Abstract

PURPOSE: To keep anticorrosive effect for a long time by the procedure in which an anticorrosive, e.g., a nitrite, a chromate, etc., is added to an aqueous system in contact with metal to form anticorrosive film on the surface of metal and then a polymer with COOH groups is added to the aqueous system.
CONSTITUTION: An anticorrosive, composed of an oxidative substance, e.g., a nitrite, a chromate, a molybdate, etc., or of a crystallized film-forming substance, e.g., a polyphosphate, a phosphonate, etc., is added to an aqueous system in contact with a metal to form an anticorrosive film on the surface of the metal, and then 10 to 1000 ppm, preferably 20 to 500 ppm, of one or more of polymers with COOH groups, having a polymerization degree of more than 5 and a molecular weight of less than 20000, preferably 1000 to 10000, e.g., the homopolymer of acrylic acid, etc., is added further to the aqueous system.
