研究微胶囊红磷(MRP)和聚苯醚(PPO)复合阻燃剂对高抗冲聚苯乙烯(HIPA)材料力学性能的影响,并用抗冲击改性剂ABA及AEBA对高抗冲聚苯乙烯(HIPS)/微胶囊红磷(MRP)/聚苯醚(PPO)无卤阻燃材料的抗冲击性能和阻燃性能进行优化。结果表明:MRP和PPO的加入均会使HIPS体系的冲击性能下降,抗冲击改性剂ABA及AEBA的加入改善了无卤阻燃HIPS的悬臂梁冲击强度,且对材料的阻燃性没有影响,制得增韧改性后的无卤阻燃HIPA材料具有优异的阻燃和力学等综合性能。
The effects of MRP and PPO on the mechanical properties of high impact polystyrene (HIPA) were studied. The effects of high impact polystyrene (ABA) and AEBA The impact resistance and flame retardancy of HIPS / MRP / PPO halogen-free flame retardant materials are optimized. The results showed that both the addition of MRP and PPO decreased the impact properties of HIPS system. The addition of impact modifiers ABA and AEBA improved the Izod impact strength of HIPS without affecting the flame retardancy , The toughening-modified halogen-free flame retardant HIPA material has excellent comprehensive properties of flame retardancy and mechanics.
