Gypsum plaster board based on modified BPO (Benzoyl peroxide) fiber and preparation method thereof

Abstract

The invention discloses a gypsum plaster board based on modified BPO (Benzoyl peroxide) fiber, which comprises protective surface paper and a gypsum board, wherein the gypsum board comprises the following raw materials in parts by weight: 36-42 parts of gypsum powder, 22-28 parts of modified BPO fiber, 15-19 parts of polished tile waste slag powder, 6-10 parts of baryta feldspar, 5-9 parts of Suxian County clay, 3-5 parts of sodium bentonite, 2-5 parts of hydroxyethyl cellulose and 12-16 parts of deionized water. The protective surface paper comprises the following raw materials in parts by weight: 32-36 parts of pulp, 5-9 parts of ammonium octamolybdate, 4-8 parts of silicon carbide and 2-5 parts of micro powder graphite. The invention aims to provide the gypsum plaster board based on themodified BPO fiber. The gypsum plaster board has high strength, meanwhile, fireproof performance is further improved, and therefore, the gypsum plaster board has a high use value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of paper-faced gypsum boards, in particular to a modified BPO fiber-based paper-faced gypsum board and a preparation method thereof. Background technique [0002] Paper-faced gypsum board is made of building gypsum as the main raw material, mixed with appropriate amount of additives and fibers as the board core, and made of special cardboard as the protective surface. The paper-faced gypsum board has light weight, sound insulation, and insulation It has the characteristics of strong thermal and processing performance and simple construction methods. Because the paper-faced gypsum board has light weight, fire prevention, sound insulation, heat preservation, heat insulation, and good processability (can be planed, nailed, and sawed), convenient construction, and detachable. It has the advantages of good installation performance and increased usable area, so it is widely used in various industrial buildings and...

[0003] The existing Chinese patent document (publication number: CN107542214A) discloses a pressure-resistant and anti-folding type gypsum board, which belongs to the technical field of building materials, and mixes waste paper pulp, glass fiber, water-retaining materials, additives, modified starch and fillers. , to obtain the original slurry, move the original slurry into the storage tank for later use, stir and mix the desulfurized gypsum powder and water, add the original slurry, and continue stirring to obtain the slurry, inject the slurry into two layers of modified face paper , the gypsum board wet board is obtained by extrusion molding. After the gypsum board wet board is solidified, cut, dried, and sawed, a pressure-resistant and anti-folding paper-faced gypsum board is obtained. The intermolecular force between the glass fiber and other materials Poor, which in turn leads to poor performance
