Antirust agent composition and use thereof

The invention relates to an antirust agent composition, consisting of the following components: benzotriazole corrosion inhibitors, liquid alkyl phosphate amine salt wear-resistant antirust agents and optional base oil. The invention further relates to use of the antirust agent composition and food-grade lubricating oil containing the antirust agent composition. Compared with the existing food-grade antirust additives, the antirust agent composition provided by the invention has better antirust performance, can effectively perfect the defect that the existing antirust additive products have insufficient antirust function on lubricating oil with larger viscidity, meets the high-standard food grade requirements and can be used an effective food-grade lubricating oil additive. Meanwhile, the raw material source is extensive and the preparation process is simple and convenient, so that the application prospect is extensive.
