Description

Technical Field

[0001] The utility model relates to the technical field of coated glass, in particular to a high-transmittance coated glass. Background Art

[0002] Coated glass is a product with one or more layers of thin films of metal, alloy, or metal compound applied to the surface of the glass. This coating modifies the optical properties of the glass to meet specific requirements. There are various types of coated glass, including heat-reflective glass, low-emissivity glass (Low-E glass), and conductive glass. Each of these different types of coated glass has unique characteristics and applications.

[0003] Existing coated glass has several drawbacks when it comes to light transmittance. First, its visible light transmittance is low, which means that when the glass area is large, it may have a certain impact on indoor lighting. This problem is particularly pronounced when using darker coated glass. Second, certain types of coated glass (such as heat-reflective glass) can cause glare at certain angles, affecting vision and visual comfort.

[0004] To overcome these shortcomings, manufacturers and researchers have been working to improve the light transmission properties of coated glass. For example, by optimizing the composition and structure of thin film materials and refining the deposition process, the light transmittance of coated glass can be increased to a certain extent. Furthermore, the development of new high-transmittance materials and transparent conductive materials is also an important direction for the future development of coated glass. Utility Model Content

[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] The glass substrate 1 is made of ultra-white glass with high light transmittance.

[0014] The conductive transparent thin film layer 2 is made of indium tin oxide, and has a thickness of 50-200 nm.

[0015] The thickness of the tungsten oxide layer 3 is 20-50 nm.

[0016] The thickness of the titanium dioxide layer 4 is 30-80 nm.

[0017] The thickness of the silicon carbide layer 5 is 50-150 nm.

[0018] The thickness of the diamond film layer 6 is 10-50 nm.

[0019] The thickness of the silicon nitride protective layer 7 is 10-30 nm.

[0020] Manufacturing steps:

[0021] 101. Basic glass preparation

[0022] The basic material is still ultra-white glass with high light transmittance.

[0023] 102. First thin film deposition

[0024] Indium tin oxide (ITO) is used as the conductive transparent film layer, which has high transmittance and low resistivity.

[0025] Thickness requirement: 50-200 nanometers.

[0026] 103. Thermal insulation reinforcement layer

[0027] Added material 1: Tungsten oxide (WO3). Tungsten oxide is a good thermal insulation material that can absorb and reflect infrared rays, thereby reducing the transfer of heat energy.

[0028] Thickness requirement: 20-50 nanometers.

[0029] Additive 2: Titanium dioxide (TiO2). TiO2 has a high refractive index and good light scattering properties, which can increase the glass's reflection of sunlight and improve the heat insulation effect.

[0030] Thickness requirement: 30-80 nanometers.

[0031] 104. Wear-resistant reinforcement layer

[0032] Additive material three: Silicon carbide (SiC). Silicon carbide is a super-hard material with excellent wear resistance. It can increase the surface hardness of coated glass and resist scratches and wear.

[0033] Thickness requirement: 50-150 nanometers.

[0034] Added material 4: Diamond film. Diamond is the hardest material in nature, and depositing a diamond film can significantly improve the wear resistance of glass.

[0035] Thickness requirement: 10-50 nanometers (because diamond is expensive, usually only a very thin layer is required).

[0036] 105. Outer protection

[0037] Silicon nitride (Si3N4) is used as the outermost protective layer to increase chemical stability and mechanical strength.

[0038] Thickness requirement: 10-30 nanometers.

[0039] 106. Post-processing

[0040] Coated glass is annealed to eliminate internal stresses and increase stability.

[0041] Hardening treatment is performed to further enhance the mechanical strength of the glass.

[0042] 107.Performance testing and quality inspection

[0043] Use equipment such as spectrum analyzers to test the transmittance, reflectivity and other optical properties of coated glass to ensure that it meets the design requirements.

[0044] Check the mechanical properties and weather resistance of the glass, including hardness, wear resistance, and chemical stability, to ensure product quality.

[0045] 108. Packaging and storage

[0046] Qualified coated glass is packaged to prevent scratches and contamination.

[0047] Store in a dry, dark environment until transport and installation.
