Problems solved by technology

At present, there are various plate-shaped and strip-shaped products on the market. Most of the existing gypsum is made of polyvinyl alcohol, hide glue and water to form a paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material. , so when used in some indoor environments that generate water vapor and humidity, the gypsum board will become loose and fall off after a period of use, which will damage the original shape and destroy the indoor beautification environment

Embodiment Construction

[0011] specific implementation

[0012] The high-strength waterproof gypsum board involved in the present invention, its main raw material components and parts by weight are:

[0013] Component parts by weight Component parts by weight

[0014] Hemihydrate gypsum powder 100 Reticular polypropylene fiber Appropriate amount

[0015] Polymer Emulsion 10 Expanded Perlite 1

[0016] Glass Fiber 5 Magnesium Oxide 2

[0017] Calcium Oxide 3 Industrial Water 68

[0018] The specific preparation method is: uniformly mix various raw materials, pour them into the required mold, evenly spread the mesh polypropylene fiber in the gypsum slurry, vibrate, pressurize, remove the film and then maintain it. After 24 hours, an excellent high-strength waterproof gypsum board was obtained.

Abstract

The invention relates to a high-strength waterproof gypsum board, which is characterized in that the high-strength waterproof gypsum board consists of 100 weigh portions of semi-hydrated gypsum powder, a proper amount of reticulated polypropylene fiber, 10 weight portions of polymer emulsion, 1 weight portion of expanded perlite, 5 weight portions of glass fiber, 2 weight portions of magnesia, 3 weight portions of calcium oxide, and 68 weight portions of industrial water. The high-strength waterproof gypsum board has the following main characteristics that: 1) the gypsum board has high strength and long service life; 2) the gypsum board is dampproof and waterproof, and effectively prevents from loosening and falling; 3) the gypsum board has no toxicity and pollution, and cannot cause the harm to people and environment; and 4) the gypsum board has simple process and convenient operation.

Description

technical field [0001] The invention relates to the field of building decoration material manufacturing, in particular to a high-strength waterproof gypsum board. Background technique [0002] At present, with the improvement of people's living standards, most family houses are decorated with gypsum boards. Gypsum board is a lightweight, fire-resistant building decoration material, mostly used for indoor ceilings. At present, there are various plate-shaped and strip-shaped products on the market. Most of the existing gypsum is made of polyvinyl alcohol, hide glue and water to form a paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material. , so when used in some indoor environments that generate water vapor and humidity, the gypsum board will become loose and fall off after a period of use, which will damage the original shape and destroy the indoor beautification environment Contents of the invention [0003] The object of the present in...
