Description

도로표지용 도료조성물{PAINT COMPOSITION FOR ROAD MARKING}{PAINT COMPOSITION FOR ROAD MARKING}

본 발명은 도로표지용 도료조성물에 관한 것으로, 특히, 도로표지가 저점도, 저도막 두께에서도 내크랙성, 내구성이 향상되며, 입경의 크기가 서로 다른 글라스비드가 도로표지의 두께 내부에 순차적 또는 계층적으로 침강되게 하여 마모에 의한 글라스비드의 순차적 노출에 의한 빛의 반사에 의해 육안식별을 용이하게 하고, 자체적인 색깔을 가지는 글라스비드가 빛에 반사되면서 유광의 빛을 반사하게 됨으로써, 글라스비드에 의해서 도로표지의 색상을 원거리에서 더욱 선명하게 식별할 수 있게 하는 도로표지용 도료조성물에 관한 것이다.The present invention relates to a coating composition for road marking, and more particularly, it relates to a coating composition for road marking which is improved in crack resistance and durability even at low viscosity and low film thickness, and that glass beads having different sizes are sequentially So that the naked eye identification is facilitated by the reflection of light due to the sequential exposure of the glass beads due to abrasion, and the glass beads having their own colors are reflected by the light, The present invention relates to a paint composition for road marking, which enables a color of a road marking to be more clearly distinguished from a distance.

일반적으로 포장된 도로에서는 주행방향을 표시하는 차선, 보행자의 안전을 위한 횡단보도, 목적지 정보, 진행방향 유도, 안전을 위한 제한속도 등을 표시하는 도료표지들이 있고, 이와같은 도로표지용으로 여러 가지 도료들이 목적에 따라 다양한 종류가 개발되어 사용되고 있다.Generally, on packed roads, there are paint markings indicating lane marking direction, pedestrian crossing for pedestrian safety, destination information, direction of travel, speed limit for safety, etc., Various kinds of paints have been developed and used according to purposes.

도로의 차선은 도로 주행 중인 차량이 안전하게 이동할 수 있도록 방향을 안내하는 지시선 용도로 사용되고 있으며, 최근 우천시나 야간 중의 차선 시인성을 향상시키기 위해 글라스 비드가 함유된 페인트 조성물로 도색하거나, 또는 차선을 도색한 다음, 건조되기 전에 차선 위에 재귀반사비드(bead)를 함유하는 페인트 조성물을 도포하거나, 또는 글라스 비드가 함유된 액체를 도색된 차선 위에 살포하여 차선 표면에 글라스 비드를 접착시킴으로써 재귀반사성을 향상시키고 있다.The lane of the road is used as a guide for guiding the direction of the vehicle so that the vehicle traveling on the road can be safely moved. In order to improve the lane visibility during the rainy or nighttime, it is painted with a paint composition containing glass beads, Next, the paint composition containing the bead is applied onto the lane before drying, or the glass bead is adhered to the lane surface by spraying the glass bead-containing liquid onto the painted lane to improve the retroreflectivity .

사용되는 도로표지용 도료조성물로는 유성 도로표지용 도료, 수성 도로표지용 도료, 융착식 도로표지용 도료, 상온식 페인트 도로표지용 도료가 대표적이다.Examples of the road marking paint composition used are oil-based road marking paints, water-based road marking paints, fusing road marking paints, and room temperature painted road marking paints.

유성 도로표지용 도료는 융착식 도로표지용 도료에 비해 시공되는 자재의 두께가 얇아 마모층이 적거나 건조의 시간이 길어 차량통행이 빈번한 도로일 경우 시공의 어려움이 크고, 스프레이 작업시 비산에 의한 2차 오염을 유발하며, 포장 용기 및 잔량의 폐기문제 등 환경적인 유해성이 높다는 단점이 있으며, 악취가 심하여 주변환경에도 유해하므로 작업자에게 특별한 주의가 요구된다.The paint for the oil-based road marking is difficult to apply in the case of a road with frequent vehicle traffic because the thickness of the material to be applied is thin compared to the coating type of road marking paint and the wear layer is small or the drying time is long. It causes secondary pollution, disadvantages such as disposal of packing containers and residual quantity, high environmental hazard, and it is harmful to surrounding environment due to bad odor.

수성 도로표지용 도료는 수성에멀전 수지에 물이나 안료 등을 혼합하여 액상으로 제조되며, 수성 제품이라는 점에서 주위 시공 환경(온도나 습도)에 영향을 받고, 건조시간이 느리기 때문에 시공할 때 제약을 받는다. 역시 포장용기와 잔량의 폐기 문제 및 비산 등 환경적으로 유해하다는 단점이 있으며, 수성에멀전 수지이므로 마모성과 휘도가 약한 단점이 있다.Waterborne road marking paints are made by mixing water-based emulsion resin with water or pigment, and are made into a liquid form. Since they are water-based products, they are affected by the ambient environment (temperature and humidity) and are slow in drying time. Receive. Also there is disadvantage that it is environmentally harmful such as disposal of packing container and remaining amount and scattering, and there is a disadvantage that it is weak in abrasiveness and brightness because it is an aqueous emulsion resin.

융착식 도로표지용 도료는 열가소성 수지에 안료나 글라스비드 등을 혼합한 것으로, 분말형태로 제조되어 현장에서 시공시 1차 용해조에서 용해시킨 후 2차 시공기에 옮겨서 뿌려주는 방식으로 작업이 수행됨에 따라 도심지와 혼잡한 도로의 통행 제한을 최소화하면서 시공할 수 있는 방법으로 사용되고 있다.The paint for road marking is a mixture of thermoplastic resin and pigment or glass bead. It is manufactured in powder form and dissolved in the first melting tank when it is applied in the field and then transferred to the second construction machine. It is being used as a way to construct construction while minimizing the traffic restrictions of downtown and congested roads.

글라스 비드를 조성물에 배합하여 사용하는 경우, 조성물 중에서 글라스비드가 쉽게 침강하기 때문에 시공 현장에서 다시 가열, 교반하여 사용하지 않으면 안되고, 이와 같은 침강, 고형화를 방지하고자 스테아린산이나 합성 왁스 등을 사용하였으나, 침강 방지의 효과가 그다지 만족스럽지 못하고, 더 나아가 상당 시간이 지난 후에는 조성물 전체가 고형화되어 사용할 수 없게 되고, 이를 사용하는 장비/장치도 그의 일부를 교체하지 않으면 안 되는 등 문제가 있으므로 이러한 문제를 해결하지 않으면 안 되었다.When the glass beads are used in combination with the composition, since glass beads easily precipitate in the composition, they must be heated and stirred again at the construction site, and stearic acid or synthetic wax is used to prevent sedimentation and solidification. However, The effect of sedimentation prevention is not so satisfactory, and furthermore after a considerable time, the entire composition becomes solidified and becomes unusable, and there is a problem that the equipment / I had to solve it.

또한, 기존의 도로표지용 도료는 그 두께가 얇아 시공할 때에 도막위에 뿌려놓은 글라스비드가 쉽게 마모되어 짧은 기간에도 휘도를 잃게 될 수가 있으며, 특히 비가오는 야간에는 차선을 구분하기가 어려우며 도면보다 오히려 마찰계수가 감소하여 자동차의 미끄러짐을 유발할 뿐만 아니라 보행자의 안전한 보행을 저해하는 문제가 있었다.In addition, since the conventional road marking paint is thin, the glass beads sprayed on the coated film can be easily worn out and the brightness may be lost even in a short period of time. Especially, in the case of rainy night, it is difficult to distinguish the lane, The coefficient of friction is reduced to cause slippage of the automobile and also inhibits safe walking of the pedestrian.

뿐만 아니라, 자동차의 타이어와의 반복 마찰로 인해 경시적으로 차선이 마모되어 도색 후 1년이 경과하면, 탈리가 심하여 매년 다시 도색해야 하는 등 유지 보수 비용의 증가로 경제적 손실이 가중되고, 또한 운전자의 도로 이용에서의 불편함이 더하여지고 있다.In addition, when the lane is worn over time due to repetitive friction with the tires of the vehicle and the year after the paint has passed, the tearing is severe and the annual maintenance cost is increased and the economic loss is increased, Of the road use is added to the inconvenience.

특히, 주간의 경우라도 경고, 주의, 휴식 등을 표시하는 차선이 고속으로 주행하던 자동차 운전자에게는 원거리에서의 차선 등의 색상이 명확하게 드러나지 않는 문제점이 있는데, 이러한 문제점은 조성물에 포함되는 안료에 의하여 그 식별력이 의존되기 때문으로서, 운전자는 차선과 일정거리 이내로 진입된 후에야만 식별이 되므로, 주, 야간 모두의 경우에도 차선의 식별이 항상 용이하게 이루어질 수 있도록 할 필요성이 있다.In particular, even in the case of a daytime, a driver of a vehicle traveling at a high speed in a lane indicating a warning, an attention, a rest, etc., has a problem in that the color of the lane in the distance is not clearly displayed. It is necessary to ensure that the lane can always be easily identified even in the case of both the main and the night since the discrimination is dependent only upon the driver entering the lane within a certain distance.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 조성물이 혼합될때 서로 다른 입경의 글라스비드가 혼합되게 함으로써, 차선작업 시 침강되는 속도에 의하여 침강되는 글라스비드와 일정부분 표면에 노출되는 글라스비드와 혼합물 중간에 포함되는 글라스비드가 계층을 유지할 수 있도록 함으로써, 자동차에 의한 차선마모에도 새로운 글라스비드가 노출되게 함으로써, 휘도가 유지될 수 있게 하며, 특히, 글라스비드 자체가 색상을 가질 수 있는 상태에서 투명도와 휘도가 유지되게 함으로써, 주, 야간은 물론 우천시에도 차선의 식별이 용이하게 이루어지게 하여 안전사고의 위험을 사전에 예방하고자 하는 도로표지용 도료조성물을 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the above-mentioned problems, and it is an object of the present invention to provide a glass bead which is settled by a settling velocity in a lane work and a glass bead And the glass beads contained in the middle of the mixture can maintain the layer, so that the new glass beads are exposed to the lane wear due to the automobile, so that the brightness can be maintained.

본 발명에 따른 도로표지용 도료조성물은 고무계열 바인더 수지 10 ~ 30 중량%, 실리카 5 ~ 25 중량%, 유색, 투명 또는 반투명한 유리재질로 이루어진 칼라 글라스비드 10 ~ 25 중량%, 착색안료 3 ~ 10 중량%, 탄산칼슘 5 ~ 25 중량%, 산화방지제 0.3 ~ 5 중량%, 산화안정제 오일 2 ~ 3 중량%, 에틸렌 폴리머 3 ~ 8 중량%를 포함한다.The coating composition for road marking according to the present invention comprises 10 to 30% by weight of a rubber-based binder resin, 5 to 25% by weight of silica, 10 to 25% by weight of colored glass beads made of a colored, transparent or translucent glass, 5 to 25% by weight of calcium carbonate, 0.3 to 5% by weight of an antioxidant, 2 to 3% by weight of an oxidation stabilizer oil and 3 to 8% by weight of an ethylene polymer.

본 발명에 따른 도료표지용 도료조성물 중 고무계열 바인더 수지는 재료에 유연성을 부여하는 재료인 SBS(Styrene Butadiene Styrene, '삼중블록 공중합체')가 주요 재료로 만들어진 열가소성 수지이다.Among the coating composition for paint marking according to the present invention, the rubber series binder resin is a thermoplastic resin made of SBS (Styrene Butadiene Styrene, 'triblock copolymer'), which is a material imparting flexibility to a material, as a main material.

본 발명에서 사용하는 고무계열 바인더 수지는 포장면과의 강한 접착성을 부여하는 초산비닐수지, 가공 및 시공시 재료의 용융 분산성을 증진시키는 각종 보조재와 내후성 향상을 위한 UV 안정제 등이 포함될 수 있다.The rubber-based binder resin used in the present invention may include a vinyl acetate resin that imparts strong adhesion to the packaging surface, various auxiliary materials for improving the melt-dispersibility of the material during processing and construction, and a UV stabilizer for improving weatherability .

상기 고무계열 바인더 수지는 여러 재료들과 상용성이 원활하여 도막을 견고하게 부착시켜주는 역할을 하고, 기존 융착식 석유화학수지나 로진타입의 융착식 도료보다 고무성질의 유연성이 있으며, 강한 자외선에도 크랙이 발생하지 않으며,친환경적이고 부착성, 내마모성, 고휘도성이 우수한 접착제 기능을 한다.The rubber-based binder resin has good compatibility with various materials and firmly adheres to the coating film. It has rubber property flexibility than conventional fusion-type petrochemical resin or rosin-type fusion-type paint, It does not cause cracks, and is an environmentally friendly adhesive functioning excellent in adhesion, abrasion resistance, and high brightness.

상기 고무계열 바인더 수지는 도로표지용 도료조성물 전체 100 중량%에 대하여 10 ~ 30 중량% 범위로 사용할 수 있으며, 10 중량% 미만이면 도로표지의 도막이 얇아져서 부착성이 떨어지고 조성물의 물성을 저해하는 문제점이 있고, 30 중량%를 초과하면 도막의 두께가 두꺼워져 글라스비드가 계층을 형성하는 글라스비드라도 표면에 노출되지 못하여 휘도의 문제점이 발생할 수 있다.The rubber-based binder resin may be used in an amount ranging from 10 to 30% by weight based on 100% by weight of the entire road marking paint composition. When the amount is less than 10% by weight, the coating film of road marking becomes thin, If it is more than 30% by weight, the thickness of the coating film becomes thick, and even a glass bead having a layer of glass beads may not be exposed to the surface, resulting in a problem of luminance.

본 발명에서 사용하는 실리카는 탄산칼슘과 함께 사용되어 도료조성물이 경화된 후에 도막의 내구성을 증대시켜 내마모성을 높이면서 도로표지의 시인성과 색상기능을 유지할 수 있으며, 특히, 도막의 경도 또는 뭉게짐을 방지하는 기능을 수행하는 것으로서, 본 발명에서는 도로표지용 도료조성물 전체 100 중량%에 대하여 5 ~ 25 중량% 범위내에서 탄산칼슘을 혼합하여 사용할 수 있으며, 5 중량% 미만으로 사용하면 도막의 견고성이 저하되고 25 중량%를 초과하면 점도가 높아져 작업성이 나빠지며, 내알칼리성이 저하되는 등 유연성과 부착성에 문제점이 생길 수 있다.The silica used in the present invention is used together with calcium carbonate to increase the durability of the coating film after the coating composition is cured, thereby enhancing the wear resistance and maintaining the visibility and hue of the road marking. Especially, In the present invention, calcium carbonate may be mixed in an amount of 5 to 25% by weight based on 100% by weight of the total of the road marking paint composition. When the amount is less than 5% by weight, If it is more than 25% by weight, the viscosity becomes high and the workability is deteriorated, and the alkali resistance is lowered, which may cause problems in flexibility and adhesion.

본 발명에서 사용하는 글라스비드는 고휘도를 가진 원형의 유리 알갱이 코팅을 한 것으로서 휘도를 오래 보전하면서 특히 야간에 자동차의 전조등 불빛에 반사성이 좋아 운전자나 보행자가 육안으로 쉽게 도로표지를 인식할 수 있게 된 것이다.The glass beads used in the present invention are circular glass grains coated with a high brightness, and are excellent in reflectivity to the light of a headlight of a car at night, while maintaining brightness for a long time, so that a driver or a pedestrian can easily recognize a road mark with the naked eye will be.

특히, 종래의 글라스비드는 투명한 유리 알갱이를 사용하였으나, 본 발명에서는 자체적으로 색상을 갖추고 있는 유리 알갱이를 글라스비드로 채택한 것으로서, 차선의 색상에 맞추어 글라스비드의 색상도 선택적으로 채택할 수 있으며, 이에 따라, 착색안료에 의한 육안식별은 물론 글라스비드에 의한 색상의 반사성에 의하여 운전자나 보행자가 육안으로 도로표지를 용이하게 식별할 수 있게 한다.Particularly, in the conventional glass beads, transparent glass grains are used. However, in the present invention, glass grains having their own colors are adopted as glass beads, and the color of the glass beads can be selectively adopted according to the color of the lane. Accordingly, it is possible for the driver or the pedestrian to easily identify the road mark by the naked eye by the colored pigment and the reflectivity of the color by the glass bead.

본 발명에서는 도로표지용 도료조성물 전체 100 중량%에 대하여 10 ~ 25 중량% 범위로 칼라 글라스비드를 사용할 수 있으며, 10 중량% 미만이면 야간 시인성 효과가 저하되는 문제점과 지속적인 고휘도를 유지하는데 문제점이 나타날 수 있고, 25 중량%를 초과하면 시인성의 효과는 증대되지 않고 오히려 도료 작업성이 나빠지고 도료의 특성인 유연성의 저하 및 크랙이 발생되며 재귀반사율이 저하되는 문제점이 발생할 수 있으며, 특히, 다른 성분들이 감소하여 도막의 부착성이 떨어지는 문제점이 나타날 수 있다.In the present invention, color glass beads may be used in an amount of 10 to 25% by weight based on 100% by weight of the entire road marking paint composition. If the amount is less than 10% by weight, the effect of night visibility deteriorates, If the content is more than 25% by weight, the effect of the visibility is not increased but rather the workability of the paint is deteriorated, the flexibility of the paint, the cracks, and the retroreflectivity may be lowered.

The glass beads can be selected and used by mixing 25 to 28% by weight of glass beads having a particle diameter of 100 to 299 μm and glass beads 30 having a particle size of 300 to 599 μm To 35% by weight and glass beads having a particle diameter of 600 to 850 탆 in a mixed amount of 38 to 45% by weight, when they are mixed with a coating composition and are applied by road marking, Therefore, when the road mark is cured, the glass bead having a particle diameter of 600 to 850 μm is settled close to the bottom surface, and the glass bead having a particle size of 300 to 599 μm is cured before the bottom surface is settled. Since the phosphorus beads are cured in a state of being exposed to the skin or settled down to the skin, even if the road mark is worn out, the sequentially settled glass beads are irregularly reflected in the light, It will be able to facilitate the visual identification of the driver.

특히, 난반사 시 유색(예를 들면, 노랑, 흰색, 빨강, 파랑 등)의 빛이 난반사되기 때문에 주간 또는 야간에도 용이한 식별이 가능하게 하는 장점을 가진다.In particular, since the light of color (for example, yellow, white, red, blue, etc.) is irregularly reflected when diffused reflection, it has an advantage of being able to easily identify during daytime or nighttime.
