在以传统烫蜡工艺对缅甸花梨木表面进行改性蜂蜡烫蜡处理过程中,为了改善传统烫蜡后木材表面对紫外光的耐久性,采用疏水纳米SiO2对传统烫蜡用材蜂蜡进行共混改性处理. 以色度学参数、表面光泽度、接触角及纹理明显性为评价指标,探讨不同疏水纳米SiO2含量对烫蜡后木材表面耐紫外光性能的影响. 结果表明:疏水纳米SiO2的应用能有效增强木材表面颜色对紫外光的耐久性,纳米SiO2的加入均降低了烫蜡后木材表面光泽度,当疏水纳米SiO2加入量为1%时,处理材的光泽度最接近于未处理材;疏水纳米SiO2加入量为2%时,改性后蜂蜡处理材表面色差值最小,木材表面疏水性增强,对于提高烫蜡后花梨木表面紫外光耐久性最佳,紫外光辐射96 h后对木材纹理明显性的影响不大.

In order to effectively improve ultraviolet aging durability of traditional wax coating hardwood surface, tradi?tional beewax was modified by hydrophobic nano SiO2 using blending method. According to the traditional wax polish process, the surface of Bruma rosewood (100 mm×100 mm×10 mm) was treated with the modified bee wax. The ultravi?olet resistance was investigated through analyzing colorimetric parameters, surface gloss, contact angle and texture pros?perities change. The results showed that the application of hydrophobic nano SiO2 could effectively enhanced the ultravio?let durability of wood surface color. When the addition amount of hydrophobic nano SiO2 was 2%, the color difference of modified wood surface was minimum and the hydrophobic property of wood surface was also enhanced. The wood texture prosperities change was reduced by ultraviolet radiation 96 h. The addition of nano SiO2 reduced the wood surface gloss, and the surface gloss of wood surface treated by modified beewax with the addition hydrophobic nano SiO2 amount of 1%was close to the untreated wood. In addition, the optimal addition amount of hydrophobic nano SiO2 was 2% through the analysis of improvement of the ultraviolet durability.
