Waterproof and mildew-proof gypsum board

Abstract

The invention discloses a waterproof and mildew-proof gypsum board. The waterproof and mildew-proof gypsum board is prepared from, by mass, 50-55 parts of gypsum powder, 8-14 parts of fine sand, 12-16 parts of wood fiber, 7-10 parts of fiber glass filaments, 5-9 parts of acrylic emulsion, 15-20 parts of an inorganic aluminum salt waterproof agent, 5-7 parts of aluminum oxide clay, 3-5 parts of magnesium oxide, 9-11 parts of a nano-zinc oxide fungus-proof agent, 4-8 parts of polyamide resin and 35-40 parts of water. The waterproof and mildew-proof gypsum board is good in water resistance, high in strength and fungus-proof capability and capable of preventing mildewing and blackening caused by inlet water.

Description

technical field

[0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a waterproof and mildew-proof gypsum board. Background technique

[0002] Gypsum is an air-hardening cementitious material, which 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. After that, its strength will be significantly reduced, and it will easily become moldy and black, which will affect the appearance. Contents of the invention

[0003] In order to solve the above existing problems, the present invention provides a waterproof and mildew-proof gypsum board with good water resistance, high strength and strong antibacterial ability, which can prevent mildew and blackening due to water ingress.

[0004] The technical solution adopted by the present invention to solve the above-ment...
