Preparation method for self-illumination wood capable of simultaneously storing heat energy and light energy

Abstract

The invention discloses a preparation method for self-illumination wood capable of simultaneously storing heat energy and light energy, relates to a preparation method for the energy-storage self-illumination wood, and aims to solve the problem that the wood capable of simultaneously storing heat energy and light energy cannot be prepared at present. The method comprises the following steps: 1, dipping the wood into mixed solution of sodium hydroxide and sodium sulfite, heating to the boiling point, and washing to obtain delignify wood; 2, dipping the delignify wood into hydrogen peroxide solution to be bleached to obtain the bleached wood; 3, mixing rare earth aluminate illumination materials with a molten phase change material to obtain the mixture of the rare earth aluminate illumination material and the phase change material, dipping the bleached wood into the mixture of the rare earth aluminate illumination material and the phase change material to be kept, and obtaining the self-illumination wood capable of simultaneously storing heat energy and light energy. The invention discloses the preparation method for the self-illumination wood capable of simultaneously storing the heat energy and the light energy.

Description

technical field [0001] The invention relates to a method for preparing energy-storing self-luminous wood. Background technique [0002] Due to the continuous reduction of non-renewable energy sources such as fossils, and the intermittent nature of new energy sources such as solar energy, wind energy, and tidal energy, it cannot meet the growing needs of people. And people's energy consumption in terms of light energy and heat energy accounts for nearly 50% of the total consumption, so the development of energy storage materials that can store heat energy and light energy is becoming more and more important in the process of energy application and development. Phase change energy storage materials have attracted extensive attention because of their good thermal storage capacity. At present, many researchers are focusing on the preparation of phase change energy storage composite materials. For example, Beijing Institute of Technology has prepared smart fibers with energy sto...
