Boron-free chlorine-free formaldehyde-free microemulsified cutting fluid and application thereof

Abstract

The invention discloses a boron-free chlorine-free formaldehyde-free microemulsified cutting fluid and application thereof. The microemulsified cutting fluid is prepared from the following raw materials in percentage by mass: 30-60% of base oil, 1-5% of rust inhibitor, 0-5% of extreme pressure agent, 1.5-8% of bactericide, 3-15% of mixed base, 0-5% of coupling agent, 1-8% of anti-hard water agent, 1.2-5% of corrosion inhibitor, 5-20% of lubricant, 3-15% of anionic surfactant, 3-20% of emulsifier and the balance of water. The microemulsified cutting fluid disclosed by the invention has excellent lubricating properties, and can simultaneously satisfy multiple processing modes, including fraising, boring, tapping, threading, high-speed milling, hole drilling and the like. The microemulsified cutting fluid is especially suitable for processing electronic aluminum alloys. In addition, the microemulsified cutting fluid has the advantages of excellent defoaming property, excellent wettability, high raw liquor stability, high emulsifying stability, high biological stability, longer service life, lower consumption and lower cost.

Description

technical field [0001] The invention belongs to the field of metalworking fluids, and in particular relates to a boron-free, chlorine-free, and formaldehyde-free microemulsion cutting fluid and an application thereof. Background technique [0002] China is the world's largest manufacturer and second largest consumer of consumer electronics, and also the world's largest manufacturer of computers and parts. More than 60% of the world's computer parts are manufactured in Guangdong. In 2010, the global consumer electronics market was US$873 billion, with a global growth rate of 13% and a Chinese growth rate of 25%. The development of the electronic product manufacturing industry has also driven the demand for metalworking fluids, especially the development of electronic products towards weight reduction and portability, which has led to an increasing demand for cutting fluids for aluminum alloys. [0003] Since most of China's electronic products are exported to Europe and the ...

Problems solved by technology

[0008] At present, domestic aluminum alloy processing fluids generally use boric acid, chlorinated paraffin, and formaldehyde-releasing additives, which cannot meet the requirements of European and American environmental protection regulations when used in electronic product processing
