摘　　要：采用玄武岩短纤维补强硅橡胶,研究玄武岩短纤维/硅橡胶复合材料的性能。结果表明:用丙酮脱玄武岩短纤维表面的浆膜,处理时间为50 min时效果最佳;用偶联剂KH-550对玄武岩短纤维表面进行处理,且玄武岩短纤维用量为20份时,玄武岩短纤维/硅橡胶复合材料的综合性能最佳;制备玄武岩短纤维/硅橡胶复合材料的最佳硫化条件为175℃/10 MPa×25 min。In this study, silicone rubber was reinforced by basalt short fiber, and the properties of basalt short fiber/silicone composite were investigated. Firstly, the basalt short fiber was treated with acetone to remove the surface covering, and the best result was obtained when the treatment time was 50 minutes. Then the short fiber was further treated by silane coupling agent KH-550. When the addi- tion level of KH-550 treated fiber was 20 phr,the comprehensive properties of the composite were the best. The optimum curing condition was 175 ℃/10 MPa× 25 min.
