Description

Technical Field

[0001] This utility model relates to a glass panel with a high-temperature resistant mirror effect, which has a mirror layer that cannot be physically separated, is suitable for high-temperature or high-humidity applications, and provides mirror effects in different colors. 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 technical solutions disclosed in the prior art, the mirror layer on the glass substrate will wear down after prolonged use and is easily peeled off in high-temperature or high-humidity applications. Furthermore, this inorganic coating cannot provide different mirror effects. Utility Model Content

[0005] The purpose of this invention is to provide a glass panel with a non-physically separable mirror layer that is wear-resistant in high-temperature or high-humidity applications without losing its intended effect.

[0006] Another objective of this invention is to provide a glass panel that can provide a high-temperature resistant mirror finish.

[0007] Another objective of this invention is to provide a glass panel that can provide different background effects.

[0008] The glass panel according to this utility model includes a glass substrate, comprising a front side facing the observer and a back side opposite thereto; a mirror layer formed on the glass substrate; and a texture layer formed on the mirror layer, having a textured structure or pattern. The mirror layer, the texture layer, and the glass substrate cannot be physically separated.

[0009] According to a preferred embodiment of this invention, the glass panel further includes a background layer. This background layer provides a background color or background color layer for the glass substrate, and is combined with the mirror layer to provide localized text, symbols, and textures of different colors on the glass substrate.

[0010] According to a preferred embodiment of the present invention, the mirror layer is formed on the front side of the glass substrate, while the background layer is formed on the back side of the glass substrate.

[0011] According to a preferred embodiment of the present invention, the mirror layer is formed on the back of the glass panel, while the background layer is formed on the texture layer.

[0012] According to the preferred technical solution of this utility model, the texture layer can be a full-page, partial structure, regular array arrangement structure, or irregular array arrangement structure.

[0013] According to the preferred embodiment of this utility model, the background layer is a coating, a sprayed layer, a printed layer, or a laminate.

[0014] According to a preferred embodiment of the present invention, the mirror layer comprises a gold oxide.

[0015] According to the preferred technical solution of this utility model, a method of using high-temperature ink to form text, symbols, textures, partial or full-page mirror surfaces on glass provides a mirror effect to the glass panel. In this case, different colors of mirror effects exist. When the mirror layer covers the front of the glass, the text, symbols, textures, and partial mirror surfaces have a three-dimensional effect, which is more likely to attract consumer attention and appreciation.

[0022] Figure 1 The structure of a glass panel according to a specific embodiment of the present invention is schematically 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 mirror layer 11 formed on the front side 101 of the glass substrate 10, a texture layer 12 formed on the mirror layer 11, and a background layer 13 formed on the back side 102 of the glass substrate 10. The mirror layer 11 provides a mirror effect to the glass panel and is generally applied to the glass substrate 10 in a regular or irregular manner, at least partially and preferably entirely. The background layer 13 provides a background color to the glass panel, which, combined with the mirror structure of the mirror layer 11, allows the glass panel to exhibit different colored mirror effects. For example, if the background color is black, the glass panel can exhibit a silver effect. The texture layer 12 provides a textured structure or pattern to the glass panel and is generally applied to the mirror layer 11 in a regular or irregular manner, at least partially and preferably entirely.

[0024] Figure 3 It shows the manufacturing process. Figure 1 The process steps for the glass panel shown are as follows. The process includes steps S11-S15. In step S11, a background layer 13 is coated on the back side 102 of the glass substrate 10, and then heat treatment is performed in step S12. The background layer 13 is mainly formed of high-temperature inorganic ink containing pigments to provide a background color for the glass panel. It can be a coating, spraying layer, printing layer, or lamination formed using high-temperature inorganic ink.

[0025] In step S13, high-temperature ink is used for mirror printing. In step S14, texture layer 12 is printed and formed on mirror layer 11. In step S15, heat treatment is performed so that the ink of texture layer 12 can penetrate into mirror layer 11. Under these conditions, mirror layer 11 and texture layer 12 cannot be physically separated.

[0026] Figure 4 It shows the manufacturing process. Figure 1 Another process step for the glass panel shown is as follows. This process includes steps S21-S25. In step S21, a mirror layer 11 is printed on the front side 101 of the glass substrate 10. Then, in step S22, a texture layer is printed and formed on the mirror layer 11, followed by a heat treatment in step S23. In step S24, a background layer is coated to provide a background color for the glass panel. This can be a coating, sprayed layer, printed layer, or laminate formed using high-temperature inorganic inks.

[0028] The glass panel also includes a mirror layer 21 formed on the front side 201 of the glass substrate 20 and a background layer 22 formed on the back side 202 of the glass substrate 20. The mirror layer 21 provides a mirror effect to the glass panel and is generally applied to the glass substrate 20 in a regular or irregular manner, at least partially and preferably entirely. The background layer 22 provides a background color to the glass panel, which, combined with the mirror structure of the mirror layer 21, allows the glass panel to exhibit different colored mirror effects. For example, if the background color is black, the glass panel can exhibit a silver effect. The mirror layer 21 provides a textured structure or pattern to the glass panel and is generally applied to the glass substrate 20 in a regular or irregular manner, at least partially and preferably entirely.

[0029] Figure 5 It shows the manufacturing process. Figure 2 The process steps for the glass panel shown are as follows. The process includes steps S31-S34. In step S31, a background layer is coated on the back side 202 of the glass substrate 20, followed by heat treatment in step S32. In step S33, a mirror layer 21 is formed by high-temperature ink printing on the front side 201 of the glass substrate 20, followed by heat treatment in step S34.

[0030] Figure 6 It shows the manufacturing process. Figure 2 Another process step for the glass panel shown is as follows. This process includes steps S41-S44. In step S41, a mirror finish is printed on the front side 201 of the glass substrate 20 using high-temperature ink, and in step S42, a heat treatment is performed to form a mirror layer 21. In step S43, a background layer is coated on the back side 202 of the glass substrate 20, and then a heat treatment is performed in step S34. In this case, the mirror layer 21 and the glass 20 cannot be physically separated.
