摘　　要：研究了氨溶性季铵铜(ACQ)防腐剂对尾巨桉表面颜色及防腐性能的影响。结果表明:经ACQ浸渍后,尾巨桉木材的明度L^(*)、红绿轴色品指数a^(*)、黄蓝轴色品指数b^(*)和色度值C均显著降低。经浓度为2%、4%和8%的ACQ浸渍处理后,尾巨桉对绵腐卧孔菌(PV)均达到了Ⅰ级耐腐水平。经8%的ACQ浸渍处理后,尾巨桉对彩绒革盖菌(CV)也达到Ⅰ级耐腐水平。SEM测试进一步确认了较高浓度的ACQ更有利于提高尾巨桉的耐腐性。FT-IR结果表明,ACQ与尾巨桉木材中的木质素和半纤维素发生了结合。该研究对尾巨桉的耐腐性改良具有重要意义。The effect of amine copper quant(ACQ)preservative treatment on the surface color difference and corrosion resistance of Eucalyptus urophyllax×E.grandis was studied.The results showed that the brightness L^(*),color index a^(*)(red-green axis),b^(*)(yellow-blue axis)and chromatic value C of Eucalyptus urophyllax×E.grandis specimens were significantly reduced after ACQ impregnation.Eucalyptus urophyllax×E.grandis reached class I decay resistance for PV after 2%,4%and 8%ACQ impregnation,while only 8%ACQ impregnation reached class I decay resistance for CV.SEM test further confirmed that higher concentration of ACQ was more conducive to improving the corrosion resistance of Eucalyptus urophyllax×E.grandis.FT-IR results showed that ACQ mainly bonded to lignin and hemi-cellulose in Eucalyptus urophyllax×E.grandis.This study had important significance for the improvement of decay resistance of Eucalyptus urophyllax×E.grandis.
