Problems solved by technology

There are various plate and strip products on the market. Most of the existing gypsum is made of polyvinyl alcohol, glue and water mixed into paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material, so in It is used in some indoor environments that generate moisture and humidity. After a period of use, the gypsum board will loosen and fall off, which will damage the original shape and destroy the indoor beautification environment.

Abstract

The invention discloses a crack-resistant plasterboard. The crack-resistant plasterboard comprises, by weight, 12 parts of ore tailings, 42 parts of quicklime, 3 parts of iron oxide powder, 4 parts of fly ash, 14 parts of alumina silicate fibers, 10 parts of a silicon filling material, 4 parts of slag, 6 parts of a polymer emulsion, 6 parts of a calcium oxide expanding agent and 95 parts of water. The crack-resistant plasterboard avoids plasterboard cracking, does not contain formaldehyde, has no pollution, guarantees plasterboard strength and hardness and has good environmental protection functions.

Description

[0001] technical field [0002] The invention relates to the field of building materials used for interior decoration, in particular to crack-resistant gypsum boards. [0003] Background technique [0004] At present, with the improvement of people's living standards, most family houses are decorated with gypsum boards. Gypsum board is a lightweight, fire-resistant building decoration material, mostly used for indoor ceilings. There are various plate and strip products on the market. Most of the existing gypsum is made of polyvinyl alcohol, glue and water mixed into paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material, so in It is used in some indoor environments that generate water vapor and humidity. After a period of use, the gypsum board will loosen and fall off, which will damage the original shape and destroy the indoor beautification environment. Contents of the invention [0005] The purpose of the present invention is to pro...
