摘要
本文研究了Ｓｂ－Ａ复合阻燃剂在软ＰＶＣ中的热稳定性、阻燃抑烟性及力学性能。结果表明，使用Ｓｂ－Ａ复合阻燃剂后，软ＰＶＣ的氧指数可达３０．８，同时发烟量只相当于使用超细Ｓｂ２Ｏ３时的７７％。Ｓｂ－Ａ复合阻燃剂与超细Ｓｂ２Ｏ３相比，有助于提高ＰＶＣ的热稳定性及抗张强度。
The heat stability,burning and mechanical behaviour of plasticized PVC after being treated with complex flame-retardant Sb-A were studied.It showed that the limiting oxygen index(LOI) of plasticized PVC was as high as 30.8,at the same time,the quantity of smoke was reduced to 77%.Compared with ultra fines of pure Sb 2O 3,Sb-A can improve the heat stability and tensile strength of plasticized PVC.
