keep away from the type rete the even a plurality of swallow-tailed sand grip that are equipped with in one side of antistatic layer, adjacent two all be equipped with the clearance groove between the swallow-tailed sand grip, the coating has easily to tear the glue film in the clearance groove.

In a further aspect, the surface layer is a titanium dioxide surface layer.

The further proposal is that the antistatic layer is a silicate antistatic layer.

The further scheme is that the easily torn glue layer is EVA hot melt glue.

The further proposal is that a cavity is arranged in the release film layer; a plurality of elastic columns are further mounted inside the cavity, and two ends of the elastic columns are connected with the upper end and the lower end of the cavity respectively.

The further scheme is that the thickness of the release film layer is twice of that of the surface layer.

The utility model has the advantages that:

the antistatic layer is arranged on the upper surface of the release film layer, so that the problem that the release film adsorbs dust due to static electricity can be solved; the upper surface of the surface layer is provided with the oleophobic bulge, so that oil stains can be prevented from being stuck to the surface of the release film, and the stain resistance of the release film is improved;

the dovetail type convex strips and the easily torn glue layer are arranged on the lower surface of the release film layer at intervals, so that the bonding area between the release film and the connecting piece is effectively reduced, the release film is conveniently torn and peeled, the release film is prevented from being excessively bonded on the surface of the connecting piece, and the convenience of replacement of the release film is improved;

set up the cavity and at cavity internally mounted elasticity post from type rete, improved from compressive capacity in the type membrane, strengthened from the elasticity of type membrane.

Drawings

Fig. 1 is a schematic structural view of an ultra-light release film special for OCA in the embodiment of the present invention;

the attached drawings are marked as follows: 1-a surface layer; a 10-oleophobic projection; 2-an antistatic layer; 3-a release film layer; 30-a cavity; 31-an elastic column; 4-dovetail type convex strips; 5-a clearance groove; 6-easily torn glue layer.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, one embodiment of the present invention discloses an ultra-light release film for OCA, which includes a surface layer 1, an antistatic layer 2 and a release film layer 3;

the lower surface of the surface layer 1 is bonded with the upper surface of the antistatic layer 2; the lower surface of the antistatic layer 2 is bonded with the upper surface of the release film layer 3;

the upper surface of the surface layer 1 is provided with an oleophobic convex part 10, and the cross section of the oleophobic convex part 10 is arc-shaped;
