摘要
文章介绍了阻燃剂的阻燃作用及其分类,并综述了各种常用阻燃剂的阻燃机理。研究了稀土改性氢氧化镁(Mg(OH)2)、氢氧化铝(Al(OH)3)、三氧化二锑(Sb2O3)、硼酸锌(2ZnO·3B2O3·3.5H2O(ZB))、改性红磷为主的复合阻燃体系对糊状PVC阻燃性能的影响。通过氧指数测定仪对样品的氧指数测定,根据单因素分析寻找出复合无机阻燃剂的最佳配方。
The flame retardation mechanism and the classification was reviewed in the paper. The effect of rare earth modified magnesium hydroxide (Mg(OH)2), aluminum hydroxide (Al(OH)3), antimony trioxide (Sb2O3), zinc borate (2ZnO3B203-3.5H20(ZB)) on poly (vinyl chloride) (PVC) was discussed. Through the analysis of the factors influencing oxygen index measurement of flame retardant PVC, the optimal ratio of inorganic flame retardant compound was determined.
