木材防白蚁药剂研究概况及展望

木材作为一种重要的原材料,以它们优良的特性被广泛应用于建筑、家具和室内装修等领域,然而白蚁的威胁不仅缩短了木材的使用寿命,而且也限制了木材的应用领域：白蚁种类不同对木材的危害情况不一样,不同种类的木材其抗蚁性也有区别。目前,研究开发和应用的白蚁防治剂主要有砷制剂类、金属盐类、无机酸类、有机氯（氟）类、有机磷类、硅烷类、拟除虫菊酯类和有机杂环类等．无机白蚁防治剂和有机氯类因对人体和环境有害将逐渐遭到淘汰,拟除虫菊酯类药剂是目前世界上白蚁防治剂中品种最多的一类药剂,有机杂环类和一剂多效的环保型药荆将是今后的研究热点,对木材进行化学改性也将成为防治白蚁的一种方式。参39     

壳聚糖铜复合物处理后马尾松的防白蚁效果

Chitosan is a non-toxic natural biopolymer derived from chitin, which is the second most abundant natural polymer after cellulose in the world. Chitosan is easily cheated with metal salts and form chitosan metal complexes (CMC). In this study, Masson Pine (Pinus massoniana) as test species, chitosan copper complex(CCC), modified chitosan copper complex (M-CCC) and CCB as wood preservatives to termite attack. The experiment was conducted according to AWPA E1-97(AWPA 1999) and GB/T18260-2000 in order to evaluate the termite resistance effects of CCC and M-CCC in comparison with CCB. Results showed that all of the chosen preservatives had good resistance against termites ( Coptotermes formosanus ), among which, M-CCC beheld the best, and the synthetical rating exceeded 100.
