Description

Technical Field

[0001] This utility model belongs to the field of protective film technology, specifically relating to a high-temperature resistant pressure-sensitive adhesive protective film. Background Technology

[0002] High-temperature resistant pressure-sensitive adhesive protective films typically consist of a multi-layer structure, including a substrate, a pressure-sensitive adhesive layer, and other possible auxiliary layers (such as release film, buffer layer, etc.). Among these, the pressure-sensitive adhesive layer is the key component, as it imparts adhesion and protective properties to the protective film at high temperatures.

[0003] Application number "CN201921908267.5" describes "a high-temperature resistant pressure-sensitive adhesive protective film, comprising a substrate layer, a pressure-sensitive adhesive layer disposed on the lower surface of the substrate layer, an antistatic layer disposed on the upper surface of the substrate layer, a waterproof layer disposed on the upper surface of the antistatic layer, a high-temperature resistant layer disposed on the upper surface of the waterproof layer, and a wear-resistant layer disposed on the upper surface of the high-temperature resistant layer. The substrate layer, antistatic layer, waterproof layer, high-temperature resistant layer, and wear-resistant layer are bonded together by a hot-pressing process, and the pressure-sensitive adhesive layer is uniformly coated on the lower surface of the substrate layer."

[0004] The aforementioned patent, through the coordinated use of an antistatic layer, a waterproof layer, a high-temperature resistant layer, and a wear-resistant layer, enables the protective film to possess excellent high-temperature resistance, as well as antistatic, waterproof, and wear-resistant properties. It can protect the object being applied from contamination during high-temperature processing and is suitable for protecting various electronic and electrical products with temperature resistance requirements. However, if the outer protective layer of the aforementioned patent is damaged, the entire protective film needs to be removed and re-attached. This not only increases the overall cost of using the protective film but also increases the labor intensity required for manual removal of some firmly adhered protective films, further reducing the efficiency of workers in cleaning up damaged protective films. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant pressure-sensitive adhesive protective film, which aims to solve the problems of low overall cleaning efficiency of the protective film and inconvenience in replacing the outer protective layer of the protective film in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-temperature resistant pressure-sensitive adhesive protective film, comprising:

[0008] grassroots level;

[0009] A reinforcing layer is fixed to the lower surface of the base layer;

[0010] A pressure-sensitive adhesive layer is fixed to the lower surface of the reinforcing layer, which is used to fix the protective film to the object to be applied;

[0011] A disassembly mechanism is provided on the reinforcing layer to facilitate the disassembly and replacement of the outer protective layer;

[0012] A protective mechanism is provided on the reinforcing layer and is used in conjunction with the disassembly mechanism.

[0013] In a preferred embodiment of the present invention, the disassembly mechanism includes a first Velcro strap, a second Velcro strap is fixedly disposed on the upper surface of the first Velcro strap, and a connecting layer is fixedly disposed on the upper surface of the second Velcro strap.

[0015] As a preferred embodiment of this utility model, the pressure-sensitive adhesive layer is made of acrylic ester material, which can maintain stable adhesion performance in high temperature and high humidity environments and leaves no residue after peeling.

[0016] As a preferred embodiment of this utility model, the reinforcing layer is made of Teflon material, which is not easily damaged at high temperatures, thereby protecting the performance of the pressure-sensitive adhesive layer.

[0017] As a preferred embodiment of this utility model, the base layer is made of PET material, which improves the overall electrostatic adsorption and wear and scratch resistance of the base layer.

[0018] As a preferred embodiment of this utility model, the outer surface of the first hook and loop fastener is made of fine and soft fibers, and the inner surface of the second hook and loop fastener is made of harder, hooked bristles.

[0031] Example

[0032] Please see Figure 1-5 The present invention provides the following technical solution:

[0033] A high-temperature resistant pressure-sensitive adhesive protective film comprises a base layer 3, a reinforcing layer 2, a pressure-sensitive adhesive layer 1, a disassembly mechanism, and a protection mechanism, as detailed below:

[0034] Please see Figure 1 The reinforcing layer 2 is fixed to the lower surface of the base layer 3;

[0035] Please see Figure 2Pressure-sensitive adhesive layer 1 is fixed to the lower surface of reinforcing layer 2, which is used to fix the protective film to the object to be applied;

[0036] Please see Figure 3 The disassembly mechanism is located on the reinforcing layer 2, which facilitates the disassembly and replacement of the outer protective layer. Specifically, the disassembly mechanism includes a first hook and loop fastener 4, which is fixed to the upper surface of the base layer 3. A second hook and loop fastener 5 is fixed to the upper surface of the first hook and loop fastener 4, and a connecting layer 6 is fixed to the upper surface of the second hook and loop fastener 5.

[0037] Please see Figure 4 The protective mechanism is located on the reinforcing layer 2 and works in conjunction with the disassembly mechanism. Specifically, the protective mechanism includes an outer protective layer body 7, which is fixed to the upper surface of the connecting layer 6. A high-temperature resistant layer 8 is fixedly provided on the upper surface of the outer protective layer body 7, a waterproof layer 9 is fixedly provided on the upper surface of the high-temperature resistant layer 8, and a wear-resistant layer 10 is fixedly provided on the upper surface of the waterproof layer 9.

[0038] Please see Figure 5 The pressure-sensitive adhesive layer 1 is made of acrylic ester, which can maintain stable adhesion performance in high temperature and high humidity environments and leaves no residue after peeling.

[0039] Please see Figure 3 The reinforcing layer 2 is made of Teflon, which is not easily damaged at high temperatures, thus protecting the performance of the pressure-sensitive adhesive layer 1.

[0040] In this embodiment: by fixing the reinforcing layer 2 to the lower surface of the base layer 3, the reinforcing layer 2 is made of Teflon material, which is not easily damaged at high temperatures, thereby protecting the performance of the pressure-sensitive adhesive layer 1 and improving the overall adhesion effect of the protective film.

[0041] Please see Figure 5 The base layer 3 is made of PET material, which improves the overall electrostatic adsorption and wear and scratch resistance of the base layer 3.

[0042] Please see Figure 3 The outer surface of the first Velcro 4 is made of fine and soft fibrous round fibers, while the inner surface of the second Velcro 5 is made of harder hooked fibers.

[0043] In this embodiment: the first hook and loop fastener 4 is fixed to the upper surface of the base layer 3, the upper surface of the first hook and loop fastener 4 is fixed with a second hook and loop fastener 5, the upper surface of the second hook and loop fastener 5 is fixed with a connecting layer 6, the outer surface of the first hook and loop fastener 4 is a small and soft fiber loop, and the inner surface of the second hook and loop fastener 5 is a harder hooked loop, which makes it easy to remove all layers except the outer surface of the outer protective layer body 7 from the base layer 3. If the outer protective layer is damaged, it can be easily removed and replaced with a new outer protective layer. It is not necessary to remove the entire protective film. The outer protective layer can be replaced simply by peeling it off from under the protective film, which reduces the cost of use and the intensity of manual cleaning.

[0044] The working principle and usage process of this utility model are as follows: When the protective layer on the outer surface of the outer protective layer body 7 is broken, the small and soft fibrous loops on the outer surface of the first Velcro 4 and the harder hooked bristles on the inner surface of the second Velcro 5 can work together to easily remove all layers other than the outer surface of the outer protective layer body 7 from the base layer 3. This eliminates the need to remove the entire protective film and allows for the replacement of a new outer protective layer, effectively reducing usage costs and the intensity of manual cleaning.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
