Description

Technical Field

[0001] This utility model relates to a glass panel with an inseparable color-changing layer, suitable for high-temperature or high-humidity applications, and providing different texture or background color effects. Background Technology

[0002] It is known that inorganic glass-based coatings impart specific surface qualities. The glass component of the coating, often referred to as glass frit or glass flux, gives the coating specific chemical and physical properties. These include, for example, chemical resistance, abrasion and scratch resistance, and thermal stability. Compared to coatings with organic matrices, inorganic coatings are notable for their higher gloss and greater resistance to UV radiation. By adding coloring pigments, antireflective additives, or matting additives, a wide range of possibilities are available for distinguishing and constructing coated panels and articles made from them in terms of aesthetics and design. The coating process itself is often referred to as glazing, enamel coating, decoration, or printing. A variety of technically defined methods and equipment exist for coating. In addition to dry coating, such as by electrostatic powder coating, many coating methods exist in which liquid or paste-like coating materials are applied. This paste can be applied to the surface of the panel by various methods, such as by screen printing, pad printing, transfer printing, or by dipping and spraying. This paste typically consists of ground glass powder, optionally added pigments and / or additives, and organic additives, which are removed during the baking, flow, and leveling of the coating. A variety of known glaze compositions exist for coating glass, glass-ceramic, or ceramic plates.

[0003] For example, DE 197 21 737 C1 describes a lead-free and cadmium-free glass composition for glazing, applying enamel, and decorating glass or glass ceramics, as well as a method for preparing glass ceramics coated with said composition.

[0004] However, in the aforementioned prior art, the inorganic coating applied to the glass substrate is easily peeled off under high temperature or high humidity conditions. Furthermore, the inorganic coating in the prior art cannot provide a color-changing effect. Utility Model Content

[0005] The purpose of this invention is to provide a glass panel with a non-physically separable color-changing layer that is wear-resistant and does not lose its intended effect in high-temperature or high-humidity applications.

[0013] According to a preferred embodiment of the present invention, the texture layer is arranged on the glass substrate at least partially in a regular or irregular structure or pattern.

[0014] According to a preferred embodiment of the present invention, the background layer is a coating, spraying layer, printing layer or film disposed on the color-changing layer.

[0022] Figure 1 The structure of a glass panel according to a specific embodiment of the present invention is shown. In this embodiment, the glass panel includes a glass substrate 10 having a front side 101 facing the observer and a back side 102 opposite thereto. The glass panel 10 defines a thickness t between the front side 101 and the back side 102, the thickness t ranging from 2 to 10 mm, preferably from 3 to 8 mm, and more preferably 3.2, 4, 5, 6, or 8 mm.

[0023] The glass panel also includes a color-changing layer 11 formed on the back side 102 of the glass substrate 10 and a background layer 12 formed on the color-changing layer 11. The color-changing layer 11 provides the color-changing effect for the glass panel, while the background layer 12 provides the background color for the glass panel. This background color, combined with the color-changing layer 11, allows the glass panel to display different color effects. For example, if the background color is white, the glass panel can display a purple effect when viewed from the front.

[0024] Figure 3 It shows the manufacturing process. Figure 1 The manufacturing process of the glass panel is shown in the figure.

[0025] The process includes steps S11-S14. In step S11, inorganic ink is printed on the back side 102 of the glass substrate 10 using high-temperature inorganic ink to form a color-changing layer 11.

[0026] In step S12, the glass substrate 10 with the color-changing layer 11 printed on it is subjected to high-temperature heat treatment so that the printed inorganic ink can penetrate into the glass substrate 10.

[0027] In step S13, a background layer 12 is coated on the surface of the color-changing layer 11 opposite to the glass substrate 10. The background layer 12 is mainly formed by ink or coating containing pigments to provide a background color for the glass panel.

[0028] Finally, in step S14, the glass substrate 10 is subjected to high-temperature heat treatment to sinter the background layer 12 onto the color-changing layer 11. The resulting glass panel cannot be physically separated from the color-changing layer 11, the color-changing layer 12, and the glass.

[0029] Figure 2 The structure of a glass panel according to another specific embodiment of the present invention is schematically shown. In this embodiment, the glass panel includes a glass substrate 20 having a front side 201 facing the observer and a back side 202 opposite thereto. The glass panel 20 defines a thickness t between the front side 201 and the back side 202, the thickness t ranging from 2 to 10 mm, preferably from 3 to 8 mm, and more preferably 3.2, 4, 5, 6, or 8 mm.

[0030] The glass panel also includes a color-changing layer 21 formed on the back surface 202 of the glass substrate 20 and a background layer 22 formed on the color-changing layer 21. The color-changing layer 21 provides the color-changing effect for the glass panel, while the background layer 22 provides the background color for the glass panel. This background color, combined with the color-changing layer 21, allows the glass panel to display different color effects. For example, if the background color is blue, the glass panel can appear purple when viewed from the front.

[0031] The glass panel also includes a textured layer 23 formed on the front side 201 of the glass substrate 20. The textured layer 23 provides a textured structure 230 for the glass panel, which is generally applied to the glass substrate 20 at least partially, preferably entirely, in a regular or irregular structure or pattern.

[0032] Figure 4 It shows the manufacturing process. Figure 2 The glass panel manufacturing process is shown in the diagram. This process includes steps S21-S26.

[0033] In step S21, the high-temperature inorganic ink described above is used to print on the back side 202 of the glass substrate 20 to form a color-changing layer 21.

[0034] In step S22, a background layer 22 is coated on the surface of the color-changing layer 21 opposite to the glass substrate 20. The background layer 22 is mainly formed by ink or coating containing pigment to provide a background color for the glass panel.

[0035] In step S23, the glass substrate 20 is subjected to high-temperature heat treatment to sinter the background layer 22 onto the color-changing layer 21. The resulting glass panel contains a color-changing layer 21, a background layer 22, and a glass substrate that cannot be physically separated.

[0036] In step S24, a texture layer 23 is printed on the front side 201 of the glass substrate 20, and in step S25, a heat treatment is performed to sinter the texture layer 23 onto the glass substrate 20.

[0037] In this embodiment, used for Figure 1 Color-changing layer 11 or Figure 2 The inorganic ink of the color-changing layer 21 includes the following oxides as components, in wt%:

[0038] Components wt% <![CDATA[F2O]]> 0.5~2.5 <![CDATA[Na2O]]> 16~24 <![CDATA[Al2O3]]> 1~5 <![CDATA[SiO2]]> 35~45 <![CDATA[K2O]]> 0.5~2.5 <![CDATA[TiO2]]> 3~9 ZnO 11~19 Colored metallic powder 2~10 organic solvents 10~19

[0039] According to this invention, since the color-changing layer cannot be physically separated from the glass substrate, the glass panel has excellent durability in high-temperature or high-humidity application environments, and can therefore be used as a display panel in high-temperature and high-humidity environments such as stoves.
