Title:
ANTICORROSIVE FOR METAL PREVENTING FORMATION OF SCALE
Document Type and Number:
Japanese Patent JPS6056080
Kind Code:
A
Abstract:
PURPOSE: To obtain an anticorrosive for metal preventing the formation of scale in a cooling water system or the like by blending polyphosphoric acid and/ or orthophosphoric acid with a copolymer consisting of prescribed monomers and styrenesulfonic acid.
CONSTITUTION: The titled anticorrosive is composed of polyphosphoric acid and/ or orthophosphoric acid and a prescribed polymer. The polymer consists of 10W90wt% in total of maleic acid, maleic anhydride and a monomer having one or two carboxyl groups and 10W90wt% styrenesulfonic acid. The monomer having one or two carboxyl groups is represented by the formula (where each of R1W R4 is H, methyl or carboxyl, and one or two among R1WR4 are carboxyl).
