【摘要】 硅橡胶作为特种橡胶体系的一个重要成员，以其耐高温、耐寒、耐候及电气特性等优良品质得到国防、航天航空、电子、医疗卫生等行业的青睐［１］。然而，目前工业上主要采用价格昂贵的气相白炭黑作硅橡胶的增强剂，使硅橡胶制品成本偏高，限制了硅橡胶的普及应用，阻碍了硅...更多还原

【Abstract】 In order to enhance the applied values of minerals and reduce the cost of silicone rubber products, silicone rubber reinforcing filler were prepared by ultrafinerashing and surface chemical modifying. The influence of the kind of minerals, the surface area of powders and coupling agent on reinforcing effect is discussed. As a result,the reinforcing effects of modified ultrafine mineral powders are close to that of fumed silica.更多还原
