Embodiment 1

[0026] It is preferred to produce 10 parts of α high-strength gypsum from natural gypsum, 90 parts of β gypsum powder from natural gypsum, and 5 parts of ceramsite. After fully mixing, add 10 parts of gypsum fiber, stir well and set aside, then add 2 parts of foaming agent, Mix 0.1 part of starch and 0.1 part of retarder and put them into the measured aqueous solution, then add the mixed gypsum and ceramsite powder to obtain a uniform gypsum slurry, and pour the gypsum slurry evenly to 2100×600× Inside the 100mm plaster model (the length, width and thickness can be adjusted freely), after the plaster model solidifies and hardens. Curing and drying, cutting and finishing into multifunctional and assembled wallboard materials.

Embodiment 2

[0028] It is preferred to produce 20 parts of α high-strength gypsum from natural gypsum, 80 parts of β gypsum powder from natural gypsum, and 15 parts of ceramsite. After fully mixing, add 1 part of gypsum fiber, stir well and set aside, then add 1 part of foaming agent, Mix 5 parts of starch and 1 part of retarder and put them into the measured aqueous solution, then add the mixed gypsum and ceramsite powder to obtain a uniform gypsum slurry, and pour the gypsum slurry evenly to 2100×600× Inside the 100mm plaster model (the length, width and thickness can be adjusted freely), after the plaster model solidifies and hardens. Curing and drying, cutting and finishing into multifunctional and assembled wallboard materials.

Embodiment 3

[0030] It is preferred to produce 50 parts of α high-strength gypsum from natural gypsum, 50 parts of β gypsum powder from natural gypsum, and 30 parts of ceramsite. After fully mixing, add 6 parts of gypsum fiber, stir well and set aside, then add 5 parts of foaming agent, Mix 0.1 part of starch and 0.1 part of retarder and put them into the measured aqueous solution, then add the mixed gypsum and ceramsite powder to obtain a uniform gypsum slurry, and pour the gypsum slurry evenly to 2100×600× Inside the 100mm plaster model (the length, width and thickness can be adjusted freely), after the plaster model solidifies and hardens. Curing and drying, cutting and finishing into multifunctional and assembled wallboard materials.

Abstract

The invention discloses a preparation method of a prefabricated multifunctional gypsum wallboard. The method comprises the following steps: mixing alpha gypsum powder and beta gypsum powder in a certain mass ratio, and then adding ceramsite; fully dissolving a foaming agent, starch, a retarder and the like in water, then adding the mixed gypsum and the ceramsite to the water, and stirring the mixture to obtain uniform gypsum slurry; pouring the gypsum slurry into a preset mold, and performing casting molding, curing drying and finishing to prepare the prefabricated wallboard. The preparation method is simple, easy to operate, and particularly suitable for infill walls, partition boards, lintel plates, door pocket plates and the like of mid-high rise frame structures in the construction industry; the product has wide application range, has good heat preservation and fire resistance, and can completely avoid risks of open flame combustion and the like.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing an assembled multifunctional gypsum wallboard. 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. 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. [0003] At present, there are many boards sold in the market, including cement blocks, concrete slabs, gypsum blocks, thermal insulation laminates, external wall thermal insulation laminates, gypsum boards, etc. With the promotion of high-rise building frame construction, t...
