Abstract

Antirust lubricating oil is disclosed. The lubricating oil includes, by weight, 65-80 parts of mineral oil, 12-16 parts of dicyclopentadiene, 7-13 parts of methacrolein, 5-9 parts of methacrylamide, 8-12 parts of 5-norbornene-2-methanol, 2-5 parts of calcium dobesilate, 1-4 parts of dolomite dust, 9-13 parts of ethopabate, 7-12 parts of sodium naphthalene-1-acetate, 5-10 parts of 5-hydroxytryptophan, 4-8 parts of zinc hypophosphite, 12-17 parts of 4-bromophenoxybenzene and 6-11 parts of acetazolamide. The lubricating oil has good antiwear, antirust and lubricating effects and a production process is simple.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to an antirust lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oil is widely used, accounting for more than 95%. However, in some special occasions, the application of mineral base oils is limited, and at this time, products of synthetic base oils and bio-oil base oils are required. [0003] Rust is a mixture of oxides and hydroxides formed on the metal surface due to the action of oxyge...
