Abstract

The invention discloses a copolymer-modified PET adhesive tape, and relates to the technical field of tapes. The copolymer-modified PET adhesive tape comprises an adhesive-tape base material and an adhesive. The prepared copolymer-modified PET adhesive tape can adapt to the more-complex environment; the adhesive is a high-viscosity adhesive with the good wettability, urea hydrogen peroxide is added and used for modifying guar, uncovering and binding can be repeatedly carried out, and the adhesive residue trace problem can be solved.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to a copolymer modified PET adhesive tape. Background technique [0002] Filed in the United Kingdom and the United States on May 30, 1928, Drew developed a very light, one-press adhesive, which was later improved to create scotch tape. Why tape can stick things, of course, is because it has a layer of adhesive on its surface! The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together. [0003] The existing adhesive tapes not only have general aging resistance, but also have general bonding strength of the adhesive, which limits their application. Contents of the inv...
