【発明の詳細な説明】 包装用緩衝材の再生方法、混合再生ペレットおよびこれを含む射出品 発明の分野 この発明は、発泡ポリエチレン（ＰＳ）、または発泡ＰＥ（ポリエチレン）＋ ＰＳ（ポリスチレン）の共重合体のような包装用緩衝材の再生方法に関するもの である。 従来の技術 環境公害問題が深刻になっており、環境に対する関心度がより一段と高まりつ つある時点で、単なる搬送のために使用される合成樹脂系列の包装用緩衝材、例 えば、発泡ポリスチレン（ＰＳ）、発泡ポリエチレン＋ポリスチレン（ＰＥ＋Ｐ Ｓ）共重合体などの廃棄問題が深刻に台頭されている。 これらの包装用緩衝材は、通常のプラスチック廃棄物に比べて体積が大きく、 ますますその使用量が増加される実情にある。従来、かような包装用緩衝材は焼 却または埋立てなどの方法によって廃棄されたが、かような廃棄方式はすべて環 境公害を誘発するものであるため、新たな廃棄方法が切に要望されている。 従来、プラスチック廃棄物を回収、再溶融して再度プラスチック製品として再 生する方法が公知となっている。 さらに、従来において、包装用緩衝材として使用される発泡ポリスチレンを再 活用企業で回収して新高品質ポリスチレン（ＨＩＰＳ）と混合して写真額縁およ び窓わくなどの素材として再生する方法が公知となっている。ところで、かよう な再生ポリスチレン樹脂は物性面で脆弱し、剥離現象が現われるなどの問題があ った。 最近にいたって、発泡ＰＥ＋ＰＳ共重合体が既存の発泡ポリスチレン緩衝材よ り衝撃吸収性、靭性、繰り返し荷重に対する耐久力などの物理的特性に優れ、包 装用緩衝材として使用する際、包装体積が減少されて物流費の節減効果が発生さ れるため、発泡ＰＥ＋ＰＳ共重合体の使用量が持続的に増加する趨勢にある。と ころで、いまのところ発泡ＰＥ＋ＰＳ共重合体を再生する方法は開発されていな い。 発泡ＰＥ＋ＰＳ共重合体に対する再生方法が開発されていない理由としては、 従来から通常ＰＥとＰＳ系列の樹脂は混合が不可能であると認識されているから であり、さらに、発泡ＰＥ＋ＰＳ共重合体に対しては、発泡ポリスチレンの場合 のように、一般的にフォーム態様の包装用緩衝材の再生品は、その物理的性質が 良好でないという認識のためであった。 発明の要約 本発明は上記種々の問題を解決するためになされたものであって、本発明の目 的は、包装用緩衝材の再生方法を提供し、また、発泡ＰＥ＋ＰＳ共重合体を含む 包装用緩衝材の再生方法を提供し、さらに、発泡ＰＥ＋ＰＳ共重合体を含む包装 用緩衝材の再生方法により再生された混合再生ペレットおよびこれを含む射出品 を提供することにある。 上記のような目的を達成するためになされたこの発明による包装用緩衝材の再 生方法は、廃発泡ＰＥ＋ＰＳ共重合体を発泡ＰＥ＋ＰＳペレットに再生するもの であり、前記再生工程は、前記廃発泡ＰＥ＋ＰＳ共重合体の粉砕工程と、前記粉 砕された発泡ＰＥ＋ＰＳを溶融する工程と、その溶融されたＰＥ＋ＰＳからイン ゴットを形成する工程と、そのインゴットを押出する工程と、前記押出物を切断 してペレットにする工程とからなり、前記廃発泡ＰＥ＋ＰＳ共重合体は、ペレッ トに変換される前に水けをなくすよう乾燥させ、前記押出工程中顔料が添加され 、前記射出品は、１６０−２００℃の条件で射出されることを特徴とする。 図面の簡単な説明 以下、本発明による一実施形態について添付図面に沿って詳述する。 図１は、本発明による包装用緩衝材のリサイクルフローである。 発明の好ましい実施形態の詳細な説明 この発明は、図１に示すように、製造者が搬送中、製品の破損を防止するため の目的で合成樹脂緩衝材を使用して製品を包装した後、ユーザーに製品を配達し た後には製品から合成樹脂緩衝材を分離して廃棄する。 この際、再活用企業が廃棄された合成樹脂緩衝材を回収した後、材質別分離工 程（１０）に応じて紙類、ビニル類、廃発泡ポリスチレン、廃発泡ＰＥ＋ＰＳ共 重合体などにそれぞれ分離する。 廃発泡ＰＥ＋ＰＳ共重合体は、再生工程（２０）に応じてそれぞれ粉砕工程（ ３０）、溶融工程（４０）、インゴット形成工程（５０）、押出工程（６０）経 てから切断して再生ＰＥ＋ＰＳペレット（７０）にする。 さらに、再生ＰＥ＋ＰＳペレット（７０）は、射出工程（８０）に投入させる ことによって、製品の機能性部品（９０）として射出されて製造者に供給する。 この際、前記再生工程（２０）前に分離された廃発泡ＰＥ＋ＰＳ共重合体は、 乾燥工程（１００）を経るようにして水けを取ってから、前記再生工程（２０） に投入される。 前記押出工程（６０）で再生ＰＥ＋ＰＳ樹脂を押出する際、必要に応じて顔料 （たとえば、チタンなり、カーボンまたはこれらの混合物）を投入して白色系列 から黒色系列にいたるまで多様な濃度で着色が可能となる。 前記射出工程（８０）時には、再生ＰＥ＋ＰＳ樹脂の燃焼を防止するために、 １６０−２００℃以下の条件で射出作業を施して変色を防止する。 この発明の再生方法により再生されたＰＥ＋ＰＳ樹脂を利用して機能性部品（ ９０）を生産する場合、その再生樹脂は下記表１に示すように、従来のＡＢＳ樹 脂または新ＨＩＰＳ樹脂の物性値に近い物性値を示している。 表１は、ＡＳＴＭ（米国規格）により測定された物性値である。 表１ ＡＳＴＭ（米国規格）により得られた物性値 上述のように、この発明による包装用緩衝材の再生方法、混合再生ペレットお よびこれを含む射出成形品は、廃発泡ＰＥ＋ＰＳ共重合体の再生ペレット１００ ％を使用して機能性部品として射出できるため、焼却または埋立てなどの廃棄を 抑制して環境公害を減少できることはもとより、新たな機能性部品の原料を提供 する効果がある。 The method of reproduction DETAILED DESCRIPTION OF THE INVENTION cushioning material, mixed recycled pellets and FIELD The present invention of an injection product invention containing this co polyethylene foam (PS), or foamed PE (polyethylene) + PS (polystyrene) The present invention relates to a method for recycling a cushioning material for packaging such as a polymer. 2. Description of the Related Art At the time when the environmental pollution problem is becoming more serious and the level of concern for the environment is further increasing, a synthetic resin-based packaging cushioning material used only for transportation, for example, expanded polystyrene (PS) The problem of disposal of foamed polyethylene + polystyrene (PE + PS) copolymer and the like has been seriously raised. These packaging cushions are larger in volume than ordinary plastic waste, and the amount of use is increasing. Conventionally, such cushioning materials for packaging have been disposed of by incineration or landfill.However, since all such disposal methods cause environmental pollution, a new disposal method is urgently required. I have. 2. Description of the Related Art Conventionally, a method of collecting, remelting, and regenerating a plastic product again as a plastic product has been known. Furthermore, a method of recovering foamed polystyrene used as a cushioning material for packaging by a recycling company, mixing it with new high-quality polystyrene (HIPS), and recycling it as a material such as a picture frame and window frame has been known. I have. By the way, such a recycled polystyrene resin is fragile in terms of physical properties, and has a problem that a peeling phenomenon appears. Recently, foamed PE + PS copolymers have better physical properties such as shock absorption, toughness, and durability against repeated loads than existing foamed polystyrene cushioning materials, and the packaging volume decreases when used as a cushioning material for packaging. As a result, the amount of the foamed PE + PS copolymer is continuously increasing. By the way, a method for regenerating a foamed PE + PS copolymer has not been developed so far. The reason why the regeneration method for the expanded PE + PS copolymer has not been developed is that it has been conventionally recognized that it is impossible to mix PE and PS series resins. In contrast, as in the case of expanded polystyrene, reclaimed packaging cushions, generally in foam form, were due to the perception that their physical properties were not good. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned various problems, and an object of the present invention is to provide a method for regenerating a cushioning material for packaging, and to provide a method for packaging containing foamed PE + PS copolymer. It is another object of the present invention to provide a method for regenerating a buffer material, and further provide a mixed regenerated pellet regenerated by a method for regenerating a packaging buffer material containing a foamed PE + PS copolymer and an injection product containing the same. A method of regenerating a cushioning material for packaging according to the present invention, which has been made to achieve the above object, regenerates a waste foamed PE + PS copolymer into foamed PE + PS pellets. Pulverizing the copolymer, melting the pulverized expanded PE + PS, forming an ingot from the molten PE + PS, extruding the ingot, cutting the extrudate into pellets The waste foamed PE + PS copolymer is dried so as not to drain before being converted into pellets, and the pigment is added during the extrusion process. It is characterized by being ejected by. BRIEF DESCRIPTION OF THE DRAWINGS Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a recycling flow of the cushioning material for packaging according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION As shown in FIG. 1, the present invention relates to a method in which a manufacturer packages a product using a synthetic resin cushioning material for the purpose of preventing the product from being damaged during transportation. After the product has been delivered to the user, the synthetic resin cushioning material is separated from the product and discarded. At this time, after the recycling company collects the discarded synthetic resin buffer, it is separated into papers, vinyls, waste foamed polystyrene, waste foamed PE + PS copolymer, etc. according to the material separation step (10). . The waste foamed PE + PS copolymer is subjected to a pulverizing step (30), a melting step (40), an ingot forming step (50), and an extruding step (60) according to the regenerating step (20), and then cut to produce regenerated PE + PS pellets ( 70). Further, the recycled PE + PS pellet (70) is injected into an injection step (80), thereby being injected as a functional component (90) of a product and supplied to a manufacturer. At this time, the waste foamed PE + PS copolymer separated before the regeneration step (20) is drained so as to pass through the drying step (100), and then is introduced into the regeneration step (20). When extruding the recycled PE + PS resin in the extrusion step (60), if necessary, a pigment (for example, titanium, carbon or a mixture thereof) is added, and coloring is performed at various concentrations from a white series to a black series. It becomes possible. In the injection step (80), in order to prevent burning of the recycled PE + PS resin, an injection operation is performed under a condition of 160-200 ° C. or less to prevent discoloration. When the functional component (90) is produced using the PE + PS resin regenerated by the regenerating method of the present invention, the regenerated resin has the physical property values of the conventional ABS resin or new HIPS resin as shown in Table 1 below. It shows close physical properties. Table 1 shows physical property values measured by ASTM (U.S. standard). Table 1 Physical property values obtained by ASTM (US standard) As described above, the method for regenerating the cushioning material for packaging, the mixed regenerated pellets and the injection molded article containing the same according to the present invention can be injected as a functional component using 100% of the regenerated pellets of waste foamed PE + PS copolymer. In addition to reducing the environmental pollution by suppressing the disposal such as incineration or landfill, there is an effect of providing a raw material for a new functional component.
