Description

Antistatic PET net protection film

Technical Field

The utility model relates to an antistatic PET net protection film especially relates to gluing agent and electron technical field.

Background

With the continuous development of electronic technology and the continuous progress of the die cutting industry of electronic components, the requirements on various raw materials for die cutting of electronic elements are higher and higher, and the additional functional requirements on protective films for the process are higher and higher.

For protecting and discharging materials in the electronic die cutting industry, static electricity can be generated in the stripping process of the die cutting completion from the surface of a component, and the electronic component can be damaged in serious cases to cause loss. More serious surfaces can generate static electric sparks to cause more serious consequences.

Meanwhile, due to the fact that the multi-layer materials can be compounded simultaneously in the die cutting process, more than two materials can be compounded and attached, the adhesive tape products with high peeling force can be attached frequently in the process, and therefore a layer of release substances is required to be added on the non-adhesive surface of the protective film for the process to prevent adhesion and glue overflow.

In order to reduce the number of composite layers of a bonding material, it is now required that a single material has as many functions as possible. At present, most materials on the market only have a single protection function, and the influence on the composite multilayer structure is little considered.

When multiple layers of materials are laminated, air is present between the layers of materials after lamination due to the nature of the equipment and the materials themselves. The air bubbles can have adverse effects on the surface of the material after die cutting, and can damage the performance of the material in serious cases, and finally the product is scrapped.

Disclosure of Invention

The utility model discloses a solve above-mentioned problem, provide an antistatic PET protection film.

The utility model adopts the technical proposal that:

the utility model provides an antistatic PET net protection film which is characterized in that from last to once down: the first layer of grid is from type layer, second antistatic layer, third layer PET substrate layer, fourth layer of grid organosilicon adhesive layer, fifth layer are from type layer.

The first grid release layer is formed by curing at high temperature on the second antistatic layer through a gravure roller to form a layer of small molecule silicone oil substance with a grid structure, and the thickness of the small molecule silicone oil substance is 0.5-3 mu m, and the preferable thickness is 1 mu m. The adhesive tape adhered to the upper layer of the protective film can be easily removed while static electricity is eliminated, and the phenomenon that adhesive force is too large and adhesive overflows, and the adhered gas is rapidly exhausted after adhesive tape products and other adhesive products are adhered is avoided. Can effectually avoid the bubble to produce when carrying out multilayer structure stack laminating, the production of effectual reduction defective products.

The second layer is an antistatic layer which is directly on the PET substrate through a dimpleThe roller is coated to a thickness of about 0.1-0.5 μm, preferably 0.2 μm, and the micro-concave roller has a mesh size of 150-200 mesh, and has a surface resistance value of 10⁴-10¹⁰Ω。

The third layer is a PET substrate layer, namely a polyester film layer, and has the thickness of 20-200 μm, and the preferable thickness of 36-75 μm.

The fourth layer is a grid organic silicon adhesive layer, is formed by coating a layer of organic silicon substance below the PET film, and can be attached to the surface of a die-cutting component. The thickness of the organic silicon adhesive layer is about 5-20 μm, the preferred thickness is 10-15 μm, and the grid size formed by coating through a gravure printing roller is between 100 and 300 μm. The grid organic silicon adhesive layer can be used for effectively applying and bonding protected electronic components, and has a good exhaust performance due to the fact that the grid organic silicon adhesive layer has a grid structure.

The fifth layer is a laminating release film layer, the thickness is 20-50 μm, and the preferable thickness is 25-40 μm. The fluoroplastic release film or the non-silicon release film is attached to the surface of the adhesive layer to protect the adhesive surface, and the preferable release film is the fluoroplastic release film.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

1. the utility model discloses a coating antistatic layer on traditional PET protection film compares traditional for-process protection film, can effectual reduction the electrostatic effect that produces when peeling off the protection film to reduce because the production of static is to the destruction that the electronic components of cross cutting caused.

2. The utility model discloses a coating one deck release layer material again on antistatic PET protection film, multilayer components and parts can be compounded when laminating cross cutting piece, the phenomenon of overflowing glue that the sticky tape that can effectually prevent the upper laminating produced when guaranteeing the cross cutting process ensures that the upper adhesive tape can separate easily with lower floor cross cutting piece simultaneously.

3. The utility model discloses a to silica gel gluing agent layer and carry out the meshing processing from the type layer, the effectual bubble that produces of solution in the protective film laminating process is to the influence of being pasted the thing, the timely effectual discharge of air that produces in the in-process of will laminating.
