摘　　要：[Objective]Preservation and waterproof treatment are two crucial parts in wood protection, which can not only extend the service time, but also expand the application range of wood products. [Method] This work combined CA with paraffin wax emulsion to treat wood samples, and basic properties of the compound system, such as stability （storage stability and centrifugal stability）, particle size and pH val-ue, and water repel ency （water absorption, shrinkage and swel ing） of treated sam-ples were investigated. [Result and Conclusion] 1） the compound systems of CA and paraffin latex had a favorable miscibility and stability; 2） compared with untreated wood, CA-treated samples showed poor water repel ing properties, whereas samples treated with the compound systems indicated an obvious reduction in water absorp-tion, and the shrinkage and swel ing of them were improved as wel .[目的]木材的防腐与防水,是木材保护的重要方面,它对延长木材的使用寿命、拓宽其应用范围具有重要的意义。[方法]本研究以环保型防腐剂铜唑(CA)与石蜡乳液防水剂复合处理木材,并对复配体系的基本性能,包括稳定性(储存稳定性和离心稳定性)、粒径和pH值等,以及复配处理材的防水性(吸水性、干缩性及湿胀性)进行了考察。[结果及结论]研究发现:(1)CA与石蜡防水剂进行复配具有良好的混容性及稳定性,不同配比的复配体系其储存稳定性与离心稳定性均可达到1级水平,可存放较长时间不致出现破乳现象。(2)CA不能改善处理材的防水效果。但是,经CA与石蜡防水剂复配体系处理的试材,其吸水性和尺寸稳定性均得到明显改善。
