Problems solved by technology

However, the currently used acrylic latex paints are uneven due to the performance of the selected emulsions. Some emulsions have poor water resistance, and the price limit makes them poor in weather resistance, hydrophobicity, and chloride ion penetration resistance. Conducive to long-term effective protection of concrete

Abstract

The invention relates to a waterborne fluorine silicone resin modified acrylic acid concrete protective coating. The concrete protective coating comprises 10-20 parts of a fluorine emulsion, 20-40 parts of a silicone resin emulsion, 10-20 parts of a soap-free pure acrylic emulsion, 5-10 parts of sericit, 5-15 parts of talcum powder, 5-1 parts of ground calcium carbonate, 0.5-1.0 part of a dispersing agent, 0.05-0.2 part of a pHregulator, 0.3-0.5 part of a defoaming agent, 1.0-2.5 parts of propylene glycol, 0.5-2 parts of an antifungus and anti-mildew agent, 0.5-1.0 part of a thickening agent, 1.0-2.5 parts of a film-forming agent, 1.0-5.0 parts of a water repellent agent, 0.3-0.5 part of a flatting agent, 0.1-0.3 part of a tank bactericide and 30-45 parts of deionized water. The waterborne fluorine silicone resin modified acrylic acid concrete protective coating has the beneficial effects of weatherability, alkali resistance, washability, air permeability and mildew resistance. The concrete protective coating has a long-term protective effect for the concrete.

Description

technical field [0001] The invention belongs to coatings, in particular to a water-based fluorosilicone resin modified acrylic concrete protective coating. Background technique [0002] Because the concrete structure is used in many occasions, such as the ground, the inner and outer walls of the building, storage tanks, underground pipelines, concrete bridges, concrete dams, etc. Therefore, there are many types of coatings that can be used on concrete surfaces. However, some coatings are not suitable for use on concrete surfaces. For example, after alkyd resin coatings are in contact with highly alkaline concrete surfaces, the fatty acid groups are saponified so that the coating film is quickly destroyed. At present, there are several types of coatings for concrete surface protection: epoxy coatings have good adhesion to concrete surface epoxy coatings, and have excellent chemical resistance. Epoxy coatings are currently the most important type of coatings for heavy-duty a...
