焦磷酸哌嗪@COF阻燃剂的制备及其对环氧树脂的阻燃作用
Preparation of piperazine pyrophosphate@COF flame retardant and its flame retardant effect on epoxy resin
摘要
Abstract
A covalent organic framework(COF)was prepared by solution synthesis,and then the COF was coated on pi-perazine pyrophosphate(PAPP)to form PAPP@COF hybrid flame retardant,which was applied to epoxy resin(EP).The effects of PAPP@COF hybrid flame retardants on the flame retardancy and smoke suppression of EP were analyzed by oxygen index meter,vertical combustion meter and cone calorimeter.The results indicated that the oxygen index of EP composite can reach 30.0%,the peak heat release rate was 911.35 kW/m2,and the peak smoke release rate was 0.394 m2/s,which were 37.36%and 34.27%lower than that of pure EP by adding 2 phr PAPP@COF.PAPP@COF hybrid flame retardants have excellent flame retardancy and smoke suppression effects on EP,which pro-vides a certain basis for the research of COF flame retardants.关键词
