Abstract

The invention discloses an efficient cleaning agent for stubborn dirt on the surface of a high-speed train. The cleaning agent is prepared from the following components in percentage by mass: 0.1 to 10 percent of a nonionic surfactant, 0.1 to 5 percent of essential oil, 0.1 to 20 percent of an oxygen-containing solvent, 0.5 to 15 percent of an alcohol solvent and 50 to 90 percent of water. A preparation method sequentially comprises the following steps: a, adding the water into a stirring kettle, and adding the nonionic surfactant, the oxygen-containing solvent and the alcohol solvent for mixing and uniform stirring; b, adding the essential oil for uniform stirring. A cleaning method comprises machine cleaning or manual cleaning, wherein machine cleaning is implemented by a universal cleaning machine for the train, and every 8 to 10 carriages are divided into a group for which 5 to 8 kilograms of cleaning agent is used at normal temperature; manual cleaning is implemented by preparing an about 5 percent cleaning solution from tap water and dipping the cleaning solution with cleaning cloth, a brush or a mop to scrub the surface of the train.

The quintessence oil is Oleum Terebinthinae, and main component is the mixture of terpenes.
The oxo solvent is two kinds of at least one or any proportioning in Propylene Glycol phenylate, dipropylene.
The alcohols solvent is two kinds of at least one or any proportioning in 2-Ethylhexyl Alcohol, furan furfuryl alcohol.
The water is deionized water.
A kind of preparation method of above-mentioned machine lubricating oil filter regeneration cleaning agent, is carried out as follows successively:
A. water is added in stirred tank, nonionic surfactant, oxo solvent and alcohols solvent is added and is mixed and stirred for Uniformly;
B. quintessence oil is added, is stirred.
C. the pH value of abluent is 6.5-8.5.
A kind of cleaning method using the stupid dirty efficient cleaner of above-mentioned high ferro Train surface, including machine washing or manual cleaning, Described machine washing is that used in train universal cleaning machine, 8-10 sections are organized into groups, 5-8 kilogram of consumption, and room temperature is used;Described is artificial Cleaning is to be configured to 5% or so cleanout fluid with tap water, dips in cleanout fluid with rag, hairbrush or mop and cleans Train surface.
The mutual compatibility effect of plurality of raw materials is present invention employs, especially lipophilic surfactant and water-soluble solvent are multiple Match somebody with somebody, taken into account the cleaning removal ability to water-based soils and oily dirt;Plant extract --- quintessence oil is a kind of Thief zone, height Moist type cleaning additive, can rapid osmotic, moistening dirt, thoroughly remove the stupid dirt of Train surface, this abluent pH so as to quick It is worth for 6.5-8.5, category neutral cleaners.
