Problems solved by technology

[0006] In order to overcome the deficiency that existing ultraviolet (UV, ultraviolet) curable coatings and nano coatings cannot be reworked, the present invention provides a new method for surface coating rework, which can increase the surface tension of the surface coating and make the surface coating The layer is changed from hydrophobic to hydrophilic to improve the adhesion between the surface coating and the surface coating applied for rework, so that it is more suitable for practical use

Abstract

The surface re-coating process for some structure with one coated layer includes the first plasma treatment or corona treatment of the coated layer to convert the hydrophobic coating into hydrophilic coating, and subsequent re-coating. Owing to the conversion of original coating into hydrophobic coating, the re-coated layer may be well adhered to the original coating.

Description

technical field [0001] The present invention relates to a surface coating process, in particular to a surface coating rework method. Background technique [0002] Surface coating usually refers to a layer of material coated on the outermost layer of a product. Its functions can include surface modification, wear resistance, coating, modification, and even adding new features as required. At present, more attention-grabbing surface coating materials (or "coatings") include ultraviolet (UV, ultraviolet) curable coatings and nano coatings. [0003] UV-curable coatings are irradiated with short-wavelength ultraviolet rays to produce chemical reactions and overlap to produce three-dimensional bridging and hardening coatings. Because UV coatings do not contain volatile organic compounds, they have little environmental pollution, fast curing speed, energy saving, and good performance of cured products, so they are suitable for high-speed automatic production.
