  • Method of preparing elastic pressure-sensitive adhesive tape and elastic pressure-sensitive adhesive tape
    Patent number: 11597857
    Abstract: Disclosed are a method of preparing an elastic pressure-sensitive adhesive tape and an elastic pressure-sensitive adhesive tape. Main components of the adhesive include a polyacrylate resin with a carbon-carbon double bond and a diluent monomer with a carbon-carbon double bond. A quasi-microcapsule powder component is adopted, wherein the shell material of the quasi-microcapsule powder selects a cellulose-based water soluble polymer, and the core material selects low boiling point alkane, wherein the preparation method combines UV curing, heating, and shell burst, to obtain an elastic adhesive layer, whereby to prepare a pressure-sensitive adhesive tape product. Compared with conventional elastic pressure-sensitive adhesive tapes, the preparing method as disclosed has a simple manufacturing process.
