In order to make the present invention clearer, the present invention will be further described with reference to the accompanying drawings.
In the prior art, the industrial standard of the self-repairing hard coating is the standard of the self-repairing hard coating issued by the industry and informatization department, and the standard number is HG/T5675-; for example, a common self-repairing hardened film is formed by applying a coating liquid in which an elastomer, a polyurethane resin, an initiator and a solvent are mixed in a certain ratio. Wherein the initiator is one of 1-hydroxycyclohexyl phenyl ketone, 2-methyl-1- (4-methylthiophenyl) -2-morpholinyl-1-acetone, (2,4, 6-trimethyl benzoyl) diphenyl phosphine oxide, tolidine and 2-hydroxy-2-methylphenyl propane-1-ketone, and the solvent is a water-alcohol mixed solvent or an ester-ketone mixed solvent. Specifically, 20 parts of elastomer, 40 parts of polyurethane resin, 3 parts of initiator and 1 part of solvent. The self-repairing hardened film is formed by coating a coating liquid formed by mixing polyurethane acrylate in a monomer, an initiator, an auxiliary agent and a solvent according to a certain proportion, wherein the monomer adopts an acrylic resin monomer, the initiator adopts one of 1-hydroxycyclohexyl phenyl ketone, 2-methyl-1- (4-methylthiophenyl) -2-morpholinyl-1-acetone, (2,4, 6-trimethylbenzoyl) diphenyl phosphine oxide, tolidine ketone and 2-hydroxy-2-methylphenyl propane-1-ketone, and the solvent is a water-alcohol mixed solvent or an ester-ketone mixed solvent; the auxiliary agent adopts a flatting agent, and specifically comprises 30 parts of urethane acrylate, 1.5 parts of a monomer, 5 parts of an initiator, 10 parts of an isolation auxiliary agent and 53.5 parts of a solvent. The self-repairing hardened film has good ductility and peristalsis, and when the film is scratched, the self-repairing hardened film can well fill the scratch through the peristalsis performance of the self-repairing hardened film, so that the scratch is reduced or disappears; the self-repairing hardened film has high hardness and good wear resistance, and scratches are not easy to generate.
