Oxidization-resistant copper corrosion inhibitor used in circulating cooling water system

The invention relates to a corrosion inhibitor, in particular to an oxidization-resistant copper corrosion inhibitor used in a circulating cooling water system. The oxidization-resistant copper corrosion inhibitor is prepared by a copper corrosion inhibitor, an additive, a solvent and water; and experiments prove that the oxidization-resistant copper corrosion inhibitor can not only protect the corrosion of a copper material in the circulating cooling water system, but also reduce the decomposition of organic phosphates and polymer scale inhibitors by residual chlorine. The combination of the additive and the residual chlorine in the oxidization-resistant copper corrosion inhibitor can also improve the sterilization capacity of a circulating water system so as to reduce the treatment cost of a circulating water treatment system and improve a treatment effect.
