Description

A kind of train environment-friendly high-efficiency abluent and preparation method thereof

Technical field

The present invention relates to a kind of train environment-friendly high-efficiency abluent and preparation method thereof, belong to chemical preparation field.

Background technology

Along with the development of economic society, rail transit train has become the main traffic instrument of society, as various Motor train unit train, subway (containing light rail) train, the vehicle external surface of magnetic suspension train clean and the cleaning of vehicle interior trim panel Deng, train outer surface of car body in running is highly prone to pollute, and such as animal organisms, takes up during train operation Sand dust, carbon dust that pantograph and wheel-rail friction produce and metal ion, oxide, birds bloodstain albumen, greasy dirt etc. because of time Between the multiple dirt of impact of factor be often combined together to form mixed dirt, car body surface pollutes and is usually expressed as overall change Huang, locally macula lutea and strip current mark etc.；Clean and difficulty.

In the market for the neutral cleaners of train outer surface, although car body surface paint, car body base material will not be made Becoming damage, but cleaning performance does not reaches requirement, cleaning speed is slow.And acid or alkaline cleaner, although clean and have necessarily Effect, but these abluents also result in damage to Train surface paint, car body base material while cleaning.And major part All there is phosphate contamination in abluent.

Summary of the invention

In order to solve the deficiencies in the prior art, the invention provides a kind of train environment-friendly high-efficiency abluent and preparation method thereof, Abluent is to car body surface not damaged, and cleaning speed is fast, effective simultaneously, and concentrating degree is high, fully makes after dilution With can be cost-effective.

The present invention solves that its technical problem be the technical scheme is that and provide a kind of train environment-friendly high-efficiency abluent, Composed of the following components, the percentage by weight of each component is: compound organic sequestering agent 10～15%, surfactant 35～ 45%, corrosion inhibiter 5～8%, cleaning additive 8～14%, dehydrated alcohol 3～5%, surplus is deionized water；Described slow Erosion agent by hexamethylenamine, metasilicate pentahydrate sodium and BTA according to mass ratio 13～17:28～32:53～57 groups Become.

Described compound organic sequestering agent by potassium citrate, disodiumedetate, sodium gluconate, sulfamic acid sodium, Polyacrylic acid and sodium polyacrylate are according to mass ratio 10～14:8～12:33～37:16～20:8～12:13～17 Composition.

Described surfactant by dodecylbenzene sodium sulfonate, dispersant NP-10, cleanser 105, penetrating agent JFC, And emulsifier op-10 and OP-7 according to mass ratio 28～32:4～6:23～27:8～12:13～17:13～ 17 compositions.

Described cleaning additive is a kind in sodium carbonate, sodium sulfate or ammonium chloride.

Invention also provides the preparation method of this train environment-friendly high-efficiency abluent, choose each group by following mass percent Point: compound organic sequestering agent 10～15%, surfactant 35～45%, corrosion inhibiter 5～8%, cleaning additive 8～14%, Dehydrated alcohol 3～5%, surplus is deionized water, and described corrosion inhibiter is by hexamethylenamine, metasilicate pentahydrate sodium and benzo three nitrogen Azoles forms according to mass ratio 13～17:28～32:53～57；In rustless steel agitator, first with dehydrated alcohol by benzene And triazole dissolves and obtains dehydrated alcohol and BTA solution for later use, after under 35～40 DEG C of environment in deionized water Add compound organic sequestering agent, be sequentially added into cleaning additive, dehydrated alcohol after stirring to fully dissolving molten with BTA Liquid, hexamethylenamine and metasilicate pentahydrate sodium, stir and add surfactant after all dissolving, and continues stirring until solution Being completely dissolved into homogeneous transparent shape liquid, finally sealed is packed, waterproof and dampproof in packaging process.

The present invention is had advantageous effect in that based on its technical scheme:

(1) the train environment-friendly high-efficiency abluent of the present invention is water preparation, soluble in water, mechanical cleaning after suitable dilute with water Or manually clean Train surface, and it is easy and fast to rinsing；

(2) the compound organic sequestering agent in the present invention is combined organic sequestering agent by disodiumedetate, gluconic acid Sodium, sulfamic acid sodium, polyacrylic acid, sodium polyacrylate and potassium citrate composition, these components are the most soluble in water, to row Car epidermis solids foul, greasy dirt have strong hydrotropy effect, strengthen the dissolving dynamics to these dirts, make Train surface difficult The solids foul being dissolved in water is quickly dissolved in water, reaches the effect of high-efficiency washing, and this compound organic sequestering agent overcomes biography completely System abluent relies on Phosphonate chelating agent, it is to avoid environmental pollution, and more efficient；

(3) surfactant in the present invention by dodecylbenzene sodium sulfonate, dispersant NP-10, cleanser 105, Penetrating agent JFC and emulsifier op-10 and OP-7 form, and form oleophylic and hydrophilic group, lipophilic group in water There is extremely strong lipophile, it is possible to absorption oils and fats makes greasy dirt peel off Train surface, and hydrophilic group then has extremely strong hydrophilic, Greasy dirt is made to be quickly dissolved in water；Surfactant can reduce the surface tension of water, and improves the solubility of organic compound, Reach to deoil, decontamination purpose；

(4) corrosion inhibiter is made up of hexamethylenamine, metasilicate pentahydrate sodium, BTA, can promote hard in use Water softens, and regulates and stablize pH value, improves surfactant properties, largely effective prevent non-ferrous metal and paints variable color, Protection train railway carriage is not cleaned by the acidity in agent or alkaline components corrosion, thus plays protection train epidermis when cleaning Effect；But the phenylpropyl alcohol in corrosion inhibiter triazole itself are water insoluble, therefore add dehydrated alcohol, make phenylpropyl alcohol three Nitrogen azoles is dissolved in dehydrated alcohol, is more effectively and rapidly dissolved in water so that whole train environment-friendly high-efficiency abluent becomes water preparation；

(5) cleaning additive selects sodium carbonate, sodium sulfate or ammonium chloride, itself does not has obvious washability, but joins at this The washing dirt-removing power of compound organic sequestering agent and surfactant can be improved after side adds, thus effectively facilitate water The wash degree of solution；

(6) the train environment-friendly high-efficiency abluent extension rate of the present invention is high, can dilute with tap water during normal use 20～30 times, reduce use cost；

(7) the train epidermis cleannes that the train environment-friendly high-efficiency abluent of the present invention is cleaned are high, and epidermis is dried without appointing What vestige, will not corrode motor-car crust paint and metal parts.

Detailed description of the invention

Below in conjunction with embodiment, the invention will be further described.
