HCCPx/OvPOSS1％/TEP10％/PMMA复合材料的制备与性能研究
Preparation and Performance Study of HCCPx/OvPOSS1％/TEP10％/PMMA Composites
摘要
Abstract
Polymethyl methacrylate(PMMA)composites were prepared by physical blending of hexachloro-cyclotriphosphonitrile(HCCP),octavinyl sesquisiloxane(OvPOSS),and triethyl phosphate(TEP).The effect of HCCP on the thermal stability and flame retardancy of OvPOSS1％/PMMA composite system was investigated.The study found that the six-membered ring structure of-N=P in HCCP and the elements N,P,and Cl can work in synergy with the Si-O octahedral structure and the Si element in OvPOSS to hinder the movement and thermal decomposition of the PMMA molecular chains.The temperatures at which the PMMA composite loses 5％and 50％of its weight were 196.6℃ and 381.3℃,respectively,the glass transition temperature was 174℃,and the carbon residue rate of PMMA composite was 15.75％when the mass fraction of HCCP was 20％,reaching UL 94 V-1 flame retardancy.It could effectively alleviate the problem of poor interface compatibility when added 10％TEP in OvPOSS1％/PMMA composite system.However,TEP would have a nucleophilic substitution reaction with HCCP,resulting in a significant decrease in the transparency of the composite system.关键词
