摘　　要：研究了聚烯烃弹性体(POE)对TPO树脂力学性能、硬度及熔体流动速率的影响,以及Mg(OH)_(2)填充改性TPO树脂的性能,结果表明:聚烯烃弹性体对TPO树脂具有很好的增韧改性效果,当聚烯烃弹性体含量为40%时,制得的改性TPO树脂的综合性能最佳;当改性Mg(OH)_(2)添加量为35%~40%时,共混料的综合性能较优,燃烧试验结果达到建筑材料燃烧性能等级中的B_(2)E级要求。This study investigats the effects of polyolefin elastomer(POE)on the mechanical property,hardness and melt flow rate of TPO resin,as well as the properties of TPO resin filled and modified with Mg(OH)_(2).The results show that polyolefin elastomer has a good toughening and modifying effect on TPO resin.When the content of polyolefin elastomer is 40%,the comprehensive performance of the modified TPO resin is optimal.When the addition of modifying Mg(OH)_(2) is 35%to 40%,the comprehensive performance of the blend is superior,and the combustion test results meet the B_(2)E level requirements in the combustion performance rating of building materials.
