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 PAO9 into the fat making kettle, start the stirrer, heat up to 70℃, put in 5.0g 12-hydroxystearic acid, wait until the 12-hydroxystearic acid is completely dissolved, then add the lithium hydroxide pre-dissolved in water The solution (containing 0.2g of lithium hydroxide), the temperature is controlled at 130°C, and the reaction is carried out for 1 hour. After the saponification, 31.7g PAO9 was added, the temperature was controlled at 200°C, and the heating was stopped after 10 minutes. When the temperature drops to 190°C, add 31.7g PAO9, when the system cools down to 100°C, stop stirring, and grind uniformly with a three-roll machine to obtain lithium base grease 1.

[0037] Add 1.5g of α-zirconium phosphate sample to a 150mL round bottom flask, add 50mL of 0.05mol / L LiCl solution, stir at 50℃, reflux for 10 days, filter, wash with distilled water, and dry at room temperature to obtain LiZrPO ion Exchange type 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, in particular to a lubricating grease containing ion exchange type zirconium phosphate salt additives and a preparation method thereof. Background technique [0002] Grease is a semi-solid or semi-fluid product. It is a dispersion system formed by thickening a liquid lubricant with a thickening agent and has unique rheological properties. Due to its inherent excellent characteristics, lubricating grease not only meets general lubrication requirements, but also has extreme pressure, wear resistance and sealing requirements that conventional lubricating oils cannot achieve. It is widely used in various mechanical transmission and sliding parts. Solid lubricating additives are a very important type of additives in lubricating greases. When the lubricating film of the lubricating grease is subjected to high impact load, high heat, strong radiation, etc., it can play the role of extreme pres...
