Abstract

The invention relates to an ash calcium board, which is in a board shape and comprises the following raw materials in part by weight: 60 to 90 parts of calcium sulfate, 5 to 30 parts of ash calcium powder, 1 to 15 parts of siliceous raw material, 0.5 to 2 parts of starch, 0.2 to 2 parts of polyvinyl alcohol raw material, 0.3 to 5 parts of cellulosic raw material, 0.2 to 5 parts of aid, 3 to 15 parts of silicon ash, 2 to 4 parts of expanded perlite filler and 0,5 to 2 parts of glutinous rice flour. The ash calcium board has the advantages of light weight, high strength, fire prevention, moisture prevention and mildew prevention, no deformation after being soaked in water for 30 days, no mildew and unchanged inherent structural strength; the ash calcium board can absorb carbon dioxide indoors for a long time and clean indoor air; and the ash calcium powder is converted into calcium carbonate substances under the action of carbon dioxide, so that the strength of the product is enhanced, the service life is prolonged, and the ash calcium board is convenient to install and construct like a gypsum plaster board.

Description

Technical field [0001] The invention relates to an indoor and outdoor decorative board used in the construction industry, especially a gray calcium board. Background technique [0002] At present, the decorative boards that have been used in the construction field mainly include: calcium silicate board, magnesium oxide board, and gypsum board. Among them, calcium silicate board is characterized by waterproof, fireproof and high strength. Its shortcomings are high density, insufficient light weight, high hardness and not easy to break, inconvenient decoration and construction, and high damage rate; magnesium oxide board is characterized by waterproof and fireproof , High strength, etc., its shortcomings are that the density is not light enough, the hardness is not convenient for decoration and construction, and it is easy to return halogen, which seriously affects the use effect; the characteristics of gypsum board are light weight, convenient installation and construction, and it...
