摘　　要：采用正硅酸四乙酯为二氧化硅前驱体,纳米二氧化硅前驱体反相微乳液与溶聚丁苯橡胶原胶溶液共混原位反应生成纳米二氧化硅,使二氧化硅微粒均匀分散在溶聚丁苯橡胶原胶液中,形成二氧化硅纳米级分散的溶聚丁苯橡胶溶液,最后经过汽提干燥工艺,得到二氧化硅纳米级分散的丁苯橡胶/纳米二氧化硅绿色轮胎母炼胶.对制备出的复合材料进行X射线衍射、扫描电子显微镜等测试分析,发现制备出的二氧化硅的平均粒径为40.4nm.同时,制备出的二氧化硅被丁苯橡胶很好地包裹在内,均匀地分散在丁苯橡胶内.Silica/styrene butadiene rubber nanocomposites were prepared using the tetraethyl orthosili- cate as raw material and the cetrimonium bromide and butyl alcohol as surfactants. The nanosized silica was prepared by a reverse micro-emulsion method. The composite solution of nanosized silica-styrene butadiene rubber was obtained by mixing the nanosized silica precursor with styrene butadiene rubber solution. The nanosized silica-styrene butadiene rubber composite material was finally obtained by the way of the annular stripping. The composite material was characterized by X-ray diffraction, fourier transform infrared and scanning electron microscopy. The results show that the size of silica particles is about 40.4 nm; meanwhile,silica is surrounded by styrene butadiene rubber.
