Abstract

The invention relates to the technical field of building materials and in particular to a white marble gypsum board and a preparation method thereof. The provided white marble gypsum board comprises the following raw materials in parts by weight: 60-80 parts of gypsum powder, 10-20 parts of white marble sand, 8-15 parts of lime powder, 4-8 parts of kaolin, 8-16 parts of kieselguhr, 6-10 parts of plant straw, 5-10 parts of glass fibers, 1-3 parts of modified starch, 0.5-1.2 parts of a retarder, 1-2 parts of a water reducing agent, 0.3-0.5 part of a foaming agent, and a suitable amount of water.The invention further provides the preparation method for the white marble gypsum board. The white marble gypsum board prepared by the invention has the characteristics of high strength, good fireproof performance, and strong adsorbing effect, and is capable of eliminating an indoor peculiar smell, is high in practicability, environment-friendly, and extensive in usage.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a white marble 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 new type of interior decoration material introduced in the market in recent years. It is widely used in the material industry and 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., for indoor use should not be installed in the bathroom or kitchen. [0003] At present, the common gypsum boards on the market have low strength, single function, and low practicability, which have increasingly become obstacles affecting their use and development.
