합성수지 재생물과 그 재생처리방법{RECLAIMED SYNTHETIC RESIN AND METHOD FOR PROCESSING THE SAME}Synthetic Resin Recyclate and Its Recycling Method {RECLAIMED SYNTHETIC RESIN AND METHOD FOR PROCESSING THE SAME}

본 발명은 합성수지 재생물과 그 재생처리방법에 관한 것으로, 보다 상세하게는 폴리프로필렌(Polypropylene; PP)과 폴리에틸렌(Polyethylene) 등의 합성수지제품을 왕겨숯 분말을 주재로하는 첨가물을 혼합하여 재활용이 가능하도록 재생하기 위한 합성수지 재생물과 그 재생처리방법에 관한 것이다. The present invention relates to a synthetic resin regenerated product and a regeneration treatment method thereof, and more specifically, it is possible to recycle synthetic resin products such as polypropylene (PP) and polyethylene (polyethylene) by mixing additives mainly based on chaff charcoal powder The present invention relates to a synthetic resin regenerated product for regeneration and a regeneration processing method thereof.

잘 알려진 바와 같이, 현재는 다양한 종류의 합성수지가 개발되어 다양한 형태의 제품의 형성에 적용되고 있는 바, 그러한 합성수지에는 폴리프로필렌이라든지 폴리에틸렌이 포함된다.As is well known, various types of synthetic resins have been developed and applied to the formation of various types of products. Such synthetic resins include polypropylene and polyethylene.

통상적으로, 폴리에틸렌은 냉동식품과 사용하기 적합하기 때문에 포장지용 필름이나 병 또는 전기절연재료라든지 내식용 라이닝재료로서 널리 사용되고, 폴리프로필렌은 압출성형/블로우성형/압축성형/사출성형/진공성형이 가능하면서 섬유라든지 필름 및 투명한 폼으로 형성되어 포장지 등의 필름형태로 사용되고 폴리에틸렌보다 유연해지는 온도가 높은 특징을 갖는다.Generally, polyethylene is widely used as a packaging film, bottle or electrical insulation material, or as a lining material for corrosion resistance because it is suitable for use with frozen foods, and polypropylene can be extruded, blow molded, compression molded, injection molded, or vacuum molded. While it is formed of fibers or films and transparent foam, it is used in the form of a film such as a wrapping paper and has a higher temperature that becomes more flexible than polyethylene.

그러한 폴리프로필렌이라든지 폴리에틸렌에 의해 형성된 합성수지제품은 그 필요성이 종료되어 폐기하기 위해 매립하는 경우는 그 특성상 자연적인 분해에 상당한 시일이 걸리기 때문에 환경오염의 주요인으로 되는 바, 그 때문에 폴리프로필렌이라든지 폴리에틸렌 등의 합성수지는 대개 소각에 의해 폐기시키게 되지만, 그 합성수지의 소각시에는 인체라든지 대기환경에 유해한 성분이 방출되어 환경오염이 초래될 가능성이 높다.Such polypropylene or synthetic resin products made of polyethylene are a major cause of environmental pollution when their necessity ends and landfills are disposed of for disposal. Therefore, they are a major cause of environmental pollution. Synthetic resins are usually disposed of by incineration, but incineration of the synthetic resins is likely to cause environmental pollution due to the release of harmful substances to the human body and the atmosphere.

따라서, 그러한 폴리프로필렌이라든지 폴리에틸렌 등의 합성수지에 대해서는 통상적인 소각폐기하지 않고 일종의 자원으로서 재활용하기 위한 재생처리가 적극적으로 검토되어야할 필요성이 증대되는 상황이다.Therefore, there is an increasing need to actively review the recycling process for recycling as a kind of resources without incineration and waste of synthetic resins such as polypropylene and polyethylene.

하지만, 합성수지로서의 폴리프로필렌과 폴리에틸렌은 상이한 특성(예컨대 용융 온도라든지 성형온도 등)을 가질 뿐만 아니라 일단 특정한 형태로 성형이 이루어진 상태에서는 본래의 특성이 상실되는 경우가 일반적이기 때문에 재생처리시 수밀적이면서도 통기성을 갖는 형태로의 재생처리가 필요하게 된다.However, polypropylene and polyethylene as synthetic resins not only have different characteristics (such as melting temperature or molding temperature), but also inherently water-tight during the regeneration treatment because the original properties are generally lost once they are formed in a specific form. The regeneration process in the form of air permeability is needed.

즉, 합성수지는 특정한 형태로 성형이 이루어지면 본래의 특성(물성적 특성)에 변화가 생기기 때문에 그 합성수지를 재활용하기 위한 재생처리의 효과가 그다지 높지 않은 실정이다.That is, since the synthetic resin is molded in a specific form, the original properties (physical properties) change, so the effect of the regeneration treatment for recycling the synthetic resin is not so high.

따라서, 본 발명은 상기한 종래기술의 사정을 감안하여 이루어진 것으로, 상호 다른 특성의 폴리프로필렌과 폴리에틸렌 등의 합성수지를 세척 및 분쇄하여 용융시키고 그 용융된 합성수지에 왕겨숯분말을 주재로하는 첨가물을 혼합하여 칩 (Chip)형태로 압출성형하여 재활용을 위한 신소재를 얻도록 된 합성수지 재생물과 그 재생처리방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described prior art, and the synthetic resins such as polypropylene and polyethylene having different characteristics are washed, pulverized and melted, and the additives mainly containing chaff charcoal powder are mixed with the molten synthetic resin. It is an object of the present invention to provide a synthetic resin recycled and a regeneration treatment method to obtain a new material for recycling by extrusion molding in the form of a chip (Chip).

The addition of the vinegar improved the adhesion between the synthetic resin crushed product and the chaff charcoal powder, and This is to improve deodorization / antibacterial function as a fundamental characteristic.

또, 선택적으로 상기 합성수지분쇄물에 왕겨숯분말과 초액이 투입된 결과물에 대해 은나노분말이나 황토 및/또는 이산화티탄을 투입하면 바람직하게 되는 바, 상기 은나노분말을 투입하게 되면 은성분에 의한 살균/항균력이 강화되고, 황토를 투입하게 되면 살균/항균력의 향상과 원적외선/음이온의 방출효과가 기대되며, 이산화티탄을 투입하게 되면 환경유해물질의 분해효과가 기대된다.In addition, it is preferable to add silver nanopowder, ocher and / or titanium dioxide to the resultant into which the rice husk charcoal powder and the vinegar are added to the synthetic resin powder. When the silver nanopowder is added, sterilization / antibacterial activity by silver component This is enhanced, and the addition of ocher is expected to improve sterilization / antibacterial activity and release of far-infrared / anion, and the addition of titanium dioxide is expected to decompose environmentally harmful substances.

따라서, 상기 합성수지분쇄물에 대한 첨가물로서는 왕겨숯분말과 초액을 기본적으로 함유함과 더불어 은나노분말과 황토 및 이산화티탄을 선택적으로 포함하 게 된다.Therefore, as an additive to the synthetic resin powder, it contains rice chaff powder and vinegar basically and silver nano powder, ocher and titanium dioxide.

그에 더하여, 상기 첨가물에는 합성수지분쇄물과의 혼합시 기포의 발생을 제거하기 위한 가소제가 대략 3％∼15％정도로 투입된다.In addition, a plasticizer for removing air bubbles during mixing with the synthetic resin powder is added to the additive in an amount of about 3% to 15%.
