Preparation and properties of flame retardant epoxy resin/low molecular weight polyphenylene ether materials
摘要
Abstract
EP/PPO/BDP flame retardant composites were prepared by modifying epoxy resin/the low molecular weight polyphenylene(EP/PPO)with bis(diphenyl)phosphate(BDP).Through LCR bridge,TGA,UL-94,LOI,cone calorimetry and mechanical tests,the effects of liquid flame retardant BDP on dielectric properties,thermal degradation properties,flame retardancy and mechanical properties of EP/PPO composites were studied.The results showed that the dielectric constant of the composites decreased from 2.81 to 1.27(2M)when the loading of BDP was 10%.Although the initial degradation temperature of the composites decreased slightly,the char residue increased obviously at the high temperature.Only adding 5%BDP could make EP/PPO materials reached UL-94 V-0,which reduced the heat release rate,the smoke release and the toxic gas release of EP to a great extent.The fire hazard of EP composites was effectively reduced at the same time.The excellent mechanical properties of the EP/PPO composites were maintained,which indicated that the compatibility of the BDP and the EP/PPO composites was good.关键词
