Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass manufacturing technology, specifically to a temperable coated glass with gradually varying transmittance and reflectance. Background Technology
[0002] Gradient glass is a decorative glass product where the color and transmittance gradually change on the same piece of glass. It is widely used in high-end decoration and building curtain walls. Currently, the most common approximation is to use gradient film to create laminated glass from two pieces of glass, or to use a color gradient film. However, this is not a characteristic inherent to the glass itself, and this method has the following drawbacks: laminated glass requires two pieces of glass and film, resulting in high material costs; gradient film for laminated glass is expensive and requires additional processing; films or films are prone to aging, discoloration, and delamination, leading to decreased optical performance and poor weather resistance over long-term use; production is inconvenient and cannot be carried out on a large scale; the gradient effect of films or films is fixed, making it impossible to adjust transmittance and reflectivity according to needs. Therefore, the market lacks a temperable, weather-resistant, and optically adjustable gradient coated glass. Utility Model Content
[0003] The purpose of this invention is to overcome or at least partially solve the above-mentioned problems by proposing a temperable coated glass with gradually varying transmittance and reflectance.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a temperable coated glass with gradually varying transmittance and reflectance, comprising:
[0005] Glass substrate;
[0006] A gradient coating layer is disposed on the surface of a glass substrate. The gradient effect of the gradient coating layer is controlled by a magnetron sputtering baffle to block part or all of the sputtered material. The gradient coating layer includes an isolation layer, an absorption and reflection layer and a protective layer disposed sequentially from the surface of the glass substrate outward.
[0007] In a preferred embodiment, the material of the insulating layer is selected , , One or more combinations thereof, wherein the material of the absorbing and reflecting layer is selected from , , One or more combinations thereof, wherein the material of the protective layer is selected from , , , One or more combinations thereof.
[0008] In a preferred embodiment, the thickness of both the isolation layer and the absorption and reflection layer is 10nm~60nm, and the thickness of the protective layer is 30nm~60nm.
[0009] In a preferred embodiment, the magnetron sputtering baffle has an irregular shape, and the area exhibiting a gradient effect is the irregular shape portion of the magnetron sputtering baffle.
[0010] In a preferred embodiment, the gradient coating layer forms a continuous gradient structure on the surface of the glass substrate 1, including a low light transmittance region, a gradient region, and a high light transmittance region.
[0011] In a preferred embodiment, the gradient coating layer in the high-transmittance area comprises only an isolation layer and a protective layer, and the absorption and reflection layer is absent in this area.
[0012] In a preferred embodiment, the gradient coating layer in the high-transmittance area is completely absent, directly exposing the surface of the glass substrate.
[0013] In a preferred embodiment, the gradient coating layer in the low-transmittance region includes an isolation layer, an absorption and reflection layer, and a protective layer.
[0014] In a preferred embodiment, the irregular structure includes, but is not limited to, a sawtooth shape, a stepped shape, or a wedge shape.
[0015] Compared with existing technologies, this utility model provides a temperable coated glass with gradient transmittance and reflectance. It only requires a single glass substrate and three functional film layers to achieve the gradient effect, which significantly reduces the amount of material used compared with traditional laminated glass. The inorganic material coating layer has excellent weather resistance and durability, and will not have the problems of aging, discoloration, and delamination that occur with traditional film products. At the same time, the synergistic effect of the three functional film layers and the magnetron sputtering baffle ensures precise gradient of film thickness and achieves wide-range transmittance adjustment. The magnetron sputtering baffle can adjust the position, range, and rate of change of the gradient area according to actual needs to achieve multiple gradient modes and meet the personalized needs of different application scenarios.

[0022] This invention relates to a temperable coated glass with gradually varying transmittance and reflectance, which solves the technical problems in the prior art. The overall concept is as follows:
[0023] Example 1:
[0024] Please see Figures 1-3 A temperable coated glass with gradient transmittance and reflectance includes: a glass substrate 1 and a gradient coating layer disposed on the surface of the glass substrate 1. The gradient effect of the coating layer is controlled by a magnetron sputtering baffle to block part or all of the sputtered material. The gradient coating layer includes an isolation layer 2, an absorption and reflection layer 3, and a protective layer 4 disposed sequentially from the surface of the glass substrate 1 outwards. The material of the isolation layer 2 is selected from... , , One or more combinations thereof, the material of the absorbing and reflecting layer 3 is selected , , One or more combinations thereof, the material of protective layer 4 is selected , , , One or more combinations thereof.
[0025] In practice, the thickness of the isolation layer 2 and the absorption and reflection layer 3 is 10nm~60nm, and the thickness of the protective layer 4 is 30nm~60nm.
[0026] In practice, the magnetron sputtering baffle has an irregular structure, and the area that presents a gradient effect is the irregular structure part of the magnetron sputtering baffle. The irregular structure includes, but is not limited to, a sawtooth shape, a stepped shape, or a wedge shape.
[0027] In specific implementation, the gradient coating layer forms a continuous gradient structure on the surface of the glass substrate 1, including a low light transmittance area, a gradient area, and a high light transmittance area. Option 1: The gradient coating layer in the high light transmittance area only includes the isolation layer 2 and the protective layer 4, and the absorption and reflection layer 3 is missing in this area. The gradient coating layer in the low light transmittance area includes the isolation layer 2, the absorption and reflection layer 3, and the protective layer 4. Option 2: The gradient coating layer in the high light transmittance area is completely missing, directly exposing the surface of the glass substrate 1. The gradient coating layer in the low light transmittance area includes the isolation layer 2, the absorption and reflection layer 3, and the protective layer 4.
[0028] This embodiment precisely controls film deposition using a magnetron sputtering baffle with an irregular structure, achieving a continuous / stepped optical gradient on the glass surface. Two options are provided: Option 1's high-transmittance area contains only the isolation layer 2 and the protective layer 4, balancing high transmittance with surface protection; Option 2's high-transmittance area has no coating, maximizing light-gathering efficiency. Both options meet the core requirements of temperability, high durability, and smooth gradient. The specific choice can be determined based on light transmittance requirements and environmental adaptability. The low-transmittance portion of this embodiment has excellent sunshade and ultraviolet reflection effects, and can also be applied to products such as integrated sunroofs and windshields for automobiles and yachts.

It is obvious to those skilled in the art that various modifications can be made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments. Any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
