Description
본 발명은 고무 조성물에 적용되는 폐고무 분말에 관한 것으로서, 폐타이어로부터 상온 분쇄법으로 제조된 폐고무 분말을 염소용액으로 처리하여 적용하므로써 고무 조성물의 균열 특성, 마모 특성, 기계적 성질 등을 향상시킬 수 있는 폐고무 분말에 관한 것이다.The present invention relates to a waste rubber powder applied to the rubber composition, by applying the waste rubber powder prepared by the normal temperature grinding method from the waste tire with a chlorine solution to improve the cracking properties, wear characteristics, mechanical properties, etc. of the rubber composition. It relates to a waste rubber powder that can be.
자동차 생산 증가에 따라 타이어 수요가 증가함에 따라 폐타이어의 처리문제는 최근 심각한 환경문제로 대두되고 있으며, 이러한 문제는 보다 사회적인 측면의 문제로 확대되어 세계 각국에서는 폐타이어 처리에 관한 각종 법률이나 규제를 만들어 이를 준수하도록 함과 동시에, 폐타이어가 미치는 제반 영향이나 폐타이어 처리방안 등의 연구에 재정적인 지원까지도 아끼지 않고 있는 실정이다. 이러한 배경하에 각종 환경보건 측면에서의 영향을 최소화하기 위해서 뿐만 아니라, 갈수록 고갈되고 있는 자원의 보존 측면에서도 폐타이어를 또 하나의 소중한 자원으로 인식하고 재활용 방안을 찾고자 하는 노력들이 현재 활발하다.As tire demand increases with the increase in automobile production, the disposal of waste tires has become a serious environmental problem in recent years, and these problems have become more social issues. In addition to making it comply with the above, financial support for research on waste tires' impact and waste tire disposal plans is being spared. Against this backdrop, efforts are being made to recognize waste tires as another valuable resource and to find ways to recycle them in addition to minimizing their impact on various environmental health aspects.
폐타이어의 재활용은 크게 열이용, 원형 이용, 분말가공 이용의 세가지로 분류할 수 있다. 이중에서 분말가공은 폐타이어를 분쇄하여 분말화 한 후 사용하는것으로서, 그 적용 분야가 상당히 광범위하다. 폐타이어 고무 분말의 특성을 향상시키고 보다 다양한 분야에 적용키 위해 폐타이어의 분쇄방법, 고무 분말의 표면처리, 탈황 방법 등에 관한 활발한 연구도 진행중이고, 고무 분말을 여러 분야에 적용한 결과도 보고되어 있다. 한편 이러한 고무 분말을 타이어용 고무 화합물에 적용하여 원가절감이나 환경문제의 해결에 기여하고자 하는 노력이 보다 미세한 입자 크기를 가지거나 특성이 향상된 고무 분말의 출현에 따라 더욱 심도 있게 진행되고 있다. 그러나 고무 분말을 적용하면 원 고무와의 상용성, 분산성, 계면에서의 접착력 결여 등에 의하여 배합된 고무의 기계적 물성이 하락하게 되는 문제점이 있다.The recycling of waste tires can be classified into three categories: heat use, prototype use, and powder use. Among these, powder processing is used after pulverizing waste tires and pulverizing them, and its field of application is quite extensive. In order to improve the characteristics of waste tire rubber powder and apply it to various fields, active researches on the crushing method of waste tire, surface treatment of rubber powder, desulfurization method, etc. are underway, and the results of applying rubber powder to various fields are reported. . On the other hand, the efforts to contribute to the reduction of cost or environmental problems by applying such rubber powder to the rubber compound for tire is proceeding in more depth as the appearance of rubber powder having a finer particle size or improved characteristics. However, when the rubber powder is applied, there is a problem that the mechanical properties of the rubber compounded due to compatibility with the original rubber, dispersibility, lack of adhesion at the interface, and the like.
본 발명의 목적은 상기와 같은 문제점을 개선하기 위한 것으로서, 폐타이어 고무 분말 적용시 고무 배합물의 물성 하락을 개선하기 위해서 폐고무 분말을 염소 용액으로 처리하여 적용하므로써 고무 조성물의 균열 특성, 마모 특성, 기계적 성질 등을 향상시킬 수 있는 폐고무 분말을 제공하는 것이다.An object of the present invention is to improve the problems as described above, in order to improve the physical properties of the rubber compound when the waste tire rubber powder applied by treating the waste rubber powder with a chlorine solution applied by cracking properties, wear characteristics, It is to provide a waste rubber powder that can improve the mechanical properties and the like.
본 발명은 고무 조성물에 적용되는 폐고무 분말에 관한 것으로서, 폐타이어로부터 상온 분쇄법으로 제조된 폐고무 분말을 염소용액으로 처리하여 적용하므로써 고무 조성물의 균열 특성, 마모 특성, 기계적 성질 등을 향상시킬 수 있는 폐고무 분말에 관한 것이다.The present invention relates to a waste rubber powder applied to the rubber composition, by applying the waste rubber powder prepared by the normal temperature grinding method from the waste tire with a chlorine solution to improve the cracking properties, wear characteristics, mechanical properties, etc. of the rubber composition. It relates to a waste rubber powder that can be.
본 발명의 폐고무 분말을 고무 조성물에 적용할 경우, 5∼25phr을 사용하는 것이 바람직한데, 폐고무 분말이 25phr을 초과할 경우에는 마모물성이 하락한다.When the waste rubber powder of the present invention is applied to the rubber composition, it is preferable to use 5 to 25 phr, but when the waste rubber powder exceeds 25 phr, wear property decreases.
폐타이어로부터 폐고무 분말을 제조할 때 적용되는 상온 분쇄법은 당분야에서 통상적으로 적용되고 있는 방법으로서, 실온에서 Open-Mill 또는 Two-Roll-Mill에서 전단력에 의한 분쇄법을 말한다.The normal temperature grinding method used when manufacturing waste rubber powder from waste tires is a method commonly applied in the art, and refers to a grinding method by shear force in Open-Mill or Two-Roll-Mill at room temperature.
본 발명에 있어서 폐고무 분말의 염소 용액에서의 처리 방법은, 염소용액에 폐고무 분말을 담그어 방치하였다가, 이를 꺼내어 암모니아 용액으로 중화한 후 증류수로 세척하고, 건조하는 것이다.In the present invention, a method for treating waste rubber powder in a chlorine solution is to immerse the waste rubber powder in a chlorine solution and to leave it, and then, it is taken out, neutralized with ammonia solution, washed with distilled water, and dried.
이렇게 처리된 폐고무 분말을 스티렌-부타디엔 고무(SBR), 부타디엔 고무(BR), 천연고무(NR), 이소프렌-이소부틸렌 고무, 할로부틸 고무 또는 이들의 2종 이상 혼합물을 주재로 하는 기본배합의 고무 조성물에 통상의 배합방법을 사용하여 믹서로 혼합하여 고무 조성물을 제조한다. 혼합시 고무 분말의 원고무상에서의 분산 및 분포도를 향상시키기 위해 먼저 주재료인 고무와 폐고무 분말을 미리 혼합하고, 이후 나머지 보강제나 약품 등을 투입하여 혼합하는 것이 바람직하다.The waste rubber powder thus treated is composed of styrene-butadiene rubber (SBR), butadiene rubber (BR), natural rubber (NR), isoprene-isobutylene rubber, halobutyl rubber or a mixture of two or more thereof. The rubber composition is prepared by mixing with a mixer using a conventional compounding method. In order to improve the dispersion and distribution in the rubber phase of the rubber powder during mixing, it is preferable to first mix the rubber and waste rubber powder as the main material in advance, and then mix and add the remaining reinforcing agents or chemicals.
