Description
본 발명은 폐기물로 발생하는 타이어용 EPDM 고무의 스크랩을 이용한 고충진 고무조성물에 관한 것이다. 보다 상세하게는 스크랩으로 발생한 EPDM 고무를 다량의 경질탄산칼슘과 다량의 클레이(Clay)를 첨가하여 배합한 후 활성제와 가류제 그리고 공정조제 등을 혼합하여 고충진 고무조성물에 관한 것이다.The present invention relates to a high-fill rubber composition using scrap of EPDM rubber for tires generated as waste. More specifically, the present invention relates to a high-fill rubber composition by mixing EPDM rubber generated as a scrap by adding a large amount of hard calcium carbonate and a large amount of clay and mixing an active agent, a vulcanizing agent, and a process aid.
본 발명과 관련된 종래기술은 보고된 바 없으나 대부분 스크랩으로 발생한 EPDM 고무는 폐기물로 소각되거나 매립하므로서 처리에 비용부담이 있고, 새로운 환경오염의 문제가 발생한다.Prior arts related to the present invention have not been reported, but most of the EPDM rubber produced as scrap is incinerated or landfilled as waste, and there is a problem of new environmental pollution.
타이어용 고무는 내산성과 내열성 그리고 내오존성이 높은 EPDM 고무를 생산할 때 고품질의 EPDM을 얻기 위하여 다량의 스크랩 EPDM이 폐기물로 발생한다. 이 스크랩 고무에 다량의 경질탄산칼슘, 클레이, 활성제, 가류제, 공정조제 등의 충진제를 첨가하고 발색제를 첨가하여 바닥재나 루핑(roopring)재로 활용될 수 있는 저렴한 칩(chip)을 제조할 수 있는 고무조성물을 제공한다.Rubber for tires generates a large amount of scrap EPDM as waste to obtain high quality EPDM when producing EPDM rubbers with high acid resistance, heat resistance and ozone resistance. This scrap rubber can be filled with a large amount of hard calcium carbonate, clay, activator, vulcanizing agent, process aid, etc., and a coloring agent can be added to make an inexpensive chip that can be used as a flooring or a roofing material. Provide a rubber composition.
에틸렌(Ethylene)과 프로필렌(Propylene)의 공중합체인 EPDM은 보통 에틸렌을 60∼70%, 프로필렌을 30∼40% 함유하는 불규칙(Random) 공중합체이지만 폴리머에서는 이중결합이 없어 황에 의한 가교반응이 불가능하여 황에 의한 가류반응이 되도록 이중결합을 가진 디엔(Diene)을 중합시켜 3원 공중합체로 한 것이 EPDM이다.EPDM, a copolymer of ethylene and propylene, is usually a random copolymer containing 60 to 70% of ethylene and 30 to 40% of propylene. EPDM is a terpolymer obtained by polymerizing a diene having a double bond so as to undergo a vulcanization reaction by sulfur.
