Composite inorganic hydrous salt phase-change material and preparation method of inorganic composite phase-change plate
The invention relates to the field of composite building and ornament materials, in particular to a composite inorganic hydrous salt phase-change material and a preparation method of an inorganic composite phase-change plate. The preparation method comprises the steps that the pre-configured composite inorganic hydrous salt phase-change material raw materials comprising 100 parts of magnesia powder, 10-30 parts of clay powder, 15-25 parts of slag powder, 6-25 parts of Al2O3 padding, 45-60 parts of composite sulfate, 10-32 parts of wood flour, 0.5-1 part of composite phosphate, 5-7 parts of perlite, 75-85 parts of water and 0.2-1 part of citric acid are provided; the raw materials are mixed and evenly stirred into mixed slurry; the mixed slurry is compounded with glass fiber cloth to form an inorganic composite heat accumulation panel. The inorganic composite phase-change plate has the advantages of being low in weight and high in strength, saving energy, preserving moisture, resisting water, being good in toughness, absorbing sound, being environmentally friendly and high in ornamental performance and the like, meanwhile, has the high energy storage density and low degree of supercooling, is free of layering and good in stability, has impermeability, and does not corrode metal.
