Description
본 발명은 표면개질된 산화 그래핀을 포함하여 내마모도가 향상된 노면 표지용 융착식 테이프에 관한 것이다. The present invention relates to a fusion-adhesive tape for road markings with improved wear resistance including surface-modified graphene oxide.
도시의 인구집중이 심화됨에 따라 도시에 통행하는 차량이 기하급수적으로 증가하고 있다. 이에 따라 도로의 복잡화가 심해지게 되며, 복잡한 도로에서 운전자에게 다양한 정보를 전달하기 위한 노면 표지의 중요성이 높아지고 있다. As urban population concentration intensifies, the number of vehicles passing through the city is increasing exponentially. Accordingly, the complexity of roads is increasing, and the importance of road signs to convey various information to drivers on complex roads is increasing.
노면표지는 차선 구분, 진행방향, 횡단보도를 표시할 뿐만 아니라 제한속도, 어린이 보호구역, 노인 보호구역, 각종 도로의 입출구 등을 표시하는 기능을 수행한다. Road signs not only indicate lane division, direction of travel, and crosswalks, but also perform the function of indicating speed limits, child protection zones, elderly protection zones, and entrances and exits of various roads.
이러한 노면 표지는 보수 시 차량 통행을 제한해야 하기 때문에 빠른 시공이 가능한 것이 바람직하다. 노면 표지는 시공하는 방법에 따라 크게 1종 내지 5종으로 나뉘게 되며, 그 중 4종 노면표지용 도료는 열융착을 통해 아스콘 등에 노면표지를 시공할 수 있다. Because these road signs must restrict vehicle traffic during repairs, it is desirable that they can be constructed quickly. Road markings are largely divided into 1 to 5 types depending on the construction method, and among them, 4 types of road marking paints can be applied to asphalt concrete, etc. through heat fusion.
이러한 4종 노면표지는 열융착을 이용하므로 시공 시간이 짧은 장점이 있으나, 온도차에 의한 균열 및 박리가 쉽게 발생할 수 있고 쉽게 마모가 되는 문제점을 안고 있다. These four types of road markings have the advantage of short construction time because they use heat fusion, but they have the problem that cracks and peeling can easily occur due to temperature differences and are easily worn.
이에, 시공이 빠른 4종 노면표지의 장점을 살리면서도 노면과의 부착력이 우수하고, 온도 변화에도 균열이 쉽게 발생하지 않으며, 내마모도가 우수한 4종 노면표지의 개발이 필요한 실정이다. Accordingly, there is a need to develop four types of road markings that take advantage of the advantages of fast construction, have excellent adhesion to the road surface, do not easily crack despite temperature changes, and have excellent abrasion resistance.
본 발명의 목적은 내마모도가 향상되며, 노면과의 부착력이 우수하고, 시공 편의성이 향상된 노면 표지용 융착식 테이프를 제공하는 것이다. The purpose of the present invention is to provide a fusion-adhesive tape for road markings with improved abrasion resistance, excellent adhesion to the road surface, and improved ease of construction.

The fusion adhesive tape for road marking according to the present invention includes a heat-sealable resin portion, surface-modified graphene oxide with an average particle diameter of 2 to 20 ㎛, filler, wax and glass beads with an average particle diameter of 10 to 25 ㎛.
