Aqueous fluorine-carbon paint and method for making same

Abstract

The invention discloses a waterborne fluorocarbon coating, which comprises the following substances: 0.1 to 0.3 percent of cellulose; 0.3 to 0.6 percent of dispersant; 0.1to 0.5 percent of wetting agent; 0.1 to 0.3 percent of multi-functional additive; 0.1 to 0.3 percent of defoamer; 0.1 to 0.2 percent of preservative; 0.2 to 0.6 percent of antimildew agent; 1.0 to 4.0 percent of antifreeze; 1.0 to 3.0 percent of film forming additive; 0.3 to 0.6 percent of levelling agent; 0.3 to 0.6 percent of PU thickener; 16 to 25 percent of rutile titanium dioxide; 35 to 50 percent of waterborne fluorocarbon emulsion; the left is solvent deionized water, and the percentage is percentage by weight. The invention has advantages of environment protection, high weatherability, strong anti-contamination and anti-aging performance.

Description

technical field [0001] The invention relates to coatings, in particular to a water-based fluorocarbon paint for exterior walls and a preparation method thereof. Background technique [0002] Wall decoration materials can decorate and protect buildings, improve the durability of buildings and prolong their service life. Due to the rapid development of the construction industry and the improvement of people's living standards, modern decorative materials in my country have also developed rapidly. At present, the materials used for exterior wall decoration at home and abroad mainly include decorative stone, glass curtain wall, exterior wall facing brick, various decorative panels, architectural coatings, etc. According to the characteristics and development trends of exterior wall decoration materials at home and abroad, my country's foreign Environmentally friendly high-performance exterior wall coatings should be the main development direction for wall decoration materials.

AI Technical Summary

Problems solved by technology

The current fluorocarbon paint is mainly solvent-based, and because the solvent-based fluorocarbon paint contains high VOC, the solvent is directly volatilized in the air during construction and cannot be recycled, resulting in waste of resources, polluting the environment, and has certain harm to the construction workers. Toxic, construction tools are difficult to clean

In addition, the paint film of solvent-based fluorocarbon paint is dense, poor in air permeability, and easy to form local bubbles

On the other hand, the weather resistance, stain resistance and aging resistance of latex paint in the prior art can not meet the needs of use
