Description

TECHNICAL FIELD [0001] The present invention relates to a two-component paint composition for road marking,

The present invention relates to a two-pack coating composition for road marking.

Generally, the road surface is marked with the lane marking using paint for paint marking (lane marking) for the purpose of boundary direction between the lane and the lane. Conventional road marking paints are KSM 6080 type 1 (oil type) and 2 types (aqueous type), and one kind or two kinds of room temperature curing type paints are paints which are dried on the road surface by volatilization of the solvent in the products .

Also, as a related art, Korean Patent Application No. 10-2009-0062266 (published on January 14, 2011) is available.

However, the conventional room temperature curable type oil paint (1 kind) and the water-soluble paint (2 kinds) are delayed in drying and it takes much time to pass the vehicle, which can cause traffic congestion and the durability and adhesiveness of acrylic resin itself is poor, The performance of fixing the glass bead is lowered.

As a result, conventional paints cause a phenomenon in which a lane is hardly visible to a driver at night or in a rainy day, and this has a great effect on causing traffic accidents. Further, since the abrasion resistance and the durability are poor, it is necessary to perform the repair coating once a year, which requires additional expenses. Therefore, a new room-temperature curing type plastic paint was newly added to the road surface marking paint, which is a lane marking material supplied in single or multiple component form. Depending on the type of system, the various components are mixed in varying proportions and applied with suitable painting equipment. It is a film-formed product adhered to the surface only by chemical reaction. Currently, a paint using MMA resin is used, which is a system that is cured with the original heat, which uses a catalyst, expressed as a tertiary amine, to allow room temperature curing at the site. However, the reaction can be smoothly carried out as long as the amount thereof is large. The tertiary amines have a strong yellowing property when they are cured and hardened, and when they are painted in white lanes, they show yellowing over time. In this case, the reflectivity of the glass bead is lowered and the inherent whiteness of the lane is lowered. Therefore, there is a possibility of causing an accident due to difficulty in securing the driver's vision for the purpose of the lane in the rain or at night.

The present invention has been made in order to overcome the above problems, and it is an object of the present invention to provide a paint composition which can be rapidly dried for 5 minutes to 10 minutes, has good whiteness of color, has no color change, And to provide a technique capable of producing a paint excellent in adhesion with glass beads.

According to the present invention, there is provided a method for improving the adhesion and durability of paints sprayed on a road formed of concrete or asphalt, comprising the steps of: mixing acrylic beads with methyl methacrylate (MMA) and butyl acrylate monomers a main agent comprising a resin solution prepared by dissolving an acrylate monomer (BAM) in an acrylic monomer; An epoxy-based highly reactive resin; And a curing agent comprising benzoyl peroxide (BPO) prepared in the form of a liquid.

Here, the above-mentioned two-pack coating composition for road marking is a paraffin wax solution or a coloring pigment or extender pigment or thickener dissolved in a dispersing agent or defoaming agent or a reaction stabilizer or a liquid benzoyl peroxide room temperature dissociation agent or methyl methacrylate or a trifunctional acrylate As shown in FIG.

The reaction stabilizer may be an antimony-based reaction stabilizer containing a phenyl group.

Here, the resin solution may be composed of 25 to 40 parts by weight based on 100 parts by weight of the total coating composition.

The liquid phase benzoyl peroxide room temperature dissociation agent is contained in an amount of 0.1 to 0.2 parts by weight, the paraffin wax solution is contained in an amount of 1 to 5 parts by weight based on 100 parts by weight of the total paint composition, 5 to 20 parts by weight of the epoxy-based highly reactive resin, 3 to 10 parts by weight of the trifunctional acrylate, 0.3 to 1.0 part by weight of the thickener, 5 to 20 parts by weight of the colored pigment, The extender pigment may be composed of 25 to 50 parts by weight.

Here, the acrylic bead has a glass transition temperature (Tg) of 30 to 90 DEG C and a weight average molecular weight of 50,000 to 100,000.

Further, the curing agent containing the benzoyl peroxide is mixed in a weight ratio of 98: 2 to 5 to the subject containing the resin solution.

On the other hand, the liquid benzoyl peroxide curing agent contains 35 to 50 parts by weight of benzoyl peroxide powder; 10 to 30 parts by weight of a phthalate plasticizer; 5 to 10 parts by weight of an aliphatic hydrocarbon-based solvent; 5 to 10 parts by weight of water; 1 to 5 parts by weight of a silica-based anti-settling agent; And 1 to 5 parts by weight of a stearate reaction stabilizer.

As described above, the present invention has the following effects.

First, it contains acrylic beads excellent in adhesiveness and durability to roads and acrylic monomer excellent in reactivity, and contains epoxy-based highly reactive resin, so that a liquid benzoyl peroxide curing agent and a small amount of liquid benzoyl peroxide room temperature dissociation agent (Tertiary amine) is added, the whiteness is superior to that of the conventional paints, so the visibility of the driver is very good, which is very helpful for safe driving and has excellent resistance to sulfurization, so that the color of the coating film does not change with the lapse of time Whiteness can be maintained for a long time after painting.

Secondly, by using the epoxy-based highly reactive resin, the tensile strength of the coating film is improved and the property of fixing the glass bead is excellent compared with the composition using the conventional epoxy acrylate. As a result, the high reflection luminance lasts for a long time, and the visibility of the driver is prolonged for a long time, which also greatly influences the maintenance period of the road marking paint, thereby significantly reducing the cost and time for repairing.

Third, by using an epoxy-based highly reactive resin. The use amount of the tertiary amine can be remarkably reduced. This can eliminate the fear of discoloration due to excessive use of tertiary amine. In addition, when the tertiary amine is used in an excess amount, the elongation of the coating film is lowered so that it can not withstand the shrinkage and expansion according to the temperature of the asphalt, . Therefore, by using only a small amount of tertiary amine, the elongation of the coating film is prevented, thereby increasing the elongation of the coating film, thereby softening the coating film and preventing peeling and cracking of the coating film, have.

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

Prior to this, the terms used in the specification and claims should not be construed in a dictionary sense, and based on the principle that the inventor can properly define the concept of a term in order to explain its invention in the best way, And should be construed in light of the meanings and concepts consistent with the technical idea of the present invention.

Therefore, the constitution described in the present specification is merely a preferred embodiment of the present invention, and not all of the technical ideas of the present invention are expressed, so that various equivalents and modifications may be made at the time of filing of the present application .

The two-pack type paint composition for road marking according to the present invention is characterized in that acrylic beads are mixed with methyl methacrylate (MMA) and butyl acrylate to improve adhesion and durability of a paint sprayed on a road formed of concrete or asphalt for a lane, A main agent comprising a resin solution prepared by dissolving an acrylic monomer of a butyl acrylate monomer (BAM); An epoxy-based highly reactive resin; And a curing agent comprising benzoyl peroxide (BPO) prepared in a liquid phase.

In one embodiment of the present invention, the above-mentioned subject matter includes 25 to 40 parts by weight (preferably 30 to 40 parts by weight) of a resin solution in which acrylic beads are dissolved in methyl methacrylate and butyl acrylate monomers on the basis of 100 parts by weight of the total coating composition, Lt; / RTI >

If the amount of the resin solution is less than 25 parts by weight, adhesion with concrete and asphalt paper is poor, and adhesion with glass beads is poor. Therefore, the durability can not be enhanced for the intended purpose. When the amount exceeds 40 parts by weight, A silking phenomenon occurs and the appearance of the lane becomes poor.

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 to 25 parts by weight of butyl acrylate monomer and 25 to 35 parts by weight of methyl methacrylate).

If the acrylic beads are dissolved in less than 35 parts by weight, the adhesion to the concrete floor is poor, durability is poor, and the viscosity of the resin solution is low, making it difficult to control the workability of the paint. In addition, if the acrylic beads are dissolved in an amount exceeding 60 parts by weight, the viscosity of the resin solution becomes high, so that the workability and the appearance of the coating film become poor, and a silk lane can not be obtained due to a sealing phenomenon and a fingering phenomenon during spraying.

The acrylic beads preferably have a glass transition temperature (Tg) of 30 to 90 DEG C and a weight average molecular weight of 50,000 to 100,000. When the range is satisfied, the workability, flexibility, and strength of the coating film are stable .

When the amount of the butyl acrylate monomer is less than 15 parts by weight or when the methyl methacrylate is dissolved in an amount of not less than 40 parts by weight, the viscosity of the resin solution and the coating becomes low and the strength of the coating film becomes too strong, When the amount of the methyl methacrylate is less than 20 parts by weight, the viscosity of the composition is increased and the coating film is excessively backed, resulting in the occurrence of uncured and durability.

Meanwhile, in order to improve the physical properties of the coating film such as workability and dryness of the paint, a subject such as a dispersant, a reaction stabilizer, a paraffin wax solution, a benzoyl peroxide room temperature dissociation agent, an epoxy-based highly reactive resin, Functional acrylates, coloring pigments, extender pigments, and thickeners.

The dispersant is an ammonium salt type which improves the hiding power of the coating and prevents the sedimentation of the paint by appropriately dispersing the color pigment and the extender pigment. The antimony compound containing the phenyl group is used as the reaction stabilizer, and 0.01 To 0.3 part by weight, the curing time is controlled during the formation of the coating film and the coating is prevented from hardening during storage.

The introduction of benzoyl peroxide at room temperature dissociation causes decomposition of the double bonds of the methyl methacrylate and butyl acrylate monomers having a double bond, resulting in a phenomenon that the paint becomes a gel. At this time, Thereby preventing the gel phenomenon of the paint. If the amount of the reaction stabilizer is less than 0.01 part by weight, the effect of the reaction stabilizer can not be prevented and gelation of the coating material can not be prevented. As a result, the coating film becomes too dry and the appearance of the coating film becomes poor. The drying of the coating film is delayed, which makes it difficult to dry quickly.

The paraffin wax solution floats on the surface of the coating film when the coating film is formed, and oxygen in the air reacts with methyl methacrylate and butyl acrylate monomers to prevent drying failure and durability deterioration. The paraffin wax solution preferably has a melting point of 45 to 60 ° C, preferably 1 to 5 parts by weight. 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 0.1 to 1.2 parts by weight of benzoyl peroxide at room temperature dissociation agent (tertiary amine). Originally, benzoyl peroxide dissociates at 72 ° C or higher and reacts with methyl methacrylate and butyl acrylate monomers to form a coating film. However, since it is room temperature curing at the actual site, benzoyl peroxide is dissociated at room temperature to form methyl methacrylate and butyl acrylate The benzoyl peroxide room temperature dissociation agent must be added to react with the rate monomer. If the benzoyl peroxide room temperature dissociation agent is less than 0.1 part by weight, dissociation of benzoyl peroxide may be insufficient and uncrosslinked. If the amount of benzoyl peroxide is more than 0.2 parts by weight, the color of the coating film may turn yellow, There is a fear that acceleration may occur.

It is preferable to add 5 to 20 parts by weight of the epoxy-based highly reactive resin used as the additive agent, which increases the reactivity and does not affect the workability and appearance, unlike the general epoxy-based resin. By using the epoxy-based highly reactive resin, the amount of the tertiary amine can be remarkably reduced, thereby increasing the whiteness of the coating film and preventing the yellowing of the coating film. Therefore, the gel phenomenon of the paint can be eliminated. General epoxy-based acrylates increase the toughness and can not adjust the amount of tertiary amines or the breakage of the coating film. In addition, since the viscosity is high, a cracking phenomenon or paint flaking may occur during operation. When the amount of the epoxy-based highly reactive resin is less than 5 parts by weight, the reactivity can not be shortened, which is not meaningful to use. If the amount is more than 20 parts by weight, the coating film becomes too strong.

It is preferable to add 3 to 10 parts by weight of trifunctional acrylate. By allowing the trifunctional reactor to participate in the reaction, the curing time is shortened by increasing the reactivity after coating. If the amount of the trifunctional acrylate is less than 3 parts by weight, the effect is insufficient and the reactivity is not increased. If the amount of the trifunctional acrylate is more than 10 parts by weight, the coating becomes too strong and the flexibility becomes poor, There is a concern.

The coloring pigment used in one embodiment of the present invention is preferably selected from at least one of colored pigments as an oil and an inorganic pigment, and the extender pigment is preferably at least one selected from extender pigments such as calcium carbonate, silica sand, mica, silica and the like Do.

In addition, it is preferable to select at least one silica-based thickener as the thickener, and the thickener appropriately controls the viscosity for good workability. Such a thickener is also effective in preventing sedimentation of the paint.

The liquid benzoyl peroxide curing agent is preferably used in an amount of 30 to 50 parts by weight of benzoyl peroxide powder and is mixed in about 2 to 5 parts by weight in the total weight portion of the liquid composition and is adjusted to be sprayed through a 2-head airless spray It is good. If the amount of the liquid benzoyl peroxide curing agent is less than 2 parts by weight, the curing may be delayed, resulting in a problem in fast vehicle passing. If the amount of the liquid benzoyl peroxide curing agent exceeds 5 parts by weight, the reactivity becomes very high, May fall.

On the other hand, since only a powder hardener and a paste hardener are used in Korea, it can not be applied by a spraying method using a two-head airless spray according to the present invention.

Therefore, in order to prepare a liquid benzoyl peroxide curing agent, a silica-based anti-settling agent, a phthalate-based plasticizer, a benzoyl peroxide powder, an aliphatic hydrocarbon-based solvent, a water and a stearate-based reaction stabilizer are mixed and mixed and dispersed. The benzoyl peroxide curing agent according to the present invention can be prepared in liquid form because the benzoyl peroxide powder has a strong explosive property, and therefore there is a risk of explosion due to friction with the container or a temperature rise of 70 ° C or more. There is almost no danger of the explosion described above, and there is an effect of facilitating the operation of the two-head airless spray.

A method of preparing a coating composition according to a preferred embodiment of the present invention will be described below.

A method for producing a falling type coating composition for preventing drowsiness and overspeed according to a preferred embodiment of the present invention will be described below.

A step of dissolving acrylic beads in an acrylic monomer of methyl methacrylate and butyl acrylate monomers to prepare a resin solution; A step B of dissolving paraffin wax in methyl methacrylate to prepare a paraffin wax solution; A step C of adding a dispersant to the resin solution prepared in the step A; A step D for mixing the paraffin wax solution prepared in the step B with the mixture prepared in the step C; Step E in which a reaction stabilizer is added to the mixture prepared in step D; An F step of mixing the mixture prepared in the step E with a coloring pigment and an extender pigment; A step G for mixing a thickener with the mixture prepared in the step F; An H step of mixing an epoxy-based highly reactive resin with the mixture prepared in step G; An I step of mixing trifunctional acrylate with the mixture prepared in step H; And a step J for mixing liquid benzoyl peroxide room temperature dissociation agent (tertiary amine) with the mixture prepared in the step I, and in the step B, the paraffin wax having a melting point of 45 to 60 DEG C is mixed with the methyl methacrylate And mixing the glass beads with the mixture prepared in step J, wherein the glass beads are prepared to prepare the paraffin wax solution.

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

At this time, the paraffin wax is preferably dissolved in an amount of 40 to 60 parts by weight based on the weight of methyl methacrylate. If the amount is less than 40 parts by weight, the oxygen shielding effect may be deteriorated and the curing of the coating film may be poor. If the amount is more than 60 parts by weight, the solubility in methyl methacrylate may be limited.

On the other hand, dissolution of paraffin wax used in conventional paints dissolves in toluene, but it is not environmentally friendly. When the coating thickness is 500 microns or more at work, volatilization of toluene becomes difficult and the coating film is retracted due to trapped solvent, There was concern.

Accordingly, in the preferred embodiment of the present invention, the paraffin wax is dissolved in methyl methacrylate to participate in the reaction with the benzoyl peroxide curing agent, thereby preventing the solvent trapping phenomenon and preventing the durability of the paint due to the solvent trapping phenomenon .

Next, a resin solution in which acrylic beads are dissolved in butyl acrylate monomer and methyl methacrylate is prepared. At this time, since acrylic beads are solid phase, they should be dissolved in methyl acrylate and butyl acrylate monomers excellent in solubility and reactivity with 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 acrylic beads, 15 to 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, the adhesion to the concrete floor is poor, durability is poor, and the viscosity of the resin solution is low, making it difficult to control the workability of the paint. In addition, if the acrylic beads are dissolved in an amount exceeding 60 parts by weight, the viscosity of the resin solution becomes high, so that the workability and the appearance of the coating film become poor, and the sealing and fingering phenomena occur during the spraying operation.

Next, a dispersing agent, a reaction stabilizer, an epoxy-based highly reactive resin, a paraffin wax solution, a coloring pigment, an extender pigment, and a thickening agent are added to the resin solution and stirred at about 1000 RPM for about 20 to 30 minutes. Then, trifunctional acrylate and liquid benzoyl peroxide room temperature dissociation agent are introduced and mixed at a low speed. At this time, the stirring speed is preferably 500 RPM or less.

Next, the viscosity of the coating material is controlled through methyl methacrylate.

≪ Examples 1 to 3 >

Paraffin wax (30 parts by weight) was dissolved in methyl methacrylate (70 parts by weight) in a separate vessel at 60 占 폚 or higher and acrylic beads (20 to 45 parts by weight) were dissolved in a separate vessel to prepare butyl acrylate monomer 20 to 45 parts by weight) and methyl methacrylate (20 to 45 parts by weight). To this resin solution, a dispersing agent, a reaction stabilizer, an epoxy-based highly reactive resin, a paraffin wax solution, a coloring pigment, an extender pigment, and a thickening agent are added and stirred at 1000 RPM for 30 minutes.

Then, trifunctional acrylate and liquid benzoyl peroxide room temperature dissociation agent are added to the above-mentioned stirring mixture, and the mixture is stirred at 500 RPM, and then a suitable viscosity is controlled by methyl methacrylate.
