Abstract

The invention discloses an acrylic glue used for bonding the roof reinforcement rib of a motor vehicle, and relates to the field of acrylic structural glue. The acrylic glue includes 1 part of oxidizing agent and 7 to 15 parts of reducing agent in parts by volume; parts by mass, The oxidizing agent includes 30-50 parts of dibutyl phthalate, 1-5 parts of bisphenol A epoxy resin, 15-20 parts of high rubber powder, 10-20 parts of benzoyl peroxide and 1-5 parts of Castor oil; in parts by mass, the reducing agent includes 20 to 54 parts of methyl methacrylate, 10 to 20 parts of impact modifier, 10 to 15 parts of chlorosulfonated polyethylene, and 1 to 3 parts of triethylenediamine , 0.5-1 part of paraffin, 1-5 parts of acrylic acid, 0.3-1 part of stabilizer, 1.2-1.6 parts of organically modified bentonite. The acrylic glue of the present invention can be closely connected with the adhesive under high-frequency vibration state, and does not fall off after long-term use.

Description

technical field [0001] The invention relates to the field of acrylic structural adhesives, in particular to an acrylic adhesive used for bonding the reinforcing ribs of the roof plates of motor vehicles. Background technique [0002] When the high-speed EMU vehicles are running, their components are in a state of high-frequency vibration for a long time. In order to ensure safety, the fatigue resistance of the components becomes a key factor in quality inspection. The middle roof is the top assembly part of the high-speed EMU. Its use The area is very large, and it is necessary to use a large number of ribs to reinforce the middle roof to increase the fatigue resistance of the middle roof. In actual installation, the ribs are usually fixed to the middle roof with glue. [0003] However, the existing viscose is usually used in a relatively fixed environment. When it is in a state of high-frequency vibration, the viscose is prone to detachment, which is relatively dangerous. ...
