Modification method for improving teak product surface light-aging-resistant performance

The invention relates to a modification method for improving the teak product surface light-aging-resistant performance. The method includes the following steps that (1) seed solution preparation is carried out, wherein zinc acetate and sodium hydroxide are dissolved into methyl alcohol to be stirred to form a seed solution; (2) preparation of growth-promoting media is carried out, wherein zinc nitrate and hexamine are dissolved into water to be stirred to form the growth-promoting media; (3) surface crystal seed layer preparation is carried out, wherein a teak product is soaked into the seed solution prepared in the step (1), and then drying treatment is carried out; and (4) surface crystal growth is carried out, wherein the teak product treated in the step (3) is soaked into the growth-promoting media prepared in the step (2), and drying treatment is carried out. The modification method has the beneficial effects that the good maneuverability is achieved, automatic and continuous production is achieved, the
