中文摘要: |
采用添加短纤维的不饱和聚酯(DMC)填充EPDM/甲基乙烯基硅橡胶(MVQ)并用胶,研究其物理性能和耐热老化性能。结果表明,添加DMC后,EPDM/MVQ并用胶的邵尔A型硬度和拉伸强度大幅提高,耐热老化性能较好,兼具EPDM,MVQ和DMC的优点。EPDM/MVQ并用胶的较优配方为:EPDM 25,MVQ 75,DMC 80,白炭黑 40,氧化锌 5,防老剂D 1,硫化剂DCP 6,促进剂DM 0.8。 |
英文摘要: |
A DMC(a short fibre/unsaturated polyester composite)-reinforced EPDM/MVQ blend was prepared and its physical properties and aging properties were investigated.The results showed that the DMC-reinforced EPDM/MVQ blend combined the advantages of EPDM/MVQ with those of DMC,and possessed much higher Shore A hardness and tensile strength,and better thermal aging properties.The optimized formula of DMC-reinforced EPDM/MVQ blend was as follows:EPDM 25,MVQ 75,DMC 80,silica 40,ZnO 5,antioxidantD 1,curing agent DCP 6,accelerator DM 0.8. |
