Abstract

The invention relates to a metal material with sheet metal processing capability based on UV digital printing and surface photocureable coating treatment. The metal material comprises a substrate, a top coating arranged on the substrate and an ink layer formed on the top coating, wherein the raw material formula of a painting used in the top coating comprises the following ingredients: 48-52% of polyester resin, 1-3% of solvent naphtha, 1-3% of DBE, 0.3-0.5% of a wetting dispersant, 30-34% of titanium pigment, 1-3% of propylene glycol monomethyl ether acetate, 8-10% of cross-linked resin, 1-3% of polyethylene wax, 0.5-1% of a flatting agent, 0.5-1% of a catalyst and 1-1.5% of a functional accessory ingredient, wherein the functional accessory ingredient is one or a combination of several selected from polyacrylate modified polyester, 2-butoxy ethanol and di-ethylene glycol propylene glycol-methyl ether. According to the metal material, the functional accessory ingredient is added into the formula, so that the coating has favorable processing performance and chemical resistance, and has favorable adherence to printed ink.

Description

technical field [0001] The invention belongs to the field of color-coated plates, and relates to a metal material capable of sheet metal processing based on UV digital printing combined with surface photocuring paint treatment. Background technique [0002] Coating is a kind of chemical product with convenient construction, low price, obvious effect and high added value. It has excellent anti-corrosion performance, can prolong the service life of the coated object, and can also play a decorative effect to give people a beautiful enjoyment, such as commonly used in home appliances. With the development of the times, people have higher and higher requirements for the appearance of home appliances. Traditional coatings, that is, conventional single-color products, can no longer meet people's needs for the appearance of home appliances. The surface of the coating film with the surface color pattern can give people a rich color feeling, which is more and more in line with the ne...
