ROAD MARKING COMPOSITION AND METHOD FOR COATING ROAD LINE MARKING USING THE SAME}

The present invention uses a soft resin and additives to prevent cracking, less wear, and improve the property of agglomeration of glass beads due to proper softness (flexibility) of the binder resin, thereby maintaining night brightness for a long time. The present invention relates to a melt coating composition for road marking and a construction method of a stripe road marking line using the same. The present invention is a functional stripe to improve the slip resistance and visibility of the lane so that it is easy to repair after construction in order to improve the problem of the protruding lane that was difficult to repair conventionally, and to further ensure the safety of pedestrians and drivers at night or in the rain. It is about construction method of type road marking line.

In general, on paved roads, road markings for lane guidance are provided with a certain width in order to guide the direction of the road and maintain the distance between cars. On the road, there are various types of road markings. Information on the destination regarding the speed limit and the direction of travel may be directly applied on the road surface and displayed in letters or figures, and lanes and pedestrian safety indicating the driving direction of the car. It is represented by various letters or figures such as pedestrian crossing for road signs, and the road marking paints used in this are developed and used in various kinds.

In general, the road marking composition may be roughly classified into an oily road marking paint, an aqueous road marking paint, and a fusion type road marking paint. The oily road marking paint is prepared in a liquid phase by mixing an organic solvent and a pigment with an organic synthetic resin such as acryl or alkyd, and has a high content of volatile organic compounds (VOCs), thereby becoming an environmentally harmful factor. In addition, oil-based road marking paints are thinner than fusion-type road marking paints, which have a low wear layer or a long drying time. It causes secondary pollution, and has a disadvantage of high environmental hazards such as disposal of packaging containers and residual amount.

The aqueous road marking paint is prepared in a liquid state by mixing water or pigment with an aqueous emulsion resin, and is an aqueous product, which is affected by the surrounding construction environment (temperature or humidity), and the drying time is slow, thereby limiting the construction. In addition, there are also disadvantages of environmentally harmful, such as disposal problems and scattering of the packaging container and remaining amount.

In addition, conventional conventional fusion road coating material is a mixture of pigments and glass beads, such as thermoplastic resin, is manufactured in powder form and dissolved in the primary dissolution tank when installed in the field and sprayed on the secondary construction machine The work is performed, and the secondary construction machine mainly used a manpower or a small prime mover. This method is widely used as a construction method that minimizes traffic restrictions on urban and crowded roads. However, the conventional fused paint cover paint is applied by applying general fusion paint, so the thickness is very thin and slippery, so that the friction coefficient is reduced rather than the road surface, which causes the slip of the car and impedes the safe walking of pedestrians. Is causing problems. In addition, cracks are easily generated after construction, glass beads added for visibility are easily separated, and lanes are not easily seen due to water film phenomenon during rain, and reconstruction is difficult.

In addition, the conventional fused paint coating material to increase the friction coefficient by the dot projection to suppress the slip of the vehicle, when the wheel of the vehicle passes through the protruding road marking sphere, noise and vibration is generated by the protrusion. In the case of a protruding special lane that tries to prevent the safety accident caused by drowsy driving by recognizing the direction of the vehicle, it is difficult to repair it because it is difficult to repair it. There was a problem.

The present invention is easy to handle by molding to a certain shape while maintaining the wear resistance, fast workability, environmentally-friendly advantages of the conventional fusion-type road coating paint is easy to handle, easy to apply to the road by melting To provide a composition for.

In addition, the present invention uses a flexible resin and additives to prevent cracking, less wear, and improve the property of agglomeration of glass beads due to proper ductility (flexibility) of the binder resin to maintain the brightness at night for a long time. The present invention is intended to provide a melt-type road marking composition having excellent adhesion and high anti-slip effect by being melt-bonded with instantaneous melt-installed asphalt.

In addition, since the present invention has a large number of irregularities in the driving direction of the road, it is excellent in water drainage, and the water film phenomenon is improved, and the reflex reflection surface of the vehicle light is greatly improved at the driver's viewing angle during the night driving. It is intended to provide a functional striped road marking line and its construction method that show great visual safety in comparison with the existing method at night rainy weather.

In addition, the present invention can be easily repaired when the irregularities are damaged or the brightness is lowered because the step is not generated in the stripe shape, to provide a construction method of the striped road marking line having a non-slip function by the shape of the plurality of irregularities themselves. do.

The present invention relates to a flexible molten road marking composition which can be constructed by melting, has excellent adhesiveness with asphalt, and a method of constructing a functional striped road marking line having high visibility and preventing water film phenomenon.

Specifically, the present invention

A) constructing a road marking line having a plurality of uneven portions formed along the road running direction while melting and extruding a soft melt-type road marking composition to a device having unevenness below;

B) spraying glass beads on top of the road marking line constructed; And

C) curing at room temperature;

It includes.

In the present invention, the uneven portion may be formed as one long in the driving direction of the road (see FIG. 4 (a)), or may be formed in a plurality of spaced apart at regular intervals (see FIG. 4 (b)).

In the step A), the device may be used without any limitation as long as it is a conventional device used for road marking. For example, the fusion lane coating apparatus as shown in FIG. 1 can be easily purchased and used commercially by those skilled in the art and is used without limitation in the construction of the present invention. However, as shown in FIG. 1, in the conventional apparatus, the plate 11 provided in the lane paint part 10 has a groove having a date corresponding to the thickness to be painted, and when using the road marker line having a flat surface This is constructed. As the road sign line constructed in this way becomes flat, water film is formed in rainy weather, visibility is reduced, and the surface is slippery, which is dangerous when walking.

Therefore, in order to solve the present invention, as shown in FIG. 2, the present invention provides a flexible composition which is melt-extruded and laminated on the road by forming the unevenness 22 under the plate 21 provided in the lane paint portion 20. It acts like a plow, making it possible to form long grooves in the driving direction.

At this time, grooves (corrugated, 32) is formed in the place where the unevenness (22) of the lane paint portion is pushed, and is applied in the form of unevenness, and the composition to be melt-extruded has a ductility so that the space between the grooves is crushed to form a round road marking line (30). ) Is constructed. If the road marking composition is hard and durable and hard resin is used, the grooves may be sharply formed between grooves and may be severely broken by friction or wear loss. However, the present invention uses a soft composition. Could solve.

The road marking line 30 constructed by the above construction method has a plurality of concave long stripe-shaped grooves 32 formed in a concave length as shown in FIGS. 3 and 4 (a), so that it is easy to drain during rain.

In addition, the plate 21 having the unevenness 22 may be used only in part, so that the unevenness portion may be spaced apart at regular intervals in the driving direction as shown in FIG. When applied in this way, braking and anti-drowsy effects can also be achieved.

As shown in FIGS. 5 and 6, the road marking line according to the present invention has improved visibility by the glass beads 33 protruding at the front side at night, as well as the grooves 32 and the protrusions 31 of the uneven parts even in rainy weather. Retroreflective is made by the glass beads 33 formed on the surface between) to ensure the visibility.

In addition, since the plurality of grooves 32 are formed in the driving direction during driving, the area visible in the viewing direction increases as shown in FIG. 6, so that visibility is greatly improved. At this time, the width and spacing of the groove is not limited, but when formed in 1 ~ 10mm is more excellent visibility.

Since the composition used for the road marking line is soft, it is preferable to further have a step of spreading the glass beads before the road marking line is completely cured because the glass beads in the composition are going to sink down by the property thereof.

The road marking line according to the present invention can be used in various fields such as lanes, crosswalks, and other road markings.

Next, the soft melt-type road marking composition used in the present invention will be described in detail. The binder resin 40 to 60% by weight, the coloring pigment 5 to 30% by weight, glass beads 1 to 30% by weight, wax (wax) It contains 1 to 20% by weight of alkanes having 40 to 115 carbon atoms.

After the binder resin is applied to the road and cured, the binder resin is closely adhered to the road surface, and the pigment and glass beads remain on the road while remaining for a long time so as to function as road signs. This is excellent.

As the binder resin, any one or two or more blends selected from polyamide resin, ethylene vinyl acetate resin, polyethylene resin, thermoplastic elastomer, and polyester resin can be used.

The binder resin is used in the range of 40 to 60% by weight, and when used in less than 40% by weight, there may be a problem in that the durability of the road sign is reduced due to the decrease in the thickness of the coating film constituting the road sign and the deterioration of physical properties. If it exceeds 60% by weight there may be a problem that the distribution of the glass beads in the coating is non-uniform.

In the present invention, the coloring pigment has a function of imparting a color, the pigment is to be expressed in a desired color, and can be used by selecting a suitable pigment according to a predetermined color, such pigments are commercially available if those Known enough to be purchased and used, it can be used without limitation. Pigment may be used in the range of 5 to 30% by weight of the total weight of the composition, when used in less than 5% by weight may not have enough color to give a problem that can not function as a road sign, 30 weight In case of exceeding the%, there may be a problem of inhibiting the physical properties of the composition by reducing the essential content of the other components rather than a special improvement in color.

The glass bead receives a light of the headlight of a car at a road sign and reflects it at night, so that the glass bead can be easily read and recognized by the human eye such as a driver or a pedestrian. The glass beads may be used in the range of 1 to 30% by weight based on the total weight of the composition, and when used in less than 1% by weight may have a problem that the night marker function as described above is lowered, 30% by weight If exceeded, there may be a problem of inhibiting the physical properties of the composition by reducing the essential content of the other components rather than without a special improvement of the identification function. In addition, in the construction method there is a step of further spraying the glass beads before the cured completely after the formation of the road marking line using the composition, it is not necessary to use more than that content. The size of the glass beads is not limited, but it is preferable to use an average particle diameter of 0.1 to 2.5mm because of excellent braking force and visibility.

In the present invention, the alkane compound having 40 to 115 carbon atoms on the wax is a non-petroleum polymer material, which is extracted from coal and is a wax-like material manufactured by Fischer Tropsch synthesis. When the composition is melted, the softening point is lowered to facilitate the melting, the flow property of the paint is improved, and the coating is well performed, thereby forming a coating film having a uniform thickness on the road surface. Even after contamination of the coating film after drying, it functions to be easily washed away by rain water. Examples of such alkaline compounds include sasobit of sasol. It is preferable to use in the range of 1 to 20% by weight, and when used in less than 1% by weight, there may be a problem of lowering the meltability and contamination resistance, and when it exceeds 20% by weight, the cracking phenomenon due to the decrease in strength of the coating film may occur. There may be a problem such as occurring.

In addition, the present invention has a titanium oxide (TiO ₂ ), bottom ash (Bottom ash, lime ash flooring) having a particle size of 100 ~ 300 mesh with respect to 100 parts by weight of the composition for road marking to improve the braking properties and anti-slip effect One or more porous inorganic or ceramic aggregates selected from fly ash (fly ash, fly ash fly ash), pearlite, and zeolite may be further included in an amount of 1 to 50 parts by weight. If it exceeds 50 parts by weight, the ductility of the composition is reduced, which is undesirable.

The ceramic aggregate is then firing the inorganic material in 900 ~ 1700 ℃ pulverized, as a material that maximized the porosity and improve the strength, the titanium oxide (TiO _2), bottom ash (Bottom ash, stone takhoe flooring), fly It is also possible to manufacture using ash (Fly ash, fly ash fly ash), pearlite, zeolite and the like.

In addition, a plasticizer may be additionally included to prevent breakage of the coating and to give flexibility, and when forming the composition according to the present invention, the softening point is lowered to improve moldability, thereby forming a beautiful appearance. Function to make it. The plasticizer may be used as a petroleum compound of DOP, but there are environmental problems, vegetable oil may be used, but there are problems in storage and handling, the coating composition according to the present invention to solve the two problems Mineral oil is used, and the mineral oil may be used so that it is well known to those skilled in the art to purchase and use commercially supplied by leading domestic and foreign manufacturers.

A photograph showing an example of the striped lane according to the present invention is shown in FIG. 7.

The striped functional road marker line according to the present invention can be applied to various fields such as lanes, pedestrian crossings, road markings, and also provides visibility and visibility to drivers and pedestrians as grooves are formed along the driving direction of the road. This effect is greatly improved.

In addition, since rainwater flows along the grooves during rainy weather, there are few water traps, and since the protrusions do not form a water film, water film phenomenon may occur due to conventional water pools, thereby improving visibility and slippery problems.

In addition, the present invention has the advantage that it can be repaired because it can exhibit the effect even if the overlay because the stripe type in the case of the conventional protruding lanes can not be repaired by the step. In addition, the renovation is easy to construct in urban centers and already open traffic roads, it is environmentally friendly.
