Towel gourd extract copper corrosion inhibitor and application method thereof

Abstract

The invention belongs to the technical field of corrosion inhibitors, and particularly relates to a towel gourd extract copper corrosion inhibitor and an application method thereof. The towel gourd extract is adopted as the copper corrosion inhibitor, the corrosion inhibitor is dissolved in a sulfuric acid solution, and a copper acid pickling solution with the towel gourd extract as the corrosion inhibitor is prepared. The towel gourd leaf extract has good solubility in a sulfuric acid environment, the towel gourd leaf extract can form a uniform and compact protective film on the copper surface, the towel gourd leaf extract is adopted as a copper corrosion inhibitor, and the corrosion inhibition efficiency can reach 91.3%.

Description

technical field [0001] The invention belongs to the technical field of corrosion inhibitors, in particular to a copper corrosion inhibitor of loofah extract and its application method Background technique [0002] Copper has played an important role in the process of human industrial civilization. From ancient civilization to the rapidly developing modern civilization, metal copper has made outstanding contributions in many aspects. This is because copper has good thermal conductivity, ductility and relative corrosion resistance. However, during long-term use, metal copper will be damaged to varying degrees due to the complexity of the use environment. Therefore, in order to effectively inhibit the corrosion of copper, corrosion inhibitors are usually used to protect the copper substrate from corrosion during the pickling process. [0003] Corrosion inhibitors usually contain heteroatoms such as N, S, O, P, and some unsaturated functional groups. These characteristics of ...
