Abstract
Description
본 발명은 폐타이어를 각종 약품과 혼합, 용융시켜 사출 성형하여 각종 판넬이나 관 등과 같은 여러가지 제품을 제조할 수 있는 폐타이어를 이용한 사출 성형물 제조방법에 관한 것이다.The present invention relates to a method for producing an injection molded product using waste tires, which can produce various products such as various panels and tubes by injection molding by mixing and melting waste tires with various chemicals.
타이어를 사용하고 못사용하게 된 폐타이어를 현재는 소각 처리하거나 가늘게 절단하여 로우프 등을 제조하는 용도나 고무 바구니를 만드는 용도 등으로 사용하여 왔었다.Waste tires, which have been used tires and can not be used, have now been used for incineration or thin cutting to produce ropes, or for making rubber baskets.
그러나 이와 같은 용도에는 한계가 있는 것으로 수많은 자동차에서 배출되는 타이어를 전량 사용하기란 거의 불가능하여 그중 일부만 재사용되고 나머지는 소각 처리하여 공해에 심각한 오염을 초래하게 되는 것이다.However, there is a limit to such use, and it is almost impossible to use all the tires emitted from many automobiles, only some of them are reused and others are incinerated, causing serious pollution to the pollution.
한편 폐타이어 분말을 합성수지와 혼합 재생하는 방법은 일본국 공개특허공보 소 51-17994호 및 일본국 공개특허공보 소 55-135625호에도 개시되어 있으나, 상기 방법들에서는 첨가제 및 폐타이어 분쇄물과 합성수지간의 배합비가 달라서 본 발명과 같은 경도가 강하고 내구성이 있는 제품 물성이 발현되지 못하는 문제점이 있었다.Meanwhile, a method of mixing and recycling waste tire powder with a synthetic resin is disclosed in Japanese Patent Laid-Open Publication No. 51-17994 and Japanese Patent Laid-Open Publication No. 55-135625, but in the above methods, additives, waste tire grinds, and synthetic resin are used. Since the compounding ratio of the liver is different, there is a problem in that the hardness and hardness of the product properties such as the present invention are not expressed.
본 발명은 상기와 같은 문제점을 해소하기 위하여 개발된 것으로 폐타이어를 미분쇄하여 여기에 각종 물질 및 약품을 투여한 후 용융시켜 또는 사출 성형하여 각종 산업구조물을 제조함으로써 폐타이어를 재생하여 산업에 유용한 자원으로 전환시키고자 함에 있다.The present invention was developed in order to solve the above problems, finely pulverize waste tires, and administer various materials and chemicals to them, and then melt or inject mold to manufacture various industrial structures to recycle waste tires, which are useful for industries. It's about turning it into a resource.
본 발명의 다른 목적은 폐타이어 소각에 따른 에너지 손실 및 환경공해를 방지하고자 함에 있다.Another object of the present invention is to prevent energy loss and environmental pollution caused by incineration of waste tires.
본 발명의 폐타이어를 이용한 사출 성형물 제조방법은 폐타이어 분쇄물, 합성수지 및 첨가제를 혼합하여 이루어지는 폐타이어를 이용한 사출 성형물 제조방법에 있어서, 폐타이어 분쇄물에 폴리프로필렌 수지(PP), 저밀도 폴리에틸렌 수지(LDPE) 및 고밀도 폴리에틸렌 수지(하이덴, HDPE)중 하나 이상과 아세톤, 가성소다, 유리석면 및 전지분을 혼합하여 섞은 후 약 230℃ 내지 310℃에서 용융시켜 사출 성형을 행하는 것을 특징으로 하고 있다.The injection molding method using the waste tire of the present invention is a method for producing an injection molding using waste tire, which is a mixture of waste tire pulverized product, synthetic resin and additives, wherein the waste tire pulverized product is made of polypropylene resin (PP) and low density polyethylene resin. (LDPE) and at least one of a high density polyethylene resin (Hyden, HDPE) and acetone, caustic soda, glass asbestos and battery powder are mixed and melted at about 230 ℃ to 310 ℃ characterized in that the injection molding.
상기 폐타이어 분쇄물의 입자크기는 용도에 따라 적합하게 조정하며, 통상 입경이 2 내지 3mm 정도가 적합하다. 또한 상기 폐타이어 분쇄물의 함량은 35 내지 45중량%로 하는 것이 바람직하다.The particle size of the waste tire pulverized product is suitably adjusted according to the use, and a particle size of about 2 to 3 mm is usually suitable. In addition, the content of the waste tire pulverized is preferably set to 35 to 45% by weight.
상기 폴리프로필렌 수지 및 저밀도 폴리에틸렌 수지(LDPE)는 폐수지를 이용할 수도 있으며, 그 함량은 각각 18 내지 23중량%로 하는 것이 바람직하고, 상기 고밀도 폴리에틸렌(하이덴, HDPE)은 0 내지 13중량%로 하는 것이 바람직하다.The polypropylene resin and the low density polyethylene resin (LDPE) may use waste resins, the content of which is preferably 18 to 23% by weight, and the high density polyethylene (heden, HDPE) is 0 to 13% by weight. desirable.
또한 상기 수지들 대신에 또는 부가하여 나이론 등의 수지를 사용하는 것도 가능하다. 상기 아세톤, 가성소다, 유리석면 및 전지분은 제품 목적에 따라 이들 중 하나 또는 둘 이상이 선택적으로 사용될 수 있다.It is also possible to use resins such as nylon instead of or in addition to the above resins. The acetone, caustic soda, glass asbestos and battery powder may be optionally used one or two or more of them depending on the purpose of the product.
상기 각 부가 물질의 농도는 명확히 한정할 수 있는 성질은 아니지만 대체로 아세톤은 0.01 내지 0.05중량%, 가성소자는 0.03 내지 0.08중량%, 유리석면은 4 내지 7중량%, 전지분은 3 내지 5중량%로 하는 것이 가장 바람직하다.The concentration of each additional material is not a property that can be clearly defined, but acetone is generally 0.01 to 0.05% by weight, caustic element is 0.03 to 0.08% by weight, glass asbestos is 4 to 7% by weight, battery powder is 3 to 5% by weight It is most preferable to set it as.
상기 부가 물질 중 아세톤은 용제로서 채용되는 것이며 가성소다는 성형물 내부에 다량의 미세한 기포를 형성시킴으로써 제품의 충격 흡수력을 증가시키고 제품의 탄력성을 향상시키는 역할을 한다.Acetone is used as a solvent among the additional substances, and caustic soda forms a large amount of fine bubbles in the molding, thereby increasing the impact absorption of the product and improving the elasticity of the product.
또한 유리석면은 내열성 재료로서 제품의 내열성을 증가시키는 역할을 하며, 그 함량이 과다하게 되면 제품이 조악해지고 성형성이 좋지 않게 된다. 그리고, 전지분은 전분과 같은 것으로서 본 발명의 제품이 사용되는 기간중 일정기간이 경과하면 고무성분 및 수지성분을 분해시킴으로써 환경오염을 방지하는 역할을 한다.In addition, glass asbestos serves to increase the heat resistance of the product as a heat-resistant material, when the content is excessive, the product becomes coarse and poor moldability. In addition, the battery powder is the same as starch, and serves to prevent environmental pollution by decomposing the rubber component and the resin component after a certain period of time during which the product of the present invention is used.
