Abstract
The invention discloses a galvanized sheet treating agent before application, which is prepared from the following raw materials in mass concentration: 5-10 g/L nickelous fluoride, 6-11 g/L cobalt acetate, 3-5 g/L ferric ammonium oxalate, 1-3 g/L 2-sulfophenylpropionic acid, 1-3 g/L 4-sulfo-o-phthalic acid, 0.2-0.5 g/L crude anthracene and the balance of water. The galvanized sheet treating agent before application is non-toxic and environment-friendly, is free of hexavalent chrome heavy metal ions, has excellent properties, and can greatly enhance the binding force of the galvanized sheet with the coating and the corrosion resistance of the galvanized sheet. The treating agent disclosed by the invention has the advantages of simple use technique and short treatment time, and is convenient for large-scale practical production.
Description
Technical field
The present invention relates to a kind of metal conditioner, specifically a kind of for galvanized sheet Coating Pretreatment, take and improve the treatment agent that coating binding force and solidity to corrosion are object.
Background technology
Surface of steel plate is zinc-plated is the conventional means that improves steel plate antiseptic power, due to the zinc coating formation hickie that is especially easily corroded in wet environment in air, thus must after zinc-plated, carry out Passivation Treatment, to improve its corrosion resisting property.Through surface passivation, can effectively prevent that white rust from generating, and plays the effect of the bonding force that improves galvanized sheet and follow-up coating layer simultaneously.What generally adopt traditionally is that chromating is processed, and this technique is simple, cost is low, binding force of membrane is good, solidity to corrosion is high, has self-repairing capability and re-workability simultaneously, becomes the conventional passivation means of countries in the world.But because sexavalent chrome belongs to carcinogenic substance, its product and production process thereof can produce serious harm to human and environment, so countries in the world have started legislation, ban use of or avoid chromating technique as far as possible.Therefore, what exploitation made new advances replaces traditional passivation technology without chromium process, is to adapt to New Times environmental protection megatrend, keep and improve galvanizing production competitive power in the urgent need to.
At present; although galvanized sheet chromium-free deactivation technology has obtained positive progress; on existing market, most product has also reached environmental requirement; but these products can't reach the performance of traditional passivation on the application matching performance with follow-up coating; especially show in coating binding force and whole solidity to corrosion, can not meet the requirement of large-scale production.
Summary of the invention
The object of this invention is to provide a kind of bonding force and corrosion proof Coating Pretreatment agent that can be used for galvanized sheet chromium-free deactivation that can significantly improve galvanized sheet and coating.
The present invention adopts following technical scheme to achieve these goals:
The agent of galvanized sheet Coating Pretreatment, is characterized in that: the raw material by following mass concentration forms:
Nickelous fluoride 5-10 g/L
Cobaltous diacetate 6-11 g/L
Ammonium ferric oxalate 3-5 g/L
2-sulphophenyl propionic acid 1-3 g/L
4-sulfo group phthalic acid 1-3 g/L
Crude anthracene 0.2-0.5 g/L
Water surplus
Preferably, the agent of a kind of galvanized sheet Coating Pretreatment, is characterized in that: the raw material by following mass concentration forms:
Nickelous fluoride 8 g/L
Cobaltous diacetate 9 g/L
Ammonium ferric oxalate 4 g/L
2-sulphophenyl propionic acid 2 g/L
4-sulfo group phthalic acid 2 g/L
Crude anthracene 0.35 g/L
Water surplus
By creationary research, find, nickelous fluoride and Cobaltous diacetate are under the existence condition of ammonium ferric oxalate, on galvanized sheet surface, can generate the micron-sized metal alloy particle layer with strong adhesive force of one deck, this metal alloy layer even compact, has improved the solidity to corrosion of galvanized sheet.As the bottom of application, the alloy layer that the present invention generates on galvanized sheet, has strengthened the bonding force of follow-up coating and galvanized sheet greatly.Meanwhile, 2-sulphophenyl propionic acid, 4-sulfo group phthalic acid, crude anthracene add the stability that has greatly improved treatment agent, be convenient to actual production and use.
Preparation method of the present invention: in quantitative water, add successively each raw material weighing according to above-mentioned mass concentration, be stirred to and dissolve completely and get final product.
Usage of the present invention: galvanized sheet workpiece is after degreasing is cleaned, and the treatment agent of the present invention that is 3% ~ 5% by mass concentration is processed 5-10 minute under the condition of 10-30 ℃, and processing mode can be spraying process or pickling process.Washing can enter coating process after drying.
Beneficial effect of the present invention:
Galvanized sheet Coating Pretreatment agent asepsis environment-protecting of the present invention, containing sexavalent chrome heavy metal ion, excellent performance, can significantly improve bonding force and the solidity to corrosion of galvanized sheet and coating.Treatment agent operation of the present invention is simple, and the treatment time is short, is convenient to extensive actual production and uses.
