Problems solved by technology

CN1436825A talks about adding a wear-resistant additive accounting for 0.5-3% of the total weight in the coating system. The type of this wear-resistant additive is BYK920, which is a reactive auxiliary agent that can improve the cross-linking effect of resins or diluting monomers. Therefore, the wear resistance of the cured paint film can be increased to a certain extent, but it is difficult to increase the hardness and wear resistance of the paint film to a large extent at the same time, so it cannot meet the requirements for the use of portable plastic device coatings

Abstract

The present invention relates to one kind of ultraviolet cured paint for plastics and its production process. The paint includes matrix resin, active diluent, light initiator and solvent and features its antiwear hardness additive accounting for 0.1-8.0 wt% of the paint. The paint has high hardness, high antiwear performance, forms smooth paint coating through spraying, high toughness, high adhesion and high chemical corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an ultraviolet curing coating for plastics and a manufacturing method thereof, in particular to an ultraviolet curing coating for plastics with high hardness and wear resistance. Background technique [0002] UV-curable coatings have the characteristics of high efficiency, energy saving, no pollution, wear-resistant paint film, high hardness, strong adhesion, and corrosion resistance. They have been widely used in furniture coating, home decoration, and inks. Due to the above-mentioned characteristics of UV-curable coatings, it is currently being applied to the topcoat of plastic accessories for portable devices, such as the surface of mobile phone casings, laptop computer casings, and cosmetic packaging casings. Spraying this kind of plastic parts with UV-curable paint can make it tough and wear-resistant, resistant to sweat or other chemicals, high gloss, and long service life. ...
