Problems solved by technology

[0006] Since the UV coating is engraved with radium, the wear resistance of the white coating needs to meet the wear resistance requirements of the UV specification, which meets the characteristics of high wear resistance of the computer keyboard itself. This kind of white wear-resistant coating has become a future. Development trend, the existing white paint can no longer meet the requirements of high wear resistance

Abstract

The invention discloses a highly wear resistant white coating for computer keyboards. The white coating contains thermoplastic acrylic resin, hydroxy acrylic resin, a diluent, a dispersant, titanium dioxide, polytetrafluoroethylene wax powder, wax liquor, a silicon dioxide thickening agent and a leveling agent. The highly wear resistant white coating for computer keyboards is reasonable in composition, has good component coordination and excellent comprehensive properties, has viscosity suitable for spraying and good storage property, can meet the wear resistance requirement of products under the thickness of 12-16mu m, without increasing the usage amount of the wear resistant fillers and the like, is suitable for the computer keyboard UV post-laser carving process and gains unexpected technical effects.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a highly wear-resistant white coating for computer keyboards, which can be used for computer keyboards and solves the problem of the wear resistance of white coatings after UV radium engraving. Background technique [0002] The existing white coatings for computer keyboards on the market are traditional products with poor wear resistance (512 rubber resistance: 500g*200 times), in order to meet the wear resistance requirements (512 rubber resistance: 500g*1000 times) all It is produced by the traditional method. The traditional process is white font spraying → shading black spraying → laser engraving → matte UV spraying, that is, laser engraving before UV, so that the wear resistance of the UV coating can be tested to meet the wear resistance requirements of computer keyboard coatings. . [0003] Existing white paint products are used in traditional production processes. After ...
