Abstract
The invention discloses an aluminum alloy treating agent before application, which is prepared from the following raw materials in mass concentration: 8-10 g/L nickelous fluoride, 6-8 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 aluminum alloy 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 aluminum alloy with the coating and the corrosion resistance of the aluminum alloy. 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 the aluminium alloy Coating Pretreatment, to improve coating binding force and solidity to corrosion as the treatment agent of purpose.
Background technology
Aluminium alloy is little due to proportion, conductive and heat-conductive good, mechanical property is excellent, be easy to the advantages such as machine-shaping and be widely used in every profession and trade, but the oxide film that himself forms under physical environment is difficult to resist the corrosion of environment, and the corrosion of aluminum alloy materials all occurs around us all the time.
The main method that is used at present the aluminium alloy Coating Pretreatment is the chromating method.Aluminum alloy materials after Passivation Treatment, can strengthen self corrosion resistance nature and and coating between sticking power, improve corrosion resistance nature.This technique is simple, cost is low, binding force of membrane is good, solidity to corrosion is high, has simultaneously self-repairing capability and re-workability, 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 begun 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 the alloy product competitive power in the urgent need to.
At present; although the aluminium alloy non-chromium passivating technique has been obtained positive progress; on the existing market, most product has also reached environmental requirement; but these products with the application matching performance of follow-up coating on can't reach the performance of traditional passivation; especially show on coating binding force and whole solidity to corrosion, can not satisfy the requirement of large-scale production.
Summary of the invention
The purpose of this invention is to provide a kind of bonding force and corrosion proof Coating Pretreatment agent that can be used for the aluminium alloy non-chromium passivation that can significantly improve aluminium alloy and coating.
The present invention adopts following technical scheme to achieve these goals:
The agent of a kind of aluminium alloy Coating Pretreatment is characterized in that: the raw material by following mass concentration forms:
Nickelous fluoride 8-10 g/L
Cobaltous diacetate 6-8 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 aluminium alloy Coating Pretreatment is characterized in that: the raw material by following mass concentration forms:
Nickelous fluoride 9 g/L
Cobaltous diacetate 7 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
Find by creationary research, nickelous fluoride and Cobaltous diacetate are under the existence condition of ammonium ferric oxalate, can generate the micron-sized metal alloy particle layer with strong adhesive force of one deck in aluminum alloy surface, this metal alloy layer even compact has improved the solidity to corrosion of aluminium alloy.As the bottom of application, the alloy layer that the present invention generates on aluminium alloy has strengthened the bonding force of follow-up coating and aluminium alloy greatly.Simultaneously, 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 according to above-mentioned mass concentration weighing, be stirred to dissolving fully and get final product.
Usage of the present invention: after Al alloy parts is cleaned through degreasing, be that 3% ~ 5% treatment agent of the present invention was processed 5-10 minute under the condition of 10-30 ℃ with mass concentration, processing mode can be spraying process or pickling process.Can enter coating process after the washing oven dry.
Beneficial effect of the present invention:
Aluminium alloy Coating Pretreatment agent asepsis environment-protecting of the present invention does not contain the sexavalent chrome heavy metal ion, and excellent performance can significantly improve bonding force and the solidity to corrosion of aluminium alloy 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.
