Inorganic phase change material with phase change temperature of 60 DEG C and preparation method of inorganic phase change material

Abstract

The invention discloses a preparation method of an inorganic phase change material with a phase change temperature of 60 DEG C. The method comprises the steps of mixing a certain amount of magnesium sulfate heptahydrate and a certain amount of sodium sulfafe decahydrate in a preparation dish, adding a certain amount of potassium sulfate and aluminum potassium sulfate dodecahydrate for uniform mixing at a certain temperature, adding a certain amount of anhydrous sodium carbonate, sodium allysulfonate and aluminum ammonium sulfate for uniform mixing a certain temperature, adding a certain amountof sodium octyl sulfate, aluminum ammonium sulfate and potassium nitroferrocyanide for uniform mixing at a certain temperature, and adding a certain amount of water for uniform stirring to form a mixture, namely the inorganic phase change material with the phase change temperature of 60 DEG C. The method has the benefits that the inorganic phase change material with the phase change temperature of 60 DEG C has the advantages of stable performance, high latent heat of phase change, no toxicity or corrosion and the like.

Description

Technical field [0001] The invention belongs to the technical field of preparation of phase change energy storage materials, and particularly relates to an inorganic phase change material with a phase change temperature of 60°C and a preparation method thereof. Background technique [0002] With the outbreak of the oil crisis in the 1970s, the application of thermal energy storage technology in the field of energy saving and new energy has received more and more attention, providing an effective solution to the energy problem in the world today. In the field of phase change energy storage, research and development of phase change materials with large latent heat, high cost performance and relatively stable performance are the core. Phase change materials are new energy storage materials that are environmentally friendly and energy-saving. When phase change occurs, they can absorb cold (heat) from the environment or release cold (heat) into the environment, thereby achieving the g...

Problems solved by technology

For example, after the phase change material has undergone multiple cooling and heating cycles, the mixture will undergo supercooling and phase separation, which will reduce the heat storage performance of the material.
