Abstract

The invention discloses an inorganic coating with air purification and antibacterial functions and a preparation method of the inorganic coating. The coating is prepared from the following ingredients in percentage by mass: 8%-20% of nanometer titanium dioxide, 5%-18% of nanometer zinc oxide, 5%-17% of infrared ceramic powder, 7%-15% of white diatomite, 15%-30% of water glass, 3%-10% of white conductive powder, 3%-10% of white tourmaline powder and 1%-20% of inorganic pigment, with the balance being water. The inorganic coating is easy to prepare, firm in combination, high in stability, friendly to environment, durable and resistant to corrosion, has antibacterial and mildew-resistant effect, can efficiently remove volatile organic compounds such as formaldehyde and benzene series in air, achieves excellent air purifying effect, and can be widely applied to decoration materials.

Description

Technical field: [0001] The invention relates to the technical field of functional coatings, in particular to an air-purifying and antibacterial functional inorganic coating and a preparation method thereof. Background technique: [0002] At present, due to the emission of volatile organic compounds (including formaldehyde, benzene series, hydrocarbons, halogenated substances, etc.) from decoration and building materials, furniture, paint, workpiece adhesives, and office equipment, the indoor air quality is greatly reduced. [0003] Air-purifying coatings can be coated on surfaces such as walls, decorative materials, ornaments, vases, etc., and absorb and degrade organic volatiles, and are widely used in the field of indoor air purification. At present, the air-purifying paints on the market all contain organic components, and the active ingredients in the paint may decompose the organic components, causing the film layer to fall off, powder falling, and secondary air pollut...
