Abstract

The invention relates to a water-based fluorocarbon coating, which comprises the following components in terms of mass percentage: 20-85% of fluorocarbon emulsion; 5-20% of titanium dioxide; 1-31% of filler; 0.1-2% of auxiliary agent; 0.1-0.3%; film-forming aid 0.01-10%; thickener 0.01-1.1%; the rest is water. Compared with the prior art, the water-based fluorocarbon coating provided by the present invention greatly improves the strength, toughness and ductility of the coating emulsion due to the use of nano-silica-modified core-shell structure fluorocarbon emulsion, and at the same time, can Significantly improve the wear resistance, water resistance, weather resistance, anti-fouling, anti-corrosion performance of water-based fluorocarbon coatings, improve its transparency, reduce the minimum film forming temperature, and have broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to water-based fluorocarbon coatings. Background technique [0002] In the field of coating industry, solvent-based coatings contain a large amount of volatile organic solvents (VOC), which are discharged into the atmosphere during use, which not only damages the atmospheric environment, but also causes waste of resources. Fluorine coatings refer to various coatings with fluorine-containing resin as the base material. The fluorine-containing resin aqueous dispersion composition is formed from the fluorine-containing resin aqueous dispersion, and appropriate pigments, fillers, etc. are added according to the application. In addition to coating materials obtained by coating processes such as penetration coating, dip coating, and spray coating, they are also used in various applications such as cast films, plastic additives, fibers, and soil conditioners. The fluorine-containing wate...
