[0017] See also Figure 1 , which is a schematic structural diagram of the heat-insulating glass structure in an embodiment of the present invention.

[0018] The insulating glass structure of the embodiment of the present invention includes an anti-scratch protective layer, a glass body layer, an ultraviolet blocking layer, a metal layer and a peeling layer; the anti-scratch protective layer is arranged on the first surface of the glass body layer, and the thickness of the anti-scratch protective layer is 0.15-0.20mm; the ultraviolet blocking layer is arranged on the second surface of the glass body layer, and the thickness of the ultraviolet blocking layer is 0.25-0.35mm; the metal layer is arranged on the side of the ultraviolet blocking layer away from the glass body layer, and the thickness of the metal layer is 0.08-0.12mm; the peeling layer is arranged on the side of the metal layer away from the ultraviolet blocking layer.

[0019] In the embodiment of the present invention, the performance of the glass is greatly improved by arranging film layers with various properties on the glass body layer and setting the film layers within a certain thickness range.

[0020] Specifically, the thickness of the anti-scratch protective layer is 0.15-0.20 mm, for example, it can be 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.20 mm, etc. Of course, the thickness of the anti-scratch protective layer can also be set to other values ​​within the range of 0.15-0.20 mm according to actual use requirements, which will not be described in detail here. In this embodiment, the anti-scratch protective layer is provided on the first surface of the glass body layer, and its thickness is set to 0.15-0.20 mm, so as to ensure the normal light transmission of the glass and avoid affecting the line of sight while ensuring the role of preventing scratches by foreign objects.

[0021] In an optional embodiment, the anti-scratch protective layer includes polyurethane. In a specific implementation, butyl acetate can be used to prepare a polyurethane coating liquid, and ultraviolet irradiation can be used during curing.

[0022] Specifically, the thickness of the ultraviolet blocking layer is 0.25-0.35 mm, for example, it can be 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.30 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, etc. Of course, the thickness of the ultraviolet blocking layer can also be set to other values ​​within the range of 0.25-0.35 mm according to actual use requirements, and no further details are given here. In this embodiment, the ultraviolet blocking layer is arranged on the second surface of the glass body layer, and its thickness is set to 0.25-0.35 mm, so as to ensure the normal light transmission of the glass and avoid affecting the line of sight while ensuring the role of blocking ultraviolet rays from passing through the glass.

[0023] In an optional embodiment, the ultraviolet blocking layer is composed of a hardened coating, an ultraviolet absorber and an ultraviolet reflector. Exemplarily, the ultraviolet absorber is mainly an epoxy resin, and the ultraviolet reflector is mainly a coating containing a metal or a metal oxide. The coating can be selected from dibutyl ether and propylene glycol methyl ether as solvents, and the metal component as the solute can be, for example, aluminum or zinc, and the metal oxide component can be, for example, zinc oxide or titanium oxide. In a specific implementation, the hardened coating, the ultraviolet absorber and the ultraviolet reflector are mixed and then coated on the anti-scratch protective layer and allowed to cure.

[0024] Specifically, the thickness of the metal layer is 0.08-0.12 mm, for example, it can be 0.08 mm, 0.09 mm, 0.10 mm, 0.11 mm, 0.12 mm, etc. Of course, the thickness of the metal layer can also be set to other values ​​within the range of 0.08-0.12 mm according to actual use requirements, which will not be described in detail here. In this embodiment, the metal layer is arranged on the side of the ultraviolet blocking layer away from the glass body layer, and its thickness is set to 0.08-0.12 mm, so as to ensure the normal light transmission of the glass and avoid affecting the line of sight while ensuring that it can reflect strong light to achieve heat insulation.

[0025] In an optional embodiment, the metal layer is made of one or more of aluminum, copper, chromium, titanium and nickel. In a specific implementation, for example, ion sputtering can be used to form the metal layer on the ultraviolet blocking layer using the above materials as targets.

[0026] In an optional embodiment, the peeling layer is a PET film, the main component of which is polyethylene terephthalate. The peeling layer is arranged on the side of the metal layer away from the ultraviolet blocking layer, and plays a role in protecting the metal layer during the production or transportation process. In actual use, the peeling layer is removed. Exemplarily, the thickness of the peeling layer is 0.15-0.25mm, for example, it can be 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.20mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm, 0.25mm, etc. Of course, the thickness of the metal layer can also be set to other values ​​according to actual use requirements, which will not be further elaborated here.

[0027] In an optional embodiment, the metal layer is provided with a plurality of first through grooves, the ultraviolet blocking layer is provided with a plurality of second through grooves, and the plurality of first through grooves are connected to the plurality of second through grooves in a one-to-one correspondence to form a plurality of third through grooves.

[0028] In an embodiment of the present invention, the metal layer is provided with a plurality of first through-grooves, and the ultraviolet blocking layer is provided with a plurality of second through-grooves, and the plurality of first through-grooves are connected with the plurality of second through-grooves in a one-to-one correspondence to form a plurality of third through-grooves, that is, one first through-groove is connected with one second through-groove to form a third through-groove. This embodiment provides the metal layer with a plurality of first through-grooves, and the ultraviolet blocking layer is provided with a plurality of second through-grooves, and the plurality of first through-grooves are connected with the plurality of second through-grooves in a one-to-one correspondence to form a plurality of third through-grooves, which has at least the following effects: first, in practical applications, the metal layer and the ultraviolet blocking layer contain materials that affect the passage of signals, and by providing the third through-grooves, the signals can pass smoothly, thereby improving the signal passing capacity; second, when the metal layer and the ultraviolet blocking layer are heated due to sunlight or other reasons, the third through-grooves can be used as a reserved expansion space to avoid damage, thereby ensuring that the metal layer and the ultraviolet blocking layer are stably arranged on the insulating glass.

[0029] In a specific implementation, the third through groove is formed, for example, by laser or other methods.

[0030] Specifically, the width of the third through groove is 45-95 microns, for example, it can be 45 microns, 50 microns, 55 microns, 60 microns, 65 microns, 70 microns, 75 microns, 80 microns, 85 microns, 90 microns, 95 microns, etc. Of course, the width of the third through groove can also be set to other values ​​according to actual use requirements, which will not be described in detail here. In this embodiment, the width of the third through groove is 45-95 microns to facilitate the smooth passage of the signal while avoiding a significant impact on the appearance of the insulating glass.

[0031] Specifically, the distance between each two adjacent third through grooves is 5-9mm, for example, it can be 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, etc., to ensure smooth passage of the signal while avoiding a significant impact on the appearance of the insulating glass. Of course, the distance between each two adjacent third through grooves can also be set to other values ​​according to actual use requirements, which will not be elaborated here.

[0032] In an optional embodiment, a portion of the plurality of third through grooves are provided with adhesive, and a portion of the plurality of third through grooves are not provided with adhesive; the third through grooves provided with adhesive and the third through grooves not provided with adhesive are arranged in sequence at intervals.

[0033] Exemplarily, the adhesive may be, for example, epoxy resin, phenolic resin, etc. In this embodiment, by providing adhesive in some of the plurality of third through grooves, and not providing adhesive in some of the plurality of third through grooves, the third through grooves provided with adhesive and the third through grooves not provided with adhesive are sequentially spaced apart, so as to provide buffering capacity by means of adhesive, so that the metal layer and the ultraviolet blocking layer have a certain expansion space when heated. In addition, the adhesive will not cause excessive obstruction to the signal, and the signal passing ability without adhesive is better. Therefore, by sequentially spaced apart the third through grooves provided with adhesive and the third through grooves not provided with adhesive, a good signal passing effect is obtained and the metal layer and the ultraviolet blocking layer are ensured to be stably provided on the insulating glass. In addition, the adhesive may be provided in a color similar to the insulating glass, and of course, other colors may be selected as needed.

[0034] In another optional implementation, adhesive may be provided in each of the third through grooves or not according to actual requirements.

[0035] In an optional embodiment, a plurality of openings are formed on the adhesive in the third through groove to facilitate signal passage. In addition, due to sunlight exposure and other reasons, the plurality of openings can reserve a larger expansion space for the metal layer and the UV blocking layer, and facilitate heat dissipation of the insulating glass through the openings.

These improvements and substitutions should also be regarded as the scope of protection of the present invention.
