Problems solved by technology

[0004] At present, some composite phase change heat storage materials have been put into the market, but they have not been widely used in life and industry. The reason is that these phase change materials mainly have the following problems: there is no appropriate phase change temperature and phase change temperature. Latent heat, resulting in too narrow applications; large volume changes during the phase transition process, corrosion, and easy damage to containers; unstable kinetic properties, non-negligible sup

Abstract

The invention belongs to the technical field of phase change heat storage materials and discloses a supported type semi-cage type aquo-complex phase change heat storage material and a preparing method and application thereof. The phase change heat storage material is prepared from, by mass, 100 parts of water, 10-110 parts of tetraisoamyl quaternary ammonium salt and 0.01-20 parts of supporting materials. The supported type semi-cage type aquo-complex phase change heat storage material has the advantages of being stable in room temperature, proper in phase change temperature, large in phase change latent heat and large in heat conducting coefficient, the size changes little in the phase change process, supercooling and separation phenomena are avoided, chemical performance is stable, and the material can be applied to the field of phase change heat storage.

Description

technical field [0001] The invention belongs to the technical field of phase-change thermal storage materials, and in particular relates to a room-temperature-stable load-type semi-cage hydrate phase-change thermal storage material and its preparation method and application. Background technique [0002] In today's society, the increasingly severe energy and environmental situation has stimulated people's research on thermal energy utilization, and heat storage technology to solve the problem of time-space mismatch of heat supply has emerged as the times require. Phase change heat storage materials have extremely high heat storage density. During the process of phase change, they can absorb a large amount of heat from the environment and store them. When necessary, they can release heat from the environment, thereby improving the utilization rate of energy. Therefore, phase change heat storage materials have broad development prospects and are widely used in refrigeration an...
