Abstract
The invention relates to a high-gloss, high-hardness, easily-scrubbed and scrubbing-resistant metal material. The metal material comprises a base plate and a protective coating formed on the base plate, wherein ultraviolet (UV) curing paint is used by the protective coating; the raw material formulation of the UV curing paint comprises the following components by weight percent: 15-25% of epoxy resin, 35-45% of a UV monomer, 30-40% of yellowing-resistant resin, 1-5% of a photoinitiator, 0.1-1.5% of a flatting agent, 0.1-1.5% of a defoaming agent and 0.5-3% of anti-fouling material. The protective coating of the metal material has smooth hand feel, and is high in hardness and scratch-resistant. When a metal material is used for a writing board, the writing board has bright and full surface and is excellent in erasable property; the anti-fouling material is added into the formulation of the patient, so that whiteness residue and coloring are not easily caused by watermarks during writing, and the writing board has better writing performance and better sustainable wiping property.
Description
technical field [0001] The invention belongs to the field of color-coated plates, and in particular relates to a high-gloss, high-hardness, easy-to-clean, and scrub-resistant metal material. Background technique [0002] The existing writing board adopts PCM board (three-coated and three-baked paint galvanized cold-rolled sheet), which has the following defects: low gloss, generally above 35 (GB28231-2011); short wiping cycle, use water-based pen to write When using water-based pens, watermarks and color residues will appear; the polyester paint film is soft, and the surface is deformed when writing, and there will be blanks when wiped; the polyester paint is dried and cured, and the cross-linking voids are large, resulting in water-based ink penetration and color residues when writing; the paint film is soft, Large surface voids also result in poor resistance to wiping. Contents of the invention [0003] The technical problem to be solved by the present invention is to o...
