摘　　要：以热空气干燥工艺对喷涂两遍水性封闭底漆的硬枫薄木贴面家具板件进行干燥处理,漆膜固化后,用拉力法测试层间附着力强度。结果表明:影响附着力的主要因素是湿度,温度对其影响不大,优化热空气干燥工艺只能在一定程度上改善漆膜的附着力。采用空气温度为35℃和湿度为50%的热空气对第1遍封闭底漆进行干燥,空气温度为35℃和湿度为70%的热空气对第2遍封闭底漆进行干燥,可以获得较好的漆膜附着力。Veneered maple furniture panels were sanded and sprayed by two pieces of water-borne sealer. Wet coating was dried by the hot air using process parameters. Adhesion of dried coatings was tested with the pulling method. The results showed that humidity of hot air was very important, but its temperature has minor effects on adhesion of coatings at a certain extent. It was seen that when 35℃ hot air with 50% humidity was firstly used to dry the sealer and the second was 35℃ hot air with 70% humidity, the beater adhesion of the sealer was obtained.
