Abstract

The invention relates to the field of metal cutting additives, in particular to a full synthetic cutting fluid. According to a technical scheme adopted by the invention, the full synthetic cutting fluid is composed of the following components by weight percentage: 5-10% of a water-soluble extreme pressure additive, 3-5% of a surfactant, 5-15% of a rust inhibitor, 4-8% of a lubricant, 5-20% of a cosolvent, 5-10% of a triazole corrosion inhibitor, 0.2-1% of a bactericide, 0.1-1% of a defoamer, 1-2% of a synthetic additive, and the balance deionized water. The full synthetic cutting fluid provided by the invention has the advantages of: strong anti-rust ability, good ability for preventing workpieces from oxidizing and rusting, a maximum three-month (indoor) short-term rust protection effectaccording to different storage conditions, and strong hard water adaptability and physicochemical stability at the same time.

Description

technical field [0001] The invention relates to the field of metal cutting additives, in particular to a fully synthetic cutting fluid. Background technique [0002] Cutting fluid generally refers to the working fluid used to remove the heat generated in the cutting area in time to reduce the cutting temperature, prolong the service life of the tool and improve the machining accuracy of the workpiece during the machining process of the material. It usually should have the functions of lubrication, cooling, cleaning and rust prevention. According to its chemical composition, cutting fluid can be divided into two categories: oil-based cutting fluid and water-based cutting fluid. Oil-based cutting fluids have better lubricating properties and poorer cooling effects. Compared with oil-based cutting fluid, water-based cutting fluid has relatively poor lubricating performance and better cooling effect. In recent years, due to the continuous emergence of advanced cutting machine...
