新型难燃可发性聚苯乙烯的研制

Research and Production of New Type of Expanded Polystyrene

介绍了用芳香族溴化物M代替传统阻燃剂,生产新型难燃可发性聚苯乙烯。从阻燃剂的投加时间及投加量对产品的性能及阻燃效果的影响,进行了探讨研究,确定了投加时间为苯乙烯聚合转化率达85％、投加量为(1.0—1.5)％可达到较佳的阻燃效果。

How to use aromatic bromide M instdad of traditional fire retardant agent to produce new type of incombustibleexpanded polystyrene was introduced here. What effect did when and how much to charge fire retardant agent have on product, s performance and fire retardant result was explored and studied. Charge time was chosen when the styrene polymerization con-version was 85 % and the amount to be charged was 1.0 to 1. 5 % .
