MQ硅树脂增强加成型室温硫化硅橡胶

黄伟 黄英 赵洪涛 余云照

摘要:研究了MQ硅树脂对加成型室温硫化硅橡胶的增强作用。结果表明,含乙烯基的MQ硅树脂对加成型室温硫化硅橡胶的增强作用明显,硅橡胶的透明性很好。硅橡胶的强度随着MQ硅树脂中乙烯基含量的增加先增加而后下降。SiH/SiCH=CH2(摩尔比)为1.2~1.5时,硅橡胶具有较好的力学性能。

Abstract:The mechanical properties of room temperature vulcanizing silicone rubbers of additioncuring type were improved by the MQ silicone resins containing vinyl groups. The silicone rubbers reinforced by MQ silicone resins had high transparency. The tensile strength of the silicone rubbers increased first and then decreased with increasing vinyl groups in MQ resin. The silicone rubbers had higher mechanical properties when the mole ratio of SiH to SiCHCH2 was 1.21.5.
Keywords: MQ silicone resin; room temperature vulcanizing silicone rubber; reinforcement
