SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of high manufacturing cost and easiness in generating bubbles in the prior art, and provides a back-adhesive PET Mylar film of electronic equipment.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a gum PET Mylar film of an electronic device comprises a Mylar film body, wherein a first gum layer and a second gum layer are respectively bonded on the top of the Mylar film body;
the first back glue layer is in a transverse U shape, and the second back glue layer is in a curve shape;
first gum layer and second gum layer all are provided with two and symmetrical arrangement, two first gum layer is located the top both sides of Mylar film body, two the second gum layer is located the middle part of Mylar film body upper surface.
Preferably, the first release layer and the second release layer are respectively bonded to the tops of the first back glue layer and the second back glue layer.
Preferably, the first release layer and the second release layer are provided with a delay part of an integrated structure at the end part thereof.
Preferably, the first release layer is provided with two and separately arranged at two sides of the second release layer.
Preferably, two all set up a plurality of on the first gum layer and be the exhaust hole that the array distributes, two all set up a plurality of along curve interval distribution's air discharge duct on the second gum layer.
The utility model has the beneficial effects that:
1. according to the Mylar film, the two back adhesive layers are adhered to the Mylar film through the arrangement of the first back adhesive layer and the second back adhesive layer, the first back adhesive layer is distributed on the edge of the Mylar film, and the second back adhesive layer is uniformly distributed in the middle of the Mylar film in a curved shape, so that the Mylar film can be stably adhered to electronic equipment, the use of back adhesive materials is reduced, and the manufacturing cost is saved.
2. According to the Mylar film, the vent holes and the vent grooves are formed in the back adhesive layer respectively through the arrangement of the vent holes, the vent grooves and the like, so that air between the back adhesive layer and the Mylar film can be discharged, bubbles generated by the Mylar film and the back adhesive layer are avoided, and the quality of the Mylar film is improved.

Detailed Description
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.
Referring to fig. 1-4, the adhesive-backed PET mylar sheet of an electronic device comprises a mylar sheet body 1, wherein a first adhesive layer 2 and a second adhesive layer 3 are respectively bonded to the top of the mylar sheet body 1; the first back glue layer 2 is in a transverse U shape, and the second back glue layer 3 is in a curve shape; first gum layer 2 and second gum layer 3 all are provided with two and symmetrical arrangement, and two first gum layers 2 are located the top both sides of wheat pulling-on piece body 1, and two second gum layers 3 are located the middle part of 1 upper surface of wheat pulling-on piece body.
Wherein, setting through first gum layer 2 and second gum layer 3, the two parts gum layer bonding has been adopted on the Mylar piece, first gum layer 2 distributes at the Mylar piece edge, second gum layer 3 is the middle part of curve form evenly distributed at the Mylar piece, can make the Mylar piece bond on electronic equipment steadily, and the material that has reduced the gum uses, manufacturing cost has been saved, setting through exhaust hole 21 and air discharge duct 31 isotructure, set up exhaust hole 21 and air discharge duct 31 respectively on the gum layer, can be used for discharging the air between gum layer and the Mylar piece, avoided Mylar piece and gum layer to produce the bubble, the quality of Mylar piece has been promoted.
First gum layer 2 and 3 tops of second gum layer bond respectively have first type layer 4 and second from type layer 5, first type layer 4 and the second is provided with the time delay portion of integrated into one piece structure jointly from the tip on type layer 5, first type layer 4 is provided with two and divides the both sides of putting from type layer 5 at the second, all set up a plurality of on two first gum layers 2 and be the exhaust hole 21 of array distribution, all set up a plurality of on two second gum layers 3 along curve interval distribution's exhaust groove 31.
