BACKGROUND ART < RTI ID = 0.0 >

본 발명은 원형 돌출부 형성을 위한 2액형 상온경화형 플라스틱 조성물 및 이를 이용한 차선 시공방법에 관한 것으로서, 보다 상세하게는, 야간 또는 우천시 시인성을 향상시키고, 운전자의 졸음 또는 부주의에 의한 교통사고를 미연에 방지할 수 있는 차선을 형성하기 위한 2액형 상온경화형 플라스틱 조성물 및 이를 이용한 차선 시공방법에 관한 것이다.The present invention relates to a two-pack type room temperature curing type plastic composition for forming a circular protrusion and a lane laying method using the same. More particularly, the present invention relates to a two- The present invention relates to a two-pack type room temperature curing type plastic composition for forming a lane which can be used for a lane construction.

일반적으로 포장된 도로의 표면에는 도로의 진행방향 유도나 차량의 간격유지를 위해 도로의 표면에 플라스틱 조성물을 도포하여 차선을 형성하는데, 이러한 차선은 제한 속도, 진행방향 및 목적지의 정보 등을 표시하여 운전자의 편의성 및 안전을 도모한다.Generally, on the surface of a packed road, a plastic composition is applied to the surface of the road to form a lane to guide the direction of the road or maintain the clearance of the vehicle. These lanes mark the speed limit, And the convenience and safety of the driver are promoted.

전술한 목적으로 도포되는 플라스틱 조성물은 유성 플라스틱 조성물, 수성 플라스틱 조성물, 융착식 플라스틱 조성물로 구별되는데, 전술한 유성 플라스틱 조성물은 융착식 플라스틱 조성물에 비해 시공되는 자재의 두께가 얇아 마모층이 적거나 건조의 시간이 길어 차량 통행이 빈번한 도로일 경우 시공작업의 효율성이 저하되는 문제점이 있었다.The plastic composition to be applied for the above-mentioned purpose is distinguished from an oil-based plastic composition, a water-based plastic composition and a fusion-type plastic composition. The oil-based plastic composition described above is thinner than the fusion- The efficiency of the construction work is deteriorated in the case where the road traffic is frequent.

또한, 전술한 수성 플라스틱 조성물은 수성에멀젼 수지에 물이나 안료 등을 혼합하여 액상으로 제조되며, 수성 제품이라는 점에서 주위 시공 환경(온도나 습도)에 영향을 받고, 건조 시간이 느리기 때문에 시공상 제약이 많은 문제점이 있었다.In addition, the above-mentioned water-based plastic composition is produced by mixing water-based emulsion resin with water or pigment and is in the form of a liquid. Since it is an aqueous product, it is affected by the ambient environment (temperature and humidity) There were many problems.

또한, 전술한 일반 융착식 플라스틱 조성물은 열가소성 수지에 안료나 글라스 비드 등을 혼합한 것으로서, 분말 형태로 제조되어 현장에서 시공 시 1차 용해조에서 용해시킨 후 2차 시공기에서 뿌려주면서 시공하는 방식으로 작업이 수행되며, 상기 2차 시공기는 주로 인력이나 소형 원동기를 이용하였다. 이 방식은 도심지와 혼잡한 도로의 통행 제한을 최소화하면서 시공할 수 있는 방법으로 폭넓게 사용되고 있는데, 두께가 매우 얇고 미끄러워 도로면보다 오히려 마찰계수가 감소하는 문제점이 있어 자동차의 미끄러짐을 유발하고 보행자의 안전한 보행을 저해하며, 시공 후 크랙이 쉽게 발생하는 문제점이 있었다.In addition, the above-mentioned general fusion-type plastic composition is a mixture of a thermoplastic resin and a pigment or glass bead, and is manufactured in powder form, dissolves in a primary melting tank when it is applied in the field, and is sprayed from a second- Work is performed, and the secondary construction machine mainly uses a manpower or a small prime mover. This method is widely used as a method of construction while minimizing the traffic restriction of urban areas and congested roads. It has a problem that the thickness is very thin and slippery and the coefficient of friction is rather reduced rather than the road surface. This causes slippage of the vehicle, And it has a problem that a crack easily occurs after construction.

또한, 전술한 플라스틱 조성물에 의해 형성된 차선은 야간에 반사효율이 좋지 못해 시야확보가 어렵고, 우천시 시인성이 좋지 않아 운전자들로 하여금 교통사고를 미연에 방지하는 효과가 미미하였다.In addition, the lane formed by the above-described plastic composition has a poor reflection efficiency at night, making it difficult to secure visibility, and poor visibility in the case of rainy weather, thereby preventing drivers from having traffic accidents in advance.

이에 상술한 문제점들을 개선하기 위한 플라스틱 조성물에 대한 개발이 요구되고 있다.Accordingly, development of a plastic composition for improving the above-mentioned problems is required.

일 실시예에 있어서, 플라스틱 조성물은 주도료와 경화제를 혼합 시 요변성 부여제를 추가로 혼합할 수 있다. 요변성 부여제는 플라스틱 조성물에 요변성을 주어 수직에 가까운 면에 도장했을 때 흐르는 것을 방지하는 기능을 한다. 즉, 요변성 부여제는 원형 돌출부를 갖는 차선을 형성할 때, 돌출부의 형태를 잡아 주고, 견고하게 형성되도록 한다. 요변성 부여제는 클레이(clay)를 사용하는 것이 바람직하다. 클레이는 가느다란 함수 규산염 광물의 집합체로서, 적당량의 물을 섞어 반죽하면 가소성이 생기고, 건조시키면 강성을 나타내며, 높은 온도에서 구우면 소결하는 물질을 말한다. 구체적으로, 요변성 부여제는 해포석, 흄드 실리카 및 벤토나이트로 이루어진 그룹에서 선택된 적어도 어느 하나의 분말을 사용할 수 있으나, 가장 좋은 효과를 얻기 위해서는 흄드 실리카와 벤토나이트가 1:1의 중량비로 혼합된 것을 사용하는 것이 바람직하다. 요변성 부여제는 주도료 및 경화제가 혼합된 전체 100 중량부에 대해서 1~2 중량부 혼합되는 것이 바람직하다. 요변성 부여제가 1 중량부 미만이면, 흐름성을 충분히 제어할 수 없어 원하는 형태 및 크기의 돌출부보다 지름은 크고 높이는 낮게 형성될 수 있고, 2 중량부를 초과하면, 흐름성이 너무 사라져서 원하는 형태 및 크기의 돌출부보다 지름은 작게 높이는 높게 형성될 수 있다.In one embodiment, the plastic composition may further comprise a thixotropic agent when mixing the primary coating and the curing agent. The thixotropic agent functions to prevent the plastic composition from flowing when it is applied to a surface near the vertical by imparting thixotropy to the plastic composition. That is, when forming the lane having the circular protrusion, the thixotropic agent forms the protrusion and forms it firmly. The thixotropic agent is preferably a clay. Clay is an aggregate of fine hydrated silicate minerals. It refers to a material that is mixed with water in an appropriate amount to produce plasticity when kneaded, rigidity when dried, and sintered when baked at high temperature. Specifically, as the thixotropic agent, at least one powder selected from the group consisting of kaolinite, fumed silica and bentonite may be used. In order to obtain the best effect, a mixture of fumed silica and bentonite in a weight ratio of 1: 1 is used . The thixotropic agent is preferably mixed with 1 to 2 parts by weight based on 100 parts by weight of the total of the main coating and the curing agent. If the thixotropic imparting agent is less than 1 part by weight, the flowability can not be controlled sufficiently, and the diameter can be made larger and the height can be made lower than that of the projections of the desired shape and size. If the amount is more than 2 parts by weight, The diameter of the protrusion may be smaller than the diameter of the protrusion.

The auxiliary additives are used to improve the physical properties of the plastic composition, and at least one of kaolin, sawdust, and fly ash may be used. Kaolin is a raw material based on kaolinite and halloysite, which helps maintain the shape of the protrusions produced. Sawdust is a by-product produced during the processing of wood such as cutting, polishing, and sandpaper, and can improve the abrasion resistance of the resulting protrusions. Fly ash can increase the strength of the generated protrusions as a remnant after burning the coal by pulverizing coal (passing through 70 to 80% of 200 mesh) in a thermal power plant. The auxiliary additive is preferably mixed in an amount of 1 to 2 parts by weight with respect to 100 parts by weight of the total of the main paint and the curing agent. If the amount of the auxiliary additive is less than 1 part by weight, the effect of the auxiliary additives such as shape retention, stiffness and abrasion resistance can not be obtained. If the amount is more than 2 parts by weight, Lt; / RTI >

일 실시예에 있어서, 도포단계(S20)는 돌출부가 형성될 지점에 플라스틱 조성물을 도포하는 단계로, 상술한 플라스틱 조성물을 도포한 후, 상온에서 경화할 수 있다. 도 2 및 도 3을 이용하여 보다 구체적으로 설명하면, 도포단계(S20)는 특정 지점에 플라스틱 조성물을 도포한 후, 상온에서 경화하여 복수 개의 원형 돌출부가 형성되는 차선을 형성할 수 있다. 이때, 원형의 돌출부는 지름(C)이 10~25mm이고, 높이(D)는 1~6mm인 것이 바람직하다. 또한, 복수 개의 동일한 원형 돌출부가 형성된 차선을 형성할 때, 길이방향(X)으로 인접한 원형 돌출부 간의 최단거리(A)는 5~40mm인 것이 바람직하고, 폭방향(Y)으로 인접한 원형 돌출부 간의 최단거리(B)는 5~20mm인 것이 바람직하다. 예를 들어, 150mm 폭의 차선을 형성할 때, 원형 돌출부의 지름은 25mm, 폭방향으로 원형 돌출부 간의 최단거리는 5mm로 형성될 수 있다. 이러한 범위는 도로의 폭 등에 따라 달라질 수 있으나, 150mm 폭의 차선을 형성할 시에는, 상기 크기 및 간격의 범위로 돌출부가 형성될 때, 재귀반사성이 극대화 되어 가장 우수한 시인성을 얻을 수 있을 뿐만 아니라 차량 운전자가 차선을 밟았을 때, 경각심을 고취시킬 수 있다. 즉, 지나치게 큰 돌출부를 형성하면 운전자에게 오히려 부담(주행)을 줄 수 있고, 돌출부 사이의 간격이 너무 클 경우에는 재귀 반사성이 떨어지는 등 운전자의 주의를 끌 수 없다.In one embodiment, the applying step S20 is a step of applying the plastic composition to the point where the projecting portion is to be formed, and after the plastic composition described above is applied, it may be cured at room temperature. 2 and 3, the applying step S20 can form a lane in which a plurality of circular protrusions are formed by applying the plastic composition at specific points and then curing at room temperature. At this time, it is preferable that the circular projection has a diameter (C) of 10 to 25 mm and a height (D) of 1 to 6 mm. It is preferable that the shortest distance A between the adjacent circular protruding portions in the longitudinal direction X is 5 to 40 mm when the lane in which the plurality of the same circular protruding portions are formed is preferable and the shortest distance A between the adjacent circular protruding portions in the width direction Y The distance B is preferably 5 to 20 mm. For example, when forming a lane of 150 mm in width, the diameter of the circular protruding portion may be 25 mm, and the shortest distance between the circular protruding portions in the width direction may be 5 mm. When the lane of 150 mm width is formed, when the protrusion is formed in the range of the size and the interval, the retroreflectivity is maximized and the most excellent visibility can be obtained. In addition, When the driver steps on the lane, he can raise awareness. In other words, if an excessively large protrusion is formed, the driver can be given more burden (running), and if the distance between the protrusions is too large, the retroreflectivity will be lowered,

일 실시예에 있어서, 살포단계(S30)는 돌출부 상부에 실란 코팅된 글라스 비드(유리알)을 살포하는 단계로, 야간에 차선의 시인성을 향상시킬 수 있다. 이때, 글라스 비드는 직경이 200~850㎛을 사용하는 것이 바람직하다. 특히, 상술한 플라스틱 조성물을 사용할 경우, 원형의 돌출부가 견고하게 형성되면서도 글라스 비드와 효과적으로 접착될 수 있으므로, 우천시 또는 야간에 시인성을 효과적으로 향상시킬 수 있다.In one embodiment, the spraying step S30 is a step of spraying silane-coated glass beads (glass beads) over the protrusions, thereby improving the visibility of the lane at night. At this time, the diameter of the glass beads is preferably 200 to 850 mu m. Particularly, when the above-described plastic composition is used, the circular protrusions can be firmly adhered to the glass beads while being firmly formed, so that the visibility can be effectively improved during rain or at night.
