A flexible antistatic protective film

Abstract

This utility model discloses a flexible antistatic protective film, relating to the field of antistatic protective films. The utility model includes a base layer, the surface of which is covered with a surface layer. The surface of the surface layer is formed into a protective surface by stamping. The protective surface is a conical array, and a conductive layer is coated on the protective surface. This utility model increases the surface roughness by forming a conical array of protective surfaces through stamping. This increased roughness makes the contact area more dispersed when the surface layer comes into contact with other objects, thereby reducing the concentration of local frictional forces and effectively reducing triboelectric effects. Simultaneously, by reducing triboelectric effects through physical structural design, it reduces reliance on traditional chemical antistatic agents. This physical method is not only environmentally friendly but also reduces the pollution and allergy problems that may arise from chemical antistatic agents.

Description

Technical Field

[0001] This utility model relates to the field of antistatic protective film, specifically a flexible antistatic protective film. Background Technology

[0002] Flexible antistatic protective film is a thin film material with added antistatic agents or treated with antistatic agents. It has good flexibility and conductivity, effectively prevents static electricity accumulation and provides comprehensive protection for items. With its high transparency, easy to stick and peel, wear resistance, dustproof and waterproof features, it is widely used in the electronics, optics, precision instruments and medical industries to protect sensitive components and equipment from static interference and dust contamination.

[0003] Most existing antistatic protective films generate static electricity through friction during use. These films struggle to effectively address the issue of static electricity generation, thus reducing their static electricity handling capabilities and ease of use. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a flexible antistatic protective film to solve the technical problem that antistatic protective films are difficult to effectively solve the problem of static electricity generation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible antistatic protective film, comprising a base layer, a surface layer attached to the surface of the base layer, a protective surface formed by stamping the surface of the surface layer, the protective surface being a conical array surface, and a conductive layer coated on the protective surface.

[0006] By adopting the above technical solution, the flexible antistatic protective film of this embodiment ensures the overall strength and stability of the protective film by setting a base layer as a supporting structure, so that it can withstand a certain amount of external force during use without being easily damaged. At the same time, a surface layer is applied to the surface of the base layer and formed into a protective surface in the form of a conical array by stamping. This unique physical structure design not only increases the roughness of the surface layer and effectively reduces the triboelectric effect, but also allows static electricity to be quickly dispersed and dissipated after it is generated through the geometric shape of the conical array surface, which greatly improves the antistatic performance of the protective film.

[0007] Furthermore, the surface layer is a polyethylene layer with a thickness of 5-10 μm, and the conical array surface has a height of 10-20 μm and a spacing of 50-100 μm.

[0008] By adopting the above technical solution, the surface layer is set to be a polyethylene layer with a thickness of 5-10μm, which not only ensures that the surface layer has sufficient thickness to provide good physical protection performance, but also avoids the decrease in flexibility and bonding difficulties caused by excessive thickness.

[0009] Furthermore, the combined light transmittance of the surface layer and the conductive layer is ≥90%, and the conductive layer is an antistatic coating.

[0010] By adopting the above technical solution, this high light transmittance allows the protective film to provide anti-static protection without obstructing the view of the protected object, making it particularly suitable for occasions requiring transparent protection.

[0011] Furthermore, an adhesive layer is coated on the other side of the base layer, which is a low-tack acrylic adhesive layer with a thickness of 3-5 μm.

[0012] By adopting the above technical solution, the adhesive layer allows the protective film to be easily pasted onto the protected object, providing good adhesion and firmness.

[0013] Furthermore, a release film is adhered to the surface of the adhesive layer.

[0014] By adopting the above technical solution, the release film effectively protects the adhesive layer from contamination or adhesion during storage and transportation, maintaining the cleanliness and stickiness of the adhesive layer.

[0015] Furthermore, the edge of the antistatic protective film is formed with several serrated grooves, and the serrated grooves are arranged linearly at equal intervals.

[0016] By adopting the above technical solution, the serrated grooves increase the flexibility of the edges. Several serrated grooves are arranged linearly at equal intervals. This regular arrangement is not only aesthetically pleasing, but also allows the protective film to effectively guide air out during the bonding process.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model uses a protective surface with a conical array of surfaces formed by stamping, which increases the surface roughness. This increased roughness makes the contact area more dispersed when the surface comes into contact with other objects, thereby reducing the concentration of local friction and effectively reducing the triboelectric effect. At the same time, by reducing triboelectric effect through physical structure design, the reliance on traditional chemical antistatic agents is reduced. This physical method is not only environmentally friendly, but also reduces the pollution and allergy problems that may be caused by chemical antistatic agents.

[0019] 2. This utility model features several equidistant linearly arranged serrated grooves along the edge of the protective film, providing an effective airflow channel during the bonding process. When the protective film is bonded, these serrated grooves act as airflow channels, guiding the squeezed air to escape quickly, preventing air bubbles from forming between the bonding surfaces, thus improving the tightness of the bond. At the same time, the equidistant linearly arranged serrated grooves ensure more uniform airflow, guaranteeing the consistency and flatness of the bonding surfaces, improving bonding efficiency and effectiveness, making the bonding process more convenient and quick, and ensuring the final performance after bonding.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1:

[0026] A flexible antistatic protective film, such as Figure 1-3 As shown, the film includes a base layer 2, a surface layer 1 attached to the surface of the base layer 2, and a protective surface 4 formed by stamping on the surface of the surface layer 1. The protective surface 4 is a conical array surface, and a conductive layer 5 is coated on the protective surface 4. In this embodiment, the flexible antistatic protective film uses the base layer 2 as a supporting structure to ensure the overall strength and stability of the protective film, so that it can withstand a certain amount of external force during use without being easily damaged. At the same time, the surface layer 1 attached to the surface of the base layer 2 and the protective surface 4 formed by stamping into a conical array surface, this unique physical structure design not only increases the surface roughness and effectively reduces the triboelectric effect, but also allows static electricity to be quickly dispersed and dissipated after it is generated through the geometry of the conical array surface, which greatly improves the antistatic performance of the protective film. In addition, the conductive layer 5 coated on the protective surface 4 further enhances the conductivity of the protective film, which can quickly conduct away the generated static electricity and prevent static electricity accumulation from damaging electronic products, etc.

[0027] See Figure 1 , Figure 2 , Figure 3 The surface layer 1 is a 5-10μm thick polyethylene layer. The conical array has a height of 10-20μm and a spacing of 50-100μm. Setting the surface layer 1 to be a 5-10μm thick polyethylene layer ensures sufficient thickness to provide good physical protection performance, while avoiding the decrease in flexibility and difficulty in bonding caused by excessive thickness. At the same time, the design of 10-20μm height and 50-100μm spacing in the conical array ensures effective roughness of the protective surface to reduce the triboelectric effect, while avoiding surface unevenness and reduced light transmittance caused by excessively high cones or excessively dense spacing. This allows the protective film to provide good antistatic performance while maintaining good appearance and light transmittance.

[0028] See Figure 1 , Figure 2 , Figure 3 The combined light transmittance of the surface layer 1 and the conductive layer 5 is ≥90%. The conductive layer 5 is an antistatic coating. This high light transmittance allows the protective film to provide antistatic protection without obstructing the view of the protected object, making it particularly suitable for occasions requiring transparent protection. At the same time, the conductive layer 5 uses an antistatic coating. This coating material not only has good conductivity, which can quickly conduct away the generated static electricity, but also has certain wear resistance and chemical resistance, which can extend the service life of the protective film. This combination allows the protective film to provide efficient antistatic protection while maintaining good durability and practicality.

[0029] See Figure 1 , Figure 2 , Figure 3 On the other side of the base layer 2, an adhesive layer 3 is coated. The adhesive layer 3 is a low-tack acrylic adhesive layer with a thickness of 3-5μm. The adhesive layer 3 allows the protective film to be easily pasted onto the protected object, providing good adhesion and firmness. At the same time, the adhesive layer 3 is a low-tack acrylic adhesive layer with a thickness of 3-5μm, which makes it easier to apply and remove the protective film without leaving adhesive residue or damaging the protected object. This ensures both the ease of use of the protective film and the surface integrity of the protected object.

[0030] See Figure 1 , Figure 2 , Figure 3 A release film is attached to the surface of the adhesive layer 3. The release film effectively protects the adhesive layer 3 from contamination or adhesion during storage and transportation, keeping the adhesive layer clean and sticky. At the same time, the use of the release film makes the protective film more convenient and quick to use. Simply peel off the release film to perform the pasting operation, which improves the convenience of storage and transportation of the protective film and enhances its usage efficiency.

[0031] Example 2:

[0032] See Figure 1 , Figure 2 , Figure 3 The antistatic protective film has several serrated grooves 6 formed at its edges, and these grooves 6 are arranged linearly at equal intervals. The serrated grooves 6 increase the flexibility of the edges. The regular arrangement of the serrated grooves 6 at equal intervals is not only aesthetically pleasing, but also allows the protective film to effectively guide air out during the bonding process, avoiding the generation of air bubbles and improving bonding efficiency and effect. This not only improves the bonding performance of the protective film, but also enhances its aesthetics and practicality.

[0033] The implementation principle of this embodiment is as follows: The protective film uses the base layer 2 as a supporting structure to provide the necessary strength and stability. A surface layer 1 is applied to the surface of the base layer 2. The surface layer 1 is formed into a protective surface 4 with a conical array surface by stamping, which increases the surface roughness. The physical structure design reduces the triboelectric effect, thereby reducing the dependence on traditional chemical antistatic agents. A conductive layer 5 is coated on the protective surface 4. The conductive layer 5 has good conductivity and can quickly conduct away the generated static electricity to prevent static electricity accumulation. At the same time, an adhesive layer 3 is coated on the other side of the base layer 2. The adhesive layer 3 is a low-tack acrylic adhesive layer, which facilitates the pasting and removal of the protective film. In order to protect the adhesive layer 3 from contamination or adhesion during storage and transportation, a release film is also provided on its surface. In addition, several equally spaced linearly arranged sawtooth grooves 6 are formed at the edge of the protective film. When the protective film is being pasted, the formed guide grooves can effectively guide the air out, improving the pasting efficiency and effect of the protective film.
