Description

Technical Field

[0001] This utility model relates to a waterproof release film, belonging to the field of release film technology. Background Technology

[0002] Currently, release films are widely used in adhesive products, building waterproofing materials, electronic products and other fields. Their main function is to protect adhesive surfaces during production, transportation or use, and prevent contamination, damage or premature bonding. When traditional release films are exposed to humid environments or come into direct contact with water, they are prone to water absorption, which can lead to a decline in film performance, difficulty in peeling, changes in adhesion, or even film breakage, thereby affecting the production efficiency and final use effect of the product. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a waterproof release film that can maintain good peeling effect and stable adhesion in humid environments.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a waterproof release film, comprising:

[0005] A flexible base film layer, wherein an elastic sealing ring is provided circumferentially in the flexible base film layer;

[0006] Release support layer, wherein the release support layer is disposed above the flexible base film layer, and the release support layer is provided with a plurality of uniformly distributed air-permeable micropores;

[0007] A waterproof protective layer is disposed above the release support layer, and an arc-shaped flow guide groove is provided on the outer surface of the waterproof protective layer, the arc-shaped flow guide groove extending along the length direction of the waterproof protective layer;

[0008] The flexible base film layer, the release support layer, and the waterproof protective layer are overlapped and bonded together from bottom to top.

[0009] Furthermore, the flexible base film layer is provided with an interwoven fiber framework.

[0010] Furthermore, the waterproof protective layer is provided with fluorescent core blocks, which are uniformly arranged along the length and width directions of the waterproof protective layer.

[0011] Furthermore, the release support layer is also provided with an antistatic mesh, which is compositely connected with the waterproof protective layer.

[0012] Furthermore, the bottom surface of the flexible base film layer is provided with an anti-slip groove, which is circular.

[0013] Furthermore, the depth of the anti-slip groove is one-third of the thickness of the flexible base film layer.

[0014] Furthermore, the elastic sealing ring is made of silicone, and the surface of the elastic sealing ring is also coated with a waterproof coating.

[0015] Furthermore, the inner side of the bottom of the arc-shaped flow channel is provided with a nano-hydrophobic coating.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. In this utility model, the elastic sealing ring of the flexible base film layer is made of silicone and coated with a waterproof coating, which can achieve circumferential sealing and prevent moisture penetration.

[0018] The release support layer combines breathable micropores with an antistatic mesh to expel moisture and prevent water vapor accumulation while eliminating static interference, ensuring contact between the release film and the adhesive material.

[0019] The arc-shaped drainage channels and nano-hydrophobic coating of the waterproof protective layer can effectively drain excess water and reduce the impact of residual water film on adhesion.

[0020] 2. In this utility model, the interwoven fiber frame can effectively enhance the tear resistance and deformation recovery ability of the flexible base film layer, and improve the performance of the product. Attached Figure Description

[0025] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] like Figure 1-4 As shown, a waterproof release film includes:

[0027] Flexible base film layer 1, with an elastic sealing ring 11 circumferentially provided in the flexible base film layer 1;

[0028] Release support layer 2 is disposed above flexible base film layer 1, and multiple uniformly distributed air-permeable micropores are provided on release support layer 2.

[0029] Waterproof protective layer 3 is set above release support layer 2. The outer surface of waterproof protective layer 3 is provided with arc-shaped guide groove 31, which extends along the length of waterproof protective layer 3.

[0030] The flexible base film layer 1, the release support layer 2, and the waterproof protective layer 3 are overlapped and bonded together from bottom to top.

[0031] Specifically, the flexible base film layer 1 is provided with an interwoven fiber framework. In this embodiment, the interwoven fiber framework can improve the tensile strength of the release film.

[0032] Specifically, such as Figure 3 As shown, the waterproof protective layer 3 is provided with fluorescent core blocks 32. The fluorescent core blocks 32 are evenly arranged along the length and width of the waterproof protective layer 3. In this embodiment, the fluorescent core blocks 32 refer to the release film that can be conveniently used by operators in dim conditions.

[0033] Specifically, such as Figure 1 As shown, the release support layer 2 is also provided with an antistatic mesh 21, which is compositely connected with the waterproof protective layer 3.

[0034] Specifically, such as Figure 1-2 As shown, the bottom surface of the flexible base film layer 1 is provided with an anti-slip groove 12, which is circular.

[0035] Specifically, such as Figure 1-2 As shown, the depth of the anti-slip groove 12 is one-third of the thickness of the flexible base film layer 1.

[0036] Specifically, the elastic sealing ring 11 is made of silicone, and the surface of the elastic sealing ring 11 is also coated with a waterproof coating.

[0037] The silicone elastic sealing ring has good elasticity and can adapt to different temperatures and environmental conditions. The waterproof coating on the surface further enhances the waterproof performance of the sealing ring.

[0038] Specifically, the inner side of the bottom of the arc-shaped guide channel 31 is provided with a nano-hydrophobic coating. The nano-hydrophobic coating can effectively guide the liquid to drain along the guide channel, reducing the accumulation of water stains and dirt.
