摘　　要：通过正交试验,以木材纤维和废旧聚丙烯塑料为原料,异氰酸酯或马来酸酐作偶联剂,压制木材纤维/聚丙烯复合材料,研究聚丙烯(简称PP)用量对木塑复合材料性能的影响。结果表明,聚丙烯比例对复合材料的内结合强度、吸水厚度膨胀率、静曲强度和弹性模量有不同的影响。在热压时间、热压温度、复合材料密度相同的条件下,用异氰酸酯(简称MDI)作偶联剂,聚丙烯用量40%时复合材料的性能最佳;而用马来酸酐(简称MA)作偶联剂,聚丙烯用量50%时复合材料的性能最佳。Through multi-factor orthogonal experiment, wood fiber/plastic： composite was manufactured to study the effects of polypropylene content on properties of wood fiber/plastic composite by using wood fiber and recycled polypropylene（PP） and MDI or MA as coupling agent. The results showed that polypropylene content has different effects on the IB, TC, MOR and MOE. On the same condition of hot-pressing time, hot-pressing temperature and density of composite, the optimum properties of composite were obtained when recycled polypropylene content is 40% by using MDI as coupling agent and recycled polypropylene content is 50% by using MA as coupling agent.
