Embodiment Construction

[0018] Embodiment 1-3 and comparative example

[0019] The preparation method of the lithium base lubricating grease containing nanoparticle, concrete steps are as follows:

[0020] (1) Weigh the general-purpose lithium-based grease and nano-SiO with the proportions shown in the table below 2 and nano-MoS 2 ;

[0021]

[0022] (2), additive dispersion treatment

[0023] Nanomaterials will slowly agglomerate after long-term storage, so dispersion treatment should be carried out before use, and nano-SiO 2 and nano-MoS 2 Dispersion treatment: the nano-SiO 2 and nano-MoS 2 Add it into the beaker with absolute ethanol according to the mass ratio of 1:15, stir evenly with a stirring rod, put it into an ultrasonic cleaner for 8min ultrasonic treatment.

[0024] (3), for nano-SiO 2 and nano-MoS 2 After the dispersion treatment, the nano-SiO 2 and nano-MoS 2 Add it together with absolute ethanol to the general-purpose lithium-based grease, first use a mixer to help nano-S...

Abstract

The invention belongs to the technical field of lubricant preparation, and particularly relates to lithium-based lubricating grease containing nano-particles and a preparation method thereof. The lithium-based lubricating grease containing the nano-particles is prepared from, by weight, 97%-99% of general lithium-based lubricating grease, 0.5%-1.5% of nano SiO2 and 0.5%-1.5% of nano MoS2. The preparation method comprises the steps that the general lithium-based lubricating grease, the nano SiO2 and the nano MoS2 are weighed by weight; the nano SiO2 and the nano MoS2 are ultrasonically dispersed into ethyl alcohol; the dispersed nano SiO2 and nano MoS2 and the ethyl alcohol are together added into the general lithium-based lubricating grease, even mixing is performed, and then the finished product is obtained. According to the lithium-based lubricating grease containing the nano-particles and the preparation method thereof, the general lithium-based lubricating grease serves as a criterion, the nano SiO2 and the nano MoS2 particles are added, and therefore the lubricating grease obtained through modification is better in wear resistance and higher in carrying capacity.

Description

technical field [0001] The invention belongs to the technical field of lubricant preparation, and in particular relates to a lithium-based lubricating grease containing nanoparticles and a preparation method thereof. Background technique [0002] Grease is a semi-solid or semi-fluid product, a dispersion system formed by thickening base oil 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, strong radiation, etc. In pr...
