通过涂饰来提高木塑复合材料（WPC）的抗老化性能和赋予不同的装饰效果，是提高 WPC 的附加值和拓展其应用领域的重要途径。选用木蜡油、丙烯酸酯、聚氨酯、氟碳、有机硅和丙烯酸聚氨脂等6类共16种涂料，以自制的聚乙烯（PE）基木塑复合材料和聚丙烯（PP）基木塑复合材料为试材进行了涂饰，通过涂料接触角和漆膜附着力测试等方法对木塑复合材料的涂饰性能进行了评价。结果表明：涂料与聚乙烯基木塑复合材料的接触角低于聚丙烯基木塑复合材料，水性涂料与木塑复合材料的接触角明显高于同类成膜树脂的溶剂型涂料；漆膜附着力因涂料的种类和品种不同而异，多数涂料在聚丙烯基木塑复合材料的附着力略高于聚乙烯基木塑复合材料。综合考虑涂料接触角、漆膜附着力和外观等因素，以木蜡油、聚氨酯、丙烯酸聚氨酯、氟碳和有机硅为主要成膜物质的涂料对木塑复合材料的表面涂饰性能较好，其中有机硅和丙烯酸聚氨酯涂料更优。

@@@@Coating is a key pathway to increase the added value and expand applications of wood-plastic composite (WPC) by enhancing its anti-aging properties and decorative effects.Six types and sixteen kinds of coatings, such as wood wax, acry-late, polyurethane, fluorocarbon, silicone and acrylic polyurethane based coatings, were employed to paint polyethylene (PE)-based and polypropylene (PP)-based WPC samples.The coating contact angle and film adhesion were tested to e-valuate the finishing performance.The contact angle of PE-based WPC is lower than that of PP-based WPC, while the con-tact angle between waterborne coating and WPC material is higher than that of organic solvent coating based on the same film-forming resin.The film adhesion varies from the types and the kinds of the coatings, while the film adhesion between PP-based WPC and most coatings are slightly higher than that of PE-based WPC.Considering the factors of the coating contact angle, the film adhesion and the appearance, the coatings with wood wax, polyurethane, acrylic polyurethane, flu-orocarbon and organic silicon are good, and the coatings with the organic silicon and acrylic polyurethane are better.
