Problems solved by technology

[0003] The quality of lubricating oil can be divided into good and bad, and the quality difference is basically defined only by the selection of raw materials. If the raw material is selected well, the quality will be high. However, my country is currently in an era of relative energy shortage. Therefore, raw materials with good quality are very expensive. can't get people's favor

Abstract

The invention provides synthetic lubricating oil for an automobile and relates to the technical field of preparation of chemical raw materials. The synthetic lubricating oil is prepared from the following raw materials: 20-50 parts of herbal oil, 10-30 parts of mineral oil, 20-50 parts of animal oil, 1-3 parts of dodecenylsuccinic acid, 1-3 parts of molybdenum dialkyl dithiocarbamate, 2-5 parts of a methylic silicone fluid grease, 3-6 parts of polymethacrylate, 2-4 parts of magnesium sulfonate, 3-5 parts of butyl octyl diphenylamine, 10-13 parts of pentaerythritol and 7-15 parts of glyceride acrylate. The synthetic lubricating oil has the benefits as follows: the technological process is simple, raw materials are reasonably proportioned, the cost is low, raw materials are easy to obtain, animal and plant oil used in traditional lubricating oil is replaced, so that the cost is effectively reduced under the condition that the effect is not changed, and the synthetic lubricating oil is efficient, has high cost performance, a remarkable use effect and high market value and is convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of chemical raw material preparation, in particular to a synthetic lubricating oil used in automobiles and a preparation method thereof. Background technique [0002] Cars have completely entered people's lives. Cars have spread all over the world. When cars are in use, fuel oil and engine oil lubricants are used frequently; automotive lubricants are divided into mineral lubricants, synthetic lubricants, semi- Synthetic lubricating oil and other types are formulated from hydrocarbons extracted from natural gas and crude oil. There is no clear definition of synthetic oil in the world. Generally, lubricating oil containing PAO is called synthetic engine oil. Most of the commercially available products labeled as synthetic oil contain less than 12% PAO. Fully synthetic engine oil is formulated with 100% PAO as base oil and additives. [0003] The quality of lubricating oil can be divided into good and bad. Th...
