At this time, unless there is another definition in the technical terms and scientific terms used, they have meanings commonly understood by those of ordinary skill in the art to which this invention belongs, and the gist of the present invention in the following description and accompanying drawings Descriptions of well-known functions and configurations that may be unnecessarily obscure are omitted.

First, one aspect of the present invention is a subject comprising an amine group terminal prepolymer prepared by reacting an alicyclic polyisocyanate and an alicyclic primary polyamine, a polyaspartic acid ester, and a surface-modified zeolite; And a curing agent containing an aliphatic polyisocyanate; it relates to a coating composition for ultra-quick-curing polyurea road markings comprising a.

There is an advantage in that the beads are firmly adhered to the coating film and excellent visibility can be secured.

Hereinafter, each component of the ultra-quick-curing polyurea road surface coating composition according to an embodiment of the present invention will be described in more detail.

As described above, the paint composition according to one embodiment of the present invention may be a two-component paint composition largely composed of a main agent and a curing agent. The weight ratio of the subject:curing agent may be 100:10 to 100, more preferably 100:20 to 70, and more preferably 100:30 to 50. In this range, the subject and the curing agent react well to form a solid road surface coating film.

A subject according to an embodiment of the present invention may include an amine group terminal prepolymer prepared by reacting alicyclic polyisocyanate and alicyclic primary polyamine, polyaspartic acid ester, and surface-modified zeolite.

In one example of the present invention, the amine group-terminated prepolymer means a polymer prepared by stopping the polymerization reaction in a relatively low polymerization degree state for initial fast curing, in the present invention, alicyclic polyisocyanate and alicyclic primary polyamine It may be prepared by reacting. By preparing the alicyclic polyisocyanate and the alicyclic 1-polyamine prepolymer as described above, it is possible to have super-fast curing properties when forming a road surface coating film. At this time, the amine equivalent of the amine group terminal prepolymer prepared by the polymerization reaction may be 150 to 100 g / eq, and more preferably 160 to 180 g / eq.

In addition, it is preferable to use an excessive amount of alicyclic primary polyamine relative to the number of moles of alicyclic polyisocyanate in order to form an amine group at the terminal of the amine group-terminated prepolymer. In one embodiment, the molar ratio of alicyclic polyisocyanate to alicyclic primary polyamine may be 1:1.2 to 3, preferably 1:1.5 to 2.5, and more preferably 1:2 to 2.5. Within this range, an amine terminal prepolymer having amine groups at both ends of the prepolymer can be effectively prepared.

On the other hand, the alicyclic polyisocyanate is a polyisocyanate containing an alicyclic group, that is, a cycloalkylene group, specifically, for example, isophorone diisocyanate (IPDI), 4,4'-dicyclohexylmethane diisocyanate (hydrogenated MDI ), selected from the group consisting of cyclohexylene diisocyanate, methylcyclohexylene diisocyanate (hydrogenated TDI) and bis(2-isocyanatoethyl)-4-dicyclohexene-1,2-dicarboxylate, etc. It may be any one or two or more, preferably isophorone diisocyanate (IPDI) is used.

The alicyclic primary polyamine is any one selected from the group consisting of isophorone diamine (IPDA), N-aminoethyl piperazine, bis(P-aminocyclohexyl)methane, and 1,3-bis(aminomethyl)cyclohexane. It may be one or two or more, and isophorone diamine (IPDA) is preferably used.

Such an amine group-terminated prepolymer may be added at 10 to 30% by weight, more preferably at 13 to 20% by weight, based on the total weight of the main material. In this range, a road surface coating film can be easily formed and can have super-fast curing properties.

In one example of the present invention, the polyaspartic acid ester undergoes a cross linking reaction with the alicyclic polyisocyanate to form a three-dimensional network structure, thereby increasing the adhesion of the road surface coating film to asphalt or concrete It is added to improve the mechanical properties of the overcoating film, and specifically, for example, the polyaspartic acid ester may satisfy Formula 1 below.

[Formula 1]

(In Formula 1, X is a divalent alicyclic group, and R ₁ to R ₄ are each independently an alkyl group having 1 to 10 carbon atoms, a cycloalkyl group having 5 to 30 carbon atoms, or an aryl group having 6 to 30 carbon atoms.)

By adding a polyaspartic acid ester that satisfies this to the paint composition, the mechanical properties of the road-covering coating film can be effectively improved. Such a polyaspartic acid ester may be added at 15 to 40% by weight, more preferably at 20 to 35% by weight, based on the total weight of the main material. In this range, the effect of improving mechanical strength is excellent.

In one example of the present invention, the surface-modified zeolite is added to improve the stability of the paint composition against water, and in particular, it can be mixed well and uniformly in the subject by using the surface-modified zeolite. As a preferred example, the surface-modified zeolite may be one obtained by modifying the surface of the zeolite with ureido-based silane. In this way, by modifying the surface of the zeolite with a ureido-based silane having a urea structure, which is a chemical structure similar to that of the amine-terminated prepolymer, which is the subject, not only the miscibility of the prepolymer can be further increased, but also when the subject and the curing agent are mixed, when forming an ultra-fast-curing road surface coating film By extending the gelation time of the paint, the workability of the paint can be improved, and the durability and wear resistance of the paint film can be improved by participating in the reaction.

As a specific example, the ureido-based silane may satisfy Formula 2 below, and more specifically, for example, the ureido-based silane may be 3-ureidopropyltrimethoxysilane, 3-ureidopropyltriethoxysilane, or It may be a mixture of these.

[Formula 2]

(In Formula 2, L is an alkylene group having 1 to 10 carbon atoms, and R ₁₁ to R ₃₃ are each independently an alkyl group having 1 to 6 carbon atoms.)

In addition, the zeolite may be zeolite A, and the pore size may be 0.3 to 0.5 nm, and the average size may be 1 to 5 mm. Also, the bulk density may be 700 to 850 g/L.

Such a surface-modified zeolite may be added in an amount of 0.5 to 5% by weight, more preferably 1 to 3% by weight, based on the total weight of the main material. Within this range, it is possible to improve the workability of the paint and effectively improve the durability and abrasion resistance of the paint film.

In addition to this, the main agent may further include an amine group-containing silane. Amine group-containing silane is added to improve the adhesive strength to the road surface such as concrete and asphalt and to more firmly fix the glass beads, specifically, for example, 3-aminopropyl trimethoxysilane, 3-aminopropyl Triethoxysilane, 3-aminopropyl methyldimethoxysilane, 3-aminopropyl methyldiethoxysilane, N-2-(aminoethyl)-3-aminopropyl trimethoxysilane, N-2-(aminoethyl)- Selected from the group consisting of 3-aminopropyl triethoxysilane, N-2-(aminoethyl)-3-aminopropyl methyldimethoxysilane and N-2-(aminoethyl)-3-aminopropyl methyldiethoxysilane, etc. It may be any one or two or more, and it is preferable to use 3-aminopropyl triethoxysilane.

Such an amine group-containing silane may be added at 0.1 to 3% by weight, more preferably at 0.3 to 1% by weight, based on the total weight of the main material. Within this range, the adhesive strength to road surfaces such as concrete and asphalt can be improved, and the glass beads can be fixed more firmly.

Furthermore, the subject may further include any one or two or more selected from the group consisting of an extender pigment, a coloring pigment, an antifoaming agent, and an antisettling agent.
