Description

Technical Field

[0001] The utility model relates to the technical field of release paper, in particular to a high-temperature resistant, anti-off and antibacterial release paper. Background Art

[0002] Release paper usually includes a base paper and a release agent. The release agent can be used to isolate sticky objects and is commonly used as a carrier for tapes or adhesive products.

[0003] The release agent has certain permeability. If there is no certain barrier on the base paper, the release agent will penetrate into the interior of the base paper, resulting in a problem of excessive consumption of the release agent. Therefore, a coating layer is usually provided on the base paper to block the release agent. The coating layer generally uses PE material, which can withstand a maximum temperature of 80°C to 90°C, has poor high-temperature resistance, is prone to deformation, and even falls off from the base paper, restricting the scope of use. In addition, ordinary release paper does not have antibacterial effect and needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-temperature resistant, anti-off and antibacterial release paper to improve the high-temperature resistance effect and increase the antibacterial property.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-temperature resistant, anti-off and antibacterial release paper, comprising: an antibacterial layer, a base paper layer, a high-temperature resistant isolation layer and a release layer. The antibacterial layer is arranged on the bottom surface of the base paper layer, the high-temperature resistant isolation layer is arranged on the top surface of the base paper layer, the release layer is arranged on the top surface of the high-temperature resistant isolation layer. Micropores are arranged at intervals on the high-temperature resistant isolation layer. The release layer uses an organosilicon release agent, and part of the organosilicon release agent flows through the micropores to the gaps of the base paper layer and forms fixed points after drying.

[0007] Among them, the high-temperature resistant isolation layer uses a high-temperature resistant plastic film.

[0008] Among them, the high-temperature resistant plastic film includes a PET film and a PI film.

[0009] Among them, the base paper layer uses fiberglass paper.

[0010] Among them, the antibacterial layer uses a nano silver coating.

[0011] Among them, the micropores are distributed in a rectangular array on the high-temperature resistant isolation layer.

[0012] Among them, the diameter of the micropores is 0.1 - 0.5 mm.

[0013] Advantages of the present utility model: A high-temperature resistant, anti-detachment and antibacterial release paper is specially designed with an antibacterial layer for surface antibacterial protection. The high-temperature resistant isolation layer uses a high-temperature resistant plastic film, which has good adaptability to high-temperature environments and can be applicable to high-temperature environments within 150°. The fixing points formed by the silicone release agent in the base paper layer strengthen the fixation of the high-temperature resistant isolation layer on the base paper layer, avoiding the problem of the high-temperature resistant plastic film peeling off from the base paper layer. Brief Description of the Drawings

[0014] Figure 1 is a structural schematic diagram of the present utility model;

[0015] Figure 2 is Figure 1 a partial enlarged view of part A in Detailed Embodiments

[0016] The following combines Figures 1 to 2 and further illustrates the technical solutions of the present utility model through specific embodiments.

[0017] As Figure 1 shown in the high-temperature resistant, anti-detachment and antibacterial release paper, including: an antibacterial layer 5, a base paper layer 1, a high-temperature resistant isolation layer 2 and a release layer 4. The antibacterial layer 5 is disposed on the bottom surface of the base paper layer 1. In this embodiment, the antibacterial layer uses a nano-silver coating, which has antibacterial and mildew-proof effects and is beneficial to improving the use safety of the release paper.

[0018] The high-temperature resistant isolation layer 2 is disposed on the top surface of the base paper layer 1. In this embodiment, the high-temperature resistant isolation layer 2 uses a high-temperature resistant plastic film, and the high-temperature resistant plastic film includes a PET film and a PI film, which can maintain stability in high-temperature environments below 150°C, improving the high-temperature resistant effect.

[0019] The release layer 4 is disposed on the top surface of the high-temperature resistant isolation layer 2. In this embodiment, the release layer 4 uses a silicone release agent, and the silicone release agent can withstand high temperatures within 200°C and is relatively stable in high-temperature environments.

[0020] Micropores 3 are disposed at intervals on the high-temperature resistant isolation layer 2. As Figure 2 shown, part of the silicone release agent flows through the micropores 3 to the gaps of the base paper layer 1 and forms fixing points 6 after drying, strengthening the fixation of the high-temperature resistant isolation layer 2 on the base paper layer 1, with stable structure and avoiding the problem of the high-temperature resistant plastic film 2 peeling off from the base paper layer 1.

[0021] In this embodiment, the diameter of the micropores 3 is 0.1 - 0.5 mm. The smaller the diameter of the micropores 3, the smaller the formed fixing points 6. Therefore, the silicone release agent consumed for the formation of the fixing points 6 is less, and the cost can be ignored. In addition, as Figure 1As shown, the micropores 3 are distributed in a rectangular array on the high-temperature resistant isolation layer 2, and fixed points 6 distributed in a rectangular array can be formed, further enhancing the stability of the high-temperature resistant isolation layer 2 on the base paper layer 1.

[0022] In order to form the fixed points 6, the base paper layer 1 needs to have certain gaps, such as Figure 2 As shown, in this embodiment, the base paper layer 1 is made of fiberglass paper, which is made of glass fibers and contains a large number of tiny gaps that can be filled with silicone release agent. After curing, the fixed points 6 are obtained, which is convenient for production.

[0023] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
