摘要

硅橡胶和氟橡胶作为国防、航天等重要领域的耐热材料一直被人们青睐，但其有着各自地优缺点且价格昂贵，本文尝试将这两种橡胶制成并用胶以解决氟橡胶不耐低温和加工性差的问题，以期增大其使用温度范围。采用机械共混法制备硅橡胶/氟橡胶并用胶，研究了硅橡胶和氟橡胶的混炼工艺、并用比、共硫化体系和硫化条件对并用胶力学性能的影响。结果表明，当硅橡胶/氟橡胶的质量比为10：90，共硫化体系为3

硫化剂/过氧化二异丙苯（DCP），一段硫化温度为170℃、硫化压力为10MPa、硫化时间为30min，二段硫化温度为200℃、硫化时间为6h时，并用胶的力学性能达到最好。

Abstract

Silicone rubber (MVQ) and fluorine rubber (FKM) as a defense aerospace and other important areas of heat-resistant materials have been favored

but they have their own advantages and disadvantages and the both kind of rubbers are expensive. In this work

we try to prepare MVQ/FKM blends to solve the fluorine rubber intolerant low temperature and poor processing problems with a view to increasing its use temperature range. MVQ/FKM blends were prepared by mechanical blending. The mixing process

ratio

vulcanization system and curing conditions of silicone rubber/fluorine rubber were studied with the mechanical properties. The results show that the mechanical properties of the blends are the best when the blend ratio of silicone rubber/fluorine rubber is 10:90

the vulcanization system is 3

curing agent/dicumyl peroxide (DCP)

the first curing conditions are at 170℃ under 10MPa for 30min

and past curing conditions are at 200℃ for 6 hours.
