摘　　要：以人工林速生材桉木为基材,聚氯乙烯膜代替传统胶黏剂制备木塑复合材料,解决了甲醛释放、白色污染等问题。采用热压—冷压工艺,以热压温度、时间及塑料添加量3个因素为自变量,胶合强度为响应值,通过响应面分析确定了最优生产工艺;并采用扫描电子显微镜观察其界面形态,即热压温度为183℃,热压时间为452 s,塑料添加量为320 g/m^2。试验表明:桉木单板/聚氯乙烯膜制备木塑复合材料工艺具有可行性,其胶合强度达1.14MPa,满足GB/T 9846—2015标准中Ⅱ类胶合板的要求。To solving pollution problems such as formaldehyde and white pollution,we used the fast-growing eucalyptus wood as based material and Polyvinyl chloride film which insteaded traditional adhesive to make wood-plastic composites materials by hot-cold pressing crafts. Hot-pressing temperature,time and the amount of plastics as the independent variable,bonding strength as the response value,we used response surface methodology to optimize the best processing factor,and analyzed the fractural surfaces of samples by a scanning electronic microscope. The best processing factor was hot-pressing temperature of 183 ℃,hot-pressing time of 452 s and PVC films of 320 g / m^2. Therefore,it is feasible to make wood-plastic composites by using eucalyptus wood and PVC film. The plywood bonding strength reached 1.14 MPa,which met the requirement of Type Ⅱplywood according to the National Standard of GB / T9846-2015.
