NOVELTY - Preparation of anti-friction and wear-resistant lubricant, involves (i) preparing graphene solution, (ii) preparing graphene/titania sol, (iii) sintering graphene/titania sol at high temperature to obtain graphene/titanium dioxide nano-powder, and (iv) adding graphene/titanium dioxide nano-powder to liquid paraffin, and dispersing uniformly. USE - Preparation of anti-friction and wear-resistant lubricant. ADVANTAGE - The method greatly improves the anti-friction and anti-wear performance of the liquid paraffin under the high load condition. The lubricant is prepared by simple method at low cost without producing pollution to the environment.
