| 摘 要： | 壳聚糖是一种无毒害且可再生的天然讷发子材料，可用于木才表面改性处理。本文通过对杉木边材、心材和毛白杨边材表面涂饰不同浓度的壳聚糖乙酸溶液，测定分析处理前后的木才材色变化。结果表明：不同深度壳聚糖处理木材表面，处理产后总体色差随深度的升高而增加，其它色度学参数略有变化；壳聚糖处理木材表面的最佳深度是２．０％，处理后对木才表面的进一步着色或涂饰无大影响。

| Abstract: | Chitosan is a natural and renewable polymer extracted mainly from crabs and shrimps without toxic and pollution to human beings and environment and can be used to the wood surface modification such as wood dyeing and clear painting.But the information of changes of color characteristics of wood painted with chitosan is absent.In this paper the color characteristics of unpainted and painted wood with aqueous solution of chitosan at 0 5,1 0,1 5,2 0,2 5 and 3 0% concentration for sapwood of Chinese Fir (Cunninghamia lanceolata ) and Chinese White Poplar (Populus tomentosa) ,heartwood of Chinese Fir were measured and analyzed.The results showed that all the color difference went up as the concentration of an aqueous solution of chitosan painted wood increased while the other parameters vary little between unpainted and painted wood.2% of an aqueous solution of chitosan is the best concentration for wood dyeing or clear painting with no influence to further surface treatment. |
