Abstract

The invention discloses a preparation method of a pure biomass-based temperature control material, which belongs to the field of new energy materials. In the present invention, periodate is firstly used to oxidize the surface of the high-yield pulp fiber with abundant resources and low price to form pores to increase its specific surface area, and then conduct a pore-forming process with a biomass-based organic phase change material with a melting point in the range of 26-35°C. Mechanically stirring and blending to obtain a pure biomass-based temperature control material suitable for human living environment requirements. The invention has wide sources of raw materials, relatively low cost, simple production process, good temperature control effect and long service life of the product, and can be applied to new energy-saving buildings on a large scale to create greater economic and social benefits, which is in line with the utilization of new technologies and Basic new materials are required for upgrading traditional industries and converting old and new kinetic energy.

Description

technical field

[0001] The invention relates to a preparation method of a pure biomass-based temperature control material, which belongs to the field of new energy materials. Background technique

[0002] In recent years, with the rapid development of the economy and the improvement of people's living standards, people have higher and higher requirements for thermal comfort in office and living environments, resulting in large building energy consumption (air conditioning, heating, ventilation, etc.) and greenhouse gas emissions. increase in magnitude. It is estimated that global building energy consumption accounts for about 30-40% of total human energy consumption. In order to solve these problems, new high-efficiency and energy-saving technologies are extensively explored. Among these solutions, phase change energy storage materials are considered to be one of the most promising passive energy storage methods due to their advantages of large energy storage capacity, con...
