Abstract

The present invention is ultraviolet light cured paint for leather and leatherette. The ultraviolet light cured paint consists of: aliphatic polyuretheane acrylic ester 25-50 wt%, acrylic acid modified epoxy resin 0-20 wt%, reactive acrylic ester monomer 10-50 wt%, light initiator 5 wt%, leveling agent 0.3-1 wt%, defoaming agent 0.1-0.5 wt%, wetting agent 0.5-1.5 wt%, wear-resistant agent 0.5-3 wt% and solvent 2-20 wt%. The ultraviolet light cured paint for leather and leatherette of the present invention is white or milk white colloid liquid, has solid content of 80-98%, may be stored at room temperature and lightproof condition for one year, and has the features of curing at normal temperature, high production efficiency, forming film with excellent flexibility, high luster degree, high wear resistance, high corrosion resistance and high durability, etc.

Description

technical field [0001] The invention belongs to the coating for treating the surface of leather or artificial leather, in particular to an ultraviolet curing coating for leather or artificial leather. Background technique [0002] Traditional leather or artificial leather surface treatment as described in Chinese application number CN 85102368 is a class of monomers such as acrylate, chloroprene, acrylonitrile, styrene and acrylic acid copolymerized to make emulsion, and then by roller coating or It is sprayed on the surface of leather or artificial leather to treat it; another kind, as described in US Pat. But no matter which of the above-mentioned treatment technologies, there are low solid content and long drying time. If heated and baked, it will easily deform or even damage the leather or artificial leather material; the solvent resistance, alkali resistance and abrasion resistance of the coating have yet to be determined. improve. ...
