摘　　要：本文研究了胶料预处理的不同方式对硅橡胶补强的影响。结果表明:无论含羟基硅油与否,170℃预处理硅橡胶的拉伸强度最高,放置处理试样的拉伸强度介于未处理和170℃预处理之间;胶料预处理与否对不含羟基硅油的硅橡胶硬度没有影响。含羟基硅油的硅橡胶中,170℃预处理的试样硬度最低,未处理的试样硬度最高。含羟基硅油的硅橡胶断裂伸长率变化不大。不含羟基硅油的硅橡胶断裂伸长率为170℃预处理的试样最低。The effect of different methods of rubber pretreatment on reinforcement of silicone rubber researched in this paper. The results showed that： Regardless of whether or not containing hydroxy silicone oil, the tensile strength of silicone rubber under the 170~ pretreatment is the highest, the tensile strength of the sample with the placed treatment between the untreated samples and the 170℃ pre-treatment ones; pretreatment rubber is on the non- hydroxy The silicone oil did not affect the hardness of silicone rubber. The silicone rubber with hydroxy silicone oil, the hardness of silicone rubber under the 170℃pretreatment is minimum, the hardness of untreated sample is the highest, hydroxy silicone oil with the silicone rubber does not change the elongation at break Great. Hydroxy silicone oil-free silicone rubber elongation at break of 170℃ for a minimum of sample pretreatment.
