油溶性缓蚀剂的研究现状及发展趋势

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

防锈油脂是金属材料防腐的保护盾,缓蚀剂是调控金属防腐膜层的核心物质。综述了油溶性缓蚀剂的作用机理、典型特点及具体应用的研究现状,重点阐述了油溶性缓蚀剂在油类基体中的抗腐蚀机制,并结合我国工业生产用油溶性缓蚀剂,进一步对油溶性缓蚀剂的缓蚀机理和最佳缓蚀剂组合进行研究,有利于工业生产中缓蚀剂的选择,同时,环保型缓蚀剂也是缓蚀剂发展的重要方向。

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.
