Description

Technical Field

[0001] This utility model relates to the field of release film technology, specifically to an easily peelable striped release film. Background Technology

[0002] Release film refers to a film with a distinct surface that, under limited conditions, exhibits no adhesion or only slight adhesion when in contact with specific materials. By treating its surface differently, it can exert extremely light and stable release force on various organic pressure-sensitive adhesives, thus making it widely used in the processing of various products. However, existing release films have poor release effects, strong adhesion, are difficult to peel off, and are not easy to tear and replace after application. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an easily peelable striped release film.

[0004] The technical solution of this utility model is as follows:

[0005] An easily peelable striped release film includes a substrate, the upper and lower surfaces of which are coated with a first protective coating and a second protective coating, respectively. The top of the first protective coating is provided with an anti-aging layer, and the bottom of the second protective coating is provided with a release layer. The lower surface of the release layer is provided with a plurality of rows of inwardly recessed striped grooves. One side of the substrate is integrally formed with an outwardly extending tear stripe.

[0006] Furthermore, the substrate is made of polyester or polyimide polymer material.

[0007] Furthermore, both the first and second protective coatings are flame-retardant coatings.

[0008] Furthermore, the first and second protective coatings are applied using nano-sized aluminum hydroxide flame retardant.

[0009] Furthermore, the nano-sized aluminum hydroxide flame retardant contains a conductive polymer resin.

[0010] Furthermore, the anti-aging layer is coated with polymethacrylate.

[0011] Furthermore, the release layer is a copperplate paper coated with silicone oil.

[0012] Furthermore, the tear strip is provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The substrate of this invention is made of polyester or polyimide polymer material, which has good mechanical strength and thermal stability. A first protective coating and a second protective coating are respectively coated on the upper and lower surfaces of the substrate. Both the first and second protective coatings are coated with nano-grade aluminum hydroxide flame retardant. Nano-grade aluminum hydroxide can prevent the release film from igniting due to excessive temperature, and can also prevent smoke, dripping, and the production of toxic gases, making it environmentally friendly and durable. Furthermore, the conductive polymer resin contained in the nano-grade aluminum hydroxide flame retardant can effectively reduce static electricity generation and prevent accidents. The top of the first protective coating has an anti-aging layer formed by coating with polymethyl methacrylate, which effectively enhances the aging resistance of the release film. The bottom of the second protective coating has a release layer with several rows of inwardly recessed grooves on its lower surface. The groove design effectively reduces the contact area between the release film and the product, thereby effectively reducing the release force of the release film for easy peeling. In addition, a tear strip is integrally formed on one side of the substrate, allowing for convenient and quick peeling of the release film, which is beneficial for users. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0025] Example

[0026] Please see Figure 1 , Figure 2 This embodiment provides an easily peelable striped release film, comprising a substrate 1, a first protective coating 2, a second protective coating 3, an anti-aging layer 4, and a release layer 5, wherein:

[0027] The substrate 1 is made of polyester or polyimide polymer material, which has good mechanical strength and thermal stability.

[0028] The upper and lower surfaces of the substrate 1 are coated with a first protective coating 2 and a second protective coating 3, respectively. The first protective coating 2 and the second protective coating 3 are flame-retardant coatings, which are coated with nano-sized aluminum hydroxide flame retardant containing conductive polymer resin. Nano-sized aluminum hydroxide can prevent the release film from catching fire due to excessive temperature, and can also prevent smoke, dripping, and toxic gas production. It is environmentally friendly and durable. In addition, the conductive polymer resin can effectively reduce static electricity and prevent accidents.

[0029] The top of the first protective coating 2 is provided with an anti-aging layer 4 formed by coating with polymethyl methacrylate, which effectively enhances the aging resistance of the release film.

[0030] The bottom of the second protective coating 3 is provided with a release layer 5, which is a copper plate paper coated with silicone oil, which is convenient for protecting the release layer 5 and for facilitating the storage and use of the release film.

[0031] The lower surface of the release layer 5 is provided with several rows of inwardly recessed stripe grooves 51. The design of the stripe grooves 51 can effectively reduce the contact area between the release film and the product, thereby effectively reducing the release force of the release film and facilitating peeling.

[0032] One side of the substrate 1 has an integrally formed tear strip 11 extending outwards, which allows the release film to be easily and quickly peeled off, which is beneficial to the user.

[0033] The tear strip 11 has anti-slip texture 111, which increases the friction of the outer surface of the tear strip 11 to facilitate the peeling of the release film.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
