Specifically, the present invention relates to an improved water-soluble abrasive composition that has excellent rust prevention and antifoaming properties, and is free from stickiness.

作用が懸念されるようになった。(Prior Art) Conventionally, water-soluble abrasives containing nitrites and alkanolamines as main components have often been used. This has been widely used for metal grinding because it lacks the grinding properties, anti-corrosion properties, and antifoaming properties required of an abrasive. However, in recent years, the formation of nitrosamines due to the reaction between nitrites and alkanolamines has been confirmed, and there has been concern about the carcinogenic effects of this.
このような情況下、近年、亜硝酸塩を含まない研削剤が

性及び消泡性は優れるが、液のベトッキ性があり研削作
業上支障をきたすと云う欠点がある。Under these circumstances, various nitrite-free abrasives have been proposed in recent years. For example, U.S. Patent No. 4.176.
Examples include those whose main component is a reaction product of alkanolamine and boric acid shown in No. 076. Although this has excellent rust prevention and antifoaming properties, it has the disadvantage that the liquid is sticky, which causes problems in grinding operations.

６５°Ｃの温度で４〜５時間両成分を反応させる。In the present invention, examples of the alkanolamine include ethanolamine (mono, di, and tri) and isopropanolamine (mono, di, and tri), but monoalkanolamine is particularly preferably used. That is, monoalkanolamine has superior antifoaming properties compared to di- or trialkanolamine. To obtain the reaction product of alkanolamine and boric acid, about 130 to 1
Both components are allowed to react for 4-5 hours at a temperature of 65°C.

施例に限定されるものではない。The present invention requires that glycols be used in combination with the reaction product of alkanolamine and boric acid. Glycols are water-soluble ones, and include ethylene glycol, propylene glycol, and other glycol derivatives, especially ethylene glycol,
Propylene glycol is preferably used. Commercially available products can be used as they are. The blending ratio of both components in the abrasive agent varies depending on the grinding conditions and the type of material to be cut, but for the reaction product of alkanolamine and boric acid, it is usually 5 to 40% by weight, preferably 15% by weight. ~35
% by weight, and for glycols (usually 5 to 2%)
0% by weight, preferably 7-15% by weight. In addition to these essential components, the abrasive of the present invention may optionally contain preservatives, antifoaming agents, anticorrosive agents, etc. (・0 Methods for preparing and using the abrasive of the present invention include There is no particular difference from the conventional case of water solubility and grindability. That is, an aqueous solution is prepared by dissolving essential components and optional components in water. This is diluted as appropriate (-). (Effects of the invention) The present invention The abrasive has not only good grinding properties but also excellent defoaming and rust prevention properties, and is not sticky and is extremely practical.The present invention will now be explained in more detail with examples. However, the present invention is not limited to the following examples unless it exceeds the gist thereof.
