Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "right", etc. are used in an orientation or positional relationship based on that shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes to distinguish one from another.

As shown in fig. 1, the utility model provides an antistatic self-adhesive label, which comprises a backing paper 1, a surface paper 2, a waterproof film 3 and a conductive edge banding 33. Wherein the waterproof membrane 3 covers the surface paper 2, and the two sides of the waterproof membrane 3 are sprayed with antistatic coatings; the edge of the waterproof film 3 is wrapped by the conductive seal edge 33, and two sides of the conductive seal edge 33 are respectively in contact with the antistatic coatings on two sides of the waterproof film 3.

This antistatic non-setting adhesive label is through setting up two-layer antistatic film and connecting two-layer antistatic film with electrically conductive banding 33, increases the content of antistatic agent in the antistatic film, obtains better antistatic effect. Meanwhile, the waterproof film 3 is adopted to improve the waterproof capability of the antistatic self-adhesive label.

Embodiments of the present embodiment will be described below with reference to the drawings.

As shown in fig. 1, the antistatic self-adhesive label in this embodiment includes a base paper 1 and a face paper 2, wherein a silicone oil layer 11 is coated on an upper surface of the base paper 1, a first glue layer 21 is coated on a lower surface of the face paper 2, and the base paper 1 and the face paper 2 are adhered by the first glue layer 21.

The upper surface of the face paper 2 is also bonded with a waterproof film 3 through a second glue layer 22, two sides of the waterproof film 3 are respectively sprayed with a first anti-static coating 31 and a second anti-static coating 32, the edge of the waterproof film 3 is also wrapped with a conductive edge sealing 33, two sides of the conductive edge sealing 33 are respectively contacted with the anti-static coatings on two sides of the waterproof film 3, so that electrons can be freely transferred between the first anti-static coating 31 and the second anti-static coating 32, obviously, compared with a common single-side spraying anti-static coating, the two-side spraying anti-static coating is adopted, the content of an anti-static agent in the anti-static coating is more, and a better anti-static effect is obtained.

In this embodiment, in order to make the waterproof film 3 have a good waterproof performance and ensure that the first antistatic coating 31 and the second antistatic coating 32 are firmly attached to the surface of the waterproof film 3, the material of the waterproof film 3 is preferably graft-modified polypropylene. The polypropylene resin molecule is in a non-polar crystal linear structure, and has low surface activity and no polarity. Poor surface printability exists; poor coating and bonding; difficult to blend with polar polymers; the polar reinforcing fiber and the filler are difficult to be compatible. The grafting modification is to introduce polar groups into the macromolecular chain of the polypropylene so as to improve the blending property, the compatibility and the cohesiveness of the polypropylene and overcome the defects of difficult blending, difficult compatibility and difficult bonding. Under the action of an initiator, grafting reaction is carried out on a grafting monomer during melting and mixing, the initiator is decomposed to generate active free radicals when heated during heating, melting and heating, when the active free radicals meet unsaturated carboxylic acid monomers, unstable bonds of the unsaturated carboxylic acid monomers are promoted to be opened and then react with the active free radicals of polypropylene to form the grafting free radicals, and then the grafting free radicals are terminated through molecular chain transfer reaction. The hydrogen atoms in the grafted and modified PP molecular chain are replaced to present stronger polarity, and the polar groups enhance the compatibility of the polypropylene and greatly improve the heat resistance and the mechanical property.

In this embodiment, in order to ensure that the conductive sealing edge 33 has better conductivity, the conductive sealing edge 33 is made of conductive metal or conductive plastic. It is easily conceivable that in other embodiments, the conductive edge seal 33 can be replaced by a conductive metal wire or a conductive plastic strip connecting the first and second

antistatic coatings

31 and 32.

To sum up, this antistatic non-setting adhesive label is through setting up two-layer antistatic film and connecting two-layer antistatic film with electrically conductive banding 33, increases the content of antistatic agent in the antistatic film, obtains better antistatic effect. Meanwhile, the waterproof film 3 is adopted to improve the waterproof capability of the antistatic self-adhesive label.
