Problems solved by technology

The above-mentioned fire-proof sound-absorbing heat insulation board and light-weight fire-proof sound-absorbing decorative board contain magnesium oxide and magnesium chloride, so there will be a phenomenon of halogen return during use. Permanent damp stains will cause its strength to decrease, the surface of the paint layer to fall off, and some buildings are even uninhabitable. In addition, the foaming agent, modifier, waterproofing agent, etc. contained in the material will cause environmental pollution, which is harmful to the occupants. adverse effects on the health of
The manufacturing method of the above-mentioned light-weight fire-proof and sound-absorbing decorative board not only has many raw materials, but also has complicated process steps and a long production cycle.
[0004] The patent application with the publication number CN101428999A discloses a diatomite decorative sound-absorbing board and its preparation method. Since this board contains gypsum and fiber materials, and the preparation method is to stir the solid material evenly and then add water to make a slurry, Then the slurry is poured into the mold, cured for 24 hours, demoulded, and dried, so the refractoriness is low, and toxic and harmful gases will be released in the fire, which does not meet environmental protection requirements, and the moisture absorption is serious, and there is a phenomenon of powder and slag falling during use.
[0005] The patent application with the publication number CN101234873A discloses a vitrified microbead heat insulation and sound insulation board and its manufacturing method. Because this kind of heat insulation and sound insulation board contains cement, mixed fibers and redispersible latex powder, etc., and the preparation method is to mix the water-containing mixture After rolling evenly, let it stand for 5-8 hours, and then dry it at 25 ° C ~ 40 ° C, so the refractoriness is low, and toxic and harmful gases will be released in the fire, and there will be moisture absorption and moisture return, which does not meet environmental protection requirements
