摘要:气相法制备的纳米二氧化硅是补强高温硫化硅橡胶的最好填料。研究了纳米二氧化硅的结构及分散性对硅橡胶结构及性能的影响。结果表明分散成100~200nm尺度的二氧化硅聚集体对硅橡胶具有良好的补强作用。未经表面改性的纳米二氧化硅,m(SiO2)∶m(生胶)=0.35~0.40时对硅橡胶的补强作用效果最佳。硅橡胶中加入纳米二氧化硅粉体,形成了以二氧化硅为晶核的微晶区,增加了物理交联点,更易发生结晶。
Silica nanoparticle synthesized by aerosol method was the best reinforcing filler for HTV silicone rubber. The influence of the structure of silica nanoparticles and their dispersion among the silicone rubber were investigated. The results show that the silica aggregates between the size of 100~200 nm have a better reinforcing function to the silicon rubber. The optimum reinforcement in silicon rubber is obtained when added with 35~40 g untreated silica nanoparticle per 100 g rubber. Microcrystlline region is formed by silica nucleus when added with silica nanoparticles in silicon rubber, which enhances the physical cross-linking and crystallization easily.
