为了改变热塑性聚苯乙烯保温板的燃烧本质,采用特殊阻燃剂,即热固性酚醛树脂/Al(OH)3阻燃液对聚苯乙烯颗粒进行阻燃包覆.通过对主要制备工艺的优化研究,成功制得热固性聚苯乙烯泡沫保温板,并解决了保温板阻燃和保温相互制约的难题.结果表明:包覆改性后的聚苯乙烯板遇火燃烧时不产生熔融收缩现象,表面只是发生炭化,板材各项性能均满足标准要求,保温板燃烧性能可达B1级,热值为20.3 MJ/kg,保温系数小于0.036 0 W/(m·K).

The thermosetting phenolic resin/Al(OH)3 was used as a flame retardant coating to coat polyphenyl granule in order to change the combustion performance of polystyrene plates.By the research of the main preparation process, a kind of thermosetting polystyrene insulation foam board was made, and the problem between flame retardant and insulation was solved. The test results showed that it would not melt or shrink when the coated polystyrene plates were burning and it carbonized on the surface merely.All the performance indicators meet to the product standards. The combustion of insulation board could reach B1grade,which heat value was 20.3 MJ/kg , heat conductivity was less than 0.036 W/(m·k).
