In general, road signs such as road lanes and guide lines are necessary to promote safety and smooth communication of road traffic, and they supplement safety signs or independently convey information such as regulations or instructions to drivers, forming linear guideways on the road. It provides the visual information the driver needs to safely operate the vehicle.

In the case of domestic and foreign road signs, the dividing line for driving is indicated in white, yellow, or blue, and each color can be distinguished not only during the day but also at night or in rainy weather, so that the linear information and markings of the road described above can be provided to drivers in advance. .

However, in rainy weather, water is absorbed into the road matrix to which the road signs are fixed, making it difficult to recognize lanes properly and causing obstacles to safe driving.

Accordingly, all road signs at home and abroad are constructed with glass beads, which are retroreflectors, sprayed on top of the paint and fixed so that lanes are clearly visible even in low light levels from cars through retroreflection even in rainy weather or at night.

However, in the case of these glass beads, in the dry state, the light refraction of the glass beads is set to point towards the driver, so when a water film is formed on the surface of the glass beads in rainy weather, the refraction angle changes and the refracted light is not directed towards the driver and is dispersed into the air, reducing visibility. There was a problem of deterioration.

In addition, in the case of road signs, since road paint is simply applied and fixed on concrete or asphalt, water leaks and cracks, which are symptoms of neutralization, occur due to friction with car tires or temperature changes, and the road surface is easily contaminated. There are problems with the appearance being damaged, peeling, or being damaged.

Meanwhile, the effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The road sign visibility improver according to a preferred embodiment of the present invention is a permeable mixture of sodium silicate and aluminum silicate, an inorganic water-repellent composite of a fluorocarbon compound, silica, and ceramic, glass beads, and distilled water. , a visibility mixture to which 3-methylcyclohexane, 1-chlorooctane, 2-pentanone, and dioctyl phthalate are added, and the permeability mixture and the visibility mixture are mixed at a predetermined volume ratio.

Specifically, the road sign visibility improver of the present invention is an inorganic mixture of a permeable mixture of sodium silicate and aluminum silicate in a volume ratio of 1:2, and a fluorocarbon compound, silica, and ceramic in a volume ratio of 1:0.8:0.3. Based on 100 parts by weight of water-repellent composite, 10-30 parts by weight of glass beads, 60-100 parts by weight of distilled water, 70-90 parts by weight of 3-methylcyclohexane, 50-70 parts by weight of 1-chlorooctane, 30-50 parts by weight of 2-pentanone. It contains a visibility mixture to which 10-30 parts by weight of dioctyl phthalate is added, and the permeability mixture and the visibility mixture are mixed in a volume ratio of 1:2 to prepare a one-component type.

Sodium silicate, together with aluminum silicate, penetrates into the fine pores of a road matrix such as concrete or asphalt or road signs, and the aluminum silicate gels in the pores, thereby providing an adhesive function to reform the road matrix and prevent neutralization.

Here, when the sodium silicate is mixed with aluminum silicate to make a permeable mixture, it has a volume ratio of 1. If more than the volume ratio is added, the adhesive properties are strong, so that the aluminum silicate is deposited near the surface of the road matrix before it penetrates into the fine pores. Since hardening occurs in and permeability decreases, and if less than the above volume ratio is added, physical properties such as adhesion become insufficient, it is preferable to have a limited volume ratio as described above.

Aluminum silicate, together with sodium silicate, fills the pores when it penetrates into the fine pores of the road matrix or road signs and reacts with calcium hydroxide in the road matrix, thereby providing the function of improving the strength of the road matrix or road signs.

Here, when aluminum silicate is mixed with sodium silicate to prepare a permeable mixture, it has a volume ratio of 2. If more than the volume ratio is added, the overall viscosity increases when mixed with water or a liquid composition, and the physical properties actually deteriorate. , if less than the above volume ratio is added, the total solid content is low and the performance of penetrating into the fine pores of the road matrix or road sign is reduced, so it is preferable to have the limited volume ratio as described above.

Fluorocarbon compounds provide the function of preventing salt damage and neutralization of road matrix or road signs through physical properties such as durability, heat resistance, chemical resistance, and ultraviolet ray safety when penetrating into the fine pores of road matrix or road signs, and have a known composition. You can have

Here, when the fluorocarbon compound is mixed with silica and ceramic to produce an inorganic water-repellent composite, it has a volume ratio of 1. If more than the volume ratio is added, the durability becomes stronger when it penetrates the fine pores of the road matrix or road signs. However, the fine pore permeability of the permeable mixture decreases, and if less than the above volume ratio is added, the adhesion of the coating film to the fine pores of the road matrix or road sign decreases, and the film strength, tensile strength, and weather resistance decrease, so having a limited volume ratio as described above It is desirable.

When applied to a road matrix or road sign, silica improves the visibility of the road sign by suppressing the absorption of water around the road matrix or road sign through physical properties such as low moisture absorption, water-repellent coating properties, and durability. It may have a known configuration.

Here, when silica is mixed with fluorocarbon compounds and ceramics to produce an inorganic water-repellent composite, it has a volume ratio of 0.8. If more than the volume ratio is added, the flexibility of the entire visibility mixture becomes too large, reducing durability and constructability. If less than the above volume ratio is added, there is a problem in that the bending strength is not secured and the visibility protective layer is easily broken, so it is preferable to have a limited volume ratio as described above.

Ceramic, when applied to a road matrix or road sign, ensures that the visibility protection layer has a certain hardness through physical properties such as non-absorbency, heat resistance, chemical resistance, and waterproofness, thereby providing functions such as durability and scratch resistance of the visibility protection layer. to provide.

Here, when ceramic is mixed with a fluorocarbon compound and silica to produce an inorganic water-repellent composite, it has a volume ratio of 0.3. If more than the above volume ratio is added, the hardness of the visibility protection layer becomes too strong, causing it to be damaged by the road matrix or the road matrix during overcoating. Air pockets are generated due to the phenomenon of lifting from the road sign, and if less than the above volume ratio is added, the hardness of the visibility protection layer becomes too weak, so it is easily peeled off by impact and the diffuse reflectance is lowered, which reduces visibility. Therefore, the above-mentioned limited It is desirable to have a volume ratio.

On the other hand, the inorganic water-repellent composite is mixed with other mixtures in an amount of 100 parts by weight when manufacturing the road sign visibility improver. If it exceeds 100 parts by weight, the reaction rate becomes too fast when mixing the mixtures, and the agitation and Constructability is reduced, and if the amount is less than 100 parts by weight, the reaction speed of the mixture becomes too slow, which increases the working time and reduces the function of suppressing slippage in rainy weather. Therefore, it is better to have the limited weight part as described above. good night.

When applied to a road matrix or road sign, glass beads improve the visibility of the road sign by the amount of light from the car in rainy weather through physical properties such as retroreflectivity.

Here, 10-30 parts by weight of glass beads are mixed with 100 parts by weight of the inorganic water-repellent composite. If it exceeds 30 parts by weight, slipping occurs when in contact with car tires and it costs a lot to improve the visibility of road signs. If it is less than 10 parts by weight, there is a problem in that the retroreflectivity is not sufficiently exerted and the visibility improvement function is reduced, so it is better to have the limited weight part as described above.

Distilled water makes the permeable mixture mixed with the visibility mixture hydrophilic so that it can quickly diffuse and penetrate into the fine pores of the road matrix or road signs, thereby ensuring stable water repellency and increased strength.

Here, 60-100 parts by weight of distilled water is mixed with 100 parts by weight of the inorganic water-repellent composite. If it exceeds 100 parts by weight, the visibility mixture becomes diluted and the water repellent function cannot be secured, and if it is less than 60 parts by weight, the water repellent function is not secured. There is a problem in that the permeable mixture does not have hydrophilicity and cannot deeply penetrate into the micropores, which reduces durability and workability, so it is better to have a limited weight portion as described above.

In addition, distilled water has a temperature of 60-80℃ when mixing the visibility mixture. If it exceeds 80℃, the chain bonds of the visibility mixture with water-repellent properties are broken, so the water-repellent function and adhesive function are reduced, and when the temperature exceeds 80℃, the water-repellent function and adhesive function are reduced. If it is less than , there is a problem in that the agitation of the visible mixtures having a predetermined viscosity is reduced and they cannot penetrate into the micropores, so it is preferable to have the temperature as above.

3-Methylcyclohexane provides functions such as excellent heat resistance and elastic recovery of the coating film due to the visibility mixture when it penetrates the fine pores of the road matrix or road signs.

Here, 70-90 parts by weight of 3-methylcyclohexane is mixed with 100 parts by weight of the inorganic water-repellent composite. If it exceeds 90 parts by weight, the elasticity of the visibility protection layer decreases, causing it to be removed from the road matrix or signs during external impact. There is a problem in that it peels off easily and if the amount is less than 70 parts by weight, a lifting phenomenon occurs, so it is better to have the limited amount by weight as described above.

1-Chlorooctane provides excellent binding properties in the production of road sign visibility improvers.

Here, 50-70 parts by weight of 1-chlorooctane is mixed with 100 parts by weight of the inorganic water-repellent composite. If it exceeds 70 parts by weight, the viscosity increases and the permeability of the permeable mixture decreases, and if it is mixed with less than 50 parts by weight, the viscosity increases. In this case, there is a problem that the degree of bonding with the inner wall of the fine pores of the road matrix or road sign is reduced and it can be easily removed, so it is better to have a limited weight portion as described above.

2-Pentanone provides an antioxidant function in the production of road sign visibility improvers.

Here, 30-50 parts by weight of 2-pentanone is mixed with 100 parts by weight of the inorganic water-repellent composite. If it exceeds 50 parts by weight, the anti-oxidation function of the mixture is improved, but the fluidity increases and the stability decreases, making it difficult to overcoat. It is difficult to secure the thickness of the visibility protective layer during construction, and if it is less than 30 parts by weight, the oxidation prevention properties of the mixture are greatly reduced and the shelf life is shortened, which reduces storage and usability. Therefore, the limited weight part as above is used. It's good to have.

Dioctyl phthalate is a plasticizer that provides ductility and stability when forming a visibility protective layer.

Here, 10-30 parts by weight of dioctyl phthalate is mixed with 100 parts by weight of the inorganic water-repellent composite. If it exceeds 30 parts by weight, the ductility and stability of the mixture decreases and the adhesive function deteriorates, and 10 parts by weight is used. If it is less than that, the heat resistance is lowered and the adhesive function is actually reduced in high temperature conditions such as summer, it is difficult to maintain the physical properties due to the material separation phenomenon of the mixture, and there is a problem in that the thickness securing function is reduced during overcoating, so the above-mentioned limited It is good to have a weight part.

Meanwhile, in the permeable visibility mixture of the present invention, the permeable mixture and the visibility mixture as described above are mixed at a volume ratio of 1:2.

Here, when the volume ratio of the permeable mixture is added more than the above volume ratio or the volume ratio of the visibility mixture is added less than the above volume ratio, the sodium ions contained in the sodium silicate of the permeable mixture smoothly change into hydrophilic properties that are released by moisture or liquid of the visibility mixture. As a result, the sodium silicate reacts into a highly viscous gel-like silicic acid and quickly reacts with the calcium hydroxide in the road matrix, so the permeable mixture penetrates only near the surface of the micropores, and the water-repelling and waterproofing functions by coating the visible mixture are not sufficiently secured. There is a problem that does not exist.

In addition, when the volume ratio of the permeable mixture is added less than the above volume ratio or the volume ratio of the visibility mixture is added more than the above volume ratio, the sodium ions contained in the sodium silicate of the permeable mixture easily change into hydrophilic properties that are released by moisture or liquid of the visibility mixture. As sodium silicate reacts into a gelatinous silicate with low viscosity, it does not easily react with calcium hydroxide when applied to road matrix or road signs, so it cannot crystallize even if deeply penetrated into micropores, so only the water-repelling and waterproofing functions provided by the coating of the visibility mixture are utilized. There is a problem in that the advantages of the permeable mixture cannot be utilized.

Therefore, in the road sign visibility improvement agent of the present invention, it is preferable that the permeability mixture and the visibility mixture are mixed in a limited volume ratio of 1:2.
