Abstract

The invention discloses an aqueous organic-inorganic composite coating, comprising the base materials of water-soluble film-forming material, pigment, filler, additive and water. The aqueous organic-inorganic composite coating is specifically composed of the following component, by weight: 15-25 parts of potassium silicate, 10-20 parts of styrene-acrylic emulsion, 0.2-0.5 part of stabilizer, 0.2-0.5 part of dispersing agent, 0.3-0.6 part of defoaming agent, 0.2-0.5 part of film-forming additive, 0.2-0.5 part of antifreeze, 0.1-0.3 part of thickening agent, 14-20 parts of titanium dioxide, 15-25 parts of heavy calcium, 5-10 parts of talcum powder and 20-25 parts of water. The invention has the following advantages: high film hardness, no cracking, excellent weather fastness, lasting replenished film, no addition of preservatives, excellent environmental protection performance, long recoating period of film and resource saving. In addition, the product has minimal construction resistance, and is easy for painting, promotion and application. The aqueous organic-inorganic composite coating has wide application range, and can be applied to coating of basement, underground parking, inner wall and outer wall.

Description

【Technical field】

[0001] The invention relates to the field of coatings, in particular to a water-based organic-inorganic composite coating and a preparation method thereof. 【Background technique】

[0002] With the improvement of people's living standards, people's demand for coating types is gradually increasing, and people pay more attention to the green environmental protection of products. For cement-based concrete exterior walls and basements, due to the strong alkalinity, high humidity and high hardness requirements of the walls, after ordinary latex paint is applied, it is prone to poor adhesion, low hardness, efflorescence, mildew and easy peeling And other disadvantages, not suitable for concrete base surface construction.

[0003] At present, there are few domestic coatings suitable for concrete base surface construction. Therefore, developing a coating with good film adhesion, high hardness, water resistance, alkali resistance, temperature change resistance, weat...
