{APPARATUS FOR MARKING LANES}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lane marking apparatus for marking a lane on a road, and more particularly, to a lane marking apparatus for marking lane markings on a road, A glue hopper which is made of a synthetic resin material having heat resistance and chemical resistance in a sloping hopper to be flowed and which can prevent the inclined hopper from being damaged by an acidic or alkaline molten paint flowing in a high temperature state, .

As the number of vehicles increases, a lane has emerged in order to prevent the accident of the vehicle through smooth running and flow of the vehicle. These lanes include a center line that crosses the center of opposite lanes such as highways, national roads, and provincial roads, and a lane that is a lane marking the progress of the vehicle.

The lane of the center line, the driving lane, and the like is a reference line that induces the driver to identify the driving direction so as to induce safe driving of the vehicle. Since the lane is a reference for guiding the safe driving of the vehicle, It can be very important. Since the importance of lane is recognized, new ways of painting lane are studied and actually developed and applied.

An apparatus for painting a lane according to the prior art is composed of an application means for applying the paint on the road surface and a means for mounting and moving the application means. The above-mentioned lane marking apparatus includes a carriage lane marking apparatus for applying a mark on a road surface while an operator pulls a moving means on which the mark is stored, and a vehicle lane marking apparatus for performing a marking operation on the vehicle.

In addition, there are a large number of methods for painting signs such as lane markings and crossing signs on general roads. There are a room temperature type paint painting method, a heating type paint painting method, and a fusion type paint painting method, There is a disadvantage in that the paint is dried at room temperature, the unit cost is low, stable, durability is low, and the service life is short, and the heating type paint painting method is a method of painting using paint, The method of painting using hardening paint at room temperature is more durable than painting using room temperature type paint and has a drawback in that the drying time is short but the nighttime yarn is large and the contamination degree is large. The paint powder was melted at a high temperature of 130 ° C or higher, It has the advantages of durability, fast drying speed, high nighttime yarn and long useful life as compared with the above two methods. Therefore, it is often the case that the specification specifies that the road surface marking should be carried out mainly by a fusing paint method.

In order to increase the visibility of road surface marking during day and night and to prevent accidents due to slipping on the road surface, small diameter glass beads having a particle diameter of 100 to 800 μm and large diameter glass beads having a diameter of 850 to 1,100 μm are mixed and used Although the glass beads are accommodated together with the paint in the paint melting vessel, the glass beads are generally applied to the coating film to be applied to a thickness of 2 mm by a gravitational drop.

Further, the above-mentioned prior art provides a lane diagram aerator having a paint agitator configured to minimize a resistance by a paint when the agitating shaft rotates, thereby minimizing a resistance generated in agitating operation, thereby reducing the fuel for driving the engine .

In the present invention, at least one of the molten paint reservoir (10), the inclined hopper (20), or the auxiliary inclined hopper (21) is formed of a polyether ether ketone copolymer resin The coating layer 70 coated with the coating material may be formed.

That is, the coating layer 70 may include a composition for improving the heat resistance and chemical resistance of the molten paint reservoir 10, the inclined hopper 20, or the auxiliary inclined hopper 21 made of a synthetic resin material, to be.

At this time, the polyether ether ketone copolymer resin, which is the main material of the coating, realizes the effect of realizing heat resistance and chemical resistance to hot or chemical molten paint.

That is, the polyether ether ketone copolymer resin

Or a copolymer resin having the above structure as a basic structure, has a melting point of about 343 DEG C, so that the coating layer 70 of the present invention can exhibit heat resistance, It has a constant viscosity in the state, and is excellent in adhesion.

In connection with the above, the polyetheretherketone copolymer resin exhibits the effect of improving the chemical resistance of the coating layer 70 due to the characteristics of the aromatic polymer.

Also, the coating of the above-mentioned construction can be coated in various ways on each portion of the molten paint reservoir 10, the inclined hopper 20 or the auxiliary inclined hopper 21 where the molten paint flows, It is preferable to form a coating layer 70 having a thickness of 50 to 400 mu m.

If the thickness of the coating layer 70 is less than 50 탆, the thickness of the coating layer 70 is excessively thin. Therefore, when the molten coating material flows frequently, the coating layer 70 is easily worn out and disappears. The thickness of the coating layer 70 is too thick to easily peel off, so that the coating layer 70 preferably maintains the thickness within the above range.

In addition, the coating material may further include an organic-inorganic hybrid polymer in order to improve the adhesion of the polyetheretherketone copolymer resin to the surface of the molten paint reservoir 10, the inclined hopper 20 or the auxiliary inclined hopper 21 Configuration can be performed.

That is, the coating material was prepared by mixing polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) with 100 parts by weight of a polyether ether ketone copolymer resin, And 25 to 40 parts by weight of an organic / inorganic hybrid polymer prepared by mixing 50 to 60% by weight of polytetrafluoroethylene with 40 to 50% by weight of tetraethoxysilane (TEOS).

Specifically, the organic / inorganic hybrid polymer is formed by mixing polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) and tetraethoxysilane (TEOS) , The organic material, polyvinylidene fluoride, co-hexafluoropropylene, and the inorganic material, Si-OH group, have a lattice structure and thus have excellent durability and chemical resistance.

Also, polyvinylidene fluoride co-hexafluoropropylene has excellent heat resistance that can withstand a long time at a high temperature of about 260 DEG C or more, has excellent chemical resistance to a fluid having an acidic or basicity due to a very stable chemical bond, In the state of being made of organic / inorganic hybrid polymer, tetraethoxysilane, which is an inorganic substance, and polyetheretherketone copolymer resin as a main material can be strongly bonded.

In addition, tetraethoxysilane is excellent in heat resistance and chemical resistance because it maintains the physical and chemical properties inherent to silica, including silica, to a certain extent. In addition, the tetraethoxysilane has a lattice structure and bonds with the polyvinylidene fluoride cohexafluoropropylene It is possible to form a hybrid organic / inorganic hybrid polymer.

In addition, tetraethoxysilane can be mixed with polyvinylidene fluoride co-hexafluoropropylene, which is an organic material, in the state of being made of an organic / inorganic hybrid polymer and the surface of the molten paint reservoir 10, the inclined hopper 20 or the auxiliary inclined hopper 21 Can be strongly adhered to each other.

In addition, the organic / inorganic hybrid polymer is preferably blended in a composition ratio of 25 to 40 parts by weight based on 100 parts by weight of the polyetheretherketone copolymer resin as a main component. When the amount of the organic / inorganic hybrid polymer is less than 25 parts by weight, The composition of the hybrid polymer is insufficient and the effect of improving the adhesion between the polyetheretherketone copolymer resin by the organic / inorganic hybrid polymer and the surface of the molten paint reservoir 10, the inclined hopper 20 or the auxiliary inclined hopper 21 becomes insignificant If the amount is more than 40 parts by weight, the composition of the polyetheretherketone copolymer resin may be insufficient and the heat resistance and chemical resistance of the coating layer 70 may be somewhat weakened. Therefore, it is preferable to maintain the composition ratio within the above range.

Also, a method for producing an organic / inorganic hybrid polymer is characterized in that 15 to 25% by weight of polyvinylidene fluoride cohexafluoropropylene is dissolved in 75 to 85% by weight of dimethylacetamide to prepare an organic polymer solution, and 35 to 45 wt% of tetraethoxysilane % Of ethanol was dissolved in 55 to 65 wt% of tetraethoxysilane solution to prepare a solution of an inorganic polymer solution obtained by hydrolyzing 2 to 5 times of the weight of tetraethoxysilane solution, and then the organic polymer solution was mixed with 50 to 60 wt% By weight and 40 to 50% by weight of an inorganic polymer solution.

In order to accelerate the hydrolysis of the tetraethoxysilane by the distilled water, the inorganic polymer solution may be prepared by further mixing 0.03 to 0.3 times the weight of the tetraethoxysilane solution with hydrochloric acid.

The coating material according to the present invention may be coated with a solvent, a viscosity adjusting agent, a curing agent, an antioxidant, or the like according to a method of forming the coating layer 70 on the molten paint reservoir 10, the inclined hopper 20, or the auxiliary inclined hopper 21 made of metal or synthetic resin. Or antifoaming agents, and the like. That is, when coating the liquid coating material directly on the molten paint reservoir 10, the inclined hopper 20, or the auxiliary inclined hopper 21 and coating the coating, the coating composition may be coated with a coating agent such as a solvent, a viscosity adjusting agent, General additives may be added in a general composition ratio.

As shown in FIG. 5, the bead sprayer 40 according to the present invention is located behind the storage tank 30 in which the molten paint is discharged, and the powdered bead is applied to the upper portion of the molten paint applied on the road. A part of scattered beads are adhered (adsorbed) to the rear outer side of the storage tank 30 and the discharge port 31 of the storage tank 30 is adhered to the outer side of the storage tank 30 A part of the scattered beads and the molten paint may be adhered to the rear outer side of the storage tank 30. In this case,

On the other hand, in the present invention, the ionic coating layer 80 may be formed as a polyacrylic acid (PAA), which is an ionic material, on the outer side of the rear of the storage tank 30.

That is, when the polyacrylic acid is coated as an anionic polymer on the rear outer side of the storage tank 30 and cured, the coating layer 70 is anionically dispersed, and anionic beads in the air are bonded to the storage tank 30, It is possible to prevent the rear end portion of the rear end portion from being sucked.

In addition, polyacrylic acid-seeded polymer electrolyte materials having an anionic property are more preferably those having an average molecular weight of 15,000 to 250,000 Da. At this time, the polyacrylic acid has an excellent coating effect on the surface of the molten paint reservoir 10, the inclined hopper 20 or the auxiliary inclined hopper 21 as a polymer acrylic acid.

If the average molecular weight of the polyacrylic acid is less than 15,000 Da, the molecular weight of the polyacrylic acid is too light, and the coating force on the surface of the molten paint reservoir 10, the inclined hopper 20 or the auxiliary inclined hopper 21 is somewhat insufficient The coating strength on the surface of the molten paint reservoir 10, the inclined hopper 20 or the auxiliary inclined hopper 21 is excellent, but the molten paint reservoir 10, the inclined hopper 20 ) Or the process of coating the surface of the auxiliary inclined hopper 21 with the polyacrylic acid becomes difficult. Therefore, it is preferable to use those having an average molecular weight within the above range.

In connection with the above, the polyacrylic acid seed may be dissolved in a sodium salt solution to obtain a certain viscosity.

In addition, the polyacrylic acid having the above-described structure may be coated in various ways on the outer side of the rear side of the storage tank 30 and coated with a general coating, spraying or impregnating method to form a polyacrylic acid coating layer 70 of 50 to 400 탆 .

If the thickness of the polyacrylic acid coating layer 70 is less than 50 탆, the thickness of the polyacrylic acid coating layer 70 is too thin, and the polyacrylic acid coating layer 70 is formed by beads, If the thickness of the polyacrylic acid coating layer 70 is too thick, the polyacrylic acid coating layer 70 may have a thickness within the above range because the polyacrylic acid coating layer 70 may be easily peeled off. .
