Problems solved by technology

However, the price of vegetable oil is higher than that of mineral oil due to the small output. Another disadvantage is that it is easy to wax at low temperature and the oxidation stability is not very good.

Abstract

A lubricating oil is prepared from, by weight, 52-60 parts of castor oil, 45-50 parts of diisooctyl sebacate, 3-4 parts of coconut oil amine polyoxyethylene ether, 4-5 parts of triethanolamine monododecyl phosphate, 2-3 parts of benzotriazol, 40-44 parts of trimethylolpropane trioleate, 6-7 parts of hexyldecanol, 3-4 parts of secondary alcohol ethoxylate, 5-6 parts of dodecanedioic acid and 2-3 parts of nanometer indium oxide. The lubricating oil is prepared by adding simultaneously various additives and nanometer powder are added to base oil composed of various raw materials through a special technology; and all components have very protruding synergism; and the lubricating oil has excellent comprehensive performances and especially has protruding tribological performance, a friction wearing test result shows that the friction coefficient is low, and an extreme pressure performance test result shows that the extreme pressure performance is high.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil for vehicles and a preparation method thereof. Background technique [0002] Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils are widely used and used in a large amount (about 95%), but in some applications, products formulated with synthetic base oils and bio-oil base oils must be used, thus making these two base oils develop rapidly. [0003] The chemical composition of mineral base oils includes high boiling point, high molecular weight hydrocarbons and non-hydrocarbon mixtures. Its composition is generally alkanes (straight chain, branched chain, multi-branched chain), naphthenes (monocyclic, bicyclic, polycyclic), aromatics (single-ring aromatics, polycyclic aromatics), cycloalkyl aromatics and oxygen-containing, nitrogen-containing , sulfur-containing ...
