Preparation and adhesion performance of transparent acrylic pressure-sensitive adhesives containing menthyl acrylate

摘要

Using the synthesized menthyl acrylate derived from the menthol as biomass, transparent acrylic pressure-sensitive adhesives (PSAs) composed of semi-interpenetrated structured polymer networks were prepared successfully. The effect of menthyl acrylate concentration in the PSAs was investigated on adhesion performances of the acrylic PSAs. The prepared syrups for acrylic PSAs were characterized and the optical properties for their acrylic PSA films were also examined by UV-Vis spectroscopy, haze meter and prism coupler. The acrylic PSAs exhibited high transparency in the visible wavelength region regardless of reliability test (85/85 test). With increasing menthyl acrylate concentration in the acrylic PSAs, adhesion performances such as the peel strength, cohesion strength, and probe tack were increased.
