Abstract
The aim of the invention is to provide a resin composition used as a molding material and less resin compositions are sedimented on the moulding by attaching. A resin is supplied from the raw material feed port (1) of an extruder and plasticized in a plasticizing part (2). While air is exhausted from a first vent port (3) positioned on the downstream side of the plasticizing part (2) to the outside under a depressurized state, the resin plasticized in the plasticizing part (2) is fed to a mixing part (5), and a filler is fed from an auxiliary raw material feed port (4) positioned on the upstream side of the mixing part (5). While the plasticized resin is mixed with the filler in the mixing part (5) to form the resin composition, air is exhausted from a second vent port (6) positioned on the downstream side of the mixing part (5) to the outside under the depressurized state, the resin composition is discharged from a die (7) installed at the outlet of the extruder.

Implement preferred plan of the present invention
Embodiment of the present invention below are described.
1. extrusion molding operation
Employed extruding machine in the manufacture method of resin combination of the present invention has structure as illustrated in Figure 1.
Among Fig. 1, the 1st, material inlet, the main material that with the resinous principle is the center is from charging aperture 1 feed to extruding machine.The 2nd, plasticizing portion, above-mentioned main material here once plastified.The 4th, the auxiliary material charging aperture is generally supplied with auxiliary materials such as filler in extruding machine.The 5th, kneading portion carries out melt kneading through plasticized resin and the filler supplied with by auxiliary material charging aperture 4.The 7th, die head, the resin combination that obtains through melt kneading is by extruding from extruding machine here.Be provided with the 1st exhaust outlet 3 and the 2nd exhaust outlet 6 in the extruding machine, above-mentioned main material and resin combination in extruding machine carry out decompression exhaust with volatile ingredient, decomposed substance, high boiling substance etc.
The 1st exhaust outlet 3 is connected with decompressors such as vavuum pump, vapor steam blaster 8 with the 2nd exhaust outlet 6, to remove volatile ingredient, decomposed substance, high boiling substance etc. by plasticized resin and through the resin combination of melt kneading.
Therefore, the 1st exhaust outlet 3 is compared with plasticizing portion 2 and is preferably placed at the downstream; And compare with auxiliary material charging aperture 4 and to be preferably placed at the upstream.For the filler of being supplied with by auxiliary material charging aperture 4 is mediated, kneading portion 5 is positioned at the downstream of auxiliary material charging aperture 4.In order to remove volatile ingredient, decomposed substance, high boiling substance etc. by the resin combination of melt kneading, the 2nd exhaust outlet 6 is located at the downstream of kneading portion 5.
Upstream and downstream at auxiliary material charging aperture 4 among the present invention at least respectively are provided with an exhaust outlet, but also can therein any place or two places two or more exhaust outlets be set.
Resin combination of the present invention uses above-mentioned extruding machine by following operation manufacturing.
(i) supply with the operation of resin from the material inlet 1 of extruding machine;
After (ii) the resin by 2 pairs of supplies of plasticizing portion plastifies, the operation of carrying out exhaust down by the 1st exhaust outlet 3 decompressions that are positioned at plasticizing portion 2 downstreams;
(iii) being transported to kneading portion 5 through plasticizing portion 2 plasticized resin, supply with filler from the auxiliary material charging aperture 4 that is positioned at kneading portion 5 upstreams, plasticized resin and filler are mediated on one side at kneading portion 5 places, form resin combination, on one side under reduced pressure carry out exhaust from the 2nd exhaust outlet 6 that is positioned at kneading portion 5 downstreams operation; With
(iv) discharge the operation of gained resin combination from the die head 7 that is arranged on the extruding machine exit.
Resulting resin combination is extruded into the wire rod shape usually through die head 7, through cutting into graininess, uses as the feed particles of injection moulding machine etc.
Used extruding machine among the present invention can use normally used any type of extruding machine, preferred twin shaft multiple screw extruder (abbreviating Bitruder as).
The screw rod rotation of Bitruder both can be in the same way, also can be incorgruous, if the parallel dual-screw extruding machine, then screw rod both can be 3 screw threads, also can be 2 screw threads; If the incongruous double screw extruding machine then both can be a parallel axes, also can be inclined shaft.
Usually as the screw part that determines the screw rod pattern, the conveying of being made up of the forward screw thread constitutes with parts with parts and kneading portion with parts and plasticizing portion, and in the present invention, the plasticizing portion of extruding machine and the screw rod pattern of kneading portion should suitably design according to the character of resin and the kind of filler.If but the plasticizing capacity of plasticizing portion is low, then resin raw material can not fully plastify, and the decompression exhaust effect in the phase I will reduce certainly.
In order effectively to carry out decompression exhaust from the 1st exhaust outlet 3, between the auxiliary material charging aperture 4, extruding machine inside must be the state that can keep reducing pressure after plasticizing portion 2.For this reason, be full of sealing 9 in the extruding machine fully on the screw rod between the 1st exhaust outlet 3 and the auxiliary material charging aperture 4, must being provided with to make through plasticized resin.Any position of extruding machine inside is all sealed by plasticizing resin between plasticizing portion 2 and sealing 9, so can carry out decompression exhaust from the 1st exhaust outlet 3 well.
Constitute the screw rod shape of sealing 9, if the situation of Bitruder, except using reverse thread, can also preferably use seal washer, reverse kneading etc. to have boost capability rotating with respect to screw rod geometrically.Parts formations such as kneading disk can also have been made up simultaneously as required.
