Application of Phosphorus-Nitrogen Modified Graphene and Graphite-based Flame Retardant in Epoxy Resin

Abstract

环氧树脂(EP)作为一种重要的热固性聚合物材料,具有优异的耐化学腐蚀性能、机械性能、电绝缘性能和热导率经常被应用在涂料、粘合剂、电绝缘材料、复合材料及其他领域。然而,环氧树脂的可燃性及本质固有的脆性等缺点限制了它的应用。因此要提高其耐热性能和防火阻燃性能,以满足在各个领域的应用需求。环氧树脂型膨胀型钢结构防火涂料能够有效防止建筑倒塌并延长逃生时间,并且耐候、耐蚀性好,对海工装备和海上石油平台钢结构的防火具有重要意义。传统的膨胀型阻燃剂的高负载要求导致了涂料高密度、缺少韧性、机械性能和粘结性能较差、难以加工等缺点。所以,开发膨胀型阻燃剂系统的新型的协效剂来实现高效防火显得十分重要。另外,为拓展环...Epoxy resin (EP) is a kind of important thermosetting polymer material, which is often used in coatings, adhesives, electrical insulating materials, composite materials and other fields for its excellent chemical corrosion resistance, mechanical properties, electrical insulation, and thermal conductivity .
