High-performance antirust cutting fluid

Abstract

The invention discloses a high-performance antirust cutting fluid which comprises the following components in parts by weight: 10-15 parts of machine oil, 3-8 parts of thiophosphoric acid ester, 5-10 parts of antirust composition, 3-5 parts of bactericide, 1-2 parts of citric acid, 3-5 parts of sodium carbonate, 5-10 parts of emulsifier, and 20-30 parts of water. A working solution is a colorless transparent fluid, is free of nitrite, and facilitates environmental protection and human health; a 2-3% diluent can be used for common processing; a 4.5-5.5% diluent can be used for extreme pressure processing; an application scope is wide; oil mist is low; pungent odor does not exist; the single antirust time far exceeds a standard, and is greater than 220h; and the cutting fluid has excellent grinding settleability and excellent cooling, lubrication and cleaning properties.

Description

technical field [0001] The invention relates to a high-performance antirust cutting fluid. Background technique [0002] Cutting fluid is essential in metal cutting. Emulsified cutting fluid has good lubricating and cooling performance. In the past, metal cutting fluid used in cars, grinding and drilling machines has emulsified oil (containing aromatic hydrocarbons and alcohol harmful gases), which has poor rust resistance. , Poor permeability, odor, easy to deteriorate; transparent cutting fluid has excellent cooling and cleaning properties, long service life, the disadvantage is poor lubrication and rust resistance, and most of them contain chemical substances that damage human health and pollute the environment , Contain sodium nitrite, sodium pentachloride etc. as patent CN87101044A, pollute environment seriously, endanger the personal health of operator. With the enhancement of human awareness of environmental protection, the traditional oil-based cutting fluid has dev...
