Problems solved by technology

The main problems of the existing gypsum board materials are that the strength is not high, easy to be damaged, the moisture resistance is weak, and the mechanical strength is obviously reduced after being damp.
[0004] In the prior art, phase-change energy storage materials have been compounded in gypsum boards. However, most of the existing phase-change materials use ceramics, which are inorganic porous materials, as adsorption materials. Ceramics have limited porosity and weak adsorption capacity. Leakage of phase change material causing liquid phase

Description

technical field [0001] The invention belongs to the technical field of production of wall decoration materials, and in particular relates to a method for manufacturing a phase-change energy storage wall decoration board material. Background technique [0002] As my country vigorously promotes the development policy of building energy conservation and environmental protection, as well as the development of the construction industry and the innovation of wall materials, the application of building gypsum as a non-load-bearing wall material is becoming more and more extensive. The reason is that compared with traditional building materials, gypsum raw materials have the advantages of wide sources, easy preparation and low energy consumption, and are recognized as energy-saving and emission-reducing building materials. Gypsum board is used as a wall material for its environmental protection, humidity control, heat preservation, fire prevention, comfort and convenient constructio...
