Description
Technical field
The present invention relates to cleaning agent fields, specifically, being a kind of aqua type metal cleaner and its system of high-efficiency environment friendly
Preparation Method.
Background technology
Metal material is before processing and handling, usually in its surface the antirust oil and machine that there are one layer based on mineral oil
Greasy dirt is processed, needs to start the cleaning processing before following process.Currently used metal cleaner have solvent type, half solvent type and
Aqua type etc., solvent by impregnate and quick-drying in a manner of be widely used in the oil removing and degreasing of various metals.In most cases, molten
Other substances are not added in agent or only add a small amount of stabilizer or surfactant.But due to recycling/recycle unit and
Operation sequence is expensive, the harm to the limitation and organic solvent of volatile organic compound (VOC) to environment and health, uses
The case where 100% organic solvent is cleaned is being reduced.
Water base metal cleaning agent production cost is relatively low, and good environmental protection is widely used.Existing water-base metal
Cleaning agent is mostly with alkyl phenol polyoxyethylene ether (OP-10), nonylphenol polyoxyethylene ether (NP-10), sodium alkyl benzene sulfonate (LAS)
The surfactant of compounding is main component.Since OP class surfactants are difficult to biodegradation, there is an urgent need for a kind of biological degradabilities
High, effect on environment is small surfactant and auxiliary agent replaces existing aqua type metal cleaner.

30min is reacted, room temperature is cooled to, the aqua type metal cleaner is made.
An embodiment according to the present invention, the temperature in the step S200 are controlled at 60 DEG C.
An embodiment according to the present invention is cooled to 35 DEG C in the step S300.
Specific implementation mode
It is described below for disclosing the present invention so that those skilled in the art can realize the present invention.It is excellent in being described below
Embodiment is selected to be only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
A kind of aqua type metal cleaner is mainly by surfactant, magnesium silicate, sodium dihydrogen phosphate, sodium tripolyphosphate, N-
Glycine, secondary thioether butyl oleate ammonium salt, glycerine and water composition, wherein the surfactant is cocamidopropyl propyl amide
The mixed surfactant of glycine betaine (CAB-30), alkyl ether imidazoline and fatty alcohol polyoxyethylene ether.
The each component of the aqua type metal cleaner and its shared mass percent are：Cocoamidopropyl betaine 5
~10%, alkyl ether imidazoline 2~3%, fatty alcohol polyoxyethylene ether 1~2%, sodium dihydrogen phosphate 6~12%, sodium tripolyphosphate
2~4%, magnesium silicate 3~5%, glycerine 8~16%, secondary thioether butyl oleate ammonium salt 3~4%, N- glycine 2~4% is remaining
Amount is water.
Wherein, CAB-30 is selected from Tianjin Se Feisi Fine Chemical Co., Ltd.
Since calcium ion, the magnesium ion in water can be such that the degreasing rate of surfactant reduces, by being added in cleaning agent
Sodium tripolyphosphate is able to chelates ferric ions, calcium ion and magnesium ion, and after sodium tripolyphosphate and N- glycine compound, to chelating
The ability of iron ion, calcium ion and magnesium ion is further strengthened, the effect for playing dispersion, being coordinated, preventing greasy dirt redeposition,
Improve the degreasing rate of surfactant.
The aqua type metal cleaner further includes 21,2- ethylenetriamine pentacetic acids, a small amount of Asias 21,2- second
The addition of base pentaacetic acid can further increase the ability of its chelated metal ions, but excessive addition can lead to its chelating
The ability of metal ion declines, and the mass percents of currently preferred 21,2- ethylenetriamine pentacetic acids is 0.3~
1.2%.
Wherein, there are five acetic acid for 21,2- ethylenetriamine pentacetic acids tool, have good metal to calcium, iron, magnesium plasma
Chelation, N- glycine can enhance the ability of sodium tripolyphosphate chelates ferric ions, calcium ion and magnesium ion, especially to calcium ion
Obvious, in the case where there is glycine, phosphate radical more preferably can react to form calcium phosphate with calcium ion.
Wherein, sodium tripolyphosphate, sodium dihydrogen phosphate are able to adjust the pH value of solution, 21,2- ethylenetriamine pentacetic acids
It can play the role of auxiliary adjustment pH, meanwhile, sodium dihydrogen phosphate can also improve cleaning dispersion performance, improve the de- of surfactant
Fat ability.
Wherein, magnesium silicate is dispersed in the cleaning agent, and the dirt on adsorbing metal surface, oil are used for as adsorbent
Fat.
It needs to cooperate between surfactant, CAB-30 has good decontamination, conditioning, antistatic property；And have
There is good viscosity-adjusting agent to act on.Stablize in extensive pH value range, small to skin and eye irritation of anion, sun
Ion, nonionic and other amphoteric surfactantes have preferable compatibility.Wherein, alkyl ether imidazoline is amophoteric surface active
Agent.Fatty alcohol polyoxyethylene ether is nonionic surfactant, and the ehter bond in molecule is not easy to be destroyed by acid, alkali, so stability
Higher, water-soluble preferably electrolyte-resistant is readily biodegradable, and foam is small, fatty alcohol polyoxyethylene ether and other surfaces activating agent
Compatibility it is good.Insensitive to hard water, cold washing performance is good, but with the raising of water temperature, and solubility can continuously decrease.
In the range of pH is 3~11, fatty alcohol polyoxyethylene ether hydrolysis-stable.
Wherein, the addition can effectively protect metal material of fatty alcohol polyoxyethylene ether, while preventing or slowing down metal material
Corrosion.
The preparation method of the aqua type metal cleaner, including step：
S100 uniformly mixes glycerine with deionized water, and magnesium silicate, sodium tripolyphosphate are added into mixed liquor, and stirring is equal
It is even；
