Problems solved by technology

[0005] Therefore, the glycol-type water-soluble cutting fluid must be mixed with water in order to eliminate the ignition point. However, when the amount of water is small, there will be a problem of flammability, and when the amount of water is added, the dispersibility of the abrasive will deteriorate. cause problems
In addition, the glycol-type water-soluble cutting

Abstract

The present invention provides a nonflammable water-based cutting fluid composition which affords excellent dispersion property of abrasives, which does not cause problems involving in flammability upon the use for cutting process of a hard and brittle materials, which can be readily washed, and which can achieve sufficient rust preventive property even if it is used in an equipment for oil use. Provided by the present invention is a nonflammable water-based cutting fluid composition containing a polycarboxylic acid-based polymer compound and/or a salt thereof having a weight-average molecular weight of 1,000-200,000, and additionally a carboxylic acid and/or a salt thereof upon needs for a rust preventive property.

Description

technical field [0001] The present invention relates to a non-flammable water-based cutting fluid composition and a non-flammable water-based cutting fluid. More specifically, it relates to a water-based semiconductor crystal material monocrystalline silicon and polycrystalline silicon, quartz, crystal, ceramics, etc., which are suitable for crystal ingot cutting. The cutting fluid and the non-flammable water-based cutting fluid in the slurry form formed by mixing abrasives therein also relate to a non-flammable water-based cutting fluid composition and a non-flammable water-based cutting fluid used in oil-based equipment. Background technique [0002] Previously, in cutting fluids for cutting hard and brittle materials such as silicon ingots, non-aqueous cutting fluids with mineral oil as the main component were mainly used as abrasive dispersants. This non-aqueous cutting fluid is a slurry formed by dispersing abrasives such as silicon carbide in cutting oil at a ratio of ...
