Description
Technical Field
The utility model relates to an sticky tape technical field specifically is a but frameless display panel is with PU bubble cotton adhesive tape of doing over again.
Background
The adhesive tape is an article consisting of a base material and an adhesive, two or more unconnected objects can be connected together through adhesion, the adhesive tape can be divided into a high-temperature adhesive tape, a double-sided adhesive tape, an insulating adhesive tape, a special adhesive tape, a pressure-sensitive adhesive tape and a die-cutting adhesive tape according to the efficacy of the adhesive tape, and different efficacies are suitable for different industry requirements.
The existing display panel usually uses a film adhesive tape, but after the adhesive tape is bonded, if the film adhesive tape is wanted to be torn off, residual adhesive is easy to remain, and the reworking or the reworking is very inconvenient, so a reworkable PU foam adhesive tape for the frameless display panel is provided.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model discloses a but frameless display panel reworks PU bubble cotton adhesive tape to solve the problem that provides among the above-mentioned background art.
(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a reworkable PU foam tape for a frameless display panel, comprising:
the adhesive comprises a first adhesive layer and a second adhesive layer, wherein the first adhesive layer and the second adhesive layer are both provided with PSA adhesives;
the foam layer is set to be foam PUR foam, and is adhered to the lower surface of the first adhesive layer;
the base material layer is a PET film, the base material layer is compositely connected to the lower surface of the foam layer, and the base material layer is bonded to the upper surface of the second glue layer;
and the release film is adhered to the lower surface of the second adhesive layer.
Preferably, the first adhesive layer and the second adhesive layer are both black.
Preferably, the foam layer is provided with a plurality of micropores which are communicated up and down.
Preferably, the release film is a double-sided release film.
The utility model discloses a but frameless display panel is with PU bubble cotton adhesive tape of doing over again, its beneficial effect who possesses as follows:
1. this but frameless display panel is with PU bubble cotton tape of doing over again forms through the first glue film, the cotton layer of bubble, substrate layer and the second glue film complex that sets up, and compression deformation is low, and sealing performance is good, and is able to bear or endure the impact force well, bonds firmly, has both fine viscidity and can disassemble portably again when needing to do over again or reprocess, guarantees when needing to dismantle and reprocess that it gets rid of easily not the cull, tears the back surface and does not have the cull (removability is good) protection module and does not receive the damage.
2. The reworkable PU foam adhesive tape for the frameless display panel has the advantages that the first adhesive layer and the second adhesive layer are both black, and the reworkable PU foam adhesive tape can be used for products needing to be bonded or protected from light in various industries.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a first glue layer; 2. soaking a cotton layer; 3. a substrate layer; 4. a second adhesive layer; 5. and (4) a release film.
Detailed Description
The embodiment of the utility model discloses but frameless display panel is with PU bubble cotton tape of doing over again, as shown in figure 1, include:
the adhesive comprises a first adhesive layer 1 and a second adhesive layer 4, wherein the first adhesive layer 1 and the second adhesive layer 4 are both provided with PSA adhesives;
the foam layer 2 is set to be foam PUR foam, and the foam layer 2 is bonded on the lower surface of the first adhesive layer 1;
the base material layer 3 is a PET film, the base material layer 3 is compositely connected to the lower surface of the foam layer 2, and the base material layer 3 is bonded to the upper surface of the second glue layer 4;
and the release film 5 is adhered to the lower surface of the second adhesive layer 4.
The first glue layer 1 and the second glue layer 4 are both set to be black.
The foam layer 2 is provided with a plurality of micropores which are communicated up and down.
The release film 5 is a double-sided release film.
The working principle is as follows: before use, all contact surfaces are clean and free of dirt or other pollutants, the first adhesive layer 1 and the second adhesive layer 4 are pressure-sensitive adhesives, certain pressure must be applied during use, otherwise, defects can be caused, adhesive films have obvious unevenness or distortion and can be bonded poorly, and the surfaces are smooth before use;
in the using process, the release film 5 is firstly torn off, and then the adhesive tape is stuck between two proper articles through the first adhesive layer 1 and the second adhesive layer 4, so that an effective adhesion effect is achieved;
through the first glue film 1 that sets up, the cotton layer 2 of bubble, substrate layer 3 and the compound formation of second glue film 4, compression deformation is low, and sealing performance is good, and is resistant impact force good, and it is firm to bond, has both had fine viscidity and can disassemble simple and convenient again when needs rework or reprocess, guarantees when needs are dismantled and reprocess that it gets rid of easily not the cull, tears the no cull in rear surface (removability is good) protection module and does not receive the damage.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
