Abstract
The present invention relates to the preparation method of a kind of phosphatization liquid of metal finishing use.This phosphatization liquid use temperature is 25-35 ℃, in same tank liquor, handled 20-30 minutes, disposable oil removing, rust cleaning, phosphatization, the passivation comprehensive function that just can finish metal works, operation is few, facility investment is few, working area is little, the formed after treatment phosphatize phosphate coat crystallization of workpiece even compact, marshalling, and its film heavily is 4-30g/m
2Controlled, corrosion stability and insulativity height are strong to the coating bonding force.The use stable performance, few with the back sediment, be easy to administer and regeneration.
Description
The invention belongs to the preparation method of the metal surface treating liquid in the applied chemistry.
At present, have oil removing, rust cleaning, phosphatization, the multi-functional metal phosphorizing liquid of passivation concurrently, have high temperature phosphorization liquid (use temperature is at 80-98 ℃) and medium temperature phosphating solution (use temperature is at 50-70 ℃) to amount to five kinds, its prescription can be found from " antirust technology ", " antirust workbook ", " chemical industry small commodity production method " and books and periodicals such as " electroplating technology handbooks ".But use temperature does not see as yet that at 25-40 ℃ multifunctional low-temperature metal phosphorizing liquid report is arranged.
The object of the present invention is to provide a kind of multifunctional low-temperature metal phosphorizing liquid, this phosphatization liquid has the disposable comprehensive function of finishing oil removing, rust cleaning, phosphatization, passivation in same tank liquor to metal works, and its use temperature is at 25-35 ℃.
Prescription of the present invention is as follows, and its various component contents mean contained gram number or milliliter number in every premium on currency solution.
Zinc oxide: 50-75g zinc nitrate: 240-280g
Nitric acid: 3-6ml Sodium Nitrite: 1.2-1.8g
Phosphoric acid: 180-230g Sodium Fluoride: 3.5-4.4g
Citric acid: 1.3-2.1g trolamine: 4-7g
Ammonium molybdate: 0.7-1.4g tensio-active agent (AES): 8-12g
Magnesium chloride: 30-40g emulsifying agent (OP-10): 4.5-6.3g
Potassium bichromate: 0.3-0.5g water: add to 1 liter
As follows by above-mentioned prescription compound method of the present invention:
(1) preparation of A solution: zinc oxide is added an amount of distilled water or deionized water furnishing pasty state, adds nitric acid again, under agitation slowly add phosphoric acid then, and be heated to the boiling make it to dissolve fully transparent.
(2) preparation of B solution: in container, put into 2/3 of institute's water requirement, under agitation condition, add ammonium molybdate, Sodium Nitrite, Sodium Fluoride, magnesium chloride, zinc nitrate, citric acid and potassium bichromate, make it molten entirely.
(3) preparation of whole soln: the A solution for preparing is slowly added in the B solution for preparing, and add again after mixing trolamine, surfactant A ES and emulsifier op-10 make it complete molten evenly, clear gets final product.
By above-mentioned prescription and the prepared multifunctional low-temperature metal phosphorizing liquid of the present invention of compound method, its outward appearance is green clear, the pH value 0.2-0.8 of solution, relative density (g/ml) 1.2-1.35, free acidity (point) 4-12, total acidity (point) 180-240.
It is 25-35 ℃ that the present invention handles the metal works service temperature, handles to get final product disposable oil removing, rust cleaning, phosphatization and the passivation comprehensive function finished in 20-30 minute in same tank liquor.Operation sequence is few, only needs the 3-4 procedure just can replace the 23-27 procedure of conventional phosphating process, significantly reduces the investment and the working area of equipment, and is easy to realize mechanize and automatization.Workpiece after phosphatization liquid of the present invention is handled, formed phosphatize phosphate coat crystallization even compact, marshalling, its film focuses on 4-30g/m
2Controlled, corrosion stability and insulativity height are strong to the coating bonding force; The use solution property is stable, and is few with the back sediment, is easy to administer and regeneration.
The embodiment of the invention sees the following form:
