本発明は、液状樹脂と高硬度無機物質とを混練
する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of kneading a liquid resin and a highly hard inorganic substance.
従来、液状樹脂に無機充填剤を混練して均一に
分散させる方法としてはいろいろ提案されている
が、一般に無機充填剤の粒径が50μ以下となる

分散させることが可能である。 Conventionally, various methods have been proposed for uniformly dispersing inorganic fillers by kneading them into liquid resin, but in general, when the particle size of the inorganic filler is less than 50μ, secondary agglomeration occurs using normal mixing methods. Good dispersion cannot be obtained. Therefore, mechanical dispersion can be carried out using a device that can provide high shear, but for mechanical dispersion, for example, rolls are preferable, and in particular, three rolls can provide the most shear and can disperse inorganic substances well. be.

ロールとチルドロールとの摩耗の差異は余りない
が、70重量％以上になるとその差は大きくなる。
また、充填剤の粒径が小さく充填量が増加するに
従い、液状樹脂と無機充填剤との良分散体を得る
にはロールニツプ間隙を小さくする必要がある
が、ニツプ間隙が５〜20μ程度になると、従来の

性を低下させる欠点があつた。 Currently, the rolls commonly used are chilled rolls, but if you try to knead inorganic materials with a Mohs hardness of 7.0 or higher, the rolls will wear out and dirt will enter the product. When the amount exceeds 70% by weight, the tendency for wear becomes significant. That is, when the filling amount is 70% by weight or less, there is not much difference in wear between the high-hardness roll and the chilled roll, but when the filling amount is 70% by weight or more, the difference becomes large.
Additionally, as the particle size of the filler decreases and the amount of filler increases, it is necessary to reduce the roll nip gap in order to obtain a good dispersion of liquid resin and inorganic filler. With conventional chilled rolls, the wear of the roll surface is extremely large, and the material of the roll is unavoidably mixed into the dispersion, and the kneaded material is colored gray or black, making it impossible to color. It had the drawback of lowering insulation properties.
本発明は、かかる欠点を解決したものであり、
液状樹脂と無機充填剤との混練りに当り、金属酸
化物を焼結した高硬度のロールを使用することに

できる混練り方法を提供するものである。 The present invention solves these drawbacks,
When kneading the liquid resin and inorganic filler, by using a high-hardness roll made of sintered metal oxide, it is possible to ensure that the Mohs hardness of the inorganic filler is 7.0 or more and the filling amount is 70% by weight or more. The purpose of the present invention is to provide a kneading method capable of obtaining a kneaded material suitable for adhesives, paints, and casting agents, which does not cause wear of the rolls even when the rolls are mixed, and therefore does not introduce dirt into the product.
すなわち、本発明は、粘度100000cps以下であ

高硬度ロールを用い、接着剤、塗料及び注型剤用
に適した材料を混練することを特徴とする。 That is, in the present invention, when kneading a liquid resin having a viscosity of 100,000 cps or less and an inorganic substance having a Mohs hardness of 7 to 10 and a particle size of 50 μ or less in the presence or absence of an organic solvent, at least one selected from metal oxides is used. The method is characterized in that materials suitable for adhesives, paints, and casting agents are kneaded using a high-hardness roll having at least one sintered body on its surface.

The material of the high-hardness roll used in the present invention is a roll made by sintering a solid solution consisting of one or more of metal oxides such as alumina, silica, magnesia, silicon nitride, and boron carbide, or the above-mentioned metal oxide.

~90% by weight. If the filling amount is less than 70% by weight,
No difference from conventional kneading is observed, and if it exceeds 90% by weight, the physical properties of the kneaded finished product will deteriorate, which is not preferable. In addition, aromatic, ether,
A ketone solvent can also be added to improve dispersion.
