Abstract

The invention relates to a lubricant, in particular to a metal cutting lubricant for use during cutting in machinery industry. The lubricant consists of 75 to 85% of mixture of boric acid, polyethylene glycol, fatty acid, diethylene glycol, triethylene glycol and palmitoleic acid, 0.5 to 1.8% of metal deactivator, 1 to 5% of antirust agent, 0.3 to 1% of antioxygen, 0.2 to 1.5% of extreme pressure additive and the balance of deionized water. The components are mixed according to weight percentage. The lubricant is highly efficient, environment-friendly and pollution-free and has no damage to metal surface, good cleaning, antirust and lubricating effects, no toxic effect, no odor and no corrosive effect on equipment.

Description

technical field [0001] The invention relates to a lubricating fluid, in particular to a metal cutting lubricating fluid suitable for cutting in machinery industry. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, chipping and grinding. Good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. It overcomes the shortcomings of traditional soap-based emulsions, which are easy to smell in summer, hard to dilute in winter, and poor anti-rust effect, and has no adverse effect on lathe paint. It is suitable for cutting and grinding of ferrous metals and is currently the most advanced grinding product. [0003] At present, the cutting fluids on the market may contain harmful chemical components. These chemical components will not only cause certain damage to the metal surface, but also cause certa...
