PET reticulated release film

Abstract

The utility model provides a PET (Polyethylene Terephthalate) reticulated release film, which belongs to the technical field of release films and comprises a reticulated release film body, the reticulated release film body comprises a polyethylene glycol terephthalate base material, a glass fiber layer is arranged on the upper surface of the polyethylene glycol terephthalate base material, the upper side of the glass fiber layer is an inclined surface, and the lower side of the glass fiber layer is an inclined surface. According to the release film, in the process of using the release film, due to the fact that the upper surface layer of the release film is the inclined plane, when the release film is horizontally placed, if the temperature is suddenly changed or water is sprayed on the reticulate pattern, the area coverage rate of the small water drops can be reduced under the influence of factors such as self-gravity and low friction of the small water drops, and the water drops are prevented from falling off. And therefore, a user can conveniently clean the inclined plane, the inclined plane is easy to machine and form, and the cost is low.

Description

Technical Field

[0001] The utility model mainly relates to the technical field of release films, in particular to a PET reticulated release film. Background Art

[0002] Release film refers to a film with distinguishable surface. The release film is non-sticky or slightly sticky when in contact with specific materials under limited conditions. Release film is also called peeling film, isolation film, separation film, adhesive barrier film, release film, film, plastic film, masking film, silicone oil film, silicone oil paper, anti-adhesive film, mold paper, slip film, Tianna paper and release paper, etc. PET release film is a material commonly used in thermal transfer. The base material is PET, which is coated with silicone oil, so it is also called silicone oil film. It can be divided into hot and cold tear and matte surface. After anti-static and anti-scratch treatment, the product has good adsorption and adhesion.

[0003] The mesh on the PET textured release film is first coated with silicon and then embossed. This kind of mesh is mostly diamond-shaped and includes many characteristics: First, it is scratch-resistant protection, with high scratch resistance, which can effectively protect the surface of objects from scratches and wear; second, it is anti-fingerprint. Due to its special mesh texture, the PET textured protective film can reduce the visibility of fingerprints on the surface and keep the surface of objects clean and beautiful; third, it increases anti-slip properties. The mesh texture can increase the friction of the surface of objects, provide additional anti-slip function, and make objects more stable and easy to hold; fourth, it increases visual effects. The mesh texture can add a unique visual effect to the surface of objects and enhance the appearance and texture of the product. However, during the use of the PET textured release film, when the temperature changes suddenly or when water is sprinkled on the diamond mesh, many small water droplets will be embedded in the small grooves formed by the mesh, which cannot be shaken off or simply wiped. It needs to be wiped with a water-absorbent and smooth cloth. In addition, since the release film is very long, it needs to be judged by the human eye, which is very inconvenient and easy to leave marks. Utility Model Content

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the present invention mainly provides a PET textured release film to solve the technical problems mentioned in the above background technology that the texture on the current PET textured release film is easily embedded with small water droplets, affecting the visual and aesthetics, and is difficult to clean.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A PET textured release film comprises a textured release film body, wherein the textured release film body comprises a polyethylene terephthalate substrate, a glass fiber layer is arranged on the upper surface of the polyethylene terephthalate substrate, and the upper side of the glass fiber layer is an inclined surface, and a line textured layer is arranged on the inclined surface of the glass fiber layer.

[0007] Furthermore, the line textured layer includes embossed linear grooves, and an arc-shaped protrusion is between every two adjacent linear grooves.

[0008] Furthermore, an antistatic layer is provided on the lower surface of the polyethylene terephthalate substrate.

[0009] Furthermore, a mixed silicone oil layer is provided on the lower surface of the antistatic layer.

[0010] Furthermore, the mixed silicone oil layer and the antistatic layer have the same thickness.

[0011] Furthermore, the thickness of the glass fiber layer is greater than the sum of the thicknesses of the mixed silicone oil layer and the antistatic layer.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model realizes that in the process of using the release film, since the upper surface layer of the release film is an inclined surface, when it is placed horizontally, if the temperature changes suddenly or water is spilled on the reticulation, the small water droplets can reduce the area coverage of the small water droplets under the influence of their own gravity and low friction factors, and will flow to the side with the lower inclined surface, which is convenient for users to clean. The utility model is easy to process and shape, and has low cost. The mixed silicone oil layer is prepared by mixing solvent-free silicone oil and solvent-based silicone oil, and has a low silicon content. When in use, the release film can be easily peeled off from the attached material, and has certain practical value.
