【摘要】 以二乙醇胺和丙烯酸甲酯为原料合成AB2型单体,再和三羟甲基丙烷在对甲苯磺酸催化下得到端羟基超支化一代产物(HPAE1),最后用五氧化二磷和磷酸作磷酸化剂,将HPAE1磷酸化后获得新型膨胀型阻燃剂HPAE1-P.通过FTIR、元素分析、1HNMR等对HPAE1-P的分子结构进行了表征,并通过TGA考察了其热稳定性.结果表明:HPAE1的主要C骨架没有变化,羟基部分被磷酸化;热稳定性良好.应用试验表明:织物经该阻燃剂整理后,阻燃性能大幅提高,LOI可达30.5%,阻燃等级为B1级.更多还原

【Abstract】 The hyperbranched product(HPAE1) with terminated hydroxyl was prepared based on trimethylolpropane and AB2 monomer synthesized by methyl acrylate and diethanolamine using p-toluene sulfonic acid as catalyst.Finally,a novel intumescent flame retardant HPAE1-P was synthesized using HPAE1 and phosphorylation agent(phosphorus pentoxide and phosphoric acid) via partial phosphorylation reactions.The molecular structure and thermal stability of the HPAE1-P were characterized by FTIR,elemental analysis,1H NMR and TGA.The results showed that the main C skeleton of HPAE1 did not change,and hydroxyl was partially phosphorylated.The flame retardant had good thermal stability.The application tests showed that flame retardant performance of the finished fabric increased,LOI could reach 30.5%,flame retardant grade reached the B1 level.更多还原
