Description

Technical Field

[0001] This utility model relates to the field of antibacterial glass technology, and in particular to an antibacterial glass with a self-healing composite coating. Background Technology

[0002] Antibacterial glass is a new type of eco-functional material. Through special deep processing, it possesses bactericidal and bacteriostatic functions. In the medical field, its bactericidal and bacteriostatic functions can effectively prevent the spread of bacteria and viruses, thereby protecting the health of medical staff and patients. Furthermore, antibacterial glass can also be used in the manufacture of medical devices. Since medical devices need to maintain a high degree of hygiene and sterility during use, the use of antibacterial glass can greatly improve the effectiveness and safety of these devices.

[0003] In the actual use of antibacterial glass, the antibacterial coating on the surface is inevitably subjected to various external forces, which can damage it and reduce its antibacterial effect. Therefore, antibacterial glass is often coated with a self-healing composite coating. However, most existing antibacterial glass with self-healing composite coatings lacks a protective glass structure, making it susceptible to breakage due to external forces in the event of an emergency. This results in a reduced lifespan and increased cost of use. Furthermore, the existing antibacterial glass coatings have poor durability and are prone to degradation of antibacterial performance due to scratches and wear. They also lack self-healing capabilities, and the antibacterial performance is irreversibly lost after damage, leading to a reduced lifespan and increased maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an antibacterial glass with a self-healing composite coating, aiming to improve the problem of the lack of glass protective structure in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an antibacterial glass with a self-healing composite coating, comprising a glass substrate, a coating layer fixedly connected to the outer wall of the glass substrate, an outer frame fixedly connected to the outer wall of the coating layer, a plurality of lower connecting columns fixedly connected to the bottom of the inner wall of the outer frame, a plurality of upper connecting columns fixedly connected to the top of the inner wall of the outer frame, a central column slidably connected to the top of the lower connecting columns, a compression spring fixedly connected to the top and bottom of the central column, a plurality of connecting rods rotatably connected to adjacent sides of the upper and lower connecting columns, a rotating shaft rotatably connected to adjacent ends of the connecting rods, a pressure rod fixedly connected to the outer wall of the rotating shaft, a piston fixedly connected to the top of the pressure rod, a gas rod slidably connected to the outer wall of the pressure rod, and a repair mechanism fixedly connected to the inner wall of the outer frame, the repair mechanism being used to help the glass substrate accelerate self-repair.

[0006] As a further description of the above technical solution:

[0007] The repair mechanism includes an ultraviolet regeneration lamp, the outer wall of which is fixedly connected to the front and rear sides of the outer frame, an adhesion layer is fixedly connected to both the front and rear sides of the glass substrate, a self-healing polymer layer is fixedly connected to the opposite side of the adhesion layer, an electrically stimulating conductive wire is provided on the inner wall of the self-healing polymer layer, and an antibacterial active layer is fixedly connected to the opposite side of the self-healing polymer layer.

[0008] As a further description of the above technical solution:

[0009] A controller is fixedly connected to the top left side of the outer frame, and a nameplate is fixedly connected to the top right side of the outer frame.

[0010] As a further description of the above technical solution:

[0011] Multiple positioning plates are fixedly connected to the outer wall of the outer frame, and positioning holes are provided on the top of the positioning plates.

[0012] As a further description of the above technical solution:

[0013] Anti-collision cotton is fixedly connected to the four corners of the outer wall of the outer frame, and a lower protective film is fixedly connected to the bottom of the glass substrate.

[0014] As a further description of the above technical solution:

[0015] The outer walls of both the pressure rod and the air rod are slidably connected to a fixed frame, and the outer wall of the piston is slidably connected to the inner wall of the air rod.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the ultraviolet regeneration lamp is fixedly connected to a protective cover.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, during normal operation, the entire unit is placed on a platform. When the antibacterial glass is dropped and falls to the ground, the outer frame is the first to be impacted. This causes the upper and lower connecting columns at the four corners of the inner wall to be forced towards the center column, thereby compressing and deforming multiple compression springs. This causes the rotating axis to move away from the center, causing the corresponding pressure rods and air rods to slide. This also causes the piston to compress the air inside the air rod, absorbing the kinetic energy in the vertical direction, thereby reducing the impact force of the falling glass substrate and achieving the purpose of protecting the glass substrate.

[0020] 2. In this invention, by activating the ultraviolet regeneration lamp and energizing the electrically stimulated conductive wire, the self-repairing polymer layer and the antibacterial active layer begin to self-repair under the influence of the heating current within the stimulated conductive wire and the heat generated by the ultraviolet regeneration lamp. Simultaneously, GO in the antibacterial active layer physically destroys the bacterial cell membrane + Ag. + Chemical sterilization, with synergistic effects, significantly improves antibacterial efficiency, achieving self-repair capabilities and multiple antibacterial effects, enhancing antibacterial performance and coating lifespan, and reducing the frequency of manual cleaning and maintenance costs.

[0028] 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.

[0029] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 An embodiment of this utility model is provided: an antibacterial glass with a self-healing composite coating, including a glass substrate 1, a covering layer 4 fixedly connected to the outer wall of the glass substrate 1, an outer frame 3 fixedly connected to the outer wall of the covering layer 4, a plurality of lower connecting columns 12 fixedly connected to the bottom of the inner wall of the outer frame 3, a plurality of upper connecting columns 5 fixedly connected to the top of the inner wall of the outer frame 3, a central column 10 slidably connected to the top of the lower connecting columns 12, a compression spring 11 fixedly connected to the top and bottom of the central column 10, a plurality of connecting rods 13 rotatably connected to the adjacent side of the upper connecting columns 5 and the lower connecting columns 12, a rotating shaft 9 rotatably connected to the adjacent end of the connecting rod 13, a pressure rod 7 fixedly connected to the outer wall of the rotating shaft 9, a piston 8 fixedly connected to the top of the pressure rod 7, a gas rod 6 slidably connected to the outer wall of the pressure rod 7, and a repair mechanism 2 fixedly connected to the inner wall of the outer frame 3. The repair mechanism 2 is used to help the glass substrate 1 accelerate self-repair.

[0030] Specifically, the outer wall of the glass substrate 1 is fixedly connected to the cladding layer 4, and the outer wall of the cladding layer 4 is further fixedly connected to an outer frame 3. The cladding layer 4 is made of flexible material to avoid the glass substrate 1 being directly and rigidly connected to the outer frame 3, which would damage the connection of the glass substrate 1. The top of the lower connecting column 12 is slidably connected to a central column 10. The top and bottom of the central column 10 are fixedly connected to a compression spring 11. The presence of the compression spring 11 provides a certain elasticity and buffering capacity for the entire structure, which can absorb some of the impact force when subjected to external force, thereby protecting the glass substrate 1 from damage. Several connecting rods 13 are rotatably connected to the adjacent side of the upper connecting column 5 and the lower connecting column 12. These connecting rods 13 play the role of transmitting force. The top of the pressure rod 7 is fixedly connected to the piston 8, and the outer wall of the pressure rod 7 is slidably connected to the air rod 6. This design allows the air rod 6 to slide freely within a certain range, which can resist external impact and pressure.

[0031] Please see the appendix Figure 1 and attached Figure 5 The repair mechanism 2 includes an ultraviolet regeneration lamp 205. The outer wall of the ultraviolet regeneration lamp 205 is fixedly connected to the front and rear sides of the outer frame 3. An adhesion layer 204 is fixedly connected to both the front and rear sides of the glass substrate 1. A self-healing polymer layer 203 is fixedly connected to the side of the adhesion layer 204 that is far away from the front. An electrically stimulating conductive wire 201 is provided on the inner wall of the self-healing polymer layer 203. An antibacterial active layer 202 is fixedly connected to the side of the self-healing polymer layer 203 that is far away from the front.

[0032] Specifically, the adhesion layer 204 is made of modified silane or polymer binder, with a thickness of 1-5 μm, enhancing the bonding between the coating and the glass. The glass substrate 1 is ultra-white, high-transparency tempered glass, ensuring transparency and mechanical strength. The self-healing polymer layer 203 has a thickness of 20-50 μm, containing a polyurethane matrix with reversible disulfide and hydrogen bond networks, and incorporates reduced graphene sheets to form conductive pathways, enabling it to heal scratches at 50–60℃ or under UV irradiation. The antibacterial active layer 202 has a thickness of 5-10 μm, composed of a GO-Ag composite and a small amount of TiO2. The AgNPs have a diameter of 5-20 nm and are uniformly anchored on the GO surface, possessing a triple mechanism of physical puncture, chemical sterilization, and photocatalysis. The electrically stimulated conductive wire 201 combines with the GO conductive network, enabling uniform Joule heating and electric field sterilization under low pressure. The UV regeneration lamp 205 has a built-in UV-A / UV-C light source, periodically promoting polymer chain recombination and Ag... + To restore and revert to its antibacterial properties.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The top of the positioning plate 15 is provided with a positioning hole 14. Anti-collision cotton 18 is fixedly connected to the four corners of the outer wall of the outer frame 3. The bottom of the glass substrate 1 is fixedly connected with a lower protective film 19. The outer walls of the pressure rod 7 and the air rod 6 are slidably connected with a fixing bracket 20. The outer wall of the piston 8 is slidably connected to the inner wall of the air rod 6.

[0034] Specifically, a nameplate 17 is fixedly connected to the top right side of the outer frame 3. The nameplate 17 is marked with the relevant brand, model and production date information of the product so that users can identify and understand the product. The positioning hole 14 is used to achieve precise positioning. In order to protect the device from damage during transportation and use, anti-collision cotton 18 is fixedly connected to the four corners of the outer wall of the outer frame 3. These anti-collision cotton 18 can effectively absorb external impact force and reduce the damage to the device from collisions.

[0035] Please see the appendix Figure 1 and attached Figure 2 A controller 16 is fixedly connected to the top left side of the outer frame 3, a nameplate 17 is fixedly connected to the top right side of the outer frame 3, multiple positioning plates 15 are fixedly connected to the outer wall of the outer frame 3, and a protective cover 21 is fixedly connected to the outer wall of the ultraviolet regeneration lamp 205.

[0036] Specifically, multiple positioning plates 15 are fixedly connected to the outer wall of the outer frame 3. The function of these positioning plates 15 is to ensure that the various components inside the device can be accurately positioned and fixed. The controller 16 adopts the FT62E133-RB model. The controller 16 is responsible for the operation and control of the ultraviolet regeneration lamp 205. The protective cover 21 is used to protect the ultraviolet regeneration lamp 205.

[0037] Working principle: During normal operation, the entire unit is placed on a platform. The surface of the glass substrate 1 is coated with a self-healing coating. When the antibacterial glass is dropped and falls to the ground, the outer frame 3 is slightly higher than the glass substrate 1, so the outer frame 3 is the first to be impacted. The impact force on the outer frame 3 causes the upper connecting column 5 and the lower connecting column 12 at the four corners of the inner wall of the outer frame 3 to be forced towards the center column 10, thereby causing multiple compression springs 11 to be compressed and deformed. As the upper connecting column 5 and the lower connecting column 12 are forced to move closer together, multiple connecting rods 13 are forced to rotate away from the center, driving the rotating shaft 9 to move away from the center. This causes the corresponding pressure rod 7 and air rod 6 to slide, and drives the piston 8 to compress the air inside the air rod 6, absorbing the kinetic energy of the upper connecting column 5 and the lower connecting column 12, thereby reducing the impact force of the glass substrate 1 falling and protecting the glass substrate 1.

[0038] When the outer surface of the glass substrate 1 is damaged, the ultraviolet regeneration lamp 205 is activated simultaneously, and the electrical stimulation conductive wire 201 is energized. This causes the self-healing polymer layer 203 to heat up and begin self-repair under the stimulation of the current in the electrical stimulation conductive wire 201. Simultaneously, the antibacterial active layer 202 also begins self-repair under the action of the ultraviolet regeneration lamp 205 and the resulting heat. Furthermore, the electrical stimulation and photocatalysis assist in improving the sterilization rate and depth. Additionally, the GO within the antibacterial active layer 202 physically disrupts the bacterial cell membrane + Ag. + Chemical sterilization, with synergistic effects, significantly improves antibacterial efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
