Abstract

The invention belongs to the field of novel material research and development, and particularly relates to an efficient phase-change energy storage composite, and preparation and application thereof.The phase-change energy storage composite is prepared from the following components in parts by weight: 10-50 parts of sodium sulfite, 5-20 parts of a hardening agent, 40-70 parts of crystalline wax,10-25 parts of water, 1-4 parts of a curing agent; 0.5-1.0 part of dibenzoyl peroxide, and 0.5-1.0 part of dibutyltin diacetate. The phase-change energy storage composite has the advantages of suitable phase-change temperature, large thermal conductivity and high energy storage density.

Description

technical field [0001] The invention belongs to the field of research and development of new materials, and in particular relates to a high-efficiency phase-change energy storage composite material and a preparation method thereof. Background technique [0002] Composite materials can be a combination of inorganic energy storage materials, a combination of organic energy storage materials, or a combination of organic energy storage materials and inorganic energy storage materials. After theoretical research and practical development, the energy storage characteristics of various materials are still obvious. For example, the characteristics of energy storage of inorganic materials: wide range of use, large thermal conductivity, large heat of fusion, high energy storage density, generally neutral, cheap, etc. At the same time, supercooling is easy to occur, that is, the substance does not crystallize when it is condensed to the "condensation point", but it needs to reach a ce...
