[0018] Examples 1-3 and comparative examples
[0019] The preparation method of lithium-based grease containing nanoparticles, the specific steps are as follows:
[0020] (1). Weigh general lithium grease and nano-SiO 2 And nano MoS 2 ;
[0021]
[0022] (2) Additive dispersion treatment
[0023] Nanomaterials will slowly agglomerate after long-term storage, so they must be dispersed before use. 2 And nano MoS 2 Dispersion treatment: the nano SiO 2 And nano MoS 2 Add it to the beaker according to the mass ratio of 1:15 with absolute ethanol, stir evenly with a stirring rod, and 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 to the general lithium grease together with absolute ethanol, first use a blender to help nano-SiO 2 And nano MoS 2 Evenly diffuse into the general-purpose lithium-based grease, and then use the S65 three-roll grinder to grind the grease. ...
