Environment-friendly inactive vulcanized lard oil and preparation method thereof

Abstract

The invention relates to environment-friendly inactive vulcanized lard oil and a preparation method thereof. The preparation method comprises the steps of 1, respectively weighing all components; 2, filtering the weighed leaf fat for later use; 3, putting the weighed base oil into a kettle, pouring the filtered lard oil into the kettle, and heating while stirring until the temperature is raised to 120 DEG C; 4, slowly adding the weighed sulfur powder into the kettle while stirring, controlling the heating speed, stopping heating when the temperature rises to 140-150 DEG C, continuously heating to 180 DEG C after the sulfur powder is completely added into the kettle, stirring at the constant temperature of 180 DEG C after the sulfur powder is completely molten, and then stopping heating and starting cooling; 5, when the temperature of the mixture in the kettle is reduced to 120 DEG C, adding the weighed complex ester, keeping the temperature at 80-120 DEG C, and fully stirring; and 6, stopping stirring, standing, cooling, filtering out impurities through a filter sieve, cooling to normal temperature, barreling, and sealing. The obtained vulcanized lard oil is small in smell and strong in wear resistance and pressure reduction.

Description

technical field [0001] The invention relates to the field of vulcanized lard preparation, in particular to an environment-friendly inactive vulcanized lard and a preparation method thereof. Background technique [0002] Vulcanized lard is a dark brown, non-active vulcanized extreme pressure anti-wear agent with a general smell. It has the characteristics of high viscosity, good adhesion, thick oil film and high wear resistance. It is suitable as the main agent in metal plastic deformation process. It is suitable for blending high-end stamping oil and drawing oil; it is suitable for blending guide rail oil among industrial oils. The traditional craft is made by stirring pig suet with sulfur powder, heating and cooling down. [0003] The vulcanized lard produced by traditional crafts, due to the production of sulfides, makes the product have a strong smell, dark color, and a certain amount of odor pollution; with the development of industrial processing technology, the proces...

AI Technical Summary

Problems solved by technology

[0003]The vulcanized lard produced by traditional crafts produces sulfides during the production process, which makes the product smell strong, dark in color, and has certain odor pollution; with the development of industrial processing technology With the development of the industry, the difficulty of processing has been continuously improved, and the traditional vulcanized lard can no longer meet the needs of some high-load processing.
