Abstract

The invention discloses microemulsion cutting fluid, a cutting diluent and preparation and application methods of the microemulsion cutting fluid. The microemulsion cutting fluid comprises the following raw materials: 40-60% of mineral oil, 2-10% of anionic surfactant, 1-5% of non-ionic surfactant, 5-10% of emulsion stabilizer, 5-10% of oiliness additive, 5-10% of extreme pressure additive, 5-27% of antirust additive, 0.5-3% of preservative and bactericide, 0.1-0.3% of antifoam additives and 2-6% of water, wherein the antifoam additives include emulsified silicone oil and polyether modified organic silicon in a weight ratio of (1 to 1)-(1 to 2). The microemulsion cutting fluid and the microemulsion cutting diluent have excellent antifoam properties, good lubricating properties and cooling properties, good pH value stability, strong antibacterial activities and long service lives, can provide good antirust properties for machined parts and can greatly improve the machining precision of the machined parts.

Description

technical field [0001] The invention relates to a microemulsified cutting fluid, a cutting diluent and methods for preparing and using the same. Background technique [0002] According to the chemical composition of oil, cutting fluid is 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. Slow cutting requires the lubricity of the cutting fluid to be strong. Generally speaking, cutting oil is used when the cutting speed is lower than 30m / min. [0003] Cutting oils containing extreme pressure additives are effective for cutting any material when the cutting speed does not exceed 60m / min. During high-speed cutting, due to the large heat generation and the poor heat transfer effect of oil-based cutting f...
