Problems solved by technology

[0003] The formula composition and production process of the current energy storage materials are unreasonable, resulting in poor crack resistance of the energy storage materials. When the ambient temperature is low, high or subjected to a large force, the energy storage materials are prone to cracking. Thereby affecting its energy storage effect, the service life is short, and brings greater trouble to the user

Abstract

The invention provides an anti-crack energy storage material and a preparation method thereof, and relates to the technical field of energy storage material production. The anti-crack energy storage material is prepared from the following raw materials in parts by weight: 55-65 parts of polyacrylamide, 18-22 parts of titanium dioxide, 12-16 parts of polypropylene fiber, 14-18 parts of phenyl-beta-naphthylamine, 10-14 parts of N,N-diphenyl p-phenylenediamine, 6-10 parts of N-phenyl N'-isopropyl p-phenylenediamine, 4-6 parts of a cross-linking agent, 2-4 parts of a dispersing agent, 2-4 parts ofa thickening agent, 2-4 parts of a stabilizer and 4 parts of a coupling agent. According to the invention, the defects of the prior art are overcome, and the continuity of the components in the energy storage material is effectively enhanced, so that the generation and development of the cracks of the energy storage material is effectively prevented, the generation of the cracks of the energy storage material is effectively prevented or delayed under static or dynamic conditions, the service life is long, and the material is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of production of energy storage materials, in particular to a crack-resistant energy storage material and a preparation method thereof. Background technique [0002] Phase change energy storage materials refer to a type of material that automatically absorbs or releases latent heat to the environment by using the phase state or structure change of the material itself within a certain temperature range, thereby achieving the regulation of the ambient temperature. The specific phase transition process is: when the ambient temperature is higher than the phase transition temperature, the material absorbs and stores heat to lower the ambient temperature; when the ambient temperature is lower than the phase transition temperature, the material releases the stored heat to increase the ambient temperature. For example, in winter, phase change energy storage materials absorb solar energy during the day and release he...
