Preparation of the Phosphating Solution Modified with Organosilicon for the Steel

摘要

the anti-corrosion treatment to the steel metal with the O/W emulsion prepared by combining the organosilicon and phosphating solution not only safeguards the corrosion resisting properties of the steel surface but also promotes the bond strength between this phosphating film and the following coating.This paper discussed the preparation technologies and the construction processes of this O/W emulsion.Coating films was test by EIS and SEM,proved that the film had excellent anti-corrosion perfomences.
