Abstract

The invention provides a urethane acrylate oligomer, which comprises the following components: hexamethylene diisocyanate, propylene glycol methyl ether acetate, a hydroxyl-terminated fluorine compound, hydroxypropyl-terminated polydimethylsiloxane, polyethylene glycol, hydroxyl-terminated acrylate, etc. According to the invention, silicon and fluorine are introduced in the urethane acrylate oligomer, so that the urethane acrylate oligomer has high hydrophilic angle; and in addition, by means of high hydrophilia provided by ethyoxyl in polyethylene glycol, the urethane acrylate oligomer has high pollution-resistant property. The invention further discloses a preparation method of the urethane acrylate oligomer, which is simple in process and convenient for industrialization production. The invention simultaneously discloses a coating comprising the urethane acrylate oligomer, which comprises urethane acrylate oligomer and the like; after the coating disclosed by the invention is cured by ultraviolet light, the hydrophilic angle of a paint film is up to 100-120 degrees; the coating has excellent pollution-resistant property; and stain of an oily pen can be wiped cleanly without any trace.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a polyurethane acrylate oligomer, a preparation method thereof and a coating prepared therefrom. Background technique [0002] Polyvinyl chloride (PVC) plastic floor coil is a kind of floor covering material. It is made of polyvinyl chloride and its copolymer resin as the main raw material, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added. The base material is produced by extrusion process, and is widely used in hospitals, laboratories, office buildings, sports venues, gymnasiums, clubhouses and other places. The floors in these occasions are required to be easy to clean and take care of, so the floors are required to have excellent The anti-fouling function, the technology commonly used now is to coat a layer of anti-fouling paint on the surface of the PVC coiled plastic floor, and the paint film obtained after the paint is cured has the effect of...
