Description
본 발명은 하수관이나 배수관으로 사용되는 스파이럴 파이프(Spiral pipe)에 관한 것으로, 특히, 폐플라스틱과 농업부산물 및 임업부산물 또는 플라이애쉬(fly ash)와 같은 충전재를 용융혼련(鎔融混練 ; Melt-blending)하여 사각 형태의 프로파일을 성형하고, 상기 프로파일을 수지 및 접착수지로 감싸서 접착시키되 프로파일 사이의 수지접착면이 H빔 형태가 되게 하여 외압, 충격 및 하중에 견고하도록 개량된 폐플라스틱을 이용한 스파이럴파이프 및 그 성형장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spiral pipe used as a sewage pipe or a drain pipe, and more particularly, melt-kneading a filler such as waste plastics, agricultural by-products, forestry by-products or fly ash. Spiral pipe using a waste plastic modified to form a rectangular profile, and wrap the profile with resin and adhesive resin to form an H-beam in the resin adhesive surface between the profiles. And a molding apparatus thereof.
일반적으로, 하수관이나 배수관으로 사용되는 관은 특허출원 제93-17640호로 제안된 "관 및 그 제조방법"에서 개시된 바와 같이, 회전하는 다수개의 회전 로울러에 원자재를 공급하면서 권취되도록 하며, 원자재 사이의 내, 외측면에 접착원료를 공급하면서 상기 로울러로 접착시키고, 냉각수 분사노즐을 통해 냉각수를 분사시키는 것에 의해 겔 상태의 원자재 접착원료를 냉각시켜 관을 형성한 것으로, 관의 내, 외부에 요철없는 I자형 접착 구조를 이루는 것이다.In general, a pipe used as a sewage pipe or a drain pipe is to be wound while supplying raw materials to a plurality of rotating rollers as disclosed in the "pipe and its manufacturing method" proposed in Patent Application No. 93-17640. The raw material is bonded to the roller while supplying the adhesive raw material to the inner and outer surfaces, and the raw material adhesive raw material in the gel state is cooled by spraying the cooling water through the cooling water spray nozzle to form a tube. It forms an I-shaped adhesive structure.
이러한 종래의 스파이럴 파이프 성형방법은 도 1 내지 도 3에 도시한 바와 같이, 압출기(3)에서 원료를 공급하면서 진공냉각조(20)를 통하여 내부에 사각형의 공간이 형성되도록 프로파일(23)을 성형하고, 프로파일(23)이 와인더(6)를 통과하는 과정에서 별도의 보조압출성형기(21)를 통하여 접착원료수지층(22)을 공급하게 되면 로울러(7)에 의하여 압착되면서 스파이럴 파이프(102)를 성형하는 것으로서, 도 1에 도시한 스파이럴 파이프 성형장치(101)에 의해 이루어진다.In the conventional spiral pipe forming method, as shown in FIGS. 1 to 3, the profile 23 is formed such that a rectangular space is formed through the vacuum cooling tank 20 while supplying raw materials from the extruder 3. In addition, when the profile 23 supplies the adhesive raw material resin layer 22 through a separate auxiliary extrusion machine 21 in the process of passing through the winder 6, the spiral pipe 102 is compressed by the roller 7. ) Is formed by the spiral pipe forming apparatus 101 shown in FIG.
그러나, 상기의 기존 방법에 의하면 사각의 프로파일(23)을 성형하기 위해 진공냉각조(20)를 거치게 되고, 이미 성형된 프로파일(23)의 접착을 위해 보조압출기(21)를 사용하여 상기 프로파일(23)의 일측면에 접착수지를 공급하는 것인 바, 이는 냉각된 프로파일(23)과 접착수지와의 온도편차로 인하여 접착이 제대로 이뤄지지 못할 뿐만 아니라, 프로파일(23)을 접착하는 접착수지층(22)이 전체적으로 I자 형태를 이루고, 또한 프로파일(23)이 중공형태의 구조를 가짐으로써 외부에서 가해지는 압력, 하중 및 충격에 그 접착부위가 매우 취약하여 쉽게 파단 및 분리될 수 있는 문제점이 있었다.However, according to the existing method, the vacuum cooling bath 20 is passed to form the rectangular profile 23, and the profile (using the sub-extruder 21 is used to bond the already formed profile 23). It is to supply the adhesive resin to one side of the bar 23, which is not properly adhered due to the temperature deviation between the cooled profile 23 and the adhesive resin, as well as the adhesive resin layer for adhering the profile 23 ( 22) has an I-shape as a whole, and also because the profile 23 has a hollow structure, the adhesive part is very vulnerable to pressure, load, and impact applied from the outside, so that it can be easily broken and separated. .
더욱이, 하수관 또는 배수관에서 사용되는 스파이럴 파이프(101)가 외압 작용으로 인하여 파단 및 분리될 경우에는 오염수가 토양에 스며들게 되어 토양 및지하수를 심하게 변질시킬 뿐만 아니라 지반 침하도 우려되는 심각한 문제점이 있었다.Moreover, when the spiral pipe 101 used in the sewage pipe or drainage pipe is broken and separated due to the external pressure action, contaminated water penetrates into the soil, thereby seriously deteriorating the soil and groundwater, and there is a serious problem of ground subsidence.

여기서, 수지(11)로 씌워진 프로파일(9)을 접착시키는 접착수지는 프로파일 (9)을 감싸되 그 형태가 H빔 형태가 되게 연속적으로 형성시키는 것이다.Here, the adhesive resin for adhering the profile 9 covered with the resin 11 surrounds the profile 9 and forms it continuously so that its shape becomes an H beam.
이러한 구성의 실시예를 첨부시킨 도면과 함께 상세히 설명하기로 한다.An embodiment of this configuration will be described in detail with the accompanying drawings.
(실시예)(Example)
각종 폐플라스틱 50∼100 중량부에 농업부산물 0∼50 중량부에 용융온도범위 180∼250℃로 압출기(3) 내에서 용융혼련한 후 사각 다이를 통해 압출시켜 복합체 구조의 도 5a와 같은 사각 프로파일(9)로 성형한다.50 to 100 parts by weight of various waste plastics and 0 to 50 parts by weight of agricultural by-products are melt-kneaded in the extruder 3 at a melt temperature range of 180 to 250 ° C. and extruded through a square die to form a square profile as shown in FIG. 5A. Molded by (9).
상기의 프로파일(9)은 성형 공급되는 과정에서 공기에 의해 냉각되며, 프로파일(9)의 양쪽에 설치된 보조압출기(4)에서 수지(11)를 공급하여 사각의 프로파일 (9)의 표면 전체에 도 5b와 같이 일정 두께의 수지(11)가 완전히 감싸지도록 한다.The profile 9 is cooled by air in the process of molding supply, and the resin 11 is supplied from the sub-extruders 4 installed on both sides of the profile 9 to cover the entire surface of the rectangular profile 9. As shown in 5b, the resin 11 having a predetermined thickness is completely wrapped.
이와 같이 수지(11)로 표면이 완전히 감싸진 프로파일(9)을 와인더(6)에 공급하여 원형의 구조물로 권취하는 과정에서 프로파일(9)을 서로 접착시키기 위하여 보조압출기(5)를 통해 접착용수지(12)를 공급하여 도 5c와 같이 씌운 후, 와인더 (6)에 귄취하게 되며, 로울러(7)의 회전 가압에 의해 압착되도록 하면 도 7과 같이 프로파일(9) 외측면에 완전 도포되면서 접착되어 접착수지층(12)을 이루게 된다.In this way, in the process of supplying the profile 9, the surface of which is completely covered with the resin 11, to the winder 6 and winding the circular structure, the adhesive 9 is adhered through the sub-extruder 5 to bond the profiles 9 together. After supplying the resin 12 and covering it as shown in FIG. 5C, the winder 6 is odorized and completely pressed onto the outer surface of the profile 9 as shown in FIG. 7 when it is compressed by the rotational pressure of the roller 7. While being bonded to form an adhesive resin layer (12).
이때, 상기 접착수지층(12)은 H빔 형태를 이루게 되어 외압, 충격 및 하중에 견고한 스파이럴 파이프(12)를 형성하게 되는 것이다.At this time, the adhesive resin layer 12 is to form a H-beam form a spiral pipe 12 that is robust to external pressure, impact and load.
본 공정에서 압출기(3)의 용융온도범위는 180∼250℃이므로 결정용융온도가 높아서 용융되지 않은 폐플라스틱은 공정의 특성상 상기 프로파일(9)의 중심부위에 용융되지 않은 상태로 뭉쳐있게 된다.Since the melting temperature range of the extruder 3 in this process is 180 to 250 ° C., the crystal melting temperature is high, and thus the waste plastic that is not melted is aggregated in an unmelted state on the center of the profile 9.
따라서, 프로파일(9)은 압출되면서 내층과 외층으로 나누어지고, 내층은 융점이 높은 폐플라스틱이 완전히 용융되지 않은 상태에서 농업부산물과 서로 혼련이 되어 있으므로 외압과 하중에 강하며, 외층은 융점이 상대적으로 낮은 폐플라스틱이 완전히 용융혼련되어 외부의 충격을 흡수할 수 있게 되고, 또한 압출기(3)의 다이를 거치면서 매끄러운 형태를 유지하기 때문에 접착수지와의 융착이 잘 이뤄질 수 있다.Therefore, the profile 9 is divided into the inner layer and the outer layer while being extruded, and the inner layer is strong in external pressure and load because the inner plastic is kneaded with the agricultural by-products in a state where the waste plastic with high melting point is not completely melted. As the low waste plastic is completely melt kneaded to absorb external impact, and also maintains a smooth shape through the die of the extruder 3, it can be easily fused with the adhesive resin.
또한, 보조압출기(4)(5)로 공급되는 접착수지에 의해 형성된 접착수지층(12)은 프로파일(9)의 외측에서 H빔 구조로 성형되므로 기존의 방법으로 성형되어진 스파이럴 파이프에 비해 현저히 높은 충격강도, 강성계수 및 원형 강성계수를 갖게 된다.(표 1참조)In addition, the adhesive resin layer 12 formed by the adhesive resin supplied to the sub-extruder (4) (5) is formed in an H-beam structure on the outside of the profile (9), which is significantly higher than the spiral pipe formed by the conventional method It has impact strength, stiffness coefficient and circular stiffness coefficient (see Table 1).
