Embodiment Construction

[0014] Moisture-proof gypsum board consists of the following raw materials in parts by weight: 23 parts of building material powder with a particle size of 48 μm, 503 parts of gypsum, 11 parts of wood fiber, 12 parts of expanded perlite, 11 parts of ground calcium carbonate powder, 4 parts of retarded Agent, 25 parts of water with a Ph value of 8.5, its specific preparation method carries out the following steps successively:

[0015] 1) Mix building material powder, wood fiber and gypsum and add water with 40% of the weight of gypsum at the same time, stir for 9 hours, and then put it into the aging warehouse for aging. The stirring speed is 850rpm, and the stirring time is 10h, and the water content is controlled at 6%. aging material;

[0016] 2) Add expanded perlite, heavy calcium carbonate powder, retarder, and remaining water to the aging material obtained in step 1), put it in a mixer, stir evenly, and transfer it to the green body mold for extrusion molding and mixing ...

Abstract

The invention discloses a moisture-proof plasterboard. The moisture-proof plasterboard is prepared from the following raw materials in parts by weight: 23 parts of building material powders with the grain diameter of 48 micron, 503 parts of plaster, 11 parts of wood fiber, 12 parts of expanded perlite, 11 parts of heavy calcium carbonate powders, 4 parts of a retarder and 25 parts of water with the PH value of 8.5. The wear-resistant and moisture-proof formula is added into the ingredients of the moisture-proof plasterboard, and building material powders and wood fiber are adopted as the raw materials to produce a decorative board which is formaldehyde-free and pollution-free; meanwhile, the recycle of plaster resources is realized, the strength and hardness of the plasterboard are guaranteed, and the plasterboard is good in moisture proofness.

Description

[0001] technical field [0002] The invention relates to the field of building materials used for interior decoration, in particular to moisture-proof gypsum boards. [0003] Background technique [0004] Gypsum board is widely used in building decoration materials because of its light weight, high strength, sound insulation, heat insulation, fire prevention, and easy processing. The wear resistance of gypsum board is average, and it is a direction of research in building materials, but its application range still needs to be developed. [0005] Contents of the invention [0006] The purpose of the present invention is to provide a moisture-proof gypsum board, adding wear-resistant and moisture-proof formula to the ingredients, using building material powder and wood fiber as raw materials to produce formaldehyde-free and pollution-free decorative boards, and at the same time realizing the reuse of gypsum resources, ensuring The strength and hardness of gypsum board hav...
