Abstract

The invention belongs to the field of metal processing and particularly relates to a lithium salt compound and a preparation method of the lithium salt compound. The invention discloses the lithium salt compound which is obtained through the reaction of an acid compound, diethanol amine and lithium hydroxide monohydrate. The lithium salt compound solves the technical problems that a metal working fluid is not environmentally friendly and the anti-rust property and the extreme pressure property are not excellent in the prior art. The provided lithium salt compound does not contain phosphorus, does not cause eutrophication of a water body, and reduces the cost for wastewater treatment of a user; in addition, the pH value of the compound is 8-9, most of bacteria do not grow within the pH range, then the service cycle of the lithium salt compound is prolonged, and the problems of injuries of the human body and corrosion of the machine caused by excessive low pH value are also avoided; and besides, the lithium salt compound has an excellent anti-rust property and an excellent extreme pressure property on the basis of environmental friendliness.

Description

technical field [0001] The invention belongs to the field of metal processing, in particular to a lithium salt compound and a preparation method thereof. Background technique [0002] Extreme pressure agent is a heavy-duty additive that forms an extreme-pressure lubricating film with the surface of friction pairs under extremely harsh conditions such as high temperature and high pressure. It is used for cutting and forming of difficult-to-machine materials, and is also used for harsh processing of various steels and irons. Processes such as drilling, tapping, cold heading, drawing, etc. [0003] Commonly used extreme pressure agents can be divided into the following two types according to their film-forming mechanism: they can directly react with the surface of the base metal to form a reaction film. These compounds are mainly: sulfur-containing (such as sulfurized fatty acid ester) or chlorine-containing ( Such as chloroalkane) compounds, active organic esters, metal sulfi...
