Water-based environment-friendly single-component waterproof coating and preparation method thereof

Abstract

The invention discloses a water-based environment-friendly single-component waterproof coating and a preparation method thereof. The coating comprises a polymer emulsion, polyvinyl acetate resin, ammonia water, organic silicon acrylic resin, glass fibers, a preservative, a thickening agent, an antioxidant and water, wherein the coating coats a latticed grid which is fixedly connected to a surfaceneeding to be coated. The preparation method comprises the following steps: weighing the organic silicon acrylic resin, the glass fibers, the polymer emulsion, the polyvinyl acetate resin, the ammoniawater, a coalescing agent, the preservative and the thickening agent, and stirring the weighed materials in a main reaction kettle to obtain the finished product coating. The latticed grid is fixed on the surface needing to be coated in advance, and then the coating coats the latticed grid, so that the risk of coating cracking is prevented to the maximum extent. Meanwhile, the organic silicon acrylic resin and the glass fibers are adopted in the coating disclosed by the invention, so that overall strength of the coating surface can be enhanced, and capability of dissipating energy by bendinginstead of fracturing is improved.

Description

technical field [0001] The invention relates to a water-based environment-friendly one-component waterproof coating and a preparation method thereof, in particular to a water-based environment-friendly one-component waterproof coating with good coating effect and good waterproof performance and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. However, some existing coatings will peel off after being used for a period of time, thereby greatly affecting the coating waterproof effect of the coating. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water-based environmentally frie...
