摘要：【目的】提高热处理木材的防霉变性能,为扩大高温热处理木材的使用范围提供技术支撑。【方法】依据液相还原反应原理,以含铜浸渍液加压处理马尾松Pinus massoniana木材,运用木材热处理技术,获得热处理木材,依据改良的霉变箱法测试该材料的防霉变效力。【结果】对照组马尾松经高温220℃、3 h以上热处理之后,木材的防霉效力为20%以下;同等条件下,含铜马尾松热处理材防霉效力达90%以上。扫描电镜(SEM)与能谱(EDS)、X射线光电子能谱(XPS)和X射线衍射(XRD)表征含铜马尾松热处理木材内生成了纳米铜。【结论】含铜热处理木材受热原位生成的100 nm铜能够极大地提高木材的防霉变效力。
【Objective】To improve the anti-mold property of heat-treated wood and provide a technical support for expanding the use range of heat-treated wood.【Method】The Pinus massoniana wood was dipped in copper impregnated liquid with pressure according to liquid reduction reaction principle. The heat-treated wood was obtained by heat treatment technics, and anti-mold property of the wood was tested by modified mold culture box test method.【Result】The control group of P. massoniana wood was treated more than 3 hours at 220 ℃ and the mold-resistance effectiveness was lower than 20%. Under the same heat treatment condition, the mold-resistance effectiveness of P. massoniana wood which was impregnated in copper solution was more than 90%. The data of scanning electron microscope（SEM）, energy disperse spectroscopy（EDS）, X-ray photoelectron spectroscopy（XPS） and X-ray diffraction（XRD） showed that nano-copper was generated in copper-contained P. massoniana heat-treated wood.【Conclusion】The 100 nm copper produced in situ by heat treatment of copper-contained wood can greatly improve anti-mold property of wood.
