摘　　要：水载型木材防腐剂在木材防腐市场中占据着主导地位,然而其中的有效成分的抗水流失性差是其存在的主要缺点,这在很大程度上是由于防腐处理材在使用前防腐剂有效成分与木材成分之间的固着反应不充分而造成的,因此提高防腐有效成分在处理材中的固着质量是提高抗流失性的关键。笔者对国内外在水载型防腐剂中有效成分固着方面的研究进行了较为系统、全面的介绍,其中包括木材树种、固着的环境温度与相对湿度、固着时间、木材含水率、防腐剂的保持量、防腐剂成分组成等不同因素的影响,并在此基础上提出了今后的研究方向。Water-borne preservatives are predominant ones in wood preservation market in recent years. However, the active ingredients in the preservatives are vulnerable to leach out during service. The most important reason is attributed to the incomplete fixation of the active ingredients in the treated wood. Therefore, the key point to improve the leaching resistance of the active ingredients is to ensure the fixation quality of the ingredients in the preservative-treated wood. This paper presents an overall introduction of the recent investigations to the fixation of active ingredients in wood treated with water-borne preservatives, including the influence of wood species, environment temperature and relative humidity, fixation duration, wood moisture content, wood preservative retention, wood preservatives formula etc. The expectations of future wood preservation research are also put forward.
