본 발명은 폐수지를 이용한 도로경계석 제조방법 및 그에 의해 제조된 도로경계석에 관한 것으로, 보다 상세하게는 폐수지의 재활용을 통해 자원절감 및 환경보호를 도모할 수 있을 뿐 아니라, 경계석에 야간식별체를 결합하기 위한 별도의 공정이 필요 없어 생산성 향상 및 비용 절감이 가능한 폐수지를 이용한 도로경계석 제조방법 및 이 제조방법에 의해 제조되는 동시에 경량화된 조립식 결합구조를 통해 설치작업이 용이한 도로경계석에 관한 것이다. The present invention relates to a method of manufacturing road boundary stones using waste resins and road boundary stones manufactured by the same, and more specifically, to reduce resources and environmental protection through recycling of waste resins, as well as combining nighttime identifiers with boundary stones. The present invention relates to a road boundary stone manufacturing method using waste resin, which does not require a separate process for improving productivity and to reduce costs, and a road boundary stone which is easy to install through a lightweight prefabricated coupling structure.

도로경계석은 도로의 인도나 화단 등의 끝단을 따라 설치되어 차도와의 경계를 형성하는 도로 시설물로서, 예전에는 주로 콘크리트를 소정 형태의 형틀에 부어 굳히는 방식으로 제조되는 것이 일반적이었고, 경우에 따라 화강암이나 대리석과 같은 석재를 가공하여 제조되기도 하였다. Road boundary stones are road facilities installed along the edges of roads and flower beds to form a boundary with the roadway. In the past, it was common to manufacture concrete by pouring concrete into a mold of a certain type. It was also manufactured by processing stones such as marble or marble.

이러한 종래의 도로경계석 중에서, 석재로 이루어진 도로경계석의 경우, 외관이 미려한 장점은 있으나 지나치게 무거워 설치 작업이 매우 불편하고, 그 재료비용 및 가공비용이 높아 범용적으로 사용되지 못하고 있으며, 콘크리트 도로경계석의 경우 상대적으로 제조비용이 저렴하여 보다 일반적으로 널리 사용되고 있으나, 이 역시 과도한 중량으로 인해 설치 작업이 불편한 점은 마찬가지이며, 그 제조 시 형틀에 부어진 콘크리트의 양생을 위해 많은 시간과 넓은 장소가 소요되어 생산성이 떨어지고 비용 면에서도 효율적이지 못한 문제점이 있었다. Of these conventional road boundary stones, road boundary stones made of stone have an advantage of having a beautiful appearance, but are too heavy to be very inconvenient to install, and have a high material cost and processing cost, and thus are not used universally. In this case, the manufacturing cost is relatively inexpensive, so it is widely used. However, this is the same as the installation work is inconvenient due to the excessive weight, and it takes a lot of time and a large place for curing the concrete poured in the mold during the manufacturing process. There was a problem of low productivity and inefficient in terms of cost.

더욱이, 이러한 석재 또는 콘크리트 재질의 도로경계석들은 취성을 갖는 재질적 특성으로 인해 차량의 충돌을 비롯한 외부 충격에 의해 쉽게 깨지거나 균열이 생기고, 내부에 흡수된 수분의 결빙으로 인해 갈라지기도 하며, 제설을 위해 도로에 뿌려지는 염화칼슘 등의 화학 물질에 의해 부식되는 등 내구성이 떨어지는 문제점이 있었다. Moreover, these stone or concrete road boundary stones are brittle due to brittle material properties, which are easily cracked or cracked by external impacts such as vehicle collisions, and sometimes cracked due to freezing of moisture absorbed inside. There was a problem that the durability is poor, such as being corroded by chemicals such as calcium chloride sprayed on the road.

또한, 야간의 교통 안전을 위해, 도로경계석에 야광체나 재귀성 반사체(이하, '야간식별체'로 통칭함)를 설치하여 야간에 운전자가 도로경계석의 존재와 위치를 용이하게 식별할 수 있도록 하는 경우가 점점 늘어가고 있는데, 종래에는 제조된 경계석에 야간식별체를 부가적으로 설치하기 위한 별도의 공정이 필요하여 생산성 및 비용 면에서 불리한 문제점이 있었다. 특히, 경계석의 표면에 접착제 등을 이용하여 야간식별체를 접합하는 경우, 고정력이 약할 뿐 아니라 경계석이 외부로 돌출되어 차량의 접촉 시에는 물론 사람 등의 접촉으로 인한 작은 힘에도 쉽게 야 간식별체가 분리되고, 이를 피하기 위해 경계석의 표면에 홈을 내서 야간식별체를 삽입하여 고정하는 경우, 작업에 많은 시간과 비용이 소요되는 문제점이 있었다.In addition, for night traffic safety, a luminous or retroreflector (hereinafter referred to as 'night identification') is installed in the road boundary so that the driver can easily identify the presence and location of the road boundary at night. Increasingly, in the related art, a separate process for additionally installing a nighttime identifier in the manufactured boundary stone requires a disadvantage in terms of productivity and cost. In particular, when the night identifier is bonded to the surface of the boundary stone using an adhesive or the like, the fixing force is weak and the boundary stone protrudes to the outside, so that the night identifier can be easily applied even when the vehicle is in contact with a small force due to human contact. To be separated, in order to avoid the grooves on the surface of the boundary stone to insert the nighttime identification, there was a problem that takes a lot of time and money in the work.

한편, 합성수지 제품의 사용이 늘어남에 따라 버려지는 폐수지의 처리가 점점 더 중요한 문제로 부각되어 있다. 이에 따라 다양한 방식으로 폐수지를 재활용하는 방안이 제시되고 있는데, 현실적으로는 폐수지의 회수 및 분류, 세척 등, 전처리에 소요되는 비용이 상당하기 때문에, 매우 많은 양의 폐수지가 제대로 재활용되지 못하고 버려지고 있다. 따라서, 보다 간단한 전처리 공정을 통해 폐수지를 재생하여 사용할 수 있는 현실적 방안이 요구되고 있다. On the other hand, as the use of synthetic resin products increases, the disposal of waste resins that are thrown away becomes an increasingly important problem. Accordingly, there are proposed ways to recycle the waste resin in various ways, and in reality, a large amount of waste resin is not properly recycled because it is expensive to collect, sort, and wash the waste resin. Therefore, there is a need for a realistic way to recycle and use waste resin through a simpler pretreatment process.

The top and bottom perspective views of the road boundary stone manufactured thereby are shown in FIGS. 4 and 5, respectively.

상기 재료혼합공정(P1)에서 투입되는 충진재는 경계석의 강도를 보강하고, 치수안정석성 확보 및 적정한 중량 증가를 위한 것으로, 탄산칼슘, 모래, 탄산칼슘과 PMMA(Polymethylmethacrylate)의 혼합물 중 어느 하나, 또는 그 조합물로 이루어질 수 있으며, 폐수지의 중량비 100에 대하여 충진재를 중량비 10 내지 30으로 혼합하는 것이 바람직하다. 충진재를 중량비 10 이하의 소량으로 혼합할 경우에는 충진재의 효과가 제대로 발휘되지 못하고, 중량비 30 이상으로 많은 양을 혼합할 경우에는 회분율이 높아지는 등 재료의 물성이 떨어지게 된다. Filler introduced in the material mixing step (P1) is to reinforce the strength of the boundary stone, secure dimensional stability and appropriate weight increase, any one of a mixture of calcium carbonate, sand, calcium carbonate and polymethylmethacrylate (PMMA), or It may be made of a combination thereof, it is preferable to mix the filler in a weight ratio of 10 to 30 with respect to the weight ratio 100 of the waste resin. When the filler is mixed in a small amount of 10 or less by weight ratio, the effect of the filler is not properly exhibited, and when a large amount is mixed by more than 30 by weight, the material properties of the material are inferior.

상기 첨가제는 열에 의한 분해나 변질을 방지하기 위한 스테이린산과 같은 열안정제와 자외선에 의한 광열화 작용에 의해 분해되는 것을 방지하기 위한 살리실산에테르와 같은 자외선흡수제를 포함한다. 이 첨가제는 주재료인 폐수지에 이미 포함되어 있는 경우가 대부분이므로, 전체 혼합물의 0.5 내지 1% 이내의 소량을 투입해도 충분한 효과를 얻을 수 있다.The additive includes a heat stabilizer such as stearic acid to prevent decomposition or alteration by heat and an ultraviolet absorber such as salicylic acid ether to prevent degradation by photodegradation by ultraviolet light. Since most of these additives are already included in the waste resin as the main material, a sufficient effect can be obtained even if a small amount of 0.5 to 1% of the total mixture is added.

한편, 도시하지는 않았으나, 상기 혼합공정 전에 폐수지의 선별 및 파쇄가 이루어지는 것이 바람직하다. 즉, 폐수지에 포함된 목재나 금속 등 이물질을 제거하여 선별된 폐수지를 파쇄기 등으로 균일한 크기로 파쇄하여 용융성 및 성형성을 높이는 것이 바람직하다.On the other hand, although not shown, it is preferable that the waste resin is sorted and crushed before the mixing process. That is, it is preferable to remove the foreign substances such as wood or metal contained in the waste resin to crush the selected waste resin to a uniform size with a crusher to increase the meltability and formability.

혼합된 폐수지원료는 상기 1차용융공정(P2)을 통해 용융되면서 혼합된 재료들이 균일하게 섞이도록 가공된다. 이에 사용되는 용융장치는 스크류를 회전시켜 수지를 가압이송시키면서 히터에 의한 열을 가해 용융시키는 통상적인 합성수지 용융장치로 이루어질 수 있으며, 바람직하게는 원료가 고르게 녹을 수 있도록 혼련 성능을 향상시키고 적은 발열량으로도 성형이 가능하도록 이방향 2축 스크류를 구비하고, 원료의 이송 방향을 따라 점진적으로 높은 발열 온도를 내도록 히터의 온도를 구역 별로 조절 가능한 구조의 것이 바람직하다. 예를 들면, 스크류를 소정 구간 별로 공급부, 압축부, 믹싱부 및 계량화부로 구분하여 서로 다른 나선 형태를 갖도록 하고, 상기 공급부에서는 원료의 수분 제거를 위해 대략 100℃ 내외의 온도로 가열하고, 상기 압축부에서는 150 내지 200℃, 상기 믹싱부와 계량부에서는 200 내지 250℃ 정도가 되도록 점진적으로 온도가 높아지게 하여 과도한 열공급으로 인해 원료가 탄화되는 것을 방지할 수 있도록 한다. The mixed wastewater support material is processed so that the mixed materials are uniformly mixed while melting through the primary melting process (P2). The melting apparatus used for this may be made of a conventional synthetic resin melting apparatus that melts by applying heat by a heater while rotating the screw to pressurize and transfer the resin. Preferably, the melter improves the kneading performance so that the raw material can be melted evenly and has a low calorific value. It is preferable to have a bi-directional biaxial screw to enable the molding, and to control the temperature of the heater for each zone so as to gradually generate a high heat generation temperature along the feed direction of the raw material. For example, the screw is divided into a supply part, a compression part, a mixing part, and a metering part for each predetermined section so as to have different spiral shapes, and the supply part is heated to a temperature of about 100 ° C. to remove moisture of the raw material, and the compression is performed. The temperature is gradually increased to 150 to 200 ℃ in the mixing section, and 200 to 250 ℃ in the mixing section and the metering section to prevent the raw material is carbonized due to excessive heat supply.

상기 안료혼합공정(P3)은 선택적인 것으로, 경계석에 요구되는 색상이 있을 경우, 해당 발색이 이루어지도록 적정량의 안료를 1차 용융된 원료에 혼합한다. 이 안료는 대략 300℃ 이상의 온도에 대한 내열성을 갖으며, Q.U.V 테스트 500시간에 탈색이 발생되지 않는 유기안료를 사용하되, 그 혼합비율은 수지 또는 수지와 충진재가 혼합된 원료 100 중량비에 대하여 10 내지 15 중량비 정도로 하는 것이 바람직하다. The pigment mixing process (P3) is optional, if there is a color required for the boundary stone, the appropriate amount of the pigment is mixed with the primary melted raw material to achieve the color development. This pigment has a heat resistance to a temperature of approximately 300 ℃ or more, using an organic pigment that does not cause decolorization in the QUV test 500 hours, the mixing ratio of 10 to 100 weight ratio of the resin or the raw material mixed with the resin and filler. It is preferable to set it as about 15 weight ratio.

안료가 혼합된 재료는 안료의 착색이 균일하게 이루어지도록 상기 2차용융공정(P4)을 거친다. 이 2차용융공정(P4)은 전술한 1차용융공정(P2)과 동일한 방식으로 이루어질 수 있으므로, 상세한 설명은 생략한다. The material in which the pigment is mixed is subjected to the secondary melting step (P4) to uniformly color the pigment. This secondary melting process (P4) can be made in the same manner as the above-described primary melting process (P2), a detailed description thereof will be omitted.

상기 1차용융공정(P2) 또는 2차용융공정(P4)을 통해 용융된 원료는 금형에 투입되어 도 4 및 도 5에 도시된 경계석(10) 형태로 프레스 성형되며, 상기한 바와 같이 프레스 성형이 이루어지기 전에 금형 내부에 야간식별체(20)를 가설치한다. 이 야간식별체 가설공정(P5) 및 프레스성형공정(P6)이 도 2에 보다 상세하게 도시되어 있다.The raw material melted through the primary melting process (P2) or the secondary melting process (P4) is put into a mold and press-molded in the form of the boundary stone 10 shown in FIGS. 4 and 5, and press forming as described above. Before this is done, the nighttime identification body 20 is temporarily installed in the mold. This night-time identification body temporary process P5 and the press molding process P6 are shown in more detail in FIG.

도 2를 참조하여 설명하면, 프레스 성형을 위한 금형은 경계석(10)의 바닥면을 형성하는 제1금형(120)과 이 제1금형(120)에 결합되어 경계석(10)의 상부 및 측면부를 형성하는 제2금형(110)으로 이루어지며, 이 중에서 제2금형(110)의 내벽면에 상기 야간식별체(20)를 접착제 또는 양면테이프(30) 등을 이용하여 가접합한다(도 2의 (a)).Referring to FIG. 2, the mold for press molding is coupled to the first mold 120 and the first mold 120 to form the bottom surface of the boundary stone 10, and the upper and side portions of the boundary stone 10 are formed. It consists of a second mold 110 to be formed, of which the temporary identifier 20 is temporarily bonded to the inner wall surface of the second mold 110 using an adhesive or a double-sided tape (30) (FIG. 2) (a)).

상기와 같이 야간식별체(20)가 가설된 금형(110, 120)의 내부에 용융된 폐수지를 투입하여 프레스성형하는데, 경우에 따라 액상으로 용융된 재료를 닫힌 금형 내부로 주입하는 방식으로 성형이 이루어질 수도 있으나, 이러한 방식의 경우 주입되는 용융물에 의해 가설된 야간식별체(20)가 정위치에서 이탈될 우려가 있기 때문에, 본 실시예에서는 폐수지를 상온에서 유동성을 갖는 고체 형태가 되도록 하고, 소정량의 폐수지 덩어리(10')를 제1금형(120)의 상부에 배치(도 2의 (b))한 다음, 제1금형(120)을 제1금형(120)과 합체되도록 상향 이동시키되, 폐수지 덩어리(10')가 제2금형(110)의 내측 상면부에 먼저 접촉되면서 압축 성형(도 2의 (c) 및 (d))되도록 하여 제2금형(110)의 내부 측면부에 가설된 야간식별체(20)가 위치를 벗어나지 않도록 한 것을 예시하였다. As described above, the molten waste resin is pressed into the molds 110 and 120 on which the night identification body 20 is hypothetically press-molded. In some cases, molding is performed by injecting the molten material into the closed mold. Although it may be made, in this case, since the night identifier 20 hypothesized by the melt injected may be released from the home position, in this embodiment, the waste resin is made into a solid form having fluidity at room temperature. After placing the quantitative waste resin mass 10 'on top of the first mold 120 (FIG. 2 (b)), the first mold 120 is moved upwardly to be combined with the first mold 120. , The waste resin mass 10 'is first contacted with the inner upper surface of the second mold 110 to be compression-molded ((c) and (d) of FIG. 2) to be installed on the inner side surface of the second mold 110. Illustrated that the night identification 20 is not out of position.

한편, 이와 같이 폐수지 용융물을 유동성 고체 상태로 하여 성형하는 경우, 금형에 투입하기 전에 도 3에 도시된 바와 같이 병렬로 근접 설치된 둘 이상의 롤러(50) 사이로 폐수지 덩어리(10')를 통과시키면서 가압하여 기포를 제거하고 재료 의 혼화도를 높이는 것이 바람직하다.On the other hand, in the case where the waste resin melt is formed into a fluid solid state, the waste resin mass 10 'is passed between two or more rollers 50 closely installed in parallel as shown in FIG. It is desirable to pressurize to remove bubbles and increase the miscibility of the material.

상기와 같이 소정 시간 동안 프레스 성형이 이루어진 다음, 도 2의 (e)에 도시된 바와 같이 탈형이 이루어지며, 이때, 제2금형(110) 내부에 가설되었던 야간식별체(20)가 성형된 경계석(10)의 측면부에 매입되어 일체화된다. 이와 같이 경계석(10)의 성형과 야간식별체(20)의 장착이 동시에 이루어지므로, 종래와 같이 경계석에 야간식별체를 장착하기 위한 별도의 공정이 필요 없게 되어, 야간식별체가 구비된 경계석의 제조에 있어 생산성이 높아지고, 생산비용도 절감할 수 있게 된다. 또한, 야간식별체(20)가 경계석에 매입 설치되므로, 차량이나 사람 등 주변 이동물의 접촉으로 인한 손상을 현저하게 줄일 수 있다. After press molding is performed for a predetermined time as described above, demoulding is performed as shown in FIG. 2 (e), and at this time, the boundary stone in which the nighttime identification body 20 that was installed inside the second mold 110 is molded. It is embedded in the side part of (10), and is integrated. As such, the formation of the boundary stone 10 and the mounting of the nighttime identifier 20 are performed at the same time, so that a separate process for mounting the nighttime identifier in the boundarystone is not required as in the prior art, thus preparing the boundarystone with nighttime identifier. In this way, productivity increases and production costs can be reduced. In addition, since the nighttime identification body 20 is embedded in the boundary seat, damage due to contact of surrounding moving objects such as a vehicle or a person can be significantly reduced.
