Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to an acrylic waterproof protective film. Background Art

[0002] An acrylic waterproof protective film is a protective film made of acrylic material with waterproof performance. It has good characteristics, can effectively block the penetration of moisture, protect the covered object from water damage; maintain a clear visual effect without affecting the appearance display of the protected object; have strong wear resistance and can resist friction and scratching in daily use; can adapt to objects of different shapes and surfaces and fit closely; have a certain resistance to a variety of chemical substances. However, the existing PET double-layer acrylic protective film does not have the function of waterproofing, and cannot protect the items when encountering water during use, thus easily causing damage to the items.

[0003] Patent CN207241069U discloses a PET double-layer acrylic waterproof protective film. This solution solves the problem that the existing PET double-layer acrylic protective film does not have the waterproof function by setting a waterproof layer in the film layer. However, due to the film being exposed to sunlight for a long time, it is prone to aging and yellowing, so the waterproof performance of the film body will decrease. Therefore, the anti-ultraviolet performance of the waterproof protective film also needs to be improved synchronously to ensure the long-term use of the film body. Therefore, this application proposes an acrylic waterproof protective film with high anti-ultraviolet performance. Summary of the Invention

[0004] The purpose of the utility model is to address the problems in the background art and propose an acrylic waterproof protective film with high anti-ultraviolet performance.

[0005] The technical solution of the utility model: An acrylic waterproof protective film, the protective film includes a base material layer, and further includes an adhesive layer connected to one side of the base material layer. A release paper layer is provided on the side of the adhesive layer away from the base material layer, and an auxiliary waterproof layer is provided on the side of the base material layer away from the adhesive layer, and a waterproof layer is provided on one side of the auxiliary waterproof layer;

[0006] On the side wall of the base material layer close to the auxiliary waterproof layer, a plurality of groups of concave grooves are also arrayed;

[0007] The auxiliary waterproof layer includes an ethylene propylene diene monomer rubber layer bonded to the waterproof layer and a plurality of groups of filling bodies corresponding to the concave grooves.

[0008] Optionally, the inner side surface of the concave groove is a convex part, and cutting surfaces are symmetrically provided on both sides of the convex part.

[0009] Optionally, the included angle between the two cutting surfaces is 45°.

[0010] Optionally, the convex portion is a 1 / 8 circular arc surface.

[0011] Optionally, the filling body includes a concave surface portion that matches the arc surface of the convex portion and a fitting portion that fits with the two side cutting surfaces.

[0012] Optionally, the thickness of the base material layer is 0.01 - 0.03 mm.

[0013] Optionally, the thickness of the adhesive layer is 0.005 - 0.01 mm, and the thickness of the release paper layer is 0.005 - 0.01 mm.

[0014] Optionally, the waterproof layer is made of polyvinyl chloride with a thickness of 0.01 μm.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] The present utility model realizes the waterproof protection of the base material layer through the setting of the waterproof layer, and the setting of the ethylene propylene diene monomer layer can isolate a certain amount of sunlight irradiation. At the same time, the setting of the filling body and the opening of the concave grooves on the base material layer reduce the area or angle of direct ultraviolet irradiation, so that the light passing through the film body is refracted out, reducing the sun damage to the film-applied product;

[0017] The present utility model reduces the direct light source through the spaced concave grooves, enhances the ultraviolet resistance of the film body, extends the service life of the film body, and thus enhances the protection effect of the film body. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment

[0035] As Figures 1-4As shown in the figure, the present utility model provides an acrylic waterproof protective film. The protective film includes a substrate layer 1 with a thickness of 0.02 mm; it also includes an adhesive layer 2 connected to one side of the substrate layer 1, with a thickness of 0.008 mm; on the side of the adhesive layer 2 away from the substrate layer 1, there is a release paper layer 3 connected thereto, with a thickness of 0.01 mm; on the side of the substrate layer 1 away from the adhesive layer 2, there is an auxiliary waterproof layer 5, and on one side of the auxiliary waterproof layer 5, there is a waterproof layer 4 which is made of polyvinyl chloride with a thickness of 0.01 μm; through the setting of the waterproof layer 4, the waterproof effect of the film body is enhanced.

[0036] Further, as Figure 3 and Figure 4 shown in the figure, on the side wall of the substrate layer 1 close to the auxiliary waterproof layer 5, there are also multiple groups of concave grooves 10 arranged in an array. The inner side surface of the concave groove 10 is a convex part 11, and the convex part 11 is a 1 / 8 arc surface; on both sides of the convex part 11, there are symmetrically arranged cutting surfaces 12, and the included angle between the two groups of cutting surfaces 12 is 45°. When a light source passes through the waterproof layer 4 and then through the transparent auxiliary waterproof layer 5, the light source will irradiate on the convex part 11 and the cutting surfaces 12. Since the convex part 11 is an arc surface, the light source will be reflected at different angles to the cutting surfaces 12, and the cutting surfaces 12 will reflect the light source again and pass through the auxiliary waterproof layer 5 and the waterproof layer 4 to return, thus achieving the effect that ultraviolet rays cannot pass through or only a small amount can pass through the film body, thereby improving the anti-ultraviolet performance of the protective film, and thus improving the overall protection effect of the acrylic waterproof protective film.

[0037] Further, as Figure 5 shown in the figure, the auxiliary waterproof layer 5 includes an ethylene propylene diene monomer (EPDM) rubber layer 51 bonded to the waterproof layer 4 and multiple groups of filling bodies 52 corresponding to the concave grooves 10; the filling body 52 includes a concave part 521 matching the arc surface of the convex part 11 and a fitting part 522 fitting the two side cutting surfaces 12. Through the corresponding setting of the filling body 52 and the concave grooves 10, the concave grooves 10 are filled corresponding to the concave grooves 10 while ensuring their reflection performance, thereby ensuring the strength of the film body.

[0038] The above specific embodiments are merely several optional embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
