DETAILED DESCRIPTION

[0023] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or components / elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] The following describes a method for forming a graphene adhesive protective cover according to an embodiment of the present application in conjunction with the accompanying drawings.

[0025] Figure 1 is an exploded view of a graphene adhesive protective case provided by an embodiment of the present application; Figure 2 : is a front and back view of a finished product of a graphene adhesive protective shell provided by another embodiment of the present application; wherein Figure 2 Part (a) is the back side. Figure 2 Part (b) in is the front side. Figure 1-2 As shown: the graphene adhesive protective shell includes a first polyethylene terephthalate film substrate 5, a pattern design printing layer 6 arranged below the first polyethylene terephthalate film substrate 5, a first glue bonding layer 7 arranged below the pattern design printing layer 6, a composite film layer 8 arranged below the first glue bonding layer 7, a graphene coating 9 arranged below the composite film layer 8, and a removable glue layer 10 arranged at the edge or four corners of the composite film layer 8 or the graphene coating 9.

[0026] Specifically, the first polyethylene terephthalate film substrate 5 uses polyethylene terephthalate as one of the substrates of the protective shell. The English name is Polyethylene Terephthalate, abbreviated as PET. PET has good mechanical properties, and its impact strength is 3 to 5 times that of other films, and it has good folding resistance. PET materials are widely used in the market, and have advantages in cost and performance. Usually PET is a roll material. In order to have a good scratch resistance effect on the surface, curing treatment and other treatments are usually performed on the PET surface. The composite film layer 8 can use amorphous polyethylene terephthalate, which is called Amorphous Polyethylene in English. Terephthalate, referred to as APET, has better low-temperature toughness and heat resistance than PET; the composite film layer 8 can also be made of other films; the material performance of APET is easier to hot-press and is also convenient for subsequent molding; the first PET film substrate 5, the pattern design printing layer 6 and the composite film layer 8 are composited together by glue, the purpose of which is to protect the internal pattern design printing layer 6 by the first PET film substrate 5 and the composite film layer 8. The pattern design printing layer 6 prints the pattern according to the product requirements, and it can prevent external wear inside the film. After the first PET film substrate 5, the pattern design printing layer 6, the first glue bonding layer 7 and the composite film layer 8 are composited, the shape of the unfolded plane of the shell is measured and calculated according to the size and shape of the product to be protected, and the die cutter is used to cut into pieces according to the measured size and shape.

[0027] The graphene coating 9 is designed with graphene conductive heat dissipation function. Usually, mobile phones, tablets, notebooks and other electronic products will generate heat during use. We use graphite to dissipate heat. The graphene coating 9 is set on the composite film layer 8. The graphene is directly attached to the surface of the product. The heat of mobile phones, tablets, laptops and other products is conducted through graphene.

[0028] The removable glue layer 10 is used to install and fix the composite graphene adhesive protective case on mobile phones, tablets, laptops and other products, replacing the buckles. In the past, it was installed by buckles, which were too tight. Nowadays, women love manicures, and heat pressure will damage nails during the decoration process, so we adopt the glue sticking method, which is easier to load and unload and not easy to damage nails.

[0029] It should be noted that during production and processing, the removable glue layer 10 can be pasted on the composite film layer 8 first, and then the graphene coating can be rolled on the composite film layer 8; specifically, because the graphene is easy to fall off when the general glue is pasted on the graphene, and the removable glue is directly pasted on the surface of the composite film layer 8, the removable glue can be more closely pasted with the APET and not easy to fall off. It is also possible to paste the graphene on the composite film layer 8 first to form the graphene coating 9, and then paste the removable glue layer 10 on the graphene coating 9; it should be noted that this operation requires the use of modified graphene for pasting, so that the graphene coating 9.

[0030] After the material stacking, removable adhesive and graphene rolling processes are completed, the mold can be used for hot pressing. The film cut into appropriate thickness is placed in the mold and baked on a baking tray to soften the film, and then combined in the mold to form.

[0031] According to a graphene adhesive protective case of the present application, a pattern is printed on the protective case, and the pattern is well protected and not easy to wear; and heat is dissipated by graphene, so that the electronic device used can dissipate heat well; and removable glue is used for bonding to prevent damage to the user's nails.

[0032] According to one embodiment of the present application, a mirror / frosted coating 4 is disposed above the first polyethylene terephthalate film substrate 5 .

[0033] Specifically, the mirror / frosted coating 4 is used to give the product a frosted texture and a flat mirror effect, making the product surface effect richer.

[0034] According to one embodiment of the present application, an anti-scratch coating 3 is disposed on the first polyethylene terephthalate film substrate 5 .

[0035] Specifically, the anti-scratch coating 3 can further improve the anti-scratch performance of the product.

[0036] According to one embodiment of the present application, a second glue bonding layer 2 is provided above the first polyethylene terephthalate film substrate 5, or the mirror / matte coating 4, or the anti-scratch coating 3, and an anti-drop silicone frame 1 is provided above the second glue bonding layer 2.

[0037] Specifically, the anti-drop silicone frame 1 is formed into a component by designing different frame shapes, and a second glue adhesive layer 2 is attached to the back of the silicone frame, and the other glue surface of the second glue adhesive layer 2 is directly attached to the periphery of the formed shell. The second glue adhesive layer 2 can be a removable glue.

[0038] Figure 3 FIG. 1 is a schematic diagram of a composite film layer of a graphene adhesive protective shell provided by an embodiment of the present application. Figure 3As shown: the composite film layer 8 includes a non-crystallized polyethylene terephthalate or polyethylene terephthalate-1,4-cyclohexanedimethanol film substrate 801 at the top, a third glue bonding layer 802 arranged in the middle, and a second polyethylene terephthalate film substrate 803 arranged at the bottom.

[0039] Specifically, polyethylene terephthalate-1,4-cyclohexanedimethylene ester, the full name of which is Poly (ethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate), referred to as PETG. PETG sheet has outstanding toughness and high impact strength, and has a wide processing range, high mechanical strength and excellent flexibility. Compared with PVC, it has high transparency, good gloss, is easy to print and is an environmentally friendly material. APET / PETG film substrate 801 selects one of APET or PETG, and then adheres the second PET film substrate 803 through the third glue bonding layer 802. This is because PET is more scratch-resistant than APET or PETG, and the PET material protects the material on the inside on the outside, while APET or PETG has better mechanical properties. Therefore, the sheet composited in this way has a scratch-resistant surface and better mechanical properties at a thinner thickness.

[0040] According to one embodiment of the present application, the thickness of the composite film layer 8 is 0.3-1.0 mm.

[0041] According to an embodiment of the present application, the thickness of the composite film layer 8 is 0.5-0.8 mm.

[0042] According to one embodiment of the present application, the thickness of the first polyethylene terephthalate film substrate 5 is 0.025-0.25 mm.

[0043] According to an embodiment of the present application, the thickness of the first polyethylene terephthalate film substrate 5 is 0.075-0.125 mm.

[0044] Specifically, lightness and thinness are the hot selling points in the market, and users are more inclined to purchase lightness and thinness products. Therefore, under the premise of ensuring sufficient strength, the first PET film substrate 5 and the composite film layer 8 are selected to have appropriate sizes, which can solve the problem of lightweight product demand.

[0045] The first PET film substrate 5 can have a wide range of available thicknesses, such as 0.025, 0.05, 0.075, 0.125, 0.188, 0.25 mm, etc. In the current embodiment, the two types with better test results are 0.075 mm and 0.125 mm.

[0046] The composite film layer 8 can be a single APET film, or a composite of an APET / PETG film substrate 801, a third glue bonding layer 802 and a second PET film substrate 803. The single APET film or the APET / PETG film substrate 801 can be one of a variety of thicknesses, including 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 mm, etc. In the current embodiment, 0.4 mm or 0.5 mm is preferred; the second PET film substrate 803 can be one of a variety of thicknesses, including 0.025, 0.05, 0.075, 0.125, 0.188, 0.25 mm, etc. In the current embodiment, 0.075 mm or 0.125 mm is preferred.

[0047] According to one embodiment of the present application, the graphene adhesive protective shell is provided with a plurality of exhaust holes.

[0048] Specifically, a laptop computer is usually formed of an upper cover and a lower cover, and the production process of the upper and lower covers is the same process, but usually there are exhaust holes. Therefore, when the graphene adhesive protective case of the present application is used for a laptop computer protective case, exhaust holes can be punched on the product using a mold.

[0049] According to one embodiment of the present application, silicone anti-skid pads are provided at four corners on the first polyethylene terephthalate film substrate 5 , or the mirror / matte coating 4 , or the anti-scratch coating 3 .

[0050] Specifically, when the graphene adhesive protective cover of the present application is used for the lower cover of a laptop computer, a silicone anti-skid pad can be added.

[0051] The above embodiments are preferred implementation schemes of the present application. In addition, the present application may also be implemented in other ways. Any obvious replacement without departing from the concept of the present application is within the protection scope of the present application.
