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.
