The invention discloses an acrylate adhesive for bonding bullet train roof reinforcing ribs, and relates to the field of acrylate structure adhesives. The acrylate adhesive comprises, by volume, 1 part of oxidizing agents and 7-15 parts of reducing agents. The oxidizing agent comprises, by weight, 30-50 parts of dibutyl phthalate, 1-5 parts of bisphenol-A-type epoxy resin, 15-20 parts of high-glue powder, 10-20 parts of benzoyl peroxide and 1-5 parts of castor oil. The reducing agents comprise, by weight, 20-54 parts of methyl methacrylate, 10-20 parts of impact modifiers, 10-15 parts of chlorosulfonated polyethylene, 1-3 parts of triethylene diamine, 0.5-1 part of paraffin, 1-5 parts of acrylic acid, 0.3-1 part of stabilizing agents and 1.2-1.6 parts of organic modified bentonite. The acrylate adhesive can be closely connected with bonding materials in high-frequency vibrating states and cannot peel when being used for a long time.
