Effects of graphene and dimethyl methylphosphonate on flame retardant properties of vinyl ester resins and glass fiber reinforced composites
摘要
Abstract
Vinyl ester resin and glass fiber reinforced composites were modified by graphene-dimethyl methylphosphonate(DMMP)compound flame retardant.The effects of the compound ratio of graphene and DMMP on the flame retardancy and thermal stability of vinyl ester resin and glass fiber reinforced composites were studied by vertical combustion(UL-94)test,limit oxygen index(LOI)test,thermogravimetric analysis(TGA)test and cone calorimetry test.Results indicated that the UL-94 test of 0.83％graphene-16.60％DMMP compound modified vinyl ester resin and glass fiber reinforced composites specimens could pass vertical burning fire rating V-0 grade.After adding 0.41％graphene-16.59％DMMP compound flame retardant,the heat release rate(HRR),total heat release(THR)and total smoke release(TSR)of resin specimens decreased by 34.3％,70％and 36.4％,respectively,compared with pure vinyl ester resin specimens.Similarly,the LOI of the composite specimen modified by 0.41％graphene-16.59％DMMP compound was 39.1％and the smoke density decreased,indicating that the graphene-DMMP compound system improved the flame retardant and smoke suppression properties of the specimens.The maximum thermal decomposition rate of the specimens increased after the combination of graphene and DMMP,the graphitization degree of the carbon layer increased after combustion,and the thermal stability of the specimen was enhanced.The analysis showed that the flame retardant mechanism of graphene-DMMP compound system was the combination of gas phase flame retardant and condensed phase flame retardant.关键词
