摘要

为开发刺槐木材涂饰工艺,分别采用聚氨酯漆、丙烯酸水性漆和合成大漆,对刺槐木材漆膜色度学参数和漆膜性能进行了评价。结果表明,这三种涂料对刺槐木材均表现出良好的涂饰效果,漆膜明度均存在下降趋势（其中合成大漆下降最明显）,漆膜色饱和度均增加;总体色差变幅最大为合成大漆,聚氨酯漆最小;漆膜性能均达到GB/T4893《家具表面理化性能测定法》和GB/T 15036-2009《实木地板》一级或二级要求,聚氨酯漆耐磨性、硬度最高。

Abstract

In order to coat Robinia pseudoacacia wood with paint, chromatic parameters and film performance of the wood coated with polyurethane varnish, acrylic lacquer and polymerized Chinese lacquer were evaluated. The results showed that Robinia pseudoacacia wood presented excellent coating performance with all three paints. The lightness index L* of the coated wood showed a downward trend with polymerized Chinese lacquer declined obviously. The color saturation C*ab of the coated wood all increased. Total chromatism ΔE*ab of the wood coated with polymerized Chinese lacquer showed the biggest varying breadth while the wood coated with polyurethane varnish showed the smallest varying breadth. The film performance of the coated wood could meet requirements of first-grade or second-grade of National Standard GB/T 4893 and GB/T 15036-2009. The film wear ability and hardness of the wood coated with polyurethane varnish showed the best performance.
