以六甲基二硅氧烷、双乙烯基四甲基二硅氧烷和硅酸乙酯为主要原料,合成加成反应型单体。红外和电子透镜分析结果表明,该单体中含有乙烯基、羟基和[SiO1/2]等基本结构,单体中的[SiO2]单元以2～10nm的聚集体形式存在。随该纳米单体的加入,硅橡胶拉伸强度提高为增强前的7～8倍,击穿强度增高4kV·(mm)-1左右;相对介电常数增大,介质损耗也相应发生变化。 With hexamethyldisiloxane, bis-vinyltetramethyldisiloxane and ethyl silicate as the main raw materials, the reaction of the synthesis of monomers. Infrared and electron lens analysis results show that the monomer contains vinyl, hydroxyl and [SiO1 / 2] and other basic structure, the monomer [SiO2] unit exists as 2 ~ 10nm aggregates form. With the addition of nano-monomer, the tensile strength of silicone rubber increased from 7 to 8 times before the increase, the breakdown strength increased about 4kV · (mm) -1; relative dielectric constant increases, the dielectric loss changes accordingly.
