Abstract

The invention relates to the field of corrosion prevention technology application, in particular to a high polymer (CTS-IA-AA) as well as preparation and application thereof in corrosion inhibition. According to the preparation method, an aqueous solution polymerization method is adopted, graft polymerization is conducted on IA and AA monomers on CTS in an aqueous solution under the action of an initiator to obtain a high polymer (CTS-IA-AA), wherein the initiator is a redox system (APS-SBS) and EDTA. The corrosion inhibitor CTS-IA-AA disclosed by the invention is low in preparation cost, green and pollution-free, can be quickly adsorbed on the surface of 304 stainless steel so as to weaken corrosion and oxygen absorption reaction on the surface of a material, has an obvious corrosion inhibition effect on the corrosion of the 304 stainless steel in a 3.5% NaCl solution, and provides a direction for protecting a metal material when a high polymer is applied to the corrosion inhibitor.

Description

technical field

[0001] The invention relates to the application field of anticorrosion technology, in particular to a high polymer (CTS-IA-AA), its preparation and its application in corrosion inhibition. Background technique

[0002] The 21st century is known as "a new era of marine development", but the harsh marine environment has caused great difficulties for the development of the ocean. The corrosion of metal materials is a common problem faced by the whole world, especially the corrosion in the ocean is quite serious, and the direct economic loss is huge. Therefore, on the basis of making full use of the existing anti-corrosion technology, we must actively strive to develop economical, efficient and environmentally friendly anti-corrosion technology, and carry out strict scientific management to reduce economic losses.

[0003] Corrosion protection technology mainly includes electrochemical protection technology to prevent corrosion, surface treatment technology, opt...
