Gypsum board with air purification function and preparation method thereof

Abstract

The invention provides a gypsum board with air purification function. The gypsum board is characterized by being prepared from the following components by weight: 50-80 parts of desulfurized gypsum, 20-30 parts of rock wool, 15-25 parts of diatomite, 10-20 parts of shell powder, 3-5 parts of activated carbon, 1-3 parts of a waterproof agent, 0.3-0.8 part of a foaming agent, 0.1-0.5 part of a binder, 0.1-0.5 part of a photocatalyst, and 30-55 parts of water. The gypsum board provided by the invention has very strong fire resistance, long time stability in case of fire, environmental protection and no pollution, can effectively remove harmful gas, has greatly improved heat conduction coefficient, 2h water absorption thickness swelling rate, bending strength and other performance parameters, and is completely superior to similar products on the market, thus having good market prospects. The preparation process involved in the invention is simple and feasible, and can realize large-scale industrial promotion.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a gypsum board with the function of purifying air and a preparation method thereof. Background technique [0002] Gypsum board is widely used in various buildings such as residential buildings, office buildings, shops, hotels and industrial plants for interior partition walls, wall cladding panels (instead of plastering layers), ceilings, sound-absorbing panels, ground floor panels and various It is a building material such as a decorative board; compared with lime and cement, it has the advantages of light weight, high insulation strength, thinner thickness, and convenient processing. However, although the quality of gypsum board is lighter than lime and cement, it still belongs to the weight Higher materials increase the difficulty of transportation and installation of gypsum boards, and the consumption of raw materials is high and the cost is high; moreo...

AI Technical Summary

Problems solved by technology

[0005] The conventional gypsum boards currently sold in the market are ordinary paper-faced gypsum boards, water-resistant, fire-resistant, and moisture-proof gypsum boards, etc. The main features are stable size, smooth surface, good toughness, and non-combustibility. They are used for ceilings, partition walls, and interior wall veneers. , ceilings, sound-absorbing panels, etc., but has no effect on the removal of formaldehyde
