摘　　要：制备了阻燃麦秸纤维增强废旧聚丙烯再生复合材料,研究了阻燃剂Al(OH)_3含量对复合材料阻燃及力学性能的影响。结果表明:Al(OH)_3的加入极大地提高了复合材料的阻燃性能,并减少了融滴现象,当Al(OH)_3质量分数为40%时,垂直燃烧级别达到FV-0级,极限氧指数达到28.9;Al(OH)_3的添加使复合材料的热分解温度明显提高;随着Al(OH)_3含量的增加,复合材料的拉伸强度、弯曲强度、冲击强度呈现先升高后降低的趋势,当Al(OH)_3质量分数为30%时,复合材料的阻燃性能和力学性能达到最佳组合。Recyled flame retardent wheat straw fiber reinforced waste polypropylene（PP） composites were prepared. The influence of Al（OH）3 content on the flame retardancy and mechanical properties of the composite was studied. The results show that Al（OH）3 significantly improved the flame retardancy and anti-dripping performance of the composites. When 40wt% AI（OH）3 was added, the vertical burning level of the composites achieved FV-0, and the limiting oxygen index value was 28. 9. The decomposition temperature of the composites was increased by the addition of Al（OH）3. With the increase of Al（OH）3 content the tensile strength, bending strength and impact strength of the composite, tended to increase first and then decrease. When the Al（OH）3 content was 30wt%, the composite had the best combination of flame retardaney and mechanical properties.
