Crack-resistant gypsum board

Abstract

The invention belongs to the technical field of building decorative materials, and particularly relates to a crack-resistant gypsum board. The crack-resistant gypsum board includes base plates, wherein uniformly distributed arc-shaped grooves are formed in the faces, facing the outer sides, of the base plates, and uniformly distributed cavities are formed in the base plates; arc-shaped plates corresponding to the arc-shaped grooves are connected between adjacent arc-shaped grooves in an inserted mode; the arc-shaped plates are used for strengthening the strength of the base plates; and baffles are arranged on the sides, away from the base plates, of the arc-shaped plates in a covering mode; I-shaped airbags are connected between the adjacent base plates; and the outer surfaces of the airbags are bonded to the end surfaces of the baffles, and the airbags are used for closely connecting the adjacent two base plates while pressing the baffles. According to the crack-resistant gypsum board, the arc-shaped grooves are formed in the sides, facing the outside sides, of the base plates, then the arc-shaped plates are connected into the arc-shaped grooves in an inserted mode to enable the adjacent arc-shaped grooves to be connected one another through the arc-shaped plates, when the base plates are integrally pre-bent, the corresponding support can be carried out to reduce the bending amplitude of the base plates, and thus the crack resistance of the base plates is enhanced, and the service life of the base plates is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, in particular to a crack-resistant gypsum board. Background technique [0002] 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.

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.

[0003] Especially in some areas where there is a lot of mining, blasting is often required during mining, so severe vibrations will be generated, and the gypsum board itself is made of lightweight materials, which has poor crack resistance, and because of excessive mining, it is easy to Earthquakes and other natural disasters will cause damage to the decoration in the building. For this environment, it is necessary to develop a gypsum board with strong crack resistance; accordingly, the present invention proposes a crack-resistant gypsum board. plate
