Problems solved by technology

[0002] When cutting metal materials, the emulsified metalworking fluids traditionally used are gradually replaced by fully synthetic metalworking fluids due to the mature preparation process and good lubricating properties, but there are problems such as serious consumption of petroleum resources and difficult disposal of waste fluids.
Although there are fully synthetic metalworking fluids on the market at present, there are also many defects: first, the lubricating performance is average; second, nitrite and other substances harmful to the human body and the environment are added
These disadvantages restrict the promotion of products among users, especially high-end users

Abstract

The invention discloses a nano aqueous completely-synthetic environmental-friendly metal working fluid being composed of an organic acid, an organic amine, a corrosion inhibitor, a synthetic lubricant, a surfactant, water, a nano material and a defoaming agent. In the invention, a nano high-molecular lubricating raw material is employed for synthesizing the metal working fluid, so that the metal working fluid is greatly improved in lubricating performance (a laboratory test proves that a 5% diluted solution of the metal working fluid is not more than 0.03 in friction coefficient). The raw materials are free of harmful substances harming body health and environment safety so that the metal working fluid is greatly improved in safety and sanitation quality (a test proves that the metal working fluid is not less than 5000 g / kg in biological median lethal dose LD50, is not less than 5000 mg / m<3> in medial lethal concentration LC50 and is not higher than 1 grade in respiratory tract mucous membrane irritation).

Description

technical field [0001] The invention relates to a metalworking fluid. Background technique [0002] When cutting metal materials, the emulsified metalworking fluids traditionally used are gradually replaced by fully synthetic metalworking fluids due to the mature preparation process and good lubricating properties, but there are problems such as serious consumption of petroleum resources and difficult disposal of waste fluids. . Although there are fully synthetic metalworking fluids on the market at present, there are also many defects: one is that the lubricating performance is average; the other is that nitrite and other substances harmful to the human body and the environment have been added. These drawbacks have restricted the promotion of products among users, especially among high-end users. Contents of the invention [0003] The purpose of the present invention is to provide a nano water-based fully synthetic environment-friendly metalworking fluid with good lubri...
