摘　　要：以聚氯乙烯(PVC)基木塑复合材料(WPC)为研究对象,通过单因素试验法研究WPC中的发泡剂用量对WPC界面性能的影响,并通过物理性能、力学性能、界面相容机理以及界面结合性能等对WPC的界面性能进行表征。结果表明:当发泡剂用量为1.0份时,木粉与PVC树脂之间的界面相容性良好,界面结合力最强,且其物理力学性能较好。Taking PVC-based wood-plastic composites(WPC)as the research object,the effect of the amount of foaming agent in WPC on the interfacial properties of WPC was studied by single factor test.The interfacial properties of WPC were characterized by physical properties,mechanical properties,interfacial compatibility mechanism and interfacial bonding properties.The results show that when the dosage of foaming agent is 1.0 phr,the interfacial compatibility between wood flour and PVC resin is good,the interfacial bonding strength is the strongest,and the physical and mechanical properties are good.
