Description

Technical Field

[0001] This utility model relates to glass, and more particularly to a scratch-resistant and wear-resistant glass. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material used for wind insulation and light transmission, and is widely used in construction, daily necessities, art, medical, chemical, electronic, instrumentation and nuclear engineering fields.

[0003] Tempered glass is a type of prestressed glass. To improve its strength, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external forces, this surface stress is first neutralized, thereby increasing its load-bearing capacity. Tempered glass has become increasingly widely used in daily life in recent years, particularly in doors, windows, and various types of insulation. However, existing tempered glass often features a simple wear-resistant layer structure, resulting in weak adhesion between the wear-resistant layer and the glass itself. If peeling occurs in one area of ​​the wear-resistant layer, it can easily lead to the entire layer separating, posing a significant safety hazard. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1:

[0023] Figure 1-5 The illustrated scratch-resistant and wear-resistant glass includes a base glass layer 1, a hollow layer disposed inside the base glass layer 1, a sealant 8 bonded to the outer ring inside the hollow layer, a silica aerogel 7 filled inside the hollow layer, a desiccant 9 filled between the silica aerogel 7 and the sealant 8, and a breathable barrier layer disposed between the desiccant 9 and the silica aerogel 7. In this embodiment, the sealant 8 is silicone adhesive, and the breathable barrier layer is a microporous membrane to prevent physical contact while ensuring water vapor adsorption efficiency.

[0024] The left and right sides of the base glass layer 1 are provided with a plurality of first grooves 3 at equal intervals, and a first protrusion 2 is formed between two first grooves 3; the thickness of the base glass layer 1 is 10-22mm; in this embodiment, the thickness of the base glass layer 1 is 20mm.

[0025] A PVB adhesive layer and a composite wear-resistant layer 4 are sequentially disposed on the outer surface of the base glass layer 1 from the inside out. The composite wear-resistant layer is bonded to the outer surface of the base glass layer 1 by coating the PVB adhesive layer. Several second grooves 6 are evenly spaced on the inner sidewall of the composite wear-resistant layer 4, and a second protrusion 5 is formed between two second grooves 6. The first groove 3 on the base glass layer 1 is press-fitted with the second protrusion 5 of the composite wear-resistant layer 4, and the second groove 6 on the base glass layer 1 is press-fitted with the first protrusion 2 of the composite wear-resistant layer 4. In this embodiment, the two side walls of the first groove 3 are parallel to each other, the two side walls of the second groove 6 are parallel to each other, and both the first protrusion 2 and the second protrusion 5 are square structures.

[0026] In this embodiment, the composite wear-resistant layer 4 is provided with a nano zinc dioxide coating 41, a nano titanium dioxide coating 42 and a nano silicon dioxide coating 43 from the inside to the outside.

[0027] The nano zinc dioxide coating 41 has a thickness of 18-30 nm, providing basic mechanical support and composite functions. Its antibacterial properties can inhibit the growth of microorganisms on the surface of the base glass layer 1, and it also has an ultraviolet shielding function, which can reduce the aging of the base glass layer 1 due to ultraviolet radiation. The nano titanium dioxide coating 42 has a thickness of 10-15 nm and strong chemical stability. It is resistant to acid and alkali corrosion and can protect the inner nano zinc dioxide coating 41 from environmental erosion, extending the overall lifespan of the composite wear-resistant layer 4. The nano silica coating 43 has a thickness of 9-15 nm. The high hardness and wear resistance of silica can directly resist external friction. In this embodiment, a second groove 6 and a second protrusion 5 are formed on the nano zinc dioxide coating 41.

[0028] In this embodiment, the thickness of the nano zinc dioxide coating 41 is set to 18 nm, the thickness of the nano titanium dioxide coating 42 is set to 12 nm, and the thickness of the nano silicon dioxide coating 43 is set to 10 nm. The nano zinc dioxide coating, the nano titanium dioxide coating 42, and the nano silicon dioxide coating 43 are connected by magnetron sputtering. This configuration results in high coating density and strong process controllability.

[0029] A first groove 3 is formed on the base glass layer 1, which is interference-fitted and bonded to the second protrusion 5 on the composite wear-resistant layer 4 through a PVB adhesive layer. A second groove 6 is formed on the base glass layer 1, which is interference-fitted and bonded to the first protrusion 2 on the composite wear-resistant layer 4 through a PVB adhesive layer. This upgrades the traditional single planar bonding mode to a composite connection method with three-dimensional interlocking and chemical bonding synergy. It can achieve a dual combination of interlocking and chemical bonding force, significantly reducing the risk of peeling due to single adhesive failure, and effectively improving the safety and service life of the structure.

[0030] Example 2:

[0031] In this embodiment, the first groove 3, the second groove 6, the first protrusion 2, and the second protrusion 5 are all semi-circular structures. It should be noted that all four have the same radius; in this embodiment, the radius of all four is 10 nm. This allows the composite wear-resistant layer 4 to align quickly and precisely, significantly reducing the debugging time and operational difficulty during installation, greatly improving installation efficiency, and making the installation of the composite wear-resistant layer 4 more convenient and smooth. Furthermore, the trapezoidal structure itself has good mechanical support properties, allowing the entire structure to remain more stable in complex usage environments.

[0032] Example 3: A reinforcing mechanism is also provided in the base glass layer 1. The reinforcing mechanism includes transverse steel wires and longitudinal steel wires, which are arranged in a 1:1 ratio.

[0033] The diameter of the transverse steel wire is 5mm-6mm, and the diameter of the longitudinal steel wire is 5mm-6mm; in this embodiment, the diameter of the transverse steel wire is 5mm, and the diameter of the longitudinal steel wire is 5mm; the spacing between each transverse steel wire and the spacing between each longitudinal steel wire are 30mm, forming a 30mm×30mm square grid to provide balanced support; the longitudinal steel wire is laid first, and then the transverse steel wire is laid. The intersections of the transverse and longitudinal steel wires are fixed by resistance welding to form a rigid mesh; it should be noted that the rigid mesh is preheated, and the rigid mesh is evenly laid on the surface of the molten glass. The rigid mesh is then slowly pressed into the molten glass using a rolling roller to a depth of 1 / 2 the thickness of the glass; then, grooves are set on the surface of the molten glass using a mold; finally, the molten glass is cooled.

[0034] In summary, Embodiments 2 and 3 in this specification mainly describe the differences from Embodiment 1. The same or similar parts between Embodiment 1 and other embodiments can be referred to each other.

[0035] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
