and allowing the large particles to settle by gravity sedimentation, and then flowing the fine ocher particles suspended in the water to the downstream water tank, thereby primarily displacing the large and small particles. Separate the particles, but repeat this suspended separation, and finally settle by leaving the fine ocher particles introduced into the water tank for a long time, and when the precipitation is completed, the water of the upper layer is removed, and the precipitated fine ocher powder is dried to a cake state and pulverized. To finish the ocher powder having a diameter of 10㎛ or less.
이러한 본 발명의 다기능성 열가소성수지 제조방법은 폐 열가소성수지를 포집하여 통상의 압출기로 소정크기의 칩 상태로 열가소성수지를 생산한다.The multifunctional thermoplastic resin manufacturing method of the present invention collects the waste thermoplastic resin to produce the thermoplastic resin in a chip state of a predetermined size by a conventional extruder.
여기서 열가소성수지40-55중량%와, 소나무 톱밥20-28중량%와, 솔잎입자15-20중량%, 및 황토10-12중량%를 호퍼를 통해 압출기 내부로 공급하고 압출기를 작동시킨다. Here, 40-55% by weight of thermoplastic resin, 20-28% by weight of pine sawdust, 15-20% by weight of pine needle particles, and 10-12% by weight of ocher are fed into the extruder through the hopper and the extruder is operated.
이때 압출기의 내부에서 가열되어 칩 상태의 열가소성수지가 녹아 융해되고 융해되므로 소나무 톱밥과 솔잎입자 및 황토파우더에 흡착되면서 스크루의 회전으로 혼련·압축된다.At this time, the thermoplastic resin in the chip state is melted and melted by being heated inside the extruder, so as to be adsorbed by pine sawdust, pine needle particles and ocher powder, kneaded and compressed by screw rotation.
완전히 압축된 용해물은 다이를 통과하게 되고 다이에 결합된 금형에 의해 원하는 굵기로 연속하여 압출되고 이를 냉각하면서 절단하여 다기능성 열가소성수지를 칩 형태로 생산한다.The fully compressed melt is passed through a die and subsequently extruded to the desired thickness by a mold attached to the die and cut while cooling to produce a multifunctional thermoplastic in the form of chips.
여기서 압출기의 내부온도는 120-160℃정도가 가장 이상적이다.The ideal temperature inside the extruder is about 120-160 ° C.
한편 열가소성수지가 45중량%를 미만인 경우에는 원래의 열가소성수지의 특성이 현저하게 낮아질 뿐만 아니라 강도가 현격하게 저하된다.On the other hand, when the thermoplastic resin is less than 45% by weight, not only the properties of the original thermoplastic resin are significantly lowered but also the strength is significantly lowered.
또한 열가소성수지가 55중량%를 초과하는 경우에는 본 발명이 얻고자하는 다기능성의 효과와 지속성이 반감된다.In addition, when the thermoplastic resin exceeds 55% by weight, the effect and persistence of the multifunctionality to be obtained by the present invention are halved.
더불어, 열가소성수지가 45-50중량%인 경우에는 소나무 톱밥이 25중량% 이상으로 투입하여야만 일정 이상의 강도를 유지할 수 있다.In addition, when the thermoplastic resin is 45-50% by weight, the pine sawdust should be added at 25% by weight or more to maintain a certain strength or more.
소나무 톱밥의 경우에는 20중량%를 미만인 경우에는 상호 지지력이 떨어지므로 유의하여야 하고, 28중량%를 초과하는 경우에는 열가소성수지의 흡착력이 저하되어 강도가 떨어지게 된다.In the case of pine sawdust less than 20% by weight, since the mutual support capacity is lowered, it should be noted that, if it exceeds 28% by weight, the adsorption power of the thermoplastic resin is lowered and the strength is lowered.
솔잎입자의 경우에는 15-20중량% 정도가 적정강도를 보존한 상태에서 방향기능을 장기간 유지될 수 있다.In the case of pine needle particles, about 15-20% by weight can maintain the aromatic function for a long time while maintaining the appropriate strength.
즉, 솔잎입자가 15중량% 미만인 경우에는 방향기능 및 그 지속성이 현저하게 저하되고, 20중량%를 초과하는 경우에는 제조되는 다기능성 열가소성수지의 강도가 일정 수준이하로 떨어지게 된다.That is, when the pine needle particles are less than 15% by weight, the aromatic function and its persistence are significantly lowered, and when the pine needle particles are more than 20% by weight, the strength of the multifunctional thermoplastic resin to be produced falls below a certain level.
황토의 경우에는 10-12중량% 정도가 적정강도를 보존한 상태에서 원적외선 기능을 장기간 유지될 수 있다.In the case of loess, 10-12% by weight can maintain the far-infrared function for a long time while maintaining the appropriate strength.
즉, 황토가 10중량% 미만인 경우에는 원적외선 기능이 저하되고, 12중량%를 초과하는 경우에는 제조되는 다기능성 열가소성수지의 강도가 일정 수준이하로 떨어지게 된다.That is, when the ocher is less than 10% by weight, the far infrared function is lowered, and when the amount is more than 12% by weight, the strength of the multifunctional thermoplastic resin to be produced falls below a certain level.
이렇게 제조된 칩상태의 다기능성 열가소성수지는 압출기에 투입하여 압출성형하게 되는데 금형에 따라 다기능성 선재나 판재 등을 연속적으로 생산할 수 있다.The multifunctional thermoplastic resin in the chip state thus prepared is extruded into an extruder, and according to the mold, it is possible to continuously produce a multifunctional wire or plate.
나아가 다기능성 열가소성수지를 칩상태로 성형할 때 직접 다기능성 선재나 판재로 성형할 수 도 있으나 완전한 혼련과, 혼합물(소나무 톱밥, 솔잎, 황토)과의 흡착을 완전하게 실행하기 위하여 다기능성 열가소성수지를 칩상태로 제조한 후 이를 다시 압출기에 투입하여 원하는 형상의 제품을 제조함이 바람직하다.Furthermore, when forming a multifunctional thermoplastic resin into a chip state, it may be directly formed into a multifunctional wire rod or a sheet. However, in order to completely perform kneading and adsorption of a mixture (pine sawdust, pine needles, loess), the multifunctional thermoplastic resin It is preferable to prepare the product of the desired shape by preparing a chip state and then put it back to the extruder.
여기서 압출기의 내부온도는 120-160℃정도가 가장 이상적이다.The ideal temperature inside the extruder is about 120-160 ° C.
한편 판재나 선재 등의 경우에는 표면을 연마하여 무늬목 등의 시트를 부착하여 사용할 수 도 있다. On the other hand, in the case of a plate or wire rod, the surface may be polished to attach sheets such as veneer.
이상에서 살펴본 바와 같이, 본 발명의 다기능성 열가소성수지 및 그 제조방법은 열가소성수지 칩 55중량%와, 소나무 톱밥20중량%와, 솔잎입자15중량%, 및 황토10중량%를 압출기에 투입하여 다기능성 열가소성수지를 형성시키는 다기능성 칩형성단계, 및 상기 다기능성 칩을 압출기에 공급하여 금형의 형상에 따라 판재 등의 물품을 성형하는 다기능성 물품제조단계로 이루어짐으로, 인체에 유익하고 무해 무독한 다기능성의 열가소성수지를 제공할 수 있도록 할 뿐만 아니라 폐기된 열가소성수지를 재활용하여 선재나 판재를 제조할 수 있도록 하므로 환경오염을 억제할 수 있도록 하고 원적외선과 방향(芳香)기능을 지속적으로 유지할 수 있도록 하며 저렴한 가격과 간단한 방법으로 제조할 수 있도록 하고 표면 문양을 다양화 할 수 있는 효과가 있다. As described above, the multifunctional thermoplastic resin of the present invention and its manufacturing method is a 55% by weight of thermoplastic chips, 20% by weight of pine sawdust, 15% by weight of pine needle particles, and 10% by weight of ocher in the extruder Multi-functional chip forming step of forming a functional thermoplastic resin, and multi-functional article manufacturing step of molding the article, such as a plate according to the shape of the mold by supplying the multi-functional chip to the extruder, beneficial and harmless to humans In addition to providing a multifunctional thermoplastic resin, it is also possible to recycle the discarded thermoplastic resin to manufacture wire or plate materials so that environmental pollution can be suppressed and far infrared rays and fragrance can be maintained continuously. It can be manufactured at low cost and simple method, and it is effective to diversify the surface pattern.
