摘　　要：开发了一种简单、高收率的方法,实现了聚苯乙烯的磷酸酯功能化改性,制备磷酸酯功能化的聚苯乙烯PS-P材料。PS-P材料的最大放热温度、最大放热速率和总放热量相比于聚苯乙烯原料均有大幅度下降,具有优异的阻燃潜力。质量分数3%的PS-P材料的加入即可使PLA具有阻燃性,达到UL-94标准下的V-2等级以及21.5%(体积分数)的极限氧指数。此外,PLA/3PS-P阻燃复合材料保持了56.9 MPa的机械强度,具有实际应用前景。A simple and high yield method was developed to realize the functional modification of polystyrene with phosphate ester,and the PS-P material with phosphate ester functionalization was prepared.The maximum heat release temperature,heat release rate and heat release capacity of PS-P material were significantly reduced compared with polystyrene,and PS-P material had excellent flame-retardant potential.PLA3PS-P composite achieved a UL-94 V-2 grade and 21.5%LOI.In addition,PLA/PS-P flame-retardant composites maintained the mechanical strength of 56.9 MPa,having practical application prospects.
