Abstract

The invention aims to provide a train head shellac detergent which is composed of the following components in percentage by mass: 5-15% of citric acid, 3-5% of sodium tripolyphosphate, 2-8% of fatty alcohol, 3-5% of alkyl sodium sulfonate, 5-10% of alkyl glycoside, 5-10% of nonylphenol polyethenoxy ether, 0.04-0.08% of defoaming agent and the balance of deionized water. The train head shellac detergent is suitable for cleaning the head surface of various rail traffic trains, is especially suitable for yellow spots, rust and other surface shellac and oil stains caused by gum, bird manure, insect carcase and washmarks attached to the windshield of the train head in the high-speed running process, can not damage the surfaces of the train body and train head, and is harmless to the human body and pollution-free for the environment.

Description

Train termination shellac clean-out system

technical field:

The present invention relates to a kind of clean-out system, particularly relate to a kind of train termination shellac clean-out system.

background technology:

Along with the development of economic society, train has become the main traffic instrument of society, as various motor train unit train, intercity track train, subway, magnetic suspension train etc., the outside surface of train termination of car body in operational process can be subject to various pollution unavoidably, the natural gum that windshield glass as train termination is stained with in high-speed cruising, birds droppings, and the insect bodies that insect shock windshield glass produces, the macula lutea that washmarking causes, rust stain all very easily pollutes train termination, particularly to the pollution of train windshield glass, very easily the driving of attendant is affected greatly.

Also be exclusively used in train cross cut end (of a beam) greasy dirt in the market, macula lutea, the clean-out system of rust stain, but existing common greasy dirt or other clean-out systems on use market, this clean-out system is difficult to the motor-car to rail transit train, subway (containing light rail) train, all kinds of greasy dirt cleanings of magnetic suspension train, the natural gum that windshield glass is stained with in high-speed cruising, birds droppings, and the insect bodies that insect shock windshield glass produces, the macula lutea that washmarking causes, rust stain pollutes etc. cleans, very easily damage is caused to the surface of the termination of car body and windshield when cleaning with the surface of existing clean-out system to train termination, and cleaning performance is not good.

summary of the invention:

The present invention will provide a kind of train termination shellac clean-out system exactly, it is suitable for the surface cleaning of the termination to various rail transit train, particularly the windshield glass of car termination be stained with in high-speed cruising natural gum, birds droppings, the surperficial shellac such as macula lutea, rust stain that insect bodies, washmarking cause, greasy dirt spot cleaning, can not damage the surface of train body, train head, to human zero damage, environmentally safe.

A kind of train termination of the present invention shellac clean-out system, comprises following masses and forms than component:

Citric acid 5-15%,

Tripoly phosphate sodium STPP 3-5%,

Fatty alcohol-polyoxyethylene ether 2-8%,

Alkyl sodium sulfonate 3-5%,

Alkyl glycoside 5-10%,

Polyoxyethylene nonylphenol ether 5-10%,

Defoamer 0.04-0.08%,

Deionized water is mended to 100%.

Another object of the present invention is the preparation method of described train termination shellac clean-out system, carries out as follows:

(1) first add in reaction unit by disposable for water,

(2) then add citric acid, tripoly phosphate sodium STPP, stir and within 20-40 minute, make it form uniform liquor,

(3) add alkyl sodium sulfonate, alkyl glycoside, polyoxyethylene nonylphenol ether, fatty alcohol-polyoxyethylene ether successively in the liquor described in the most backward (2) step, stir, drip defoamer, stir and obtain solution of the present invention in 20-40 minute.

The present invention adopts technique scheme, the macula lutea that insect bodies, washmarking that the natural gum that can be stained with in high-speed cruising train motor-car vehicle body and windshield glass, birds droppings and clashing into produces cause, rust stain can full scale clearances, there is good cleaning effect, have the following advantages:

this product is the low bubble product of Compositional type, is applicable to cleaning, scrub, the various cleaning such as train automatic rinser;

foam is few, is applicable to clean, and washes the residual and watermark of rear non-foam and remains;

performance is gentle, on car body surface paint without impact;

product can compared with the shellac residue of good dissolving Train surface; Train component of machine can not be corroded.Two is that product performance of the present invention are gentle, to the paint on the outside surface of train body, and the fanout free region such as sealed strip, nondiscoloration, not containing chromic salt, nitrite, phosphoric acid salt; Odorlessness, environmentally safe, to human body fanout free region.The ODP value of product of the present invention is 0, can not destroy the ozonosphere in environment, is the substitute products of the clean-out system of ODS class.

Stability: refer to that composition placement prepared by the present invention observed solution delamination after 4-6 hour, stabilize to not stratified, not muddy, shakiness is decided to be layering or muddiness.

Cleaning rate: cleaning rate=wash mixed dirt weight/mixed dirt original weight.

Product stability of the present invention is good, not stratified, not muddy, and product of the present invention detects through Institute of Analysis of Jiangxi Province, and all technical all reaches requirement, and concrete all technical sees the following form 1,

Test atmosphere condition, temperature: 20 DEG C, humidity: 55%,

Test basis, GB, T44721984 etc.,

Testing instruments, automatical potentiometric titrimeter etc.,

Sample situation, sampling, liquid.

Table 1

From table, natural gum that product of the present invention is stained with in high-speed cruising train motor-car vehicle body and windshield glass, birds droppings are described and clash into macula lutea that the insect bodies, the washmarking that produce cause, rust stain cleaning force strong, corrosion-free to product, environmentally friendly, can not produce atmospheric ozone layer and destroy, foam is few, nonflammable etc.

embodiment: below in conjunction with specific embodiment, the present invention is described in further detail.

embodimentas following table 2

Illustrate: each component in embodiments of the invention is all commercially available.Defoamer of the present invention can select commercially available clean-out system defoamer or polyethers, high-carbon alcohols if polydimethylsiloxane of tributyl phosphate etc. or silicon class etc. is all by commercially available acquisition.
