Abstract

The invention provides a neutral cleaning agent for motor trains and a preparation method thereof. The neutral cleaning agent for motor trains consists of the following components by weight: 4 to 6 parts by weight of anionic surfactants, 8 parts by weight of nonionic surfactants 12 parts by weight, 6 parts by weight to 10 parts by weight of complexing agent, 0.5 parts by weight to 2 parts by weight of dispersant, 3 parts by weight to 8 parts by weight of pH regulator, 62 parts by weight to 78.5 parts by weight of deionized water, Anionic surfactants include alcohol ether carboxylate AEC and fatty acid methyl ester sulfonate, and complexing agents include sodium iminodisuccinate and trisodium methylglycine diacetate. The EMU neutral cleaning agent can effectively remove yellow spots, water marks, dust and oil stains on the outer surface of the high-speed rail, and solve the problems of corroding the car body, polluting the environment, and endangering health in the cleaning process of existing cleaning agents.

Description

technical field [0001] The invention relates to rail transit vehicle maintenance technology, in particular to a cleaning agent for daily maintenance of high-speed rail, in particular to a neutral cleaning agent for EMUs and a preparation method thereof. Background technique [0002] With the continuous development of economy and society, rail transit has become the main means of transportation in today's society (such as: EMU trains, subways, light rails, magnetic levitation, high-speed rail, etc.), and the outer surface of the train body is easily polluted during operation. Factors such as dust in the air, carbon powder and iron filings produced by electric arcs and wheel-rail friction, rusty water falling from iron bridges or iron frames, insects and their excrement, and oxidation caused by long-term contact with air on the surface of the car body, etc. Due to the influence of various kinds of dirt combined to form mixed dirt, the surface pollution of the car body usually ...
