Description
Technical Field
The invention relates to a coating, in particular to a water-based coating with good durability and weather resistance.
Background
Coatings (including paints) are applied to the surface of an object to be protected or decorated and form a continuous film which is firmly attached to the object to be coated. The definition of the coating from the coating technology book which is relatively authoritative in the Chinese coating world is as follows: the paint is a material which can be coated on the surface of an object by different construction processes to form a continuous solid film with firm adhesion and certain strength. The film thus formed is generally called a coating film, also called a paint film or a coating. "
The water-based paint has good environmental protection performance, but has certain difference in functionality compared with the traditional solvent-based paint. The development of water-based coatings is one of the important directions for the development of water-based coatings. Durability is particularly important for architectural coatings, including weatherability, stain resistance, water resistance, alkali resistance, water resistance, and the like. The coating is exposed in the atmosphere all the year round, is subject to climate change all the year round, and is easy to crack, pulverize, discolor, bubble, drop, stain and the like under the external action of cold, heat, oxidation, humidity and the like, so that the original decorative effect and protective function of the coating are lost.
