Water-based alkali resistant paint

Abstract

The invention provides a water-based alkali resistant paint, which comprises the following raw materials by weight: 40-60 parts of an organosilicon modified pure acrylic emulsion, 50-70 parts of water-based unsaturated polyester acrylate resin, 40-60 parts of waterborne polyurethane resin, 10-15 parts of triethylenetetramine, 11-14 parts of a film-forming assistant, 9-15 parts of a defoaming agent, 7-9 parts of a curing agent, 20-28 parts of an alkali-resistant emulsion, 10-13 parts of hydroxyethyl cellulose, 8-10 parts of a formaldehyde absorbent, 12-16 parts of titanium dioxide, 12-16 parts of talc powder, 18-25 parts of a pure acrylic emulsion, 2-4 parts of a preservative, and 30-40 parts of water. The water-based alkali resistant paint provided by the invention can adsorb formaldehyde and purify air, does not cause harm to human health, and is suitable for internal and external brick walls and the like. The paint contains alkali-resistant component, at the end of construction, the paint film has good effect, and efflorescence and floating are unlikely to appear, thus effectively preventing wall alkali efflorescence. Also, the water-based alkali resistant paint has strong adhesion and low VOC.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a water-based alkali-resistant coating. Background technique [0002] With the enhancement of human awareness of environmental protection, various countries have successively formulated environmental protection regulations on VOC (volatile organic compound) emissions, and the emission standards have become increasingly strict, aiming to encourage the promotion of new products that are green, environmentally friendly, energy-saving and emission-reducing. The anti-alkali primer is composed of materials such as anti-alkali emulsion. Alkali-resistant coatings mainly play a good sealing role. It has strong adhesion to concrete, outstanding alkali resistance and sealing performance, and is compatible with various floor coatings and protective coatings for concrete structures. However, the anti-alkali sealing coatings commonly used in the market are often unable to achieve the desired effect d...

Problems solved by technology

However, the anti-alkali sealing coatings commonly used in the market are often unable to achieve the expected effect due to the unreasonable formula components and poor sealing effect, especially the lack of water-based anti-alkali coatings.
