In order to prepare metal-free water-borne organic wood preservatives, BAC 、carbendazim and imidacloprid were chosen as components of the preservative and a steay water-borne organic wood oreservative was obtained under conditions of 5 ％ BAC,2 ％ carbendazim, 1％ imidacloprid and 10 ％ emulsifier. 30 min of emulsification time, 70 ℃ of emulsification tempreture and 1000 r/min of stirring speed. The results of the experiment showed that the perservatives have good performances in anti-rot、anti-mould and anti-leaching for wood. Preservative effects against Coriolus versicolor and Gloeophyllum trabeam reached first degree at dosage of 3.20 and 7.58 kg/m3 respectively. Effects against Aspergillus niger and Trichodemaviride reached zero degree at dosage of 0.354 and 0.372 kg/m3 doses respectively. Two-phase titration、ultraviolet spetrophotometry and infared spectroscope were used to detect the leachability of BAC、carbendazim and imidacloprid, the results showed that these components have good performance in anti-leachability. The loss rate of the BAC, carbendazim and imidacloprid was 9.44％,8.50％, 9.17 ％ respectively in the 3.20 g/m3 does.%为了制取不含金属的水载型有机木材防腐剂,选择十二烷基二甲基苄基氯化铵(BAC)、多菌灵和吡虫啉作为木材防腐剂的组分,以5%BAC、2%多菌灵、1%吡虫啉和10%乳化剂的配方,在乳化时间30 min、乳化温度70℃、搅拌速度1 000r/min的条件下进行乳化,得到稳定的水载型有机木材防腐剂.对木材防腐剂进行防腐、防霉实验和抗流失实验,结果表明防腐剂在载药量3.20和7.58 kg/m3时对彩绒革盖菌和密粘褶菌的防腐结果达到一级;在载药量为0.354和0.372 kg/m3时曲霉素和绿色木霉对木材的危害为0级,显示了较好的防腐和防霉效果;用两相滴定法、薄层-紫外分光光度法和红外光谱法检测浸泡液中BAC、多菌灵、吡虫啉3种有效成分的流失性能,3种有效成分具有较好的抗流失性.在载药量为3.20kg/m3时,BAC流失率为9.44%,多菌灵流失率为8.50%,吡虫啉流失率为9.17%.
