【発明の詳細な説明】
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以下となると、通常の混合方法で
は、２次凝集が起り良好な分散が得られない。従って、
高シェアーか与えられる装置によって機械的分散させれ
ばよいが、機械的分散させるには例えばロールが好まし
く特に３本ロールが最もシェアーを与え、無機物が良く
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 50 μm, secondary agglomeration occurs using normal mixing methods. Good dispersion cannot be obtained. Therefore,
Mechanical dispersion may be carried out using a device that can provide a high shear, but for mechanical dispersion, for example, rolls are preferable, and in particular, three rolls provide the highest shear and can disperse inorganic substances well.
現在、一般に使用されているロールはチルドロールであ
るが、これで混練りする場合モース硬度が７．０以上の
無機物を混練りしようとすると、ロールが摩耗し、製品
に汚物が入り、特に、充填量が７０重重量風上になると
摩耗の傾向が著しくなる。すなわち、充填量が７０重重
量風下では高硬度ロールとチルドロールとの摩耗の差異
は余りないが、７０重重量風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か増加するに
従い、液状樹脂と無機充填剤との要分散体を得るにはロ
ールニップ間隙を小さくする必要があ来のチルトロール
では、ロール面の摩耗がすこぶる大きく、分散体へのロ
ールの材質の混入が避けられず、混練り物が灰色又は黒
色に着色するので、カラーリンクができず、さらに鉄分
による電気絶縁性を低下させる欠点があった。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 using these rolls, the rolls will wear out and dirt will enter the product. When the filling amount is 70 dw upwind, the tendency for wear becomes significant. That is, there is not much difference in wear between the high-hardness roll and the chilled roll when the filling amount is 70 gw, but when the filling amount is 70 gw, the difference becomes large. In addition, 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 the required dispersion of liquid resin and inorganic filler. It is very large, and the material of the roll cannot be avoided in the dispersion, and the kneaded material is colored gray or black, so color linking is not possible, and the electrical insulation properties due to the iron content are reduced.
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より、無機充填剤のモ
ース硬度が７．０以上でかつ充填量が７０重重量風上で
あってもロールの摩耗がなく、それ故に、製品に汚物が
混入しない接着剤、塗料及び注型剤に適した混練物を得
ることができる混練り方法を提供するものである。The present invention solves these drawbacks, and by using a high hardness roll made of sintered metal oxide when kneading liquid resin and inorganic filler, the Mohs hardness of the inorganic filler can be improved. 7.0 or more and there is no wear of the roll even if the filling amount is 70 weight upwind, and therefore it is possible to obtain a kneaded material suitable for adhesives, paints, and casting agents that does not mix dirt into the product. This provides a kneading method that can be used.
すなわち、本発明は、粘度１００．０００ ｃｐｓ以下
である液状樹脂とモース硬度７〜１０、粒子径５０μ以
下の無機物質を有機溶剤存在下又は非存在下で混練する
にあたり、金属酸化物から選ばれた少なくとも１種以上
の焼結体を少くともその表面に具えた高硬度ロールを用
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, a mixture of metal oxides 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 filling amount is 0μ or less and the filling amount is 70 to 90% by weight. If the filling amount is less than 70% by weight, there will be a difference from conventional kneading, and if it exceeds 90% by weight, the physical properties of the kneaded finished product will deteriorate, which is not preferred. It is also possible to improve dispersion by adding an aromatic, ether, or ketone solvent to the mixed material.
