Description

Technical Field

[0001] This invention belongs to the field of opening and closing curtain track technology, and particularly relates to a modular opening and closing curtain track based on antibacterial composite material. Background Technology

[0002] Curtains are widely used as common objects for both privacy and decoration in various settings, including daily life, medical facilities, and public activity areas.

[0003] However, traditional curtain tracks only provide basic support and opening / closing functions, and cannot effectively inhibit viruses and bacteria attached to the tracks and curtains. In environments with frequent personnel movement, bacteria and viruses can easily breed and spread on curtains and their tracks, thereby increasing the risk of infectious disease transmission and threatening people's health. Summary of the Invention

[0004] The purpose of this invention is to address the problem that traditional curtain tracks only provide basic support and opening / closing functions, failing to effectively inhibit viruses and bacteria attached to the track and curtain body. In environments with frequent personnel movement, bacteria and viruses easily breed and spread on curtains and their tracks, increasing the risk of infectious disease transmission and threatening people's health. Therefore, this invention proposes a modular curtain track based on antibacterial composite materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular opening and closing curtain track based on antibacterial composite material, comprising an aluminum extrusion profile and an antibacterial resin profile, wherein the antibacterial resin profile is located on the inner wall of the aluminum extrusion profile, and wherein the antibacterial resin profile comprises the following components by weight percentage:

[0006] High-performance resin 50-80%;

[0007] Antibacterial agent 10-30%;

[0008] Lubricant 1-3%;

[0009] Dispersant 2-5%;

[0010] Stabilizer 0.5-2%;

[0011] Antioxidant 0.5-2%.

[0012] Furthermore, the aforementioned antibacterial agent comprises nano-sized silver ion particles and natural plant extracts, wherein the natural plant extracts are at least one of tea polyphenols and baicalin.

[0013] Furthermore, the particle size of the aforementioned nanoscale silver ion particles is 1~100nm.

[0014] Furthermore, the dispersant is at least one of polyvinylpyrrolidone and sodium dodecyl sulfate.

[0015] Furthermore, the aforementioned stabilizer is at least one of hindered amine light stabilizers and phosphite stabilizers.

[0016] Furthermore, the aforementioned high-performance resin is any one of polypropylene, polyethylene, and polycarbonate.

[0017] Furthermore, the present invention also provides a method for manufacturing a modular opening and closing curtain track based on antibacterial composite material, comprising the following steps:

[0018] S1: Raw material pretreatment; Place the high-performance resin in a drying oven and dry it at 80-100℃ for 2-4 hours to remove moisture from the resin; Weigh the antibacterial agent, the dispersant, the stabilizer, the lubricant and the antioxidant in the specified proportions, and grind them separately to make the particle size of each component uniform, so as to facilitate subsequent mixing;

[0019] S2: Mixing and stirring; add the dried high-performance resin to a high-speed mixer and start the mixer to stir for 2-5 minutes; add the ground antibacterial agent, the dispersant, the stabilizer, the lubricant and the antioxidant in sequence, and continue stirring for 10-20 minutes to ensure that all components are fully mixed and uniform to form an antibacterial resin mixture; conduct antibacterial performance tests and light exposure tests on the antibacterial resin mixture.

[0020] S3: Melt extrusion; The well-mixed antibacterial resin mixture is added to a twin-screw extruder, the twin-screw extruder is started, and the antibacterial resin mixture is melted and plasticized under the rotation of the screws, and then extruded through the die head to form an antibacterial resin profile;

[0021] S4: Cooling and shaping. The extruded antibacterial resin profile is immediately cooled through a cooling water tank to quickly shape the profile and prevent deformation.

[0022] S5: Cutting and shaping. According to the design dimensions of the opening and closing curtain track, use a cutting machine to cut the cooled and shaped antibacterial resin profile into the required length;

[0023] S6: Track assembly, where the cut antibacterial resin profiles are attached to the inner wall of the aluminum extrusion profiles using clips or adhesive.

[0024] This invention provides a modular opening and closing curtain track based on antibacterial composite material. The antibacterial resin profile uses high-performance resin as the matrix, and a dispersant is used to uniformly disperse nano-sized silver ion particles (1~100nm) and natural plant extracts such as tea polyphenols / baicalin, forming a highly efficient antibacterial network. Silver ions penetrate bacterial cell membranes and disrupt metabolism, while plant extracts inhibit biofilm formation, achieving antibacterial effects synergistically. Stabilizers and antioxidants respectively resist photo-oxidation and thermal aging, protecting antibacterial activity and resin structure. Lubricants optimize processing flowability, ensuring the profile is dense and defect-free. Finally, the antibacterial resin profile is embedded in the inner wall of an aluminum extrusion profile, utilizing the high strength and corrosion resistance of aluminum to provide structural support, forming a modular track that is rigid on the outside and tough on the inside. This ensures long-term antibacterial durability while achieving convenient installation and stable use. When bacteria or viruses come into contact with the surface of the opening and closing curtain track, the nano-silver ion particles and natural plant extracts in the antibacterial resin profile will quickly take effect, destroying the cell structure or biofilm of bacteria or viruses and inhibiting their growth or reproduction.

[0025] In the manufacturing process, the high-performance resin is first dried to remove moisture and prevent defects caused by moisture vaporization during processing. At the same time, antibacterial agents and other additives are ground to achieve uniform particle size and ensure their dispersion effect in the resin. Then, the mechanical shear force of a high-speed mixer is used to gradient mix the dried resin and the ground additives to form an antibacterial resin mixture with uniform distribution of antibacterial agents and synergistic effect of various functional additives. The antibacterial and stability of the composite system are verified through performance testing. Next, the mixture is melted and plasticized by the screw rotation of a twin-screw extruder, so that the antibacterial components are fully integrated with the resin matrix. The mixture is then extruded through the die head to form a continuous profile. After being quickly shaped in a cooling water tank to prevent deformation, the profile is cut to the design size and assembled onto the inner wall of the aluminum extrusion profile by snap-fit ​​or adhesive method, ultimately producing an opening and closing curtain track with both stable structure and long-lasting antibacterial performance.

[0026] Therefore, this embodiment has the following advantages compared to the prior art:

[0027] A modular curtain track based on antibacterial composite materials solves the problem that traditional curtain tracks only have basic support and opening / closing functions, and cannot effectively inhibit viruses and bacteria attached to the track and curtain body. In environments with frequent personnel movement, bacteria and viruses can easily breed and spread on curtains and their tracks, thereby increasing the risk of infectious disease transmission and threatening people's health.

[0042] Example 1

[0043] Please see Figure 1-5 This invention provides a technical solution: a modular opening and closing curtain track based on antibacterial composite material, comprising an aluminum extrusion profile 1 and an antibacterial resin profile 2, wherein the antibacterial resin profile 2 is located on the inner wall of the aluminum extrusion profile 1, and wherein the antibacterial resin profile 2 comprises the following components by weight percentage:

[0044] High-performance resin 50-80%;

[0045] Antibacterial agent 10-30%;

[0046] Lubricant 1-3%;

[0047] Dispersant 2-5%;

[0048] Stabilizer 0.5-2%;

[0049] Antioxidant 0.5-2%.

[0050] Specifically, see Figure 1-5The antibacterial agent comprises nano-sized silver ion particles and natural plant extracts, wherein the natural plant extracts are at least one of tea polyphenols and baicalin. The nano-silver ions kill viruses through contact, and light exposure may accelerate the release of silver ions or alter their form (such as the formation of silver oxide).

[0051] Specifically, see Figure 1-5 The nanoscale silver ion particles have a particle size of 1~100nm.

[0052] This invention provides a modular opening and closing curtain track based on antibacterial composite material. The antibacterial resin profile uses high-performance resin as the matrix, and a dispersant is used to uniformly disperse nano-sized silver ion particles (1~100nm) and natural plant extracts such as tea polyphenols / baicalin, forming a highly efficient antibacterial network. Silver ions penetrate bacterial cell membranes and disrupt metabolism, while plant extracts inhibit biofilm formation, achieving antibacterial effects synergistically. Stabilizers and antioxidants respectively resist photo-oxidation and thermal aging, protecting antibacterial activity and resin structure. Lubricants optimize processing flowability, ensuring the profile is dense and defect-free. Finally, the antibacterial resin profile is embedded in the inner wall of an aluminum extrusion profile, utilizing the high strength and corrosion resistance of aluminum to provide structural support, forming a modular track that is rigid on the outside and tough on the inside. This ensures long-term antibacterial durability while achieving convenient installation and stable use. When bacteria or viruses come into contact with the surface of the opening and closing curtain track, the nano-silver ion particles and natural plant extracts in the antibacterial resin profile will quickly take effect, destroying the cell structure or biofilm of bacteria or viruses and inhibiting their growth or reproduction.

[0053] In the manufacturing process, the high-performance resin is first dried to remove moisture and prevent defects caused by moisture vaporization during processing. At the same time, antibacterial agents and other additives are ground to achieve uniform particle size and ensure their dispersion effect in the resin. Then, the mechanical shear force of a high-speed mixer is used to gradient mix the dried resin and the ground additives to form an antibacterial resin mixture with uniform distribution of antibacterial agents and synergistic effect of various functional additives. The antibacterial and stability of the composite system are verified through performance testing. Next, the mixture is melted and plasticized by the screw rotation of a twin-screw extruder, so that the antibacterial components are fully integrated with the resin matrix.

[0054] Therefore, this embodiment has the following advantages compared to the prior art:

[0055] A modular curtain track based on antibacterial composite materials solves the problem that traditional curtain tracks only have basic support and opening / closing functions, and cannot effectively inhibit viruses and bacteria attached to the track and curtain body. In environments with frequent personnel movement, bacteria and viruses can easily breed and spread on curtains and their tracks, thereby increasing the risk of infectious disease transmission and threatening people's health.

[0056] Example 2:

[0057] See Figure 1-5 The figure shows a modular opening and closing curtain track based on antibacterial composite material provided in Embodiment 2 of the present invention. This embodiment further improves upon the above embodiments by employing the following technical solution: the dispersant is at least one of polyvinylpyrrolidone and sodium dodecyl sulfate. This ensures that the nano-sized silver ion particles and natural plant extracts are uniformly dispersed in the resin matrix.

[0058] The stabilizer is at least one of hindered amine light stabilizers and phosphite stabilizers. It is used to prevent the antiviral and antibacterial components from degrading or becoming ineffective during long-term use. The antioxidant is used to inhibit oxidation reactions of the resin caused by factors such as air, light, and high temperature during use.

[0059] Example 3:

[0060] See Figure 1-5 The figure shows a modular opening and closing curtain track based on antibacterial composite material provided in Embodiment 3 of the present invention. Based on the above embodiments, the following technical solutions are further improved: the high-performance resin is any one of polypropylene, polyethylene, and polycarbonate.

[0061] Polypropylene (PP) possesses excellent mechanical strength, toughness, and chemical resistance, along with low density and light weight. When used to manufacture curtain tracks, it ensures that the track is not easily deformed or broken when bearing the weight of the curtains and during daily pulling, while also reducing the overall weight of the track for easier installation and handling.

[0062] Polyethylene (PE): Divided into low-density polyethylene (LDPE) and high-density polyethylene (HDPE). LDPE has good flexibility, while HDPE has higher strength. The choice depends on the specific requirements of the track; generally, it provides good flexibility and a certain level of strength, allowing the track to maintain its shape stability under different environments.

[0063] Polycarbonate (PC): It has excellent impact strength, transparency, and heat resistance. Tracks made from PC are not only sturdy and durable, able to withstand large external impacts without breaking, but also aesthetically pleasing. PC is an ideal choice for tracks that require a transparent or semi-transparent effect, and its heat resistance ensures that the tracks will not soften or deform at high temperatures.

[0064] Example 4:

[0065] See Figure 1-5 The figure shows a method for manufacturing a modular opening and closing curtain track based on antibacterial composite material according to Embodiment 3 of the present invention. This embodiment further improves upon the above embodiments by providing the following technical solution: A method for manufacturing a modular opening and closing curtain track based on antibacterial composite material includes the following steps:

Perform antibacterial performance testing and light exposure testing on the antibacterial resin mixture; the curtain track is installed near the window, exposed to natural light during the day and in darkness at night; the light and dark test can simulate environmental conditions at different time periods to verify the persistence of the antiviral effect in actual use.

[0068] For bacterial testing, bacteria are cultured in a bacterial culture dish and then placed on the test specimen for testing. The test period for bacteria is 24 hours, and for mold it is 4 days. Observe whether there is a barrier band forming around the test specimen.

[0069] In the light test, the ordinary resin track and the antibacterial resin track were tested separately in bright and dark environments; over time, the ordinary resin track showed severe discoloration, while the antibacterial resin track did not change color.

[0070] S3: Melt extrusion; The mixed antibacterial resin mixture is added to a twin-screw extruder, the twin-screw extruder is started, and the antibacterial resin mixture is melted and plasticized under the rotation of the screws, and then extruded through the die head to form the antibacterial resin profile 2;
