Research status and development trend of the corrosion inhibitor used in antirust oil of the metal

Corrosion-resistant oil is the protecting shield of the metal,and the corrosion inhibitor used in antirust oil of the metal is the core substance to regulate the anticorrosive film of the metal.The anticorrosion mechanism,typical features and the application research status of the corrosion inhibitor used in corrosion-resistant oil of the metal were summarized.The anticorrosion mechanism of oil-soluble corrosion inhibitor in the oil matrix was expounded.Combined with the commercial production situation of oil-soluble corrosion inhibitor in China,the anticorrosion mechanism of oil-soluble corrosion inhibitors and the optimal combination of corrosion inhibitors were studied,which favored to the choice of oil-soluble corrosion inhibitors during commercial production.The research on environmentally friendly corrosion inhibitors was also an important direction of corrosion inhibitor development.
