Abstract
The invention discloses a solvent type acrylic pressure sensitive adhesive and a preparation method thereof. The solvent type acrylic pressure sensitive adhesive of the formula is prepared from, by weight, 1-3% of acrylic acid, 0.5-8% of hydroxyethyl acrylate, 0.5-8% of hydroxy-propyl acrylate, 0.5-8% of hydroxy-butyl acrylate, 24-71% of iso-cctyl acrylate, 20-71% of butyl acrylate, 20-70% of solvents and 1-4%o of initiators. An ethyl acetate, acetone and toluene mixed system is adopted for the solvent, and ethyl acetate, acetone and toluene are mixed according to the proportion of 9:0.5:0.5. The initiators are prepared from azodiisobutyronitrile and bis(4-tert-butylcyclohexyl)peroxydicarbonate. The acrylic adhesive for PE protective films is provided, and the protective films are mainly used for protecting screens in the mobile phone producing process. The adhesive has good adhesive force on base materials and meanwhile well solves the 'ghost' problem.
