Abstract

本发明提供了一种木材防腐剂,以氮水为溶剂,以铜化物,烷基铵化物为有效成份组成的混合物,解决了现有木材防腐剂中因有大量的砷、铬而对人畜造成的危害,具有高效低毒的特点。所述铜化物能溶解于氨水,所述烷基铵化物应具有杀菌效果。

Description

木材防腐剂
本发明涉及一种木材防腐剂。
目前世界各国广泛使用的木材保护剂为CCA防腐剂,该种防腐剂含有砷、铬等物质而具有毒性,不利于环境保护。
本发明的目的就是针对上述情况,提供一种高效低毒的木材防腐剂。
本发明以氨水为溶剂,以铜化物,烷基铵化物为有效成份组成的混合物,所述铜化物能溶解于氨水,如氢氧化铜,碳酸铜等,所述烷基铵化物是指有杀菌效果的烷基铵如二甲基二癸基氯化铵,二甲基十二烷基苄基氯化铵等,其中有效成份中的铜化物与烷基铵化物的重量比为10-90∶90-10,所述溶剂氨水的用量是铜化物重量的1-10倍,本发明的作用机理是:进入木材以后,由于氨的蒸气压较高,很容易挥发,难溶于水的铜化物与木材因络合而固化,在木材中起毒效作用,烷基铵化物作为阳离子表面活性剂与木材发生离子交换而固化。本发明同现有的木材防腐剂(CCA)相比有如下特点:
1、不含砷和铬,高效而低毒。
2、溶液为蓝色,而CCA溶液为褐红色,处理木材颜色比CCA处理颜色浅,容易为人们所接受,特别是用于圆林木的处理时,处理材表面颜色更容易与环境产生和谐的美感。
3、在处理罐中,不会象CCA那样产生沉淀和残渣。
4、对人畜毒性很低。

Claims (1)

1、一种木材防腐剂,其特征是以氨水为溶剂,以铜化物,烷基铵化物为有效成份组成的混合物,所述铜化物能溶解于氨水,如氢氧化铜、碳酸铜等;所述烷基铵化物是指有杀菌效果的烷基铵,如二甲基二癸基氯化铵、二甲基十二烷基苄基氯化铵,有效成份中的铜化物与烷基铵化物的重量比为10-90∶90-10,所述溶剂氨水的用量是铜化物重量的1-10倍。
