摘要：
采用熔融共混法制备高抗冲聚苯乙烯(hips)/磷酸锆(ozrp)阻燃材料。利用热重分析(tga)研究其热稳定性和成炭量。利用微燃烧量热分析(mcc)和锥形量热仪测试(cct)测试其阻燃性能。结果表明:磷酸盐的加入,使得阻燃体系的成炭量有所增加,并且hips的热释放速率(hrr)和热释放容量(hrc)均有降低,相比纯hips,添加磷酸盐的hips材料热释放速度(hrr)上升较慢,这一结论与mcc、tga的结果一致。可以看出,层状磷酸锆的加入,可显著改善hips基体的阻燃性能,降低其火灾危险性。

abstract: high impact polystyrene (hips)/organophilic alpha-zirconium phosphate (ozrp) composites have been prepared through melting interaction. thermogravimetric analysis (tga) has revealed that hips/ozrp composites have charred residues increased in quantity compared with pure hips. micro-scale combustion calorimetric analysis (mcc) has indicated that the heat release rate (hrr) and heat release capacity (hrc) of hips decrease remarkably after phosphate is added. the cone calorimeter test (cct) has shown that the hrr of hips/ozrp composites rises slowly compared with that of pure hips, as the phosphate has promoted the formation of charred residues. this conclusion is identical with the mcc and tga results. all the experiments have demonstrated that the addition of layered zirconium phosphate can improve the flame retardancy of hips as largely as to prevent fire hazards.
