Description

Mylar gasket with adhesion function

Technical Field

The utility model relates to a wheat draws gasket technical field, especially relates to a wheat draws gasket with adhesion function.

Background

The Mylar film is a polyester film material, the long-term use temperature can reach 120 ℃, but the corona resistance is poor, the creep resistance, the fatigue resistance, the friction resistance and the dimensional stability are good, and the Mylar film can be used as an insulating material for motors, capacitors, coils and cables after being processed, and can also be made into a composite insulating material with highland barley paper.

The surface of the existing household appliance needs to be adhered with a large-area gum product, in particular to Mylar. The existing Mylar film is completely back-glued on the back surface and is stuck on the surface of an electronic product, and when the Mylar film is stuck on the surface, air is trapped inside the Mylar film easily, and air cannot be discharged to generate bubbles, so that the quality of the Mylar film is influenced. Even if the Mylar film is stuck from one side and rolled by a roller while being stuck, the air is difficult to be discharged, the operation is complicated, the cost is high, and air bubbles are generated.

Therefore, it is necessary to design a mylar gasket having an adhesion function to solve the above problems.

The utility model aims at solving the defects existing in the prior art and providing a Mylar gasket with an adhesion function.

In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides a wheat draws gasket with adhesion function, includes that wheat draws the gasket body, the bottom surface of wheat draws the gasket body is provided with antistatic backing, the top surface of wheat draws the gasket body is provided with glues and the glue film, the top surface of gluing and the glue film is provided with the shielding layer, the top surface of shielding layer is provided with the adhesion layer, the last viscose of adhesion layer is provided with the interval between protruding circular arc formula and each viscose, the top surface bonding of adhesion layer has from the type paper layer.

Preferably, be provided with the protruding package corresponding with the viscose arch on the type paper layer, the side fixedly connected with of type paper layer draws paper.

Preferably, the bottom of the shielding layer is provided with a nylon braid, and the surface of the nylon braid at the bottom of the shielding layer is provided with a nickel-copper alloy layer.

Preferably, the adhesive layer is made of hot melt adhesive.

Preferably, the mylar gasket body is 0.2-0.3mm thick, and the anti-static layer is made of anti-static fibers.

Preferably, the thickness of the release paper layer is 0.015-0.025 mm.

The utility model discloses following beneficial effect has:

1. through setting up glue and glue film, shielding layer, glue and become a whole with mylar gasket body and shielding layer connection with the glue film for mylar gasket has fine shielding property, and the nickel-copper alloy has anticorrosive anti-oxidant function, makes mylar gasket's live time longer, and application scope is wider more.
