Background
The adhesive tape for electronic materials has various types, and relates to the fields of the electronic industry. The PET double-sided adhesive tape is prepared by coating acrylic adhesive on both sides of PET (polyethylene terephthalate). The tape is generally transparent and black in color. Common thickness specifications are: 0.03-0.25MM, and has good dimensional stability, thermal stability and chemical stability. Good initial viscosity and adhesive holding capacity, easy die cutting and processing, and good viscosity for plastic cement, rubber and nameplates. Can be applied to wider temperature range and severe environment. The temperature can be 100-120 ℃ for a long time and can reach 140-200 ℃ for a short time. The PET double faced adhesive tape is mainly used for bonding parts and shells of transformers, televisions and recorders, and can also be used for bonding PET film sheets and related PET materials. And touch screens applied in modern industries have the problems that common ultrathin PET double-sided adhesive tapes have very good adhesion and surface flatness, but bubbles are easy to generate and difficult to discharge during lamination, and the lamination is difficult to directly realize, so that the reject ratio is high or manpower and material resources are wasted.
SUMMERY OF THE UTILITY MODEL
Accordingly, it is necessary to provide a PET exhaust tape in order to solve the problem that bubbles are not easily discharged when conventional PET double-sided tapes are attached.
A PET vented tape comprising: from type rete, first acrylic acid pressure sensitive adhesive layer, PET substrate layer, second acrylic acid pressure sensitive adhesive layer and single face net leave type rete, the surface of two oppositions of PET substrate layer has been laminated respectively first acrylic acid pressure sensitive adhesive layer with second acrylic acid pressure sensitive adhesive layer, the surface that first acrylic acid pressure sensitive adhesive layer deviates from the PET substrate layer is laminated and is had from type rete, the surface that second acrylic acid pressure sensitive adhesive layer deviates from the PET substrate layer is laminated and is covered single face net is from type rete, single face net is the net face from one of them surface on type rete, single face net leave type rete the net face with second acrylic acid pressure sensitive adhesive layer contacts.
The single-side grid release film layer of the PET exhaust adhesive tape can form grid stripes on the second acrylic pressure-sensitive adhesive layer, and the grid stripes form an exhaust structure. This facilitates the venting of gas between the second acrylic pressure sensitive adhesive layer and the surface of the object.
In one embodiment, the thickness of the first acrylic pressure sensitive adhesive layer is 0.006mm to 0.06 mm.
In one embodiment, the thickness of the second acrylic pressure sensitive adhesive layer is 0.006mm to 0.06 mm.
In one embodiment, the thickness of the PET exhaust adhesive tape is 0.03mm-0.3 mm.
In one embodiment, the thickness of the PET exhaust tape is 0.03 mm.
In one embodiment, the PET substrate layer is a polyester glass fiber cloth film.
In one embodiment, the PET vented tape has a tack greater than 1200 g.

Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, an embodiment of the present invention provides a PET exhaust tape 100, which includes: a release film layer 110, a first acrylic pressure sensitive adhesive layer 120, a PET substrate layer 130, a second acrylic pressure sensitive adhesive layer and a single-sided mesh release film layer 150. The two opposite surfaces of the PET substrate layer 130 are respectively coated with the first acrylic pressure sensitive adhesive layer 120 and the second acrylic pressure sensitive adhesive layer. The surface of the first acrylic pressure-sensitive adhesive layer 120 departing from the PET substrate layer 130 is coated with the release film layer 110. The surface of the second acrylic pressure sensitive adhesive layer departing from the PET substrate layer 130 is coated with the single-sided mesh release film layer 150. One surface of the single-sided mesh release film layer 150 is a mesh surface, and the mesh surface of the single-sided mesh release film layer 150 is in contact with the second acrylic pressure sensitive adhesive layer.
The single-sided grid release film layer 150 of the PET venting tape 100 described above may form grid stripes on the second acrylic pressure sensitive adhesive layer, which form the venting structure. This facilitates the venting of gas between the second acrylic pressure sensitive adhesive layer and the surface of the object.
In this embodiment, the thickness of the first acrylic pressure sensitive adhesive layer 120 is 0.006mm to 0.06 mm. For example, the thickness of the first acrylic pressure-sensitive adhesive layer 120 may be 0.006mm,0.008mm,0.01mm,0.05mm, or the like.
