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。 Reinforcement

Yunzhao Abstract:The mechanical properties of
room temperature vulcanizing silicone rubbers of addition- curing 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 SiCH=CH2
was 1.2~ 1.5. 作者简介:黄伟,博士。 参 考 文 献 1,黄伟,黄英,余云照.MQ硅树脂增强缩合型室温硫化硅橡胶[J].合成橡胶工业,1999,22(5):281 收稿日期:1999-05-31;修订日期:1999-12-20。 |
