CORROSION INHIBITOR FOR METAL AND METHOD OF CORROSION INHIBITING FOR METAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a metal corrosion inhibitor small in influence on the environment and also exhibiting excellent metal corrosion inhibiting effect.;SOLUTION: The corrosion inhibitor for metal contains an acrylic acid based copolymer with the weight average molecular weight of 2,000 to 15,000 obtained by copolymerizing the acrylic acid or the alkali metal salt or ammonium salt of acrylic acid by 50 to 90 wt.% and methyl acrylate by 10 to 50 wt.% as an effective component.;COPYRIGHT: (C)2001,JPO
