[0116] Below, refer to Figure 1 to Figure 11 The first embodiment will be described.
[0117] figure 1 Fig. 1 schematically shows the configuration of the continuous high-shear processing device (kneading device) 1 according to the first embodiment. The high-shear processing device 1 includes a first extruder (treater) 2 , a second extruder 3 , and a third extruder (defoamer) 4 . The first extruder 2, the second extruder 3, and the third extruder 4 are connected in series with each other.
[0118] The first extruder 2 is a processor for kneading and melting two kinds of incompatible materials in advance, for example. Here, as two materials, a conductive filler and a thermoplastic elastomer are applied. These materials are supplied to the first extruder 2 in the state of, for example, pellets or powder.
[0119] Examples of the conductive filler used in the present invention include carbon-based conductive fillers such as carbon black, graphite, and CNT. In addition, exa...

[0200] Figure 12 A second embodiment is disclosed. The second embodiment is different from the first embodiment in terms of the rotating shaft 38 . The structure of the screw 21 other than that is basically the same as that of the first embodiment. Therefore, in the second embodiment, the same reference numerals are assigned to the same components as those in the first embodiment, and description thereof will be omitted.
[0201] Such as Figure 12 As shown, the refrigerant passage 71 is formed inside the rotating shaft 38 . The refrigerant passage 71 extends coaxially along the axis O1 of the rotary shaft 38 . One end of the refrigerant passage 71 is connected to an outlet pipe 73 at the joint portion 42 via a rotary joint 72 . The other end of the refrigerant passage 71 is closed in a liquid-tight manner by the front end of the rotating shaft 38 .
[0202] The refrigerant introduction pipe 74 is coaxially inserted into the refrigerant passage 71 . One end of the refr...

[0206] Figure 13 to Figure 18 A third embodiment is disclosed. The matters related to the screw body 37 of the third embodiment are different from those of the first embodiment. The structure of the screw 21 other than that is basically the same as that of the first embodiment. Therefore, in the third embodiment, the same reference numerals are assigned to the same components as those in the first embodiment, and description thereof will be omitted.
[0207] Such as Figure 13 to Figure 16 As shown, the screw body 37 has a plurality of conveying portions 81 for conveying the raw material, and a plurality of barrier portions 82 for restricting the flow of the raw material. That is, a plurality of conveyance units 81 are arranged at the proximal end of the screw body 37 corresponding to one end of the drum 20 , and a plurality of conveyance units 81 are arranged at the front end of the screw body 37 corresponding to the other end of the drum 20 . Furthermore, among these co...
