Description

재활용수지를 이용한 합성수지관 및 그 제조방법{a}Synthetic resin pipe using recycled resin and its manufacturing method {a}

본 발명은 내부에는 일자형의 관이 압출 또는 나선형으로 성형되는 1차 성형관의 외측으로 내부에 재활용수지를 공급하여 프로파일을 공급하면서 신재로 감싸서 요철형태로 공급하여 1차 성형관과 일체형의 합성수지관을 성형하여 강도를 크게 향상시킬 수 있도록 하는 재활용 수지를 이용한 합성수지관 및 그 제조방법에 관한 것이다.The present invention is a synthetic resin tube integral with the primary molded tube and the primary molded tube by supplying in a concave-convex shape while supplying a profile while supplying a recycled resin inside to the outside of the primary molded tube in which a straight tube is extruded or spirally molded inside. The present invention relates to a synthetic resin tube using a recycled resin and a method for manufacturing the same, which can greatly improve the strength by molding the mold.

종래 표면이 비교적 매끄러운 합성수지(HDPE) 신재를 이용한 합성수지관은 내경으로 일자형태의 내경관을 성형하고, 그 외측으로 돌출부와 홈부를 교대로 성형하는 요철형의 관을 성형하여 이중구조를 제공함으로써 강도를 제공하는 것이었다.Synthetic resin tube using a new HDPE material, which has a relatively smooth surface, has a double structure by forming a straight inner tube with an inner diameter, and forming a concave-convex tube that alternately forms protrusions and grooves outside thereof. Was to provide.

그러나 이러한 합성수지관은 돌출부분을 이루는 요철형태가 얇은 판을 이루는 형상으로 형성되어 있으므로 돌출부분이 얇게 형성되고, 그 내부는 비어있는 공간상태를 갖고 있게 되므로 외부의 충격에 의하여 돌출부분이 홈부에 비하여 강도에 취약하여 쉽게 파손되는 결점이 있다.However, the synthetic resin tube is formed in the shape of a thin plate of the concave-convex shape forming the protruding portion, so that the protruding portion is formed thinly, and the inside thereof has an empty space state, so that the protruding portion is formed by the external impact. It is vulnerable to strength and easily broken.

따라서 전체적으로 강도를 크게 향상시킬 수 없는 결점이 있으며, 폐비닐이나 폐합성수지를 이용하여 재활용하는 다양한 방법이 제공된다.Therefore, there is a drawback that can not greatly improve the strength as a whole, there is provided a variety of methods for recycling using waste vinyl or waste synthetic resin.

폐합성수지를 재활용하는 방법은 폐합성수지를 사각형으로 성형하고 그 외측으로 사각형의 신재로 감싸도록 한 후, 공급되는 과정에서 사각형의 신재 사이에 I형 또는 H형의 연결부재를 이용하여 접착시키는 것이다.The recycling method of the waste synthetic resin is to form the waste synthetic resin into a rectangular shape and wrap it with a new square material on the outside thereof, and then, using the I-type or H-type connecting member between the new square materials in the process of supply.

그러나 이러한 재활용 폐합성수지를 이용한 합성수지관은 내부가 채워져 있는 상태이므로 관의 강도에 비하여 중량이 매우 무거워서 운반 및 보관이 어려운 결점이 있었다.However, the synthetic resin tube using such recycled waste synthetic resin has a defect that is difficult to transport and store because the weight is very heavy compared to the strength of the tube because the interior is filled.
