Abstract

The invention relates to a wear-resistant UV (ultraviolet) photocuring paint which is prepared from the following raw materials in parts by weight: 30-35 parts of high-functionality aliphatic polyurethane acrylic resin, 4-6 parts of brown fused alumina powder, 13-18 parts of 2-methyl methacrylate, 4-7 parts of isoprene, 5-9 parts of polylactic acid, 2-4 parts of sodium silicate, 2-4 parts of isopropyl thioxanthene ketone, 2-3 parts of liquid rosin resin, 3-5 parts of ricinoleic acid, 2-4 parts of propenyl glycidol ether and 4-6 parts of assistant. By adding the brown fused alumina powder, the wear resistance and flame retardancy of the UV (ultraviolet) photocuring paint are enhanced, and the cost of the paint is lowered; and the paint has the advantages of high crosslinking and curing speed, uniform film formation, high strength, favorable toughness, favorable water resistance and favorable binding property. The assistant enhances the dispersivity of the paint, so that the UV (ultraviolet) photocuring paint has favorable leveling property and the coating formed by the piant is smooth and bright.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a wear-resistant UV photocuring coating and a preparation method thereof. Background technique [0002] The advantages of light-curing coatings are short curing time (a fraction of a second to a few minutes), low curing temperature, and low volatile matter, which are energy-saving, resource-saving, pollution-free, and high-efficiency; but there are still some shortcomings, such as free radical type The curing process of light-curing coatings is inhibited by oxygen, poor surface curing, and a series of problems such as yellowing, explosive color, low temperature resistance, high cost, and poor corrosion resistance, all of which need to be continuously improved for different purposes to reduce production costs , to expand the use. Contents of the invention [0003] The purpose of the present invention is to provide a kind of wear-resistant UV light-cured coating and preparation method th...
