Problems solved by technology

[0003] At present, the emulsified oil or coolant routinely used in the market has at least the following defects: the emulsified liquid has poor anti-rust performance, not only contains toxic and harmful ingredients such as sodium nitrite, but also has a short service life; in the case of high temperature and high humidity in summer, It is easy to be corrupted and deteriorated, which greatly reduces the efficiency in actual production and application
[0004] For all kinds of steel products in the metallurgical industry, rolling oil is generally used in the process of hot rolling, cooling and rolling various stainless steel pipes and plates, and the pipes and plates rolled with oil are generally coated on the surface of the material. There is a layer of grease left on the surface, and the removal of the grease is usually cleaned with lye and then dried, which not only increases the production cost, but also seriously pollutes the environment

Abstract

A process for preparing lubricating-cooling liquid is prepared from borax, biethanolamine or triethanolamine, silica oil, sodium petrosulfonate, boric acid, decanedioic acid, heptanoic acid or octanoic acid, phenyltriazole, and oleic acid. Its advantages are high performance and no pollution.

Description

Technical field: [0001] The invention relates to a metal working fluid, in particular to a production process of a lubricating cooling fluid. Background technique: [0002] At present, with the development of modern machining in the direction of high speed, strength and precision, the development of hard-to-machine materials such as super-hard and super-strength makes cutting more and more difficult. Due to these two reasons, the friction force and friction heat in the cutting process are greatly increased, which requires metalworking fluids to have better lubrication, cooling, cleaning, and anti-rust properties to obtain an ideal machined surface. [0003] At present, the emulsified oil or coolant routinely used in the market has at least the following defects: the emulsion has poor antirust performance, not only contains toxic and harmful ingredients such as sodium nitrite, but also has a short service life; in the case of high temperature and high humidity in summer, It ...
