Detergent for yellow spots on outer surface of railway vehicle and preparation method and application of detergent

Abstract

The invention provides a detergent for yellow spots on the outer surface of a railway vehicle and a preparation method and application of the detergent. The detergent for the yellow spots on the outersurface of the railway vehicle consists of the following components in percentage by mass: 12-18.5% of a compounded surfactant, 15-20% of a chelating agent, 8-14% of a solubilizer, 5-8% of a builderand the balance of water, wherein the compounded surfactant consists of an anionic surfactant and a nonionic surfactant in a mass ratio of 1:(2-4); the chelating agent is selected from one or two of ethylenediamine tetraacetic acid tetrasodium salt and sodium iminodisuccinate in any ratio; the solubilizer is one or two of N,N-dimethyldecanamide and sodium isopropyl benzoate in any ratio; and the builder is selected from one or two of ethanol amine and potassium carbonate in any ratio. The detergent provided by the invention is good in dirt removing power, and particularly has a good removing capability for yellow spots on railway vehicles.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a cleaning agent for the outer surface of rail vehicles, a preparation method and application thereof. Background technique [0002] Rail vehicles, such as high-speed railway passenger cars and urban rail transit vehicles, run at high speeds and generate friction with the air, resulting in the separation of airflow and the formation of negative pressure, which makes the surface of the car body adhere to dust, clay, and iron filings and carbon powder produced by wheel-rail friction etc.; in summer and autumn, fast-moving trains collide with mosquitoes, flies and flying insects, and the broken bodies of flying insects leave various organic substances such as protein on the surface of the train, making the dirt composition of the car body more complicated. Yellow spots on the car body are typical stubborn dirt on rail vehicles. The accumulation of dirt will not ...

AI Technical Summary

Problems solved by technology

[0006] The dirt composition on the surface of rail vehicles is not only complex and uncertain, but also the dirt may be superimposed after a long period of high-speed airflow impact and air-drying process, which greatly increases the difficulty of cleaning

In addition, the diversity of train body materials (aluminum alloy coated with metallic paint and top paint, EPDM rubber and glass with polyurethane anti-glare and anti-reflection protective film), the limitation of cleaning time and the existing The characteristics of the cleaning process based on mechanical spraying and scrubbing pose greater challenges to the development and application of cleaning agents
