The second hopper 31 has a second paint therein and a second outlet 31a at the bottom thereof. And a first paint spraying member (32) for spraying a second paint supplied through the second hopper (31) onto a road surface A paint tank 41 provided on both sides of the diaphragm 30 and the second hopper 31 and having a third paint stored therein and a third discharge port 41a formed at a lower portion thereof and a paint tank 41 And a second paint spraying member (42) communicating with the third discharge port (41a) of the second paint spraying member (41) and spraying a third paint supplied through the paint tank (41) .

At this time, the third paint sprayed from the second paint sprayer 42 may be sprayed on at least a part of both sides of the second paint sprayed from the second paint sprayer 42.

That is, the protruding lane 60 can be formed primarily by the first paint discharged from the discharge station 20, and the second paint sprayed from the main discharge ceiling 30 can be used as the second paint The display lane 70 may be formed and the identification lane 80 may be formed by the third paint sprayed from the auxiliary spraying liquor 40. [

Particularly, the first paint discharged from the discharge station 20 may be formed as a lane having a predetermined thickness protruding from the ground by 10 mm to 30 mm. For this purpose, the first paint discharged from the discharge station 20 The paint may be composed of at least a non-visible paint having a higher viscosity than the second paint and the third paint.

The on-off valve 20 may be provided with an on-off valve (not shown) for supplying the first paint uniformly by a predetermined amount, and the on- Can be supplied.

The frame 10 may be provided with one or a plurality of fastening portions (not shown) so that a separate driving portion 90 for driving the lane setting apparatus of the present invention can be coupled.

The driving equipment includes a painting tank, a heating burner, a fuel tank, And a power source necessary for driving the soil discharge studying unit 20, the main spraying study unit 30, and the auxiliary spraying study unit 40.

The frame 10 may be provided with a fluid supply source 11 capable of supplying a fluid as a power source to the main spraying station 30 and the auxiliary spraying station 40, And may be configured to supply gas as a heating fuel to the main spraying study unit 30 and the auxiliary spraying study unit 40.

The third paint stored in the paint tank 41 may have a color different from that of the second paint stored in the second hopper 31.

This is because the third paint stored in the paint tank 41 is sprayed on both sides of the second paint stored in the second hopper 31 to improve the discriminating power of the second paint, The second paint and the third paint may be configured such that, for example, when the second paint is composed of white, the third paint is composed of black.

The second paint spraying member 42 is disposed behind at least the first paint spraying member 32 so that a third paint sprayed from the second paint spraying member 42 is sprayed to the first paint spraying member 32, And may be configured to be laminated on a part of both sides of the second paint sprayed from the jetting member (32).

Further, the protruding type spray lane construction apparatus of the present invention may include a control unit for controlling the opening / closing degree of the opening / closing valve, and the control unit is configured to adjust the opening / closing degree of the opening / closing valve, A large amount of the first paint can be controlled to be discharged.

In other words, the control unit controls the discharge amount of the first paint to be small at first and gradually increases, thereby preventing the irregularities formed by the first paint from being damaged as the vehicle changes lanes.

The control unit may be configured to control a discharge interval of the first paint discharged from the discharge unit 20 and a discharge interval of the second paint sprayed from the main discharge port 30.

The controller controls the discharge interval (a) to be formed between the first paint discharged from the discharge port (20) and another first paint adjacent to the first discharge port (20) (2) is formed so as to have an interval larger than at least the ejection interval (a) between the plurality of ejection intervals (a) so that the ejection interval (c) b) may be formed.

At this time, the discharge interval (a) may be formed 2 to 4 times between the stop interval (b) and another adjacent stop interval (b). More specifically, the discharge interval (B) may be formed after the first paint is discharged three to five times at the discharge interval (a) and the first paint is discharged three to five times at the discharge interval (a) And most preferably, the first paint is discharged four times while the second paint is sprayed once.

When the first paint is discharged twice or less while the second paint is sprayed one time, the amount of reflected light of the vehicle is insignificant because the number of the projected lanes 50 is too small, If the first paint is discharged more than six times during the injection, the number of the projecting lanes 50 becomes too large, and the amount of light reflected by the vehicle becomes large, which may interfere with the driver's view.

The control unit may be configured to calculate the moving distance according to the moving speed and the moving time of the driving unit 90 to adjust the discharging interval a, the stopping interval b, and the jetting interval c.

In other words, the control unit calculates the distance traveled by the lane setting apparatus in accordance with the speed at which the lane marking apparatus of the present invention is moved and the time at which the lane marking apparatus moves, and determines the discharge interval (a) at which the first paint is discharged, (B) in which the second paint is sprayed and the spray interval (c) in which the second paint is sprayed.

6 is a view showing a press section of a projecting type spray lane construction apparatus according to the present invention.

6, a protruding type spray lane construction apparatus according to the present invention is provided with a second cylinder (not shown) provided in the frame 10 and provided between the soil discharge station 20 and the main injection station 30, (50) including a second cylinder rod (52) which is slid in the vertical direction by the first cylinder (51) and the second cylinder (51), and the stamp (52a) And the press unit 50 may be provided between the soil discharge station 20 and the main spraying station 30. [

This is because the press section 50 presses the first paint discharged by the discharge station 20 using the stamp 52a so that the first paint is formed in a shape corresponding to the stamp 52a So that the concavities and convexities are formed in plural.

That is, when the shape of the plurality of protrusions formed on the stamp 52a is formed in a direction orthogonal to the vehicle traveling along the lane, light emitted from the headlight or the streetlight of the vehicle is formed by the press portion 50 The lane can be more easily distinguished by the driver and the pedestrian by being reflected by the uneven portion of the first paint.

At this time, not only the plurality of projections formed on the stamp 52a are formed only in a direction orthogonal to the vehicle, but also the light emitted from the headlamp or the streetlight of the vehicle is reflected according to the embodiment so that the driver and the pedestrian can easily It can be configured to be deformable as long as the shape can be identified.

The pressing part 50 is provided between the soil discharging part 20 and the main spraying part 30 because the second coating material is sprayed onto the first coating material discharged from the soil discharging part 20, And the stamp 52a of the press part 50 presses the first paint before the second paint is sprayed onto the first paint according to various embodiments, If the press portion 50 can press the first paint, it is possible to deform it as much as possible.

7A and 7B are views showing a paint supply member and a bridge of a protruding spray lane construction apparatus according to the present invention.

7A and 7B, the paint supply member 23 of the present invention includes a paint discharge pipe 23a which is formed in a vertical direction and communicates with the paint supply pipe 22, an upper portion of the paint discharge pipe 23a And a first cylinder rod 23c which is moved in the vertical direction by the first cylinder 23b and applies pressure to the interior of the paint discharge pipe 23a.

At this time, one or a plurality of bridges 23d are formed at the end of the paint discharge pipe 23a so that the first paint discharged through the paint discharge pipe 23a can be divided and discharged by the bridge 23d have.

This is so that the first paint discharged through the paint discharge pipe 23a is divided and discharged by the bridge 23d. When the first coating material is divided and discharged by the bridge 23d, the first coating materials of the plurality of the divided materials come into contact with the ground surface and spread to the periphery and are rejoined to each other. The amount of one paint is smaller than the amount of the first paint at the center of each of the plurality of first paints, so that the cross-sectional shape of the first paint becomes a curved line.

That is, when the first paint is divided and discharged and the cross-sectional shape of the first paint becomes a curved line, light emitted from a headlight or a street lamp of a vehicle is reflected by the curve of the first paint so that the driver and the pedestrian So that it can be more easily identified.

In this case, the first coating material may be composed of a composition that can be gradually rejoined while being in contact with the ground in a state of being separated by the bridge (23d), and the composition of the first coating material may be modified according to various embodiments .

In addition, the one or more bridges 23d are formed only in a direction orthogonal to the vehicle.

When the acrylic polymer is contained in an amount of less than 20% by weight, adhesion with the road surface is deteriorated and durability can not be enhanced. When the acrylic polymer is added in an amount exceeding 50% by weight The silking phenomenon occurs when the composition is applied in a thin thread shape when the composition is applied, resulting in poor appearance of the lane.

The urethane-based polymer means a polymer in which a unit containing a urethane bond (-NH-CO-) is repeatedly polymerized, and can be used without limitation as long as it is ordinarily used in the field of coating technology. The urethane polymer preferably has a weight average molecular weight of 5,000 to 500,000 g / mol.

The urethane polymer may be synthesized from a hard segment using glycol and amines, a soft segment using polymeric glycol, and a polyisocyanate as main raw materials. The urethane polymer may be synthesized by any one of a one-shot method of reacting a polyurethane glycol and a chain extender with a polyisocyanate in one shot, and a prepolymer method in which a polyisocyanate is excessively reacted and a prepolymer is further chain extended ≪ / RTI > The polyurethane emulsion is excellent in tensile strength, excellent in chemical resistance and abrasion resistance, and can be used in a wide variety of applications such as elastomers, flexible foams, rigistic foams, plastics, paints, adhesives, It is widely used in almost every field of materials.

The urethane polymer preferably comprises 10 to 40% by weight of the total protruding composition and 100% by weight of the surface part composition, respectively. If less than 10% by weight is added, the effect of improving tensile strength, chemical resistance, abrasion resistance and the like is insufficient, and when it is added in an amount exceeding 40% by weight, ductility tends to be strong and deformation of the projections due to load tends to occur.

The epoxy compound can be used without limitation as long as it is a monomer having an epoxy group. Specifically, the epoxy compound may be an epoxy compound containing at least one epoxidized aliphatic ring group, an epoxy compound containing at least one glycidyl ether group, or a compound having at least two epoxy groups and at least one aromatic ring in the molecule. Specific examples of the epoxy include 3,4-epoxycyclohexylmethyl, 3,4-epoxycyclohexanecarboxylate, bis (3,4-epoxycyclohexylmethyl) adipate dicyclopentadiene oxide, limonene dioxide and Cyclohexanedimethanol diglycidyl ether, novolak epoxy, bisphenol A-based epoxy, bisphenol F-based epoxy, brominated bisphenol-based epoxy, 1,6-hexanediol diglycidyl ether, (C12-C14), 2-ethylhexyl glycidyl ether, phenylglycidyl ether, o-cresyl ether, trimethylolpropane triglycidyl ether, n-butyl glycidyl ether, aliphatic glycidyl ether One or more selected from Cresyl glycidyl ether, nonylphenyl glycidyl ether, 1,4-butane diol diglycidyl ether, propylene glycol diglycidyl ether, and ethylene glycol diglycidyl ether, and the like Can include The.

In addition, the epoxy compound further includes a multi-reactive epoxy resin in order to increase the interaction with functional groups such as amine, hydroxy and carboxy contained in the acrylic polymer, the urethane polymer, etc. to greatly improve the instantaneous adhesive strength and the holding strength of the coating .

The multi-reactive epoxy resin has an effect of increasing the whiteness of the coating film, lowering the yellowing resistance and eliminating the gel phenomenon of the composition, and may include epoxide oligomers of multi-cyclic conjugated dienes.

Examples of the polycyclic conjugated dienes include tetrahydroindene, methyltetrahydroindene, dicyclopentadiene, bicyclo (2,2,1) -hepta 2,5-diene, bicyclo (2,2,1) -hepta-2,5-diene, alkylnorbornenes, alkylidene norbornenes, cycloalkenylnorbornenes, norbornenes, cycloalkenylidene norbornenes, and the like, but are not limited thereto.

The multi-reactive epoxy resin may contain 0.1 to 10% by weight based on 100% by weight of the epoxy compound. If it is added in an amount of less than 0.1% by weight, the effect of increasing the holding strength of the composition is insufficient, and if it is added in an amount of more than 10% by weight, workability of the composition may be significantly decreased due to excessive reaction.

The above-mentioned methacrylic acid is added in order to improve the bonding strength, durability and weatherability of the coating after mixing with the acrylic polymer. In order to improve adhesion strength, bonding strength and impact strength with other additives to be described later, And 0.1 to 20% by weight relative to 100% by weight of the composition.

The inorganic filler may include any one or more selected from titanium dioxide, calcium carbonate, silicon dioxide, cerium dioxide, zirconium oxide, aluminum oxide, germanium oxide and zinc oxide, .

The silicon dioxide is an additive which is also referred to as glass beads and it is preferable that the refractive index satisfies a specific range in order to enhance the visibility of the lane due to the recursive reflection. For example, common glass beads (KS L 2521) and high-refractive-index beads (retroreflectivity 2.2 to 2.4) may be mixed in a specific range as in Korean Patent No. 10-1176043. It is also possible to deposit aluminum or the like on the surface of the glass beads as needed.

Aluminum oxide among the above inorganic fillers has an effect of improving the durability of the lane. In the case of titanium dioxide, it is added to the ordinary fiber as a quencher. In particular, since the light reflectivity in the infrared region is excellent, have. Also, since zirconium oxide has the effect of improving lane luminance and chromaticity, it is preferable to add the above materials together with the above silicon dioxide.

The inorganic filler is preferably contained in an amount of 0.1 to 20% by weight based on 100% by weight of the surface part composition. If less than 0.1% by weight is added, the effect of increasing the visibility and weatherability of the lane is insufficient, and if it is added in an amount exceeding 20% by weight, the workability may be significantly lowered.

The pigment is used for expressing the hue of the surface part composition and basically has a white color but may have a yellow or blue color depending on the application. Since the pigment according to the present invention basically has a white color due to the addition of silicon dioxide or the like contained in the inorganic filler, it is possible to impart color to the composition by further adding a pigment having a desired color.

The pigment may be used without limitation in the range to achieve the above object, and if necessary, an organic pigment that reflects infrared rays may be used.

More specifically, the pigment may include organic pigments, inorganic pigments, extender pigments, and the like. Since the organic pigments and the inorganic pigments are continuously exposed to light and heat due to the characteristics of roads and friction with the tire is continuously applied, durability, especially light resistance, acid resistance and frictional resistance, .

The extender pigment may be selected from a mixture of inorganic fillers and extender pigments such as calcium carbonate, talc, silica, mica, kaolin and the like. The extender pigments are used for controlling the physical properties such as fluidity and viscosity of the paint, , Gloss control and so on.

The amount of the pigment is not limited, but is preferably 0.1 to 20% by weight based on 100% by weight of the entire surface part composition, from the viewpoints of color development and workability.

The adhesion-promoting agent is characterized in that at least one of the adhesion-promoting agents is selected as an additive which plays a role in increasing the adhesion with the substrate.

The adhesion promoter enhances the adhesion between the substrate and the coating film during the drying of the coating film, and the adhesion promoter enhances adhesion between the substrate and the coating film. The adhesion promoter enhances adhesion between the substrate and the coating film, Methoxyethoxysilane, and the like, and it is more preferable to use an acrylate-based polyester oligomer.

The antioxidant and ultraviolet light stabilizer may be one or more selected from the group consisting of phenol, thio, phosphorus, and amine as the antioxidant and ultraviolet absorber and blocking agent. Examples of the ultraviolet light stabilizer include benzotriazoles, benzophenones , Triazine type, organo-nickel type, ultraviolet ray blocking agent and ultraviolet ray absorbing agent.

Antioxidants and ultraviolet stabilizers prevent the color of the coating film from drying due to contact with ultraviolet rays and air after drying or after drying. Redox reaction occurs when the polymer is exposed to ultraviolet rays and air. oxidant) and ultraviolet stabilizer are most excellent in controlling long-term color fading and yellowing, and thus good physical properties can be obtained in terms of weather resistance of ultraviolet rays and air. As the antioxidant, antioxidants such as phenol, thio, phosphorus, and amine are used, and one or more antioxidants are selected.

The ultraviolet light stabilizer is divided into ultraviolet light absorbers and ultraviolet light absorbers depending on their function, and may be selected from benzotriazoles, benzophenones, triazines, organo-nickel compounds, ultraviolet absorbers and ultraviolet absorbers.

The amount of the additive to be added to the composition can be freely controlled within the range not impairing the object of the present invention. In addition to the above-mentioned additives, various additives may be further added considering the physical properties of the composition.

The projecting lane composition according to the present invention may further include carbon fibers to improve the mechanical strength of the projections.

The carbon fibers are not particularly limited, but PAN-based carbon fibers, pitch-based carbon fibers, cellulose-based carbon fibers, vapor-grown carbon fibers, and graphitized fibers thereof can be used. Here, the PAN-based carbon fiber is carbon fiber comprising polyacrylonitrile fiber as a raw material. Pitch-based carbon fibers are carbon fibers made of petroleum tar or petroleum pitch. The cellulose-based carbon fiber is carbon fiber made of viscose rayon, cellulose acetate or the like. The vapor grown carbon fiber is a carbon fiber made of hydrocarbons or the like as a raw material. Of these, PAN-based carbon fibers are preferable in that they are excellent in balance between strength and elastic modulus. Further, metal-coated carbon fibers obtained by coating a metal such as nickel or copper on the carbon fibers may be used.

The carbon fibers preferably have an average length in a specific range to improve tensile strength and elongation. More specifically, the average length is preferably 100 占 퐉 or less, more preferably 10 to 100 占 퐉, and most preferably 20 to 40 占 퐉 in terms of improvement in tensile strength and elongation.

The carbon fiber is preferably added in an amount of 0.1 to 5 wt% in 100 wt% of the protruding composition. If the addition amount is less than 0.1% by weight, the effect of improving the mechanical properties of the projections is insufficient. If the addition amount exceeds 5% by weight, the viscosity may increase sharply and workability may be deteriorated.

Also, the projecting lane composition according to the present invention may further include perhydro polysilazane and silica beads in the surface part composition in order to keep the shear strength constant and to prevent separation of the pavement layer, plastic deformation, fatigue cracking, It is possible.

The perhydropolysilazane contains a nitrogen atom in its main chain and can react with water and functional groups in the composition to form a network. Accordingly, since the perhydro polysilazane rapidly undergoes curing and crosslinking, there is no need to satisfy the additional crosslinking agent or crosslinking condition, and the crosslinking occurs regardless of the temperature. Therefore, the adhesion property to the interface with the road and the protrusion is improved, And the resistance against vertical tensile stress is increased, so that breakage of the lane can be prevented.

In addition, the perhydro-polysilazane forms a silicon dioxide network structure when cured with water. It increases the weatherability such as a kind of silica beads such as antifouling and a method, induces total internal reflection upon exposure to the surface, .

The silica beads improve the non-slip property to keep the shear strength and scratch resistance constant and to prevent breakage of the packing layer. In addition, when the silica beads are mixed with perhydro polysilazane, the maximum bonding strength of the composition is increased, can do.

The silica beads are preferably modified to improve the bonding strength with other compositions. For example, when a film is formed on the surface of a silica bead with a crosslinking agent and a silane coupling agent, the film acts as a velcro capable of adsorbing other components to increase the mechanical strength of the composition, Can be increased.

Examples of the crosslinking agent include polyfunctional crosslinking agents such as acrylic acid or methacrylic acid esters of diols such as triols such as butanediol diacrylate and glycerol, acrylic acid or methacrylic acid esters of tetrol such as pentaerythritol But are not limited to, those selected from one or more. Other useful crosslinking agents include polyvinyl crosslinking agents such as substituted and unsubstituted divinylbenzene; And di-functional urethane acrylates, and mixtures thereof.

The crosslinking agents are incorporated at concentrations compatible with their known uses and retention of adhesion properties. Factors to be considered include, but are not limited to, the molecular weight of the crosslinking agent, the degree of the polyfunctional group, and the concentration of the crosslinking agent. Cross-linking reactions can occur through exposure to an appropriate heat source.

The silane coupling agent may be mainly an alkoxysilane compound. Examples of the siloxane coupling agent include tridecyltrimethoxysilane, tridecylmethyldimethoxysilane, undecyltrimethoxysilane, diundecyldimethoxysilane, octadecyldimethyl Alkylalkoxysilane compounds such as methoxysilane, octadecyldimethylethoxysilane, decyldimethoxysilane, hexyltrimethoxysilane, and hexylmethyldimethoxysilane; Octenyltrimethoxysilane, hexenylmethyldimethoxysilane, etc .; Aromatic alkoxysilanes such as phenyltriethoxysilane, benzyltriethoxysilane, phenylethyltriethoxysilane and quaternary butylpentyldimethylmethoxysilane; And alkoxysilane systems containing cyclic hydrocarbon functional groups such as bicycloheptenyltriethoxysilane, acyclic heptanylmethylimethoxysilane, and cyclohexyldimethylethoxysilane; Epoxy groups such as 3-glycidoxypropyltrimethoxysilane, 3-glycidoxypropyltriethoxysilane, 3-glycidoxypropylmethyldiethoxysilane and 2- (3,4-epoxycyclohexyl) ethyltrimethoxysilane. Containing silane coupling agent, 3-aminopropyltrimethoxysilane, N-2- (aminoethyl) -3-aminopropylmethyldimethoxysilane, 3-triethoxysilyl-N- (1.3-dimethylbutylidene) propyl (Meth) acrylic group-containing silane coupling agents such as 3-acrylyloxypropyltrimethoxysilane and 3-methacryloxypropyltriethoxysilane, 3-isocyanatepropyltriethoxysilane Containing silane coupling agents such as isocyanate group-containing silane coupling agents, and mixtures thereof, but is not limited thereto.

The surface modification of the silica beads is performed by first dissolving the crosslinking agent in a solvent such as alcohols, and then spraying the silica beads to physically adhere the crosslinking agent. Next, the silica beads may be bonded to the silane coupling agent to perform surface modification.

Preferably, the mixture of perhydro polysilazane and silica beads comprises 0.1 to 5 wt% of 100 wt% of the entire surface part composition. When the amount is less than 0.1% by weight, the effect of improving the mechanical properties of the surface portion is insufficient. When the amount is more than 5% by weight, the fluidity of the composition is lowered and the workability may be greatly reduced.
