Problems solved by technology

However, since molybdenum is a non-renewable and scarce resource, the cost of use will increase year by year. Graphite must be in the presence of water vapor to exert the best lubrication effect, and the tightness of the grease makes it difficult to achieve the best use state; At the same time, both molybdenum disulfide and graphite are black substances, which also limit their application range to a certain extent.

Embodiment 1

[0036] Pour 31.7g of PAO9 into the fat-making kettle, start the agitator, heat up to 70°C, put in 5.0g of 12-hydroxystearic acid, wait until the 12-hydroxystearic acid is completely dissolved, then add lithium hydroxide dissolved in water in advance solution (containing 0.2 g of lithium hydroxide), the temperature was controlled at 130° C., and the reaction was carried out for 1 h. After saponification, add 31.7g PAO9, control the temperature at 200°C, and stop heating after 10min. When the temperature dropped to 190°C, 31.7g of PAO9 was added, and when the temperature of the system dropped to 100°C, the stirring was stopped, and the lithium-based base grease 1 was obtained after grinding evenly with a three-roll machine.

[0037] Add 1.5g of α-zirconium phosphate sample to a 150mL round bottom flask, add 50mL of 0.05mol / L LiCl solution, stir and reflux at 50°C for 10 days, filter, wash with distilled water, and dry at room temperature to obtain LiZrPO ions Exchangeable zirco...

Embodiment 2

[0041] Add 23.3g of 100SN into the fat-making kettle, start the agitator, heat up to 80°C, put in 30.0g of stearic acid, wait until the stearic acid is completely dissolved, then add the lithium hydroxide solution (containing lithium hydroxide 3.0 g), the temperature was controlled at 120° C., and the reaction was carried out for 5 hours. Add 23.3g of 100SN after saponification, and control the temperature at 220°C for 10 minutes, then stop heating. When the temperature drops to 160°C, add 23.3g of 100SN, and when the temperature of the system drops to 100°C, stop stirring, grind evenly with a three-roller machine to obtain lithium-based base grease 2.

[0042] Add 2.0g of α-zirconium phosphate sample to a 150mL round bottom flask, add 50mL of 0.45mol / L NaCl solution, stir at 70°C, reflux for 0.1 day, filter, wash with distilled water, and dry at room temperature to obtain NaZrPO ions Exchangeable zirconium phosphate material.

Abstract

The invention provides lubricating grease containing an ion-exchange-type zirconium phosphate additive. The lubricating grease comprises the following components in parts by weight: 100.0 parts of basic lubricating grease, 1.0-10.0 parts of ion-exchange-type zirconium phosphate material, 0.05-5.0 parts of antioxidant and 0-6.0 parts of antirust agent. A preparation method of the lubricating grease comprises the following steps of: stirring and mixing the basic lubricating grease, the ion-exchange-type zirconium phosphate material and the antioxidant for 1-10 hours in the range from a room temperature to 20 DEG C, grinding and homogenizing for 0.5-3 hours by using a three-roller machine or a high-voltage homogenizer, and uniformizing the mixture to prepare the lubricating grease product. The lubricating grease containing an ion-exchange-type zirconium phosphate additive has good anti-wear and friction reducing property at extreme pressure.

Description

technical field [0001] The invention belongs to a lubricating grease and a preparation method thereof, in particular to a lubricating grease containing an ion-exchange type zirconium phosphate additive and a preparation method thereof. Background technique [0002] Grease is a semi-solid or semi-fluid product, a dispersion system formed by thickening a liquid lubricant with a thickener, and has unique rheological properties. Due to its inherent excellent characteristics, grease can not only meet general lubrication requirements, but also has extreme pressure, wear resistance and sealing requirements that conventional lubricants cannot meet, and is widely used in transmission and sliding parts of various machinery. Solid lubricating additives are a very important class of additives in lubricating greases, which can play the role of extreme pressure, anti-wear and reinforcement when the lubricating film of the lubricating grease is subjected to high impact loads, high heat, st...
