Embodiment 1-8

[0052] The plasma generator spray guns with the power of annular plasma flow of 1000W, 850W, 750W and 650W were used to plasma treat the concave surface of the curved glass plate, and the surface water droplets on the concave surface after plasma treatment were measured at different distances and moving speeds. contact angles and are recorded in Table 1. The distance in Table 1 refers to the distance between the torch of the plasma generator and the concave surface of the curved glass sheet.

Abstract

The present invention relates to the technical field of glass surface treatment, in particular to a method for cleaning the surface of automotive glass, and specifically provides a method for surface treatment of a curved glass plate suitable for coating a sol-gel coating, which includes the following steps: S1, preparing a convex surface and a curved glass plate with a concave surface; S2, using at least one annular plasma flow to perform plasma treatment on the convex and / or concave surface of the curved glass plate, and the surface water droplet contact angle of the convex or concave surface after the plasma treatment is less than 10°. The invention can remove oil stains or organic pollutants attached to the glass surface, improve the wettability of the glass surface, and quickly treat the surface tension of the curved glass plate to more than 70mN / m (mN / m), thereby satisfying the subsequent functional coating Layer coating requirements; and can improve the processing speed while meeting the plasma treatment effect, and can adapt to curved glass plates of different shapes, sizes, and profiles.

Description

Technical field: [0001] The invention relates to the technical field of glass surface treatment, in particular to a surface cleaning method for automobile glass, and specifically provides a surface treatment method for a curved glass plate suitable for coating a sol-gel coating. Background technique: [0002] In order to make the automotive glass have the functions of blocking infrared rays, blocking ultraviolet rays, hydrophobicity, anti-fogging or anti-reflection, a sol-gel coating with specific functions can be formed on the surface of the glass plate by the sol-gel method, such as infrared blocking coating. , UV blocking coating, hydrophobic coating, anti-fog coating or anti-reflection coating. [0003] Before applying the sol-gel coating on the surface of the glass plate, it is necessary to thoroughly clean the surface of the glass plate, and even achieve the effect of wetting the surface of the glass plate, so that the surface tension of the glass plate can meet the re...
