Abstract

The invention belongs to the field of fine chemical engineering, and relates to a decontamination and rust prevention two-in-one cleaning agent. The decontamination and rust prevention two-in-one cleaning agent is prepared from sodium hydroxide, an anionic surfactant, a non-ionic surfactant, a low-foam efficient amphoteric solubilizer, a decontamination synergist, sodium nitrite and zero-water sodium metasilicate. According to the decontamination and rust prevention two-in-one cleaning agent, the sodium hydroxide serves as a strong-basicity solvent, and thus the oil contamination removing ability of the cleaning agent is higher; the alkali-proof surfactants are selected and can exert the respective functions under the alkaline environment, wherein particulate matters can be well removed byusing the polarity of the anionic surfactant, and oil stain can be better removed through the non-ionic surfactant; by adding the efficient solubilizer and the decontamination synergist, it can be ensured that a cleaning agent solution is clear and not chaotic, the using amounts of the anionic surfactant and the non-ionic surfactant can be decreased, and thus the cost is reduced; and the sodium nitrite and the zero-water sodium metasilicate act on the surface of a metal bogie synergistically, and thus the cleaned bogie is prevented from rusting.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and relates to a decontamination and antirust two-in-one cleaning agent, which is suitable for railway vehicle bogie equipment. Background technique [0002] Railway vehicles generally need to overhaul and maintain important parts such as railway vehicle bogies after running for a certain mileage (for example, the EMU requires 1.2 million kilometers), and before the maintenance, the railway vehicle bogies need to be cleaned as a whole to remove other components. All kinds of dirt adhered during operation, and it is also necessary to ensure that the bogie cannot be rusted after cleaning, so as to facilitate the next step of decomposition operation and ensure the quality of maintenance. [0003] Based on the fact that the train has been exposed to harsh environments such as wind, sand, salt spray, and heat and humidity all year round, for the dirt adhered to the bogie and other parts, it is judged tha...
