摘要:
通过对橡胶木进行热改性处理和糠醇浸渍处理,采用PE或PU组分清漆进行涂饰,对涂饰前后试材的材色和光泽度进行研究。结果表明:糠醇改性材与热改性材涂饰前后的色差值为12~24,PE涂饰的变化值略大于PU涂饰;色度指标中,对照材和改性材的明度L*均降低,但红绿度和黄蓝度的变化则与改性方法、改性程度有关;170 ℃热改性材的红绿度和黄蓝度明显上升,210 ℃热改性材的红绿度和黄蓝度则明显下降;高增重率糠醇改性材的红绿度和黄蓝度均显著下降,而低增重率的红绿度基本不变、黄蓝度下降明显;改性和涂饰缩小木材顺纹和横纹方向的光泽度差异,但PE和PU涂饰之间的差异不明显。
Abstract:
The color and gloss of rubberwood before and after painting were studied by heat treatment and furfuryl alcohol impregnation with PE or PU varnish. The results showed that color difference of modified rubberwood varied from 12 to 24, while color difference with PE painting was a little bigger than that with PU. The lightness L* of modified woods and control woods decreased, while red-green index and yellow-blue index varied with the method and degree of modification. The red-green index and yellow-blue index of the thermal modified wood increased obviously at 170℃, and decreased at 210℃. The red-green index and yellow-blue index of Furfuryl alcohol modified material with high rate of gaining weight decreased significantly, while red-green index of that with low rate of gaining weight basically unchanged, and yellow-blue index decreased significantly. Modification and painting can fill the gap between the gloss along the grain and transverse the grain, while gloss of painted samples with PE and PU varnish doesn′t show significant difference.
