摘要
研究了不同并用比的氟橡胶(FKM)和丙烯酸酯橡胶(ACM)并用胶的硫变特性、物理机械性能、耐老化性、热稳定性和压缩永久变形性能。实验结果表明:ACM与FKM可以很好地混合并且各自交联,从而制备综合性能优异的并用胶;并用比为30/70的ACM/FKM并用胶综合性能较佳,二段硫化后其物理机械性能和压缩永久变形性能明显改善,且耐热空气老化性能优异;热重分析结果表明,并用胶有很好的热稳定性。
The cure characteristics, mechanical properties, resistance to heat and aging and compression set properties of ACM,FKM and their blends of varying compositions were studied. The experimental results showed that： ACM/FKM rubber blends were prepared by blending and crosslinking of two components respectively;The rubber blends showed optimized properties at the ACM/FKM mass ratios of 30/70, postcuring improved the strength properties and compression set of the system,none of the properties changed significantly during aging of the blends. Thermal gravity analysis indicated that the 30/70 ACM / FKM has good thermal stability.
