Modified polyacrylate pressure-sensitive adhesive for folding adhesive tape and preparation method of modified polyacrylate pressure-sensitive adhesive

The invention discloses a modified polyacrylate pressure-sensitive adhesive for a folding adhesive tape and a preparation method of the modified polyacrylate pressure-sensitive adhesive. The adhesive is prepared from the following raw material components in parts by mass: 15 to 25 parts of n-butyl acrylate, 5 to 10 parts of 2-ethylhexyl acrylate, 2 to 6 parts of acrylic acid, 3 to 8 parts of methoxy polyethylene glycol 400 acrylate, 1 to 5 parts of a modified monomer A, 0.5 to 4 parts of a modified monomer B, 0.1 to 1.1 parts of an initiator, 5 to 10 parts of tackifying resin and 40 to 75 parts of a solvent. According to the modified polyacrylate pressure-sensitive adhesive for the folding adhesive tape, a soft monomer is taken as a main monomer, and a long-chain low-glass-transition-temperature monomer and a special modified monomer are introduced, so that the prepared polyacrylate pressure-sensitive adhesive has low temperature, low modulus and excellent bonding performance on different bonded interfaces. 本
