Abstract

The invention discloses a mothproof and fireproof glass fiber surface gypsum board and a preparation method thereof. Including the intermediate base layer made of gypsum cementitious material, the glass fiber surface formed by coating the outer side of the intermediate base layer with glass fiber mesh, and the contents of each component are parts by weight during batching: 1000 parts of hemihydrate gypsum powder; 30-35 parts; 20-45 parts of glass fiber; 75-90 parts of glass fiber mesh cloth; Moth-proof, fire-proof performance is higher than paper-faced gypsum board, belongs to Class A non-combustible material, and has better waterproof performance. It can be widely used in the fields of construction and decoration.

Description

technical field [0001] The invention relates to a building decoration board that can be used in the fields of construction and decoration, in particular to a mothproof and fireproof glass fiber-faced gypsum board and a preparation method thereof. Background technique [0002] At present, all sectors of society have higher and higher requirements for interior decoration. Users pay more and more attention to the performance of fire prevention, waterproof, and deformation resistance in terms of ceilings and partition walls. new material. A kind of decorative plate that is widely used now is plasterboard, the substrate of the plate is gypsum cementitious material, and the protective layer is paper. Most of the flexural strength of this paper-faced gypsum board comes from the strength of the protective paper. When the protective paper is damp, the flexural strength of the board will drop sharply. Moreover, the protective paper is flammable. In terms of non-combustibility, the p...
