摘 要:研究了可发性聚苯乙烯预发泡的工艺,用脲醛树脂与聚磷酸铵、硼酸锌的混合物涂覆预发泡珠粒,使用模压发泡制得无卤阻燃聚苯乙烯泡沫塑料,对其原料配比进行了研究,当m(可发性聚苯乙烯):m(脲醛树脂):m(聚磷酸铵):m(硼酸锌)=100:(120~130):18:1时,聚苯乙烯泡沫塑料的阻燃性最好,成型加工容易,产品外观好。The pre-foaming technology of expandable polystyrene(EPS) was studied. Pre-foamed PS beads were coated by composite of urea-formaldehyde(UF) resin mixed with ammonium polyphosphate(APP) and zinc borate(ZB). The halogen-free flame retardant PS foaming plas- tics material was made by compression molding. The ratio of raw materials were studied, when m(ESP):m(UF resin):m(ZB) is equal to 100: (120130):18: 1, the flame retardant PS foa- ming plastics material is best and it is easy to molding processing, and has good appearance as well.
