本発明は親油性微粉末の水溶系懸濁液の製造方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing an aqueous suspension of lipophilic fine powder.
微細な固体粉末を各種の液体中へ分散させる方法は染料
工業、塗料工業および窯業等の分野で広く利用されてい
る。Methods of dispersing fine solid powders into various liquids are widely used in fields such as the dye industry, paint industry, and ceramic industry.
微細粒子が無極性（親油性）である場合にはオイル等の
無極性液体への分散が可能であり、微細粒子が極性（親
水性）である場合には極性液体への分散が可能であるこ
とは衆知の事実である。If the fine particles are nonpolar (lipophilic), they can be dispersed in nonpolar liquids such as oil, and if the fine particles are polar (hydrophilic), they can be dispersed in polar liquids. This is a well-known fact.

性剤を溶解して攪拌によって親油性微粉末を分散させる
方法が一般的である。However, it is impossible to disperse nonpolar fine particles in water, which is a polar solvent, and a surfactant must be used for this purpose. Therefore, a common method is to dissolve a surfactant in water in advance and disperse the lipophilic fine powder by stirring.
しかし、この方法如よると一旦親油性微粉末が界面活性
剤によって分散しても、界面活性剤の親油性微粉末への
吸着能が弱いために長期安定性が悪く、再凝集を起し易
くなかなか安定な懸濁液が得られない。However, according to this method, even if the lipophilic fine powder is dispersed by a surfactant, the long-term stability is poor due to the weak adsorption ability of the surfactant to the lipophilic fine powder, and reaggregation is likely to occur. It is difficult to obtain a stable suspension.

とすることを特徴とする。The present invention aims to solve the above-mentioned drawbacks by mixing lipophilic fine powder with heated and melted wax, mixing it with an emulsion containing a surfactant as a main ingredient, and suspending it. This suspension is filtered to create a suspension slurry, and by mixing and emulsifying this suspension slurry with an emulsion different from the above emulsion, a stable aqueous suspension of lipophilic fine powder is obtained.

にすぐれて安定した懸濁液が得られることになる。The product obtained as described above becomes a very stable suspension. At present, a lipophilic suspension can be obtained using a mixed solution of lipophilic fine powder and wax, and an emulsion of a surfactant. This is because the surface of lipophilic fine powder is usually composed of complex components, so it is thought that the adsorption ability of surfactants is weak, but when the components are coated with simple wax as in the present invention, The adsorption ability of the surfactant is very good and a stable suspension can be obtained.
