Description

Technical Field

[0001] The present invention relates to the technical field of PVC film production, in particular to a PVC film surface anti-mildew treatment production and processing device and a preparation process and product thereof. Background Art

[0002] PVC film is primarily composed of polyvinyl chloride (PVC), with other ingredients added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is lacquer, the middle is primarily composed of PVC, and the bottom layer is a backing adhesive. PVC, abbreviated as PVC, is a polymer formed by free radical polymerization of vinyl chloride monomer (VCM) with initiators such as peroxides and azo compounds, or under the influence of light or heat. Vinyl chloride homopolymers and copolymers are collectively referred to as vinyl chloride resins.

[0003] However, the existing PVC film often has incomplete disinfection and sterilization during the production and sterilization process. Once the humidity of the environment in which the film is stored changes, mold and bacteria will appear on the surface of the film. Therefore, it does not meet the existing needs.

[0014] A preparation process of a PVC film surface anti-mildew treatment production and processing device comprises the following steps:

[0015] Step 1: Place the formed PVC film roll on the feed rack, and use the motor structure outside the feed rack to realize the conveying and supply of the film material. The film pulled out from the feed rack needs to pass between the targeting guide frame and the coating base plate;

[0016] Step 2: Before the upper surface of the film passes through the targeting guide, it needs to be pre-treated by the pre-treatment unit to perform a preliminary surface cleaning. Then the film moves down to the surface of the magnetic plate at the bottom of the targeting guide. The magnetic plate will move rapidly along the track structure on both sides.

[0017] Step 3: As the magnetic plate moves at high speed, the target plate directly below the magnetic plate sprays the silver ion plating solution onto the lower surface of the film. The sprayed silver ions are affected by the magnetic plate and adsorbed onto the surface of the film.

[0018] Step 4: After the coating is completed, the PVC film is stretched to the film surface cleaning unit, and the lower surface of the coating is polished and cleaned with the help of the film surface cleaning unit. After cleaning and disinfection, it can be rolled up and stored.

[0019] In addition, the present invention also provides a PVC film with a surface anti-mildew treatment prepared by the preparation process, wherein the silver ion plating solution is sprayed on the lower surface of the PVC film, and the unsprayed upper surface of the PVC film serves as a winding surface.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention sets the formed PVC film roll on the feeding rack, and uses the motor structure outside the feeding rack to realize the conveying and supply of the film material. The film body pulled out from the feeding rack needs to pass between the targeting guide frame and the coating seat plate. When the film contacts the magnetic plate at the bottom of the targeting guide frame, the magnetic plate will move rapidly along the track structure on both sides. During the high-speed movement of the magnetic plate, the target plate surface directly below the magnetic plate will spray the silver ion plating solution on the lower surface of the film. The sprayed silver ions will be affected by the magnetic plate and adsorbed on the surface of the film. Finally, the unsprayed upper surface is used as the winding surface. The film surface exposed on the outer ear can play an antibacterial role after silver ion coating, thereby avoiding the formation of mildew.

[0022] 2. In the present invention, a silver ion plating solution is stored inside a plating solution tank. The liquid can be splashed onto the surface of the film in a polymeric manner through a pump body. The free silver ions can be attached to the surface of the film in conjunction with a magnetic structure, thereby forming a protective layer to play an antibacterial and antimicrobial role. The chemical structure of silver determines that silver has a high catalytic ability. The reduction potential of highly oxidized silver is extremely high, which is sufficient to generate atomic oxygen in the space around it. Atomic oxygen has strong oxidizing properties and can sterilize. Ag+ can strongly attract the sulfhydryl group on the protease in the bacterial body and quickly combine with it, causing the protease to lose its activity and leading to the death of the bacteria.

[0036] A preparation process of a PVC film surface anti-mildew treatment production and processing device comprises the following steps:

[0037] Step 1: Place the formed PVC film roll on the feeding rack 2, and use the motor structure outside the feeding rack 2 to realize the conveying and supply of the film material. The film pulled out from the feeding rack 2 needs to pass between the targeting guide frame 4 and the coating base plate 5;

[0038] Step 2: Before the upper surface of the film passes through the targeting guide 4, it needs to be pre-cleaned by the pre-treatment unit 7. Then the film moves down to the surface of the magnetic plate 406 at the bottom of the targeting guide 4. The magnetic plate 406 will move rapidly along the track structure on both sides.

[0039] Step 3: As the magnetic plate 406 moves at high speed, the surface of the target plate 503 directly below the magnetic plate 406 sprays the silver ion plating solution onto the lower surface of the film. The sprayed silver ions are affected by the magnetic plate 406 and adsorbed onto the surface of the film.

[0040] Step 4: After the coating is completed, the PVC film is stretched to the film surface cleaning unit 6, and the lower surface of the coating is polished and cleaned by the film surface cleaning unit 6. After cleaning and disinfection, it can be rolled up and stored.

[0041] In summary, the formed PVC film roll is put on the feeding rack 2, and the motor structure outside the feeding rack 2 is used to realize the conveying and supply of the film material. The film body pulled out from the feeding rack 2 needs to pass between the targeting guide rack 4 and the coating seat plate 5. Before the upper surface of the film passes through the targeting guide rack 4, it needs to be preliminarily cleaned by the pretreatment unit 7. Then the film moves down to the surface of the magnetic plate 406 at the bottom of the targeting guide rack 4. The magnetic plate 406 will move rapidly in a cycle along the track structures on both sides. During the high-speed movement of the magnetic plate 406, the surface of the target plate 503 directly below the magnetic plate 406 will spray the silver ion plating solution on it. On the lower surface of the film, the chemical structure of silver determines that silver has a high catalytic ability. The reduction potential of highly oxidized silver is extremely high, which is enough to produce atomic oxygen in the space around it. Atomic oxygen has strong oxidizing properties and can sterilize. Ag+ can strongly attract the sulfhydryl groups on the protease in the bacteria and quickly combine with it, causing the protease to lose its activity and leading to the death of the bacteria. The sprayed silver ions will be affected by the magnetic plate 406 and adsorbed on the surface of the film. After the coating is completed, the PVC film is stretched to the membrane surface cleaning unit 6, and the membrane surface cleaning unit 6 is used to polish and clean the lower surface of the coating. After cleaning and disinfection, it can be rolled up and stored.

[0042] The PVC material of the product of this embodiment adopts the following new formula of antistatic PVC super-transparent film material: 60-80% PVC powder, 10-15% transparent powder ST600, 1-4% barium zinc composite stabilizer, 1-4% epoxidized soybean oil, 2-10% dioctyl adipate, 5-15% fatty acid PEG monoester, 0.1-0.5% ACR, 0.5-5% paraffin, and the balance is dioctyl p-xylene dioctyl ester.

[0043] It has the characteristics of long-lasting antistatic properties, high transparency, and good mechanical properties. Among them, transparent powder ST600 is used to replace part of PVC, and epoxy soybean oil / dioctyl phthalate is used as a composite plasticizing system to increase the plasticizing effect and reduce the amount of plasticizer, solving the problem of easy precipitation of the antistatic system. Fatty acid PEG monoester is added as an antistatic agent to achieve long-lasting antistatic properties. A high-precision thickness-adjustable four-roll calender has been developed. The middle roller of the calender adopts an axis cross design, and the lower roller of the discharge is in a drum shape and can be pre-bent. In conjunction with the automatic distance adjustment system, the calender roller distance adjustment device is automatically adjusted to correct the thickness deviation of the two points on the left and right of the calender. The lateral thickness deviation of the film is controlled by manually controlling the axis crossing device and the pre-bending device, thereby realizing the calendering molding process of ultra-transparent films with a thickness of less than 0.08mm. A multiple filtration and plasticizing process has been developed, and multi-layer filter screens of 20 mesh, 60 mesh, 120 mesh, 150 mesh, and 200 mesh are set in the filter in sequence to avoid the formation of fish eyes and crystal points. The product has high transparency and long-lasting antistatic properties.

[0045] 1. Appearance quality: no crystal points, flow marks, perforations, bubbles, uniform thickness and smoothness:

[0046] 2. Tensile strength: longitudinal ≥16.0MPa, transverse ≥16.0MPa;
