摘要
采用有机硅烷偶联剂处理CaCO3/SiO2复合粒子。改性后复合粒子在石蜡油和硅油中的分散情况得到改善。SEM图谱显示改性后的碳酸钙复合粒子在橡胶中较均匀分散。拉伸实验结果是碳酸钙复合粒子填充的RTV硅橡胶拉伸强度是填充脂肪酸处理的碳酸钙2倍多,碳酸钙复合粒子具有较好的补强作用。
Treated CaCO3/SiO2 by silane couple agents had good dispersion in petrolatum and silicon oil. SEM graph showed treated CaCO3/SiO2 equably dispersed in silicone rubber. CaCO3/SiO2 was well reinforcing filler. Tensile strength of silicone rubber filled by this particle was as double times as filled those treated by fatty acid.
