Description

A composition for preventing drowsiness containing a phosphorescent pigment and a road marking line construction method using the composition

The present invention relates to a road marking composition for preventing drowsiness and a road marking line construction method using the composition, and more particularly, to a road paving material such as an automobile road, a bicycle road, a pedestrian path, a walking path, etc. This is to provide a comfortable walking environment and to prevent the occurrence of safety accidents due to drowsy driving by transmitting minute vibrations to the driver as irregularities are formed.

In general, the lanes of the road are used as a guide line to guide the direction so that the vehicle on the road can move safely, and recently, to improve the visibility of the lane during rainy weather or at night, it is painted with a paint composition containing glass beads, or After painting, a paint composition containing glass beads is applied on the lane before drying, or a liquid containing glass beads is sprayed on the painted lane to adhere the glass beads to the surface of the lane to improve retroreflectivity. have.

As typical examples of such paints, room temperature-drying paint for road markings, water-soluble road marking paints, heating type paints for road markings, fusion-type paint compositions for road markings, and room temperature curing plastic paints are known, and the government stipulates KSM 6080. .

In particular, as the fusion coating composition, a composition containing petroleum resin, polyethylene wax, phthalate-based plasticizers such as di-2-ethylhexyl phthalate, calcium carbonate, glass beads, stabilizers, titanium dioxide and EVA as main components is widely used.

However, conventionally, petroleum resins were used as binder resins for fusion-bonded paints. However, the petroleum resins have a problem in that cracks occur relatively easily over time, so that the coating film formed on the surface of the road is easily damaged.

In addition, conventional road paints have a problem in that visibility is lowered at night or in rainy weather, thereby causing inconvenience to the driver or exposing the driver to dangers caused by drowsy driving. In particular, there is no problem with retroreflection of glass beads in dry conditions even at night, but there is a problem in that the visibility of lanes is rapidly reduced due to reduction of retroreflection due to total reflection of light at night due to the aquaplaning phenomenon of rainwater.

In addition, the epoxy-based polymer may further include a silicone binder having a structure of Formula 1 below in order to increase weather resistance including chemical stability.

[Formula 1]

H _a R ¹ _b SiOH

(In Formula 1, R ¹ is (C1-C20)alkyl;

In the present invention, the glass beads improve the visibility of lanes during rain or night, absorb shocks from the vehicle, and increase wear resistance and weather resistance, and may be manufactured from a material close to high-purity ceramic.

In the present invention, the glass beads may include any one or a plurality selected from titanium dioxide, calcium carbonate, silicon dioxide, cerium dioxide, zirconium oxide, aluminum oxide, germanium oxide and zinc oxide, among which silicon dioxide and other inorganic fillers It is preferable to include

In the present invention, it is preferable that the refractive index of the glass bead satisfies a specific range in order to increase the visibility of the lane due to the retroreflection. For example, as in Korean Patent Registration No. 10-1176043, a general glass bead (KS L 2521) and a high refractive bead (retroreflectivity 2.2 to 2.4) may be mixed in a specific range and used. In addition, if necessary, aluminum or the like may be deposited on the surface of the glass bead.

In addition, the aluminum oxide has an effect of improving the durability of the lane, and in the case of titanium dioxide, it is usually added as a matting agent to fibers, and in particular, it has excellent light reflectivity in the infrared region, so that it is possible to prevent the deformation of the lane due to the temperature increase of the road surface. Since zirconium oxide has the effect of improving the luminance and chromaticity of the suboptimal, it is preferable to add the above materials together with the silicon dioxide.

In the present invention, as the glass bead, not only high-brightness glass beads, but also low-brightness commercial glass beads may be used. Preferably, it is preferable to use inexpensive commercial glass beads.

The high-brightness special glass bead can be commercially purchased from 3M's glass bead, and the commercial glass bead is commercially purchased with a low-brightness used for general road pavement, more specifically, a glass bead having a luminance of 1.5 to 1.7. can be used by

Commercial glass beads can be used by purchasing No. 1, No. 2, and No. 3 from YongQing YuanGuang Glass Beads Co., Ltd. The size of the glass beads is not limited unless otherwise stated, and it is possible to use glass beads having uniform sizes and glass beads having non-uniform sizes. The size of the glass beads may be used in the range of 200 to 500 ㎛.

In addition, the glass beads may increase the roughness of the surface in order to solve the water film phenomenon by imparting super water repellency. In general, the formation of a super water-repellent film on a smooth surface has a low water repellency of about 90°, whereas the etched glass beads exhibit a super water-repellent property of 150° or more.

In the practice of the present invention, the increase in the roughness can be achieved by forming fine grooves on the surface of the glass bead, preferably in the form of a plurality of concave mirrors so that the reflection can occur in the direction in which the light source shines on the surface of the glass bead. The grooves are formed by etching. It is preferable that the concave mirror-shaped grooves formed on the surface of the glass bead have a diameter of less than 50 μm. If the size of the groove is excessively large, the structural stability of the glass bead may be lowered.

In the present invention, the etching of the glass beads may be performed by chemical treatment, preferably acid treatment. In the practice of the present invention, since the glass bead is made of silica, it is preferable to use hydrofluoric acid capable of etching the silica.

For the etching of the glass beads using hydrofluoric acid, an aqueous hydrofluoric acid solution having a concentration of 1 to 50 wt% may be used, preferably an aqueous solution having a concentration of 2 to 40 wt%, more preferably an aqueous solution having a concentration of 3 to 30 wt%, and more Preferably, an aqueous hydrofluoric acid solution having a concentration of 3 to 20 wt% may be used, and most preferably, an aqueous hydrofluoric acid solution having a concentration of 5 to 10 wt% may be used.

If the concentration of the aqueous hydrofluoric acid solution is low, it takes too long to etch the surface, which may act as a bottleneck in the manufacturing process. If the concentration of the aqueous hydrofluoric acid solution is too high, the structural stability of the glass beads may be lowered.

The etching time using the hydrofluoric acid aqueous solution may be adjusted according to the etching degree of the surface, and preferably, in the case of using a 5 wt% hydrofluoric acid aqueous solution, it is preferably performed in the range of 30 minutes to 2 hours.

The etching using the hydrofluoric acid aqueous solution may be performed by immersing the glass beads in a container containing the hydrofluoric acid aqueous solution for a predetermined time, and then separating the etched glass beads through reduced pressure filtering.

In addition, the glass beads may be coated with a photoluminescent pigment and an adhesive on the surface to increase visibility at night and in rainy weather.

In the present invention, since the photoluminescent pigment exhibits high luminance in dark situations such as at night or in rainy weather after receiving light from sunlight during the day, when applied to a lane of a road, it is possible to promote driver safety.

More preferably, barium aluminate (BaAl ₂ O ₄ ) may be included as the carrier. Even after the excitation light is cut off, the intensity of the electron lattice interaction with the rare earth metal changes in the carrier, so that blue, green, yellow, etc. luminescent colors continue for a long time. In particular, the anion (O ^{2 -} ) in barium aluminate and the rare earth metal The coordinating distance with the carrier is shorter than that of other carriers, so the intensity of the luminescence color increases.

In the present invention, as described above, the rare earth metal exhibits high-intensity light emission by causing interphase transition, and the rare earth metal may include a lanthanide group or an actinide group.

In the present invention, the rare earth metal may include dysprosium (Dy), neodymium (Nd), praseodymium (Pr), erbium (Er), europium (Eu), etc., more preferably, a mixture of europium and dysprosium. may include.

More preferably, the rare earth metal is added in the form of a mixture of europium and dysprosium. In particular, the europium and dysprosium is ttuida a uniformly white Prior to this with ultraviolet rays, there is the recipient of a light reduction, respectively Eu ²⁺ and Dy ^3+, Eu ²⁺ will activate the optical properties of the pigment, and Dy ³⁺ phosphorescent ^{A strong peak (400-600 cm -1} ) appears in the Raman spectrum by extending the phosphorescent decay time. In particular, compared to other carriers, it _{appears the highest and widest in the barium aluminate (BaAl 2} O ₄ ) matrix, thereby increasing the driver's visibility.

In the present invention, as for the rare earth metal, more precisely, the lanthanide compound, europium and dysprosium are preferably maintained in a weight ratio of 1:1 to 3, more preferably 1:2 to 2.5 by weight. In the above range, stability and light emission characteristics in the barium aluminate matrix may be greatly expressed.

In the present invention, the amount of the photoluminescent pigment is not limited, but it is preferable to add an appropriate amount in a line that does not suppress the retroreflection of the glass bead, and more specifically, 0.1 to 30 parts by weight compared to 100 parts by weight of the glass bead is added. It is preferable to do

In the present invention, the adhesive is for stably maintaining the bonding state between the glass beads and the photoluminescent pigment, and can improve weather resistance by preventing the pigment particles from detaching.

More preferably, an unsaturated polyester resin may be included as the adhesive in the present invention. As the unsaturated polyester resin is added, the change in the physical properties of the protective layer is suppressed, and the fluidity is increased, so that it is possible to prevent detachment of the pigment particles even in shrinkage and expansion due to temperature change.

In the present invention, the unsaturated polyester resin may be prepared by a conventional method in the art, for example, by reacting dipropylene glycol, diethylene glycol, tetrahydrophthalic anhydride and maleic anhydride It can be prepared by reacting 10 to 40% by weight of dipropylene glycol, 10 to 40% by weight of diethylene glycol, 10 to 40% by weight of tetrahydrophthalic anhydride, and 10 to 20% by weight of maleic anhydride. .

Examples of the ionic polymer in the present invention include polyacrylic acid, polymethyl methacrylate, polyhydroxyethyl methacrylic acid, polyvinyl alcohol, polyvinyl acetate, polyethylene oxide, polypropylene oxide, polyethylene glycol, polyacrylamide and ethyl. and cellulose, and these may be used alone or in combination of two or more.

Another example of the ionic polymer in the present invention may include polydopamine. The polydopamine is an adhesive protein produced by mussels, and has both catechol and amine, which are important chemical functional groups showing adhesive strength, and thus has excellent adhesion on all surfaces regardless of the surface properties.

In the present invention, the ionic polymer may include 1 to 10 parts by weight based on 100 parts by weight of the unsaturated polyester resin. When the ionic polymer is added in less than 1 part by weight, the adhesive force between the composition for the lane and the glass bead or the composition for the lane and the road surface may be reduced and weather resistance may be deteriorated, and when more than 10 parts by weight is added, the viscosity of the composition may decrease As it rises rapidly, workability can be very bad.
