Description

Technical Field

[0001] This utility model relates to the field of explosion-proof film technology, and in particular to a roll-type explosion-proof film structure. Background Technology

[0002] Explosion-proof film, as an auxiliary safety material, is widely used in display products. It is typically adhered to the glass surface via OCA (Optical Adhesive Acrylic Acid). When the glass breaks, the adhesive properties of the film prevent shattering. Before application, the explosion-proof film is cut to the required shape, usually supplied in sheets or rolls. In actual application, due to the adhesive properties of the OCA at the edges, roll-packaged explosion-proof film easily attracts debris and other lint contaminants, leading to surface contamination after application, affecting display quality, and resulting in product defects. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a roll-type explosion-proof film structure.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A roll-type explosion-proof film structure includes: a substrate and an explosion-proof film disposed on the substrate. The substrate is rolled up, and multiple explosion-proof films are fixed on the substrate. The multiple explosion-proof films are distributed at equal intervals along the length direction of the substrate. A protective film for protecting the explosion-proof film is provided on the substrate, and the protective film covers the surface of the multiple explosion-proof films.

[0006] In one embodiment, the substrate is a light release film, and the side of the substrate that contacts the plurality of explosion-proof films has weak adhesion.

[0007] In one embodiment, the distance between two adjacent explosion-proof films on the substrate is 2 mm, and the distance between the upper and lower sides of the explosion-proof film and the upper and lower outer edges of the substrate is 4 mm.

[0008] In one embodiment, the protective film has a weak adhesive layer on one side, the side of the protective film facing the multiple explosion-proof films has a weak adhesive layer, and the size of the protective film is adapted to the size of the substrate.

[0009] In one embodiment, the protective film is made of PET material.

[0010] In one embodiment, the protective film has an adhesive on the side facing the substrate, the adhesive is wrapped around the inner circumference of the protective film, and the side of the adhesive away from the protective film is bonded and fixed to the substrate.

[0011] In one embodiment, the adhesive surrounds the outer side of the plurality of explosion-proof films, the inner side of the adhesive is a certain distance from the outer side of the explosion-proof film, and the distance between the inner side of the adhesive and the outer edge of the explosion-proof film adjacent to it is 2mm-3mm.

[0012] In one embodiment, the adhesive is more viscous to the side of the protective film that is adhered to than the adhesive is more viscous to the side of the substrate that is adhered to.

[0013] In one embodiment, the explosion-proof film includes a release film, a PET layer and an OCA adhesive layer arranged sequentially from top to bottom. The OCA adhesive layer is adhered to the substrate, and the protective film covers the surface of the release film.

[0014] In one embodiment, a self-cleaning dustproof layer is provided between the PET layer and the OCA adhesive layer.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. The roll-type explosion-proof film structure of this utility model covers the surface of the incoming explosion-proof film with a protective film, and the inner circumference of the protective film is provided with adhesive. The adhesive surrounds the outer edge of multiple explosion-proof films near the outer edge of the substrate, so as to protect the outer edge of the explosion-proof film from contamination.

[0017] 2. The roll-type explosion-proof film structure of this utility model enhances the anti-fouling ability of the explosion-proof film by setting a self-cleaning dustproof layer inside the explosion-proof film, so that the explosion-proof film can maintain the bright and clean effect of the display product for a long time when it is attached to the display product.

[0022] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0023] A roll-type explosion-proof membrane structure, as shown in the reference. Figure 1 It includes a substrate 10 and an explosion-proof film 20 disposed on the substrate 10. The substrate 10 is rolled up and multiple explosion-proof films 20 are fixed on the substrate 10. The multiple explosion-proof films 20 are distributed at equal distances along the length direction of the substrate 10 and are discharged by rolling.

[0024] The substrate 10 is provided with a protective film 30 for protecting multiple explosion-proof films 20. The protective film 30 covers the surface of the multiple explosion-proof films 20 to protect them and prevent debris and other lint contaminants from sticking to the edges of the explosion-proof films 20, which would cause sheet contamination after application. It should be noted that the protective film 30 is rolled up together with the substrate 10 so that the protective film 30 covers the surface of all the explosion-proof films 20 on the substrate 10 before being unloaded.

[0025] Furthermore, the substrate 10 is a light release film, and the side of the substrate 10 that contacts the multiple explosion-proof films 20 has weak adhesion so that the explosion-proof films 20 can be easily peeled off when the substrate 10 is removed.

[0026] Furthermore, the spacing between two adjacent explosion-proof films 20 on the substrate 10 is 2mm, and the upper and lower sides of the explosion-proof film 20 are 4mm away from the upper and lower outer edges of the substrate 10, respectively. The certain distance between adjacent explosion-proof films 20 prevents them from contacting each other and sticking together, and each explosion-proof film 20 is also a certain distance from the outer edge of the substrate 10 to prevent the outer edge of the explosion-proof film 20 from directly contacting the outside and easily attracting contaminants.

[0027] Furthermore, the protective film 30 is provided with a weak adhesive on one side, with the side of the protective film 30 facing the multiple explosion-proof films 20 having a weak adhesive, and the size of the protective film 30 is adapted to the size of the substrate 10. In this way, the protective film 30 with weak adhesive can fix the protective film 30 to the multiple explosion-proof films 20, while not damaging the explosion-proof films 20 when the protective film 30 is peeled off.

[0028] Furthermore, the protective film 30 is made of PET material.

[0029] Furthermore, to further prevent contaminants from adhering to the outer edge of the explosion-proof film 20, an adhesive 31 is provided on the side of the protective film 30 facing the substrate 10. The adhesive 31 is arranged in a U-shape and is adhered to the inner circumference of the protective film 30. The adhesive 31 is wrapped around the inner circumference of the protective film 30, and the side of the adhesive 31 away from the protective film 30 is bonded and fixed to the substrate 10. The adhesive 31 surrounds the outer edges of multiple explosion-proof films 20 near the outer edge of the substrate 10 to protect the outer edge of the explosion-proof film 20 from contamination. The adhesive 31 is also sticky and can adhere to contaminants, thereby preventing contaminants from entering the explosion-proof film 20.

[0030] Furthermore, the inner side of the adhesive 31 is a certain distance from the outer side of the explosion-proof film 20, and the adhesive 31 does not contact the explosion-proof film 20. Specifically, the inner side of the adhesive 31 is 2mm-3mm away from the outer edge of the explosion-proof film 20 it is close to, thereby avoiding contact between the adhesive 31 and the explosion-proof film 20. It should be noted that, in order to avoid the adhesive 31 sticking to the substrate 10 when peeling off the protective film 30, the adhesive strength of the side of the adhesive 31 that is attached to the protective film 30 is greater than the adhesive strength of the side of the adhesive 31 that is attached to the substrate 10. When it is necessary to peel off the explosion-proof film 20 for attachment to the display product, the protective film 30 is first peeled off from the substrate 10 so that the protective film 30 is separated from the surface of the explosion-proof film 20, and then the explosion-proof film 20 is peeled off.

[0031] Furthermore, the explosion-proof film 20 includes a heavy release film 21, a PET layer 22 and an OCA adhesive layer 23 arranged sequentially from top to bottom. The OCA adhesive layer 23 is adhesive. The explosion-proof film 20 is adhered to the substrate 10 through the OCA adhesive layer 23, and the protective film 30 covers the surface of the heavy release film 21.

[0032] Furthermore, to enhance the anti-fouling ability of the explosion-proof film 20, a self-cleaning dustproof layer 24 is provided between the PET layer 22 and the OCA adhesive layer 23. The self-cleaning dustproof layer 24 is extruded from transparent nano-titanium dioxide particles. The self-cleaning dustproof layer 24 has a self-cleaning effect, which makes the explosion-proof film 20 have strong hydrophobic, oil-resistant, and fingerprint-resistant capabilities, so that when the explosion-proof film 20 is attached to the display product, the display product can maintain a clean and bright effect for a long time.

[0033] This invention covers the surface of the explosion-proof film 20 with a protective film 30, and the inner periphery of the protective film 30 is provided with adhesive 31. The adhesive 31 surrounds the outer edge of multiple explosion-proof films 20 near the outer edge of the substrate 10, so as to protect the outer edge of the explosion-proof film 20 from contaminants. The adhesive 31 is sticky and can stick to the contaminants, thereby preventing contaminants from entering the explosion-proof film 20, ensuring the cleanliness of the explosion-proof film 20, and thus avoiding adverse effects on the display product.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
