Abstract

The invention discloses a high-strength gypsum board and a preparation method thereof, and relates to the technical field of novel building materials. The high-strength gypsum board comprises the following raw materials: modified gypsum powder, Zuoyun clay, anorthite powder, nano tourmaline powder, coarse whiting powder, borax, a silicon carbide fiber, p-hydroxybenzoic acid isopropyl ester, an organic silicon emulsion, a coupling agent, an anti-mold agent, a defoaming agent and an adhesive. The preparation method comprises the following steps: mixing raw materials, aging, performing injection molding, performing natural maintenance, demolding, drying, and shaping, thereby obtaining the high-strength gypsum board. The high-strength gypsum board is simple to prepare, and low in cost; and the problem that the conventional gypsum board is low in mechanical strength is solved, that is, the strength of the gypsum board is not greatly affected or even degraded even when the gypsum board is used in moisture and wet environments for a long time, so that the high-strength gypsum board is long in service life, safe, reliable and wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a high-strength 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, thinner thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. 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. The biggest shortcoming of these types of gypsum boards is the low mechanical strength, especially after a period of use in water vapor and humid i...
