Abstract
The invention discloses a kind of painting dressing automobiles front surface process Phosphating Solution, each component of this Phosphating Solution formula by mass concentration, phosphoric acid 20-25g/L, Secondary ammonium phosphate 5-8g/L, Sodium Fluoride 5-8g/L, nucite six phosphoric acid ester 0.5-4g/L, oxalic acid 1-3g/L, boric acid 0.5-2g/L, starch 0.2-0.5g/L, ammonium molybdate 0.05-0.2g/L.Painting dressing automobiles front surface process Phosphating Solution of the present invention adopts nucite six phosphoric acid ester to replace nickelous nitrate, decreases the pollution of nickel to environment.Meanwhile, after painting dressing automobiles front surface process Phosphating Solution bonderizing provided by the invention, residue is few, enhances the life cycle of Phosphating Solution.In addition, painting dressing automobiles front surface process Phosphating Solution provided by the invention, to after the surface treatment of automobile mechanical parts, can form the phosphatize phosphate coat of one deck evacuation, porous, descend good basis, be more conducive to the process of painting dressing automobiles to follow-up coating process pad.
Description
Technical field
The present invention relates to a kind of for the Phosphating Solution in painting dressing automobiles field.
Background technology
Vehicle coating process, generally can be divided into two parts: one is metallic surface process before application, is also pretreatment technology; Two is construction technologies of application.Surface treatment mainly comprises the removing etc. of old dope layer when removing the greasy dirt of workpiece surface, dust, corrosion and carry out repairing work, to improve the condition of surface of workpiece.Comprise, according to various particular case, mechanical workout and chemical treatment are carried out to workpiece surface, as phosphatization, oxidation and Passivation Treatment.Phosphatization is the critical process of pretreatment technology, directly affects the quality of painting dressing automobiles.
At present, for the Phosphating Solution of painting dressing automobiles front surface process, mainly there is the defect of following several respects:
1, nickel content is high, and environmental pollution is serious;
2, the residue in Phosphating Solution is too much;
3, corrosion-resistant.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of gained phosphatize phosphate coat and have the few and free of contamination painting dressing automobiles front surface process Phosphating Solution of strong corrosion resistant, residue.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of painting dressing automobiles front surface process Phosphating Solution, each component of this Phosphating Solution formula by mass concentration, phosphoric acid 20-25g/L, Secondary ammonium phosphate 5-8g/L, Sodium Fluoride 5-8g/L, nucite six phosphoric acid ester 0.5-4g/L, oxalic acid 1-3g/L, boric acid 0.5-2g/L, starch 0.2-0.5g/L, ammonium molybdate 0.05-0.2g/L.
Preferably, above-mentioned painting dressing automobiles front surface process Phosphating Solution, each component of this Phosphating Solution formula by mass concentration, phosphoric acid 25g/L, Secondary ammonium phosphate 6.5g/L, Sodium Fluoride 5g/L, nucite six phosphoric acid ester 3.5g/L, oxalic acid 2.5g/L, boric acid 1.3g/L, starch 0.4g/L, ammonium molybdate 0.08g/L.
Beneficial effect of the present invention:
Painting dressing automobiles front surface process Phosphating Solution of the present invention adopts nucite six phosphoric acid ester to replace nickelous nitrate, decreases the pollution of nickel to environment.Meanwhile, after painting dressing automobiles front surface process Phosphating Solution bonderizing provided by the invention, residue is few, enhances the life cycle of Phosphating Solution.In addition, painting dressing automobiles front surface process Phosphating Solution provided by the invention, to after the surface treatment of automobile mechanical parts, can form the phosphatize phosphate coat of one deck evacuation, porous, descend good basis, be more conducive to the process of painting dressing automobiles to follow-up coating process pad.
