The properties of the film properties of NR including mechanical properties, heat aging resistance, infrared analysis and electron micrograph analysis were studied in situ. Silica particles could be grafted in situ to NR molecular chains with amount of 1.0%, and the tear strength could be up to 87.3721 Mpa, increased by 264.2%%研究原位生成对NR胶膜性能的影响.通过对力学性能、热老化性能、红外分析及电镜照片分析.得出原位反应可以在NR分子链中接枝二氧化硅粒子,并且在添加量为1.0％,撕裂强度为87.3721 MPa,提高了264.2％.
