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。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 50 phr,the comprehensive properties of ACM/PET TPV was the best.
