氟橡胶双酚AF/BPP硫化体系的研究

Research on Bisphenol AF/BPP Cure System of Fluorine Rubber

研究了硫化剂双酚AF、促进剂BPP用量及硫化温度对氟橡胶硫化特性的影响。结果表明:双酚AF和BPP的用量主要影响胶料的交联密度及硫化时间,并对加工性能有一定的影响;硫化温度的提高会缩短焦烧时间和正硫化时间,但有使交联密度下降的趋势。

The effect of the levels of bisphenol AF and BPP and the cure temperature on the cure characteristic of fluorine rubber was investigated. The results showed that the levels of bisphenol AF and BPP mainly influenced the crosslink density and cure time, and processibility as well. With the increasing of cure temperature, the scorch time and optimum cure time decreased, but the crosslink density had a tread of decreasing.
