多酚-铁溶液浸渍处理对红锥薄木颜色及耐光色牢度的影响
Effect of Impregnation with Polyphenol-Iron Solution on the Color and Light Fastness of Castanopsis hystrix Veneer
摘要
Abstract
To enrich the color and improve light fastness of Castanopsis hystrix veneer,the main raw materials such as tannic acid,gallic acid,ferrous sulfate,and subchloride were used to create five types of polyphenol-iron solutions.Wood veneers were soaked at atmospheric pressure to achieve various colors of decorative materials,and a photoaging method using xenon lamp was employed to evaluate the color fastness to light.The results showed that wood materials decorated with cold color,primarily grey-black and blue-black,were achieved through impregnation treatment with polyphenol-iron solution.Among five solutions,the decorative materials prepared with dye solution(FeSO4+TA+GA)exhibited the best color fastness to light,achieving a lightfastness level of 3.The total color difference before and after photoaging was 4.25,which was 46.34％lower than that of the control veneer.The Fe2+and Fe3+in the polyphenol-iron compound transformed into each other in the environment of oxygen and polyphenols,consuming free radicals in the system and reducing the oxidation of phenolic substances in the substrate into darker quinones.Thus,the light aging resistance of the finishing material was improved.关键词
