Display glass printing technology and refrigerator door shaping method using finished products formed thereby

Abstract

The invention discloses a display glass printing technology, comprising the following working procedures of: S2, printing low-temperature printing ink on one surface of a glass sheet and then putting the printed glass sheet into a drying channel for drying; S3, printing preset patterns on the glass sheet on the surface printed with the low-temperature printing ink; S4, printing a ground color on the glass sheet on the surface printed with the patterns via a screen printer and then putting the glass sheet into the drying channel for drying; and S5, printing a protective color on the glass sheet on the surface printed with the ground color via the screen printer and then putting the glass sheet into the drying channel for drying. The invention also relates to display glass obtained through the technology and a refrigerator door shaping method using the display glass. The display glass printing technoogy and the refrigerator door shaping method using finished products formed thereby in the technical scheme of the invention can directly foam the low-temperature printing ink and realize a frameless design of the refrigerator door so that the area of the display glass is maximized.

Description

technical field [0001] The invention relates to a color crystal glass printing process, in particular to a color crystal glass printing process using low-temperature ink and a refrigerator door foam molding method for a finished color crystal glass obtained by using the process. Background technique [0002] At present, colored crystal glass has been more and more used in the production and processing of household appliances. When it is used as a refrigerator door panel, the polyurethane foam material used in the foam molding of the refrigerator door will produce High temperature and high pressure, and the polyurethane foam will generate a strong pulling force when it is cooled, which makes it difficult for the low-temperature printing ink to adhere to the original glass sheet, which will easily lead to watermarks, paint peeling and other defects. [0003] In the prior art, the industry mainly adopts the following two methods for the above problems: [0004] One method is t...

AI Technical Summary

Problems solved by technology

The cost of this method is low, but because there is basically no cohesive force between the polyethylene film and the polyurethane foam material, there must be a mechanism to fix the color crystal glass around the glass so that the glass can be fixed on the refrigerator door. Firstly, the coverage area of ​​the color crystal glass is limited, and the frame design of the refrigerator door cannot be realized
