Preparation and application of lithium 12-hydroxystearate

Overview of lithium 12-hydroxystearate

Lithium grease is made of natural fatty acid (stearic acid or 12-hydroxystearic acid) lithium soap, thickened medium viscosity mineral lubricating oil or synthetic lubricating oil, while synthetic lithium grease is made of synthetic fatty acid lithium soap, thickened medium Viscosity mineral lubricating oil or synthetic lubricating oil is made into mineral lubricating oil.

Lithium 12-hydroxystearate is a white powdery industrial product. It can be directly produced from 12-hydroxystearic acid and equimolar lithium hydroxide monohydrate at home and abroad. The domestic and foreign composite lithium technology has achieved rapid development in the 1990s and realized industrialized production. It is mainly composed of lithium salt containing C9～C10 dibasic acid, boric acid or salicylic acid and lithium 12-hydroxystearate, among which any two or three components are compounded to produce grease products.

A four-component lithium complex grease composition and preparation method: adding lithium 12-hydroxystearate, lithium azelate or lithium sebacate, lithium borate and lithium salicylate to base oil. The two-step saponification process is used to control the temperature and time of the one-step compound saponification, the temperature of the two-step alkali addition, the temperature and time of the compound co-crystallization, and the control of the maximum temperature. The four-component lithium compound has good adhesion performance and high temperature resistance. Leakage, high temperature bearing life, excellent comprehensive performance, can meet the high temperature environment equipment lubrication and high temperature centralized pumping lubrication. Lithium complex grease is a high-temperature grease with a dropping point of not less than 260°C. Its outstanding advantages are good adhesion, excellent high-temperature leakage resistance, and outstanding high-temperature bearing life at 160°C. Compared with polyurea grease, it has the advantage of not hardening at high temperature. Compared with ordinary two-component or three-component lithium complex, it has adhesion, excellent high-temperature anti-leakage performance, and outstanding high-temperature bearing life.

A lithium-based grease composition and a preparation method thereof: a special high-acid value mineral base oil is used for saponification to prepare a lithium-based grease. Put the high acid value mineral base oil into the kettle, add 12-hydroxy stearate lithium soap and lithium stearate soap, stir and heat up; when the temperature rises to 210~220℃, keep the temperature and stir for 1~5min; The base oil is put into the kettle to quickly cool the materials, and the additives are added when the temperature reaches 140-150°C; the stirring is evenly discharged out of the kettle; the finished product is obtained after grinding with a three-roll mill. Lubricating grease rationally utilizes domestic existing base oil resources to replace naphthenic acid raw materials, and significantly reduces the production cost of lubricating grease. Lubricating grease not only has good mechanical stability and colloidal stability, but also can effectively improve the friction and wear conditions of mechanical equipment during operation, and has good lubricating performance. The grease produced can be used for the lubrication of automobiles, engineering machinery and other mechanical equipment.

Application of lithium 12-hydroxystearate

Lithium 12-hydroxystearate grease is widely used in lubricants, stabilizers, decolorants and thickeners. Long-life general-purpose grease, which can replace calcium-based grease and sodium-based grease for bearing lubrication of aircraft, automobiles, tanks, machine tools and various mechanical equipment.
