본 발명은 폐폴리프로필렌수지로부터 종이의 분리 및 이의 재활용하는 방법에 관한 것으로, 보다 상세하게는 폴리프로필렌수지 포대의 제조시에 재단되는 폴리프로필렌수지 원단의 가장자리 부위의 폐폴리프로필렌수지에서 종이와 폐폴리프로필렌수지를 분리하여 폴리프로필렌수지를 재활용할 수 있도록 한 폐폴리프로필렌수지로부터 종이의 분리 및 이의 재활용하는 방법에 관한 것이다.The present invention relates to a method of separating and recycling paper from waste polypropylene resin, and more particularly, to waste paper and waste paper from waste polypropylene resin at the edge of a polypropylene resin fabric cut at the time of manufacture of the polypropylene resin bag. The present invention relates to a method of separating paper from recycled polypropylene resin and recycling the polypropylene resin to recycle the polypropylene resin.

일반적으로 폴리프로필렌수지는 석유 정제 시에 다량 발생하는 부산물인 프로필렌을 중합하여 제조하는 것으로, 상기 폴리프로필렌수지는 제조법과 성능면에서 획기적인 특유의 성능을 살려 카페트나 산업자재 분야에서 크게 특징을 발휘하고 있으며, 섬유 이외의 분야인 플라스틱 제품으로도 많은 수요가 있다.In general, polypropylene resin is produced by polymerizing propylene, which is a by-product generated in a large amount of petroleum refining, and the polypropylene resin shows great characteristics in the carpet and industrial materials fields by taking advantage of the innovative performance in terms of manufacturing method and performance. In addition, there is a great demand for plastic products that are fields other than fibers.

특히, 폴리프로필렌수지를 이용하여 포대를 제조할 경우 외부의 습기에 의한 내용물의 변질을 방지하고 신선도를 유지하며, 내구성이 우수하여 개나 닭과 같은 가축을 사육함에 있어, 이들의 먹이 즉, 사료를 넣어 보관 및 운반하고자 하는 용도로 사용되고 있고, 또한 벼나 쌀 등의 각종 곡물을 보관 및 운반하고자 하는 용도로 많이 사용되고 있는 실정이다.In particular, when the bag is manufactured using polypropylene resin, it prevents the deterioration of the contents caused by external moisture, maintains freshness, and has excellent durability in breeding livestock such as dogs and chickens. It is used for the purpose of storing and transporting, and is also used for the purpose of storing and transporting various grains such as rice or rice.

상기와 같은 사료용이나 곡물용으로 사용되고 있는 종래의 포대는 통상 종이재질로 이루어져 포대 가공이 용이하고, 사용후에도 재활용이 가능하다는 장점을 가져 많이 이용되었지만 종이재질의 취약점인 내구성 문제로 인해 물이나 습기에 약하고, 쉽게 훼손 및 파손되거나 또는 외부로부터 포대 내부로 습기가 침입되어 보관되어진 내용물을 변질시키거나 신선도를 저하시키는 문제점으로 인해 최근에는 폴리프로필렌재질의 포대를 많이 사용하고 있다.Conventional bags used for feed or grain as described above are usually made of a paper material is easy to process the bag, it has been used because of the advantage that can be recycled after use, but due to the durability problems that are weakness of the paper material due to water or moisture In recent years, polypropylene has been used in many cases due to a weak, easily damaged and damaged or moisture invading the inside of the bag to deteriorate the stored content or to reduce the freshness.

이러한 사료 또는 곡물을 보관 및 운반하기 위한 포대로 제조되는 폴리프로필렌수지 원단은 도1에 도시된 바와 같이 양쪽 가장자리 부위에 종이재질을 이용하여 열처리방식으로 융착되어 감겨져 있는데, 이는 상기 폴리프로필렌수지 원단이 감겨진 상태로 보관 또는 운반시에 원단 내부로 습기가 침입하는 것을 방지하기 위해 원단의 양쪽 가장자리 부위에 종이를 열융착하여 형성되게 하는 것이다.The polypropylene resin fabric manufactured as a bag for storing and transporting such feed or grain is fused and wound by heat treatment using a paper material at both edge portions as shown in FIG. 1, which is a polypropylene resin fabric. It is to be formed by heat-sealing the paper on both edges of the fabric to prevent moisture from entering the inside of the fabric during storage or transportation in a wound state.

상기 폴리프로필렌수지 원단을 이용하여 포대를 제작하기 위해 원단을 사용하는 경우 통상적으로 열처리된 종이와 결합되어 있는 가장자리 부위는 사용할 수 없어 잘려지는데, 이러한 가장자리 부위의 종이가 열융착된 폴리프로필렌수지는 두루말이형태로 다시 되감겨진 상태로 분리된다.When the fabric is used to fabricate the bag using the polypropylene resin fabric, the edge portion which is usually combined with the heat treated paper cannot be used, and the edge portion of the polypropylene resin heat-sealed polypropylene resin is rolled up. It is detached and rewound in form.

이러한 폴리프로필렌수지 원단에서 분리된 종이가 열융착되어 있는 가장자리부위는 물에 단순히 침수시켜도 열융착된 종이가 폴리프로필렌수지에 견고하게 결합되어 있기 때문에 재활용에 상당한 어려움이 있어, 상업적 경제성이 없어 버려지게 되는데, 상기 두루말이 형태로 되감겨진 가장자리 부위의 폴리프로필렌수지는 버리기 위해서는 일반 쓰레기로 취급되지 않아 재활용센터에서 수거하여 소각장에 운반한 후, 소각함으로 인해 별도의 인력과 비용이 소요되는 문제점이 있다.The edges where the paper separated from the polypropylene resin fabric is heat-sealed have a considerable difficulty in recycling since the heat-sealed paper is firmly bonded to the polypropylene resin even if it is simply immersed in water. However, the polypropylene resin of the edge portion of the rewinding wound form is not treated as general waste to be discarded and then collected at a recycling center and transported to an incinerator, which causes a problem of additional manpower and cost due to incineration.

이에 상기 폴리프로필렌수지 원단의 사용시 발생하는 종이가 열융착된 가장자리 부위의 폴리프로필렌수지에서 종이와 폴리프로필렌수지를 분리하여 각각 재활용하는 가공방법에 대한 필요성이 대두되고 있다.Accordingly, there is a need for a processing method for separating and recycling paper and polypropylene resins from polypropylene resins at the edges of the paper heat-sealed when the polypropylene resin fabric is used.

본 발명은 상기의 종래 문제점을 해결하기 위해 안출한 것으로, 종이가 열융착되어 결합된 폐폴리프로필렌수지를 일정한 크기로 절단한 후, 해리기에 의한 회전하는 물과의 마찰력에 의해 종이와 폐폴리프로필렌수지가 용이하게 분리하여 폴리프로필렌수지를 재활용할 수 있도록 하는데 목적이 있다.The present invention has been made in order to solve the above-mentioned conventional problems, and after cutting the waste polypropylene resin bonded to the paper by heat fusion to a certain size, the paper and the waste polypropylene by the frictional force of the rotating water by dissociation The purpose of the resin is to easily separate and recycle the polypropylene resin.

상기의 목적을 달성하기 위하여 폴리프로필렌수지 포대를 제조할 때, 재단되는 폴리프로필렌수지 원단의 가장자리 부위의 종이가 열융착된 폐폴리프로필렌수지에서 종이와 폐폴리프로필렌수지를 분리하는 방법에 있어서, 종이가 열융착된 폐폴리프로필렌수지를 횡으로 일정한 크기로 절단해서 해리기 내에 투입하여 물과의 20중량% : 80중량%의 배합비율로 해서 30∼60분 정도로 교반을 통하여 종리를 불림과 동시에 물과의 마찰에 의해 종이와 폴리프로필렌수지를 해리하여 종이는 침전되도록 하고, 폴리프로필렌수지는 부상되도록 하는 해리공정; 해리공정에 의해 부상된 폴리프로필렌수지를 채취해서 통상의 세척조에 투입하여 세척 및 탈수한 후, 이를 용융시켜서 칩형태로 압출하여 가공하는 압출공정;으로 제조하는 폐폴리프로필렌수지로부터 종이의 분리 및 이의 재활용하는 방법을 구현하고자 한 것이다.In order to achieve the above object, in manufacturing a polypropylene resin bag, in the method of separating paper and waste polypropylene resin from waste polypropylene resin heat-sealed the paper of the edge of the polypropylene resin fabric to be cut, paper The heat-sealed waste polypropylene resin is cut into a horizontal size and put into a dissociator to make 20% by weight of 80% by weight of the mixing ratio with water. A dissociation step of dissociating the paper and the polypropylene resin by friction with the paper so that the paper is precipitated and allowing the polypropylene resin to float; Separation of paper from the waste polypropylene resin produced by the extrusion process of collecting the polypropylene resin floated by the dissociation process, put it into a conventional washing tank, washing and dehydrating, melting and extruding it in the form of chips; We wanted to implement a recycling method.

이하, 도면을 참조하여 본 발명에 적용되는 폐폴리프로필렌수지에서의 종이를 분리하는 방법에 대하여 상세히 설명한다.Hereinafter, with reference to the drawings will be described in detail a method for separating the paper from the waste polypropylene resin applied to the present invention.

도1은 폴리프로필렌수지 원단에 종이가 열융착되어 감겨진 상태를 도시한 예시도이고, 도2는 본 발명에 적용되는 종이와 폐폴리프로필렌수지를 분리하는 공정도이다.1 is an exemplary view showing a state in which paper is heat-sealed and wound on a polypropylene resin fabric, and FIG. 2 is a process diagram for separating paper and waste polypropylene resin applied to the present invention.

폴리프로필렌수지를 이용하여 포대를 제조하기 위해서는 폴리프로필렌을 녹여 폴리프로필렌 원사를 추출하여 띠 형태의 폴리프로필렌실을 가공하고, 상기 폴리프로필렌실을 엮어서 망사형태의 폴리프로필렌원단으로 형성한 후, 상기 폴리프로필렌원단의 가장자리 부위에 종이재질을 이용하여 고주파 열처리로 열융착하여 폴리프로필렌원단에 종이가 견고하게 융착될 수 있도록 하고, 상기 폴리프로필렌원단은 제대기를 이용하여 포대를 완성하게 된다.In order to manufacture a bag using a polypropylene resin, the polypropylene is melted to extract a polypropylene yarn to process a polypropylene yarn in the form of a strip, and the polypropylene yarn is woven to form a mesh polypropylene fabric, and then the poly By using a paper material on the edge of the propylene fabric to heat-sealed by high-frequency heat treatment so that the paper is firmly fused to the polypropylene fabric, the polypropylene fabric is a bag using a umbilical cord.

이 때, 상기 폴리프로필렌수지 원단을 이용하여 포대를 제조하기 위해서는 폴리프로필렌수지 원단의 가장자리 부위에 열융착되어 있는 종이와 폐폴리프로필렌수지는 길게 잘려져 두루말이형태로 되감겨지게 되는데, 본 발명은 두루말이형태로 되감겨진 폐폴리프로필렌수지에서 종이와 폴리프로필렌을 분리한 후, 다시 재생원료로 가공하는 방법에 관한 것으로, 여기서는 이에 대하여 설명하기로 한다.In this case, in order to manufacture the bag using the polypropylene resin fabric, the paper and waste polypropylene resin, which are heat-sealed at the edges of the polypropylene resin fabric, are cut long and rewound in a rolled form. The present invention relates to a method of separating paper and polypropylene from waste polypropylene resin rewound and then processing it into recycled raw materials, which will be described herein.

[제1공정(절단공정)][1st process (cutting process)]

종이가 열융착되어 있는 두루말이형태의 폐폴리프로필렌수지는 절단기에 의해 횡으로 일정한 크기로 절단한다. 폐폴리프로필렌수지의 크기는 종이의 분리작업에 용이성을 필요하므로, 가능하면 소폭으로 절단하는 것이 가장 효율적이고, 특히, 폐폴리프로필렌수지로부터 종의 분리작업이 효율성을 얻도록 상기 절단된 형태의 폐폴리프로필렌수지를 24시간 정도의 물에 불리는 과정을 거치게 할 수도 있다.The rolled polypropylene resin, in which the paper is heat-sealed, is cut to a constant size laterally by a cutter. Since the size of the waste polypropylene resin is necessary for the separation of paper, it is most efficient to cut it as small as possible, especially the waste of the cut form so that the separation of species from the waste polypropylene resin can be made efficient. The polypropylene resin can be subjected to a process called water for about 24 hours.

[제2공정(분쇄공정)]Second Process (Pulverization Process)

상기 절단공정을 통해 절단된 형태의 폐폴리프로필렌수지와 물을 해리기 내로 투입하되, 물 80중량% : 폐폴리프로필렌수지 20중량%의 배합비율로 배합하고, 구동모터에 의해 회전하는 분쇄날을 작동하여 30∼60분 정도 교반하여 해리되게 하는데, 이 때 폐폴리프로필렌수지는 회전하는 분쇄날에 의해 교반을 통하여 종이를 불림과 동시에 회전하는 분쇄날에 의해 유도되는 물의 흐름방향으로 이동하면서 해리기 내에 형성된 기둥과 충돌하게 되고, 물과의 강한 마찰력에 의해 폐폴리프로필렌수지에 열융착된 종이가 서서히 떨어져 나가게 된다.The waste polypropylene resin and water of the form cut through the cutting process are introduced into a dissociation machine, and 80 wt% of water is mixed at a mixing ratio of 20 wt% of the waste polypropylene resin, and the grinding blade rotated by a driving motor. It is allowed to dissociate by stirring for 30 to 60 minutes. At this time, the waste polypropylene resin is dissociated while moving in the flow direction of water induced by the rotating grinding blade at the same time as the paper is soaked by the rotating grinding blade. It collides with the pillars formed therein, and the paper heat-sealed to the waste polypropylene resin gradually falls off due to the strong friction with water.

이 때, 물과 폐폴리프로필렌수지의 비율에 있어서, 물의 양이 적을 경우에는 해리기 자체에 과부하가 걸려 고장의 원인이 되기 때문에 물과 폐폴리프로필렌수지의 배합비율은 20중량% : 80중량%가 바람직하다.At this time, in the ratio of water and waste polypropylene resin, when the amount of water is small, the dissociator itself is overloaded and causes a breakdown, so the mixing ratio of water and waste polypropylene resin is 20% by weight: 80% by weight. Is preferred.

[제3공정(분리공정)][3rd process (separation process)]

상기 분쇄공정을 통해 종이와 폐폴리프로필렌수지가 분리되면, 밀도차에 의해 종이는 침전되어 해리기 저면에 형성된 배출구를 통해 외부로 분리하여 통상적인 종이의 제조방법으로 재활용되어지도록 하고, 폐폴리프로필렌수지는 물 위로 부상하게 됨으로써, 종이가 분리된 폐폴리프로필렌수지를 획득할 수 있게 된다.When the paper and waste polypropylene resin are separated through the crushing process, the paper is precipitated due to the density difference and separated to the outside through an outlet formed on the bottom surface of the dissociator so that the paper is recycled using a conventional paper manufacturing method. The resin floats on the water, thereby obtaining waste polypropylene resin from which paper has been separated.

종이는 물보다 밀도가 크고, 폴리프로필렌수지는 물보다 밀도가 작으므로 종이>물>폴리프로필렌수지의 순서로 밀도가 형성되어 해리기 내에서 종이는 침전되고, 폴리프로필렌수지는 수면으로 부상하게 된다.Since paper is denser than water and polypropylene resin is less dense than water, the density is formed in the order of paper> water> polypropylene resin, and the paper precipitates in the dissociation phase, and the polypropylene resin rises to the surface. .

[제4공정(용융공정)]4th process (melting process)

상기 분리공정을 통해 획득된 폐폴리프로필렌수지는 세척조에 투입하여 2∼3번 정도 세척한 후, 탈수과정을 거쳐 폐폴리프로필렌수지에 묻어있는 물기를 제거하고, 용융시킨다.The waste polypropylene resin obtained through the separation process is put into a washing tank and washed 2 to 3 times, followed by dehydration to remove water from the waste polypropylene resin and to melt it.

[제5공정(압출공정)][Step 5 (Extrusion Step)]

상기 용융공정을 통해 용융된 폴리프로필렌수지는 칩형태로 압출하여 가공한다.The polypropylene resin melted through the melting process is processed by extrusion into a chip form.

상기와 같이 본 발명은 폴리프로필렌수지 포대를 제조하는 과정에서 재단되는 폴리프로필렌수지 원단의 가장자리 부위에 형성된 종이가 열융착된 폐폴리프로필렌 수지를 해리기에 의한 회전시 물과의 마찰에 의해 열융착된 종이와 폐폴리프로필렌수지가 용이하게 분리한 후, 폴리프로필렌수지를 칩형태로 압출하여 재생할 수 있도록 한다.As described above, the present invention is heat-sealed by friction with water during rotation by dissociating the waste polypropylene resin heat-sealed paper formed on the edge of the polypropylene resin fabric to be cut in the process of manufacturing a polypropylene resin bag After the paper and waste polypropylene resin are easily separated, the polypropylene resin can be extruded into chips to be recycled.
