Description

Train outside compartment cleaning agent and preparation method thereof

Technical Field

The invention belongs to the technical field of chemical cleaning agents, and particularly relates to a train outside compartment cleaning agent and a preparation method thereof.

Background

The locomotive outer carriage is used as an important component, along with the vigorous development of urban construction, the requirement on the appearance of the locomotive is higher and higher, and because the locomotive is exposed in the air for a long time and is influenced by adverse factors such as ultraviolet irradiation, rain wash, sand erosion and the like, the brightness and the thickness of the locomotive paint surface are greatly reduced, so that the locomotive paint surface is gradually whitened, blackened and lackluster, an oxide layer is further formed, and the service life of the locomotive is shortened. In addition, the locomotive generates a strong electrostatic layer due to air friction during running, and adsorbs a large amount of dust, oil stain and chemical dust, and a hard traffic film is formed after a long time. If the traffic film cannot be removed in time, the paint surface of the locomotive is easy to oxidize, corrode and peel off. Along with the rapid development of the rail transit industry, the number of running trains is greatly increased, the use amount of products for cleaning and maintaining the outside of the train is also greatly increased, and the market demand is huge. Therefore, the development of a high-quality and high-efficiency cleaning agent product for cleaning and maintaining the appearance of the locomotive is urgently needed.

Through searching, the following two patent publications related to the patent application of the invention are found:

1. the high-efficiency cleaning agent for the hard scale on the surface of the high-speed train, the preparation method and the cleaning method (CN106675879A) comprise the following raw material components in percentage by mass: 0.1-10% of nonionic surfactant, 0.1-5% of essential oil, 0.1-20% of oxygenated solvent, 0.5-15% of alcohol solvent and 50-90% of water. The preparation method comprises the following steps in sequence: a. adding water into a stirring kettle, adding the nonionic surfactant, the oxygen-containing solvent and the alcohol solvent, mixing and stirring uniformly; b. adding the essential oil, and uniformly stirring; the cleaning method comprises machine cleaning or manual cleaning, wherein the machine cleaning is used in a general cleaning machine for trains, 8#10 sections are grouped, the using amount is 5#8 kilograms, and the machine cleaning is used at normal temperature; the manual cleaning is to use tap water to prepare about 5 percent of cleaning solution and use rag, brush or mop to dip the cleaning solution to scrub the surface of the train.

2. The train surface oil stain cleaning agent (CN103436392A) comprises the following components in percentage by mass: 16-19% of eicosane, 7-9% of limonene, 55-65% of decafluoropentane, 6-8% of N-methylpyrrolidone, 3-6% of ethylene glycol monobutyl ether, 0.8-2.6% of NP-8.6, 0.5-1.5% of benzotriazole and 0.5-1.5% of JFC. The cleaning agent is suitable for cleaning various maintenance mark stroke lines of various rail transit trains, sealing paint and oil stains on the surfaces of various hubs, and surface oil stains such as solidified stains on the surfaces of mechanical parts of the hubs, and the like, can not cause damage to the surfaces of train bodies and the mechanical parts of the trains, does not damage human bodies, and has no pollution to the environment.

By contrast, the present patent application is substantially different from the above patent publications.
