2-COMPONENTS COLD PLASTIC TYPE PAINT COMPOSITION FOR A ROAD MARKING WITH IMPROVED VISIBILITY IN CASE OF RAIN}

The present invention relates to a two-component, room temperature curing type coating composition for road surface marking with improved visibility in rainy weather, and more particularly, it can be used as a two-part type room temperature curing type coating composition, and a two-part type coating composition for road surface marking having excellent visibility in rainy weather, and It relates to its manufacturing method.

With the development of transportation means and the increase in the spread of automobiles, the need to transmit more information from the road surface to the driver has increased. In general, road lanes are used not only as indicator lines to guide the direction so that vehicles running on the road can safely move, but also destination information about speed limits and traveling directions are directly applied and displayed on the road surface. Marking paints have been developed and used in various types, and especially in special areas with dangers such as bus lanes, children's protection areas, road slip prevention, slopes or in front of schools, to increase driver visibility. The road surface is painted in various forms.

The paints used at this time can be classified according to the raw material component and construction method, and can be classified into room temperature drying type road surface marking paint, water-soluble road surface marking paint, heating type road surface marking paint, and fusion type road surface marking paint.

More specifically, 1 type is a room temperature drying type coating mainly composed of room temperature type paint coloring pigments, extender pigments and synthetic resin varnishes, and 2 types are water-soluble road sign paint coloring pigments, extender pigments and water-soluble resins. It is a water-soluble paint as the main raw material, and three types are paints used by heating colored pigments, extender pigments and synthetic resin varnishes as main ingredients, and four types are road coloring pigments for fusion-type road signs, extender pigments, and glass. It is a paint used by heating and melting beads, filling material, and synthetic resin as the main raw materials.

On the other hand, the paint for road marking must have excellent adhesion to road surfaces such as asphalt and concrete, and has excellent adhesion to glass bead, which makes the road sign clear by reflecting light on night or dark roads. In addition, the abrasion resistance of the road sign must be excellent by allowing the paint composition to penetrate into the road made of asphalt or concrete, and the time to limit the passage of moving objects and pedestrians must be short during the road painting work. It should be fast.

In addition, by allowing the paint composition to penetrate into the road made of asphalt or concrete, the abrasion resistance of the road surface should be excellent, and the visibility should be excellent in rainy weather.

In addition, the road surface may cause cracks due to penetration of rainwater, and these cracks are intensified by the impact of the vehicle load and become a pit.At this time, if such cracks and pits are formed in the part where the road surface is formed, road users should be careful. Matters, regulations, instructions, etc. are not well known to road users, which can lead to serious safety problems.

Among these road marking paints, the two-component paint is a lane paint for concrete and asphalt, which has excellent mechanical and chemical properties of the coating film when cured by using acrylic resin as a matrix and has a very fast drying time. As a prior art for a two-component road sign paint composition, in Korean Patent Publication No. 10-2013-0037392 (2013.04.16.), acrylic beads are used as methyl methacrylate (MMA) to improve the adhesion and durability of the paint. ) And a resin solution prepared by dissolving in an acrylic monomer of a butyl acrylate monomer (BAM); And a curing agent containing benzoyl peroxide (Benzoyl peroxide, BPO) prepared in a liquid phase; It describes a two-component coating composition for road signs including, and in Patent Publication No. 10-1814346 (2018.01.04.), a composite acrylic resin and a bifunctional acrylic resin, a dispersant, a stabilizer, a reaction accelerator, and a fluidity modifier are described. , A thickener, a coloring pigment, an extender pigment, and the main components are benzoic acid branched alkyl ester, benzoyl peroxide, and the reaction product of dichlorodimethyl by silica (Dichlorodimethylsiline: reaction products with silica), octadecanoic acid zinc salt (Octadecanoic acidzinc salt), including a curing agent consisting of two-component road surface coating composition is described.

However, despite the prior art including the prior literature, cracks due to impact and friction are still occurring in the lane, and the water repellency and abrasion resistance are more improved without fear of being damaged by rain or snow due to strong humidity in rainy weather. There is a continuous demand for the development of a two-component road marking coating composition.

As a specific example, N-(β-aminoethyl)-γ-aminopropylmethyldimethoxy silane, 3-methacryloyloxy propyltris trimethylsiloxy silane N-(β-aminoethyl)-γ-aminopropylmethyldi Methoxy silane, γ-aminopropyltridimethoxy silane and γ-aminopropyltridiethoxy silane, vinyl triethoxy silane, vinyl triisopropyl silane, may be any one or a mixture thereof, preferably vinyl Triethoxysilane or vinyl triisopropylsilane can be used.

The amino silane has an organic container that binds to an organic material and a hydrolyzable group that reacts with an inorganic material in the same molecule, and thus plays a role in binding both, and paints (organic) and glass particles ( Inorganic) can be generally used to improve mechanical adhesion and water resistance.

In addition, the reactive resin composition in the present invention may additionally contain 3 to 20 wt% of a urethane acrylate oligomer together with a silane coupling agent as an adhesion promoter, based on the total components of the reactive resin composition.

The urethane acrylate oligomer may be obtained by copolymerization of a polyol with a diisocyanate and an acrylate, wherein the polyol is selected from polyethylene glycol (PEG) or polypropylene glycol (PPG) or polytetramethylene glycol (PTMG) Is any one

The diisocyanate is PPDI (p-pthnylene diisocyanate), HDI (1,6-Hexamethylene diicosyanate, TDI (Toluene diicosyanate), NDI (1,5-Naphthalene diisocyanate) IPDI (Isoporon diisocyanate), MDI (4,4-Diphenylmethane diisocyanate) ), Cyclohexylmethane diicosyanate) Any one selected from among, and preferably, an aliphatic isocyanate with less yellowing and an advantageous exothermic reaction control IPDI may be used, and the acrylate may be selected from 2-ethylhexyl acrylate or 2-hydroxy ethyl methacrylate. It can be any one selected.

Further, as the polyol, propylene glycol can be used in a molecular weight of 400 to 3000, and preferably has a molecular weight of about 800 to 1500.

In addition, in the case of the subject matter in the present invention, in addition to the reactive resin composition, a coloring pigment, an extender pigment, a dispersant, finely divided silica, a UV stabilizer, and calcium carbonate may be included.

Here, the colored pigment embodies the color of the paint, has the effect of imparting coloring and hiding power of the paint, and has a color that withstands sunlight without dissolving in water, oil, and solvent, and can be used separately according to function and purpose. It can be divided into inorganic and organic pigments.

The inorganic pigments include metal compounds such as titanium, lead, copper, iron, and chromium, and carbon black made by incomplete combustion of petroleum or natural gas is also included, and organic pigments are in the form of metal compounds that do not dissolve dyes in water or solvents. It is possible to prevent dissolving in water and solvent by dyeing the raw material and extender pigment with dye.

According to the present invention, a colored pigment is prepared including 4 to 30% by weight of a colored pigment based on the total composition of the subject. If the coloring pigment is less than 4% by weight, the coloring and hiding power of the paint is lowered, and when it exceeds 30% by weight, wettability and adhesion are poor, and the viscosity of the paint composition increases, resulting in poor productivity and workability. do.

The dispersant may be selected from one or more dispersants for organic inorganic pigments as a wetting dispersant. The dispersant improves the dispersion of the pigment and extender pigment in the paint, thereby improving the visual effect and hiding power of the coating film, and may affect the storage stability of the paint.

The content of the dispersant is prepared including 0 to 0.5% by weight of the dispersant based on the total composition of the subject. When the dispersant exceeds 0.5% by weight, the dispersing effect may not increase proportionally in proportion to the increase of the dispersant content.

In addition, finely divided silica improves durability and enhances the strength of the coating film through reaction with silane.

According to the present invention, the finely divided silica is prepared including 5 to 30% by weight of finely divided silica based on the total composition of the subject. When the finely divided silica is less than 5% by weight, the effect of enhancing the strength of the coating film is insignificant, and when it exceeds 30% by weight, the viscosity increases, resulting in a problem that is not beneficial to workability.

On the other hand, in the case of calcium carbonate, as a spherical filler, it can improve flowability and increase whiteness.

According to the present invention, calcium carbonate is prepared including 5 to 30% by weight of an extender pigment based on the total composition of the subject.

The extender pigment can be selected from one or more extender pigments such as calcium carbonate, talc, silica sand, mica, kaolin, etc., and the extender pigment is effective in controlling physical properties such as fluidity and viscosity of the paint and controlling the strength, durability, and gloss of the coating film. There is.

According to the present invention, the extender pigment is prepared including 0 to 30% by weight of the extender pigment based on the total composition of the subject. When the extender pigment exceeds 30% by weight, a problem of deteriorating the storage stability of the paint may occur.

In addition, the UV stabilizer prevents premature deterioration due to ultraviolet rays, and the UV stabilizer is prepared including 0 to 2% by weight of a UV stabilizer based on the total composition of the subject. When the UV stabilizer exceeds 2% by weight, the deterioration prevention effect may not be improved any more.

In addition, the present invention provides a method of forming a coating film for road surface marking by applying the above-described coating composition for road surface marking to a road, and a coating film for road surface marking obtained by using the above-described coating composition for road surface marking.

On the other hand, in the case of the two-component coating (5 types), the coating material is quickly dried by the main material and the curing agent, and a peroxide-based curing agent for radical polymerization may be used as the curing agent component.

In addition, as a preferred embodiment of the present invention, in the two-part type coating composition for road surface marking comprising a reactive resin composition, a coloring pigment, a dispersant, a subject comprising finely divided silica and calcium carbonate; and a curing agent; the reactive resin composition Based on the total components of the reactive resin composition, 30 to 50 wt% of an acrylate or methacrylate polymer copolymerized with a fluoromonomer compound having a double bond is included, and the subject is a reactive resin composition 20 based on the total composition of the subject. It contains ~ 45% by weight, color pigment 4 ~ 30% by weight, dispersant 0 ~ 0.5% by weight, finely divided silica 5 ~ 30% by weight, and calcium carbonate 5 ~ 30% by weight, additionally 0 ~ 30% by weight of extender pigment and UV stabilizer It provides a two-component coating composition for road surface marking, characterized in that it contains 0 ~ 2 wt%.

Evaluation Example 3.

In addition, by using the samples of Examples 1 to 6 and Comparative Example 1, the quality was evaluated to be equivalent to or conforming to the regulations of KS M 6080:2014. The evaluation items were luminance rate (β), luminance change rate after aging test (Δβ) abrasion resistance, pencil hardness, alkali resistance, water resistance, and surface water repellency, and the abrasion resistance evaluated the result (300 mg or less) for 100 revolutions of wear loss. The alkali resistance should not be cracked or discolored even when immersed in a saturated calcium hydroxide solution for 18 hours, and the surface water repellency was prepared by adding a 0.1% volume ratio soap solution in 10L clear water referring to the wet road evaluation conditions of KSM 6080 5.2.16. 10L of water was poured at a height of 0.5m for 30 seconds to check the amount of water remaining on the surface after 1 minute to evaluate the water repellency. The evaluated physical property evaluation results are shown in Table 4 below.

[Table 4]

According to Table 2, the initial retroreflectivity grades of Examples and Comparative Examples in the present invention show high performance on a wet road surface, but it can be seen that the retroreflectivity decreases as the wear resistance test proceeds, and the wear resistance results of the examples Was found to be much better than the comparative example.

More specifically, the coating composition according to Examples 1 to 6 of the present invention showed a relatively gentle decrease in performance in the retroreflectivity evaluation result, whereas the result of the Comparative Example showed a sharp decrease in performance compared to the Example.

That is, it can be seen that the paint prepared by using the reactive resin composition according to the present invention under the same conditions has improved surface water repellency, so that the lane retroreflectivity in rainy weather is superior to that of the comparative example.

In addition, as a result according to Table 3 above, the grade of retroreflectivity in the dry drawing shows the highest performance at the beginning, but it can be seen that the retroreflectivity decreases as the wear resistance test proceeds. It can be seen that the performance drops sharply.

That is, even on a dry road surface, it can be confirmed that the retroreflective property of the paint prepared using the reactive resin composition according to the present invention is superior to that of the comparative example.In particular, as the content of the fluorine monomer compound is increased, the silane monomer compound is added. It can be done that the retroreflectivity of the composition exhibits much superior properties.

In addition, as a result of Table 4, it can be seen that the coating composition according to Examples 1 to 6 showed improved performance compared to the comparative example as a result of measuring the luminance ratio, hardness, abrasion resistance, water resistance, and surface water repellency properties. Examples 5 and 6 show that the silane monomer having a double bond is additionally copolymerized with the polymer in which the fluorine monomer compound is copolymerized, thereby enhancing the coating strength, water resistance, and surface water repellency, thereby showing the best luminance characteristics on wet roads and dry roads. .
