Description

Technical Field

[0001] The utility model belongs to the field of coated glass, and more specifically relates to vacuum coated glass. Background Art

[0002] Vacuum coated glass is a glass product that improves its performance and function by applying vacuum coating technology on the glass surface. Vacuum coated glass has many advantages. It can improve the optical properties of glass and improve the wear resistance and corrosion resistance of glass.

[0003] Existing coated glass generally has a silver coating on the surface of the glass to improve the chemical and physical properties of the glass and to meet the required quality standards. However, the existing silver-coated glass does not have a silver coating protection on the outside, so that the silver coating is easily damaged by external forces, thereby reducing the life of the silver-coated glass and failing to meet the use standards.

[0004] In order to solve the above problems, the prior art adds another protective layer on the outside of the silver-plated layer to improve the protection of the silver-plated layer; however, the design of this coated glass still has the problem of insufficient adhesion of the silver-plated layer, which still shortens the service life of the coated glass. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a vacuum coated glass, which can make the silver layer on the glass have better adhesion, be less prone to oxidation, and extend the service life and performance of the vacuum coated glass.

[0006] The utility model discloses a vacuum coated glass, comprising a base glass, wherein the outer surface of the base glass is coated with a first aluminum oxide layer; the outer surface of the first aluminum oxide layer is coated with a silver layer; and the outer side of the silver layer is covered with a protective layer.

[0007] As a further improvement of the utility model, a second aluminum oxide layer is plated between the silver layer and the protective layer; the second aluminum oxide layer at least completely covers the connection surface between the silver layer and the protective layer; the protective layer is plated on the outer surface of the second aluminum oxide layer. The silver layer has good reflective properties, but silver is easily oxidized and will form an oxide layer when exposed to air, which reduces the service life. Therefore, plating a layer of aluminum oxide as a protective layer can prevent the silver layer from oxidizing and extend its service life.

[0008] As a further improvement of the utility model, the second aluminum oxide layer completely covers the outer side of the silver layer; the protective layer completely covers the outer side of the second aluminum oxide layer. The second aluminum oxide completely covers the silver layer and the protective layer to ensure the contact area between the silver layer and the protective layer, so that the silver layer will not fall off due to too small a contact area.

[0009] As a further improvement of the utility model, the protective layer includes a copper layer; the copper layer completely covers the outer side of the silver layer. Copper has good corrosion resistance and can effectively protect the glass surface from erosion by the external environment, thereby extending the service life of the coated glass.

[0010] As a further improvement of the utility model, the protective layer includes a copper layer; the copper layer completely covers the outer side of the second aluminum oxide layer; the copper layer is plated on the outer surface of the second aluminum oxide layer. The copper layer can improve the reflectivity and transmittance of the coated glass, and has corrosion resistance and can effectively protect the glass surface from erosion by the external environment, thereby extending the service life of the coated glass.

[0011] As a further improvement of the utility model, the protective layer also includes a protective paint layer; the protective paint layer completely covers the outer side of the copper layer. The protective paint layer on the glass is mainly to increase the stability and durability of the coating. The protective paint layer can prevent the silver layer and the copper layer from being corroded by oxides and other chemicals in the air, can reduce scratches and damage on the glass surface, increase the wear resistance of the coating, reduce surface wear caused by friction and contact, and extend the service life of the coating.

[0012] As a further improvement of the present invention, the thickness of the first aluminum oxide layer is 30 nanometers.

[0013] As a further improvement of the present invention, the thickness of the silver layer is 100 nanometers.

[0014] As a further improvement of the present invention, the thickness of the second aluminum oxide layer is 20 nanometers.

[0015] As a further improvement of the present invention, the thickness of the copper layer is 200 nanometers.

[0016] Compared with the prior art, the beneficial effects of the utility model are: due to the strong bonding force of the first aluminum oxide, the silver layer can be better adhered to the glass, thereby increasing the bonding effect of the coating; the silver layer has a high reflectivity, can effectively reflect light, and make the glass surface look brighter, and has a heat-insulating effect to a certain extent; the protective layer plays a protective role in the glass coating process, making the coating more stable and durable.

[0021] Specific embodiment 1: Please refer to Figure 2 A vacuum coated glass is provided, on the surface of a base glass 6, a first aluminum oxide layer 5, a silver layer 4, a second aluminum oxide layer 3, and a copper layer 2 are arranged in sequence from the inside to the outside.

[0022] The first aluminum oxide layer 5 has a thickness of 30 nanometers and is directly plated on the outer surface of the base glass 6 and completely covers the outer surface of the base glass 6, so as to fill the small bumps and unevenness on the glass surface, effectively ensuring that the silver layer 4 is better attached to the outer side of the base glass 6 in the future, making the subsequent silver-plated film more uniform and stable, improving the quality of the coating, and improving the stability and efficiency of the silver-plating process.

[0023] The silver layer 4 is plated on the outer surface of the first aluminum oxide layer 5 and completely covers the first aluminum oxide layer 5. The thickness of the silver layer 4 is 100 nanometers, which makes the glass surface look brighter. The silver layer 4 has a heat-insulating effect to a certain extent; the silver layer 4 can provide a certain degree of privacy protection, making the room difficult to be seen through by the outside world.

[0024] The second aluminum oxide layer 3 has a thickness of 20 nanometers and is plated on the outer surface of the silver layer 4 and completely covers the outer surface of the silver layer 4. The second aluminum oxide layer 3 can form a uniform interface between the silver layer 4 and the copper layer 2, which helps to improve the bonding force between the silver layer 4 and the copper layer 2, enhance the adhesion of the coating, and reduce problems caused by coating peeling.

[0025] The copper layer 2 has a thickness of 200 nanometers; the copper layer 2 is plated on the outer surface of the second aluminum oxide layer 3 and completely covers the second aluminum oxide layer 5. The copper layer 2 can improve the reflectivity and transmittance of the coated glass, and has corrosion resistance, which can effectively protect the glass surface from erosion by the external environment, extend the service life of the coated glass, and make the surface of the coated glass smoother and more uniform, enhancing its appearance.

[0026] Specific embodiment 2: On the basis of specific embodiment 1, a protective paint layer 1 is plated on the outer surface of the copper layer 2 to maintain the surface smoothness and aesthetics, increase the wear resistance of the coating, reduce surface wear caused by friction and contact, increase the gloss and texture of the coating, and make it look more uniform and beautiful.

[0027] Specific embodiment three: The difference from specific embodiment one is that the outer surface of the silver layer 4 is not covered with the second aluminum oxide layer 3, and the copper layer 2 is directly plated on the outer surface of the silver layer 4, thereby reducing cost investment.

[0028] Specific embodiment four: On the basis of specific embodiment three, a protective paint layer 1 is plated on the outer surface of the copper layer 2. The protective paint layer can prevent the silver layer and the copper layer from being corroded by oxides and other chemicals in the air, reduce scratches and damage on the glass surface, increase the wear resistance of the coating, reduce surface wear caused by friction and contact, and extend the service life of the coating.

[0029] The above specific embodiments are also applicable to Figure 3 The case of double-sided plating is shown.
