Abstract

The invention discloses a water-based metal cutting liquid. The water-based metal cutting liquid is prepared from raw materials in percentage by mass as follows: 2%-7% of an antirust agent, 0.2%-2% of a corrosion inhibitor, 10%-20% of organic alkali, 20%-45% of an oleate lubricant, 2%-7% of amide, 2%-6% of an emulsifier, 4%-9% of an oiliness agent, 0%-5% of a coupling agent, 0%-3% of a softener, 1%-5% of a sterilizing agent, 0.1%-2% of a defoaming agent and the balance of water. The water-based metal cutting liquid provided by the invention contains no sulfur, phosphorus, chlorine or boric acid and is efficient, environment-friendly and recyclable.

Description

technical field [0001] The invention belongs to the field of machining cooling and lubrication, and relates to a metal cutting fluid, in particular to a water-based metal cutting fluid used in the metal cutting process. Background technique [0002] Traditional metalworking fluids mainly include cutting oil and cutting fluid. Cutting oil is mainly formulated from base oil and various sulfur-, phosphorus- and chlorine-containing extreme pressure additives. It has good lubricating and anti-rust effects, but has poor cooling and cleaning properties. During use, the oil mist is large, causing great environmental pollution and potential fire risks. . Cutting fluid is mainly divided into three types: fully synthetic, semi-synthetic, and emulsion. Fully synthetic cutting fluid has good cooling effect, but poor lubricating effect, and is mainly used in light-load processing occasions; semi-synthetic cutting fluid can take into account lubrication, cooling, and anti-rust effects, b...
