A carbon nanocoating release film having self-adsorption force according to an embodiment of the present invention is described below with reference to fig. 1 to 3.

As shown in fig. 1-3, the carbon nano-coating release film with self-adsorption capacity comprises a PET substrate 100, an adsorption layer 200 and a conductive layer 300, wherein the PET substrate 100 is used as a substrate of the release film, the adsorption layer 200 and the conductive layer 300 are respectively adhered to two sides of the PET substrate 100, the adsorption layer 200 is used for being adsorbed on the surface of an object, the release film can be covered on an adhering surface, the conductive layer 300 is used for leading out static electricity accumulated in the release film, the adsorption rate of surrounding dust is reduced in the use process of the release film, the release film is easier to adhere, and the production of bubbles is reduced.

Because the PET film is a polar electrical insulating material, the surface of the PET substrate 100 generates friction to form static electricity when being cut and rolled, the generated charges cannot be transferred, and the static electricity is accumulated on the surface of the PET substrate to form static electricity, so that certain static electricity is remained after the release film is produced. When the static charge accumulation on the release film, the dust on every side is constantly close to the surface from the type membrane under the attraction of static electricity, from the type membrane dyestripping in-process, can produce a large amount of static, makes the dust on every side be close to fast, and the easy adhesion of dust is on adsorbed layer 200 and binding face, leads to the laminating back, and the dust presss from both sides between binding face and adsorbed layer 200, forms the bubble. To the region of large tracts of land binding face such as screen panel, a large amount of dust bubbles can make screen panel from type membrane laminating effect relatively poor, and is not pleasing to the eye to make in the dust gets into the screen assembly from screen panel's side seam department easily, make the screen yields reduce, paste from type membrane to screen panel and need go on in the dust-free workshop, require highly to the production environment. And conducting layer 300 coating can derive from type membrane production electric charge at the dyestripping in-process from the surface of PET film, prevents from type membrane adhesion dust in the laminating process, has reduced the bubble quantity after the lamination from type membrane.

The release film further comprises an exhaust structure 500, wherein the exhaust structure 500 is arranged among the conductive layer 300, the PET substrate 100 and the adsorption layer 200, and the exhaust structure 500 is used for exhausting residual gas after lamination.

The carbon in the nano coating has excellent conductive capability, and the electrostatic charge accumulated on the release film can be effectively led out when the carbon is applied to the surface of the PET substrate 100. The coating thickness is not too thick or too thin, which results in the increase of the production cost of the release film, while the coating thickness is too thin, which results in the poor static electricity-guiding effect, in the embodiment, the thickness of 0.035mm is adopted, which achieves the proper balance between the cost control and the static electricity-removing effect.

It should be understood that the carbon nano coating 310 with a thickness of 0.035mm is not the only embodiment, but in other embodiments, different thicknesses may be selected according to the actual adhering surface area, the thickness of 0.02mm can be used when the adhering area is small, and the thickness of 0.05mm can be used when the adhering area is large.

The metal conductive strips 320 can adopt ultrathin metal strips or printed metal strips, the distance between every two metal conductive strips 320 is 30-50 mm, and due to the fact that the size of the screen area adhered by the release film is large or small, the metal conductive strips 320 adopt proper intervals, the usage amount of the metal conductive strips 320 can be reduced, and the manufacturing cost is reduced.

Specifically, the thickness of the metal conductive strip 320 is smaller than the thickness of the carbon nano-coating 310, so that after the carbon nano-coating 310 is coated on the surface of the PET substrate 100, the metal conductive strip 320 does not protrude out of the surface of the carbon nano-coating 310, and the surface of the carbon nano-coating 310 is flat and beautiful.

Specifically, the diameter of the air holes 510 is smaller than the width of the metal conductive strips 320, so as to prevent the air holes 510 from exceeding the two sides of the metal conductive strips 320, and thus air bubbles are trapped between the carbon nano-coating layer 310 and the PET substrate 100.
