摘　　要：简单介绍了纳米SiO2的表面化学性质及其粒子的聚集状态;归纳了物理吸附作用、氢键作用方式及共价键结合方式等基本的纳米SiO2与硅橡胶的作用方式;以纳米SiO2-纳米SiO2、纳米SiO2-硅橡胶的不同作用为基础列举了键合胶、复合团聚体及互穿网络模型等几种补强模型,并总结了其在补强过程中发挥的作用,从而对其补强机理研究进展进行更为详细的概括和介绍。The state of aggregation and chemical properties on the surface of nano-SiOz are introduced and the different modes of physical adsorption and action of hydrogen bond and covalent bond between nano-SiO2 and silicon rubber are summarized. Based on different modes of action in nano SiO2-nano SiO2 and nano SiO2-silicone rubber, se- veral reinforcement models such as bond adhesive model, composite aggregate model and interpenetrating network model are listed and these reinforcement models important impact on the reinforcement process are reviewed, so as to of- fer more detailed summarization and introduction of advance in reinforcement mechanism.
