Abstract
The invention belongs to the field of fine chemical engineering and relates to a phosphating solution. The phosphating solution comprises the following components by concentration: 25-50g/L manganous dihydrogen phosphate, 50-80g/L zinc nitrate and deionized water used as a solvent. The phosphating solution provided by the invention has a simple formula; a uniform phosphate coating is formed on a steel plate within a short period of time; after the phosphating solution is painted and dried, a beautiful paint film is formed; and the bonding strength is increased.
Description
Technical field
The invention belongs to field of fine chemical, relate to a kind of Phosphating Solution.
Background technology
Iron and steel parts is antirust and decorate the processing of all will spraying paint, and for example the car shell will carry out baking vanish, to increase aesthetic feeling.In order to increase the bond strength of paint film and steel plate, all adopt the bonderizing of iron plate before spraying paint.Make the plate shell form a kind of similar honeycomb-like tissue, increase cohesive strength.But existing Phosphating Solution in use, and inhomogeneous at the phosphate coating that processing forms afterwards, phosphating time is long, and cohesive strength is little after the phosphatization.
Summary of the invention
For the defective that exists in the prior art, the object of the present invention is to provide the Phosphating Solution that a kind of phosphating time is short, phosphatization is effective.
For reaching above purpose, the technical scheme that the present invention takes is:
A kind of Phosphating Solution is comprised of following density component:
Mazhev salt 25-50g/L,
Zinc nitrate 50-80g/L,
Solvent is deionized water.
On the basis of such scheme, Phosphating Solution of the present invention is comprised of following density component:
Mazhev salt 35g/L
Zinc nitrate 60g/L
Solvent is deionized water.
Phosphating Solution of the present invention, prescription is simple, makes steel plate form uniform phosphate coating in the short time, forms beautiful paint film after the oven dry of spraying paint, and cohesive strength increases.
