Description

Technical Field

[0001] The utility model relates to the technical field of films, in particular to an anti-wear and anti-static film. Background Art

[0002] With the rapid development of the electronics industry, the integration of electronic circuit boards is getting higher and higher. The high density of electronic components on the motherboard, the compact wiring and even the widespread use of surface mount components are all prone to static damage to the circuit board. The use of anti-static film to package products can prevent static damage to the integrated circuit. Most of the existing anti-static films are sprayed with anti-static agents on plastic films to achieve the purpose of anti-static. However, when this anti-static film is used, the anti-static agent is easily worn away, which reduces the anti-static ability of the film. Therefore, a wear-resistant anti-static film is needed. Utility Model Content

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide an anti-wear antistatic film, including a base fabric layer, a metal shielding layer fixed on the base fabric layer, a wear-resistant component fixed on the metal shielding layer, and an antistatic component fixed on the wear-resistant component; the adjacent base fabric layers, metal shielding layers, and wear-resistant components are connected by colloid. The base fabric layer is the base of the anti-wear antistatic film and is made of glass fiber; the wear-resistant component contacts with the articles coated by the film to reduce the wear of the antistatic layer and enhance the wear resistance and service life of the film; there is a ">"-shaped partition between the adjacent base fabric layers, metal shielding layers, wear-resistant components, and antistatic components, and glue is injected between the partitions. The colloid can enhance the overall ductility of the film and is not easy to break when stretched. At the same time, due to the different ductility of various materials, when the film is bent, the colloid also provides extension space for each layer to prevent the layers from being dislocated due to different extension lengths when bent.

[0005] Specifically, the wear-resistant component includes a rubber layer fixed on the metal shielding layer, a wear-resistant head fixed on the rubber layer, a glue injection groove fixed on the rubber layer, and an adhesive fixed on the glue injection groove. The rubber layer is made of silicone rubber and has a good insulating effect. The wear-resistant head is in contact with the coated object. The wear-resistant head is in the shape of a boss, and a hemispherical protrusion is provided on the top of the boss. The wear-resistant head is narrow at the top and wide at the bottom, which can enhance the fracture resistance of the bottom of the wear-resistant head and prevent the bottom of the wear-resistant head from breaking when the film is bent; the glue injection groove is provided on the side of the rubber layer away from the wear-resistant head, and is in a "V" shape. Compared with the linear glue injection groove, more adhesive can be injected to increase the contact area between the adhesive and the lower layer, so that the bonding effect is better.

[0006] Specifically, the antistatic component includes an antistatic film layer fixedly arranged on the rubber layer.

[0007] Specifically, the base fabric layer is a mesh structure formed by a plurality of interlaced glass fibers, which have the advantages of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength.

[0008] Specifically, the metal shielding layer is made of soft aluminum foil.

[0009] Specifically, the antistatic film layer is made of inorganic nano polyurethane, which has excellent insulation properties.

[0010] Specifically, the wear-resistant head penetrates the antistatic film layer and directly contacts the coated object, thereby reducing the friction between the antistatic film layer and the object and reducing the wear of the antistatic film layer.

[0011] The beneficial effects of the utility model are:

[0012] (1) The structure is simple. It adopts a multi-layer composite structure. The base fabric layer is made of glass fiber, which ensures that the film has good wear resistance and insulation properties. The antistatic layer made of inorganic nano polyurethane gives the film good antistatic properties.

[0013] (2) There are “>”-shaped partitions between adjacent base fabric layers, metal shielding layers, wear-resistant components, and anti-static components. Glue is injected between the partitions. The colloid can enhance the overall ductility of the film and prevent it from breaking when stretched. At the same time, due to the different ductility of various materials, when the film is bent, the colloid also provides extension space for each layer to prevent the layers from being displaced due to different extension lengths when bent.

[0014] (3) The wear-resistant head is in the shape of a boss, and a hemispherical protrusion is provided on the top of the boss. The wear-resistant head is narrow at the top and wide at the bottom, which can enhance the anti-fracture performance of the bottom of the wear-resistant head and prevent the bottom of the wear-resistant head from breaking when the film is bent.

[0015] (4) The wear-resistant head penetrates the antistatic film layer and directly contacts the coated object, thereby reducing the friction between the antistatic film layer and the object and reducing the wear of the antistatic film layer.

[0016] (5) The glue injection groove is arranged on the side of the rubber layer away from the wear-resistant head and is in a "V" shape. Compared with the straight glue injection groove, more adhesive can be injected, increasing the contact area between the adhesive and the lower layer, so that the bonding effect is better.

[0033] Specifically, the metal shielding layer is made of soft aluminum foil.

[0034] Specifically, the antistatic film layer is made of inorganic nano polyurethane.

[0035] Specifically, the wear-resistant head penetrates the antistatic film layer.

[0036] When in use, the wear-resistant antistatic film is coated on the items that need to be antistatic. Since the wear-resistant head penetrates the antistatic film layer, the wear-resistant head will contact the items, reducing the friction between the antistatic film layer and the items, reducing the wear of the antistatic film layer, and enhancing the wear resistance of the film. The wear-resistant head is in the shape of a boss, and a hemispherical protrusion is provided on the top of the boss. The wear-resistant head is narrow at the top and wide at the bottom, which can enhance the anti-fracture performance of the bottom of the wear-resistant head, and prevent the bottom of the wear-resistant head from breaking when the film is bent.

Glue is injected between the partitions, which enhances the overall ductility of the film and is not easy to break when stretched. In addition, due to the different ductility of various materials, when the film is bent, the colloid also provides extension space for each layer, preventing each layer from being dislocated due to different extension lengths when bending. A "V"-shaped glue injection groove is provided on the side of the rubber layer away from the wear-resistant head. Compared with the straight glue injection groove, more adhesive can be injected to increase the contact area between the adhesive and the lower layer, so that the bonding effect is better.
