含溴化合物对丙烯酸酯共聚物阻燃耐热性的影响

Bromine compounds' influence on flame-retardance and thermal endurance of polyacrylates

氧指数 (LOI)测定、热重法 (TG)、傅立叶红外光谱热跟踪 (FT -IR)研究等方法研究各种含溴化合物对聚丙烯酸酯阻燃耐热性影响的实验结果表明 ,这些含溴化合物能较好地阻燃聚丙烯酸酯 ,并且用量越多阻燃作用越强 .溴锑协同作用可以提高聚合物的阻燃效果 ,四溴醚由于含有双键参与聚合反应 ,因此阻燃效果最好 .

Effects of some bromine compounds on the flame-retardance and thermal endurance of polyacrylates have studied by limiting oxygen index determination?thermogram method?Infra-red spetrum.The results show that bromine compound can flame-retard polyacrylates well and the flame-retardance is increased with bromine increasing.Bromine-Antimony flame-retardant synergistic reaction can improve flame-retardance of polyacrylates Tetra bromine ether can copolymerize with acrylate,and make polymers become carbon while they are pyrolysised,so it possesses the best flame-retardant effect.
