Problems solved by technology

[0007] 4. High rigidity
[0023] In wine, beverage, and food packaging, glass, metal, and ceramic containers are usually subjected to high-temperature sterilization and disinfection by boiling for 30 minutes before filling (for example, Red Bull metal cans must be sterilized by boiling water for more than 30 minutes before filling). In the advanced thermal transfer printing process, the interface force between the adhesive layer and the surface of the material to be transferred is only van der Waals force, which is not enough to resist the invasion of water molecules at high temperature, so the water boiling resistance is generally poor, and the problem of image and text falling off often occurs
[0024] It is not feasible to apply the water-resistant treatment method of screen printing to thermal transfer printing. Usually, the coupling agent is added to the screen printing ink in advance and stirred evenly, and then the ink is printed on the glass within a specified time. On the surface of the container, the small molecules of the coupling agent in the ink will quickly migrate to the interface between the ink and the glass. Because the coupling agent contains both organic and inorganic double-group structures, it is between the ink (organic) and the glass (inorganic). Form a strong chemical bond between them, resulting in better water boiling resistance, but the ink mixed with the coupling agent has a short effective life, and use beyond the effective life will affect the performance

Embodiment （1）

[0055] Embodiment (1): Water-resistant surface treatment is carried out on flat glass. figure 1 The process of the embodiment (1) of the present invention is shown in the form of a process flow module, figure 2 for figure 1 top view. refer to figure 1 with figure 2 , as described below.

[0056] Flat glass (1-1) advances in the direction of the arrow on the production line (1-8).

[0057] Step 1, degreasing. The flame processor (1-2) ejects a high-temperature gas flame (1-3). When the flat glass (1-1) passes by, the grease on the glass surface is burned by the flame; the flame processor generally uses flammable gas (such as natural gas or liquefied petroleum gas) mixed with a combustion-supporting gas (such as air or oxygen) to generate a high-temperature flame. Existing products on the market, such as Rapidflame from the UK and Web Flame treatment from Enercon, have the advantage of a wide range of flame treatment.

[0058] Step 2, activate. The high-pressure spray ...

Embodiment （2）

[0061] Embodiment (2): A water-resistant surface treatment is performed on a cylindrical glass container. image 3 The process of embodiment (2) of the present invention is shown in the form of a process flow module, Figure 4 for image 3 top view. refer to image 3 with Figure 4 , as described below.

[0062] The cylindrical glass container wine bottle (2-1) advances in the direction of the arrow on the production line (2-10).

[0063] Step 1, degreasing. The jet plasma processor (2-2) ejects low-temperature plasma (2-3), and when the wine bottle (2-1) passes under the jet plasma processor (2-2), it stops briefly, and the wine bottle (2-1) Rotating 360° with the axis as the center line, the grease on the surface of the bottle is decomposed and gasified under the action of plasma high-energy particles; It can reach 10cm; for ordinary bottles, two rotating plasmas (2-11) can be superimposed to complete the treatment at one time. The existing products on the market are ...

[0071] Embodiment (3): Preparation of activation solution

[0072] Weigh 98g of deionized water, add 0.6g of fumaric acid as a pH adjuster and stir evenly to reduce the pH of the system to about 4.00; add 1g of coupling agent Dow Corning Z-6121, stir evenly and add substrate to wet The dose of Digo wet 250 is 0.4g.

[0073] Sample (1): Glass Transfer

[0074] Prepare a glass sheet sample of 10cm*10cm*0.1cm; use the process described in Example (1) and the activation solution described in Example (3) to carry out surface treatment on the sample; use epoxy system as the adhesive layer The flower film is transferred to the surface of the above sample by a thermal transfer machine; it is finally baked at 150°C for 30 minutes and then tested.

[0075] Sample (2): Glass printing

Abstract

The invention relates to a surface treatment method for improving the water resistance, and a treatment solution thereof. The method and the treatment solution are suitable for glass, ceramic, metal and other special substrates. The method comprises the following steps: A) deoiling: removing oil stains and dusts on the surface of a printing stock; B) activating: coating the surface of the printingstock with an activating solution; C) knifing: scraping the activating solution on the surface of the printing stock with a scraper to form an extremely thin water film; and D) drying: drying the activating solution on the surface of the printing stock. The method overcomes the defects of easy shedding and poor water boiling resistance of decorating pictures and texts on the surface of glass, ceramic, metal and other special substrates in packaging printing, and also can be applied to the fields of electronic packaging and composite materials.

Description

technical field [0001] The invention relates to a surface treatment method for improving water resistance and its treatment solution, which is suitable for the surface of special substrates such as glass, ceramics, and metals, and solves the problem that the decorative graphics on the surface of such substrates in packaging and printing are easy to fall off in a humid environment and are water-resistant. The defect of poor cooking performance, and the process can also be applied to electronic packaging, composite materials and other fields. Background technique [0002] Glass, ceramics, and metal are important construction and packaging materials, such as art glass, ceramic tiles, aluminum ceilings, etc., are widely used in the field of building materials, and glass wine bottles, glass perfume bottles, ceramic wine bottles, metal cans, etc. are widely used in packaging field. [0003] Taking glass as an example, as a packaging material, glass has a series of very valuable c...
