Abstract

The invention relates to a water-proof coating for an exterior wall and a preparation method thereof. The water-proof coating for the exterior wall comprises the following components in parts by weight: 70-85 parts of acrylate emulsion, 3-5 parts of tung oil, 15-20 parts of titanium dioxide, 15-20 parts of Portland cement, 3-5 parts of ethylene terpolymer, 5-10 parts of kaolin, 5-10 parts of hollow glass beads, 3-5 parts of wood fiber, 1-2.5 parts of a dispersing agent, 0.5-1 part of a defoaming agent, 0.5-1 part of a leveling agent, 1-3 parts of a water-proof agent and 15-25 parts of water. The water-proof coating for the exterior wall is plump, flat, and uniform in state after coating, has very high weather resistance, acid resistance, alkali resistance and low temperature resistance, is high in adhesion strength, has rain-proof, water-proof and moisture-proof effects, and is suitable for the exterior wall.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a waterproof coating for exterior walls and a preparation method thereof. Background technique [0002] Paint is a continuous film that is coated on the surface of a protected or decorated object and can form a firm adhesion with the object to be coated. It is usually based on resin, oil, or emulsion, with or without adding pigments and fillers. It is a viscous liquid prepared with organic solvent or water by adding corresponding additives. [0003] On the existing building exterior walls, a layer of paint is usually applied to achieve the purposes of thermal insulation, waterproof and mildew proof. Exterior wall coatings can protect the exterior walls of buildings that have been exposed to wind, sun and rain for years, and the walls are cracked and easy to fall off. Therefore, it must have good enough water resistance, weather resistance and stain resistance to be able to Guaranteed to...
