炭黑品种对ACM/ECO并用胶性能的影响

研究炭黑品种对ACM/氯醚橡胶（ECO）并用胶硫化特性、物理性能、耐热老化性能、耐油性能和动态力学性能的影响。结果表明:炭黑品种对ACM/ECO并用胶的焦烧时间和正硫化时间影响不大；随着炭黑粒径的增大、结构度降低，ACM/ECO并用胶的拉伸强度、拉断伸长率、撕裂强度、压缩永久变形和耐油性能均有不同程度的下降；炭黑粒径对ACM/ECO并用胶的耐热老化性能和玻璃化温度影响不大，炭黑粒径大的并用胶tanδ值较大。;The effects of carbon black type on the curing behavior,physical properties,heat aging resistance, oil resistance and dynamic properties of ACM/ECO blends were investigated.The result shows that, the type of carbon black had little influence on the scorch time and optimum cure time of ACM/ECO blends; as the particle size of carbon black increased and structure was lower,the tensile strength,elongation at break,tear strength,compression set and oil resistance of ACM/ECO blends were decreased;the particle size of carbon black had little effect on the heat aging resistance and glass transition temperature of ACM/ECO blends,but the tanδ values of blends loaded with big particle were higher
