Description
본 발명은 축광안료를 이용한 융착식 노면 표지용 도료에 관한 것으로, 더욱 상세하게는 도로의 표면에 일회 도포로 투터운 도막을 형성할 수 있으며, 내구성이 우수하여 수명이 길고, 야간이나 우천시에도 우수한 시인성을 나타내는 도막을 형성하는 축광안료를 이용한 융착식 노면 표지용 도료에 관한 것이다.
More particularly, the present invention relates to a paint for coating a surface of a road surface using a phosphorescent pigment. More specifically, the present invention relates to a paint for coating a surface of a road, And a phosphorescent pigment for forming a coating film showing visibility.
일반적으로 도로의 차선은 도로 주행중인 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 글라스 비드를 함유하는 페인트 조성물을 도포하거나, 또는 글라스 비드가 함유된 액제를 도색된 차선 위에 살포하여 차선 표면에 글라스 비드를 접착시킴으로써 재귀반사성을 향상시키고 있다.Generally, the lane of the road is used as a guide for guiding the vehicle so that the vehicle traveling in the road can be safely moved. In order to improve the lane visibility during the rainy season or at night, it is painted with a paint composition containing glass beads, After painting, the paint composition containing glass beads is coated on the lane before drying, or the glass bead is adhered to the lane surface by spraying the liquid containing the glass beads on the lane to improve the retroreflectivity.
이러한 도료로서 대표적인 것으로서 상온건조형 노면 표지용 도료, 수용성 노면 표지용 도료, 가열형 노면 표지용 도료, 융착식 노면 표지용 도료 조성물 및 상온 경화형 플라스틱 도료가 알려져 있으며, 정부는 KSM 6080로 규정하고 있다.As typical examples of such paints, there are known indoor surface drying paint, water-soluble road surface coating paint, heating type road surface marking paint, fusing type road surface marking paint composition and room temperature curing type plastic paint, and the government defines KSM 6080 .
특히, 융착식 도료 조성물은 석유 수지, 폴리에틸렌 왁스, 디-2-에틸헥실 프탈레이트와 같은 프탈레이트계 가소제, 탄산칼슘, 글라스 비드, 안정제, 이산화티타늄 및 EVA 등을 주성분으로 하는 조성물이 널리 사용되고 있다.Particularly, the fusion-type coating composition is widely used as a composition containing a phthalate plasticizer such as petroleum resin, polyethylene wax, di-2-ethylhexyl phthalate, calcium carbonate, glass beads, stabilizer, titanium dioxide and EVA as main components.
그러나, 종래에 융착식 도료는 바인더수지로 석유수지가 사용되었는데, 상기 석유수지는 시간이 경과함에 따라 크랙이 비교적 쉽게 발생하여 도로의 표면에 형성된 도막이 쉽게 손상되는 문제점이 있었다.However, conventionally, a petroleum resin has been used as a binder resin in the fusion-type paint, and the petroleum resin has a problem in that cracks are relatively easily generated with time and the coating film formed on the surface of the road is easily damaged.
또한, 종래에 도로용 도료는 야간이나 우천시에는 시인성이 저하되어 운전자로 하여금 불편함을 초례하거나 위험성에 노출되게 하는 문제점이 있었다.In addition, conventionally, there is a problem that the visibility of the road coating material is lowered at night or in the rainy season, causing the driver to inconvenience or to be exposed to danger.
한편, 물질의 광학현상 중 온도방사, 체렌코프 방사 이외의 발광현상을 총칭하여 루미네센스(Luminescence)라 하는데, 흔히 형광(Fluorescence)과 인광(Phosphorescence)으로 대별된다. 형광체는 인광체와 대비되어 순간적으로 발광현상을 나타내며, 강도가 현저히 온도의존성을 가지지 않는 발광부분을 칭하며, 시간적 변화는 반드시 지수함수적으로 나타나는데, 발광시간으로 볼 때, 비교적 단시간인 것으로 분류되나, 반드시 발광시간으로 구분되지는 않고 에너지원이 존재하는 동안 높은 휘도를 나타내는 것을 일컫는다.On the other hand, the luminous phenomena other than the temperature radiation and the cherenkov radiation during the optical development of the material are collectively called luminescence, and they are generally classified into fluorescence and phosphorescence. The phosphor refers to a light emitting portion that exhibits a luminescence phenomenon momentarily compared to a phosphor and has a strength that is not significantly temperature dependent. The temporal change always appears exponentially. It is classified as a relatively short time in terms of luminescence time It is not distinguished by the luminescence time and refers to a high luminance while the energy source is present.
또한, 인광체는 형광체와 대비되어 자극원을 제거하여도 발광이 잔존하는 것을 칭하는 것으로, 발광시간으로 형광체와 구별될 수 있으나 그 한계는 불명확하며, 온도나 환경에 의한 강도와 감쇄시간의 변화가 크고, 감쇄도 지수가 함수적이지 않은 경우가 많은데 축광안료가 대표적인 물질이다.
The phosphor is distinguished from the phosphor by the light emission time, but its limit is unclear, and the change in strength and attenuation time due to temperature or environment is large , And the attenuation index is often non-functional. The phosphorescent pigment is a typical material.
본 발명의 목적은 도로의 표면에 일회 도포로 투터운 도막을 형성할 수 있으며, 내구성이 우수하여 수명이 길고, 야간이나 우천시에도 우수한 시인성을 나타내는 도막을 형성하는 축광안료를 이용한 융착식 노면 표지용 도료를 제공하는 것이다.

이하에는, 본 발명의 바람직한 실시예와 각 성분의 물성을 상세하게 설명하되, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적인 사상 및 범주가 한정되는 것을 의미하지는 않는다.
Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.
본 발명에 따른 축광안료를 이용한 융착식 노면 표지용 도료는 바인더수지, 축광안료, 충전제, 열안정제 및 점도조절제로 이루어지며, 바인더수지 100 중량부, 축광안료 80 내지 100 중량부, 충전제 4 내지 10 중량부, 열안정제 2 내지 8 중량부 및 점도조절제 2 내지 6 중량부로 이루어지는 것이 바람직하다.
A coating composition for a road surface marking using a phosphorescent pigment according to the present invention is composed of a binder resin, a phosphorescent pigment, a filler, a heat stabilizer and a viscosity modifier, and comprises 100 parts by weight of a binder resin, 80 to 100 parts by weight of a phosphorescent pigment, 2 to 8 parts by weight of a heat stabilizer, and 2 to 6 parts by weight of a viscosity adjusting agent.
상기 바인더수지는 본 발명에 따른 축광안료를 이용한 융착식 노면 표지용 도료를 구성하는 각 성분들을 결속시키고, 접착성을 부여하는 역할을 하며, 도료가 도로에 도포되어 도막이 형성된 후에는 크랙이 발생하지 않도록 하는 역할을 한다.The binder resin binds each component constituting the painting surface coating paint using the phosphorescent pigment according to the present invention and imparts adhesiveness, and cracks are not generated after the paint is applied to the road and the coating film is formed .
이때, 상기 바인더수지는 수소첨가 석유수지로 이루어지며, 탄화수소의 함량이 15 내지 25%인 수서첨가 석유수지로 이루어지는 것이 바람직한데, 상기와 같이 탄화수소 등의 수소첨가 석유수지를 사용하게 되면, 종래에 단순 석유수지를 바인더수지로 사용했을 때 발생하는 도막의 크랙발생 문제를 해소할 수 있다.
At this time, it is preferable that the binder resin is made of a hydrogenated petroleum resin and is composed of a water-added petroleum resin having a hydrocarbon content of 15 to 25%. When the hydrogenated petroleum resin such as a hydrocarbon is used, It is possible to solve the problem of cracking of the coating film which occurs when a simple petroleum resin is used as the binder resin.
상기 축광안료는 80 내지 120 중량부가 함유되는데, 본 발명에 따른 축광안료를 이용한 융착식 노면 표지용 도료가 도로의 표면에 도포되고 난 후에, 야간이나 우천시에 시인성이 확보될 수 있도록 하는 역할을 한다.The phosphorescent pigment is contained in an amount of 80 to 120 parts by weight. The coating of the surface of the road using the phosphorescent pigment according to the present invention is coated on the surface of the road so that visibility can be ensured at night or rainy days .
또한, 상기 축광안료는 350 내지 450LUX의 빛을 받았을 때, 5 내지 10 밀리칸델라(MCD)의 휘도를 나타내는 것을 사용해야 하는데, 본 발명에서 사용하는 축광 안료는 소량의 희토류 원소, 바람직하게는 유로피늄(Eu), 가돌리늄(Gd), 디스프로슘(Dy), 터븀(Tb) 및 이터늄(Yb)으로 이루어진 군에서 선택된 희토류 원소가 도핑된 알카리토류 금속의 알루미나 성분의 복합물인 무기계 축광안료를 사용하되, 상기 알칼리토류 금속 알루미나 성분의 복합물로는 산화알루미늄과 산화칼륨, 산화스트론튬 및 산화마그네슘으로 이루어진 그룹에서 선택된 하나 이상의 염들의 복합체로서, Al2O3CaO, Al2O3MgO, SrAl2O4, SrAl2O4(OH) 또는 Al2O3CaOSrOB2O3 등과 같은 염들의 복합물을 사용할 수 있는데, 바람직하게 본 발명에서는 희토류 원소가 도핑된 알루미나 성분(Al2O3-SrO3-B2O3)의 축광 안료를 사용하는 것이 바람직하다. 상기의 성분으로 이루어진 축광안료는 히토류 원소가 도핑되어 잔광 휘도, 잔광 시간 및 내광성 등에 대한 축광 성능이 우수하다.In addition, the phosphorescent pigment should exhibit a luminance of 5 to 10 milli-candela (MCD) when light of 350 to 450 LUX is received. The phosphorescent pigment used in the present invention is a rare-earth element, Wherein the inorganic phosphorescent pigment is a complex of an alumina component of an alkaline earth metal doped with a rare earth element selected from the group consisting of Eu, Gd, Dy, Tb, and Yb, The composite of the alkaline earth metal alumina component is a composite of at least one salt selected from the group consisting of aluminum oxide and potassium oxide, strontium oxide and magnesium oxide, and is a composite of Al 2 O 3 CaO, Al 2 O 3 MgO, SrAl 2 O 4 , SrAl 2 O 4 (OH) or Al 2 O 3 CaOSrOB 2 O 3. Preferably, in the present invention, a rare earth element-doped alumina component (Al 2 O 3 -SrO 3 - B 2 O 3 ) phosphorescent pigment is preferably used. The phosphorescent pigment composed of the above-mentioned components is excellent in the phosphorescent performance against the afterglow luminance, afterglow time and light resistance by doping with a helium element.
상기의 성분으로 이루어진 축광안료가 함유된 도료는 낮동안 태양광 등으로부터 빛을 받은 후에 야간이나 우천시와 같이 어두운 상황에서 고휘도를 나타내기 때문에, 도로의 차선등에 적용하면 운전자의 안전을 도모할 수 있다. The coating material containing the phosphorescent pigment of the above-mentioned components exhibits high brightness under dark conditions such as nighttime or rainy days after receiving light from sunlight during the daytime, so that safety of the driver can be achieved by applying to the lane of the road .
상기 축광안료의 함량이 80 중량부 미만이면 상기의 효과가 미미하며, 상기 축광안료의 함량이 120 중량부를 초과하게 되면 축광효과는 크게 향상되지 않으면서 제조비용을 증가시키게 된다.When the content of the phosphorescent pigment is less than 80 parts by weight, the above-mentioned effect is insignificant. When the content of the phosphorescent pigment exceeds 120 parts by weight, the phosphorescent effect is not greatly improved but the manufacturing cost is increased.
특히, 상기 축광안료의 함량이 120 중량부를 초과하게 되면 본 발명에 따른 축광안료를 이용한 융착식 노면 표지용 도료의 휘도 감소율이 크게 향상되어 바람직하지 못하다.
In particular, when the content of the phosphorescent pigment exceeds 120 parts by weight, the reduction rate of luminance of the coating surface of the fused surface marking using the phosphorescent pigment according to the present invention is greatly improved.
상기 충전제는 4 내지 10 중량부가 함유되며, 상기 바인더수지에 균열이 발생하는 것을 억제하는 역할을 하는데, 중량평균 분자량이 10000 내지 20000인 폴리프로필렌으로 이루어지는 것이 바람직하다.The filler is contained in an amount of 4 to 10 parts by weight and inhibits the occurrence of cracks in the binder resin. The filler is preferably composed of polypropylene having a weight average molecular weight of 10,000 to 20,000.
상기와 같은 분자량을 나타내는 폴리프로필렌이 4 내지 10 중량부 함유되면 상기 바인더수지의 기계적 물성이 개선되어 도로에 도포되어 형성되는 도막에 균열발생을 억제할 수 있는데, 상기 충전제의 함량이 4 중량부 미만이면 상기의 효과가 미미하며, 상기 충전제의 함량이 10 중량부를 초과하게 되면 도료의 점도가 지나치게 증가하여 균일한 도막의 형성이 어렵고 제조비용을 증가시키게 된다.
When the polypropylene having a molecular weight as described above is contained in an amount of 4 to 10 parts by weight, the mechanical properties of the binder resin are improved, and cracking can be suppressed in the coating film formed on the road. When the content of the filler is less than 4 parts by weight , The effect is insignificant. If the content of the filler exceeds 10 parts by weight, the viscosity of the coating increases excessively, making it difficult to form a uniform coating film and increase the manufacturing cost.
상기 열안정제는 2 내지 8 중량부가 함유되며, 본 발명에 따른 축광안료를 이용한 융착식 노면 표지용 도료를 제조하는 과정에서 200℃ 내외의 온도에서 가열교반하는 과정을 거치는데, 상기의 과정에서 상기 바인더수지가 탄화되거나 열화되는 것을 억제하여 물성이 유지될 수 있도록 하는 역할을 한다.The heat stabilizer is contained in an amount of 2 to 8 parts by weight and is heated and stirred at a temperature of about 200 ° C. in the process of preparing a coating composition for a sealable surface marker using the phosphorescent pigment according to the present invention. Thereby preventing the binder resin from being carbonized or deteriorated to maintain physical properties.
상기 열안정제는 특별히 한정되지 않고, 상기 바인더수지에 혼합되어 열안정성을 부여할 수 있는 성분이면 어떠한 것이든 사용가능하나, 유기주석으로 이루어지는 것이 바람직하며, 한국특허출원 제10-1980-0001969호 등에 기재된 방법을 통해 제조된 것을 사용할 수 있다.The heat stabilizer is not particularly limited and any component that can be mixed with the binder resin to impart heat stability can be used. However, it is preferable that the heat stabilizer is composed of organotin, and Korean Patent Application No. 10-1980-0001969 Those produced through the described methods can be used.
상기 열안정제의 함량이 2 중량부 미만이면 상기의 효과가 미미하며, 상기 열안정제의 함량이 8 중량부를 초과하게 되면 상기의 효과는 크게 향상되지 않으면서 악취를 발생시키고, 제조비용을 증가시키게 된다.
If the content of the heat stabilizer is less than 2 parts by weight, the above effect is insignificant. If the content of the heat stabilizer exceeds 8 parts by weight, the above effect is not greatly improved but the odor is generated and the manufacturing cost is increased .
상기 점도조절제는 2 내지 6 중량부가 함유되며, 본 발명에 따른 축광안료를 이용한 융착식 노면 표지용 도료의 점도를 증가시키는 역할을 하는데, 특히, 도료를 제조하는 과정에서 상기 바인더수지가 빨리 끓게하여 제조과정의 효율성을 향상시키며, 도료의 점도를 증가시켜 도로의 표면에 도료를 도포하는 과정에서 도료를 2 밀리미터 이상의 두께로 도포하더라도 도료가 흘러내리지 않도록 하는 역할을 한다.The viscosity controlling agent is contained in an amount of 2 to 6 parts by weight and serves to increase the viscosity of the coating surface coating paint using the phosphorescent pigment according to the present invention. Particularly, in the course of preparing the paint, The efficiency of the manufacturing process is improved and the viscosity of the paint is increased to prevent the paint from flowing down even when the paint is applied to the surface of the road in a thickness of 2 mm or more.
일반적으로, 도료를 이용하여 노면의 표면에 형성할 수 있는 도막의 두께는 도료의 점도와 흐름성 등을 고려했을 때, 0.3 내지 0.5 밀리미터인데, 노면표시용으로 형성되는 도막의 경우 기계적 물성 등을 고려하여 2 밀리미터 정도의 두께를 나타내는 것이 바람직하다.Generally, the thickness of a coating film that can be formed on the surface of a road surface using a paint is 0.3 to 0.5 millimeters in consideration of the viscosity and flowability of the coating material. In the case of a coating film formed for road surface display, It is preferable to show a thickness of about 2 millimeters.
종래에는 상기와 같이 2 밀리미터의 도막을 형성하기 위해서 4 내지 7회에 걸쳐 도료를 바르고 건조하는 과정을 반복해야하기 때문에 공정의 효율성이 저하되었으나, 본 발명의 도료는 점도 향상으로 흐름현상이 개선되어 한번의 도포과정 만으로 2 밀리미터 두께의 도막을 형성할 수 있다.Conventionally, in order to form a coating film having a thickness of 2 millimeters as described above, the process of applying and drying the coating is repeated four to seven times, so that the efficiency of the process is lowered. However, A coating film having a thickness of 2 mm can be formed by a single application process.
이때, 상기 점도조절제는 폴리에틸렌왁스로 이루어지는 것이 바람직한데, 상기 점도조절제의 함량이 2 중량부 미만이면 상기의 효과가 미미하며, 상기 점도조절제의 함량이 6 중량부를 초과하게 되면 상기의 효과는 크게 향상되지 않으면서 도료의 점도가 지나치게 증가하여 도포과정의 효율성을 저하시킬 수 있다.
When the content of the viscosity modifier is less than 2 parts by weight, the effect is insignificant. When the content of the viscosity modifier exceeds 6 parts by weight, the effect is greatly improved The viscosity of the coating material may be excessively increased and the efficiency of the coating process may be deteriorated.

<표 1><Table 1>
위에 표 1에 나타낸 것처럼, 본 발명의 실시예 1 내지 2 및 비교예 1 내지 5를 통해 제조된 융착식 노면 표지용 도료는 휘도 기준을 모두 만족하는 것을 알 수 있다.
As shown in Table 1 above, it can be seen that the fusing type road surface marking paint prepared in Examples 1 to 2 and Comparative Examples 1 to 5 of the present invention satisfied all the brightness standards.
또한, 상기 실시예 1 내지 2 및 비교예 1 내지 5를 통해 제조된 융착식 노면 표지용 도료의 휘도감소율을 측정하여 아래 표 2에 나타내었다.In addition, the luminance reduction rate of the coating type surface coating paint prepared through Examples 1 to 2 and Comparative Examples 1 to 5 was measured and shown in Table 2 below.
{단, 휘도감소율은 융착식 노면 표지용 도료가 2 밀리미터의 두께로 도포된 시편을 제조하여 측정하되, ANSI(American National Standards Institute, 미국표준협회) 밝기의 기준에서 바로 비치는 햇빛을 축광조사 광원으로 채택하여 7시간 동안 조사하고, 광원을 차단한 후에 「피난유도선 성능인증 및 제품검사의 기술기준」에서 제시하고 있는 조건에서 휘도계(LS-100)의 측정각을 1°인 상태로 하여 표시부 전면 1m 거리에서 시간의 경과에 따라 측정하였다.(However, the luminance reduction rate is measured by preparing a specimen coated with a paint with a thickness of 2 millimeters for welding surface marking coating, and measuring the sunlight directly from the standard of ANSI (American National Standards Institute) After the light source is shut off, the measurement angle of the luminance meter (LS-100) is set to 1 ° under the conditions set forth in the "Technical Standards for Evacuation Guidance Performance Certification and Product Inspection" And measured at a distance of 1 m from the front as time elapses.
또한, 시간경과에 따른 휘도 변화에 대한 관계식은 와 의 직선관계로 식 1과 같이 표현될 수 있다.In addition, the relational expression for the luminance change over time can be expressed as Equation 1 by a linear relationship of and.
(식 1) (Equation 1)
여기서, LT = T분 후 휘도 값(mcd/㎡)Here, the luminance value (mcd / m < 2 >) after LT =
T = 측정 시간(min) T = measurement time (min)
a = 휘도감소율 a = luminance reduction rate
b = 초기 휘도 값(mcd/㎡) b = initial luminance value (mcd / m2)
위 식 1을 통한 초기시간(Ti)과 종료시간(Tf)의 휘도 관계식 다음과 같다.The luminance relation between the initial time (Ti) and the end time (Tf) through Equation (1) is as follows.
(식 2) (Equation 2)
(식 3) (Equation 3)
위의 식 2와 식 3을 정리하여 a를 계산하면 아래와 같은 식 4가 도출되며, 이 식을 이용하여 휘도감소율을 구할 수 있다.If a is calculated by summarizing the above Equation 2 and Equation 3, the following Equation 4 is derived, and the luminance reduction rate can be obtained using this equation.
(식 4) (Equation 4)
초기 휘도값은 1분과 2분 사이에 평균 감소율이 50% 이상으로 1분을 초기 휘도값으로하여 모형화시에는 관계식의 신뢰성이 떨어지기 때문에, 2분 후 측정 값을 초기 휘도 값으로 정하였고, 휘도 감소율은 「축광유도표지 및 축광위치표지에 대한 성능시험기술기준」의 최소 휘도 기준인 7m㏅까지 지속되는 휘도감소율을 비교분석 하였다.}
The initial luminance value was set as the initial luminance value at 1 minute and 2 minutes, and the initial luminance value was set at the initial luminance value at the rate of 1% The reduction rate was compared with the luminance reduction rate which lasted up to 7m 최소 which is the minimum luminance standard of the performance test standard for the phosphorescence indicator and the phosphorescent lamp.

As shown in Table 2 above, the coating type surface marking paint using the phosphorescent pigment prepared in Examples 1 and 2 of the present invention was applied to the surface of the fused surface marking paint using the phosphorescent pigment prepared in Comparative Examples 1 to 5 The brightness reduction rate is lower than that of the conventional example, so that the visibility is maintained for a long time at night.
또한, 상기 실시예 1을 통해 제조된 축광안료를 이용한 융착식 노면 표지용 도료와 비교예 6을 통해 제조된 융착식 노면 표지용 도료의 휘도변화를 측정하여 아래 표 3에 나타내었다.Table 3 below shows the change in luminance of the coating surface of the fusion-type road marking paint using the phosphorescent pigment prepared in Example 1 and the coating surface of the fusion-type road marking surface prepared in Comparative Example 6.
{단, 휘도변화는 융착식 노면 표지용 도료가 2 밀리미터의 두께로 도포된 시편을 제조하여 측정하되, 2016년 1월 20일 경기도에 위치한 대동안전(주) 사내에서 자연광을 12시간 조사한 후에 「피난유도선 성능인증 및 제품검사의 기술기준」에서 제시하고 있는 조건에서 휘도계(LS-100)의 측정각을 1°인 상태로 하여 표시부 전면 1m 거리에서 시간의 경과에 따라 측정하였다.}
(However, the change in luminance was measured by preparing a specimen coated with a coating of a welding surface marking of 2 mm in thickness and measuring natural light for 12 hours in Daedong Safety Co., Ltd., located in Gyeonggi Province on January 20, 2016, (LS-100) was measured at a distance of 1m from the front face of the display unit with the measurement angle of 1 degree at the luminance meter (LS-100) under the conditions specified in "Technical Standard for Certification of Evacuation Line Performance and Product Inspection".
<표 3><Table 3>
위에 표 3에 나타낸 것처럼, 본 발명의 실시예 1을 통해 제조된 도료는 비교예 6을 통해 제조된 도료에 비해 우수한 휘도를 나타내며, 시간이 경과해도 휘도 향상효과가 유지되며, 아래 도 2에 나타낸 것처럼, 암흑조건에서 우수한 시인성을 나타내는 것을 알 수 있다.
As shown in Table 3 above, the paint prepared in Example 1 of the present invention exhibits excellent luminance compared to the paint prepared in Comparative Example 6, and the luminance improving effect is maintained even after a lapse of time, As a result, it can be seen that it exhibits excellent visibility in the dark condition.
따라서, 본 발명에 따른 축광안료를 이용한 융착식 노면 표지용 도료는 도로의 표면에 일회 도포로 2 밀리미터 이상의 도막을 형성할 수 있으며, 내구성이 우수하여 수명이 길고, 야간이나 우천시에도 우수한 시인성을 나타내는 도막을 형성한다.Therefore, the coating material for a fusible road surface marking using the phosphorescent pigment according to the present invention can form a coating film of 2 mm or more on a surface of a road with a single application and exhibits excellent durability and long life and excellent visibility even at night or rainy days Thereby forming a coating film.
