Abstract

The invention relates to the technical field of UV curing adhesive tapes, and in particular relates to an antistatic UV curing high-initial-adhesion re-stripping adhesive tape and a preparation methodthereof. The antistatic UV curing high-initial-adhesion re-stripping adhesive tape comprises an antistatic base film, an antistatic UV viscosity-reducing adhesive layer and an antistatic release filmwhich are arranged in sequence, wherein the antistatic UV viscosity-reducing adhesive layer is prepared from the following raw materials in parts by weight: 100 parts of an acrylate pressure-sensitive adhesive, 20-80 parts of a UV prepolymer, 0.5-5 parts of a curing agent, 0.2-5 parts of a photoinitiator, 0-5 parts of an antistatic agent, and 0-100 parts of a solvent. The antistatic UV curing high-initial-adhesion re-stripping adhesive tape disclosed by the invention has larger initial stripping force, and the stripping force is sharply reduced after UV illumination; and at the same time, theantistatic UV curing high-initial-adhesion re-stripping adhesive tape has an antistatic effect, and solves the problems that a current UV viscosity-reducing adhesive tape cannot resist static electricity and has low initial adhesion.

Description

technical field [0001] The invention relates to the technical field of UV curable adhesive tapes, in particular to an antistatic UV curable high initial adhesion re-peelable adhesive tape and a preparation method thereof. Background technique [0002] UV curing and peeling tape is usually also called UV adhesive tape, which refers to a tape that has a high adhesive force under normal conditions, and the adhesive force drops sharply after being irradiated by UV light, so that it can be easily peeled off. This tape is often used as a protective tape during the processing of precision materials such as mobile phone screens, lithium batteries, magnetic heads, and semiconductor wafers. [0003] For example, in the process of magnetic head processing, when the magnetic sheet material is cut, in order to fix the magnetic sheet, the adhesive force of the tape needs to be as large as possible, which can prevent the small magnetic head from collapsing or damaging the cutter; after cut...
