DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road marking buried on a road or a parking lot, and more particularly, to improve the safety of traffic at night due to the fact that the road marking emits light with high brightness in the dark. Also, the present invention relates to a phosphorescent road marking having a security effect.

[0002]

2. Description of the Related Art On roads, white road markings (white lines) are provided on a center portion and side surfaces. General road markings are formed by mixing a white paint with a hardener or adhesive, etc., and are appropriately applied on the road surface to clearly indicate the center of the road and the left and right side positions of the road to drivers and pedestrians. are doing.

In a parking lot, road markings indicating positions (frames) at which vehicles are parked are provided at regular intervals, and arrow-shaped road markings are provided to guide vehicles entering and exiting the vehicle.
Car parking is managed smoothly.

[0004]

However, since road markings on roads are mainly made of white paint, it is difficult to clearly confirm the position of the road markings at night or in the dark. And there was a drawback that accidents occurred frequently at night. In addition, it is difficult to confirm the traveling direction and the parking area at night on road markings provided in a parking lot, which may cause a contact accident or the like.

Further, in the conventional road marking, since white paint is applied directly on the road surface, after a long period of time, the tire gradually wears due to friction of vehicle tires and the like, and it is necessary to repaint regularly.

In view of the above, the present invention clearly indicates the traveling direction of a vehicle at night by making a road sign provided on a road or a parking lot emit natural light with high luminance for a long time in the dark. Another object of the present invention is to provide a phosphorescent road marking that can obtain excellent safety and guidance effects and also has a security effect.

[0007]

In order to solve the above-mentioned problems, a phosphorescent road marking according to the present invention is a road marking embedded in a road or a parking lot, and the road marking is a surface of a marking substrate. And a mixture of a luminous agent and a ceramic powder fired in the groove.

Further, a plurality of the concave grooves are provided on the surface of the sign substrate in the longitudinal direction.

[0009] The mixture comprises a phosphorescent agent, a ceramic powder, a glaze, and a curing agent.

Further, titanium oxide was calcined on the surface of the mixture.

By arranging and embedding a plurality of sign boards, in which the mixture is baked in the groove, in a road or a parking lot, the mixture irradiates sunlight or light emitted from a lighting device or the like with the mixture during the day. In the night, the sign substrate can emit light naturally at high luminance for a long time in the dark. Therefore, the traveling direction of the vehicle at night can be clearly displayed, and excellent safety and guidance effects can be exhibited.

Further, by baking titanium oxide on the surface of the mixture, it is possible to reduce the adhesion of dust and dust in the concave groove and to purify the air around the installed sign substrate.

Since the mixture and the titanium oxide are fired in the groove, the shoe sole and the tire of the vehicle do not come into direct contact with each other, so that the occurrence of wear and peeling can be eliminated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a phosphorescent road marking according to the present invention will be described with reference to the drawings. 1 is an overall perspective view showing a phosphorescent road marking, FIG. 2 is an enlarged sectional view of the phosphorescent road marking,
FIG. 3 is an enlarged sectional view of another embodiment of the light storing road marking, FIG. 4 shows a state where the light storing road marking is installed in a parking lot, and FIG. 5 shows a state where the light storing road marking is installed on a road.

The phosphorescent road marking 1 of the present invention is buried on a road or a parking lot, and indicates a traveling method of a vehicle, a side position of a road, and the like.

The sign board 2 of the phosphorescent road sign 1 is made of rectangular concrete having excellent durability and strength. On the surface of the sign board 2, a concave groove 3 having a V-shaped cross section is formed.
Is given.

A plurality of the grooves 3 are provided at equal intervals on the surface of the sign substrate 2 in the longitudinal direction.
A mixture 4 composed of a phosphorescent agent and a ceramic powder is fired.

The luminous agent is formed by mixing a plurality of well-known metal compounds and rare earths and mixing a general-purpose coloring agent, and luminesces light radiated from sunlight or lighting equipment.
A fluorescent color can be spontaneously emitted in the dark.

The ceramic powder is obtained by developing a conventional method for producing ceramics, and processing a non-metallic inorganic material obtained through processes such as molding and firing into a powder. In addition, since the ceramic powder emits far-infrared rays of 4 to 400 microns, which are almost the same as the frequency of the molecules constituting the substance,
It is well known that when irradiated with a temperature higher than room temperature, such as sunlight, the molecules are deeply penetrated in the substance and resonate and activate.

For this reason, when the mixture 4 composed of the luminous agent and the ceramic powder is baked in the concave groove 3 provided on the surface of the sign substrate 2 to irradiate sunlight or light from a lighting fixture or the like. In addition, the far-infrared action of the ceramics activates the molecular activity of the luminous agent to improve the luminous intensity, and allows the mixture 4 to emit light with high luminance for a long time.

The mixture 4 is formed by appropriately mixing a glaze and a curing agent based on a phosphorescent agent and a ceramic powder. The glaze is used when a surface of a ceramic is polished, and a white glaze is particularly preferable. The curing agent is for curing the phosphorescent agent, the ceramic powder and the glaze, and calcium chloride or the like is used.

It is to be noted that a white paint is previously applied to the inside of the concave groove 3 and the mixture 4 is applied to the upper surface of the white paint.
Can be further improved.

As another preferred example, as shown in FIG. 3, it is preferable to bake titanium oxide 5 on the surface of the mixture 4. The titanium oxide 5 is composed of an amorphous titanic acid solution (PTA sol) and a peroxo-modified anatase (P
(A sol), and the photocatalytic function of the titanium oxide 5 can reduce dirt such as dust and dirt adhering in the concave groove 3. In addition, the air around the sign substrate 2 can be cleaned to prevent the occurrence of mold and the propagation of various bacteria.

Further, it is needless to say that the concave groove 3 is not limited to the substantially V shape shown in the figure, but may be formed in a concave shape or a semicircular shape. By baking the mixture 4 or titanium oxide 5 in the concave groove 3 having the above-mentioned shape, the shoe sole of a pedestrian or the tire of a vehicle is not directly in contact with the mixture 4 or titanium oxide 5 and is worn or peeled. Can be eliminated.

Next, details of the method of using the phosphorescent road marking of the present invention will be described with reference to FIG. 4 or FIG.

FIG. 4 shows a state in which a plurality of phosphorescent road surface markings 1 are arranged and buried in a frame 7 for parking a vehicle in a parking lot 6. In this case, since the luminous road marking 1 emits the fluorescent color naturally in the dark for a long time at night, the vehicle can be easily parked in the frame. Further, in an unmanned parking lot, the periphery of the phosphorescent road marking 1 is illuminated brightly, so that the effect of preventing the vehicle from being stolen can be exerted. In addition, by embedding the phosphorescent road surface marking 1 at a location where the vehicle is guided in the parking lot, the vehicle can be smoothly entered and exited even at night.

FIG. 5 shows a state in which a plurality of luminous road markings 1 are buried in the center 9 and the side surface 10 of the road 8. In this case, the driver can easily confirm the width of the road and the traveling method by the phosphorescent road surface sign 1 emitting the fluorescent color naturally in the dark for a long time at night. In addition, since the mixture 4 and the titanium oxide 5 are baked in the concave groove 3, the shoe sole of a pedestrian or the tire of a vehicle does not come into direct contact, and the occurrence of abrasion and peeling can be solved.

[0028]

As described above, the phosphorescent road marking of the present invention has the following effects as described above.

By arranging and embedding a plurality of sign boards, in which the mixture is baked in the grooves, in a road or a parking lot, the light emitted from sunlight or lighting equipment is stored by the mixture during the daytime. In the meantime, the sign substrate can emit natural light with high luminance for a long time at night. Therefore, the traveling direction of the vehicle at night can be clearly displayed, and excellent safety and guidance effects can be exhibited.

Further, by baking titanium oxide on the surface of the mixture, it is possible to reduce the adhesion of dust and dust in the concave groove and to purify the air around the embedded sign substrate.

Further, since the mixture and the titanium oxide are baked in the grooves, the soles of the shoes and the tires of the vehicle are not directly in contact with each other. be able to.
