Abstract

The invention provides a method for coating an ultraviolet-resistant bright and transparent composite coating. The primer varnish used in the invention is acrylic varnish, and the finishing varnish is one of trifluorofluorocarbon varnish or tetrafluorocarbon varnish. The composite coating is used on metal, carbon fiber composite materials or glass fiber composite materials to form a bright and transparent coating that can show the color of the metal body and the fabric texture of the composite material, and the composite coating film has high hardness, beautiful appearance, and Excellent weather resistance against heat and humidity, mold and UV rays.

Description

technical field [0001] The invention relates to a method for coating a composite coating, in particular to a method for coating a bright and transparent composite coating with ultraviolet resistance on metals, carbon fiber composite materials or glass fiber composite materials. Background technique [0002] Transparent coating can show the surface texture and body color of the substrate. As people have higher and higher requirements for product appearance, many products need to be sprayed with transparent coating to improve the appearance of the product, and metal and carbon fiber / glass fiber composite materials are no exception. The resins used in carbon fiber composites and glass fiber composites generally use epoxy resins. According to literature reports, resin systems containing epoxy structures have poor UV resistance, and the chain segments are easily decomposed under ultraviolet light. If the appearance of this kind of composite product is to adopt a transparent coati...
