Description
Technical field
The invention belongs to chemical treatment field, metallic surface, relate to concretely the preparation method of Chemical Colouring of Steel at Room Temperature liquid composite membrane-forming promotor and Chemical Colouring of Steel at Room Temperature liquid and this Chemical Colouring of Steel at Room Temperature liquid.
Background technology
The steel blackening technology is mainly used in the anticorrosion and decorative appearance of iron and steel parts.Blackening can be divided into two large classes, and a class is traditional high temperature blackening, and another kind of is New Process of Room Temperature Blackening.From the beginning of the eighties by American engineer invention Chemical Colouring of Steel at Room Temperature technology since because the room temperature blackening technology is compared the outstanding advantages such as have energy-saving and environmental protection, efficient with traditional high temperature blackening, be subject to social extensive concern.The development of technique experience many decades has had large increase qualitatively.The application of Chemical Colouring of Steel at Room Temperature technology increases also in continuous development.But in general, the application of room temperature blackening technology also is not very extensive.Most surface treatment producer still adopts traditional high temperature blackening in the reality.One of factor that it is important is exactly that is that all right is ripe for present room temperature blackening technology, also there is not good film forming accelerating, except only a few blackout prescription can be produced quality of forming film preferably the product, the blackout effect of the disclosed hair blackening liquid prescription of existing major part is all undesirable, and its common defective is:
1, the common fault of traditional normal temperature steel blackening liquid is that precipitation or postprecipitation phenomenon are serious, causes the unnecessary consumption of mass efficient composition, Efficiency Decreasing.This is because workpiece when blackout, the oxidized generation of steel substrate Fe
2+, Fe
2+Can be further oxided and be Fe
3+,

The generation of precipitation must consume the effective constituent tin anhydride of adding, makes Efficiency Decreasing.
2, also to have a defective that is difficult to overcome be that operating time model restriction is tighter to existing room temperature blackening product, and the blackout time is slightly long, and black film will occur a large amount of floating black, even loose scrapping.This is because its black film enough fine and closely woven, poor adhesive force not, and hair blackening liquid can penetrate that the film that has formed continues and metallic matrix reacts, and causes rete to be destroyed.
3, anticorrosive power is poor, and the workpiece salt mist experiment that the current ambient temperature blackening is processed was difficult to above 5 hours.
4, black film sticking power is insecure: several similar blackout product of selling on the market, and back and forth wipe its wear resistance at the blackout workpiece surface with the equal power of experiment filter paper and be difficult to above 100 times.
Summary of the invention
The object of the present invention is to provide a kind of sticking power and erosion resistance that can significantly improve black film, the Chemical Colouring of Steel at Room Temperature liquid film forming accelerating that film forming speed is fast.
Second purpose of the present invention is to provide the Chemical Colouring of Steel at Room Temperature that a kind of erosion resistance is strong, sediment is few, efficient is high liquid.The present invention also provides the preparation method of this kind Chemical Colouring of Steel at Room Temperature liquid.
The first purpose of the present invention is achieved in that a kind of Chemical Colouring of Steel at Room Temperature liquid composite membrane-forming promotor, is comprised of the following component of parts by weight: nitrocalcite 1-3 part, Jing Ti/Bao Pian COBALT NITRATE CRYSTALS/FLAKES 4-8 part, Sodium Tetraborate 2.5-5 part, m-nitrobenzene sulfonic acid 0.3-0.6 part.
Adopt technique scheme, this film forming accelerating is fit to exist the Chemical Colouring of Steel at Room Temperature liquid of phosphate radical, owing to having a large amount of phosphate anions in the hair blackening liquid, adds calcium salt and the cobalt salt of suitable proportion, these materials itself can form the phosphatoptosis layer in the metallic surface, such as Ca

2Deng, the film forming accelerating of having served as phosphatize phosphate coat.In addition, m-nitrobenzene sulfonic acid and Sodium Tetraborate also are effective phosphatize phosphate coat promotor, with the compound action of other composition in the solution, have accelerated phosphatic formation and composition ratio row in the black film, significantly improved sticking power and the erosion resistance of black film, film forming speed also increases.
As preferably: described Chemical Colouring of Steel at Room Temperature liquid composite membrane-forming promotor is comprised of the following component of weight fraction: nitrocalcite 2-3 part, Jing Ti/Bao Pian COBALT NITRATE CRYSTALS/FLAKES 5-7 part, Sodium Tetraborate 3-4 part, m-nitrobenzene sulfonic acid 0.4-0.5 part.
Another object of the present invention is achieved in that a kind of Chemical Colouring of Steel at Room Temperature liquid, take water as solvent, pH value is 2-3, and main component is copper sulfate 2～8g/L, tin anhydride 3～6.5g/L, potassium primary phosphate 2～10g/L, zinc nitrate 2～6g/L, single nickel salt 1～3g/L, composite membrane-forming promotor 2～6g/L, urea 3～8g/L, complexing agent 0.5-8g/L;
Described composite membrane-forming promotor is comprised of the following component of parts by weight: nitrocalcite 1-3 part, Jing Ti/Bao Pian COBALT NITRATE CRYSTALS/FLAKES 4-8 part, Sodium Tetraborate 2.5-5 part, m-nitrobenzene sulfonic acid 0.3-0.6 part.
Adopt technique scheme, for significantly improving of sticking power and anticorrosive power, mainly be based on the following principles of chemistry:
It is generally acknowledged, contain CuSe in the room temperature blackening film, FeSe, Fe
2(SeO
3)
3Deng composition, when containing phosphate radical in the hair blackening liquid, also can contain part FeHPO in the black film
4, FePO
4Deng phosphate component, thereby further improve the corrosion-resistant energy of black film and the bonding force of rete and metallic matrix.
Not firm in order to overcome the existing ubiquitous sticking power of room temperature blackening liquid, the defective that erosion resistance is poor, this programme has adopted a kind of " composite membrane-forming promotor ", experiment is found, the adding of this NEW TYPE OF COMPOSITE material, significantly improved sticking power and the erosion resistance of black film, film forming speed also increases.
Adopt this composite membrane-forming material that black film is produced modified effect, may be interpreted as from principle: have a large amount of phosphate anions the hair blackening liquid, add calcium salt and the cobalt salt of suitable proportion, these materials itself can form the phosphatoptosis layer in the metallic surface, such as Ca
