摘　　要：采用分子复合改性三聚氰胺氰尿酸盐(M-MCA)与无机阻燃剂氢氧化铝、氢氧化镁复配阻燃含磷环氧树脂。通过UL94垂直燃烧(VB)、微型燃烧量热分析(MCC)、极限氧指数(LOI)等测试对阻燃材料的燃烧性能及行为进行了表征,同时采用热失重(TGA)分析方法对阻燃材料相应的降解历程和阻燃机理进行分析。结果表明,M-MCA与氢氧化铝(ATH)组合体系对含磷环氧树脂具有显著协同阻燃效果,而与氢氧化镁(MH)则表现出对抗效应,对上述协同及对抗阻燃机理进行了分析和讨论。Molecular composite modified melamine cyanurate(M-MCA)and inorganic flame retardant aluminum hydroxide,magnesium hydroxide compound were used to improve the flame retardancy of phosphorus-containing epoxy resin.The combustion performance and behavior of flame retardant materials were characterized by UL94 vertical burning test,micro-combustion calorimetry(MCC),limiting oxygen index and so on.And the corresponding degradation process and flame retardant mechanism of materials was analyzed by thermogravimetric analysis(TGA).The results show that the combination of M-MCA and aluminum hydroxide has a significant synergistic flame retardant effect on the phosphorus-containing epoxy resin,while it exhibits an antagonistic effect with magnesium hydroxide.The above synergistic and anti-flame retardant mechanism is analyzed and discussed.
