Problems solved by technology

Since the bottom plate of the motor car is close to the ground, it is easily eroded by water vapor, and when the motor car is running, it will pass through areas with large temperature differences, so that the baseboard and viscose are not only in a state of slight vibration for a long time, but also prone to thermal expansion and cold shrink
[0004] Existing adhesives are easy to peel off when used in a humid environment, and the volume changes greatly during curing, and more heat is released, which is easy to cause corrugated burns on the skirting board, resulting in deformation of the board

Abstract

The invention discloses an acrylate adhesive for cementing a skirting line of ahigh-speed train, relating to the field of acrylate structural adhesives. The acrylate adhesive contains the following components in parts by volume: 1 part of an oxidizing agent and 8-12 parts of a reducing agent, wherein the oxidizing agent contains the following components in parts by weight: 10-45 parts of dibutyl phthalate, 0-5parts of bisphenol A epoxy resin, 1-5 parts of a silane coupling agent, 10-20 parts of calcium carbonate, 15-20 parts of benzoyl peroxide and 1-5 parts of castor oil; the reducing agent contains the following components in parts by weight: 20-45 parts of methyl methacrylate, 5-20 parts of an impact-resistant modifier, 5-10 parts of chlorosulfonated polyethylene, 1-3 parts of an accelerant, 0.5-1 part of paraffin, 2-5 parts of maleic acid, 0.5-1 part of a stabilizer, 5-10 parts of calcium carbonate and 1-5 parts of the silane coupling agent. The acrylate adhesive has relatively good heat resistance and moisture resistance, the volume change is relatively small during the curing, and a high exothermic peak is avoided.

Description

technical field [0001] The invention relates to the field of acrylic structural adhesives, in particular to an acrylic adhesive used for bonding motor vehicle skirtings. Background technique [0002] In the compartments, cabs and toilets of high-speed trains, in order to increase the impact resistance of the wall area and improve the combination of the wall and the floor, it is necessary to set a skirting line at the connection between the wall and the floor. [0003] Most of the baseboards are made of wooden thin-layer boards. During construction, the baseboards are mainly bonded to the wall by sizing the entire area. Since the bottom plate of the motor car is close to the ground, it is easily eroded by water vapor, and when the motor car is running, it will pass through areas with large temperature differences, so that the baseboard and viscose are not only in a state of slight vibration for a long time, but also prone to thermal expansion and cold shrink. [0004] Exist...
