Description
Technical field
The invention belongs to inorganic agent fields, and in particular to a kind of rare earth metal surface inorganic agent and preparation method thereof.
Background technology
Metal conditioner refers to the general name for the chemical agent that various processing are carried out to metal surface.Treatment of Metal Surface
Include the substrate pretreatments such as oil removing, derusting, phosphatization, antirust, prepare for metal coating techniques, metal protection technology,
Substrate pretreatment quality prepares hereafter coating and the use of metal has a great impact, and water soluble anti-rust agent therein is then solvable
Solution forms aqueous solution in water, and metal can prevent rust corrosion after the processing of this aqueous solution.
Currently, although traditional phosphate conversion and chromating process for treating surface can obtain good effect,
But it is right containing the carcinogens such as the heavy metal ion such as zinc, manganese, nickel, chromium and sub- environmental protection fluorine-free in the waste liquid being discharged in processing procedure
Environmental pollution is very serious, and metallic surface silanization treatment technology is not due to being related to environmentally hazardous substance, production technology energy
It consumes that low, technical applications are extensive, is considered being expected to the processing of substitution phosphate conversion and chromating processing, is metal surface
Individually protection latest development direction.
