Abstract

The invention discloses an optical-thermal double-solidified baikeding for a tinplate and a coating method thereof. The optical-thermal double-solidified baikeding comprises the following materials in parts by weight: 20-30 parts of polyurethane acrylate resin, 5-8 parts of epoxy acrylate resin, 30-50 parts of rutile titanium dioxide, 15-25 parts of activated monomers, 3-6 parts of photoinitiators, 2-4 parts of thermal initiators, 2-5 parts of pigment wetting agents, 0.5-1.5 parts of adhesion promoters, 0.5-1 part of substrate wetting agents, 0.3-0.5 part of leveling agents and 0.3-0.5 part of defoaming agents. According to the method, the baikeding is obtained by utilizing optical-thermal double solidification. The optical-thermal double-solidified baikeding disclosed by the invention has the advantages of completeness in solidification, high solidification efficiency, energy conservation, environment friendliness, good paint film friability, good impact force resistance, high adhesive force and high-temperature boiling resistance, and thus a product is more reliable and convenient when in use and has good production application prospect.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to a white coating for tinplate that is double-cured by ultraviolet light and heat, in particular to a white cured white coating for tinplate that is dual-cured by light and heat and a coating method thereof. Background technique [0002] Tinplate is a modern commonly used packaging material, mainly used in the production of food packaging tin boxes and cans, because tinplate combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in one Among the materials, it has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility. Before tinplate is used as a packaging material, it is generally printed to meet specific use requirements. As a necessary preparation before printing, a layer of white paint needs to be applied to the tinplate for subsequent printing. This paint is called white. Ke Ding. ...
