摘要：壳聚糖金属聚合物 [如壳聚糖铜聚合物 (CCC)和壳聚糖锌配合物 (CZC) ]是壳聚糖和金属盐类反应生成的一种新型有机高分子聚合物。用CCC和CZC与铜铬砷 (CCA)分别处理马尾松和毛白杨边材 ,进行木材防腐试验 ,结果表明 :CCC和CZC对褐腐菌棉腐卧孔菌的防腐性能与CCA相比 ,CZC达到最耐腐等级 ,防腐效果接近CCA ,其锌离子临界保持量为 0 780kg·m- 3(腐朽后质量损失 1 18% ) ,但CCC防褐腐效果明显不如CZC ;CCC对白腐菌彩绒革盖菌的防腐性能达到最耐腐等级 ,防腐效果接近CCA ,其铜离子临界保持量为 0 82 4kg·m- 3(腐朽后质量损失2 4 5 % ) ;CZC和氯化锌对白腐菌的防腐效果不明显。
Chitosan, a natural and renewable polymer without toxic and pollution to human beings and environment and the deacetylated derivative of chitin that mainly exist in the crusts of crabs and shrimps, has many good characteristics and used into many fields such as agriculture, medicine, chemistry, etc.Chitosan metal complex (CMC), one new potential wood preservative, which produce from the chemical reaction between chitosan and some metal salts such as copper or zinc salts are shown to be effective but low-toxicity preservatives for wood. This paper reported the decay resistance of Pinus massoniana and Populus tomentosa treated with chitosan copper/zinc complex (CCC and CZC)against the brown and white rot fungi. The results showed that the decay resistance of CZC against brown rot fungi (Poria placenta) treated to P. massoniana wood were equivalent with CCA, and remarkably better than that of only treated by relevant metal salts and chitosan, but CCC had little effectiveness against brown rot fungus. The threshold retention of zinc ion in CZC treating solution was 0.780 kg·m -3 (mass loss 1.18); also decay resistance of CCC against white rot fungi (Coriolous versicolor) was equivalent with CCA, and remarkably better than that of only treated by relevant metal salts and chitosan, while the CZC against white rot fungi was not good. The threshold retention of copper ion in CCC treating solution was 0.824 kg·m -3 (mass loss 2.45).
