Description

Technical Field

[0001] This utility model relates to the field of glass coating technology, specifically a coated glass panel. Background Technology

[0002] With the rapid development of the construction and decoration industry, glass panels are widely used in curtain walls, doors and windows, displays, and other fields due to their light transmission and aesthetics. However, traditional glass panels have the following problems during use: First, the surface is easily contaminated with dust, oil, and other pollutants, resulting in high cleaning and maintenance costs; second, they are prone to glare in strong light environments, affecting visual comfort; and third, their surface hardness is insufficient, making them easily scratched and affecting their service life. While some coated glass on the market currently possesses certain self-cleaning or anti-glare functions, these functions are often limited and cannot simultaneously meet multiple needs. Furthermore, the existing coated glass film structure design is not optimized enough, leading to problems such as poor self-cleaning effect, unstable anti-glare performance, or poor durability.

[0003] Therefore, there is a need to develop and provide a coated glass panel that combines efficient self-cleaning, excellent anti-glare, and high durability. Utility Model Content

[0004] The purpose of this invention is to provide a coated glass panel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Preferably, the thickness of the first hydrophobic film layer is 20±2nm, the thickness of the second photocatalytic film layer is 50±3nm, the thickness of the third hydrophilic film layer is 30±2nm, the thickness of the fourth antireflective film layer is 80±5nm, the thickness of the fifth scattering film layer is 40±3nm, and the thickness of the sixth hardening film layer is 100±5nm.

[0008] Preferably, the glass substrate is ultra-clear glass with a thickness of 3~10mm, the self-cleaning coating layer has a water contact angle of ≤10°, and the anti-glare composite film layer has a haze value of 10%~30%.

[0009] Preferably, the fifth scattering film layer has a porous structure with a pore size of 100~500nm and a porosity of 20%~40%.

[0011] Preferably, the surface hardness of the sixth hardened film layer is ≥9H, and the number of abrasion cycles under a load of 500g is ≥5000.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by incorporating a self-cleaning coating layer and an anti-glare composite film layer, enables the glass panel to simultaneously possess efficient self-cleaning and anti-glare functions, meeting diverse usage needs. The self-cleaning coating layer adopts a multi-layer structure design of hydrophobic-photocatalytic-hydrophilic. The hydrophobic film layer prevents pollutant adhesion, the photocatalytic film layer decomposes organic pollutants under ultraviolet light, and the hydrophilic film layer promotes water film formation and removes pollutants. The synergistic effect of these three layers significantly improves self-cleaning efficiency. The anti-glare composite film layer, through the combination of anti-reflection, scattering, and hardening film layers, effectively reduces visible light reflectivity, reduces glare, and simultaneously enhances surface hardness and wear resistance, extending service life.

[0014] 2. The materials and thicknesses of each film layer in this invention have been optimized to ensure a balance between functionality and durability. For example, the combination of a hydrophobic fluoride film layer and a hardened silicon carbide film layer guarantees performance while improving environmental adaptability. Furthermore, the glass panel has a simple structure, is easy to mass-produce, and can be widely used in construction, home furnishings, electronic equipment, and other fields.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 As shown, this utility model provides a coated glass panel, which achieves a dual function of self-cleaning and anti-glare by coating the surface of the glass panel. Specifically, the coated glass panel includes a glass substrate 1, a self-cleaning coating layer 2, and an anti-glare composite film layer 3. Specifically, the glass substrate 1 has a front and a back side facing away from each other, the self-cleaning coating layer 2 is disposed on the front side, and the anti-glare composite film layer 3 is disposed on the back side. Further optimized, the glass substrate 1 is an ultra-clear glass with a thickness of 3~10mm, whose high light transmittance and low impurity characteristics provide a good foundation for the coating function.

[0019] More specifically, the self-cleaning coating layer 2 includes a first hydrophobic film layer 21, a second photocatalytic film layer 22, and a third hydrophilic film layer 23 arranged sequentially from the front outwards. Preferably, the first hydrophobic film layer 21 is made of silicon fluoride and has a thickness of 20±2 nm. Its low surface energy properties effectively prevent water stains and contaminant adhesion. The second photocatalytic film layer 22 is made of titanium dioxide and has a thickness of 50±3 nm. Under ultraviolet light irradiation, it can degrade organic pollutants with a degradation efficiency of ≥90%. The third hydrophilic film layer 23 is made of silicon dioxide and has a thickness of 30±2 nm. Its hydrophilic properties allow water to form a uniform water film on the surface, carrying away the decomposed contaminants. The synergistic effect of the three layers ensures that the contact angle of the self-cleaning coating layer 2 with water is ≤10°, significantly improving the self-cleaning effect.

[0020] More specifically, the anti-glare composite film layer 3 includes a fourth anti-reflective film layer 31, a fifth scattering film layer 32, and a sixth hardening film layer 33 arranged sequentially from the back side outwards. Furthermore, the fourth anti-reflective film layer 31 is made of silicon nitride with a thickness of 80±5nm, effectively reducing visible light reflectivity to ≤5%. The fifth scattering film layer 32 is made of aluminum oxide with a thickness of 40±3nm; its porous structure (pore size 100~500nm, porosity 20%~40%) scatters strong light, controlling the haze value to 10%~30% and avoiding glare interference. The sixth hardening film layer 33 is made of silicon carbide with a thickness of 100±5nm, a surface hardness ≥9H, and a friction resistance of ≥5000 cycles under a 500g load, significantly improving the wear resistance and durability of the glass panel.

[0021] In practical applications, the fabrication process of this coated glass panel can be further optimized. For example, functional films can be sequentially deposited on the surface of the glass substrate 1 using magnetron sputtering or chemical vapor deposition. Preferably, the thickness and uniformity of each film layer need to be precisely controlled during the deposition process to ensure the stability of the functional performance. Furthermore, the silicon fluoride of the first hydrophobic film layer 21 can be formed by plasma-enhanced chemical vapor deposition (PECVD), the titanium dioxide of the second photocatalytic film layer 22 can be prepared by reactive sputtering, and the silicon dioxide of the third hydrophilic film layer 23 can be formed by sol-gel method or sputtering. The anti-glare composite film layer 3 can also be achieved by similar physical or chemical deposition processes, wherein the porous structure of the fifth scattering film layer 32 can be formed by adjusting the deposition parameters or by subsequent etching processes.

[0022] The coated glass panel of this invention can be widely used in building curtain walls, automotive glass, electronic device screens, and other fields. For example, when used as a building curtain wall, its self-cleaning function can significantly reduce cleaning and maintenance costs, while its anti-glare function improves indoor visual comfort; when used as a cover plate for electronic device screens, its high hardness and wear resistance can effectively extend the product's service life. Furthermore, the thickness of the glass substrate 1 can be adjusted according to actual needs; for example, a thicker substrate (e.g., 8-10mm) can be selected for architectural glass, while a thinner substrate (e.g., 3-5mm) can be selected for electronic device screens.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
