Abstract
Description
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.
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.
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 .
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.
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.
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.
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.
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.
The object of the present invention is to provide a method for producing a coating film for a fused surface marking using a phosphorescent pigment which can form a coating film on the surface of a road with a single application and which has a long durability and a long life and forms a coating film having excellent visibility even at night or in rain Thereby providing a coating material.
An object of the present invention is achieved by providing a coating material for a fusible road surface marking using a phosphorescent pigment characterized by comprising a binder resin, a phosphorescent pigment, a filler, a heat stabilizer and a viscosity modifier.
According to a preferred feature of the present invention, the coating material for a fusible road surface marking using the phosphorescent pigment comprises 100 parts by weight of a binder resin, 80 to 120 parts by weight of a phosphorescent pigment, 4 to 10 parts by weight of a filler, 2 to 8 parts by weight of a heat stabilizer, And 2 to 6 parts by weight of an adjusting agent.
According to a further preferred feature of the present invention, the binder resin is made of a hydrogenated petroleum resin.
According to a further preferred feature of the present invention, the filler is made of polypropylene having a weight average molecular weight of 10,000 to 20,000.

FIG. 1 is a photograph of a coating for a fusible road surface marking using a phosphorescent pigment prepared in Example 1 of the present invention, photographed in a dark condition after being irradiated with a light source of 200 lx brightness for 20 minutes.
FIG. 2 is a graph showing the results obtained by applying a paint for a fusing surface marking using a phosphorescent pigment prepared in Example 1 of the present invention and a paint for a fusing surface marking prepared in Comparative Example 6 to a surface of a road at a thickness of 2 mm, It is a photograph taken after 1 hour passed from Shadow Shipbuilding after 12 hours of natural light in Daedong Security Co., Ltd. located in Gyeonggi Province on January 20, 2016.
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.
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.
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 .
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.
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 .
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.
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 .
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.
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.
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.
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.
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.
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.
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 .
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.
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.
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.
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.
