Abstract
Description
본 발명은 자원순환(탈플라스틱)으로 기후대응분야(탄소중립)에 해당하는 친환경 Biomass TPU에 UV-Stability를 향상시킨 탄산칼슘을 첨가한 차선분리대의 지주 또는 포스트에 관한 것이다.The present invention relates to a support or post for a lane separator made by adding calcium carbonate with improved UV-stability to eco-friendly Biomass TPU, which is in the field of climate response (carbon neutrality) through resource recycling (plastic removal).
일반적인 도로에는 양방향의 차량 통행을 위하여 중앙선을 표시하고 있으며, 중앙선을 표시한 도로에서는 운전자 등이 각별한 주의를 하지 않을 경우, 자주 중앙선을 침범하여 대형사고가 발생하는 폐단이 있기 때문에 중앙선 부위에 차선분리대를 설치하게 된다. 또, 횡단보도나 도로변에서 공사가 진행 중이거나 사고가 발생한 경우 주의를 요하는 장소의 주위를 둘러 또는 인도쪽에 차선 분리대를 설치한다.On general roads, a center line is marked to allow vehicle traffic in both directions. On roads with a marked center line, if drivers do not pay special attention, they often cross the center line and cause major accidents, so lane dividers are installed near the center line. will be installed. Additionally, if construction is in progress or an accident occurs at a crosswalk or roadside, install lane separators around the area requiring caution or on the sidewalk.
통상 차선분리대는 도로면의 상부로 수직 돌출되며 차량의 진행 방향 양측에 수평대설치관이 돌출 형성된 지주와, 지주의 하단에 형성되어 지주를 지면에 설치하기 위한 지주설치부로 된 탄성을 갖는 강질의고무재로 된 지주부 및 지주의 수평대 설치관에 결합되어 이웃하는 지주를 연결하여 양측 차선을 분리하는 탄성을 갖는 강질의 고무재를 포함한다.Normally, the lane separator is made of elastic steel with a support that protrudes vertically from the upper part of the road surface and has horizontal installation pipes protruding on both sides of the vehicle's direction of travel, and a support installation part formed at the bottom of the support for installing the support on the ground. It includes a support made of rubber and a strong rubber material with elasticity that is coupled to the horizontal bar installation pipe of the support and connects neighboring supports to separate the two lanes.
차선분리대와 관련하여 특허 제10-2331428호는 도 1에 도시한 것과 같이, 수직으로 입설된 지주(100')와, 지주(100') 사이에서 수평 연장되는 복수의 가이드바(220')로 이루어지는 차선분리대에서, 가이드바(220')의 제1평면(201')에 반짝이 가루인 시선유도부(210')를 도포하여 운전자나 보행자의 주의를 환기시키는 구조를 개시하고 있다.In relation to the lane separator, Patent No. 10-2331428, as shown in FIG. 1, consists of a vertically erected strut 100' and a plurality of guide bars 220' extending horizontally between the struts 100'. In a lane separation zone, a structure is disclosed that draws the attention of drivers or pedestrians by applying a gaze guide portion 210', which is glitter powder, to the first plane 201' of the guide bar 220'.
차선분리대에서 기둥 역할을 하는 지주, 즉 포스트에 대하여 특허 제10-2126738호는 금속 재질의 지주를 제안하고 있다. 특허 제10-2118831호는 우레탄등의 소재를 제안하고 있다.Patent No. 10-2126738 proposes a metal pole for the pole that acts as a pillar in the lane divider. Patent No. 10-2118831 proposes materials such as urethane.
그런데, 차선분리대는 견고하고 내구성이 우수해야 하지만, 차량이 부딪히는 경우 차량의 파손을 최대한 방지하여 운전자를 보호하고, 포스트에 부딪히는 보행자도 보호해야 하므로 철 재질을 사용하는 것은 바람직하지 않으며 고가인 단점이 있다. 한편, 유연하고 탄력성이 좋은 우레탄 폼 소재를 너무 많이 사용하면 차량의 파손은 경감되지만, 차선분리대의 손상 우려가 있고 차량이 차선분리대를 뚫고 진입할 우려도 있다.However, the lane separator must be sturdy and durable, but when a vehicle collides with it, it must prevent damage to the vehicle as much as possible to protect the driver and also protect pedestrians who hit the post. Therefore, it is not advisable to use steel material, and it has the disadvantage of being expensive. there is. On the other hand, if too much flexible and resilient urethane foam material is used, damage to the vehicle is reduced, but there is a risk of damage to the lane divider and the vehicle may enter through the lane divider.
또, 현재의 차선분리대는 친환경적인 면이 전혀 고려되지 않은 부재로서, 리사이클링과 소각이 어려운 단점이 있다.In addition, the current lane separator is a material that does not take eco-friendly aspects into consideration at all, and has the disadvantage of being difficult to recycle and incinerate.
본 발명은 내구성과 강도가 우수하며 탄력성이 좋고 자원순환(탈플라스틱)으로 기후대응분야(탄소중립)에 해당하는 친환경 Biomass TPU에 UV-Stability를 향상시킨 무단횡단방지 차선분리대를 제공하는 것을 목적으로 한다.The purpose of the present invention is to provide a jaywalking prevention lane separator with improved UV-stability in eco-friendly Biomass TPU, which has excellent durability and strength, good elasticity, and is suitable for climate response (carbon neutrality) through resource circulation (plastic removal). do.
상술한 목적을 달성하기 위하여 본 발명은 바이오매스 TPU재질의 차선분리대의 지주로서, TPU(열가소성폴리우레탄), 바이오 폴리올(bio-polyols) 및 탄산칼슘을 포함하는, 지주를 제공한다.In order to achieve the above-described object, the present invention provides a support for a lane separator made of biomass TPU material, which includes TPU (thermoplastic polyurethane), bio-polyols, and calcium carbonate.

이하, 본 발명의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described.
본 발명의 차선분리대의 포스트는 TPU(열가소성폴리우레탄), 바이오-폴리올(bio-polyols)및 탄산칼슘을 포함한다.The lane separator posts of the present invention include TPU (thermoplastic polyurethane), bio-polyols, and calcium carbonate.
열가소성 폴리우레탄(TPU)은 완전히 열가소성인 탄성체이며, 용융 공정도 가능하다. 압출 뿐만 아니라 사출, 블로우 및 압축 성형 장비로도 제작할 수 있다. 열가소성 폴리우레탄은 높은 회복력, 탁월한 압축 변형률과 더불어 충격, 마모, 찢김, 악천후 및 탄화수소에도 저항성이 있게 만들어 주는, 디소시아네이트와 하나 이상의 디올 사이에서 중첨가 반응이 발생할 경우 생성되는 고유한 범주의 플라스틱이다. TPU는 가소제를 사용하지 않고도 유연성을 제공하는 것은 물론 광범위한 경도 및 높은 탄성을 제공하는 장점이 있다. Thermoplastic polyurethane (TPU) is a fully thermoplastic elastomer and can also be melt processed. It can be produced not only by extrusion, but also by injection, blow, and compression molding equipment. Thermoplastic polyurethanes are a unique category of plastics created when a polyaddition reaction occurs between a disocyanate and one or more diols, providing high resilience, excellent compression set, and resistance to impact, abrasion, tearing, adverse weather conditions and hydrocarbons. am. TPU has the advantage of providing flexibility over a wide range of hardness and high elasticity without using plasticizers.
열가소성 폴리우레탄은 다른 플라스틱 재질과 차별화되는 일부 공통된 성능의 특징이 있는데, 높은 내마모성, 탁월한 저온 내성 및 내구성, 오일, 그리스 및 수많은 용제에 대한 회복력, 넓은 온도 범위에서 탁월한 유연성 및 강력한 내후성 및 높은 방사 에너지 저항성이다.Thermoplastic polyurethanes have some common performance characteristics that set them apart from other plastic materials: high wear resistance, excellent low-temperature resistance and durability, resilience to oils, greases and numerous solvents, excellent flexibility and strong weather resistance over a wide temperature range, and high radiant energy. It is resistant.
본 발명에서, TPU의 소재로는 Hexanedioic acid polymer with1,4-butanediol 및 1,1'-methylenebis[4-isocyanatobenzene]인 것이 바람직하다.In the present invention, the TPU material is preferably hexanedioic acid polymer with 1,4-butanediol and 1,1'-methylenebis[4-isocyanatobenzene].
이러한 성분의 그레이팅 덮개는 열 내구성이 좋아 고온의 여름이나 지하 시설에 장착되기에 유리하다.Grating covers made of these ingredients have good thermal durability, making them advantageous for installation in high-temperature summers or underground facilities.
본 발명에서 바이오 폴리올은 하이드록시기(-OH)를 갖는 폴리올 화합물을 이용하며, 우레탄 반응을 통해 제조된다. 최근까지 폴리우레탄 산업에서는 석유화학 제품에서 얻어지는 폴리올을 원료로 사용하였으나 환경에 대한 경각심과 재생산 가능한 바이오폴리올의 요구가 꾸준히 증가하고 있다.In the present invention, bio polyol uses a polyol compound having a hydroxy group (-OH) and is produced through a urethane reaction. Until recently, the polyurethane industry used polyol obtained from petrochemical products as a raw material, but environmental awareness and demand for reproducible biopolyol are steadily increasing.
바이오폴리올의 제조방법은 크게 생물학적인 합성방법과 화학적인 합성방법으로 대별되는데, 비용 면에서는 후자의 유기 합성법이 선호된다.Methods for producing biopolyols are largely divided into biological synthesis methods and chemical synthesis methods, but the latter organic synthesis method is preferred in terms of cost.
본 발명에서 바이오 폴리올로는 Poly(1,3-propylene succinate; PPSu)인 것이 바람직하다. PPSu는 비교적 신제품으로 친환경 등급이 높은데, 에틸렌(Poly(1,3-ethylene succinate))이나 부틸렌(Poly(1,3-buthylene succinate))을 사용하는 것보다 친환경분해도가 좋기 때문이다.In the present invention, the biopolyol is preferably Poly(1,3-propylene succinate; PPSu). PPSu is a relatively new product and has a high eco-friendly rating because it has a better eco-friendly decomposition rate than using ethylene (Poly(1,3-ethylene succinate)) or butylene (Poly(1,3-butylene succinate)).
PPSu는 Bio-alcohol propylene glycol과 bio-organic acid succinic acid의 중합에 의해 형성된 것이 바람직하다.PPSu is preferably formed by polymerization of bio-alcohol propylene glycol and bio-organic acid succinic acid.
탄산칼슘은 매우 흔하게 볼 수 있는 성분으로 각종 암석에 흔하게 들어 있고, 생명체에서도 볼 수 있다. 방해석이나 아라고나이트는 순수한 탄산칼슘으로 이루어졌고, 석회석, 백악, 대리석 등에도 탄산칼슘이 많다.Calcium carbonate is a very common ingredient and is commonly found in various rocks and can also be found in living things. Calcite and aragonite are made of pure calcium carbonate, and limestone, chalk, and marble also contain a lot of calcium carbonate.
탄산 칼슘은 생명체에서도 흔히 찾아볼 수 있는데, 계란 껍데기, 조개, 소라, 달팽이 등의 껍데기가 탄산 칼슘으로 되어 있으며 굴의 껍데기는 사람이 먹는 칼슘 보충제로서 사용된다. 탄산칼슘은 저렴하고 비교적 무게도 가벼워 도로 작업 시의 아스팔트에 충전재, 미세한 가루로 만들어 콘크리트의 충전재로 사용하고 있다. 제지 공정에서 종이나 페인트나 플라스틱류에도 충전재로 첨가된다.또 친환경적이며,칼슘을 보충하기 위한 의약품이나 식품첨가물로도 사용된다.Calcium carbonate can also be commonly found in living things. The shells of egg shells, clams, conches, and snails are made of calcium carbonate, and oyster shells are used as calcium supplements for human consumption. Calcium carbonate is inexpensive and relatively light, so it is used as a filler in asphalt during road work and as a filler in concrete when made into fine powder. It is added as a filler to paper, paint, and plastics during the papermaking process. It is also environmentally friendly, and is also used as a medicine or food additive to supplement calcium.
특히, 본 발명과 관련하여, 탄산칼슘은 자외선 강화 성능을 가지도록 제조되는 점에 특징이 있다. 이를 위하여 탄산칼슘 제작 시 아민계 광안정제(HALS)와 같은 자외선 안정제나 하이드록시벤조에이트와 같은 자외선 흡수제를 혼합 또는 첨가한다. HALS는 자외선으로부터의 보호 과정 중 자동 재생되어 최종 제품의 사용 수명시까지 폴리머를 보호하는 장점이 있다. 자외선 흡수제는 자외선 에너지를 흡수하고, 가역적인 화학적 재배열을 통해 자외선 에너지를 열로 변환하여 소실시키는 작용을 한다. 두 재료를 함께 사용하면 최적의 자외선 보호 기능을 얻을 수 있다.In particular, in relation to the present invention, calcium carbonate is characterized in that it is manufactured to have ultraviolet ray strengthening performance. For this purpose, when producing calcium carbonate, an ultraviolet stabilizer such as amine-based light stabilizer (HALS) or an ultraviolet absorber such as hydroxybenzoate are mixed or added. HALS has the advantage of automatically regenerating during the protection process from ultraviolet rays and protecting the polymer until the useful life of the final product. Ultraviolet absorbers absorb ultraviolet energy and convert it into heat through reversible chemical rearrangement to dissipate it. Using the two materials together provides optimal UV protection.
탄산 칼슘과 같은 비금속 광물 분말은, 가격이 저렴하며, 환경 친화적이고, 백색도가 우수하여 색상 매칭이 쉽고 플라스틱의 충전재로 사용되면 플라스틱 제품의 치수 안정성, 온도 저항성 및 강성을 향상시키는 효과가 있다. 또, 표면 처리된 탄산 칼슘은 분해 플라스틱의 점도를 높이고 재료의 유동성을 향상시키며 에너지 소비를 줄이는 효과가 있다.Non-metallic mineral powders such as calcium carbonate are inexpensive, environmentally friendly, and have excellent whiteness, making color matching easy and when used as a filler for plastics, they have the effect of improving the dimensional stability, temperature resistance, and rigidity of plastic products. In addition, surface-treated calcium carbonate has the effect of increasing the viscosity of decomposed plastic, improving the fluidity of the material, and reducing energy consumption.
