Problems solved by technology

The pH value of this cleaning agent for the outer surface of high-speed rail is close to 7, which solves the problem that the existing cleaning agent is easy to damage the paint and rubber on the outer surface of the high-speed rail, and the waste water generated by use seriously pollutes the environment, and the cleaning rate is as high as 93%.

Embodiment 1

[0014] In parts by weight, 10 parts of γ-glycidyl etheroxypropyltrimethoxysilane was added to 50 parts of deionized water, and stirred at room temperature for 24 hours to obtain a uniform and transparent epoxy-based silica nanoparticle hydrosol, Standby; mix 2 parts of sodium chloride, 2 parts of calcium laurate, 3 parts of sodium pyrrolidone carboxylate, 2 parts of 2,4-dihydroxybenzophenone and 15 parts of glycerin and stir at 50 ° C for 0.5 hours; then at 50 Add 20 parts of epoxy-based silicon dioxide nanoparticle hydrosol and 22 parts of deionized water to the above mixture at ℃, stir evenly, and then cool to obtain the high-speed rail train casing protection liquid.

[0015] The surface of the cleaned high-speed train is evenly sprayed with the high-speed train shell protective liquid prepared in this embodiment. After 10 hours of high-speed train operation, there is only a small amount of oil and dust attached to the surface of the shell, no yellow spots, and no stubborn ...

Embodiment 2

[0017] In parts by weight, 10 parts of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane was added to 50 parts of deionized water, and stirred at room temperature for 24 hours to obtain a uniform and transparent epoxy dioxide Silicon nanoparticle hydrosol, spare; mix 5 parts of sodium chloride, 1 part of calcium laurate, 1 part of sodium pyrrolidone carboxylate, 3 parts of 2,4-dihydroxybenzophenone and 11 parts of glycerin and stir at 50 °C 0.5 hours; then add 15 parts of epoxy-based silicon dioxide nanoparticle hydrosol and 25 parts of deionized water to the above mixture at 50° C., stir evenly and then cool to obtain the high-speed rail train casing protection liquid.

[0018] The cleaning condition of the high-speed train is the same as in Example 1. The surface of the cleaned high-speed train is evenly sprayed with the high-speed train shell protective liquid prepared in this embodiment. After 10 hours of high-speed train operation, there is only a small amount of oil and dust...

Abstract

The invention belongs to the field of high-speed rail train cleaning and protection, and relates to a high-speed rail train shell protective liquid. Raw materials include, by weight, 2 to 5 parts of sodium chloride, 1 to 3 parts of calcium laurate, 1 to 4 parts of sodium pyrrolidone carboxylate, 15 to 25 parts of epoxy silicon dioxide nanoparticle hydrosol, 2 to 3 parts of 2,4-dihydroxy benzophenone, 10 to 15 parts of glycerol and 20 to 25 parts of deionized water. The protective liquid can still be firmly adsorbed on the surface of a shell of the high-speed rail train when the high-speed railtrain runs at a high speed, forms an anti-pollution superfine micro-nano structure, and can effectively suppress adsorption and adhesion of pollutants on the surface of the shell of the high-speed rail train; the high-speed rail train can be cleaned more easily, the cleaning time is shortened, the use amount of a cleaning agent is reduced, and the protective liquid has the advantages of being efficient in protection, long in action period, convenient to use and low in cost and has remarkable market prospects.

Description

technical field [0001] The invention belongs to the field of cleaning and protection of high-speed rail trains, and in particular relates to a high-speed rail train shell protective liquid. Background technique [0002] High-speed rail trains are fast, comfortable, stable, safe, energy-saving and environmentally friendly, and are very popular among contemporary people. All countries in the world strongly support the use of new high-speed rail trains to meet the growing travel needs. The running speed of the high-speed rail is very fast. During the operation of the high-speed rail, the outer surface of the train is prone to generate static electricity and absorb dust. In addition, due to weather and other reasons, it will also cause dust accumulation and rust spots on the car body. Although high-speed rail trains are cleaned regularly, certain adsorbents are difficult to clean, and a large number of yellow spots and stubborn dirt will appear on the shell of high-speed rail t...
