Abstract

The invention discloses an ultraviolet curing colored coating for a glass color mirror. The ultraviolet curing colored coating comprises an acrylic oligomer, a reactive acrylate monomer, a photoinitiator, pigments and aids. The coating is environmental-friendly, pollution-free and excellent in mirror leveling performance and can realize rapid UV curing coloring, and the cured coating has the characteristics of being flat in appearance, high in hardness, excellent in scratch resistance, high in adhesive force, excellent in plating property and the like. The invention further relates to a glasscolor mirror made by utilizing the coating and a making method of the glass color mirror.

Description

technical field [0001] The invention belongs to the technical field of radiation curing coatings, and in particular relates to an ultraviolet (UV) curing colored coating for colored glass mirrors and an application thereof. Background technique [0002] In addition to the function of the mirror, the colored glass mirror is also very decorative, so it is more and more popular among people. At present, the manufacturing method of the colored glass mirror is mainly to coat the baking-type colored coating containing solvent on one side of the glass, form the colored coating after curing and drying, and then plate metal coatings such as aluminum and silver on the surface of the colored coating. However, this method contains organic solvents, and VOC emissions are large, which will cause air pollution, which is not conducive to human health, and the curing and drying time of the coating is long, and the energy consumption is high. Contents of the invention [0003] Aiming at th...
