Problems solved by technology

[0011] Although this low-temperature-resistant lubricating oil for die-casting machines and its preparation method have enhanced the lubricating performance of the lubricating oil, it has also enhanced the wear resistance and corrosion resistance of the lubricating oil to a certain extent, but its wear resistance is insufficient. It is easy to be squeezed and damaged in a short time, thus reducing the overall lubrication effect

Embodiment Construction

[0032] A lubricating oil preparation method provided in this example includes the following steps, S1: Take the following raw materials by weight: 75-80 parts of base oil, 10-15 parts of compounding agent, 5 parts of viscous agent, and 1 part of pour point depressant , 3 parts of antifoaming agent, 1 part of tackifier;

[0033] S2: Use an ultrasonic stirrer to mix and stir the base oil and compounding agent, heat the mixed substance to 70°C, continue to stir until the kinematic viscosity and pour point reach the standard, and keep the overall temperature at 60-75°C;

[0034] S3, adding the pour point depressant and the viscous agent to the above mixture in turn, and mechanically stirring for 8 to 10 minutes until the mixture is fused;

[0035] S4: Add an antifoaming agent and a tackifier to the above mixture, and at the same time add 1 part of ultrafine metal powder, stir and fuse the mixture, raise the temperature to 80°C, and keep it warm for 40 minutes to obtain the finishe...

Abstract

The invention relates to a lubricating oil preparation method, and relates to the technical field of lubricating oil manufacturing. The preparation method comprises following steps: step one, preparing following raw materials in parts by weight: 75 to 80 parts of basic oil, 10 to 15 parts of complexing agent, 5 parts of viscous agent, 1 part of pour point reducer, 3 parts of antifoaming agent, and1 part of tackifier; step two, mixing and stirring the basic oil and the complexing agent by an ultrasonic stirrer, heating the mixture to a temperature of 70 DEG C, keeping on stirring until the kinematic viscosity and pour point reach the standards, and maintaining the temperature of the mixture in a range of 60 to 75 DEG C; step three, adding the pour point reducer and the viscous agent into the mixture in sequence, and mechanically stirring the mixture for 8 to 10 minutes until all substances are merged; and step four, adding the antifoaming agent and the tackifier into the mixture. The provided lubricating oil has a strong wear resistant performance, is not easily damaged by extrusion, and has a long service life. The situation that a user forgets to add lubricating oil and the automobile parts are damaged is avoided. Moreover, the using effect is better and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to a lubricating oil preparation method. Background technique [0002] As long as it is applied between two relatively moving objects and can reduce the friction and wear of the two objects due to the function of contact, it is a lubricating oil. Lubricating oil in a narrow sense 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 role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. . [0003] Lubricating oil is a technology-intensive product, which is a mixture of complex hydrocarbons, and its real performance is the combined effect of complex physical or chemical changes. The basic properties of lubricating oil include general physical and chemical properties, special physical and chemical properti...
