Abstract

The invention relates to an exterior wall paint, and concretely relates to an aqueous high weather resistance environmental protection fluorine carbon paint. The paint of the invention is a novel high weather resistance environmental protection fluorine carbon paint. A novel aqueous fluorine carbon resin which is adopted in the invention is subjected to a self-chemical crosslinking reaction to generate a high performance high weatherability macromoleclar polymer. The aqueous high weather resistance environmental protection fluorine carbon paint has the main characteristics of possessing of performances of a solvent-based paint, and solution of the possibility of auto-polymerization in a normal temperature state. The paint of the invention can be applied to the new construction of large building exterior walls, has an ultraviolet ray resistance and an erosion resistance to chemical substances in environment, and has a good adhesion with various types of substrates.

Description

technical field [0001] The invention relates to a fluorocarbon paint and a preparation method thereof, mainly water-based highly weather-resistant and environment-friendly fluorocarbon paint and a preparation method thereof. Background technique [0002] Fluorocarbon coatings refer to coatings with fluororesin as the main film-forming substance; also known as fluorocarbon coatings, fluorine coatings, fluororesin coatings, etc. Compared with traditional coatings, fluorocarbon coatings not only have excellent light resistance and weather resistance, but also have high surface hardness, impact resistance, buckling resistance, and excellent abrasion resistance. Light in weight during use, it will not increase the load on the surface of the object to be used, and the surface dust can also be automatically cleaned by rainwater. Fluorocarbon coatings have good adhesion to the surface of metals such as copper and stainless steel or composite materials during the coating process. M...
