【発明の詳細な説明】 産業上の利用分野 本発明は、水晶を切削もしくは研磨する際に用いる液
組成物、特に、砥粒の分散性を改良した液組成物に関す
る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid composition used for cutting or polishing quartz, and more particularly to a liquid composition having improved dispersibility of abrasive grains.
従来技術と問題点 水晶を切削又は研磨する際に、従来、界面活性剤を少
量含有させた鉱油中にSiC（カーボランダム）、WC、Ti
C、アルミナ等から成る砥粒を分散させた液が用いられ
ている。Conventional technology and problems Conventionally, when cutting or polishing quartz, SiC (Carborundum), WC, Ti in mineral oil containing a small amount of surfactant
A liquid in which abrasive grains composed of C, alumina, etc. are dispersed is used.
しかし、上記分散液では、その中の砥粒粒子の比重が
大きいため、砥粒が沈降し易く、かつ再分散し難いの
で、その分散安定性が問題になる。特に、切削効率が良
い低粘度の鉱油を用いる場合、上記分散性が逆に低下
し、また、砥粒が一旦沈降すると液を攪拌しても再分散
が困難であるため、実用上の問題となつている。However, in the above-mentioned dispersion liquid, since the specific gravity of the abrasive grains therein is large, the abrasive grains are likely to settle and are difficult to re-disperse, so that the dispersion stability thereof becomes a problem. In particular, when a low-viscosity mineral oil with good cutting efficiency is used, the above-mentioned dispersibility decreases conversely, and once the abrasive grains settle, it is difficult to redisperse even if the liquid is agitated, which causes a practical problem. I'm running.
なお、分散性を高めるために、界面活性剤の含量を多
くすると、むしろ上記沈降層が固くなるので、循環ポン
プ等による再分散が困難となる。すなわち、上記沈降層
の柔らかさ保持と分散安定性を両立させることは実際上
非常に困難であるといえる。If the content of the surfactant is increased in order to improve the dispersibility, the sedimentation layer becomes rather hard, so that redispersion by a circulation pump or the like becomes difficult. That is, it can be said that it is actually very difficult to achieve both the softness retention and the dispersion stability of the sedimentation layer.
したがつて、水晶の切削液としては砥粒が沈降層を形
成し難く、仮に沈降しても攪拌等により容易に再分散す
ることが重要である。Therefore, it is important for the cutting fluid for the crystal that the abrasive grains are unlikely to form a sedimentation layer, and that even if sedimentation occurs, they are easily redispersed by stirring or the like.
発明が解決しようとする課題 本発明は、叙上の状況に鑑みなされたものであつて、
液中の砥粒の沈降が起りにくく、また、沈降して沈降層
を形成しても容易に再分散し得る、水晶の切削又は研磨
に用いるための水晶切削液組成物を提供することを課題
とする。Problem to be Solved by the Invention The present invention has been made in view of the above situation,
An object of the present invention is to provide a crystal cutting liquid composition for use in cutting or polishing a crystal, which is less likely to cause sedimentation of abrasive grains in the liquid, and which can be easily redispersed even if it sediments to form a sedimentation layer. And

晶切削面を清浄にする効果をも奏する。Of these additives, glycol monoalkyl ether and polyoxypropylene monoalkyl ether each have the effect of mainly improving the redispersibility of the sedimentation layer of the abrasive grains by adding 0.1 to 5% by weight to mineral oil. On the other hand, the polyoxyethylene alkylphenyl ether and sorbitan trioleate are mixed in the presence of at least one of the above compounds in an amount of 0.2 to 2% by weight to improve the redispersibility of the dispersibility of the abrasive grains. It also has the effect of cleaning the crystal cutting surface.
因に、これら添加剤の鉱油に対する配合量が上記範囲
より少ないと鉱油中の砥粒の良好な分散性がえられなく
なり、一方多くても一層の分散効果が期待できず、経済
的でない。Incidentally, if the amount of these additives to be mixed with the mineral oil is less than the above range, good dispersibility of the abrasive grains in the mineral oil cannot be obtained. On the other hand, if more than the above, a further dispersing effect cannot be expected and it is not economical.
以下実施例により、本発明及びその効果を具体的に説

評価した。結果は表１に示すとおりである。Example Carborundum (SiC) 30 was added to 100 parts by weight of mineral oil (B) composed of normal paraffin having a viscosity of 1.7 cSt (40 ° C.), and each additive was blended at the ratio shown in Table 1.
By mixing parts by weight and stirring with a stirrer to prepare a dispersion, each of which is injected into a graduated cylinder, the dispersibility of the abrasive grains is determined by the sedimentation velocity of the upper surface of the abrasive grain sedimentation layer, and the redispersibility of abrasive grains. The softness of the sedimented layer after standing for 24 hours was evaluated. The results are shown in Table 1.

著しく改善される。 As can be seen from Table 1, in the case of blending the specific compound according to the present invention, compared with the comparative example in which only the surfactant was blended without blending the glycol monoalkyl ether or the polyoxypropylene monoalkyl ether according to the present invention. Although the dispersibility of the abrasive grains remains almost unchanged, the redispersibility of the abrasive grains is significantly improved because the sedimentation layer becomes softer.

添加しても効果は小さいことが解る。On the other hand, in the samples No. 1 to No. 12 shown in Table 1, the results of evaluation of the cleanliness of the cut surface of the quartz crystal cut using each liquid in which 60% by weight of # 1000 carborundum was dispersed as the carborundum As shown in Table 1, No. 6, N
When coexisting glycol monoalkyl ether or polyoxypropylene monoalkyl ether with polyoxyethylene alkylphenyl ether and sorbitan trioleate like o.7 and No.8, it should be satisfied by the balance of these additives. The effect is obtained. On the other hand, as can be seen in Comparative Examples No. 9 and No. 10, it is understood that the effect is small even if a large amount of a slightly less polar synthetic ester or alkylbenzene is added.
