Abstract

The invention relates to a preparation method of a light-transmitting wood material with light-emitting and energy-storing functions. The method comprises the following specific steps that 1, delignification treatment is conducted on wood; 2, a resin composite material with light-emitting and energy-storing functions is prepared by using a melt blending method; and 3, vacuum impregnation is carried out on a delignified wood template by using the prepared resin composite material to obtain the light-transmitting wood material with light-emitting and energy-storing functions. The method has thefollowing advantages: 1) the method is simple to operate, does not need a large amount of reagents, and is green and environment-friendly; 2) the mechanical property of the wood is better than before;3) the treated wood has higher light transmittance and haze; 4) the light-transmitting wood material prepared through the method has a good energy storage function, and 5) the light-transmitting woodmaterial can absorb and store visible light and ultraviolet light, can be released in the form of visible light, has a self-luminous function. The light-transmitting wood material aims to solve the problem that an existing light-transmitting wood material does not have luminous and energy storage functions.

Description

technical field [0001] The invention relates to a method for preparing a light-transmitting wooden material with functions of luminescence and energy storage. Background technique [0002] Energy is the basis for human survival. With the development of the economy, the consumption of energy continues to increase, and a lot of research work is devoted to improving the efficiency of energy use and reducing energy consumption. The advantages of wood as a biomass material in terms of its renewable and environmental friendliness are gaining increasing attention. Wood has many advantages such as high strength-to-weight ratio, good thermal insulation performance and environmental coordination performance, and is widely used in the field of construction. As a new type of biomass material, light-transmitting wood can save energy and has attracted extensive attention at home and abroad. [0003] Today, with the development of material science and technology, materials with a single...
