新型单组份磷-氮膨胀型阻燃剂的热分解动力学

摘要

T he thermal decomposition kinetics of the novel monomolecular P-N intumescent flame retardant hexalis-(4-DOPO-hydroxymethyl-phenoxy )-cyclotriphosphazene (DOPOM PC ) were studied by TG-DTG techniques at different heating rates in streams of N2 and air .The ki-netic parameters ,including the activation energy and frequency factor of the decomposition process for the DOPOMPC were calculated by the Kissinger and Flynn-Wall-Ozawa(FWO) methods .%利用热重分析法研究了在不同升温速率下新型单组份磷-氮膨胀型阻燃剂六（4-（9，10-二氢-9-氧杂-10-磷杂菲-10-氧化物）-羟甲基苯氧基）环三磷腈（DOPOMPC）在氮气气氛和空气气氛中的热分解动力学。采用Kis-singer和Flynn-Wall-Ozawa（FWO）法分别计算出DOPOMPC在相应气氛下的活化能和指前因子。
