本発明は、熱硬化性樹脂とガラス繊維を含む充填剤を撹

の製造法およびその製造装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a thermosetting resin molding material, in which a thermosetting resin and a filler containing glass fiber are put into a stirring mixer, kneaded and granulated, and an apparatus for producing the same.
従来より、熱硬化性樹脂と充填剤を撹拌混合機Ｉｒ−て
混練造粒し、乾燥することにより所定の流動波に調整し
て仕上げる方法が知られている。Conventionally, a method has been known in which a thermosetting resin and a filler are kneaded and granulated using a stirring mixer, and then dried to adjust the flow waves to a predetermined flow wave.
しかし、従来の撹拌□は、撹拌槽の底部に配置した回転

ちれる成形材料の粒度は不均一で、その射出成形時に可
塑化流動性のバラツキが大きくなり、定常的な熱圧安定
性、計量安定性、が得難い。However, conventional stirring is performed by a rotary blade placed at the bottom of the stirring tank, and it is difficult to obtain a uniform fIA# when glass fiber is contained as a filler. In other words, glass fibers are opened at the initial stage of kneading, so their volume increases, and the glass fibers and other materials that are being opened accumulate in parts where the flow inside the stirring tank is poor, causing a bridging phenomenon. This prevents uniform crosstalk. For this reason, the particle size of the molding material obtained is non-uniform, and the plasticization fluidity varies greatly during injection molding, making it difficult to obtain steady heat-pressure stability and measurement stability.
上記ブリッジ現象を解消するｋは０回転翼の段数を増や
すか、撹拌槽への原料の仕込量を減。To eliminate the bridging phenomenon mentioned above, either increase the number of rotary blades or reduce the amount of raw material charged into the stirring tank.

になる。It can be considered that However, even if the number of 0-rotation stages is increased and the bridging phenomenon is resolved by simply arranging them at the bottom, it is still not possible to uniformly open the glass fibers. Also, even if the amount of raw material □ is reduced, the same Ef
It is difficult to uniformly open the fibers, which increases the cost.
本発明の目的は、撹拌槽内での混線時、ガラス繊維のブ

とにある。The purpose of the present invention is to prevent the bridging phenomenon of glass fibers when wires are mixed in a stirring tank, dramatically improve the opening properties of glass fibers, and obtain a thermosetting resin molding material suitable for injection molding. It is in.

か発生する。しかし、上部にも撹拌手段を備えることに
より、′Ｉｊラス繊維は底部に押、し戻される形になり
、ブリッジ現象はなくなる。そして。In order to achieve the above object, the present invention has a method of reversing the stirring direction at the top and bottom of the stirring tank when kneading and granulating a filler containing a thermosetting resin and glass fiber in a stirring tank. Features. When a stirring means such as a rotary blade is provided only at the bottom of the stirring tank, a bridging phenomenon inevitably occurs at the top of the stirring tank. However, by providing stirring means at the top, the 'Ij lath fibers are pushed back to the bottom, eliminating the bridging phenomenon. and.
上部と下部で撹拌方向を逆にすることによって。By reversing the stirring direction at the top and bottom.
それぞれの方向に回転する原材料が互いに激しく衝突し
摩擦し、混練作用を助長し、混線時間を短かくできる。The raw materials rotating in different directions violently collide with each other and cause friction, which promotes the kneading action and shortens the crosstalk time.
また、撹拌槽内では原材料が常時むらなく混練されるの
て、嵩高くならず粒子の均一な成形材料が得られる。こ
れによって。In addition, since the raw materials are constantly and evenly kneaded in the stirring tank, a molding material with uniform particles without being bulky can be obtained. by this.
射出成形機の加熱加圧下における可塑化流動性が良好と

形性が向上する。The plasticization fluidity under the heat and pressure of the injection molding machine is improved, and steady reversal is possible with the screw rotation, improving moldability.
上部と下部で撹拌方向を逆にする為に１図面Ｉ【示すよ
うな撹拌混合機を用いることがてきる。In order to reverse the stirring direction at the top and bottom, a stirring mixer as shown in Figure 1 can be used.
撹拌槽１の上部と底部に水平回転する回転翼２゜３を備
える。回転翼２．３は反対方向化回転し。The top and bottom of the stirring tank 1 are equipped with rotary blades 2°3 that rotate horizontally. The rotor 2.3 rotates in the opposite direction.
上部と下部で撹拌芳向を逆にする作用をなす。The upper and lower parts act to reverse the stirring direction.
上部の材料投入口４から供給された原材料は。The raw materials supplied from the upper material input port 4 are as follows.
