Description

Technical Field

[0001] The utility model relates to the technical field of release paper processing, in particular to an easy-preservation antibacterial release paper suitable for high-temperature disinfection. Background Technique

[0002] Release paper is also called isolation paper. At present, release paper is widely used in the fields of food, electronics, chemical industry, etc. The matte release paper used in the food field lacks antibacterial function, so many foods are prone to spoilage and deterioration without the protection of special chemical additives, causing great losses.

[0003] For example, the existing patent (publication number: CN216514881U) discloses an easy-preservation antibacterial release paper, which coats an organic antibacterial agent vanillin on the surface of the second release agent layer to obtain an antibacterial layer. The antibacterial release paper can be applied to the fields of medicine, food packaging, etc. In the medical field, it can avoid the denaturation of the release paper caused by the ultraviolet lamp sterilization method during use, and protect patients from the harm of germs.

[0004] However, the above-designed easy-preservation antibacterial release paper still has some disadvantages in actual use: the antibacterial layer can only ensure that the release paper is prevented from deforming under the action of an ultraviolet lamp, and it cannot meet the need for high-temperature disinfection of some pharmaceutical products with release paper packaging. The release paper is prone to deformation during the high-temperature disinfection process, which will lead to a decrease in the adhesion between it and the packaged object.

[0005] Therefore, we designed an easy-preservation antibacterial release paper suitable for high-temperature disinfection to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide an easy-preservation antibacterial release paper suitable for high-temperature disinfection to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, an easy-preservation antibacterial release paper suitable for high-temperature disinfection provided by the utility model includes a base paper, and nano-silver adhesion layers are integrally formed on both the upper and lower bottom surfaces of the base paper. A fixing component is further provided outside the base paper, including a tear ring arranged outside the base paper. A tear layer is filled between the tear ring and the base paper, and a tear line is arranged on the side of the tear layer close to the base paper. The base paper is polytetrafluoroethylene paper.

[0008] Furthermore, a water retention layer is arranged on the top of the base paper. The water retention layer is adhered to the nano-silver adhesion layer on the top of the base paper. The area of the water retention layer is adapted to the base paper. The water content of the water retention layer is 5%, and the relative humidity is 50%.

[0009] Further, a first coating layer is adhesively bonded to the top of the base paper. Under the coating of the coating machine, the coating amount of the first coating layer is 14 grams per square meter.

[0010] Further, an antibacterial matte layer is adhesively bonded to the top of the first coating layer. The antibacterial matte layer matches the base paper. Titanium dioxide, an inorganic antibacterial agent, is applied to the surface of the antibacterial matte layer, which can generate free radicals with strong oxidizing properties under light conditions.

[0011] Further, a silane layer is provided at the bottom of the base paper, and the silane layer is adhesively bonded to the nano - silver adhesion layer at the bottom of the base paper.

[0012] Further, a second coating layer corresponding to the first coating layer is adhesively bonded to the bottom of the silane layer. A moisture - proof layer is adhesively bonded to the bottom of the second coating layer, and the relative humidity of the moisture - proof layer is 30%.

[0013] Further, openings are provided at both ends of the unsealing ring. Symmetrically arranged tear - easy grooves are provided on one side of the base paper near the two openings, and the shape of the tear - easy grooves is an inverted triangle.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The moisture in the water - retaining layer on the top of the base paper will evaporate accordingly to keep the moisture in the base paper and prevent it from deforming. At the same time, the unsealing ring on the outside of the base paper and the unsealing layer therebetween will always maintain the shaping of the base paper, ensuring that the size of the base paper does not change. The unsealing ring and the unsealing layer can ensure that the release paper will not be damaged due to thermal expansion, contraction or deformation in a high - temperature environment, thus maintaining its original physical structure and integrity.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: an easy-to-preserve antibacterial release paper suitable for high-temperature disinfection, including a base paper 1, and nano-silver adhesion layers are integrally formed on both the upper and lower bottom surfaces of the base paper 1. A fixing component is further provided outside the base paper 1, including a tear-off ring 3 provided outside the base paper 1. A tear-off layer 10 is filled between the tear-off ring 3 and the base paper 1. A tear line is provided on the side of the tear-off layer 10 close to the base paper 1. The base paper 1 is a polytetrafluoroethylene paper.

[0022] During specific implementation, after high-temperature sterilization, the base paper 1 pulls the opening 2, so that the tear-off layer 10 between the tear-off ring 3 and the base paper 1 is completely separated.

[0023] It should be noted that the polytetrafluoroethylene paper not only has excellent thermal stability and can withstand high-temperature environments, but also has good chemical resistance.

[0024] Refer to Figures 1-4 As shown, a water-retaining layer 4 is provided on the top of the base paper 1. The water-retaining layer 4 is bonded to the nano-silver adhesion layer on the top of the base paper 1. The area of the water-retaining layer 4 is adapted to that of the base paper 1.

[0025] A first coating layer 5 is bonded to the top of the base paper 1.

[0026] An antibacterial matte layer 6 is bonded to the top of the first coating layer 5. The antibacterial matte layer 6 matches the base paper 1, and an inorganic antibacterial agent titanium dioxide is coated on the surface of the antibacterial matte layer 6.

[0027] A silane layer 9 is provided at the bottom of the base paper 1. The silane layer 9 is bonded to the nano-silver adhesion layer at the bottom of the base paper 1.

[0028] A second coating layer 8 corresponding to the first coating layer 5 is bonded to the bottom of the silane layer 9. A moisture-proof layer 7 is bonded to the bottom of the second coating layer 8.

[0029] It should be noted that the various different coating layers and materials used can all withstand the temperature during high-temperature disinfection of the base paper 1, and the structure remains stable without damaging the structure of the base paper 1.

[0030] Refer to Figures 1-4, there are tear openings 2 provided at both ends of the unsealing ring 3, and symmetrical tear grooves 11 are provided on one side of the base paper 1 close to the two tear openings 2. The shape of the tear groove 11 is an inverted triangle.

[0031] During specific implementation, when tearing, it can be torn from the tear groove 11 provided on the base paper 1.

[0032] Working principle: When high-temperature sterilization is required, the moisture in the water-retaining layer 4 at the top of the base paper 1 will evaporate accordingly to maintain the moisture in the base paper 1 and prevent it from deforming. At the same time, the unsealing ring 3 provided outside the base paper 1 and the unsealing layer 10 therebetween will always maintain the shaping of the base paper 1 to ensure that the size of the base paper 1 does not change;

[0033] Furthermore, after the high-temperature sterilization is completed, the base paper 1 pulls the tear opening 2, thereby enabling the unsealing layer 10 between the unsealing ring 3 and the base paper 1 to be completely separated. After separation, the base paper 1 is attached to the antibacterial matte layer 6 and the moisture-proof layer 7 again to complete long-term bacteria isolation.
