摘　　要：采用水性丙烯酸(T1)、自交联聚氨酯改性水性丙烯酸(T2)、水性聚氨酯丙烯酸(T3)对家具用竹集成材进行涂饰,探究不同的丙烯酸种类、涂饰方式及涂布量对漆膜性能的影响。结果表明:水性丙烯酸种类对漆膜性能有一定影响,T3底漆和面漆的表干/实干时间较快,底漆为8 min/8.5 min、第一次面漆为7 min/7.5 min、第二次面漆为6 min/6.5 min,T2和T3的硬度略高于T1,均为B级,附着力均为0级。综合比较下,T3的性能较佳。涂饰方式对漆膜性能影响不明显,不同涂饰方式下底漆表干/实干时间为8 min/8.5 min,面漆表干/实干时间为6.5 min/7 min,其硬度和附着力均为B级和0级,一底一面涂饰下漆膜耐磨性较佳,为51.24 mg·100 r^(-1)。涂布量对漆膜性能影响较大,漆膜表干/实干时间会随着涂布量的增加而增大,涂布量为80 g·m^(-)2时漆膜的附着力、硬度及耐磨性最佳,分别为0级、B级和51.24 mg·100 r^(-1)。Waterborne acrylic acid(T1),self-cross-linked polyurethane modified waterborne acrylic acid(T2),and waterborne polyurethane-acrylic acid(T3)were applied to finish the bamboo laminated lumber for furniture,and the effects of different acrylic acid types,finishing methods,and coating amounts on the properties of the paint films were investigated.The results showed that the type of waterborne acrylic acid had an impact on the properties of the paint film.The surface drying time/hard drying time of primer and topcoats under T3 treatment were relatively shorter,with 8 mins/8.5 mins for primer,7 mins/7.5 mins for first topcoat,and 6 mins/6.5 mins for second topcoat.The hardnesses of the paint films under T2 and T3 treatments were slightly higher than that under T1,which were both at grade B with the adhesion of grade 0.Therefore,T3,by comparison,yielded better performance.The effect of the coating method on the paint film′s performance was not significant.The surface drying time/hard drying time of primer was 8 mins/8.5 mins,and the surface drying time/hard drying time of topcoat was 6.5 mins/7 mins.The hardness remained at grade B and the adhesion at grade 0.A better abrasion resistance of the paint film was achieved with one primer one topcoat finishing,which equaled to 51.24 mg·100 r^(-1).The coating amount had a significant impact on the properties of the paint film.The surface drying time/hard drying time of the paint film increased as the coating amount increased.The optimal adhesion(grade 0),hardness(grade B),and abrasion resistance(51.24 mg·100 r^(-1))were obtained when the coating amount was 80 g·m^(-2).
