Title:
MULTIFUNCTIONAL GROUP METAL CORROSION INHIBITOR, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/133875
Kind Code:
A1
Abstract:
Provided is a multifunctional group metal corrosion inhibitor, as shown in one or more of formula (I-a) to formula (I-c). The metal corrosion inhibitor is a multifunctional group metal corrosion inhibitor comprising Schiff base or a derivative structure thereof, a catechol group, and a mercapto group. A plurality of active functional groups are introduced, so that the active adsorption site of the inhibitor can be increased, and the synergistic effect of three functional groups can enhance the adsorption effect of the inhibitor and a metal, and thus, the inhibitor is suitable for adsorption of a plurality of metals. Therefore, the inhibitor can exert high anti-corrosion efficiency under the condition of a low addition amount, and provides a protection effect for the plurality of metals.
