提高木材整体疏水性的方法
摘要：
本发明涉及一种提高木材整体疏水性的方法。先用正己烷将疏水试剂烷基烯酮二聚体(AKD)溶解，配成2～10∶100质量浓度的溶液；然后在真空-高压浸渍工艺中，先让木材在真空度为-0.09兆帕下保持15分钟～60分钟，然后将2～10∶100质量浓度的AKD正己烷溶液吸入浸渍罐内，加压至1.0兆帕～3.0兆帕，并在高压状态下保持0.5小时～4小时；最后将处理后的木材在100℃～120℃温度加热1小时～5小时。使AKD与木材中的纤维素发生化学反应，制成木材内外均有疏水性的功能木材。从而，具有处理工艺简单，疏水效果显著，是提高木材整体疏水性能的新方法。
摘要（英）：

The invention relates to a method for improving the whole hydrophobicity of wood. The method comprises the steps of dissolving a hydrophobic reagent (namely Alkyl Ketene Dimer (AKD)) by hexyl hydride, preparing solution with the mass concentration being 2-10:100; then in a vacuum-high pressure dipping process, keeping the wood in the environment with the vacuum degree being -0.09MPa for 15-60min, then sucking the AKD hexyl hydride solution with the mass concentration being 2-10:100 in a dipping tank, pressurizing to be 1.0MPa-3.0MPa, keeping for 0.5h-4h under a high pressure state; and finally, heating the processed wood for 1h-5h under the temperature being 100 DEG C-120 DEG C. Therefore, the AKD and the cellulose in the wood are subjected to chemical reaction, so as to produce functional wood with whole hydrophobicity. According to the new method, the process is simple, the hydrophobic effect is obvious, and the whole hydrophobicity of the wood can be improved.
