摘　　要：为开发人造板涂饰用高性能水性木器漆产品,进行水性木器漆配方设计,通过单因素试验,分析配方各成分的影响,筛选相应乳液和助剂,并用于中密度纤维板的涂饰。漆膜理化性能测试结果表明:丙烯酸乳液XK-14和聚氨酯改性丙烯酸乳液PR-100按35∶30的质量配比,辅以成膜剂5%、钛白浆22%时,漆膜硬度为2H,附着力为1级,耐醋、耐醇性能优异,总体性能满足相应标准要求,达到最佳。In order to meet the requirement of high-performance waterborne wood lacquer products for wood-based panels,waterborne wood paints were developed in the laboratory.The formulation design and coating performance were evaluated.The emulsion and auxiliaries were selected for the corresponding system.The properties of the waterborne film applied on medium-density fiberboard(MDF)were tested.The results showed that at the ratio of acrylic emulsion and polyurethane modified acrylic emulsion of 35∶30,with 5%film builder and 20%titanium white pulp,the coating hardness reached 2H,the adhesion strength reached Grade 1 of GB/T 9286—1998.The resistance of the coating to vinegar and alcohol were excellent.The overall performance of the waterborne coating was optimal.
