Technical Field

The invention relates to the field of preparation of cutting fluid, and particularly relates to cutting fluid and a preparation method thereof.

Background

The cutting fluid on the market at present has different problems in the using process due to the lack of formula technology, and if the cutting fluid is smelly, rusty, allergic and the like, a user finds that the problems can not be solved in time, and only needs to replace new fluid, so that the environmental pollution problems that waste fluid can not be discharged or illegally discharged and the like exist. With the increasing requirements of ecological environment, the environment-friendly cutting fluid in the industry has higher technical performance, and the cutting fluid has dual requirements on ecological environment and service performance, and aims to reduce or eliminate discharge.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the cutting fluid which has good heat dissipation and excellent cleaning effect, can be used for a long time, is stable and safe, and is environment-friendly by greatly reducing emission and the preparation method thereof.
