Description

고무계열 바인더 수지를 이용한 용융형 도로표지용 도료조성물 및 이의 제조방법{PAINT COMPOSITION FOR ROAD MARKING AND MANUFACTURING METHOD THEREOF}Technical Field [0001] The present invention relates to a paint composition for a road marking using a rubber-based binder resin and a method for producing the same,

본 발명은 도로표지용 도료조성물에 관한 것으로, 특히 고무계열의 바인더 수지를 이용하여 도로에 도포하는 용융형 도로표지용 도료조성물에 관한 것이다.
TECHNICAL FIELD The present invention relates to a paint composition for road marking, and more particularly to a paint composition for road marking applied on a road using a rubber-based binder resin.

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.

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 아크릴이나 알키드 같은 유기합성 수지에 유기용제 및 안료를 혼합하여 액상으로 제조되는데, 휘발성유기화합물의 함량이 높아 환경적 유해인자가 되고 있다. Oil-based road marking paints are made by mixing organic solvents and pigments with organic synthetic resins such as acryl and alkyd, and they are in the form of liquid, which is an environmental harmful factor because of the high content of volatile organic compounds.

또한 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.In addition, coatings for oil-based road marking are more difficult to apply in the case of roads with frequent vehicle traffic because the thickness of materials to be applied is thinner than that of fusing road marking coatings and there is less wear layer or longer drying time. And there are disadvantages such as disposal of packing containers and residual quantity, high environmental harmfulness, and special care is required to the operator because it is harmful to surrounding environment because of 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.

일반 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 general welding type road marking paint is a mixture of thermoplastic resin and pigment or glass bead. It is manufactured in powder form, dissolves in the first melting tank when it is applied in the field, and then transferred to the second construction machine. Therefore, it is used as a method of constructing with minimizing the traffic restriction of downtown and congested roads.

이러한 종래의 융착식 도로표지용 도료는 분말제품이므로 용융기에 넣을때 분진이 날려서 작업자의 건강과 주변환경에 좋지 않으며 시공후에도 마모성과 균열, 박리 현상이 발생하기 쉬워 시인성이 떨어지고 재시공이 어려운 문제점이 있었다.Such a conventional welding type road marking paint is a powder product, so dust is blown when it is put into a melting machine, which is not good for the health and environment of the worker, and abrasion, cracking and peeling phenomenon easily occur after the construction, and visibility is low and rework is difficult .

또한, 기존의 상온식 페인트 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 paint for road surface paint at room temperature is thin, the glass beads sprayed on the coating film can easily be worn out during the construction, resulting in loss of brightness even in a short period of time. The coefficient of friction is reduced rather than the figure, which causes slippage of the automobile and hinders the safe walking of the pedestrian.

The present invention also provides a paint composition for road marking comprising 25 to 35% by weight of a rubber-based binder resin, 2 to 5% by weight of an ethylene polymer, 2 to 3% by weight of an oxidation stabilizer oil, 8 to 16% To 33% by weight of an inorganic filler and 15 to 30% by weight of an inorganic filler into a mixer to prepare a mixture, wrapping the mixture in a wrap of EVA material while weighing the mixture by automatic opening and closing, and melting the packaged mixture by a melting machine .

본 발명은 고무계열의 바인더 수지를 이용한 용융형 도로표지용 도료조성물은 기존 융착식 도료조성물의 장점들은 그대로 유지하면서도 균열과 박리문제가 발생하지 않고, 내마모성과 내후성이 높으며, 고휘도를 장기적으로 유지함에 따라 우천시에 운전자나 보행자의 시인성을 크게 높일 수 있는 효과가 있다.The present invention relates to a paint composition for road marking using a rubber-based binder resin, which is excellent in abrasion resistance and weathering resistance without causing cracking and peeling problems while maintaining the advantages of the existing fusion-type paint composition, Accordingly, there is an effect that the visibility of the driver or the pedestrian can be greatly increased in the rain.

또한, 기존의 도료보다 고무성질의 유연성이 있고 오랜시간 강한 자외선의 노출에도 크랙이 발생하지 않으며, 포장된 상태에서 그대로 용융기에 투입하여 사용함에 따라 시공시 분진이 날리지 않아 친환경적인 효과가 있다.
In addition, it has more rubber property flexibility than conventional paints, cracks do not occur even after exposure to strong ultraviolet rays for a long time, and dust is not sprayed when put into a melter as it is packaged.

이하에서는 본 발명의 바람직한 실시 예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail.

본 발명의 도로표지용 도료조성물은 고무계열 바인더 수지, 에틸렌 폴리머, 산화안정제 오일, 안료, 글라스비드, 무기충전제를 혼합하여 제조하게 된다.The coating composition for road marking of the present invention is prepared by mixing a rubber-based binder resin, an ethylene polymer, an oxidation stabilizer oil, a pigment, a glass bead and an inorganic filler.

고무계열 바인더 수지는 재료에 유연성을 부여하는 재료인 SBS(Styrene Butadiene Styrene, '삼중블록 공중합체')가 주요 재료로 만들어진 열가소성 수지이다.The rubber-based binder resin is a thermoplastic resin made of SBS (Styrene Butadiene Styrene, 'Triblock copolymer'), which is a material that imparts flexibility to materials.

본 발명에서 사용하는 고무계열 열가소성 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 thermoplastic 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 열가소성 수지는 여러재료들과 상용성이 원활하여 도막을 견고하게 부착시켜주는 역할을 하고, 기존 융착식 석유화학수지나 로진타입의 융착식 도료보다 고무성질의 유연성이 있으며, 강한 자외선에도 크랙이 발생하지 않는다. 또한 친환경적이고 부착성, 내마모성, 고휘도성이 우수한 접착제 기능을 한다.The rubber-based thermoplastic resin has good compatibility with various materials and firmly adheres to the coating film. The rubber-based thermoplastic resin is more flexible than the conventional fusion-type petrochemical resin or rosin-type fusion-type coating material, Cracks do not occur. It is environmentally friendly and has an adhesive function that is excellent in adhesion, abrasion resistance and high brightness.

고무계열 열가소성 수지는 전체 도료조성물에서 25~35중량% 범위로 사용할 수 있으며, 25중량% 미만이면 도로표지의 도막이 얇아져서 부착성이 떨어지고 조성물의 물성을 저해하는 문제점이 있고, 35중량%를 초과하면 도막의 두께가 두꺼워져 글라스비드가 묻힘으로서 휘도의 문제점이 발생할 수 있다.The rubber-based thermoplastic resin can be used in an amount ranging from 25 to 35% by weight in the entire coating composition, and if it is less than 25% by weight, the coating film of the road marking becomes thinner and adherence is deteriorated and the physical properties of the composition are impaired. The thickness of the coating film becomes thick, so that the glass beads are buried and a problem of brightness may occur.

에틸렌 폴리머는 저밀도 에틸렌 중합체로서, 내마모성과 인장강도가 우수하여 도막의 유연성과 끈적끈적한 것을 최소화시키면서 도막의 균열을 감소시키는 역할을 하는 것이며, 본 발명에서는 도료조성물의 2~5중량% 범위내에서 에틸렌 폴리머를 혼합하여 사용한다.The ethylene polymer is a low-density ethylene polymer which is excellent in abrasion resistance and tensile strength, and serves to reduce cracks in the coating film while minimizing the flexibility and stickiness of the coating film. In the present invention, Polymers are mixed and used.

에틸렌 폴리머가 2중량% 미만으로 사용되면 도막의 유연성저하로 크랙현상이 일어날 수 있으며, 5중량%를 초과하면 도막의 견고성이 부족하여 시공 후 자동차 타이어 자국이 나타날 수 있다.When the ethylene polymer is used in an amount of less than 2% by weight, cracking may occur due to a decrease in flexibility of the coating film. If the amount of the ethylene polymer is more than 5% by weight, the hardness of the coating film is insufficient.

산화안정제 오일은 고도로 정제된 파라핀, 나프렌 기유를 원료로 하여 인화점이 280℃의 내성을 가지도록 한 것을 사용하며, 장시간 사용에도 빛과 열에 대한 변색과 오염이 적으며 수분리성이 우수하여 물 혼입시 유화를 일으키지 않는다.Oxidation stabilizer oil uses highly refined paraffin and naphrenic base oil as raw materials and has a flash point of 280 ° C. It is resistant to discoloration and contamination due to light and heat for a long time and has excellent water repellency. It does not cause oil emulsions.

본 발명에서는 산화안정제 오일을 도료조성물 전체 중량의 2~3중량% 범위로 사용할 수 있으며, 2중량% 미만이면 색상과 산화안정성에 문제점이 있고, 3중량%를 초과하는 경우는 도막이 오염되는 문제점이 있을 수 있다.In the present invention, the oxidation stabilizer oil may be used in an amount of 2 to 3% by weight based on the total weight of the coating composition. If less than 2% by weight, there is a problem in color and oxidation stability, and if it exceeds 3% by weight, Can be.

안료는 도로표지용 도료조성물의 색상을 부여함으로써 시각적 효과를 부여하는 기능을 하며, 소정의 색상에 따라 적절한 안료를 선택하여 사용할 수 있다. The pigment functions to give a visual effect by imparting the color of the road marking paint composition, and a suitable pigment can be selected and used according to a predetermined color.

본 발명에서 안료는 도료조성물 전체 중량의 8~16중량% 범위로 사용할 수 있으며, 8중량% 미만이면 도로표지용으로 도포될 경우 색상이 선명하지 못하고, 16중량%를 초과하면 도막의 부착성을 저해하는 문제가 있을 수 있다.In the present invention, the pigment may be used in a range of 8 to 16% by weight of the total weight of the coating composition. When the coating is applied for road marking, the color is not clear. If it exceeds 16% by weight, There may be a problem of inhibiting.

글라스비드는 고휘도를 가진 원형의 유리알에 코팅을 한 것으로서 휘도를 오래보전하면서 특히 야간에 자동차의 전조등 불빛에 반사성이 좋아 운전자나 보행자가 육안으로 쉽게 도로표지를 인식할 수 있게 된다.The glass bead is coated with a round glass bulb with a high brightness, and it has a high reflectivity to the light of the headlight of a car, especially at night, while allowing the driver or the pedestrian to easily recognize the road mark with the naked eye.

본 발명에서는 글라스비드를 도료조성물 전체 중량의 23~33중량% 범위로 사용할 수 있으며, 23중량% 미만이면 지속적인 고휘도를 유지하는데 문제점이 나타날 수 있고, 33중량%를 초과하면 다른 성분들이 감소하여 도막의 부착성이 떨어지는 문제점이 나타날 수 있다.In the present invention, the glass beads can be used in the range of 23 to 33 wt% of the total weight of the coating composition. If it is less than 23 wt%, problems may occur in maintaining high brightness. When the content is more than 33 wt% It is possible that a problem of poor adhesion may occur.

무기충전제는 1800~2000℃의 철 용해시 나오는 제강 슬러그를 300~500㎛ 크기의 미립자 형태로 분말화한 것과 탄산칼슘을 사용하며, 실리카, 백동석 등을 포함하여 사용할 수도 있다. The inorganic filler is prepared by pulverizing steel making slag from iron melting at 1800 to 2000 ° C in the form of fine particles having a size of 300 to 500 μm, and using calcium carbonate, including silica and dolomite.
