Description
Technical field
The present invention relates to a kind of metal conditioner, particularly a kind of phosphate-free metal surface treatment agent, this metal conditioner can substitute traditional phosphatization liquid metal conditioner metal product is handled.
Background technology
The traditional raising metallic surface sticking power and the conversion coating treating fluid of erosion resistance all contain chromic salt or phosphoric acid salt; Though can obtain satisfied effect; But along with the enhancing day by day of environmental protection consciousness and the continuous maturation of conversion film technical application, technology such as traditional phosphatization, chromaking will progressively be replaced by environment-friendly type conversion film technology.
Application is the anti-corrosion method of widespread use in the metal finishing.Coating Pretreatment is the requisite preliminary processes of application; Its effect is on protected metal works, to set up a transition film; Make and to combine more closely between inorganic metallic surface and organic coating; With raising metal works and paint film adhesion, thus the corrosion resistance of raising coating.
At present, at paint industry, metal products is the application of sheet material especially, adopts phosphating process to improve the sticking power of coating and metal usually.But there are a lot of problems in this technology, as: phosphatization liquid use temperature need reach 45 ~ 65 ℃, and energy consumption is high; Generate a large amount of sediments in the parkerizing process, not only wasted pharmaceutical chemicals but also increased and removed the workload of waste residue, as dealt with the quality that also can influence phosphatize phosphate coat improperly; Complex procedures, the production continuity is poor.Simultaneously, need to use a large amount of strong acid and highly basic in the scale removal process, increase the pollutant emission load.
For the contaminated solution problem, the phosphatization substitute technology is arisen at the historic moment.In the twentieth century later stage, the U.S., Europe and Japanese appropriate authority have been developed without phosphorus substitute products in succession.The phosphatization substitute products mainly are divided into two types of zirconium system and silane-based in the market.Wherein zirconium be treatment agent with the BonderiteNT-1 type nano ceramics treatment agent of Henkel KGaA (Henkel) company is representative, and mainly substituting traditional iron is phosphatization and Zinc phosphating.Zirconium is that treatment agent not only has environmental protection, energy-conservation, easy and simple to handle, advantage that phosphorization technology can not be substituted such as cost is low, and very easily supporting with follow-up various processing modes, such as dusting, electrophoresis, spraying paint etc., can handle the multiple base material on the workpiece simultaneously.But present most zirconiums are treatment agent has strict requirement to workpiece material and water quality, and there is the excessive corrosion phenomenon in the processing of part sheet material, and performance index such as sticking power have the space of further lifting.Seminar of Dalian Polytechnic University has has also researched and developed the application of such technology on cold rolled sheet, sees the metal conditioner patent: application number: 201010617760.9 publication numbers: CN102051611A.The present invention is exactly that pin makes improvements and optimizes.
