摘　　要：纳米铜锌防腐剂(Micro sized copper zinc compounds,MCZ)改性橡胶木耐腐性能可以达到国家Ⅰ级耐腐标准,但为适应复杂的环境应用,抗流失性和尺寸稳定性还需要进一步提高。使用丙二醇对MCZ进行改性(Propylene glycol-micro sized copper zinc compounds,PG-MCZ),再与单宁-硼酸联合对橡胶木进行协效处理。结果表明,当橡胶木浸渍PG-MCZ后再用质量浓度为1%的单宁-硼酸改性,处理材的抗流失性最佳。此时,橡胶木的抗湿胀性和抗干缩性效果最好,尺寸稳定性最佳,虽然加入丙二醇对橡胶木的防腐性有轻微减弱,但是仍然可以达到国家Ⅰ级耐腐标准,并且提高橡胶木的阻燃抑烟性。研究结果对促进环保木材防腐剂的开发利用具有积极作用。The corrosion resistance of modification rubberwood with micro sized copper zinc compounds(MCZ)can reach the national level I corrosion resistance standard,but in order to adapt to complex environmental applications,the leaching resistance and dimensional stability need to be further improved.Propylene glycol was used to modify MCZ,and then combined with tannin-boric acid for synergistic treatment of rubberwood.The results showed that when the rubberwood was impregnated with PG-MCZ and modified with tannin-boric acid with a mass concentration of 1%,the leaching resistance of the treated wood was the best.At this point,the modified rubberwood had the best anti moisture expansion and anti drying shrinkage effects,and the best dimensional stability.Although the addition of propylene glycol slightly weakened the corrosion resistance of rubberwood,it can still meet the national level I corrosion resistance standard and improve flame retardancy and smoke suppression of rubberwood.This study has a positive effect on promoting the development and utilization of environmentally friendly wood preservatives.
