以多种甲基和苯基有机硅单体为原料,采用水解缩聚的方法合成了有机硅树脂,研究了水用量、水解温度及固化体系对树脂性能的影响。结果表明,由该工艺合成的弹性体树脂加入烯丙基三乙氧基硅烷后可室温固化,同时具有较高的强度、较好的柔韧性、与金属及复合材料基材有较好的结合力及耐高温等优异的综合性能。
A variety of methyl and phenyl silicone monomer as raw materials, the use of hydrolytic polycondensation method of synthesis of silicone resin, water consumption, hydrolysis temperature and curing system on the resin performance. The results show that the elastomer resin synthesized by this process can be cured at room temperature after the addition of allyl triethoxysilane. At the same time, it has higher strength, better flexibility and better combination with metal and composite substrate Power and high temperature and other excellent performance.
