Description

Technical Field

[0001] This utility model is a lightweight textured PVC film, belonging to the field of PVC film. Background Technology

[0002] PVC film is a multifunctional plastic film made of polyvinyl chloride resin and other modifiers through calendering or blow molding processes. It is widely used in building materials, packaging, medicine, electronics and other fields, and has properties such as corrosion resistance, insulation and flexibility.

[0003] Existing textured PVC films have the following three molding methods for their rough surfaces:

[0004] It is pressed directly by machine;

[0005] The melt is cast onto release paper and formed into a smooth base film by cooling rollers. A rough surface is then formed by sandblasting or etching processes.

[0006] First, hot-melt particles are sprayed onto a glossy base film, and then the surface structure is fixed by secondary pressing.

[0007] Machine pressing can easily damage the membrane material, while surface spraying with particles results in a less robust structure. When subjected to abrasion, the particles can easily tear along with the membrane base layer. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight rough PVC film to solve the problems that the existing machine pressing method is prone to damage to the film material, and the surface spraying of particles is not very strong, and the particles are easy to tear along with the film base when it is scratched.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a lightweight textured PVC film, the structure of which includes a PVC base layer and a lightweight textured structure; the lightweight textured structure is connected to the top surface of the PVC base layer;

[0010] The lightweight rough surface structure includes a reinforced adhesive layer in contact with the PVC base layer and a surface layer connected to the top surface of the reinforced adhesive layer. The reinforced adhesive layer has several injection holes, and a reinforcing component extending into the PVC base layer is provided at the bottom of the injection holes. The bottom surface of the surface layer has a wrapping groove corresponding to the injection holes. The wrapping groove and the injection holes form a wrapping chamber, and an elastomer is provided in the wrapping chamber. The top surface of the surface layer is hot-pressed and applied to the elastomer to form several notches on its surface.

[0011] Furthermore, to enhance the connection effect, the reinforcing component includes two glue injection channels arranged in an alternating manner.

[0012] Furthermore, in order to improve the bonding strength of the elastomer, the encapsulation cavity is filled with an adhesive that extends into the injection channel, thereby forming a reinforced adhesive sleeve that encapsulates and fixes the elastomer.

[0013] Furthermore, to enhance the three-dimensional effect of the notch, the elastomer has a spherical or rugby ball-shaped structure.

[0014] Furthermore, for adhesive packaging, the PVC base layer includes a base body and an adhesive layer adhered to the bottom surface of the base body.

[0015] Furthermore, in order to improve ductility, the bottom surface of the adhesive layer is provided with a plurality of extended grooves, and an extended slit is cut at the center of the top of the extended groove.

[0016] Furthermore, the cross-section of the extended groove is either arc-shaped or conical.

[0017] The beneficial effects of this utility model are as follows: An elastomer is set in the interlayer of the PVC film, and the elastomer is wrapped and fixed by the encapsulation chamber and the reinforcing adhesive sleeve, which ensures the stability of the connection. While the reinforcing adhesive sleeve connects the elastomer, it also works with the glue injection channel to strengthen the connection of the PVC base layer. Under machine pressing, it effectively prevents the film material from being damaged. Finally, the surface layer forms a lightweight rough surface through the notch. The lightweight rough surface can maintain the structural firmness even when scratched. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0023] Please see Figure 1 , Figure 2This utility model provides a lightweight textured PVC film technical solution: its structure includes a PVC base layer 1 and a lightweight textured structure 2; the lightweight textured structure 2 is connected to the top surface of the PVC base layer 1;

[0024] The lightweight rough surface structure 2 includes a reinforced adhesive layer 21 connected to the PVC base layer 1 and a surface layer 22 connected to the top surface of the reinforced adhesive layer 21. The reinforced adhesive layer 21 is made of PUR adhesive and has the advantages of being environmentally friendly, having high adhesion performance, and strong impact resistance.

[0025] The reinforced adhesive layer 21 is provided with a plurality of glue injection holes 23. The bottom of the glue injection holes 23 is provided with a reinforcing component extending into the interlayer of the PVC base layer 1. The bottom surface of the surface layer 22 is provided with a wrapping groove 25 corresponding to the glue injection holes 23. The wrapping groove 25 and the glue injection holes 23 form a wrapping chamber. An elastomer 26 is provided in the wrapping chamber. The top surface of the surface layer 22 is hot-pressed and applied to the elastomer 26, so that a plurality of notches 27 are formed on its surface.

[0026] Among them, elastomer 26 is specifically TPU microparticles, which have the advantages of being lightweight, highly elastic, wear-resistant, and having high adhesion performance.

[0027] To enhance the connection effect, the reinforcing component includes two glue injection channels 24 arranged in an alternating manner.

[0028] To improve the connection strength of the elastomer 26, the encapsulation chamber is filled with adhesive that extends into the injection channel 24, thereby forming a reinforced adhesive sleeve that encapsulates and fixes the elastomer 26.

[0029] To enhance the three-dimensional effect of the notch 27, the elastic body 26 is a spherical or rugby ball-shaped structure. It is preferred to use a spherical elastic body 26 for ease of processing. However, this invention is not limited to this, and the elastic body 26 can also be a cylindrical, prism, or other structure.

[0030] For adhesive packaging, the PVC base layer 1 includes a base body 11 and an adhesive layer 12 bonded to the bottom surface of the base body 11.

[0031] Principle: An elastomer 26 is placed inside the PVC film interlayer. The elastomer 26 is wrapped and fixed by the encapsulation chamber and the reinforcing adhesive sleeve, which ensures the stability of the connection. While the reinforcing adhesive sleeve connects the elastomer 26, it also works with the glue injection channel 24 to strengthen the connection of the PVC base layer 1. Under machine pressing, the membrane material is effectively prevented from being damaged. Finally, the surface layer 22 forms a lightweight rough surface through the notch 27. This lightweight rough surface can maintain the structural firmness even when scratched. Example 2
