Lightweight gypsum board and preparation method thereof

Abstract

The invention discloses a lightweight gypsum board. The lightweight gypsum board comprises a gypsum board main body, a gypsum board layer and an inner structure. The lightweight gypsum board and a preparation method of the lightweight gypsum board have the following advantages that 1, a fireproof layer is arranged in the gypsum board, structural decomposition or fracture can be prevented from being caused during burning, the fireproof performance of an overall structure is improved, meanwhile, a waterproof layer is arranged, water leakage or water seepage of the structure can be prevented being caused in overcast and rainy weather to influence the overall indoor aesthetic degree, and rainwater is prevented from infiltrating a room to pollute the inner part of the room; and 2, a shock cushioning layer is arranged on the inner structure to prevent tripods, supporting transverse plates and other structures on the inner part from losing supporting performance due to the fact that an outerstructure extrudes the inner part when the outer structure is extruded, an insulating layer is arranged to remain stable indoor temperature to prevent the indoor temperature from generating a large margin change, a sound absorption layer is arranged so that the external noise can be isolated, and a quiet and comfortable environment is provided for the inner part of the room.

Description

technical field [0001] The invention relates to the technical field of gypsum board building materials, in particular to a lightweight gypsum board and a preparation method thereof. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. [0003] Gypsum boards have been widely used in interior partition walls, wall cladding panels (replacing plastering layers), ceilings, sound-absorbing panels, ground floor panels and various Decorative panels, etc. At present, the gypsum boards on the market mainly include paper gypsum boards, decorative gypsum boards, and gypsum hollow strips. [0004] At present, these types of gypsum boards have the problem of high cost but poor strength, and are used in some...

AI Technical Summary

Problems solved by technology

[0004] At present, these types of gypsum boards have the problem of high cost but poor strength, and are used in some indoor environments that generate moisture and humidity. The waterproof performance of gypsum boards is very low, and water seepage often occurs, which makes the original Some shapes are damaged, and at the same time destroy the indoor beautification environment, and seriously affect people's lives. In addition, the current gypsum boards are not fireproof, and the internal structure tends to loosen and fall off after burning. very poor
