以乙烯基硅油为原料，含乙烯基三乙氧基硅烷（ A-151）就地处理过的气相法白炭黑为填料，制得高硬度、高强度加成型液体硅橡胶。研究了A-151的用量对加成型液体硅橡胶性能的影响。结果表明， A-151的用量能显著影响硅橡胶的硫化特性，随着A-151用量的增加，硅橡胶胶料的焦烧时间逐渐缩短，而正硫化时间则逐渐延长；硅橡胶的拉伸强度、撕裂强度、电气强度等先增后降，拉断伸长率降低、邵尔A硬度上升，胶料的起始黏度和黏度增长率上升，对硅橡胶的体积电阻率影响不大。当A-151的用量为1份时，硅橡胶的拉伸强度达最大值（8.8 MPa）、撕裂强度为22.2 kN/m、邵尔A硬度为50度、拉断伸长率为370％、电气强度为22.5 kV/mm、体积电阻率为13.5×105Ω· cm，对硅橡胶的黏度和黏度增长率影响较小。

Molding liquid silicone rubber with high hardness and strength was prepared using vinyl sili -cone oil as the raw material , fumed silica treated by vinyltriethoxysilane as the filler .The influence of the vi-nyltriethoxysilane on the performance of the molding liquid silicone rubber was studied .Results show that the content of vinyltriethoxysilane can significantly affect the vulcanization characteristics of the silicone rubber . With the increase of the amount of vinyltriethoxysilane , the scorch time of the silicone rubber gradually short-ens, while the curing time gradually extended , and the tensile strength , tear strength, and electrical strength of vulcanized silicone rubber reach to a maximum and then decrease .There is no significant effect on the vol-ume resistivity of the silicone rubber when the tensile elongation decreases , but the Shore A hardness and ini-tial viscosity rate increases .With the loadings of vinyltriethoxysilane at 1 phr, the tensile strength of the sili-cone rubber reaches to the maximum value (8.8 MPa) with a tear strength of 22.2 kN/m, a Share A hardness of 50, a tensile elongation of 370%, an electric strength of 22.5 kV/mm, and a volume resistivity of 13.5105 cm, with no significant effect on the viscosity and its growth rate .
