Abstract

The invention discloses an emulsified cutting fluid, a cutting diluent and preparation and application methods thereof. The emulsified cutting fluid is prepared from the following raw materials: 5-15% of distilled water, 3-10% of rust-inhibiting additive, 4-10% of triethanolamine, 4-10% of co-emulsifier, 3-10% of long-chain fatty acid, 2-3% of nonionic surfactant, 1-5% of coupling agent, 1-5% of hard water-inhibiting additive, 5-10% of extreme pressure additive, 40-60% of base oil, 1-2% of anticorrosion and bactericidal agent, 0.1-2% of copper-aluminum alloy protective agent and 0.5-1.0% of defoamer; the emulsified cutting fluid is stable in lubrication property, cleaning property and hard water resistance, and good in rust resistance. The emulsified cutting fluid does not contain chlorine, diamine, nitrite and other nitro compounds, and causes no pollution on the environment; besides, the emulsified cutting fluid has no pungent smell, the cut powder is easy to settle, and the service life of a cutter can be effectively prolonged.

Description

technical field [0001] The invention relates to an emulsified cutting fluid, a cutting diluent and methods for preparing and using the same. Background technique [0002] In the prior art, the emulsified cutting fluid should be diluted 20 to 30 times with industrial tap water before being used to prepare a working fluid. In order to ensure the stable performance of the machining fluid, each cutting fluid manufacturer has clear requirements on the hardness of the dilution water. It is generally required in the industry that the hardness of the dilution water should not exceed 500mg / L. [0003] my country's vast territory has formed different water quality conditions in various places. In many areas, due to the high hardness of the dilution water, the user needs to soften the industrial tap water first, and then it can be used as the dilution water of the emulsified cutting fluid after reaching the hardness requirement. This not only increases the production costs such as i...
