摘　　要：研究了胶粉/SEBS-g-MA共混比对胶粉/SEBS-g-MA复合材料力学性能和粘弹行为的影响。结果表明:当共混比为60/40时,复合材料的力学性能最佳;随着胶粉用量的增加,应力松弛程度增大,随着热处理温度的升高,应力松弛可逆恢复程度先减小后增大;Mullins效应随着温度的升高逐渐减弱。The effects of rubber powder/SEBS-g-MA blending ratio on mechanical properties and viscoelastic behavior of rubber powder/SEBS-g-MA composites were studied.The results showed that the composite had the best mechanical properties under 60/40 blending ratio.With the increase of the amount of rubber powder,the degree of stress relaxation increased.Furthermore,with the increase of heat treatment temperature,the degree of reversible recovery of stress relaxation first decreased and then increased.Meanwhile,the mullins effect gradually decreased with the increase of temperature.
