본 발명은 종래 산업폐기물로 취급되어 그 활용이 용이하지 않던 폐합성수지와 폐고무를 활용하여 물리적 특성을 향상시키고 야광 특성을 갖는 경계물에 관한 것이다.The present invention relates to a boundary material having improved luminous properties and physical properties by utilizing waste synthetic resins and waste rubber, which are conventionally treated as industrial waste and are not easily utilized.
산업폐기물로 취급되던 폐고무와 폐합성수지는 현재에도 꾸준히 증가하고 있으며, 그 예로서 폐타이어는 95년 1,395 만개, 중량으로 15만 톤에 이르렀으며, 1999년에는 2,272만 개를 넘어섰으며, 폐합성수지의 경우에는 94년 201.8만 톤에 해마다 13.0%이상씩 증가하여 1999년에는 290.2만 톤을 기록하였다.Waste rubber and synthetic resins, which were treated as industrial wastes, are still increasing today. For example, the number of waste tires reached 13.95 million units in 1995 and 150,000 tons by weight, and in 1999 exceeded 2.272 million units. In 1994, the annual increase was 201.8 million tons, an increase of more than 13.0% per year, and recorded 290.2 million tons in 1999.
상기 폐타이어의 경우에는 소각, 매립 등에 의해 처리되어 왔으나, 소각시 SOx, Nox, HCl등 대기 환경 오염원들이 발생하고, 매립의 경우에는 수질오염과 매립지의 부족 등에 의해 그 활용이 현재에는 거의 불가능한 실정이다. 이외의 방법 으로 현재는 고속도로 아스팔트 포장에 이용되거나 보도 블록, 고무벽돌 등을 제조하는 등 건설자재로의 활용에 대해 많은 연구가 이루어지고 있다.The waste tires have been treated by incineration, landfilling, etc., but when incinerated, air pollutants such as SOx, Nox, HCl are generated, and in the case of landfilling, the utilization of the waste tires is almost impossible due to water pollution and lack of landfills. to be. Currently, many researches have been made on the use of construction materials such as highway pavement, sidewalk blocks, and rubber bricks.
상기 폐합성수지의 경우에는 6대 범용 폐합성수지인 PP(polypropylene), HDPE(high density polyethylene), LDPE(low density polyethylene), PVC(polyvinyl, choloride), PS(polystyrene), ABS(acrylonitrile butadiene styrene)가 가장 많이 폐기되고 있다.In the case of the waste synthetic resin, the six general purpose waste synthetic resins, PP (polypropylene), HDPE (high density polyethylene), LDPE (low density polyethylene), PVC (polyvinyl, choloride), PS (polystyrene), ABS (acrylonitrile butadiene styrene) Most are being scrapped.
그리고 폐합성수지의 경우에는 최근 열분해 등의 기술을 통해 재활용에 많은 노력을 기울이고 있으나, 폐합성수지 특성에 따른 처리 및 선별에 의한 비용 및 작업시간의 장기화 등의 문제가 여전히 남아 있어 폐합성수지의 증가에 따른 처리량을 맞추기가 어렵다는 문제가 있다.In the case of waste synthetic resins, many efforts have been made to recycle them through technologies such as pyrolysis. However, there are still problems such as cost and prolonged working time due to treatment and sorting according to the characteristics of waste synthetic resins. There is a problem that it is difficult to match the throughput.
본 발명자는 폐합성수지를 경계물의 재질로 활용함으로써 재활용효과를 높일 수 있음에 착안하였으며, 이에 관련 기술을 살펴본 결과 경계물의 일종인 차선분리대와 관련하여 대한민국등록특허 10-0472091호(공고일자 2005.03.14)'도로용 고탄력 중앙/차선 분리대'에서는 고무, 우레탄, 합성수지 등의 탄성재질로 성형하는 차선 분리대에 대해 개시하고 있으나, 폐고무, 폐합성수지가 아닌 미사용된 재질을 사용함으로써 본 발명에서 추구하고자 하는 목적과는 상이하며, 또한 폐고무, 폐합성수지를 처리하기 위한 해결점을 제시하기 어렵다는 문제가 있었다.The present inventors conceived that the recycling effect can be increased by using waste synthetic resin as the material of the boundary material. As a result of examining the related technology, the present inventors have found that the Republic of Korea Patent Registration No. 10-0472091 (Announcement Date 2005.03.14) 'High-elasticity center / lane separator for road' discloses a lane separator molded from elastic materials such as rubber, urethane, synthetic resin, etc., but is intended to pursue in the present invention by using unused materials other than waste rubber and waste synthetic resin. There was a problem that it was difficult to present a solution for treating waste rubber and waste synthetic resin, which was different from the purpose.
상기와 같은 문제를 해결하고자, 본 발명은 종래 폐합성수지와 폐타이어 등 산업폐기물로서 그 처리가 곤란한 물질을 활용하여 제조되는 경계물을 제공함으로써 경계물로서의 기능적인 측면은 물론 종래 산업폐기물로서 처리에 곤란을 겪던 폐타이어와 폐합성수지를 효율적으로 처리할 수 있는 폐합성수지와 폐고무를 이용한 경계물의 제공을 발명의 목적으로 한다.In order to solve the above problems, the present invention provides a boundary manufactured by using materials that are difficult to process as industrial wastes, such as conventional waste synthetic resins and waste tires, as well as functional aspects as a boundary, as well as conventional industrial wastes in the treatment. It is an object of the present invention to provide a boundary material using waste synthetic resin and waste rubber that can efficiently treat waste tires and waste synthetic resins, which have been difficult.
상기 목적을 달성하기 위해, 본 발명은 폐고무와 폐합성수지의 혼합재질로 제조되는 경계물에 관한 것으로, 상기 혼합재질은 폐고무(a1) 20 ~ 30 wt%와, 폴리프로필렌(polypropylene) 40 ~ 60 wt%, 고밀도폴리에틸렌(high density polyethylene) 40 ~ 60wt%의 혼합으로 조성된 폐합성수지(a2) 70 ~ 80 wt%를 140 ~ 170℃에서 40 ~ 50rpm의 교반 속도로 5 ~ 10분간 교반한 폐고무/폐합성수지 혼합물(A) 80 ~ 85 wt%와,In order to achieve the above object, the present invention relates to a boundary material made of a mixed material of waste rubber and waste synthetic resin, the mixed material is 20 to 30 wt% of waste rubber (a1), polypropylene (polypropylene) 40 ~ 70 to 80 wt% of the waste synthetic resin (a2) formed by mixing 60 wt% and 40 to 60 wt% of high density polyethylene was stirred for 5 to 10 minutes at a stirring speed of 40 to 50 rpm at 140 to 170 ° C. 80 to 85 wt% of the rubber / waste synthetic resin mixture (A),
폴리올레핀계 수지와 무수말레인산을 1: 0.3 내지 0.4로 혼합한 점착성 수지와 미사용 폴리프로필렌(virgin PP)을 동 중량비율로 혼합한 유기첨가제(B) 10 ~ 15 wt%와,10-15 wt% of an organic additive (B) in which a polyolefin-based resin and maleic anhydride are mixed at a weight ratio of 1: 0.3 to 0.4 and an unused polypropylene (virgin PP),
형광안료(C) 5 ~ 10 wt%를 200 ~ 230℃로 2 ~ 5분간 교반하여 조성된 폐고무와 폐합성수지의 혼합재질의 야광 경계물을 주요 기술적 구성으로 하는 것으로, 상기 경계물은 고정식/이동식 중앙분리대, 화단형 중앙분리대, 차선분리대, 경계블록, 보차도 경계블록, 단면부 경계블록을 포함한다.Fluorescent pigment (C) 5 to 10 wt% by stirring at 200 to 230 ℃ for 2 to 5 minutes made of a luminous boundary of the mixed material of waste rubber and waste synthetic resin as the main technical configuration, the boundary is fixed / It includes a movable median, flower bed median, lane divider, boundary block, sidewalk boundary block, and section boundary block.
이하, 상기의 기술적 구성에 대해 상세히 살펴보고자 한다.Hereinafter, the technical configuration will be described in detail.
상기 폐고무는 폐타이어의 철심, 섬유부분을 제거한 후 파쇄하여 분말로 가공한 것으로 단위체적중량이 0.6 ~ 0.8 g/㎤인 것으로, 영하 170 ~ 200℃ 상태에서 순간 분쇄하여 10 ~ 30mesh의 분말인 것을 사용한다.The waste rubber is processed into a powder by crushing after removing the iron core and fiber portion of the waste tire, the unit volume weight is 0.6 ~ 0.8 g / ㎠, the instant grinding at minus 170 ~ 200 ℃ state is a powder of 10 ~ 30 mesh Use it.
상기 폐고무는 폐합성수지에 대해 20 ~ 30 wt%로 사용되는 것으로, 상기 사용범위를 벗어나게 되는 경우에는 폐합성수지와의 적절한 혼합이 이루어지지 않아 야광 경계물의 물리적 성질이 나빠질 수 있으므로, 상기 폐고무는 폐합성수지에 대해 20 ~ 30 wt%로 사용하는 것이 바람직하다.The waste rubber is used at 20 to 30 wt% with respect to the waste synthetic resin. When the waste rubber is out of the use range, proper mixing with the waste synthetic resin is not performed, and thus the physical properties of the luminous boundary may be deteriorated. It is preferable to use 20 to 30 wt% with respect to the waste synthetic resin.
상기 폐합성수지는 폴리프로필렌(polypropylene) 40 ~ 60 wt%, 고밀도폴리에틸렌(high density polyethylene) 40 ~ 60wt%의 혼합으로 조성된 것을 사용하는 것으로, 폐합성수지인 폴리프로필렌(polypropylene)와 고밀도폴리에틸렌(high density polyethylene)의 혼합으로 사용할 때 높은 인장강도와 굴곡강도를 기대할 수 있다.The waste synthetic resin is composed of 40 to 60 wt% of polypropylene and 40 to 60 wt% of high density polyethylene. The waste synthetic resin is polypropylene and high density polyethylene. High tensile and flexural strengths can be expected when used as a mixture of polyethylene).
상기 폐고무와 폐합성수지의 혼합시에는 140 ~ 170℃의 범위에서 가열하게 되며, 상기 가열온도에 따라 야광 경계물의 인장 강도에 많은 영향을 미치게 되는 것으로, 상기 온도범위를 벗어날 경우에는 인장 강도가 떨어지므로 상기 온도범위에서 가열이 이루어지는 것이 바람직하다. 구체적으로 인장 강도를 언급하자면, 140℃에서 가열하게 되는 경우에는 제작된 시편에 의한 인장 강도가 0.83kgf/㎟로 측정되고, 170℃로 가열하게 되는 경우에는 인장 강도가 0.70kgf/㎟로 측정되어 가열온도에 따른 인장 강도의 변화 폭이 크다는 것을 알 수 있다.When mixing the waste rubber and the waste synthetic resin is heated in the range of 140 ~ 170 ℃, it will have a significant effect on the tensile strength of the noctilucent boundary according to the heating temperature, the tensile strength is lowered if it is out of the temperature range Since the heating is preferably in the above temperature range. Specifically, referring to the tensile strength, when the heating at 140 ℃ is measured by the tensile strength of the produced specimen is 0.83kgf / mm2, and when heated to 170 ℃ the tensile strength is measured to 0.70kgf / mm2 It can be seen that the variation of the tensile strength with the heating temperature is large.
상기 유기첨가제는 폴리올레핀계 수지와 무수말레인산을 1: 0.3 내지 0.4로 혼합한 점착성 수지와 미사용 폴리프로필렌(virgin PP)을 1:1 중량비율로 혼합한 것을 사용한다. 이와 같은 구성의 유기첨가제는 사용하기 전에 비해 인장강도, 굴곡강도 등의 물성 및 표면 향상 면에서 2배 이상의 향상을 가져오는 것으로, 10 wt% 미만인 경우에는 인장강도, 굴곡강도가 떨어지고, 15 wt%를 초과하는 경우에는 인장강도, 굴곡강도의 향상을 더 이상 기대할 수 없으므로, 상기 유기첨가제는 10 ~ 15 wt%의 범위로 사용하는 것이 바람직하다.The organic additive is a mixture of a polyolefin-based resin and maleic anhydride 1: 0.3 to 0.4 of a pressure-sensitive adhesive resin and an unused polypropylene (virgin PP) in a 1: 1 weight ratio. The organic additive of such a structure brings about two times improvement in the properties and surface improvement of tensile strength, flexural strength, etc. before use, and when less than 10 wt%, the tensile strength and flexural strength are inferior, and 15 wt% In the case of exceeding, since it is no longer expected to improve the tensile strength and the flexural strength, the organic additive is preferably used in the range of 10 to 15 wt%.
상기 형광안료는 변성 폴리아마이드 수지와 형광염료의 고용체(완전하게 균일한 상을 이룬 고체의 혼합물)를 사용하는 것으로, 5 ~ 10 wt%의 범위에서 사용되며, 5 wt% 미만인 경우에는 발광 효과가 떨어질 수 있고, 10 wt%를 초과하게 되는 경우에는 경계물의 내충격성, 신율 등의 물성에 영향을 줄 수 있으므로, 상기 형광안료는 5 ~ 10 wt%의 범위에서 사용되는 것이 바람직하다.The fluorescent pigment is to use a solid solution of a modified polyamide resin and a fluorescent dye (a mixture of completely uniform solid phase), it is used in the range of 5 to 10 wt%, when less than 5 wt% has a luminescent effect If it falls, if it exceeds 10 wt% may affect the physical properties such as impact resistance, elongation, etc. of the boundary, the fluorescent pigment is preferably used in the range of 5 to 10 wt%.
이상에서 살펴본 바와 같이, 본 발명에 따른 폐고무와 폐합성수지의 혼합재질의 야광 경계물은 내충격성, 신율, 인장강도 등의 물리적 성질이 뛰어나고, 폐합성수지와 폐 고무 등의 산업폐기물을 효율적으로 처리하여 자원의 재활용 측면 및 폐기물 처리에 따른 환경 개선효과를 가지며, 폐합성수지의 경우 별도의 선별과정이 없어도 폐 고무와의 혼합재질로서, 재활용할 수 있어 작업 비용이 절감 및 작업효율성이 높고, 야광 기능을 가짐으로써 운전자의 시야를 확보하여 도로상에서의 운전을 더욱 안전하게 할 수 있는 보조기능을 갖는다.As described above, the luminous boundary material of the mixed material of waste rubber and waste synthetic resin according to the present invention has excellent physical properties such as impact resistance, elongation, and tensile strength, and effectively treats industrial waste such as waste synthetic resin and waste rubber. It has the effect of recycling the resources and improving the environment according to the waste disposal, and waste synthetic resins can be recycled as a mixed material with waste rubber even without a separate screening process, which reduces work costs and improves the efficiency of work. By having the driver's vision to secure the driving on the road has a secondary function that can be more secure.
