摘要
研究了苯基硅橡胶的流动性及其影响因素。研究结果表明,在低苯基含量时,苯基的存在使甲基硅橡胶的结晶性下降,且苯基含量越高,结晶性越低;随摩尔质量、苯基含量的上升,苯基硅橡胶的粘度也相应增高,但并非均匀变化;苯基硅橡胶的粘度随温度的升高而下降,而高摩尔质量的苯基硅橡胶对温度的依赖性更大。剪切作用对苯基硅橡胶粘度、流动性的影响明显。
The mobility and factots affecting mobility of phenyl silicone rubber were studied in this paper.The result showed that the crystallinity of phenyl silicone rubber was declined because of the presence of phenyl and the higher the phenyl content,the lower the crystallinity when the phenyl content was low.The viscosity of the phenyl silicone rubber were rised as molar mass and phenyl content of the rubber were increased but the changes was not uniform.The viscosity of the phenyl silicone rubber was declined as temperature were increased and temperature dependence of the high molar mass phenyl silicone rubber was larger.The influence of shearing on the viscosity and mobility of the phenyl silicone rubber were evident.
