Abstract
The invention relates to the technical field of phase change heat storage materials and preparation methods, and especially relates to an organic phase change heat storage material. The organic phase change heat storage material comprises, by weight, 80-97 parts of an organic phase change material, 1-15 parts of an oxidation inhibitor, 1-5 parts of a thickening agent, 1-5 parts of a nucleating agent and 0.1-5 parts of an enhanced heat conduction material. A preparation method of the organic phase change heat storage material comprises the following steps: heating, stirring and melting the organic phase change material, adding the oxidation inhibitor, the thickening agent, the nucleating agent and the enhanced heat-conducting material, and uniformly stirring and mixing to obtain the organic phase change heat storage material. The problems that in the prior art, the organic phase change material serves as an energy storage main body material, oxidation is prone to occurring, and the heat conductivity coefficient is relatively low are solved, the supercooling and phase separation phenomena of the organic material are effectively prevented by selecting proper materials and proportions, and good cycle stability is shown; and the organic phase change heat storage material also has the advantages of strong oxidation resistance and good thermal conductivity.
