Chopped basalt fibre (BF)-reinforced silicone rubber/fluorine rubber composites were investigated to improve their mechanical and thermal properties, in which the blend of silicone rubber (MVQ) and fluorine rubber (FKM) was used as a matrix of the composites, the BF was used as a reinforcement, and the coupling agents of KH550 (3-amino propyltriethoxysilane), KH590 (3-mercaptopropyl trimethoxysilane) and Si69 (bis(3-triethoxysilylpropyl) tetrasulfane) were used as the compatibiliser. The effect of length and content of the BF, and the type of coupling agent on the mechanical properties of composites were discussed. The results confirm that the mechanical and thermal properties of the KH590-BF/MVQ/FKM composites were optimal when the BF was 7 phr (parts per hundred rubber) with a length of 12 mm, and treated with coupling agent KH590 of 2.0 phr. Further compatibility between the BF and MVQ/FKM was optimum. The glass transition temperature (Tg) reduced from − 19.2 °C to − 28.0 °C, while the application range of KH590-BF/MVQ/FKM composites was widened.

研究了短切玄武岩纤维（BF）增强的硅橡胶/氟橡胶复合材料的机械性能和热性能，其中将硅橡胶（MVQ）和氟橡胶（FKM）的混合物用作复合材料的基质， BF被用作增强材料，KH550（3-氨基丙基三乙氧基硅烷），KH590（3-巯基丙基三甲氧基硅烷）和Si69（双（3-三乙氧基甲硅烷基丙基）四硫烷）的偶联剂被用作增容剂。讨论了高炉的长度和含量以及偶联剂的种类对复合材料力学性能的影响。结果证实，当BF为7 phr（每百份橡胶的份数），长度为12 mm并用2.0 phr的偶联剂KH590处理时，KH590-BF / MVQ / FKM复合材料的机械和热性能最佳。BF和MVQ / FKM之间的进一步兼容性是最佳的。玻璃化转变温度（Tg）从-19.2°C降低到-28.0°C，同时扩大了KH590-BF / MVQ / FKM复合材料的应用范围。
