Description

Hydraulic or Slide-way oil the same water-cutting fluids composition

The present invention relates to a manufacturing method for allowing the water-soluble cutting oil to be used in combination with non-aqueous lubricating oils, such as hydraulic oil and sliding surface oil, which are used as mechanical working lubricants in metal processing machines (hereinafter referred to as "factory machines").

More specifically, non-aqueous lubricating oil (hereinafter referred to as "non-aqueous lubricating oil"), such as hydraulic oil and sliding surface oil, which are used for the operation of a metal processing machine in the metal working process, is introduced into the soluble cutting oil to corrupt the soluble cutting oil. In addition, the water-soluble cutting oil flows into the non-aqueous lubricating oil and rots the non-aqueous lubricating oil, thereby replacing the soluble cutting oil or the non-aqueous lubricating oil due to the rot.

By providing a special functionality to the water-soluble cutting oil to be used as a non-aqueous lubricating oil, and relates to a method for producing a hydraulic hydraulic oil and a sliding surface oil combined water-soluble cutting oil composition does not show the corruption due to the inflow even if mutually introduced to each other.

Until now, metal-working machines have been used as non-water-soluble lubricants, such as hydraulic oil and sliding surface oil, and water-soluble cutting oils used as metal-working lubricants, respectively, as mechanical operating lubricants. However, many data have already shown that during operation of metalworking machines, non-aqueous lubricants and water-soluble cutting fluids are mixed together in some way.

In the manufacturing technology of industrial lubricants, non-aqueous lubricants such as hydraulic oil and sliding surface oil do not add anti-corrosive agents, and water-soluble cutting oils are amine-based, guanidine-based, phenol-based, formaldehyde-based, and salicylic acid-based oils to prevent corruption. We are continuously developing water-soluble cutting oils with excellent anti-corrosion properties by adding various anti-corrosive agents (biocide) such as, chitosan-based as a water-soluble cutting oil component.

Even if a water-soluble cutting oil having excellent anti-corruption is developed, it is possible to avoid the problem of the original effects without technically overcoming the effects of hydraulic oil or sliding oil in the water-soluble cutting oil or in the case of the water-soluble cutting oil in the hydraulic oil or the sliding oil. It is difficult to prevent.

In addition, in order to remove the non-aqueous lubricating oil introduced into the water-soluble cutting oil, a large amount of money is invested separately from the machine tool to separate the oil-water separator or the oil skimmer (belt, tube, wheel, coalescing type, electrostatic method, filter, thin film liquid recovery method), etc. To prevent corruption by installing related devices, it is also difficult to prevent corruption.

With the development of metal processing technology, the automation technology of metal processing machinery is also making rapid progress. According to such technology, the manufacturing technology of water-insoluble lubricant or water-soluble cutting oil is also rapidly developed and used.

Hydraulic hydraulic oil, sliding surface oil and water soluble cutting oil are used differently in metal processing machines for different purposes because of their lubricating properties and performance. In addition, in order to produce metal processed products smoothly, the metal processing machine operates smoothly and the metal processing process is performed only when the lubrication characteristics and performances are different from each other.

In other words, hydraulic oil and sliding surface oil must have load-bearing performance (static pressure lubrication, boundary lubricity, sliding surface lubricity, extreme pressure, etc.), and water-soluble cutting oils must satisfy workability and have excellent anti-corrosion and anti-corrosion properties.

However, during the metal working process, the water-soluble cutting oil flows into the water-soluble cutting oil due to leakage of oil while the water-soluble cutting oil circulates through the metal processing machine, and grows the microorganisms as food for the microorganisms, or the water-soluble cutting oil is insoluble. It is emulsification of the entire non-aqueous lubricating oil to enter the lubricating oil to promote the decay, and in case of problems such as deterioration of lubrication characteristics and performance, it is necessary to replace the non-aqueous lubricating oil or water-soluble cutting oil.

It is a technical problem of the present invention to impart special functionality to the water-soluble cutting oil so that it can be used as a non-aqueous lubricant.

Furthermore, in the metal working process, the water-soluble cutting oil combined with non-aqueous lubricants, such as hydraulic fluids and sliding surface oils used in metal processing machines and water-soluble cutting oils used for metal processing, is used as a new lubricant manufacturing technology. It is an invention that gives special function to water soluble cutting oil, and has processability, anti-corrosion property and rust prevention property as metal covalent oil, and water soluble cutting oil itself has the same load-resistance performance as non-water soluble lubricant (static pressure lubrication, boundary lubrication activity, sliding surface lubricity, Extreme pressure, etc.) so that it can be used as a water-insoluble lubricant

For the operation of metalworking machinery, it should be used as a mechanical operating lubricant.

The metal processing furnace can be used as a water-soluble cutting oil with excellent processability, anti-corrosion and anti-rusting properties, so that it can be used as a hydraulic oil and sliding surface oil combined water-soluble cutting oil composition that does not show the spoilage due to mixing even if introduced into each other.
