NOVELTY - Biolubricant composition comprises 18-22 pts. wt. polytrifluoropropylmethylsiloxane, 3-5 pts. wt. chitin, 8-12 pts. wt. fatty acid homopolymer ester, 1-2 pts. wt. nanoparticles, 2-5 pts. wt. oleic acid, 2-3 pts. wt. preservatives and 100-120 pts. wt. deionized water. USE - Used as biolubricant composition. ADVANTAGE - The composition avoids the problem that the lubricating medium in the prior art cannot be penetrated into the friction interface by pouring supply, the actual function of some lubricants is not obvious, in the process, the life of the lubricant after use is not good, the nanoparticles are modified with oleic acid and preservatives, combined with the biological properties of fatty acid homopolymer esters, so that the lubricant composition has better performance, the average reduction rate of flank wear is significantly reduced, the aggregation and sedimentation phenomenon of nanoparticles is changed through the dispersant, and improves the overall service life of the lubricant composition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the biolubricant composition, comprising (S1) mixing and stirring polytrifluoropropylmethylsiloxane and chitin, keeping the temperature at 35-40°C, keeping stirring for 30-45 minutes, adding fatty acid homopolymer ester, adjusting the temperature to 45-50°C, and stirring rapidly for 5-10 minutes to obtain mixture A, (S2) mixing nanoparticles, oleic acid and preservative, mixing at 30-45°C for 20-40 minutes, then drying to obtain particle B, and (S3) adding the particle B to the mixture A, then adding deionized water, and performing stirring and ultrasonic treatment in sequence to obtain biolubricant composition.
