Curing rule of microcapsules preservatives prepared from neem extracts in wood

  • 摘要: 目的印楝是一种抑菌效果优良的天然材料,这种材料不仅可以防止木材腐朽而且不会污染环境。使用印楝种子提取印楝植物活性成分,将其制备成微囊防腐剂,探究该防腐剂在木材中受温度影响的固化规律及抑菌性能。方法首先利用印楝提取物制备微囊防腐剂预制剂,使之能够更好地进入木材中,再通过程序升温的方法来比较在不同温度控制下微囊防腐剂在木材中的成囊情况。同时,通过褐腐菌抑菌实验考察防腐剂的抑菌性能。使用褐腐菌侵蚀不同处理的樟子松试件12周,通过试件的质量损失率来表征耐腐性能。通过40、50、60、70、80 ℃程序升温处理后的大青杨试件微观电镜图,分析印楝提取物微囊防腐剂在木材中的固化规律。结果经80 ℃升温处理后的樟子松细胞腔内也形成了微囊结构。褐腐菌抑菌实验结果显示:受褐腐菌侵蚀后,樟子松试件对照组质量损失率达到21.05%;经印楝种子提取物处理的试件质量损失率为10.96%,达到耐腐标准;经MUF处理的试件质量损失率为29.23%;经印楝提取物微囊防腐剂处理的试件质量损失率为6.01%,达到强耐腐等级。结论随着升温温度的升高,固化形成的微囊颗粒呈减小趋势,且在木材细胞壁中的分布更为均匀,结合更为紧密。印楝提取物制备的微囊防腐剂达到强耐腐等级,这说明印楝提取物制备的微囊防腐剂具有较好的防腐效果,而且防腐效果较持久。
