本文选用溴系阻燃剂 ,Sb2 O3,配合自由基引发剂 ,成炭剂构成阻燃体系用于PS ,研究其阻燃性能。实验结果表明 ,自由基引发剂的加入可大大减少溴化物的用量 ,降低成本 ,又可改善材料的透明性 ;

s Bromic flame retardant,Sb 2O 3,as well as free radical initiator and carburant,were used to prepare a flame retardant system for PS,and the flame retardance was studied.The experiment results showed that the addition of free radical initiator sharply reduced the content of bromine and cost,the transparence was improved as well.While the addition of carburant had good effect on the flame retardance and lessened drippage.
