Abstract
The invention discloses a low-foam metal detergent. The detergent comprises following components by weight percent: 0.3-5.0% of sodium dodecyl sulfate, 1.0-3.6% of alkylolamide, 5-8% of diethanol amine, 0.2-3.0% of zinc sulfate, 10-12% of glucolactone, 3-6% of sodium carbonate, 0.3-1.2% of dipropylene glycol ether, 0.1-0.3% of fluoro alkyl modified polysiloxane, 0.9-2.0% of sodium hydroxide and 50-79% of deionized water. The low-foam detergent has the beneficial effects that dirt on the surface of the metal is effectively cleared, and the surface of the metal is effectively protected due to the low alkaline; fluoro alkyl modified polysiloxane is used as a defoamer, so that the detergent has the characteristics that foam is low and rinsing is easy; the low-foam metal detergent contains no phosphor, is easy to degrade, and has no pollution to the water body and the environment.
Description
Technical field
The present invention relates to a kind of metal detergent, particularly to one kind low bubble metal detergent and preparation method thereof.
Background technology
In the maintenance and repair of machining, plant equipment, automobile etc., diesel oil, coal Water Oil Or Gas are mostly adopted to make clear
Washing lotion is cleaning part.This not only wastes the energy, and there is potential unsafe factor, careless slightly, then may lead to fire
Calamity.Therefore, a kind of new metal cleaner is gradually widely used, it can well diesel oil substitute, kerosene and
Gasoline is cleaning part, and low price, using safety, it is well suited for mechanized cleaning operation.Metal cleaner can go
Go to degrease except metal material surface, grease, dirt, without there being rust staining.
Metal cleaner refers to go to degrease for metal material surface, the industrial cleaning agent of grease, dirt or greasy dirt
Cleaning agent.Metal cleaner apply in the industrial production quite varied, be usually used in surface degreasing before and after intermetallic composite coating, scale removal and
Cleaning before finished product assembling or packaging.In the electronics industry, also must be washed away using cleaning agent after printed circuit plate weld
The Harmful Residue.Additionally, also usually using metal cleaner during plant equipment maintaining.
Metal detergent is divided into solvent metal cleaning agent and water-base metal detersive again.Compared with solvent metal detersive,
Water base metal cleaning agent does not contain organic solvent, be by mean of containing surfactant, emulsifying agent, the wetting of bleeding agent etc.,
Emulsification, infiltration, dispersion, solubilising etc. act on to realize the cleaning dirty to metal surface greasy dirt, grease, wax.
Water-base metal detersive is because it is cheap, clean result is good in recent years.Receive the welcome in market, however, existing
Some water-base metal detersives still suffer from certain defect, for example：Foam is excessively difficult to rinse；Phosphorus element-containing, can cause water body
Pollution；Contained substance is not degradable, and environment is worked the mischief.
Therefore, one kind can effective cleaning metal, can prevent metal surface from getting rusty after cheap, cleaning, and low bubble
Easily rinse, also not phosphorous, degradable metal cleaner receives the widespread demand in market.
Content of the invention
It is an object of the invention to provide one kind can effective cleaning metal and cheap, cleaning after can prevent metal
Surface oxidisation；And low bubble, easily rinsing；Also not phosphorous, degradable metal cleaner
To achieve these goals, the present invention is made up of as following weight percent following material：
Dodecyl sodium sulfate 0.3～5.0%, alkylolamides 1.0～3.6%, diethanol amine 5～8%, corrosion inhibiter
0.2～3.0%, glucolactone 10～12%, sodium carbonate 3～6%, dipropylene glycol methyl ether 0.3～1.2%, fluorine silicon
Defoamer 0.1～0.3%, NaOH 0.9～2.0% and deionized water 50～79%.
Preferably, described each component is respectively by weight percentage：Dodecyl sodium sulfate 2.5%, alkylolamides
2.5%th, diethanol amine 6%, corrosion inhibiter 2%, glucolactone 10%, sodium carbonate 3%, dipropylene glycol methyl ether 1.1%,
Fluorine silicon defoaming agent 0.2%, NaOH 1.7% and deionized water 71%.
Preferably, described fluorine silicon defoaming agent is fluorohydrocarbon base modified polyorganosiloxane.
Preferably, described corrosion inhibiter is zinc sulfate.
A kind of preparation method of low foam metal cleaner：First by dodecyl sodium sulfate, zinc sulfate, glucolactone,
Sodium carbonate and NaOH proportionally mix, and add and are stirred with a small amount of deionized water dissolving, then according to ratio adds
Enter alkylolamides, ethylene glycol amine, dipropylene glycol methyl ether stir, finally proportionally add the modified poly- silicon of fluorohydrocarbon base
Oxygen alkane and deionized water, stir and obtain final product the present invention low bubble metal detergent.
Preferably, during use by temperature control at 40～65 DEG C.
The invention has the beneficial effects as follows：1st, the spot of metal surface can effectively be removed, due in low alkalinity, Neng Gouyou
The protection metal surface of effect；2nd, defoamer is done using fluorohydrocarbon base modified polyorganosiloxane, make cleaning agent have the spy of Low-foam and easily rinsing
Property；3rd, not phosphorous, degradable for water body with environmental nonpollution.
