A kind of spraying method of fluorocarbon metal paint

Abstract

The invention discloses a spraying method of fluorocarbon metallic paint. The spraying method of the fluorocarbon metallic paint comprises the following steps that fluorocarbon metallic finish is sequentially sprayed onto a first surface, a second surface,..., and a nth surface of the surfaces of a workpiece, and n is a positive integer larger than 1; and fluorocarbon mixed varnish is sprayed onto one or more surfaces of the first surface, the second surface,..., and the nth surface of the surfaces of the workpiece. According to the spraying method of the fluorocarbon metallic paint, colors of coatings of all the decoration surfaces of the sprayed workpiece can be identical, and the color difference is much smaller than the international color difference range and meets the national standard; in addition, the reflection rates of the coating metal are basically identical; and furthermore, the spraying method is easy to operate and convenient to implement.

Description

technical field [0001] The invention relates to a spraying method, in particular to a spraying method of fluorocarbon metal paint. Background technique [0002] Fluorocarbon paint, also known as fluorocarbon paint, is a general term for paints that use resins containing F-C bonds as the main film-forming substance and organic solvents as the dissolution medium. Due to the strong bond energy of the F-C bond and the short distance, it has super long weather resistance and chemical medium corrosion resistance. Fluorocarbon paint is widely used in anti-corrosion coating of outdoor buildings. The main components of fluorocarbon paint are fluorocarbon resin, acrylic resin, pigment, organic solvent, and in order to increase the metal reflectivity of the coating, metal powder is added, such as bright silver aluminum powder and golden yellow copper powder. It is customarily called "metallic paint". [0003] The coating methods of fluorocarbon paints generally include roller coating...

AI Technical Summary

Problems solved by technology

[0004] The current general coating method of fluorocarbon paint (the number of decorative surfaces to be coated is ≥ 2) is: put the workpiece on the shelf after pretreatment → spray fluorocarbon primer on the front side → spray fluorocarbon primer on the reverse side → spray fluorocarbon fluorocarbon metal surface on the front side Paint→spray fluorocarbon fluorocarbon metal topcoat on the reverse side→spray fluorocarbon varnish on the front side→spray fluorocarbon varnish on the reverse side→cure→take off the shelf, but the front and back coatings of the coated workpiece after this method are prone to obvious visual color difference
