Problems solved by technology

Standing for rapid cooling, the resulting soap fibers are smaller and have a larger specific surface area, so the grease has a thicker consistency and less oil separation, but its mechanical stability is poor

Abstract

The invention provides a formula and a production process of lithium-based lubricating grease and relates to the technical field of lubricating grease. The production process comprises the steps of adequately mixing 1 / 3 of base oil with hydrogenated castor oil, lithium 12-hydroxystearate soap and lithium hydroxide soap, saponifying the mixture with equivalent lithium hydroxide to basically form a soap-oil sol state, adding 1 / 3 of base oil, further heating to the highest refining temperature so that the a soap-oil system in a grease preparation kettle is in a complete true solution state, cooling a drum cooler from a phase inversion temperature to 38-65 DEG C within several seconds by taking the rest 1 / 3 of base oil as snap-chilling mixed oil, and carrying out grinding, homogenization and degasification so as to obtain the lithium-based lubricating grease. The formula is scientific and reasonable; furthermore, by virtue of the scientific and simple production process, the degasification conversion rate can reach above 99.5%; and the produced products are all superior to general lithium-based lubricating grease products.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a formula of lithium-based lubricating grease and a production process thereof. Background technique [0002] Lithium-based grease is made from natural fatty acid (stearic acid or 12-hydroxystearic acid) lithium soap, thickened medium viscosity mineral oil or synthetic lubricating oil, while synthetic lithium-based grease is made from synthetic fatty acid lithium soap , Thickened medium viscosity mineral oil made. [0003] In the process of producing lubricating grease in an atmospheric kettle, there are many factors that affect the effect of saponification reaction, such as reaction temperature, concentration of reactants, reaction time, feeding sequence, contact between reactants, speed of mechanical stirring, alkali substances The concentration of the oil, the composition of the fat or fatty acid, and the composition of the base oil. Due to the limitation of t...
