Description
Technical field
The present invention relates to the crosslinked film that changes into of a kind of metal species chemical reaction, relate in particular to the chrome-free tanning agent that a kind of iron and steel, zine plate, aluminium and Al-alloy parts and zinc and zinc alloy are used.
Background technology
The coating film process, or claim membrane formation mechanism nothing more than two classes: the one, solvent evaporates coating drying and forming-film.Chemical reaction does not take place in it, is a kind of physical phenomenon.Example pyroxylin(e)finish and vinyl lacquer.Another kind of is by the crosslinked film that changes into of chemical reaction.
Realize that all metals avoid corrosion, prolong its work-ing life to greatest extent, this is to utilize approach of limited resources on the earth, and this is the universe's a common mission, and common is pursued.
Give metal and have optimum performance, go to greatest extent to satisfy that people use, the high request of the continuous proposition on the decoration, this is the far-reaching key subjects that are rich in the field of metal surface treatment technology, great task.
In view of the above, some developed countries, for example: Nihon Parkerizing Co., Ltd. etc. have just dropped into substantial contribution as far back as last century, manpower, material resources are furtherd investigate, exploitation, and all obtained corresponding achievement.
As everyone knows, which country environment protection has not been, and which geographic thing becomes the common serious social concern of paying close attention to and needing to solve jointly in the whole world.Coating Pretreatment waste water comprises degreasing, rust cleaning, table accent, phosphatization, passivation water and rinse water thereof, and often quantity discharged is big for they, and concentration is low, the composition complexity.Suspended substance is arranged, the tensio-active agent of difficult degradation, and phosphate radical, acid, alkali and heavy metal zinc, nickel, manganese, chromium plasma in the waste water.
Strict restriction has been done to the heavy metal ion in the waste water by some developed countries, does not allow to surpass 0.2～0.5ppm, particularly chromium element as nickel content in the German waste water and carries out strict control in waste discharge, example: do not allow to surpass 0.3mg/m in the European discharge water
3, Chrome-free (Cr in country that has even the proposal waste water
3+And Cr
6+), no COD, no BOD, no obnoxious flavour.Germany, Japan and other countries drop into the no nickel of research, Chrome-free pre-treatment product already.
Sodium Nitrite is universally acknowledged carcinogenic substance.Sodium Fluoride is a highly toxic substance, and potassium bichromate is easily polluted, and sulfuric acid, nitric acid, hydrochloric acid corrosion resistance are big.Because inferior sodium is cheap, the good promoter action of tool is still widely used on the pre-treatment industry again.But long-term contact, one or two people have seriously allergic.Eat several grams by mistake and constitute dangerous methemoglobinemia etc.The promotor that development, exploitation substitute the inferior sodium of carcinogens becomes important topic in the transnational metal finishing industry.
Summary of the invention
The technical issues that need to address of the present invention have provided the chrome-free tanning agent that a kind of iron and steel, zine plate, aluminium and Al-alloy parts and zinc and zinc alloy are used, and are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention is made of by mass percentage following raw material:
