technical field

The invention relates to the technical field of adhesive tapes, in particular to an antistatic adhesive tape.

Background technique

At present, anti-static tape is a general-purpose electronic packaging material, which is widely used in the packaging process of electronic products. It can not only seal the integrated circuit to isolate the external environment, but also usually has an anti-static function to avoid Static electricity can damage integrated circuits. Generally, the packaging tape is a laminated structure, which includes a substrate layer from bottom to top, and an adhesive layer on which the primary substrate layer is attached as a substrate for an aluminum-coated film layer. After processing, the aluminized film layer is pasted on the top surface of the sub-substrate layer to provide resistance. The antistatic adhesive tapes in the prior art are of single structure, and have disadvantages such as no optical properties, no waterproof performance, unsatisfactory antistatic performance, difficult to tear off, and no environmental protection.

The utility model with Chinese application number 2013206841834 discloses an antistatic light-shielding adhesive tape. The adhesive tape includes a substrate, a light-shielding layer, an adhesive layer, an antistatic layer, and a peeling layer. The thickness of the substrate is 3-210um. The thickness of the light-shielding layer is 2-39um, an antistatic layer is arranged between the light-shielding layer and the adhesive layer, the antistatic layer and the light-shielding layer are connected by adhesive, and the thickness of the antistatic layer is smaller than that of the base material The thickness of the antistatic layer is 3-45um, the thickness of the peeling layer is 7-210um, the thickness of the adhesive layer is 2-66um, the light-shielding layer is coated on the surface of the substrate, the The light-shielding layer is reflective, the adhesive layer is a pressure-sensitive adhesive layer, the adhesive layer is coated on the surface of the light-shielding layer, the peeling layer is connected to the adhesive layer, and the adhesive layer is connected to the light-shielding layer. The viscosity is greater than the viscosity between the adhesive layer and the release layer. The invention is provided with a light-shielding layer under the base layer, which has optical properties, can be used in specific occasions, and expands the scope of use of antistatic adhesive tapes, but still has the following disadvantages: First, the utility model is not provided with a waterproof protection device, and the adhesive tape is exposed to water. Finally, the antistatic performance will be weakened or even damaged, which will affect the use of the tape; secondly, the utility model is not equipped with a tearing device, and auxiliary tools are needed to tear the tape, which affects work efficiency; thirdly, the antistatic layer is a single structure , resulting in unsatisfactory antistatic performance and low overall performance of the tape.

Contents of the invention

Aiming at the deficiencies in the prior art, the invention provides an antistatic adhesive tape with simple structure and waterproof performance.

In order to achieve the above object, the technical scheme that the present invention takes:

An antistatic tape, comprising a tape body, the tape body is sequentially provided with a base layer, a light-shielding layer, an antistatic layer, and an adhesive layer from top to bottom, and a waterproof layer is provided above the base layer, and the thickness of the waterproof layer is less than The thickness of the base layer.

As a preferred technical solution, in order to facilitate the tape to be easily torn during use, reduce trouble during work, and effectively improve work efficiency, the tape body is evenly provided with a tearing structure that runs through the tape body.

As a preferred technical solution, in order to ensure the antistatic performance of the antistatic layer and effectively improve the overall performance of the tape, the antistatic layer is a composite layer of a multi-layer structure, and from top to bottom is a solidified electrostatic liquid layer, polyimide film layer.

As a preferred technical solution, in order to reduce the impact on the environment caused by the use of anti-static tape, and to be conducive to environmental protection, the base layer is a composite layer with a multi-layer structure, and from top to bottom are soft plastic film layers, bonding glue layer, hard plastic film layer.

Compared with the prior art, the present invention has the beneficial effects:

1. There is a waterproof layer on the base layer, which has waterproof performance and can effectively avoid the weakening of the antistatic performance after the tape is exposed to water. It is suitable for various occasions and has a wide range of applications.

2. Set the tearing structure through the tape body, which is convenient for the tape to be easily torn during use, reduces work troubles, and effectively improves work efficiency.

3. Set the antistatic layer composed of solidified electrostatic liquid layer and polyimide film layer, double antistatic layer, which effectively improves the antistatic performance of the tape and has high quality.

4. Set the base layer composed of soft plastic film layer, bonding glue layer and hard plastic film layer, which is firm and stable, reduces the impact on the environment, and is green and environmentally friendly.
