摘　　要：将钠基蒙脱土(Na^+-MMT)有机化改性,制成有机蒙脱土(OMMT),采用熔融插层法分别制备HIPS/OMMT复合材料和聚磷酸铵(APP)体系阻燃的HIPS/OMMT复合材料。结果表明,HIPS/OMMT复合材料具有一定的阻燃性能,但阻燃性能的提高比较有限;与仅添加OMMT时相比,APP体系阻燃的HIPS/OMMT复合材料的阻燃性和抑烟性均得到进一步提高,以APP、季戊四醇(PER)和硼酸锌(ZB)为膨胀型阻燃剂对HIPS/OMMT复合材料阻燃性和抑烟性的提高更为显著。力学性能测试结果表明,APP体系的加入对复合材料的拉伸强度和冲击强度都有负面影响。Sodium montmorillonite was organically modified and the organc-montmorillonite was prepared. Both HIPS/OMMT composites and the flame retardant HIPS/OMMT composites of polyammonium tribasic phosphate （APP） system were prepared by melt-intercalation method. The results shows that the flame retardancy of HIPS/OMMT composites is improved compared with pure HIPS, but its enhancement is definite. Meanwhile, the flame retardancy and the smoke restrain of HIPS/OMMT composites of APP system is further im- proved, and it is more evident when APP system consists of APP, pentaerythrite and zinc borate than APP itself. The mechanical testing reveals that the tensile strength and the impact strength are reduced with the addition of APP flame retardant system.
