SCALE AND CORROSION INHIBITING COMPOSITION FOR PROTECTING SURFACES IN CONTACT WITH WATER AND METHOD FOR THE PREPARATION OF SAID COMPOSITION

摘要

Novel scale and corrosion inhibiting composition for protecting metal surfaces in contact with water. The composition is characterized by comprising a film-forming amine component, an alkalized amine component and an organic polysulfonic component whose molecule comprises at least two units of the structure (Io) in which A is a hydrogen atom or a C1-C4 alkyl group and X is a hydrogen atom, a Na+, K+ or NH4+ cation or a C1-C4 alkyl group. The invention also provides a method for the preparation of said composition.
