摘　　要：采用大漆对竹材进行涂饰处理,研究大漆涂饰竹材的吸湿性、尺寸稳定性、水浸润性及表面疏水性,综合评价大漆涂饰竹材的防潮性能。研究表明,在模拟的6种湿热环境中大漆涂饰竹材的含水率均大幅低于素材的含水率,尺寸稳定性显著提高,水接触角增大,表面自由能明显下降,大漆涂饰竹材的防潮能力得到增强。The article studies on lacquer painting bamboo＇s hygroscopicity,dimensional stability,water infiltration and hydrophobicity in order to evaluate its moisture-proof performance.The research shows that the rate of water content of bamboo coated by lacquer is lower than bamboo,the dimensional stability reports a marked increase,the water contact angle is magnified,and the surface free energy is enhanced.So the moistureproof performance of bamboo coated by lacquer is increased.
