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: 22-32% of mineral oil, 2-10% of anionic surfactant, 1-5% of non-ionic surfactants, 1-3% of emulsion stabilizer, 5-10% of oiliness additives, 5-10% of extreme pressure additive, 5-15% of antirust additive, 0.5-3% of preservatives and bactericides, 0.1-0.3% of antifoam additive and the balance of water, wherein the total percent is 100%; the non-ionic surfactants are alkylphenol polyoxyethylene ether and / or fatty alcohol polyoxyethylene ether with EO (epoxyethane) number of 5-7; the preservatives and bactericides are Kathon and / or benzisothiazolin-one. The microemulsion cutting fluid and the diluent have excellent bacteria resistance, good lubricating properties and cooling properties and long service lives, dispense with replenishing bactericides and pH value improvers when in use, are environment-friendly and can provide good antirust properties for machined parts and 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...
