Description

Technical Field

[0001] The utility model relates to the field of functional glass, in particular to an anti-glare heated glass substrate. Background Art

[0002] Anti-glare glass is a functional material that creates a micron-scale rough structure on the glass surface to scatter incident light, effectively reducing specular reflection and glare interference. It is widely used in electronic displays, in-vehicle central control systems, industrial control, smart homes, and other fields, significantly improving display visibility and user experience, especially in strong light or outdoor environments. Currently, the anti-glare glass structure using existing spraying technology involves sequentially spraying an anti-glare layer and other material layers directly onto the surface of a glass substrate. This structure results in low light transmittance, poor anti-glare properties, and limited adhesion between the anti-glare layer and the glass substrate, and between the anti-glare layer and other material layers. Utility Model Content

[0003] In view of the above technical problems, the purpose of the present invention is to provide an anti-glare heated glass substrate.

[0004] The purpose of the present invention is achieved by the following technical solution: The present invention provides an anti-glare heated glass substrate, comprising a glass substrate having a plurality of through holes and a plurality of grid-like grooves formed on the upper and lower surfaces of the glass substrate; a heating conductive layer is attached to the surface of one of the grooves of the glass substrate, and an anti-fog layer is attached to the surface of the heating conductive layer.

[0005] Furthermore, the distance between two adjacent grooves is 20-50 microns, and the line width of the grooves is 4-10 microns.

[0006] Furthermore, the heating conductive layer is a copper nanowire grid layer.

[0007] Furthermore, the anti-fog layer is a titanium dioxide thin film layer.

[0008] According to the above technical solution, the utility model has the following beneficial effects:

[0009] (1) The glass substrate with the groove structure solves the problem of poor anti-glare performance and low light transmittance when the anti-glare layer and other material layers are laid on the glass substrate in sequence under the existing spraying technology; the heating conductive layer and the anti-fog layer are laid along the surface of the glass substrate and the groove, so that the adhesion between the heating conductive layer and the glass substrate, and between the anti-fog layer and the heating conductive layer is enhanced.

[0010] (2) The through holes provided on the glass substrate of this structure can cooperate with the grooves on the surface of the glass substrate to further improve the anti-glare effect and haze of the glass substrate; when the glass substrate is heated, the through holes can facilitate the heat dissipation of the entire glass substrate.

[0011] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In addition, in order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following specifically cites preferred embodiments and describes them in detail with reference to the accompanying drawings.

[0015] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings, in which preferred embodiments of the present invention are given; however, the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0016] See also Figure 1 The present invention provides an anti-glare heated glass substrate, comprising a glass substrate 1. A plurality of position areas are preset on the upper and lower surfaces of the glass substrate (these areas are the modified areas of the upper and lower surfaces of the cleaned glass substrate at the preset positions after irradiation). Through holes 2 are provided in the aforementioned position areas in a vertical direction. After the through holes are provided, a plurality of grid-like grooves are provided on the upper and lower surfaces of the glass substrate. The spacing between two adjacent grooves 3 is 20-50 microns, and the line width of the grooves 3 is 4-10 microns. In a preferred embodiment of the present invention, the spacing between two adjacent grooves is 30 microns, and the line width is 6 microns. The grooves are provided to change the specular reflection formed when sunlight strikes the glass substrate into diffuse reflection to achieve an anti-glare effect. Compared with a structure in which an anti-glare layer is directly laid on the glass substrate, the structure has stronger light transmittance and better anti-glare effect. The provision of the through holes in combination with the grid-like grooves on the surface of the glass substrate further increases the irregularity of the glass substrate surface, thereby improving the diffuse reflection intensity and haze of the glass substrate surface.

[0017] A heating conductive layer 4 is attached to one of the grooved surfaces of the glass substrate 1. In this embodiment, copper nanowires are sprayed on the aforementioned surface to form a copper nanowire grid conductive layer. This design increases the surface contact area between the heating conductive layer and the glass substrate. In addition, when spraying the copper nanowires, a portion of the copper nanowires will be sprayed into the through-holes on the glass substrate, thereby increasing the adhesion between the copper nanowire grid and the glass substrate and improving wear resistance.

[0018] An anti-fog layer 5 is attached to the surface of the heating conductive layer 4. Its function is, on the one hand, to increase the adhesion between the heating conductive layer and the heating conductive layer, and on the other hand, to slow down the oxidation of the copper nanowire grid and improve the service life. In this embodiment, a titanium dioxide film is deposited on the surface of the copper nanowire grid to maintain the transparency of the glass and prevent water droplets and fog from adhering to the surface.

[0019] Furthermore, the aforementioned heating conductive layer 4 and the anti-fog layer 5 do not cover the through hole 2. By heating the heating conductive layer 4, the evaporation of water vapor and fog on the surface of the glass substrate can be accelerated in a cold environment, thereby avoiding ice formation on the glass surface and maintaining the transparency of the glass substrate. The provided through hole is beneficial to the heat dissipation of the entire glass substrate during the heating process of the glass substrate, thereby avoiding excessive temperature.

[0020] Please also refer to Figure 2 The glass substrate manufacturing method in a preferred embodiment of the present invention is used to manufacture the above-mentioned glass substrate, comprising the following steps:

[0021] Step 1: Cleaning the glass substrate;

[0022] Step 2: Irradiating predetermined locations on the upper and lower surfaces of the cleaned glass substrate to form modified areas;

[0023] Step 3: Etching the modified area to form a through hole;

[0024] Step 4: Soak both sides of the cleaned glass substrate with pure acrylic emulsion and dry it at room temperature. After drying, the pure acrylic emulsion will form cracked grid-like grooves on the surface of the glass substrate;

[0025] Step 5: Place the glass substrate with pure acrylic emulsion on the surface into glass etching solution for etching;

[0026] Step 6: Clean the etching solution on the surface of the glass substrate with deionized water;

[0027] Step 7: Place the cleaned glass substrate in an acetone solution for ultrasonic cleaning to remove the pure acetone crack layer on the surface;

[0028] Step 8: Spraying copper nanowires onto one side of the glass substrate using a spray coating method to form a transparent conductive layer of a conductive copper nanowire grid;

[0029] Step 9: Sputter and deposit a titanium dioxide film on the surface of the copper nanowire grid using magnetron sputtering technology.

[0030] In other embodiments of the present invention, the heating conductive layer may also be made of other materials, such as nano silver wires.

[0031] In other embodiments of the present invention, the anti-fog layer may also be made of other materials, such as silicon dioxide.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the implementation method of the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the design and scope of the technical solution of the utility model.
