Description
Technical field
The invention belongs to anticorrosive metal field, and in particular to a kind of relatively low aqueous chromium-free zinc-aluminum paint of sintering temperature and
Preparation Method And The Use.
Background technology
Traditional electrogalvanizing and hot dipping zinc technology because corrosion resistance is poor, energy consumption is big, it is seriously polluted, have hydrogen embrittlement, and use temperature
Degree is limited by passivating film aging temperature, can only be used below at 100 DEG C, there is significant limitation.
Aluminum Coating (Dacromet/steel) is incomparable due to having the advantages that traditional electrogalvanizing and galvanizing, thus
Needing the field of anticorrosive metal has wide application.Aluminum Coating is by zinc flake, aluminium powder and chromic anhydride etc. into packet
Into mixed liquor stir after be coated on workpiece surface, then sintering curing, redox reaction forms unbodied
nCr2O3·mCrO3Complex salt.
However, containing Cr in Aluminum Coating6+, Cr6+Strong toxicity and there is carcinogenesis, environment for human survival can be caused sternly
Heavily contaminated, therefore the use of chromium has been subjected to increasingly stricter limitation.European 2000/53/EG regulations, from July 1st, 2003
Rise, in each automobile that Europe produces and sells, the content of Cr VI must not exceed 2g, in the corrosion-inhibiting coating used on automobile
Do not allow to contain Cr6+.Many brand vehicles also take the lead in having formulated without chrome coating in the automobile industry of industrially developed country in the world
Technical standard.
Additionally, the sintering temperature of Dyclo paint it is general at 300 DEG C and more than, sintering temperature is high, and power consumption is big.Therefore, zinc
The Trend of Chrome-free of aluminized coating is extremely urgent.
At present, Delta and Geomet are typical chromium-free zinc aluminum coating, but both material prices are all higher.Geomet
The German spot price of slurries is 40 Euros/kilogram, and the Japanese spot price of Geomet Geomet slurries is 1750 yen/kilogram, by
This estimates that they all should be more than 250 yuans/kilogram in the sale price of China.It is expensive.
The content of the invention
(generally greater than 300 DEG C) higher for existing Aluminum Coating sintering temperature, high cost is, it is necessary to use environmental pollution
The defects such as larger organic solvent, primary and foremost purpose of the invention is that a kind of environmental pollution of offer is smaller, low cost, sintering temperature
The low chromium-free zinc aluminum coating of degree.
Preparation method another object of the present invention is to provide above-mentioned chromium-free zinc aluminum coating.
It is still another object of the present invention to provide the purposes of above-mentioned chromium-free zinc aluminum coating.
The purpose of the present invention is achieved through the following technical solutions：
A kind of chromium-free zinc aluminum coating, contains mass ratio (1.0-1.5):1.0 component A and component B, also containing account for component A,
The polyether-modified dimethyl siloxanes of B gross masses 1-2%, 0.2-0.5% hydroxyethyl ether celluloses and 0.5-0.7% defoamers；
In this formula, polyether-modified dimethyl siloxane as coating dispersant and levelling agent, in can making coating
Metal-powder dispersion evenly, the coating for obtaining is more smooth；Hydroxyethyl ether cellulose as coating thickener, defoamer
Eliminate the unwanted bubbles in dope preparing process.
Described component A is by following mass percent into being grouped into：
In component A, MTMS is the film forming matter of coating, and deionized water is MTMS
Hydrolysis auxiliary agent, methyl alcohol or ethanol can make the hydrolysis of component A more stable, and sodium phosphomolybdate is the corrosion inhibiter of coating, can strengthen painting
The decay resistance of layer.
Described component B is by following mass percent into being grouped into：
In component B, sheet aluminum zinc powder is the powder section of coating.Ethylene glycol and ethanol are protected as the moistening of metal-powder
Shield agent, on the one hand can make the powder in coating be easier dispersion, on the other hand can mitigate the metal-powder sintering curing in coating
During oxidation reaction.Tween can eliminate the unwanted bubbles occurred during coating preparation, and can strengthen the corrosion resistance of coating
Energy.Polyoxethylene octylphenyl phenol ether is surfactant, promotes clagging in by protection matrix.
Relative to particulate zinc aluminium powder, sheet aluminum zinc powder can play wall effect, and sheet aluminum zinc powder stratiform is overlapped, can more had
The corrosive medium contact matrix such as effect ground resistance dash, oxygen, saves metal-powder consumption；
The preferred polysorbas20 of described tween；
The preferred polyoxethylene octylphenyl phenol ether -10 of described polyoxethylene octylphenyl phenol ether.
The preparation method of above-mentioned chromium-free zinc aluminum coating, comprises the following steps：
(1) MTMS and alcohol are first put into, are stirred evenly, be subsequently adding deionized water and obtain hydrolyzate, adjust water
Solution liquid pH value is 3.5-5.5, and hydrolyzate is stirred 1-1.5 hours at 20-30 DEG C, finally adds sodium phosphomolybdate stirring 1.5-
2.5 hours, obtain component A；
The preferred rotating speed 500r/min of described stirring；
(2) take flake zinc aluminium powder, add ethylene glycol and ethanol, then be added dropwise polyoxethylene octylphenyl phenol ether and
Tween20, stirs evenly to obtain component B；
(3) component A and component B are mixed, and be put into polyether-modified dimethyl siloxane, hydroxyethyl ether cellulose and
Defoamer, stirring obtains chromium-free zinc aluminum coating after 1.5-2.5 hours.
Above-mentioned chromium-free zinc aluminum coating can be applied in anticorrosion field, and application method is as follows：
Derusting by sandblasting treatment is carried out to protected matrix surface, sandblasting particle diameter is 20-30 mesh, is subsequently placed in acetone or second
Ultrasonic cleaning 5min is carried out in alcohol；Matrix is brushed with chromium-free zinc aluminum coating, or is dipped in coating and is taken out after 10s, then
It is heated into more than 10min at 70-100 DEG C carries out prebake, the water in coating is slowly volatilized with alcohol, prevents coating in height
In warm sintering process, water alcohol evaporation rate is too fast, causes coating hole occur, reduces the antiseptic property of coating；Finally will drying
Matrix at 220-250 DEG C sintering curing 25-30min.
The present invention has the following advantages and effect relative to prior art：
1st, the low production cost of coating of the present invention, it is only necessary to 100 yuan/kilogram；2nd, prior art sintering temperature be 300 DEG C with
On, this coating just can realize sintering at 220-250 DEG C, it is possible to decrease the heating facility requirement of production scene and energy consumption；3、
Not using has the organic solvent of larger pollution to environment, environmentally friendly.
