Powerful-effect mould-proof and wall-surface decorative material which uses diatomite as filler

Abstract

The invention discloses a strong anti-mildew wall decoration material with diatomite as a filler. The raw materials in parts by weight include: 50-600 parts of diatomite, 50-250 parts of attapulgite, and 50-50 parts of sepiolite 250 parts, 50-250 parts of gypsum powder, 30-250 parts of talcum powder, 30-150 parts of magnesium hydroxide, 3-30 parts of hydroxyethyl cellulose, 30-250 parts of silica aerosol, 5 parts of zinc pyrithione ‑120 parts, 10‑100 parts of inorganic pigments. The invention regulates indoor humidity, sound insulation and heat insulation, absorbs indoor toxic gases such as formaldehyde, aromatic hydrocarbons, and methylene chloride, and is flame-retardant, smoke-eliminating, and anti-drip. The decorative material has stable physical and chemical properties, no fading, no fading, no corrosion, Environmental protection, antibacterial and anti-mildew features. The materials adopted in the invention are all natural and environment-friendly, the cost is reduced, the production procedure is simple, the color is natural, not dazzling, the environmental protection performance is higher, and the weak alkali does not irritate the skin.

Description

technical field [0001] The invention relates to the technical field of interior decoration materials, in particular to a strong anti-mold wall decoration material with diatomite as a filler. Background technique [0002] Diatom mud paint is a new type of functional wall decoration environmental protection material developed in recent years. Its main component is diatomite, which uses the porous structure of diatomite to absorb harmful gases in the air. Catalysis is used to decompose harmful substances such as formaldehyde in the air, and the advantages of lime calcium powder, such as water resistance, sterilization and mildew resistance, are used as auxiliary materials, and white cement is added as a cementitious material to bond materials to the wall. [0003] However, due to the poor adhesion between inorganic materials in the existing diatom mud, there are technical problems that the paint is easy to powder and fall off after the construction of the building wall.

Problems solved by technology

[0003] However, due to the poor adhesion between inorganic materials in the existing diatom mud, there are technical problems that the coating is easy to powder and fall off after the construction of the building wall. In order to solve this problem, organic glue is often added to the coating. , due to the strong odor of residual solvents of this kind of substances, it is easy to block the pores of diatomite, which reduces the environmental protection function of diatom mud coatings to a large extent. Paint durability is poor

In addition, this kind of wall material does not have the function of decomposing harmful gases such as formaldehyde. From the perspective of the development trend of diatom mud coatings, the development of multi-functional, high bonding strength and good durability diatom mud coatings will be the first choice for architectural decorative coatings. The future direction of the industry
