Embodiment 1
[0061] A preparation method of a nano-carbon ball composite additive based on surface modification, comprising the following steps:
[0062] 1 g of acidified carbon nanospheres was added to 60 g of ricinoleic acid, and 0.09 g of catalyst zinc oxide was added. The reaction was carried out at 200° C. under vacuum conditions for 10 hours; after the reaction, it was naturally cooled, and after ultrasonic dispersion at room temperature for 15 minutes, the surface-modified nano-carbon material-ricinoleic acid composite anti-wear additive was obtained.
Embodiment 2
[0064] A method for preparing a carbon nanotube composite additive based on surface modification, comprising the following steps:
[0065] 1 g of acidified carbon nanotubes were added to 60 g of ricinoleic acid, and 0.09 g of catalyst zinc oxide was added. The reaction was carried out at 200° C. under vacuum conditions for 10 hours; after the reaction was completed, it was naturally cooled, and after ultrasonic dispersion at room temperature for 15 minutes, the surface-modified carbon nanotube-ricinoleic acid composite antiwear additive was obtained.
Embodiment 3
[0067] A preparation method of a graphene oxide composite additive based on surface modification, comprising the steps:
[0068] 1 g of acidified graphene oxide was added to 60 g of ricinoleic acid, and 0.09 g of catalyst zinc oxide was added. The reaction was carried out at 200° C. under vacuum conditions for 10 hours; after the reaction, it was naturally cooled, and after ultrasonic dispersion at room temperature for 15 minutes, the surface-modified graphene oxide-ricinoleic acid composite anti-wear additive was obtained.
