Research on the preparation and adhesion properties of high-performance pressure sensitive adhesive
Methyl acrylate(MA),butyl acrylate(BA)were employed respectively as hard and soft mono-mers,hydroxyethyl acrylate(HEA)/vinyl acetate(VAc)and acrylic acid(AA)were chosen as crosslinked monomers to prepare two solvent-type polyacrylate-based pressure-sensitive adhesives(PSA-1 and PSA-2)via a solution polymerization.The influence of tackifying resin and silane coupling agent on the bonding strength of pressure-sensitive adhesive was studied.The results showed that the PSA modified with 7％polyvinylpyrrolidone(PVP K30)and 5％silane coupling agent(KH550),the shear strength and peel strength could reach 1.65 MPa and 2.97 kN/m,as well as a good heat resistance.
