The invention discloses a lubricant, a fully synthetic cutting fluid containing the lubricant and a preparation method of the lubricant, and belongs to the technical field of fully synthetic cutting fluids, the lubricant provided by the invention is prepared from the following raw materials in parts by weight through esterification reaction: 10-75 parts of C21 binary acid and 25-90 parts of hydroxyl-containing raw materials, the hydroxyl-containing raw materials comprise polyethylene glycol with the molecular weight of 200-1500, trimethylolpropane, ricinoleic acid, pentaerythritol and polyalkylene glycol with the molecular weight of 800-5000, the lubricant has good lubricating performance and non-ferrous metal protection capacity, can coexist with a cation settling agent and is suitable for preparing a novel fully-synthetic cutting fluid, and further, the lubricant can be used for preparing the fully-synthetic cutting fluid. The lubricant can replace mineral oil or other lubricants and can be conveniently app
