Abstract

The invention relates to a preparation method of a light-transmitting wood energy storage material. The method specifically comprises the following steps: (1) performing delignification treatment on wood to prepare a wood template subjected to delignification; (2) preparing a resin composite material with a energy storage function by a melt blending method; and (3) performing vacuum impregnation on the wood template subjected to delignification by using the prepared resin composite material to fully fill cell cavities and cell walls of the wood to obtain the light-transmitting wood energy storage material. The method has the following advantages: 1) the method is simple to operate, does not need a large amount of reagents, and is green and environmentally friendly; 2) the structure of thewood is reserved well, and the mechanical property is relatively excellent than before; 3) the treated wood has relatively high light transmittance and haze; and 4) the percentage of the energy storage material accounts in the resin composite material prepared by the method is up to 80%, so that the wood has a relatively good energy storage function, room-temperature regulation can be facilitated,and energy is saved. The invention aims to solve the problem that an existing light-transmitting wood material has no energy storage function.

Description

technical field [0001] The invention relates to a preparation method of a light-transmitting wood energy storage material. Background technique [0002] With the continuous increase of energy consumption along with economic development, energy saving and emission reduction are imminent. To solve this problem, a lot of research work is devoted to improving the efficiency of energy usage, reducing energy consumption and reducing the consumption of conventional energy sources. Therefore, reducing energy consumption in the construction industry has become a research hotspot. If we can utilize the inexhaustible and inexhaustible energy to the extreme, we can greatly reduce energy consumption. Light-transmitting buildings can replace artificial light sources with sunlight, which has a great positive effect on reducing energy consumption. [0003] The advantages of wood as a biomass material in terms of its renewable and environmental friendliness are gaining increasing attentio...
