発明の名称 (英語) MULTI-SCREW KNEADER AND METHOD FOR PRODUCING NANO-COMPOSITE USING SAID MULTI-SCREW KNEADER, AND DISK-SHAPED SEGMENT USED FOR SAID KNEADER AND SAID METHOD NEW
発明の概要(英語) Provided are: a multi-screw kneader in which extension and flow actions which act before and after small holes in a disk-shaped segment having the small holes can be sufficiently exhibited; a method for producing a nano-composite using the multi-screw kneader; and a disk-shaped segment used for said kneader and said method. This multi-screw kneader is provided with a plurality of kneading screws and a disk-shaped segment in a barrel. The disk-shaped segment partitions the inside of the barrel at a downstream side from a kneading material feeding part, and is provided with: a plurality of shaft penetrating sections through which the rotation shaft of each kneading screw pass in a rotatable manner; and a plurality of small holes which are perforated around the shaft penetrating sections and serve as flow passages for the kneading material. This method for producing a nano-composite includes a step of feeding nanoparticles as a resin additive by using the multi-screw kneader. This disk-shaped segment is provided with the shaft penetrating sections and the plurality of small holes.
従来技術、競合技術の概要(英語) BACKGROUND ART
The multi-axis kneading machine, (1) homogenizing: heterogeneous structure of the polymer after the polymerization reaction is eliminated, a mixture of additives, dispersing, (2) plasticizing the polymer, the melt: polymer plasticized, melted, calendering is supplied to the line or the like, (3) dehydrated, devolatilization (desolvation, de-monomer): drying of the polymer, the monomer contained in the polymer after polymerization, devolatilization of solvent, (4) the chemical reaction: polymerization, solution polymerization, chemical reaction such as grafting, (5) blend, alloy: different polymers, a mixture of comparator chibi riser, dispersion, (6) fiber reinforcing material, a mixture of the micro inorganic filler: mixture of fiber-reinforced material, a mixture of inorganic filling material, a micro-sized aggregates of the dispersion of the particles, (7) fiber-reinforced material such as carbon nanotubes, inorganic filler and mixing the nanoparticles (dispersion in the resin uniformly nano-order level refers to the.Or less, the same.): A mixture of fiber-reinforced material, a mixture of inorganic filling material, such as nano-sized aggregates of the dispersion of the particles, kneading according to a difference in purpose, shape and screw arrangement, with respect to the embodiments and the like, has been made in the development of various (non-patent document 1 of Table 2 refer to page 3.).
Kneading is, the multi-axis kneading kneading one of the basic techniques of 1.Kneading is, an ellipse-shaped plate-like member, arranged consecutively in the axial direction.With the rotation of the screw kneading and kneading, the kneaded material, kneading and the inner wall of the barrel between the guided, and the resulting mixture (for example, see Patent Document 1.).
Is increased and the twist angle of the kneading, the distribution, the effects of dispersion is increased.On the other hand, the twist angle becomes small, distribution, and the dispersion effect is reduced, the transfer effect can be increased.In addition, spreads the disk thickness of the chip unit and a large shear stress dispersion effect is increased.On the other hand, the disk thickness is small and the distribution effect is enhanced effect of dispersion is reduced.In this way, by changing the thickness and twist angle of the disk by changing the distribution and dispersion ability is made possible.
However, as described above for the purpose of kneading in a wide range, in particular, among the above-mentioned kneading purpose of the (7) fiber-reinforced material such as carbon nanotubes, nano-mixture of the inorganic filler is, only the control limit of the kneading.
In this case, the kneading using a kneading machine is a multi-axis, is dominated by shear, shear dispersion of the nanoparticles has a higher extension than the flow is considered to be effective.In addition, the shear flow velocity gradient material and the flow is torn off, the flow is extended, stretched in the direction of the principal stress in the material flow.
Therefore, the nano-mixture meet the needs of the new, higher elongation flow is realized by, instead of kneading, the blister discs have been proposed (for example, see Non-Patent Document 1.).The blister discs is, has small holes, the small hole by passing the material to be kneaded, that exhibit the extension flow action of the present invention.
