Description

technical field [0001] The invention relates to the technical field of wall coatings, in particular to an exterior wall coating with waterproof and excellent adhesion performance and a preparation method thereof. Background technique [0002] Paint, traditionally known as paint in China. The so-called 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, oil, or emulsion, with or without adding pigments, fillers, adding Corresponding additives, viscous liquid prepared with organic solvent or talcum powder. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coa...
