The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When embodiments of the present invention refer to the ordinal numbers "first", "second", etc., it should be understood that the operations are to be performed only for distinguishing between them, unless the context clearly dictates otherwise.
The double faced adhesive tape is a thin adhesive layer with two sticky sides, and release paper is arranged on two sides of the thin adhesive layer, and when the release paper is peeled, the thin adhesive layer on one side of the release paper can be adhered to the surface of an object. Conventionally manufactured double-sided adhesive tapes can be in the shape of a strip of any width. For the occasion of bonding with special shape, the conventionally manufactured double-sided adhesive tape needs to be cut. For example, in the occasion that the frame body and the shell of the mobile phone need to be bonded, the double-sided adhesive needs to be adhered to the periphery of the frame body to form a closed loop structure, and the double-sided adhesive needs to be removed from the middle of the closed structure; at this time, two methods can be adopted, firstly, as shown in fig. 1, the whole piece of double-sided adhesive tape with the length and width meeting the requirement of the mobile phone frame body size is hollowed, namely the surrounding closed annular double-sided adhesive tape 12 is retained, and the unnecessary part 11 in the middle is removed, so that great material waste is generated; the second method is, as shown in fig. 2, cutting the double-sided adhesive tapes, respectively adhering the double-sided adhesive tapes to the periphery of the mobile phone frame, so that a gap 13 exists between two adjacent double-sided adhesive tapes, and the existence of the gap obviously reduces the waterproof performance of the mobile phone.
The embodiment of the invention provides an integrated double-sided adhesive tape which can be suitable for any occasions needing non-linear double-sided adhesive tapes. For example, when the shape and size of the directly processed double-sided adhesive tape cannot meet special requirements, the integrated double-sided adhesive tape prepared by the embodiment of the invention can meet the requirements of specific shape and size.
The embodiment of the invention is described by taking the application in a terminal, such as the adhesion between a frame and a shell of a mobile phone as an example.
Example one
The embodiment of the invention provides a preparation method of an integrated double-sided adhesive tape.
FIG. 3 is a flow chart of a method according to an embodiment of the present invention. As shown in fig. 3, the preparation method of the one-piece double-sided tape according to the embodiment of the present invention includes the following steps:
101. removing the release film at the first edge of the first surface of the first strip-shaped double-sided adhesive tape and the release film at the second edge of the second surface of the second strip-shaped double-sided adhesive tape;
102. overlapping the part of the first edge-removed release film and the part of the second edge-removed release film with each other to form a first connecting part;
103. and activating the adhesive property of the first edge and the second edge of the first connecting part by an external excitation source, so that the first edge and the second edge are bonded and fused into a whole structure.
Fig. 4 is a schematic view of a preparation process of the integrated double-sided adhesive tape according to the embodiment of the invention. As shown in fig. 4, the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 are cut out according to the size of the mobile phone frame. The length of the first strip-shaped double-sided adhesive tape is less than or equal to the width of the mobile phone, the length of the first strip-shaped double-sided adhesive tape is preferably equal to the width of the mobile phone, the length of the second strip-shaped double-sided adhesive tape is less than or equal to the length of the mobile phone, and the length of the second strip-shaped double-sided adhesive tape is preferably equal to the length of the mobile; the width of the first strip-shaped double-sided adhesive tape and the width of the second strip-shaped double-sided adhesive tape can be set according to actual needs, for example: less than or equal to 3mm, preferably 2 mm.
After the double-sided adhesive tape is cut according to the required size, the release film at the edge of the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 for lap joint is removed, and the first connecting part 3 is formed by overlapping the part of the release film removed by the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2. Because the release film is removed from the two double-sided tapes, the two double-sided tapes are bonded together according to the position relationship when the two double-sided tapes are overlapped with each other to form the first connecting portion 3. At this time, the thickness of the first connecting portion 3 is the total thickness of the first strip-shaped double-sided tape 1 and the second strip-shaped double-sided tape 2.
At this time, the viscosity of the first connection portion 3 is activated by an external excitation source, so that the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 located at the first connection portion 3 are fused into a whole to form an integrated structure 4.
The embodiment of the present invention may be any double-sided tape with a characteristic to be activated, for example: the double-sided adhesive can be activated by heat, light, pressure or electricity.
The fusion is a process in which the glue surface material of the first strip-shaped double-sided tape 1 and the glue surface material of the second strip-shaped double-sided tape 2 in the first connection portion 3 mutually permeate and the thickness of the first connection portion 3 becomes thin, and as shown in fig. 5, for the first connection portion 3 receiving an external excitation source, the glue surface materials of the two strip-shaped double-sided tapes mutually permeate and fuse to form the integrated structure 4. At this time, since the adhesive surfaces of the two strips of double-sided adhesive tape mutually permeate, the original texture is destroyed, and a new texture structure is formed at the integrated structure 4, as shown by reference numeral 4 in fig. 4 and 5.
As will be understood by those skilled in the art, since the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 are double-sided adhesive tapes processed by the same process, and the textures of the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 are the same in the length direction, when the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 are overlapped at the edges as shown in fig. 5, the textures of the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 are perpendicular to each other, when the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 are subjected to, for example, the texture.
It should be noted that the texture of the integrated structure after being excited by the excitation source is different from the texture of the first strip-shaped double-sided adhesive tape 1 and the texture of the second strip-shaped double-sided adhesive tape 2, and may be indistinguishable by naked eyes, which need to be observed by a microscope, or may be directly seen by naked eyes, and whether the texture is directly distinguishable by naked eyes is related to the structure of the double-sided adhesive tape itself, which is not limited herein.
At this time, the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 are completely fused together, and the thickness of the integrated structure 4 is smaller than the total thickness of the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 which are mutually overlapped. When the thickness of the first strip-shaped double-sided adhesive tape 1 is equal to that of the second strip-shaped double-sided adhesive tape 2, the thickness of the integrated structure 4 is preferably equal to that of the first strip-shaped double-sided adhesive tape 1 and that of the second strip-shaped double-sided adhesive tape 2; when the thickness of the first strip-shaped double-sided adhesive tape 1 is not equal to the thickness of the second strip-shaped double-sided adhesive tape 2, the thickness of the integrated structure 4 is preferably equal to the thickness of the first strip-shaped double-sided adhesive tape or the thickness of the second strip-shaped double-sided adhesive tape 2.
By the method, the integrated double-sided adhesive tape with the special shape can be prepared, and a user can prepare the integrated double-sided adhesive tape with the required shape by utilizing the method provided by the embodiment of the invention according to actual needs.
The waterproof requirement of the terminal is increasing day by day at present, and is all right to the occasion of waterproof grade requirement more than IPX 7. By taking a mobile phone as an example, the preparation method provided by the embodiment of the invention can be used for preparing the integrated double-sided adhesive tape matched with the appearance size of the mobile phone frame body, and can ensure that the mobile phone frame body is tightly attached to the shell.
As for the integrated double-sided adhesive tape applied to the mobile phone frame, as shown in fig. 6, the embodiment of the present invention further includes a third strip-shaped double-sided adhesive tape 5 and a fourth strip-shaped double-sided adhesive tape 6.
According to the combination mode of the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2, the edge of the third strip-shaped double-sided adhesive tape 5 is overlapped at the edge of the second strip-shaped double-sided adhesive tape 2 in sequence, and the overlapped parts of the second strip-shaped double-sided adhesive tape 2 and the third strip-shaped double-sided adhesive tape 5 are activated through an external excitation source, so that the third strip-shaped double-sided adhesive tape 5 is combined with the first strip-shaped double-sided adhesive tape 1 and the second strip-shaped double-sided adhesive tape 2 into an integrated double-sided adhesive tape, the fourth strip-shaped double-sided adhesive tape 6, the third strip-shaped double-sided adhesive tape 5 and the edge of the first strip-shaped double-sided adhesive tape 1 are overlapped with each other in the same mode, excitation processing is performed through the external excitation source, and finally.
Here, the matching means that the length of the strip-shaped double-sided adhesive tape meets the bonding requirement in the aspect of the frame length or the frame width, the width of the strip-shaped double-sided adhesive tape meets the whole requirement of the mobile phone, and the internal structure of the mobile phone is not affected according to the bonding requirement of the mobile phone frame.
Based on the integrated double-sided tape prepared by the method, the embodiment of the invention also provides a waterproof assembly shown in fig. 7, and the waterproof assembly comprises the integrated double-sided tape prepared by the method and a frame body 0.

Because this integral type double faced adhesive tape closely fuses an organic whole through external excitation, seamless can guarantee the bonding seamless between cell-phone framework and the shell, and then has improved waterproof performance.
The embodiment of the invention also provides another preparation method of the waterproof terminal, wherein the integrated double-faced adhesive tape is directly prepared on the mobile phone frame body, and then the mobile phone shell is bonded with the mobile phone frame body to prepare the waterproof terminal.

Because the integral double faced adhesive tape is a seamless closed structure matched with the outline of the mobile phone frame body 0, after the frame body 0 is bonded with the shell, a path for water vapor, water drops or water flow to enter the mobile phone is closed, and the waterproof grade is improved.
In addition, because the parts of the two double-sided adhesive tapes which are mutually overlapped are subjected to excitation treatment, the parts which are mutually overlapped form an integral structure, the thickness of the parts is reduced, the parts are equivalent to the thickness of a single-layer double-sided adhesive tape, a gap is not formed between the frame body 0 and the frame body due to the thickness difference of the connecting part, the seamless close fit between the frame body 0 and the shell is further ensured, and the waterproof performance is improved.
