Description

Technical Field

[0001] This application belongs to the technical field of PE film, and particularly relates to a highly ductile, light-blocking PE film. Background Technology

[0002] PE film is the simplest structural polymer organic compound and the most widely used polymer material in the world today.

[0003] A Chinese patent with publication number CN111469520B discloses a rust-proof and anti-fog PE shrink film and its processing method. The rust-proof and anti-fog PE shrink film comprises an outer layer, a middle layer, and an inner layer from the outside to the inside. The outer layer is made from raw materials comprising the following parts by weight: 350-550 parts LDPE, 150-300 parts HDPE, 150-300 parts mLLDPE, 10-30 parts matting agent, 5-15 parts silica, and 10-30 parts compatibilizer. The middle layer is made from raw materials comprising the following parts by weight: 400-600 parts LDPE, 150-300 parts HDPE, 150-300 parts mLLDPE, 100-200 parts rust inhibitor, 15-35 parts matting agent, and 10-30 parts compatibilizer. The matting agent is a fluorinated elastomer.

[0004] The above invention has excellent anti-rust and anti-fogging properties. However, the PE film is easily damaged by external forces during use, and its high light transmittance makes it inconvenient for users. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a highly stretchable, light-blocking PE film that has high stretchability, excellent light-blocking performance, is not easily damaged by external forces, and is convenient for users.

[0006] This application provides a highly elastic, light-transmitting PE film, comprising a film body, wherein the film body includes:

[0007] The inner layer includes the mucosa and the extensor membrane;

[0008] The middle layer includes a light-blocking film;

[0009] The outer layer includes a wear-resistant film;

[0010] The adhesive film and the extended film are bonded together, the light-shielding film is placed between the inner and outer layers, and the wear-resistant film and the light-shielding film are bonded together. The adhesive film is made of polyvinyl alcohol, the extended film is made of carbon fiber, the light-shielding film is made of high-density polyethylene, and the wear-resistant film is made of polyimide.

[0011] In this technical solution, an inner layer, a middle layer, and an outer layer are set in the membrane body. The inner layer contains an adhesive film and an extended film, which are bonded together. The adhesive film is made of polyvinyl alcohol, and the extended film is made of carbon fiber. The adhesive film facilitates the bonding work of the inner layer of the membrane body, making it easier for the membrane body to protect the workpiece. The extended film effectively improves the ductility of the membrane body, making it less susceptible to damage from external forces and convenient for users. The middle layer contains a light-blocking film, which is placed between the inner and outer layers. The light-blocking film is made of high-density polyethylene and has excellent light-blocking properties, effectively enhancing the light-blocking performance of the membrane body and making it convenient for users. The outer layer contains a wear-resistant film, which is bonded to the light-blocking film. The wear-resistant film is made of polyimide and improves the wear resistance of the membrane body surface, effectively extending the service life of the membrane body.

[0012] Furthermore, the mucosa is provided with a protective film;

[0013] The protective film is made of metal foil.

[0014] In this technical solution, by setting a protective film in the mucosa, and the protective film being made of metal foil, when the operator uses the membrane body, the protective film on the mucosa is peeled off, and then the mucosa is covered on the object. The protective film can reduce the impact of the external environment on the mucosa and ensure the working performance of the membrane body.

[0015] Furthermore, the membrane body is provided with waterproof tape;

[0016] The waterproof tape is placed on both sides of the outer layer.

[0017] In this technical solution, by setting waterproof tape in the membrane body and placing the waterproof tape on both sides of the outer layer, when the membrane body is applied to a larger object, the width of the membrane body is insufficient and the protection effect is not good. The waterproof tape makes it easier to splice the membrane bodies together and makes it easier for the membrane body to be applied to larger objects.

[0018] Furthermore, the wear-resistant film contains nylon powder.

[0019] In this technical solution, by setting nylon powder inside the wear-resistant membrane, the nylon powder can effectively enhance the strength of the wear-resistant membrane, making the wear-resistant membrane more durable and maintaining excellent wear resistance, thus further extending the service life of the membrane body.

[0020] Furthermore, the outer layer is coated with an anti-ultraviolet agent.

[0021] In this technical solution, by applying an anti-ultraviolet agent to the outer layer, the anti-ultraviolet agent can effectively enhance the anti-ultraviolet performance of the membrane body, reduce the impact of ultraviolet rays on the protected object, and prevent ultraviolet rays from damaging the light-blocking membrane, thereby further enhancing the light-blocking performance of the membrane body.

[0022] Furthermore, the inner layer is coated with an antibacterial agent.

[0023] In this technical solution, by applying an antibacterial agent to the inner layer, the antibacterial agent can effectively enhance the antibacterial properties of the inner layer. When the membrane body is applied, it can effectively reduce the probability of bacteria growing on the contact surface of the protected object, thereby enhancing the protective effect of the membrane body.

[0024] The beneficial effects of this application are:

[0025] 1. The adhesive film and the extended film are bonded together. The adhesive film is made of polyvinyl alcohol, and the extended film is made of carbon fiber. The adhesive film facilitates the bonding of the inner layer of the membrane body, which is convenient for the membrane body to protect the workpiece. The extended film effectively improves the extensibility of the membrane body, making it less susceptible to damage from external forces and convenient for users.

[0026] 2. A light-blocking film is placed between the inner and outer layers. The light-blocking film is made of high-density polyethylene and has excellent light-blocking properties, which effectively enhances the light-blocking performance of the film itself.

[0027] 3. The wear-resistant film and the light-shielding film are bonded together. The wear-resistant film is made of polyimide, which improves the wear resistance of the film body surface and effectively extends the service life of the film body. Attached Figure Description

[0033] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0034] Example 1:

[0035] like Figure 1 and Figure 2 As shown, this application provides a high-strength, light-transmitting PE film, including a film body 100, the film body 100 comprising:

[0036] The inner layer 200 includes a mucosa 210 and an extension membrane 220;

[0037] The middle layer 300 includes the light-shielding film 310;

[0038] The outer layer 400 includes a wear-resistant film 410;

[0039] The adhesive film 210 is bonded to the extended film 220, the light-shielding film 310 is placed between the inner layer 200 and the outer layer 400, and the wear-resistant film 410 is bonded to the light-shielding film 310. The adhesive film 210 is made of polyvinyl alcohol, the extended film 220 is made of carbon fiber, the light-shielding film 310 is made of high-density polyethylene, and the wear-resistant film 410 is made of polyimide.

[0040] By providing an inner layer 200, a middle layer 300, and an outer layer 400 in the membrane body 100, the inner layer 200 contains an adhesive membrane 210 and an extension membrane 220, which are bonded together. The adhesive membrane 210 is made of polyvinyl alcohol, and the extension membrane 220 is made of carbon fiber. The adhesive membrane 210 facilitates the bonding of the inner layer 200 of the membrane body 100, making it easier for the membrane body 100 to protect the workpiece. The extension membrane 220 effectively improves the ductility of the membrane body 100, making it less susceptible to damage from external forces and convenient for users. The middle layer 300... The membrane body 100 is provided with a light-blocking film 310, which is placed between the inner layer 200 and the outer layer 400. The light-blocking film 310 is made of high-density polyethylene and has excellent light-blocking properties, which effectively enhances the light-blocking performance of the membrane body 100 and facilitates user use. The outer layer 400 is provided with a wear-resistant film 410, which is bonded to the light-blocking film 310. The wear-resistant film 410 is made of polyimide and improves the wear resistance of the surface of the membrane body 100, effectively extending the service life of the membrane body 100.

[0041] Furthermore, the mucosa 210 is provided with a protective film 211;

[0042] The protective film 211 is made of metal foil.

[0043] By setting a protective film 211 in the mucosa 210, and the protective film 211 is made of metal foil, when the operator uses the membrane body 100, he peels off the protective film 211 on the mucosa 210 and then covers the mucosa 210 on the object. The protective film 211 can reduce the impact of the external environment on the mucosa 210 and ensure the working performance of the membrane body 100.

[0044] Furthermore, the membrane body 100 is provided with waterproof tape 110;

[0045] The waterproof tape 110 is placed on both sides of the outer layer 400.

[0046] By setting waterproof tape 110 in the membrane body 100 and placing the waterproof tape 110 on both sides of the outer layer 400, when the membrane body 100 is applied to a larger object, the width of the membrane body 100 is insufficient and the protection effect is not good. The waterproof tape 110 makes it easier to splice the membrane body 100 together and makes it easier for the membrane body 100 to be applied to a larger object.

[0047] Example 2:

[0048] like Figure 1 and Figure 2 As shown, this application provides a highly ductile, light-blocking PE film, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The wear-resistant film 410 has nylon powder disposed inside it.

[0049] By incorporating nylon powder inside the wear-resistant membrane 410, the nylon powder effectively enhances the strength of the wear-resistant membrane 410, making the wear-resistant membrane 410 more durable and maintaining excellent wear resistance, thus further extending the service life of the membrane body 100.

[0050] Furthermore, the outer layer 400 is coated with an anti-ultraviolet agent.

[0051] By applying an anti-ultraviolet agent to the outer layer 400, the anti-ultraviolet agent can effectively enhance the anti-ultraviolet performance of the membrane body 100, reduce the impact of ultraviolet rays on the protected object, and prevent ultraviolet rays from damaging the light-blocking film 310, further enhancing the light-blocking properties of the membrane body 100.

[0052] Furthermore, the inner layer 200 is coated with an antibacterial agent.

[0053] By applying an antibacterial agent to the inner layer 200, the antibacterial agent can effectively enhance the antibacterial properties of the inner layer 200. When the membrane body 100 is applied, it can effectively reduce the probability of bacteria growing on the contact surface of the protected object, thereby enhancing the protective effect of the membrane body 100.
