High-transparency flame-retardant PS coiled material

The invention relates to the technical field of polystyrene materials, in particular to a high-transparency flame-retardant PS coiled material. According to the method, the calcium-based whiskers are pretreated by the phosphate coupling agent, and the phosphoric acid long-chain alkyl ester is added into the system, so that the polyphosphoric acid flame retardant can be more uniformly distributed in the system, and meanwhile, the influence of the flame retardant on the calcium sulfate whiskers and other calcium-based whiskers is reduced; the invention further provides the polystyrene coiled material with transparency, flame retardant property and mechanical strength. 本申请涉及聚苯乙烯材料的技术领域，尤其是涉及一种高透明度阻燃PS卷材。本社情中通过将钙基晶须进行磷酸酯偶联剂预处理，并在体系中添加磷酸长链烷基酯，使聚磷酸阻燃剂在体系中可以更加均匀地分布，同时减少阻燃剂对硫酸钙晶须和其他钙基晶须的影响，进而提供了一种兼顾透明度、阻燃性能和机械强度的聚苯乙烯卷材。
