氟橡胶双酚AF/BPP硫化体系硫化特性的研究

Effect of bisphenol AF/BPP vulcanization system on the vulcanization property of fluorine rubber

研究了双酚AF硫化体系中硫化剂双酚AF、促进剂BPP对氟橡胶硫化特性的影响以及硫化温度对硫化特性的影响。结果表明:硫化剂双酚AF的用量主要影响胶料的交联密度以及硫化时间,并且可以改善胶料的加工性能;促进剂BPP的用量主要影响胶料的硫化时间,对加工性能有一定的影响;硫化温度的提高会使交联密度下降。

In this article,we studied the effect of bisphenol AF,BPP on the vulcanization property of fluororuber and studied the effect of curing temperature on the Vulcanization property. The result showed that the dose of bisphenol AF can mainly affected the crosslinking density and the curing time and can improved the workability of fluororuber; The dose of accelerator BPP can mainly affect the curing time and can affected the workability more or less. Prolonging curing time may lower the crosslinking density.
