| 摘 要： | 采用动态硫化法制备BR/乙烯-乙酸乙烯酯共聚物(EVA)热塑性硫化胶(TPV),并对其性能进行研究.结果表明:当BR/EVA共混比大于50/50时,TPV呈现出典型弹性体的应力-应变行为；当BR/EVA共混比为50/50～65/35时,TPV的硬度较低,综合物理性能良好；当BR/EVA共混比为60/40时,微米级的BR粒状物均匀分散在EVA基体中,两相界面结合良好.

| Abstract: | Thermoplastic vulcanizate(TPV) using BR and ethylene vinyl acetate copolymer(EVA) was prepared by dynamic vulcanization,and its properties were investigated.The results showed that when the blending ratio of BR/EVA was higher than 50/50,the TPV showed typical stress-strain behavior of an elastomer.When the blending ratio of BR/EVA was from 50/50 to 65/35,the Shore A hardness of TPV was low,and the comprehensive physical properties were good.When the blending ratio of BR/EVA was at 60/40,the particle-like BR... |
