%X 采用动态硫化法制备乙烯-醋酸乙烯酯共聚物(EVA)/氯化聚乙烯(CPE)/丁腈橡胶(NBR)共混型热塑性硫化胶(TPV)，研究TPV的应力-应变行为、微观相结构、Payne和Mullins效应。结果表明：甲基丙烯酸锌（ZDMA）补强TPV的储能模量随应变的增大而显著下降，表现出典型的Payne效应；TPV存在明显的Mullins效应，相同拉伸比下，与EVA/CPE/NBR TPV相比，ZDMA补强TPV的最大应力、瞬时残余应变、内耗、损耗因子和软化因子均有所提高。;Thermoplastic vulcanizate(TPV) of ethylene-vinyl acetate copolymer(EVA)/chlorinated polyethylene(CPE)/nitrile butadiene rubber(NBR) was prepared by dynamic vulcanization,and the stress-strain behavior,microstructure,Payne effect and Mullins effect of the obtained TPV were investigated.The zinc dimethacrylate (ZDMA) reinforced TPV showed a typical Payne effect: the storage modulus decreased obviously with the increase of strain amplitude.The ZDMA reinforced TPV also showed a strong Mullins effect.Under the same extension ratio,compared with those of unreinforced TPV,the maximum stress,instantaneous residual strain,internal loss,loss factor and softening factor of ZDMA reinforced TPV were higher
