Embodiment

[0027] A glue remover, comprising: a first solvent, a second solvent, a stripping agent, a corrosion inhibitor, and an active agent.

[0028] Wherein, the first solvent is one or more random ratio mixtures in n-bromopropane, methyl benzoate, phenyl acetate, dimethyl methylphosphonate; the second solvent is ether or / and acetone; stripping agent It is triethanolamine or / and water; the corrosion inhibitor is octadecylamine; the active agent is sodium alkylbenzene sulfonate or / and sodium stearate.

[0029] In the present invention, the specific composition and proportioning ratio of each substance are shown in Table 1, and the weight unit of each component in Table 1 is Kg.

[0030] Table 1

[0031]

[0032] After the various components are mixed in the present invention, the adhesive remover prepared by mixing is non-flammable and explosive, therefore, the present invention has non-flammable and explosive properties. At the same time, by using the finished products of Exampl...

Abstract

The invention relates to a glue removing agent and applications of the glue removing agent in rail transit vehicle window maintenance, wherein the glue removing agent comprises the following raw materials by weight: 20-60 parts of a first solvent and 15-40 parts of a second solvent, wherein the first solvent is a mixture comprising one or a plurality of materials selected from n-bromopropane, methyl benzoate, phenyl acetate and dimethyl methylphosphonate according to any ratio, and the second solvent is diethyl ether or / and acetone. According to the invention, the glue removing agent has advantages of in-situ glue removing, strong permeability, low flammability, low explosiveness, high glue removing speed and the like, can thoroughly remove various colloids, glue stains, deposited carbon,lubricating greases, paints, rust, coating materials and oil dirt, does not cause corrosion, damage and black ash on the metal surface, is suitable for in-situ rapid glue removal operation of rail transit vehicles, and is greatly helpful for improving the efficiency of the maintenance process.

Description

technical field [0001] The invention relates to the field of glue remover, in particular to a glue remover and the application of the glue remover in the maintenance of rail transit vehicle windows. Background technique [0002] The vigorous development of the rail transit industry has put forward higher requirements for the safety, comfort and overall airtightness of train carriages. The bonded structure has the advantages of reducing vibration, absorbing moderate deformation, and reducing noise. In this context, the connection method of rail vehicle windows has gradually changed from the original mechanical structure connection to the colloidal adhesive connection method. [0003] The application areas of adhesives in the field of rail transit mainly include: ① elastic bonding of vehicle floors, roofs, side wall panels, etc.; Structural bonding of the shock-absorbing seat on the floor, the reinforcing rib of the wall panel roof, and the floor cloth; ④The stainless steel ...
