Abstract
The invention discloses phosphating liquor for surface treatment before automobile coating. The formula of the phosphating liquor comprises the following components in terms of mass concentration: 20-25g/L of phosphoric acid, 5-8g/L of diammonium hydrogen phosphate, 5-8g/L of sodium fluoride, 0.5-4g/L of cyclohexanehexol hexaphosphate, 1-3g/L of oxalic acid, 0.5-2g/L of boric acid, 0.2-0.5g/L of starch and 0.05-0.2g/L of ammonium molybdate. According to the phosphating liquor for surface treatment before automobile coating disclosed by the invention, the cyclohexanehexol hexaphosphate is adopted to replace nickel nitrate, so that the environmental pollution caused by nickel is reduced. Meanwhile, the phosphating liquor for surface treatment before automobile coating after phosphating treatment is less in residue, so that the service cycle of the phosphating liquor is enhanced. In addition, after surface treatment of the phosphating liquor for surface treatment before automobile coating disclosed by the invention, a disperse and multihole phosphating film can be formed so as to lay a good foundation for subsequent coating process, therefore, treatment for automobile coating is facilitated.
Description
Technical field
The present invention relates to a kind of Phosphating Solution for the painting dressing automobiles field.
Background technology
Vehicle coating process generally can be divided into the two parts: the one, and before application, metallic surface is processed, and also is pretreatment technology; The 2nd, the construction technology of application.Removing of old dope layer etc. when surface treatment mainly comprises greasy dirt, dust, the corrosion of removing workpiece surface and carries out repairing work, to improve the condition of surface of workpiece.Comprise according to various particular cases workpiece surface is carried out to mechanical workout and chemical treatment, 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 processing, 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 is to overcome existing defect, provides that a kind of gained phosphatize phosphate coat has strong corrosion resistant, residue is few and free of contamination painting dressing automobiles front surface is processed and used Phosphating Solution.
Purpose of the present invention is carried out specific implementation by the following technical programs:
A kind of painting dressing automobiles front surface is processed and is used Phosphating Solution, each component of this Phosphating Solution formula is by mass concentration, phosphoric acid 20-25g/L, Secondary ammonium phosphate 5-8g/L, Sodium Fluoride 5-8g/L, nucite six phosphoric acid fat 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.
As preferred version, above-mentioned painting dressing automobiles front surface is processed and is used Phosphating Solution, each component of this Phosphating Solution formula is by mass concentration, phosphoric acid 25g/L, Secondary ammonium phosphate 6.5g/L, Sodium Fluoride 5g/L, nucite six phosphoric acid fat 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 of the present invention is processed with Phosphating Solution and is adopted nucite six phosphoric acid fat to replace nickelous nitrate, has reduced the pollution of nickel to environment.Simultaneously, painting dressing automobiles front surface provided by the invention is processed with residue after the Phosphating Solution bonderizing few, has strengthened the life cycle of Phosphating Solution.In addition, painting dressing automobiles front surface provided by the invention is processed with Phosphating Solution after the surface treatment to the automobile mechanical parts, can form the phosphatize phosphate coat of one deck evacuation, porous, and follow-up coating process pad has been descended to good basis, more is conducive to the processing of painting dressing automobiles.
