改性异佛尔酮二胺固化剂的制备与固化性能研究
Preparation and curing properties of modified isophorone diamine curing agents
摘要
Abstract
Epoxy resin is a widely used thermosetting resin,and curing agent accounts for a large proportion of the epoxy resin system.We modified the curing agent isophorone diamine(IPDA)with epoxy resin by adjusting their ratios,to obtain modified curing agents with different properties;then we reacted the modified curing agents with epoxy resin to prepare different cured samples.Finally,we used the Gelprof 518 resin behavior analyzer to analyze and evaluate the curing process and cured samples.The performance of the modified curing agents is improved compared to the unmodified curing agent,but there are differences in performance,and the reactivity is the highest when m(NPEL-128)∶m(IPDA)∶m(benzyl alcohol)=9∶46∶45.This study reveals the effect of ratios of curing agents on the curing of epoxy resin,and provides ideas for the modification of curing agents in industrial processes.关键词
