Problems solved by technology

Compared with other water-based varnishes, water-based fluorocarbon varnish has lower surface tension and better hydrophobicity after film formation, so it has better stain resistance, but it is not as good as oil-based varnishes; oil-based varnishes have poor water vapor permeability

Abstract

The invention discloses a waterborne fluorocarbon texture coating and a preparation method and application thereof. The coating comprises the following components in part by weight: 141 to 180 parts of fluorocarbon emulsion, 5 to 12 parts of film-forming aid, 5 to 6 parts of cosolvent, 80 to 100 parts of water, 1 to 2 parts of antifoaming agent, 3 to 6 parts of disinfectant, 1 to 3 parts of mildew preventive, 2 to 3 parts of pH regulator, 5 to 10 parts of thickening agent, 600 to 1,000 parts of color sand, and 0 to 89 parts of sheet. The preparation method comprises the following steps of: under the stirring at a high speed, adding the film-forming aid, the cosolvent, the antifoaming agent, the disinfectant, and the mildew preventive in turn, stirring at the high speed and reducing the stirring speed; adding the fluorocarbon emulsion, regulating the pH value, and regulating the viscosity by using the thickening agent to obtain pulp; stirring the pulp at a low speed, adding the color sand and sheet, and mixing to obtain the waterborne fluorocarbon texture coating. The waterborne fluorocarbon texture coating applied to a coated outer wall surface has good protection functions of water resistance, weather resistance, smudge resistance, and the like, and makes the wall surface have elegant, harmonious and serious aesthetic feeling.

Description

technical field [0001] The invention belongs to the technical field of water-based texture paint for exterior walls, in particular to a water-based fluorocarbon texture paint for exterior walls, a preparation method and application thereof. Background technique [0002] Water-based texture paint for exterior walls is a kind of exterior wall decoration paint that has a decorative effect similar to marble and granite, which has become popular in recent years. It is mainly made of natural colored sand or rock flakes of various colors. The buildings decorated with texture paint have natural and real natural color, giving people an elegant, harmonious and solemn aesthetic feeling, suitable for outdoor decoration of various buildings . Especially for decoration on curved buildings, it can be vivid and return to nature. Texture coatings are fireproof, waterproof, acid and alkali resistant, and pollution resistant. Non-toxic, odorless, strong adhesion, never fade and other charac...
