Abstract

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.

Description

technical field [0001] The invention relates to the field of acrylate structural adhesives, in particular to an acrylate adhesive used for bonding a reinforcing rib of a motor vehicle roof panel. Background technique [0002] When the vehicle of the high-speed EMU is running, its parts and components are in a state of high-frequency vibration for a long time. In order to ensure safety, the fatigue resistance of the parts has become a key factor in quality inspection. The middle roof is the top assembly part of the high-speed EMU. The area is large, and a large number of reinforcing ribs need to be used to reinforce the middle roof to increase the fatigue resistance of the middle roof. In actual installation, the reinforcing ribs and the middle roof are usually fixed by practical adhesive. [0003] However, the existing viscose is usually used in a relatively fixed environment. When it is in a high-frequency vibration state, the viscose is prone to detachment, which is danger...
