摘要
以珍珠岩为填料制备了聚醚型硬质聚氨酯泡沫材料(RPUF),研究了珍珠岩的填充量,珍珠岩粒径对RPUF板材的机械性能及导热性能的影响,确定了最佳的填料比例,珍珠岩的最佳填充量可达40%。通过加入阻燃剂TCPP和DMMP等,提高了珍珠岩填充RPUF保温板的阻燃性能,材料的最佳氧指数可达到34.1。
Flame-retardant rigid polyurethane foam insulation board was prepared by using perlite as filler.The effects of filling coefficient and particle size of perlite on the composites properties,such as mechanical and thermal conductivity,were investigated.The best filling coefficient of perlite was 40%.To further improve the flame resistant performance of the composites,TCPP and DMMP were used as the additional flame retardants,and the best limiting oxygen index(LOI) was 34.1.
