【摘要】 采用动态硫化法制备丙烯酸酯橡胶(ACM)/聚对苯二甲酸乙二醇酯(PET)热塑性硫化胶(TPV),并研究硅土、炭黑和白炭黑对TPV物理性能、流变性能和耐油性能的影响。结果表明:与硅土和炭黑相比,白炭黑对ACM/PET TPV的补强效果较好;白炭黑的填料网络结构使TPV的表观粘度明显增大;白炭黑的加入能够提高TPV的物理性能和耐油性能,当白炭黑用量为50份时,所制得的ACM/PET TPV综合性能最佳。更多还原

【Abstract】 The acrylate rubber(ACM)/polyethylene terephthalate(PET)thermoplastic vulcanizate(TPV)was prepared by dynamic vulcanization method,and the influence of different reinforcing agents(siliceous earth,carbon black and silica)on the physical properties,rheological property and oil resistance of ACM/PET TPV was investigated.The results showed that,compared with siliceous earth and carbon black,silica was more effective in the reinforcement of ACM/PET TPV.By adding silica,the apparent viscosity of ACM/PET TPV increased,and the physical properties and oil resistance of ACM/PET TPV were significantly improved.When the addition level of silica was 50phr,the comprehensive properties of ACM/PET TPV was the best.更多还原
