Research progress in preparation technology of green environmental anticorrosion coating on metal surface

Abstract

The metal surface anti-corrosion technology has always been the focus of attention in the field of industrial engineering. With the advancement of science and technology and the consideration of environmental protection, its green environmental protection requirements have gradually become one of the important indicators of the current metal surface anti-corrosion technology. In this paper, in order to study the research progress of green anti-corrosion coating technology on metal surface in recent years, based on a large number of domestic and foreign literatures, the classification, characteristics and application of membrane technology and anti-corrosion mechanism of three typical new technologies in metal surface anti-corrosion coating, i.e. self-assembled monolayers(SAMs) technology, corrosion inhibitor and molecular sieve membrane technology were reviewed. At the same time, other feasible green anti-corrosion coating technologies such as coating additives and graphene coatings and the developing trend of self-assembled monolayers, corrosion inhibitor and molecular sieve membrane technology in system construction, process optimization and composite coating design and etc are pointed out.
