Overview of lithium 12-hydroxystearate
Lithium-based (including complex lithium-based) grease is a new type of multi-effect grease with excellent performance. It is widely used in various fields such as automobiles, metallurgy, military industry, railways and bearings. It is the development of grease manufacturers. One of the mainstream products, with broad market prospects. At present, the output of lithium-based (including complex lithium-based) grease has exceeded 80% of China's total grease output. 12-Hydroxystearic acid is an important raw material for the production of lithium-based (including complex lithium-based) grease, and it is irreplaceable. The supply and resource status of 12-hydroxystearic acid play a vital role in the cost and production assurance of lithium-based (including complex lithium-based) grease.
12-Hydroxy Lithium Stearate Application
12-Hydroxystearic acid is an important raw material for the production of lithium-based (including complex lithium-based) grease. Examples of its application are as follows:
1) Prepare an oxidation-resistant engine lubricating oil. The lubricating oil includes the following components in parts by mass: 51-56 parts of base oil, 13-16 parts of polyethylene oxide, 5-7 parts of nano silica Parts, 5-9 parts of tricresol phosphate, 3-5 parts of alkyl diphenylamine, 1-3 parts of lithium 12-hydroxystearate, viscosity index improver OCP: 3-5 parts, polymethacrylate 2- 5 parts, 2-4 parts of dialkyl dithiophosphate, 2-5 parts of octylphenol, 4-7 parts of sulfonate detergent, 2-6 parts of di-n-butyl phosphite, 1 part of dimethyl silicone oil -3 parts, 1-3 parts of polyisobutylene succinate pentaerythritol ester, anti-foaming agent T901: 1-3 parts. The oxidation-resistant engine lubricating oil of the present invention is a high-performance engine lubricating oil specially designed for long-term operation of high-load diesel engines, complex working conditions, heavy thermal load, frequent replacement of diesel in different regions, and the like. It has extraordinary high-temperature detergency and dispersion performance, effectively preventing piston ring sticking and cylinder liner polishing caused by the use of fuel direct injection technology and maintaining the hair
2) Prepare a low-temperature grease, which includes mineral oil, synthetic oil, fatty acid soap, antioxidant, and rust inhibitor. Compared with the prior art, the present invention uses a semi-synthetic oil mixed with Class III oil and ester oil and/or PAO oil as the base oil. Class III oil has a higher viscosity index, excellent high and low temperature performance, and oxidation. Stability, thermal stability and evaporation performance, ester oil and PAO synthetic oil also have a higher viscosity index and excellent low temperature performance, while using lithium stearate and lithium 12-hydroxy stearate using lithium stearate and The mixture of lithium 12-hydroxystearate is a thickening agent to thicken the semi-synthetic oil, so that the low-temperature grease has good low-temperature performance, ensures the normal lubrication of the used parts at low temperatures, and has a wide range of applicable temperature. The thickener is simple to synthesize.
3) Prepare a lithium-based grease composition. A special high acid value mineral base oil is used for saponification to prepare lithium-based grease. Put the high acid value mineral base oil into the kettle, add 12-hydroxystearate 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. The lubricating grease of the present invention reasonably utilizes the existing domestic base oil resources, replaces the use of naphthenic acid raw materials, and significantly reduces the production cost of the lubricating grease. The lubricating grease of the present invention not only has good mechanical stability and colloidal stability, but also can effectively improve the friction and wear conditions during the operation of mechanical equipment and has good lubricating performance. The grease produced by the invention can be used for the lubrication of automobiles, engineering machinery and other mechanical equipment.
4) Preparation of a lubricating oil for electric motors, the lubricating oil comprising base oil, antioxidant, heptatenyl imidazolinenyl succinate, tricresol phosphate, alkyl naphthalene, methyl silicone oil, polycyclic Oxyethane and lithium 12-hydroxystearate; wherein the weight average molecular weight of the polyethylene oxide is 1000-3000, and the weight average molecular weight of the alkyl naphthalene is 2000-4000. The lubricating oil has excellent viscosity and kinematic viscosity index, and the pH of the lubricating oil is 6-8. At the same time, the method for preparing the lubricating oil is simple and the raw materials are easy to obtain.
