摘　　要：制备了不同配比的聚苯醚/高冲击强度聚苯乙烯(PPO/HIPS)合金,研究了阻燃剂对PPO/HIPS合金阻燃性能的影响以及SEBS-g-MAH对PPO/HIPS合金的增韧作用。结果表明:有机磷系阻燃剂对PPO/HIPS合金体系具有良好的阻燃协同作用,添加SEBS-g-MAH可以明显提高PPO/HIPS阻燃合金材料的缺口冲击强度;PPO/HIPS为60/40时合金的综合性能最佳,在此PPO/HIPS合金中添加12份阻燃剂及8份SEBS-g-MAH可以使其具有优异的阻燃性能,同时保持较高的力学性能。The Polyphenylene ether （PPO）/high impact polystyrene（HIPS） alloy with different mass ratio was prepared, and the effect of flame retardant on the flame retardant of PPO/HIPS alloy and the toughening effect of SEBS-g-MAH on PPO/HIPS alloy. The results show that the organic phosphorus flame retardant BDP right PPOIHIPS alloy system has a good fire-retardant synergy, add SEBS-g-MAH can significantly improve the impact strength of notched PPO/HIPS retardant alloy materials; when PPO/HIPS is 60/40, the overall performance of the alloy is the best, when fatherly adding 12 phr flame retardant and 8 phr SEBS-g-MAH, the alloy material has excellent flame retardant properties while maintaining a high mechanical propertie.
