Figure 1 shows a preferred embodiment of the present invention.

The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which the technical parts already known will be omitted or compressed for simplicity of explanation.

In an embodiment of the present invention, the main ingredient is 25 to 40 parts by weight of the resin solution in which acrylic beads are dissolved in methyl methacrylate and butyl acrylate monomers based on 100 parts by weight of the total coating composition (preferably 30 to 40). Parts by weight).

If the resin solution is less than 25 parts by weight, the adhesion to the concrete and asphalt substrate is inferior, and the adhesion to glass beads is poor, so durability cannot be increased. When the sealing occurs, the appearance of the lane becomes poor.

Here, 35 to 60 parts by weight of acrylic beads are dissolved in 15 to 30 parts by weight of butyl acrylate monomer and 20 to 40 parts by weight of methyl methacrylate based on the total weight of the resin solution (preferably 35 to 45 parts by weight of acrylic beads). 15-25 parts by weight of butyl acrylate monomer and 25-35 parts by weight of methyl methacrylate).

If the acrylic beads are dissolved in less than 35 parts by weight, adhesion to the concrete floor is poor, durability is poor, and the viscosity of the resin solution is low, it is difficult to control the workability of the paint. In addition, when the acrylic beads are dissolved in more than 60 parts by weight, the viscosity of the resin solution is increased, the workability and appearance of the coating film is poor, and the sealing phenomenon and fingering phenomenon occurs during spraying operation to obtain a clean lane.

In this case, it is preferable to use acrylic beads having a glass transition temperature (Tg) of 30 to 90 ° C. and a weight average molecular weight of 50,000 to 100,000. By using the above range, the workability of the paint, the flexibility, and the strength of the coating film are stable. Because it is.

When the butyl acrylate monomer is less than 15 parts by weight or when methyl methacrylate is dissolved at 40 parts by weight or more, the viscosity of the resin solution and the paint is lowered, the strength of the coating film is too strong, and there is a problem of fragility. If it is more than the weight part and methyl methacrylate is dissolved in less than 20 parts by weight, the viscosity may be high and the coating may be so soft that uncured phenomena may occur and durability may be reduced.

On the other hand, the subject according to an embodiment of the present invention is a dispersant and antifoaming agent, reaction stabilizer, paraffin wax solution, benzoyl peroxide room temperature dissociating agent, epoxy acrylate, 3 to improve the physical properties of the coating film, such as workability, drying properties of the paint Functional acrylates, colored pigments, extender pigments, thickeners are further included.

The dispersant is an ammonium salt type, which properly disperses the colored pigment and the extender pigment to improve the hiding power of the coating film and prevents the coating from settling. The antifoaming agent is an acrylic antifoaming agent, which removes air bubbles in the paint during the production or operation of the paint. Improves the appearance of the coating film during drying, and increases durability by eliminating pores in the coating film. The reaction stabilizer uses an antimony system containing a phenyl group and is characterized by adding 0.01 to 0.3 parts by weight depending on the season in the coating composition, which controls the curing time when forming the coating film and prevents the coating from solidifying during storage.

Due to the addition of the benzoyl peroxide room temperature dissociating agent, the double bond of methyl methacrylate and butyl acrylate monomer having double bonds is decomposed, and the coating becomes a gel. This prevents the gel phenomenon of the paint. If the amount of the reaction stabilizer is less than 0.01 parts by weight, the effect is not prevented, and the gel phenomenon of the coating cannot be prevented, the coating film is dried too fast, and the appearance of the coating can be poor, and the amount of the reaction stabilizer is 0.3 parts by weight or more. If the back surface is delayed, the drying becomes difficult.

The paraffin wax solution floats on the surface of the coating film during formation of the coating film to prevent oxygen in the air from reacting with the methyl methacrylate and butyl acrylate monomers, resulting in poor drying and poor durability. It is preferable to use a paraffin wax solution whose melting point is 45-60 degreeC, and it is preferable to contain in 1-5 weight part range. If the amount of the paraffin wax solution is less than 1 part by weight, the oxygen barrier effect may decrease and the coating film may be hardened. If the paraffin wax is more than 5 parts by weight, the lane of the paraffin wax may be slippery.

It is preferable to add 0.3 to 1.5 parts by weight of the benzoyl peroxide dissociation agent. Originally, benzoyl peroxide dissociates above 72 ° C. and reacts with methyl methacrylate and butyl acrylate monomers to form a coating film. However, in practice, since benzoyl peroxide dissociates benzoyl peroxide at room temperature, methyl methacrylate and butyl acryl In order to react with the rate monomer, a benzoyl peroxide room temperature dissociating agent should be added. At this time, if the benzoyl peroxide room temperature dissociation agent is less than 0.3 parts by weight, the dissociation of the benzoyl peroxide is insufficient, so that uncuring occurs. If the content of the benzoyl peroxide is 1.5 parts by weight or more, the gel development of the paint proceeds rapidly and the coating cannot be used.

It is preferable to add 5 to 15 parts by weight of epoxy acrylate, which gives the epoxy properties in the coating film to increase toughness and control the curing rate due to the properties of the acrylate. If the epoxy acrylate content is less than 5 parts by weight, the effect is inferior, the toughness of the coating film is lowered, and the durability is lowered. In addition, when the epoxy acrylate input amount exceeds 15 parts by weight, a sealing phenomenon occurs during spraying of the paint due to the tough properties of the epoxy acrylate, resulting in poor coating appearance.

It is preferable to add 3 to 10 parts by weight of the trifunctional acrylate. By allowing the trifunctional reactor to participate in the reaction, it increases the reactivity after coating to shorten the curing time. If the amount of trifunctional acrylate is less than 3 parts by weight, the effect is insignificant and the reactivity is not increased. If the amount of trifunctional acrylate is more than 10 parts by weight, the coating film becomes too strong, which causes the flexibility to fall off, resulting in cracking or peeling after the time passes. There is concern.

The colored pigment used in one embodiment of the present invention is preferably selected from one or more of colored pigments as an oil, an inorganic pigment.

In addition, the extender pigment is preferably selected from one or more extender pigments such as calcium carbonate, silica sand, mica, silica and the like.

In addition, the thickener is preferably selected from one or more of a silica-based thickener, the thickener serves to properly adjust the viscosity for good workability. These thickeners are also effective in preventing sedimentation of the paint.

The glass beads contained in the drop-type coating composition for preventing drowsiness and speeding are preferably used with a diameter of 0.6 to 1 mm, and when the one having a diameter of 0.6 mm or less is used, the reflex reflection of light is insufficient to be easily reflected to the driver's eyes and 1 mm. When the above is used, the area | region occupied by paint in a coating film reduces, durability falls, and there exists a possibility of peeling of a coating film. In addition, the amount of glass beads is preferably 20 to 25 parts by weight, and when less than 20 parts by weight, high hardness and retroreflective effect of glass beads are inferior. There is a fear of peeling.

It is preferable to use a liquid benzoyl peroxide curing agent having a content of 35 to 50 parts by weight of the benzoyl peroxide powder, and mix about 2 to 5 parts by weight of the total weight of the subject matter, and adjust to spray through a two-head airless spray It is good. This is because when the liquid benzoyl peroxide curing agent is less than 2 parts by weight, the curing may be delayed, and a problem may occur in a fast vehicle passage. There is a risk of falling.

On the other hand, since only a powder curing agent and a paste curing agent are used in Korea, the coating according to the present invention and the spray method using the two-head airless spray cannot be applied.

Therefore, a special silica-based thickener, a phthalate plasticizer, a benzoyl peroxide powder, an aliphatic hydrocarbon-based solvent, a water and a stearate-based reaction stabilizer are mixed and melted and dispersed to prepare a liquid benzoyl peroxide curing agent. Since benzoyl peroxide powder has a strong explosive property, there is a risk of explosion due to friction with a container or an elevated temperature of 70 ° C. or more. As a result, there is little risk of the above-mentioned explosion, and there is an easy effect on the operation of the two-head airless spray.

Referring to the manufacturing method of the coating composition according to a preferred embodiment of the present invention.

First, a paraffin wax having a melting point of 45-60 ° C. is dissolved in methyl methacrylate to prepare a paraffin wax solution. Since the paraffin wax in the solid state must be dissolved above the melting point mentioned above, it must be dissolved in a constant temperature water bath of 60 ° C. or higher and must be prepared before the coating composition is prepared.

At this time, the paraffin wax is preferably dissolved to 40 to 60 parts by weight based on the weight part of methyl methacrylate. If it is less than 40 parts by weight, the oxygen barrier effect is reduced, the curing of the coating film may be poor, and if it exceeds 60 parts by weight, solubility in methyl methacrylate may be limited and may be separated into the original solid state.

On the other hand, the dissolution of paraffin wax used in conventional paints dissolves in toluene, but it is not environmentally friendly, and when the film thickness is over 500 microns during work, the volatilization of toluene becomes difficult due to the solvent trapping phenomenon, so that the coating film may be degraded and the durability may be reduced. There was concern.

Accordingly, in one embodiment of the present invention by dissolving paraffin wax in methyl methacrylate to participate in the reaction with the benzoyl peroxide curing agent, there is no solvent trapping phenomenon, it is possible to prevent the phenomenon that the paint is poor durability due to solvent trapping phenomenon. have.

Next, a resin solution in which acrylic beads are dissolved in a butyl acrylate monomer and methyl methacrylate is prepared. At this time, the acrylic beads should be dissolved in advance in the butyl acrylate monomer and methyl methacrylate excellent in solubility and reactivity with the benzoyl peroxide curing agent. 35 to 60 parts by weight of acrylic beads are dissolved in 15 to 30 parts by weight of butyl acrylate monomer and 20 to 40 parts by weight of methyl methacrylate based on the total weight of the resin solution (preferably 35 to 45 parts by weight of acryl beads 15-25 parts by weight of the monomer and 25 to 35 parts by weight of methyl methacrylate).

 If the acrylic beads are dissolved in less than 35 parts by weight, adhesion to the concrete floor is poor, durability is poor, and the viscosity of the resin solution is low, it is difficult to control the workability of the paint. In addition, when the acrylic beads are dissolved in more than 60 parts by weight, the viscosity of the resin solution is increased, the workability and appearance of the coating film is poor, the sealing phenomenon and fingering phenomenon occurs during the spraying operation can not obtain a clean lane.

A dispersant, an antifoaming agent, a reaction stabilizer, an epoxy acrylate, a paraffin wax solution, a coloring pigment, a sieving pigment, and a thickener are added to the resin solution, and the mixture is stirred and mixed at about 1000 RPM for about 20 to 30 minutes. Then, trifunctional acrylate and liquid benzoyl peroxide room temperature dissociating agent are added and mixed at low speed. At this time, the stirring speed is suitably 500 RPM or less.

Next, the viscosity of the paint is adjusted via methyl methacrylate.

In addition, 20 to 25 parts by weight of glass beads are added to the prepared mixture after the step of adding a trifunctional acrylate and a benzoyl peroxide dissociation agent to prepare a drop-type coating composition for preventing drowsiness and speeding. However, when stirring at a high speed or stirring for a long time, the glass beads are broken and the effect of the glass beads is lowered. Therefore, stirring at a speed of 500 RPM or less in the shortest time (preferably within 5 minutes) is preferable.

On the other hand, such a drop-type coating composition has a higher viscosity than the coating composition for spraying, and as shown in Figure 1 should be formed in the shape of a goggle on the road, the input amount of the above-described raw material may be changed slightly.

<Examples 1 to 3>

Paraffin wax (30 parts by weight) was dissolved in methyl methacrylate (70 parts by weight) in a separate container at 60 ° C. or higher, and acrylic beads (20-45 parts by weight) were dissolved in another container by butylacrylate monomer ( 20 to 45 parts by weight) and methyl methacrylate (20 to 45 parts by weight). A dispersant, an antifoaming agent, a reaction stabilizer, an epoxy acrylate, a paraffin wax solution, a coloring pigment, a sieving pigment, and a thickener are added to the resin solution, and the mixture is stirred and mixed at 1000 RPM for 30 minutes.

Thereafter, trifunctional acrylate and liquid benzoyl peroxide room temperature dissociating agent are added to the aforementioned stirred mixture, followed by stirring and mixing at 500 RPM, and then suitable viscosity is adjusted with methyl methacrylate.

On the other hand, in order to prepare a drop-type coating composition for preventing drowsiness and speeding, trifunctional acrylate and liquid benzoyl peroxide room temperature dissociating agent is added, and then glass beads are mixed and mixed at a low speed. At this time, the content of each composition is as shown in Table 1 below.
