Description
Technical field
The present invention relates to a kind of oil removal phosphating solution and preparation method thereof.
Background technology
Phosphatization is conventional pretreatment technology, principle should belong to chemical conversion film and process, be mainly used in steel surface phosphatization, and non-ferrous metal (such as aluminum, zinc) part also can apply phosphatization.Phosphatization is the process that a kind of chemistry and electrochemical reaction form phosphate chemical conversion film, and the phosphate conversion film formed is referred to as phosphating coat.The purpose of phosphatization is mainly: provides protection to parent metal, prevents metal to be corroded to a certain extent；For front bottoming of painting, improve adhesive force and the anti-corrosion capability of paint film layer；Antifriction lubrication is played in metal cold machining process.Parkerizing process includes chemistry and electrochemical reaction.Different phosphatization systems, different substrate materials phosphating reaction mechanism more complicated.Although scientist has done excessive quantifier elimination the most, but understands the most completely.After World War II terminates, phosphorization technology seldom has a breakthrough, the steadiest development and perfect.Phosphatization is widely used in anticorrosive technique, metal cold deformation processing industry.This, phosphorization treatment technology important improvement mainly had in period: the method for low temperature phosphor, various control phosphating coat film weight, steel tape high speed phosphatization.Currently, the research direction in phosphorization technology field is mainly carried out around raising quality, minimizing environmental pollution, the saving energy.In metal works once immerses the dilute phosphoric acid solution of heating, a tunic will be generated.And affect at least pH value of Phosphating Solution performance, free acidity, total acidity, phosphatization temperature, phosphating time, accelerator, rust cleaning, oil removing, table tune effect and metalline etc..Generally, bonderizing requires that surface of the work should be clean metal surface (two-in-one, three-in-one, four-in-one exception).Workpiece must carry out the pretreatment such as oil removing fat, corrosion thing, oxide skin and surface adjustment before phosphatization.Particularly before japanning, bottoming phosphatization also requires that making surface adjusts, metal surface is made to possess certain " active ", and form in picturesque disorder unit cell substrate, uniform, careful, closely knit phosphating coat could be obtained, reach to improve paint film adhesion and the requirement of corrosion resistance.Therefore, phosphatization pre-treatment is the basis obtaining high-quality phosphating coat.At present, what the use of domestic and international bonderizing was more is low temperature, middle temperature, high temperature phosphorization, and not only energy consumption is big, process process time length and sediment is many, and before phosphatization, need degreasing and rust removal, need after phosphatization to carry out sealing treatment, make phosphorization treatment process complicate, increase phosphatization cost, be unfavorable for that present metaplasia is produced.Therefore to adapt to fast-developing market competition needs, improve the quality of Phosphating Solution, it is achieved room temperature quickly forms phosphating coat, reduce energy consumption cost, technical process simplification, functionalization etc. become current development trend, therefore develop the oil removal phosphating agent with multifunction.But oil removal phosphating agent the most on the market is that (energy consumption is high, pollute weight by strong basicity hot solution, processed part is caused secondary oil to pollute by the oil slick on working solution surface), or with strong acid, or with organic solvent inflammable, explosive, virulent, produce the toxic deep-etching heavily contaminated of the gas, liquid, solid three wastes.To this end, we set about from formula and the technique of product, it is provided that a kind of oil removal phosphating solution and preparation method thereof.
Summary of the invention
It is an object of the invention to provide a kind of oil removal phosphating solution and preparation method thereof.
To achieve these goals; the invention provides a kind of oil removal phosphating solution, the raw material of following weight portion prepare: oxammonium sulfate. 3-6 part, sodium alklyarylsulfonate 2-5 part, hexamethylenetetramine 1-6 part, zinc dihydrogen phosphate 12-16 part, N-((phosphonomethyl)) glycine isopropyl amine salt 12-15 part, sodium lauryl sulphate 6-9 part, carboxymethyl starch sodium 2-4 part, linolenic acid 10-14 part, dinitropentamethylenetetramine 3-6 part, water 40-60 part, Sodium fluoroborate 15-17 part.
