Embodiment 1

[0045] A method for removing film from the edge of coated glass, comprising the steps of:

[0046]1) Pretreatment of the original glass: the original glass is obtained through pretreatment processes such as cutting, edging, cleaning, drying, and loading;

[0047] 2) Masking treatment: Apply low-temperature pyrolysis ink to the area of ​​the original glass surface that does not need to be coated by screen printing process (such as figure 2 2 regions shown);

[0048] 3) Drying and curing treatment: drying the low-temperature decomposition ink on the original glass at a temperature of 95°C to make it solidify;

[0049] 4) Cleaning and coating treatment: On the surface of the original glass coated with low-temperature pyrolysis ink, use the magnetron sputtering coating method to coat the required film layer (the coated film layer is located at figure 2 Middle 1 area);

[0050] 5) Subsequent processing process: the original glass is made into a finished product through powder ...

Abstract

The invention discloses a method of removing a film from edge of coated glass. The method at least comprises the following steps: 1) carrying out mask coating treatment on a region, without needing to coat the film, of glass to be coated by adopting low-temperature thermal decomposition ink; 2) carrying out drying and solidification treatment on the glass to be coated, which is treated in the first step; 3) carrying out magnetron sputtering coating treatment on the glass to be coated, which is obtained in the second step; and 4) carrying out powder spraying, matching, hot bending, cleaning, laminating, high pressure and packaging treatments on the glass obtained in the third step. A coated glass product prepared by the film removing method is beautiful in side boundary and reliable in quality and is suitable for edge film removing process of automobile glass.

Description

technical field [0001] The invention relates to the technical field of coated glass coating, in particular to a method for removing film from the edge of coated glass. Background technique [0002] Coated glass is widely used in building doors and windows and automobile windows because of its special functions such as sunshade, thermal insulation, and rich colors. However, the film layer prepared by off-line coating technology (such as magnetron sputtering) is not as good as that prepared by online coating The film layer is dense, and the film layer of off-line coating is easily corroded or scratched, resulting in the failure of the functional film, especially for low-emissivity (Low-E) coated glass, whose main functional film is silver, and the silver film is particularly easy to oxidize in the air. In order to avoid the low-emissivity Low-E film of off-line coating from contacting with air, water, etc., after the coating is completed, the coated glass is generally removed ...
