Abstract
The present invention relates to a technology for forming a transformation film on the surface of aluminum and aluminum alloy. In the technology, the aluminum or the aluminum alloy is positioned in tank liquor for processing, wherein the tank liquor comprises 0.05 to 1.0 g/L of titanium ions, 0.05 to 1.50 g/L of zirconium ions, 0.01-2.0 g/L of phosphate radical ions, 0.05-1.5 g/L of fluorine ions, 0.05 to 3.0 g/L of water-soluble organic polymer, the pH value of the tank liquor is 2 to 4, and the temperature of the tank liquor is higher than or equal to 15 DEG C. Processing time is 3 to 8 minutes. Thus, the transformation film is formed on the surface of the aluminum or the aluminum alloy, and has good anticorrosion performance and favorable adhesive force and impact performance for organic coating. All performance of the transformation film reaches China standard performance requirements. The present invention has the characteristics of stabile tank liquor, simple technological parameter control, few sediment and easy maintenance and control in production. In addition, the technology can be widely used for processing impregnating or spraying transformation films of aluminum products, construction aluminum sections, aluminum alloy castings, etc.
Description
Technical field
The present invention relates to a kind of technology at aluminium and alloy surface formation conversion film thereof.
Background technology
Aluminium belongs to the active metal, can generate one deck natural oxide film under the effect of oxygen in air, and this tunic is very thin, and is comparatively loose, can not reach the requirement of coating quality.Form conversion film at aluminium and aluminum alloy surface, at present widely used is the chromic salt oxidizing process, though this technology is simple to operate, tank liquor is stable, the conversion film excellent property that is generated, but its deleterious sexavalent chrome causes great harm to environment, and its wastewater treatment incurs great expense, and the sexavalent chrome that especially remains in aspect handling products such as aluminium matter beverages can, aluminum products in the oxide film can cause very big harm to people are healthy.Therefore, along with the reinforcement of people's Environmental awareness, containing the chromium pretreatment technology will be very restricted.
Summary of the invention
The object of the present invention is to provide a kind of environment-protective process that forms conversion film on aluminium and alloy surface thereof, the conversion film excellent property that this technology generates can fully satisfy the technical requirements of coating quality.
A kind of technology provided by the invention at aluminium and alloy surface formation conversion film thereof, this technology is to place the tank liquor that contains titanium ion concentration 0.05～1.0 grams per liter, zirconium ion concentration 0.05～1.50 grams per liter, phosphorus acid ion concentration 0.01～2.0 grams per liter, fluorinion concentration 0.05～1.5 grams per liter, soluble epoxide polymkeric substance or water-soluble acrylic polymer concentration 0.05～3.0 grams per liter, pH value 2～4, temperature 〉=15 ℃ to handle aluminum or aluminum alloy, in 3～8 minutes treatment times, can on the aluminum or aluminum alloy surface, generate one deck conversion film.
Treatment process of the present invention comprises that dip treating, spray are handled or both combined treatment.
The present invention utilizes nontoxic titanium, zirconium to substitute deleterious hexavalent chromium, under oxygenant and catalyzer and effect at organic polymer, on aluminium and alloy surface thereof, form certain thickness, even, fine and close conversion film, the performance requriements that every performance of the conversion film that is obtained is up to state standards, this conversion film have good anti-corrosion-performance and with the good sticking power of organic coating tool and impact property etc.Technology of the present invention has that normal temperature is handled, tank liquor is stable, processing parameter control is simple, sediment is few, be convenient to the characteristics safeguarding and control in producing, and the dipping or the spray conversion film that are widely used in aluminum products, architectural aluminum section, aluminum alloy casting etc. are handled.
