Problems solved by technology

[0003] The tape is usually exposed to the air during use, and it is easy to reduce the performance of the adhesive layer of the tape under the action of dirt, water vapor or external force, or affect its bonding performance, which greatly reduces the service life of the tape
The ordinary tapes on the market today cannot take into account both adhesion and stability, and further research and development is needed
[0004] Some of the existing medical tapes on the market usually have poor viscosity, poor water resistance and aging resistance. Rising cost of treatment

Abstract

The invention discloses an electrostatic adsorption adhesive tape which comprises a protective layer, wherein an adhesive region located in the middle is arranged on the side surface of one side of the protective layer; protection regions are respectively arranged on two sides of the adhesive region; an adhesive layer made of an adhesive is arranged in the adhesive region; smooth electrostatic adsorption surfaces are arranged in the protective regions. The invention further discloses a preparation method of the electrostatic adsorption adhesive tape. The preparation method comprises the following steps: (a) preparation of an adhesive material: respectively covering the two sides of the adhesive material with release paper; (b) primary slitting or slicing; (c) compounding: compounding multiple long-strip type adhesive materials obtained by cutting on the electrostatic adsorption surfaces of the protective layer, and reserving a gap between two adjacent adhesive material strips, whereinthe width of each gap is twice the set width of each protective region; or compounding the sliced adhesive materials on the adhesive region of the protective layer in an arraying manner, and reservinga gap between two adjacent adhesive material slices, wherein the width of each gap is twice the set width of each protective region; (d) secondary slitting; (e) winding or stacking.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to an electrostatic adsorption adhesive tape and a preparation method thereof. Background technique [0002] Scotch tape was invented by Richard Drew in St. Paul, Minnesota, USA in 1928. Adhesive tapes can be divided into high temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure sensitive tapes and die-cut tapes according to their functions. Different functions can meet different industry requirements. A layer of adhesive is coated on the surface of the tape to make the tape stick to the object. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of the adhesive; in modern times, various polymers are widely used. [0003] The tape is usually exposed to the air during use, and it is easy to reduce the performance of the adhesive layer of the tape under the action of dirt, water vapor or external f...
