Universal cutting and grinding micro-emulsion without mineral oil

Abstract

The invention discloses a universal cutting and grinding micro-emulsion without mineral oil. The micro-emulsion comprises organic amine, an antirust agent, macromolecular self-emulsifying ester, a lubricating agent, a coupling agent, an extreme pressure agent, an corrosion inhibitor, a surface active agent, an anti-bacteria sterilizing agent, an antifoaming agent and water. The universal cutting and grinding micro-emulsion without mineral oil meets requirements for machining universalities, no mineral oil is contained, the micro-emulsion is high in cleanliness, super-high in creosote resistance, good in wettability, excellent in wear resistance and extreme pressure resistance and long in service life, and EHS requirements are met.

Description

technical field [0001] The invention belongs to a cutting and grinding processing fluid, in particular to a general-purpose microemulsion cutting and grinding processing fluid without mineral oil. Background technique [0002] Cutting fluid and grinding fluid are two common types of metalworking fluids. They are generally divided into three categories: emulsification, microemulsion (semi-synthetic), and full-synthesis. Each of the three categories has its own processing focus. [0003] Due to the high oil content, high lubricating composition, and sufficient oil film thickness, the emulsified type has a better processing effect on materials that require high lubricating extreme pressure performance, such as stainless steel and aluminum alloy. The shortcomings of common emulsified cutting fluids are also very obvious. The high content of mineral oil results in high chemical oxygen consumption COD, and it is difficult to treat the waste emulsion in the later stage; the cooling...

AI Technical Summary

Problems solved by technology

Machining companies also seek a machining fluid that satisfies a variety of processing materials and processes as much as possible, but the performance is often unbalanced. For example, a microemulsion cutting fluid can meet the general cutting and grinding of steel parts, but it is not suitable for the processing performance of aluminum alloys. Insufficient, insufficient lubrication and corrosion protection; an emulsified cutting fluid meets the boundary lubrication requirements of stainless steel and aluminum wheels, but the processing effect, service environment and life of grinding are poor
