Preparation method of light-aging-resistant bamboo material and application of light-aging-resistant bamboo material in outdoor materials

The invention discloses a preparation method of a light-aging-resistant bamboo material. The preparation method comprises the following steps: step 1, preparing a bamboo inner plate and a bamboo surface plate; 2, delignification treatment is conducted on the bamboo surface board, and delignified veneers are obtained; and 3, the delignification veneer is glued and then placed on the surface of the bamboo inner plate, and then the light aging resistant bamboo material is obtained through pressing. The delignification veneer is used as the surface board of the bamboo material, so that the outdoor light aging resistance of the material can be effectively improved.
