Abstract

Epoxidized natural rubber (ENR) and solution styrene butadiene rubber were blended with a ratio of 150:50, which filled with silica and carbon black as reinforcement fillers. The curing properties of the rubber composites were tested by rubber processing analyzer and the morphological structure was characterized by SEM. The thermal decomposition behavior, tensile strength, hardness value, friction coefficient and resilience property were investigated to verify the property improvement of the SSBR/ENR composites. From the results of all the tests, it can be found that the heat resistance, hardness value, tensile strength and filler dispersion state of composites increased with increasing content of silica. The possible reason may be due to the fact that the silica could provide the better combination with ENR part due to the formation of hydrogen bond formation from O-Si-O. And with the increasing content of carbon black, the friction coefficient and resilience property were improved due to the lubrication and coupling effect of carbon black and blends.


에폭시화 천연고무(ENR)와 솔루션-스디렌-부다디엔 고무(SSBR)를 150:50로 혼합한 고무 블렌드를 실리카 및 카본블랙을 충전제로 보강하였다. 제조된 고무 복합체의 물성은 고무 가공 분석기로 측정되었고, 형태학적 구조는 SEM으로 확인되었다. 열무게 분석, 인장강도, 경도, 마찰계수 및 발반탄성은 ENR/SSBR 블렌드의 물성을 확인하기 위하여 조사되었다. 모든 실험 결과에서, 복합체의 내열성, 경도, 인장강도 및 충전제의 분산성은 실리카 함량이 증가함에 따라 향상되었음을 알 수 있었다. 그 원인은 실리카와 ENR부분 사이에 수소 결합이라는 더 나은 결합의 형성이었다. 또한 블렌드의 마찰계수과 발반탄성은 카본블랙 함량이 증가함에 따라 향상되었다. 그 원인은 카본블랙과 블렌드의 결합효과(coupling effect) 및 윤활성이 개선됨에 기인함을 알았다.
