摘　　要：以杨木为试材 ,比较了 3种季铵盐木材防腐剂的防腐性能和抗流失性。结果表明 ,当二癸基二甲基氯化铵 (季铵盐 1 )、二癸基二甲基乙酸铵 (季铵盐 2 )和二癸基二甲基丙酸铵 (季铵盐 3)药剂的保持量分别为3.8,3.8和 3.9kg/m3 时 ,经白腐采绒革盖菌 [Coriolusversicolor(L .exFr.)Quel]腐朽后 ,试样的质量损失率分别为 7.2 % ,7.9%和 7.6 % ,达到强耐腐等级。另外 ,二癸基二甲基乙酸铵与木材作用后 ,对中性和碱性溶液性质较为稳定 。Comparison on decay- and leach-resistances among 3 quaternary ammonium salts,namely:didecyl dimethyl ammonium chloride,didecyl dimethyl ammonium acetate and didecyl dimethyl ammonium propionate,as wood preservatives were conducted by applying them to Populus ussuriensis,wood specimen,using Coriolus versicolor(L.ex Fr.)Quel as test fungus.At the retention of 3.8, 3.8, 3.9 kg/m 3,testing results showed the mass loss to be 7.2%, 7.9%, 7.6%,respectively.Didecyl dimethyl ammonium acetate in wood showed stability against neutral and alkaline solutions,whereas the propionate showed stability against acidic solution.
