Lubricating oil with modified additive and preparation method of lubricating oil

Abstract

The invention discloses lubricating oil with a modified additive and a preparation method of the lubricating oil, and particularly relates to the technical field of lubricating oil preparation, and the lubricating oil is prepared from the following raw materials in parts by weight: 73-85 parts of base oil, 8-15 parts of a complexing agent, 3-5 parts of a viscous agent, 1-3 parts of a pour point depressant, 1-3 parts of an anti-foaming agent and 1-3 parts of a tackifier. Employed auxiliary materials (in parts by weight) comprises 15 to 20 parts of dithioglycol and 17 to 25 parts of hexachlorocyclopentadiene. The anti-foaming agent and the tackifier are mixed with the base oil, so that the viscosity of the lubricating oil can be increased, the influence of temperature change on the viscosity of engine oil is reduced, the viscosity-temperature property of the engine oil is improved, the contact area of an oil product and air is reduced, and the oil product is prevented from being oxidized and deteriorated. Through the preparation of the oxidation liquid, the graphene is subjected to two times of oxidation treatment, and thus the graphene material can be directly applied to the field of lubrication. The lubricating oil has good bearing capacity and anti-wear and anti-friction capacity, the anti-friction performance of the lubricating oil is effectively improved, and the loss of an engine is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of lubricating oil preparation, in particular to a lubricating oil with modified additives and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. The lubricating performance of the engine is closely related to the safety, environmental protection and energy-saving performance of the car. With the continuous improvement of the engine performance, the requirements for lubrication are becoming more and more complex and demanding. In order to improve the lubricating performance of the engine, achieve wear reduction and energy saving, and improve mechanical efficiency. Oil additives also came into being. H...

Problems solved by technology

[0005] To this end, the embodiment of the present invention provides a lubricating oil with modified additives and its preparation method, through the mixing of compounding agent, viscous agent, pour point depressant, antifoaming agent and viscosifier with base oil, it can increase The viscosity of the lubricating oil can reduce the influence of temperature changes on the viscosity of the oil, improve the viscosity and temperature of the oil, thereby improving the pump efficiency when the oil is used, reducing energy consumption, increasing performance, delaying the speed of mechanical wear, and ensuring the use of the machine. and service life, reduce the contact area between oil and air, and prevent oil from oxidative deterioration. Through the production of oxidizing liquid, graphene is oxidized twice, so that graphene materials can have good dispersion and can be used As an excellent lubricating additive, it is directly applied to the lubrication field, avoiding the addition of dispersants, so that the lubricating oil prepared by mixing lubricating oil additives has good load-carrying and anti-wear and friction-reducing capabilities, effectively increasing the anti-friction performance of lubricating oil and Reduce the loss of the engine to solve the problem of poor lubricating effect of the lubricating oil in the prior art because the graphene additive is prone to stratification and precipitation during use
