Problems solved by technology

[0003] There are two main types of existing humidity control coatings: one is powder humidity control coatings, which are not easy to operate, and the dust is extremely harmful to the human body
The other is latex paint, which uses organic synthetic resin as the main base material, and is made with other additives and pigments; however, due to its large amount of organic components, it is difficult to avoid the smell, and it needs to add more Bactericides are used for antibacterial; and because it is physically attached to the surface of the contact object, the adhesion to some rough clay or mineral material surfaces is poor, and the paint film is easy to peel off

Abstract

The invention relates to the technical field of a coating, and in particular relates to an inorganic silicate conditioning paint. The inorganic silicate conditioning paint comprises 15-25% of silicate, 0.1-0.5% of defoaming agent, 0.1-0.5% of wetting dispersant, 1-5% of negative ion release agent, 0.1-0.5% of cellulose, 20-25% of porous aggregate, 0.01-0.02% of charcoal powder, 5-10% of styrene-acrylic emulsion, 0.1-0.3% of thickener and the like calculated according to the weight percent. The substances in the formula are added at different time and prepared into the product under the control of different agitating speeds. The inorganic silicate conditioning paint is environment-friendly, can achieve the situation that no smell or formaldehyde is detected, does not contain alkylphenol ethoxylates (APEO), contains ultra-low volatile organic compounds (VOC), can absorb and decompose the formaldehyde, can maintain fresh air for a long period of time, is especially good in antibacterial property and not easy to burn, and can be applied to hard substrates such as coarse clay or mineral material surfaces.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an inorganic silicate moisture-adjusting coating and a preparation method thereof. Background technique [0002] Inorganic water-based silicate coatings have long been used in bridges, ships, offshore oil facilities, various storage tanks and steel rust prevention projects in advanced countries such as Europe, America and Japan. Moreover, because this product can directly produce chemical cross-linking properties with cement, when used in cement buildings, its adhesion, physical properties, and chemical properties are also superior to organic coatings. [0003] Existing humidity-controlling paints are mainly divided into two types: one is powder humidity-controlling paints, which are not easy to operate, and the dust is extremely harmful to the human body. The other is latex paint, which uses organic synthetic resin as the main base material, and is made with other additives an...
