摘要
以混合硅烷为原料,采用水解-缩聚工艺合成无溶剂单组分有机硅浸渍树脂,研究了不同Si-H、Si-Vi、Si-Ph摩尔含量、不同运动黏度对有机硅浸渍树脂固化性能的影响。结果表明,Si-H摩尔含量为3.2%、Si-Vi摩尔含量为7.9%、Si-Ph摩尔含量为45%,动力黏度为1300mPa·s时,有机硅浸渍树脂介电常数低,力学性能佳,热稳定性优异。
Abstract
Mixed silane was used as the raw material to prepare solvent-free one-component organosilicon impregnating resin by hydrolysis and polycondensation reaction.The effects of Si-H group,Si-Vi group and Si-Ph group molar content and kinematic viscosity on the properties of the resin were investigated.The results showed that:when the Si-H group molar content was 3.2%,Si-Vi group molar content was 7.9%,Si-Ph group molar content was 45% and the dynamic viscosity was 1300mPa·s,the resin shown the low dielectric constant,the best mechanical properties and the excellent thermal stability.
