Coating with high weatherability and self repairability

Abstract

The invention provides coating with high weatherability and self repairability. In the invention, monomer optical solidification resin is added into a paint system and is sprayed or brushed to form a film after being dispersed evenly, and the coating with higher weatherability and self repairing performance is obtained. The adding weight of the monomer optical solidification resin is 0.5-5% of that of the basal body resin of the paint system. The invention utilizes the combined action of the ultraviolet light of sunlight and oxygen in air, uses the optical solidification resin to absorb part of the ultraviolet light so as to delay the aging of the coating, utilizes the ultraviolet light causing the aging of the coating as an excitation signal, promotes the optical solidification resin added in the coating to generate an optical solidification reaction on the surface layer of the coating for forming novel coating, prohibits the aging destruction of the coating, enhances the weatherability and realizes the self repairability of the coating.

Description

technical field [0001] The invention relates to a high weather resistance and self-repairing coating used for decoration and anticorrosion of outdoor equipment, equipment and structures, and belongs to the technical field of chemical coatings. Background technique [0002] Coating is a solid continuous film obtained by coating. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. Generally, the coating obtained by the paint is relatively thin, about 20-50 microns, and the thick build-up coating can obtain a coating with a thickness of more than 1 mm at one time. [0003] Coating is one of the oldest technologies in human history, and it is also the most important and common means of decoration and protection in the atmospheric environment. However, organic coatings generally contain a certain amount of photosensitive impurities or components in the atmospheric environment. Through these Th...
