Problems solved by technology

However, due to the high cost of oil-based cutting fluid and relatively serious pollution, water-based cutting fluid products with green and environmentally friendly properties are the development direction of cutting fluids. The source of water is rich, non-toxic and tasteless, and is an ideal green base fluid. The current commercially available water-based cutting fluids have unsatisfactory lubricity, antibacterial properties and permeability, which limits their application

Abstract

The invention discloses water-based metal cutting fluid with high antibacterial property. The water-based metal cutting fluid is prepared from the following components in parts by weight: 10-30 partsof base oil, 0.5-5 parts of synthetic fungicide, 5-12 parts of composite antirust agent, 6-13 parts of extreme pressure lubricant, 5-15 parts of fatty alcohol polyoxyethylene ether, 10-20 parts of sodium petroleum sulfonate, 0.2-2 parts of dimethyl silicone oil, 0.3-3 parts of fatty acid, 1-10 parts of oxirane cyclohexylamine, 3-10 parts of glycol ether and 10-40 parts of water. The water-based metal cutting fluid is good in lubricating property, high in permeability and excellent in antibacterial property.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a water-based metal cutting fluid with strong antibacterial properties. Background technique [0002] Metal cutting fluid is an important supporting material for cutting. The selection of suitable metal cutting fluid in metal cutting can play a good role in lubrication, cooling, cleaning and rust prevention, so as to improve tool durability, ensure processing quality and processing accuracy, improve production efficiency and reduce costs. The performance of cutting fluid depends on its composition, and cutting fluid is usually divided into two categories: non-water-soluble (oil-based) fluid and water-soluble (water-based) 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. However, due to the...
