应用动态硫化技术制备三元乙丙橡胶(EPDM)/聚1-丁烯(PB)热塑性硫化胶(TPV),研究不同橡塑比TPV及其返炼TPV的性能。结果表明:随着EPDM/PB共混比的减小,TPV的邵尔A型硬度、拉伸强度、撕裂强度逐渐增大;当EPDM/PB共混比为60/40时,TPV的拉断伸长率最大,热氧老化性能较好;在试验范围内,EPDM/PB共混比为70/30时,返炼TPV的性能最好。 |
英文摘要: |
EPDM/Poly(1-butene)(PB) thermoplastic vulcanizate(TPV)was prepared by dynamic vulcanization.The properties of the TPV and reprocessed TPV with different blending ratio of rubber and plastic were investigated.The results showed that,with the decrease of EPDM/PB blending ratio,the Shore A hardness,tensile strength and tear strength of the TPV increased.When EPDM/PB blending ratio was 60/40,the elongation at break and thermo-oxidative aging property of the TPV were the best.Within the scope of the experiment,when EPDM/PB blending ratio was 70/30,the properties of reprocessed TPV was the best. |
