Description

【発明の詳細な説明】 押出ミキサ 本発明は、所定の温度を有する押出物を製造する方法と装置に関する。[Detailed description of the invention] extrusion mixer The present invention relates to a method and apparatus for producing extrudates with a predetermined temperature.

高分子材料の架橋または加硫を行うためには、加熱が通常必要である。ホースや ケーブルの被覆物や他の形材の押出を行い、架橋をするために押出形材を加熱す ることは公知の実行である。押出形材は、蒸気、融解塩混合物、高温ガスや加熱 流動床に通したり、輻射熱にさらすことによって加熱することができる。これら のシステムの欠点は、高分子材料は通常、熱の不良導体であるため、熱が押出形 材の内部まで到達し必要な架橋反応を起こすのに可成りの時間を要することであ る。Heating is usually required to effect crosslinking or vulcanization of polymeric materials. hose or Extrusion of cable jackets and other profiles and heating of extruded profiles for crosslinking. This is a known practice. Extruded profiles can be made using steam, molten salt mixtures, hot gases or heating Heating can be done by passing it through a fluidized bed or by exposing it to radiant heat. these The disadvantage of this system is that polymeric materials are usually poor conductors of heat, so the heat It takes a considerable amount of time to reach the inside of the material and cause the necessary crosslinking reaction. Ru.

生産速度及び／又は架橋プロセスに使われる装置の寸法の経済性における改良は 、もし熱が押出物の内部で発生できれば達成することができ、この結果を達成す る２個の公知のシステムがある。一方のシステムは、押出物を必要な形状に形成 した後、押出物の中でエネルギを散逸するマイクロ波を使用する。他方のシステ ムは、材料を最終形状に形成する前に機械的エネルギの散逸によって高分子材料 を加熱する、し】わゆる“シャーヘッド”を使用する。Improvements in the production rate and/or dimensional economy of the equipment used in the crosslinking process may , this result can be achieved if heat can be generated inside the extrudate. There are two known systems. One system forms the extrudate into the required shape. Microwaves are then used to dissipate energy within the extrudate. the other system The system transforms polymeric materials by dissipating mechanical energy before forming the material into its final shape. Heat it using a so-called "sher head".

マイクロ波加熱システムは、極性物質を含有しなければならない処理材料の性質 にエネルギの散逸が大いに依存するという欠点を有する。ケーブル等の金属部品 を含有する押出形材にこの型の熱を加える時にも問題が生じる。The nature of the processing material that the microwave heating system must contain polar substances It has the disadvantage that the energy dissipation is highly dependent on Metal parts such as cables Problems also arise when applying this type of heat to extruded profiles containing .

シャーヘッドは、ヘッドの金属部品に接触する材料の早期架橋を防止するために これらの部品を冷却しなければならないという欠点を有する。この冷却により、 急速で一様な架橋にとって望ましくない押出物内の温度差が生じる。典型的なシ ャーヘッドにおいて、高分子材料は互いに速度差を有して回転する表面の間の環 状スペース内で剪断される。熱発生プロセスの性質と金属面を比較的冷たく維持 する必要により、環状スペースの周辺部よりも中央部により高い温度が発生する ことになる。半径方向での材料の運動が殆ど又は全然無く、実質的な熱伝導を起 こすには時間が不充分である。従って、この温度差はシャーヘッドの出口にある ダイに、それ故、形成されている製品に伝達される。The shear head is designed to prevent premature bridging of materials that come into contact with the metal parts of the head. This has the disadvantage that these parts must be cooled. With this cooling, Temperature differences within the extrudate result, which are undesirable for rapid and uniform crosslinking. Typical In the camera head, the polymeric material forms a ring between surfaces that rotate with a speed difference from each other. is sheared within the space. The nature of heat-generating processes and keeping metal surfaces relatively cool Due to the need to It turns out. There is little or no radial material movement, causing substantial heat transfer. There is insufficient time for scrubbing. Therefore, this temperature difference is at the exit of the shear head is transmitted to the die and therefore to the product being formed.

単一のスクリュー押出機において処理される高分子材料の分散混合を改良するた めに行われる作業の結果、キャビティトランスファミキサとして知られる装置が 開発された。このようなミキサの例が英国特許第９３０３３９号と欧州特許第０ ．０４８，５９０号に記載されている。キャビ、ティトランスフアミキサは高分 子材料の流れを切断及び配合して、例えば異なる顔料や他の添加剤の濃度の層を 効果的に混合すると共に、異なる温度を有する層を配合して熱的に均質な押出物 を製造することを助ける。キャビティトランスファミキサの副作用は、行われる 切断及び剪断作用を介して処理されている材料内に熱を発生することである。一 般的に、これはキャビティトランスファミキサの望ましくない効果として考えら れている。To improve the dispersive mixing of polymeric materials processed in a single screw extruder. As a result of the work carried out for this purpose, a device known as a cavity transfer mixer is It has been developed. Examples of such mixers are UK Patent No. 930339 and European Patent No. 0. ．． No. 048,590. The cabinet and tea transfer mixer are high-quality. Cutting and blending child material streams to create layers with different concentrations of pigments or other additives, for example. Effectively mix and blend layers with different temperatures to create thermally homogeneous extrudates help manufacture. Cavity transfer mixer side effects are done It is the generation of heat within the material being processed through the action of cutting and shearing. one Generally, this is considered an undesirable effect of cavity transfer mixers. It is.

By providing a method and apparatus for producing an extrudate having a predetermined temperature, be.

There is also provided an apparatus for carrying out the above method, in which the method can be performed.

キャビティトランスファミキサは、押出機の供給スクリューと同じ速度で駆動さ れる内方部材又は回転子を備えることができ又は押出スクリューと異なる速度で 独立に駆動してもよい。ミキサの回転子は固定外方部材又は固定子内で回転して もよいし又はミキサの回転子を内部に装着した外方部材自体を回転自在としても よい。The cavity transfer mixer is driven at the same speed as the extruder feed screw. The extrusion screw may be provided with an inner member or rotor that is They may be driven independently. The mixer rotor rotates within a fixed outer member or stator. Alternatively, the outer member itself with the mixer rotor mounted inside may be freely rotatable. good.

本発明の実施例を添付の図面を参照していかに例示する。Embodiments of the invention will now be illustrated with reference to the accompanying drawings, in which: FIG.

第１図は、供給スクリューと同じ速度で駆動される内方部材を有するキャビティ ミキサを備える本発明の第１実施例を示す。Figure 1 shows a cavity with an inner member driven at the same speed as the feed screw. 1 shows a first embodiment of the invention comprising a mixer;

第２図はキャビティミキサが押出スクリューと別個に駆動される本発明の別の実 施例を示す。FIG. 2 shows another implementation of the invention in which the cavity mixer is driven separately from the extrusion screw. An example is shown.

第３図は第２図に示した汎用型の本発明の実施例を詳細に示す。FIG. 3 shows in detail the general-purpose embodiment of the invention shown in FIG.

The extrudate is inside the extrusion casing 11. is sent to the cavity transfer mixer by the extrusion screw IO rotating at Ru. Thus, the feed rate of the extrudate is a function of the rotational speed of the extrusion screw 10. On the other hand, the speed at which energy is applied to the material in the transfer mixer is is a function of the speed of
