Water-based metal cutting liquid

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...

AI Technical Summary

Problems solved by technology

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, but it contains a certain amount of base oil, and some products also contain a certain amount of Chlorine-containing and phosphorus-containing extreme pressure additives; while emulsified cutting fluids have high base oil content, short service life, and troublesome follow-up treatment of waste fluids

[0003] Existing cutting fluids use boric acid, sodium nitrite, chlorinated paraffin, alkyl sulfonate, etc. in large quantities. Although these additives can provide good processing effects, they are carcinogens or produce carcinogens, which affect human fertility. Moreover, the cutting fluid containing sulfur, phosphorus, and chlorine is easy to be corrupted and smelly during use, has poor biodegradability, and the waste liquid is difficult to handle, which is harmful to the environment.
