Abstract

PROBLEM TO BE SOLVED: To provide a screw of a twin-screw extruder in which a dispersion capacity is increased in a feed screw part of the screw and which disperses and kneads an inorganic filler well. SOLUTION: In a screw of an twin-screw extruder for kneading an inorganic filler in which a kneading disk part 4 in which plate-shaped kneading disks are laid to overlap each other is formed in the intermediate part of the screw constituted from a feed screw, the engagement clearance between it and the counter screw is made 1.0-3.0 mm, the mixing part 6 of a reverse feed screw having projections projected from the bottom surfaces of screw troughs are formed in the intermediate part of the upstream feed screw of the kneading disk part 4, and a high shear disk part 7 in which wider plate shaped kneading disks are laid to overlap each other is formed immediately upstream from the kneading disk part 4. Accordingly, since after a dispersion capacity being increased in the feed screw part of the screw and an inorganic filler being dispersed well, melting is done, the dispersion and kneading of the filler are carried out well, and initial defects are eliminated.

Referring to FIG. 3, a barrel (not shown) has a material supply port 1 at its base, and two Screws 3 composed of feed screws 2 are rotatably fitted while meshing with each other. A kneading disk portion 4 composed of a disk 4a for forward feeding, a disk 4b for non-feeding, and a disk 4c for reverse feeding is incorporated into the middle portion of the screw 3 from the upstream. The resin material mixed with the inorganic filler to be melted is melted by a heating device provided on the outer peripheral surface of the barrel and by shear heat insulation by the rotation of the screw, and the inorganic filler is dispersed and discharged from the tip.

部圧力が上昇し、押出し不能となってしまう。However, aggregation or poor dispersion of inorganic fillers that are difficult to disperse, when kneaded in a state where the resin is not melted, the fillers are severely sheared, and secondary aggregation is further caused to cause lumps. This causes poor dispersion, causes clogging of the screen at the tip, increases the pressure at the head, and makes extrusion impossible.

切れないために起因する。This is because the feed screw 2 of the conventional screw 3 has a poor dispersing ability, and the filler which has been sent to the dispersing kneading disk section 4 without being dispersed is hardly secondary-agglomerated. However, this is because dispersion cannot be performed.

In the screw of the twin-screw extruder for kneading inorganic filler kneaded with a portion, the meshing clearance with the mating screw is set to 1.0 to 3.0 mm, and the feed screw intermediate portion on the upstream side of the kneading disk portion is radially shifted from the screw valley bottom. A mixing portion of a reverse feed screw having a plurality of protrusions protruding from the mixing disk portion is provided, and a high-shear disk portion in which a plurality of wide plate-shaped knee disks are stacked immediately upstream of the knee disk portion is provided. A screw of a characteristic twin-screw extruder for kneading inorganic filler was used.

うにした。BEST MODE FOR CARRYING OUT THE INVENTION A mixing portion having a plurality of projections projecting radially from the bottom of a screw valley is provided in the middle of a feed screw portion having a poor dispersing ability, and a filler sent in a state of aggregation or poor dispersion is provided. At the same time, the filler is made “wet” with the resin material so that the filler does not aggregate. Also, the clearance between the mating screw and the mating screw is set to 1.0 to 3.0 mm, which is larger than usual, so that the material is not strongly sheared at the feed screw portion. A high-shear disk portion composed of a disk having a width wider than that of the above-mentioned disk was provided, and the kneading and melting of the material were performed by applying insufficient shearing at the feed screw portion.

る。The screw 5 of the twin-screw extruder for kneading inorganic filler of the present invention has a meshing clearance with a mating screw of 1.0 to 3.0 mm, which is larger than usual, so as not to apply strong shearing to the material, and at the intermediate portion of the feed screw 2. In order to make up for the dispersing ability lacking in the feed screw 2, a mixing portion 6 of a reverse feed screw provided with a plurality of projections 6a projecting radially from the screw valley bottom is incorporated. In addition, a high-shear high-shear disk consisting of a progressive disk 7a and a non-transport disk 7b immediately upstream of the conventional kneading disk section 4 and composed of disks thicker than the respective disk widths constituting the kneading disk section 4. A disk unit 7 is provided.
