Problems solved by technology

[0003] At present, the neutral cleaning agents used on the outer surface of trains on the market will not cause damage to the paint on the surface of the car body and the base material of the car body, but the cleaning effect cannot meet the requirements and the cleaning speed is slow
And acidic or alkaline cleaning agents, although cleaning has a certain effect, these cleaning agents also cause damage to the train surface paint and car body substrate while cleaning.
And most cleaning agents have phosphate contamination

Embodiment 1

[0020] Each component is selected according to the following mass percentages: 10-15% of compound organic chelating agent, 35-45% of surfactant, 5-8% of corrosion inhibitor, 8-14% of cleaning aid, 3-5% of absolute ethanol, The balance is deionized water, and the corrosion inhibitor is composed of urotropine, sodium metasilicate pentahydrate and benzotriazole according to the mass-number ratio of 13-17:28-32:53-57; In the agitator, first dissolve the benzotriazole with absolute ethanol to obtain the absolute ethanol and benzotriazole solution for use, then add the compound organic chelating agent in deionized water at 35-40°C, and stir until After fully dissolved, add cleaning aid, absolute ethanol and benzotriazole solution, urotropine and sodium metasilicate pentahydrate in sequence, stir until completely dissolved, then add surfactant, continue stirring until the solution is completely dissolved into a uniform Transparent liquid, finally sealed and packaged, waterproof and m...

Embodiment 2

[0035] According to the preparation method of Example 1, take the train environmental protection high-efficiency cleaning agent aqueous solution prepared by the formula number 6, dilute it to 5% concentration, clean the test piece with a small ultrasonic cleaning machine for 5 minutes, and test the effect of different temperatures on the cleaning efficiency Influence, the results are shown in Table 2:

[0036]

[0037] Table 3 Comparison Table of Cleaning Efficiency Effects of Different Temperatures

[0038] The results show that the cleaning efficiency is better when the cleaning temperature is above 20°C, and the cleaning efficiency does not change above 30°C, so it is generally better to choose a temperature of 35°C for cleaning.

Embodiment 3

[0040] According to the preparation method of Example 1, take the train environmental protection and high-efficiency cleaning agent aqueous solution prepared by the formula number 6, dilute to different concentrations at 35 ° C, and clean the test piece with a small ultrasonic cleaner for 5 minutes to test the effect of different concentrations on cleaning efficiency , the results are shown in Table 3:

[0041]

[0042] Table 4 Comparison Table of Cleaning Efficiency Effects of Different Concentrations

[0043] The results show that the cleaning efficiency is better when it is diluted to a concentration of 5% to 6%. Considering the cleaning cost, 5% is the best dilution concentration.

Abstract

The invention provides an environment-friendly efficient train cleaning agent. The cleaning agent is formed by, by weight, 10% to 15% of compound organic chelating agents, 35% to 45% of surface active agents, 5% to 8% of corrosion inhibitors, 8% to 14% of cleaning auxiliaries, 3% to 5% of anhydrous ethanol, and the balance deionized water, wherein the corrosion inhibitors are formed by, by mass fraction, 13-17 parts of urotropine, 28-32 parts of sodium metasilicate pentahydrate and 53-57 parts of benzotriazole. The invention further provides a preparation method of the cleaning agent. The surface of a train body is not damaged by the environment-friendly efficient train cleaning agent, meanwhile, cleaning efficiency is high, the dilution ratio is high, the cleaning agent can be diluted by 20-30 folds through tap water when used normally, and using cost is reduced.

Description

technical field [0001] The invention relates to an environmentally friendly and efficient cleaning agent for trains and a preparation method thereof, belonging to the field of chemical cleaning agent preparation. Background technique [0002] With the continuous development of the economy and society, rail transit trains have become the main means of transportation in today's society, such as the cleaning of the outer surface of vehicles and the cleaning of vehicle interior panels for various EMU trains, subway (including light rail) trains, and maglev trains. During the operation of the train, the outer surface of the car body is extremely susceptible to pollution, such as animal organisms, sand and dust brought up by the train during operation, carbon powder and metal ions, oxides, avian blood stain protein, Due to the influence of time factors such as oil stains, various dirts are often combined to form mixed dirt. The surface pollution of the car body usually manifests a...
