Problems solved by technology

The acidic cleaners currently used for locomotive cleaning have good decontamination performance, but they are more corrosive to aluminum alloys and have a strong corrosion effect on aluminum alloy parts of motor vehicles, which reduces the service life of these parts of motor vehicles
At the same time, the strong acidic car wash liquid is directly discharged without any treatment, which also causes certain pollution to the environment.

Abstract

The invention discloses a motor train outer wagon acid liquid-state cleaning agent composition, which consists of organic base, organic acid, corrosion inhibitors, nonionic surfactants, anion surfactants and water. A preparation method of the cleaning agent composition comprises the following steps that: the water is heated to 40 to 60 DEG C in a stirring pot, during the stirring, the organic base, the organic acid, the corrosion inhibitors, the nonionic surfactants and the anion surfactants are sequentially added into the water in the stirring pot to be uniformly stirred and mixed, the heating is stopped after all raw materials are melted, the materials are continuously stirred for 20 to 100 minutes, a system is uniformly mixed, and a motor train outer wagon acid liquid-state cleaning agent disclosed by the invention is obtained. During the application, the motor train outer wagon acid liquid-state cleaning agent is diluted by water according to a volume ratio of the motor train outer wagon acid liquid-state cleaning agent to water of 1:(5-20), and the motor train outer wagon acid liquid-state cleaning agent can be used.

Description

technical field [0001] The invention relates to a cleaning agent for locomotive outer wagons in railway system, more specifically relates to an acidic liquid cleaning agent for outer wagons of motor vehicles. Background technique [0002] During the fast running of the train, the dirt on the outer wagon is mainly composed of: 1) slightly acidic organisms such as bird excrement and insects; 2) dust, clay, and fine carbon powder, iron powder, Metal ions or metal oxide solids, 3) oily oil stains, 4) other various mixed dirt and rust spots formed. These dirt stay on the outer surface of the pure white EMU, which is particularly sensitive to pollution and coloring. If it is not washed and removed in time, it will accelerate its yellowing and lose the luster of the paint film. However, if detergents are used randomly, even though the motor car body is sprayed with a polyurethane topcoat with good gloss and color retention, it may also cause accelerated aging or even yellowing of ...
