Description

Technical Field

[0001] The utility model belongs to the technical field of release films, and in particular relates to a self-stripping radiation-resistant release film. Background Art

[0002] After traditional hot melt adhesive, oil adhesive, and silicone gel are coated, a release film is needed to protect the colloid. The release film is generally made of plastic PE / PP / PET sheets coated with silicone oil. When using, you need to peel off the unadhered part by hand.

[0003] At present, the hard release film often irritates the skin, and the strong adhesion causes the colloids to stick to each other during the peeling process. If it is a medical product, it will cause secondary pollution during the release process. Utility Model Content

[0004] The utility model aims to provide a self-peeling radiation-resistant release film in order to solve the problem that the release film has strong adhesion force and colloids adhere to each other during the peeling process.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a self-peeling radiation-resistant release film, which includes a base layer, a moisturizing layer and a protective layer, and the moisturizing layer and the protective layer are respectively solidified on the upper surface and the lower surface of the base layer.

[0006] As a further description of the above technical solution:

[0007] The base layer is a napped cloth.

[0008] As a further description of the above technical solution:

[0009] The moisturizing layer is a hydrogel.

[0010] As a further description of the above technical solution:

[0011] The protective layer is a two-component silicone gel or a single-component UV silicone gel.

[0012] As a further description of the above technical solution:

[0013] The protective layer is cured on the lower surface of the base layer by ultraviolet rays.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] In the utility model, a release film is manufactured by curing the moisturizing layer and the protective layer on the base layer. The user does not need to peel off the release film manually. After opening the package, the user can directly use the pressure-sensitive adhesive to stick and fix the parts, thereby avoiding secondary contamination. The release film can withstand irradiation to achieve sterility, and the user experience is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , the utility model provides a technical solution: a self-peeling radiation-resistant release film, comprising a base layer 1, a moisturizing layer 2 and a protective layer 3, wherein the moisturizing layer 2 and the protective layer 3 are respectively solidified on the upper surface and the lower surface of the base layer 1;

[0021] The base layer 1 is a napped cloth;

[0022] The moisturizing layer 2 is a hydrogel, and the hydrogel liquid has the effects of self-lubrication and high resistance;

[0023] The protective layer 3 is a two-component silicone gel or a single-component UV silicone gel;

[0024] The protective layer 3 is cured on the lower surface of the base layer 1 by ultraviolet rays.

[0025] Working principle: First, prepare a high-quality self-water-based gel for the moisturizing layer 2. The hydrogel is prepared by mixing carrageenan and PVP in a weight ratio of 2:3 to prepare a hydrogel liquid with a water content of more than 90%, which has self-lubrication and high resistance. Secondly, apply an ultra-thin layer of hydrogel on the upper surface of the base layer 1, solidify it after three minutes, and finally apply a thin layer of two-component silicone gel or single-component UV silicone gel on the protective layer 3 on the back of the base layer 1, and then cure it with ultraviolet light. Cut it into the required size to obtain a new release film. When the release film is used, the hydrogel The coating surface is the contact surface of the pressure-sensitive adhesive, and the silicone gel surface is exposed for packaging. Since water molecules do not combine with the pressure-sensitive adhesive, there will be no adhesion, and the exposed silicone gel coating will contact the packaging material and adhere together. When the package is opened, the release film will automatically peel off the surface of the pressure-sensitive adhesive product, forming a release film that can protect the pressure-sensitive adhesive product and can be peeled off by itself and can be irradiated, avoiding secondary contamination, and can withstand irradiation to achieve sterility, effectively improving the user experience, and the materials used have high biocompatibility and can be used in the medical field.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
