摘　　要：采用二氧化硅粒子填充α,ω-双乙烯基聚二甲基硅氧烷,以含氢聚硅氧烷作为交联剂,在铂催化剂作用下制得加成型液体硅橡胶材料,对其流变性和分散性进行了研究,并比较了不同二氧化硅粒子填充加成型液体硅橡胶的显微结构与力学性能。The additional cured liquid silicone rubber （LSR） was prepared by α,ω- divinyl polydimeth- ylsiloxane filled with different kinds of SiO2 particles, using active hydrogen - containing polysiloxane as the cross -linking agent and platinum as the catalyst. The rheology and particle dispersion of polydimethylsiloxane was characterized. The microstructure and reinforce properties of the addition - cured liquid silicone rubber filled with different SiO2 particles were also discussed.
