摘　　要：研究了两种偶联剂——马来酸酐(偶联剂1)和异氰酸酯(偶联剂2)对木塑复合材料性能的影响。确定木材纤维与热塑性聚合物的比例7:3、复合材料的设计密度为0．7g／cm3,在热压温度175℃、热压时间8min、偶联剂1或偶联剂2 加入比例均为2％的试验条件下,对比分析偶联剂产生的作用。结果表明:偶联剂2对复合材料的力学性能影响显著;对于同一种偶联剂,所用的热塑性聚合物材料不同,对复合材料性能的影响也存在较大的差异。Impact of two coupling agents, maleic anhydride（coupling agent 1） and isocyanate （coupling agent 2） on properties of wood plastic composite （WPC） was studied. WPCs were made by using coupling agent 1 and coupling agent 2 respectively under the conditions of ratio of wood fiber to thermoplastic polymer 7：3, desired density of the composite 0.7g/cm^3, hot pressing temperature 175℃ hot pressing time 8 minutes and dosage of coupling agent 2 %, and the WPCs were tested. The results showed coupling agent 2 was superior to coupling agent 1, and had great influece on physical and mechanical properties of the WPC. When using the same coupling agent, different thermoplastic polymer had various impact on the properties.
