Embodiment 1
[0030] A fully synthetic cutting fluid, by weight percentage, consists of the following components:
[0031] Water-soluble extreme pressure additive 5%, surfactant 5%, rust inhibitor 15%, lubricant 4%, co-solvent 20%, triazole corrosion inhibitor 5%, fungicide 1%, defoamer 0.1% , synthetic additives 2%, the balance is deionized water.
[0032] Among them: the water-soluble extreme pressure additive is thiourea, the surfactant is a mixture of trans-block polyether RPE1720 and trans-block polyether RPE1740, the lubricant is polyethylene glycol, the co-solvent is isononanoic acid, antirust The antifoaming agent is a mixture of boric acid, diethanolamine, and fatty acid compound antirust agent synthesized at high temperature. Ratio 1.8, synthesized at 60°C for 3 hours to prepare the synthesized additives.
