Description

TECHNICAL FIELD [0001] The present invention relates to a room temperature curing type lane paint composition and a lane construction method using the same,

The present invention relates to a room temperature curing type lane paint composition and a lane construction method using the same, and is excellent in adhesion strength to be utilized for general roads, highways, landscaping spaces, walkways, parking lots, squares, bicycle roads, pedestrian roads, A lining paint composition having excellent abrasion resistance, chemical resistance and heat resistance (heat resistance performance), and a lane construction method using the same.

Generally, hot paint painting method and cold paint painting method are used depending on the place to be painted and the climatic conditions as a method of painting the lane on the road surface of the pavement. In such a coating method, a room temperature curable lane paint composition is used as a low-viscosity reactive MMA (methyl methacrylate) resin having excellent penetration to the road surface and excellent viscosity and having a viscosity of 50 to 500 mPa · s (at 20 ° C) Is mixed with one or more reactive acrylic resins and added as a main component in accordance with a required glass transition temperature, or an epoxy resin, a urethane resin, or the like is used.

According to the above-described conventional lane-painting method, the curing time at the room temperature curing is long, which hinders the passage, and it is inconvenient when the construction such as curing by applying heat is required. On the asphalt road, when the adhesion between the road surface and the paint is poor There is a problem that the coating film is peeled off or peeled off because of low durability.

In addition, when the coating is applied on the concrete road surface, the coating easily peels and peels off due to the strong alkaline release from the concrete. Especially, the alkyd resin binder which is widely used for the lane coating is formed by the strong alkaline substance coming from the concrete layer, There is a problem that the resin is denatured and durability is weakened.

Further, since the conventional lane painting method is a fusing type and the white or yellow lane is painted on the road surface with a constant width, the lane is clearly visible on the road with black road surface as in the new asphalt lane. However, according to the concrete pavement or long- There was a risk of traffic accidents because lanes, especially white lanes, were not clearly visible on the roads of gray-faded roads such as these worn asphalt roads.

In addition, the conventional room temperature curing type paint is a method of simply mixing and applying PMMA mono or unsaturated polyester resin with additives, which requires uniform mixing between the constituents, and the constituents are not maintained in a uniformly dispersed state There was a problem that stability was poor.

In addition, since solvents are used to dissolve the resin for quick drying, volatile organic compounds that are harmful to the human body are discharged due to volatilization of the solvent during operation, and therefore, the operator needs to pay attention.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments and physical property measuring methods of the room temperature curing type lane paint composition and lane construction method using the same will be described in detail. The present invention may be better understood by the following examples, which are for the purpose of illustrating the present invention and are not intended to limit the scope of protection defined by the appended claims.

The room temperature curable type lacquer composition of the present invention can provide a room temperature curable lacquered paint composition having excellent durability, adhesive performance, abrasion resistance, chemical resistance, heat resistance (heat-insulating performance), and no heavy metal harmful to human body, have.

The room-temperature curable lane paint composition of the present invention comprises S1 to S4 in which 100 parts by weight of solid core-mesoporous shell silica spheres (SCMS) (TEOS / SCMS) surface-modified with TEOS (tetraethoxysilane) , Ethyl acrylate monomer (EAM), butyl acrylate (n-butyl acrylate), and butyl acrylate (100 parts by weight) based on 100 parts by weight of a solid core-mesoporous shell silica spheres (SCMS) 2 to 4 parts by weight of an organic solvent is added to 200 to 400 parts by weight of an acrylic compound selected from at least one of acrylic acid, butylacrylate (BA), methyl methacrylate (MMA) and acrylic acid (AA) (S3) of preparing a metal oxide dispersion solution, 100 parts by weight of the acrylic composite, 30 to 45 parts by weight of an organic solvent, 30 to 45 parts by weight of a crosslinking agent, And 40 parts by weight of water.

In step S1, a solid core-mesoporous shell silica sphere (SCMS) (TEOS / SCMS) surface-reformed with TEOS (tetraethoxysilane) is prepared. In step S2, an acrylic complex is synthesized. The modified SCMS (TEOS / SCMS) is used for surface modification, and the acrylic composite has a larger surface orientation and contributes to improved dispersibility, thermal stability and durability.

In step S1, a mesopore is formed by calcining C18-TMS at 550 ° C. for 6 hours to form a solid core-mesoporous shell silica sphere. Tetraethoxysilane (TEOS) is slowly heated (TEOS / SCMS), which is surface modified with TEOS (tetraethoxysilane).

In step S2, the acrylic compound and the organic solvent are added to the reaction vessel and stirred for 40 to 60 minutes. Then, the catalyst is added, stirred for 30 to 50 minutes, then 8 to 12 parts by weight of chloroform is added, (TEOS / SCMS), which is surface-modified with TEOS (tetraethoxysilane), and stirred for 6 to 9 hours. In the step S2, the reaction tank is preferably maintained at a temperature of 50 to 70 DEG C so that stirring and polymerization reaction can be smoothly performed.

The catalyst may be exemplified by hexachloroplatinic acid (H ₂ PtCl ₆ ). The polymerization proceeds quickly to suppress the addition reaction, and the dispersed platinum acts as a photocatalyst.

The chloroform or HCHO serves to ensure the purity of the acrylic complex through washing.

If the amount of the acrylic compound is less than 200 parts by weight based on 100 parts by weight of the solid core-mesoporous shell silica spheres (SCMS) (TEOS / SCMS) surface-modified with TEOS (Tetraethoxysilane) The strength is weak or the surface is not smooth smoothly. If it exceeds 400 parts by weight, it is weakened by impact after curing.

The acrylic compound may be at least one selected from the group consisting of ethyl acrylate monomer (EAM), n-butyl acrylate (BA), and methyl methacrylate (MMA) acid, AA).

For example, 35 to 40% by weight of methyl methacrylate (MMA), 15 to 20% by weight of n-butyl methacrylate (BAM), 15 to 20% by weight of butyl acrylate (n- 15 to 20% by weight of butyl acrylate, BA), and the balance acrylic acid.

However, acrylic acid is preferably 20 to 3% by weight based on the total weight of the acrylic compound. If the acrylic acid content is less than 20% by weight, the acrylic composite may not be sufficiently synthesized, and if it exceeds 30% by weight, the physical properties may deteriorate.

In addition, the present invention may further comprise 0.1 to 10 parts by weight of polyethylene wax based on 100 parts by weight of the acrylic compound, if necessary. By using the composition in the above range, not only the storage stability of the composition is enhanced but also the wax layer is formed on the surface after application of the lane composition to prevent contact with oxygen to prevent the radical of the composition from disappearing, .

The present invention also relates to a process for the production of an acrylic resin composition, comprising the steps of: (1) optionally mixing 100 parts by weight of an acrylic compound with at least one monomer selected from the group consisting of polyvinyl butyral, acrylonitrile-styrene (AS), acrylonitrile-butadiene- (MB), methacrylic ester-butadiene-acrylonitrile-styrene (MBAS), styrene-butadiene rubber (SBR), polybutadiene rubber (BR), polyisoprene rubber (IR), chloroprene rubber 10 to 20 parts by weight of at least one viscosity modifier selected from NBR, chlorinated rubber, acrylic rubber, epichlorohydrin rubber, liquid polybutadiene, and liquid acrylonitrile-butadiene copolymer may be further added. If it is added in an amount of less than 10 parts by weight, the effect is insignificant, and if it exceeds 20 parts by weight, the viscosity increases sharply. In addition, the viscosity modifier may also serve to impart elasticity of the coating.

In the step S3, a metal oxide dispersion solution is prepared, which may be carried out in a stirring tank maintained at a temperature of 60 to 80 ° C.

The metal oxide dispersion solution may be obtained by thoroughly stirring 3 to 5 parts by weight of a dispersant, 30 to 40 parts by weight of a metal oxide having an average particle diameter of 5 to 80 nm, and 55 to 65 parts by weight of an organic solvent.

The dispersant may be selected from the group consisting of polyethylene wax, 5-methoxy pentyloxy acetic acid, 3,6,9-trioxadecane acid, palmitic acid ), Stearic acid, and sodium polyacrylate may be selected.

The metal oxide may be antimony tin oxide (ATO) or titanium oxide (TiO 2). It exerts a mining power and can decompose noxious gas through photocatalytic action even in a very small ultraviolet ray.

In the step S4, the acrylic composite, the organic solvent, the cross-linking agent, and the metal oxide dispersion solution are mixed to produce a coating.

The organic solvent may be at least one selected from the group consisting of methanol purified with sodium, methylene chloride, isopropyl glycol, methyl ethyl ketone, and dimethylformamide.

The organic solvent is preferably 30 to 45 parts by weight based on 100 parts by weight of the acrylic complex. When the amount of the organic solvent is less than 30 parts by weight, dissolution of the acrylic complex is not sufficiently carried out and the viscosity is too high to lower the workability. When the amount of the organic solvent is more than 45 parts by weight, viscosity is low, And the surface hardening state may become poor.

The coupling agent may be selected from the group consisting of ethylene glycol diacrylate, ethylene glycol dimethacrylate, diethylene glycol diacrylate, diethylene glycol dimethacrylate, dipropylene glycol diacrylate, dipropylene glycol dimethacrylate, But are not limited to, triethylene glycol diacrylate, triethylene glycol dimethacrylate, tetraethylene glycol diacrylate, tetraethylene glycol dimethacrylate, polyethylene glycol diacrylate, polyethylene glycol dimethacrylate, pentaerythritol dimethacrylate And at least one of pentaerythritol tetramethacrylate and pentaerythritol trimethacrylate can be selected.

The crosslinking agent is preferably 30 to 45 parts by weight based on 100 parts by weight of the acrylic composite. When the amount of the crosslinking agent is less than 30 parts by weight, the curability is lowered. When the amount is more than 45 parts by weight, the flexibility of the coated surface is lowered after curing.

Since the metal oxide dispersion solution is prepared in a liquid phase, it is mixed or dispersed well with the acrylic complex. When the amount of the metal oxide dispersion solution is less than 10 parts by weight, the above-mentioned heat-reducing effect is not sufficiently expected. When the amount of the metal oxide dispersion solution is more than 40 parts by weight, The hardness is increased, and the adhesive force with the road surface may be lowered.

In addition, the present invention can further include a phosphoric acid ester compound and can improve the adhesion of the paint, and examples thereof include monomethyl phosphate, dimethyl phosphate, ethyl phosphate, and diethyl phosphate. The phosphoric ester compound is preferably used in an amount of 1 to 10 parts by weight based on 100 parts by weight of the acrylic composite. When the amount of the phosphoric ester compound is less than 1 part by weight, the effect is insignificant. When the amount is more than 10 parts by weight, The durability may be deteriorated.

In the step S4, the reaction vessel is preferably maintained at a temperature of 90 to 100 DEG C for 40 minutes to 1 hour so that stirring and polymerization reaction can be smoothly performed.

Meanwhile, in step S4, a reaction accelerator may be added together with the crosslinking agent, and the curing time may be controlled through the reaction accelerator. The reaction accelerator may be an accelerator, dimethyl paratoluidine, dimethylaniline, di It is preferable to use at least one member selected from the group consisting of N, N-di (2-heptyl) aniline, ethylmethaniline, ethylmethltoluidine, pyridine, phenylmorpholine, piperidine, diethanol aniline, N-dimethyl-p-toluidine, N-ethyl-N-hydroxyethylaniline, N, N-dimethyl aniline and the like, Or mixed. It is preferable that the content is 0.1 to 3 parts by weight based on 100 parts by weight of the acrylic composite. When the amount is less than 0.1 parts by weight, the curing rate is slowed. When the amount is more than 3 parts by weight, The surface is easily broken because it is discarded. If necessary, known anti-settling agents, antioxidants, ultraviolet absorbers, antifoaming agents, dispersing agents, color separation preventing agents, hardness-imparting agents and the like can be used.

The coating material prepared through steps S 1 to S 4 has strong adhesion to asphalt or concrete road surface, and is excellent in water resistance, alkali resistance and heat resistance performance, and is not easily separated from the concrete layer due to a strong alkaline substance eluted from the concrete layer during long- As well as preventing the strong alkaline effluent from contacting the lacquer coating paint, and fast curing at room temperature is possible, thereby shortening the lane coating time.

That is, the lane-setting method using the room-temperature-curable type lacquer composition of the present invention comprises the steps of preparing the room-temperature curable type lacquer composition as described above and 0.1 to 10 parts by weight of the pigment in 100 parts by weight of the room- A step B for applying a room temperature curable type lacquering composition mixed with a pigment in the step B to the road, and a step D for curing the room temperature curable type lacquer composition applied to the road.

Here, the pigment may be an organic pigment, an inorganic pigment (titanium oxide, zinc oxide, zirconium oxide, calcium oxide, barium sulfate, alumina, kaolin clay, carbon black, iron oxide and the like), a fluorescent pigment, a phosphorescent pigment, Chromate, and the like).

Also, the road marking can be easily performed by applying the room temperature curable type lane paint composition at the stages C and D by using a spray gun or the like, and lane painting can be performed by coating the road at a thin thickness of 0.1 to 5 mm and curing, Curing is possible within 30 minutes at room temperature even if there is no separate thermal curing device.

On the other hand, a lane-keeping method using a room-temperature-curable type lane paint composition includes applying a primer on a concrete pavement surface or an ascon pavement surface, spraying a paint on the pavement surface, spraying beads on the paint And curing the coating material.
The coating material is a two-component coating material comprising a room temperature curing type lacquer coating composition, which is a subject containing a reaction promoter, and an initiator (BPO); A three-component type coating material comprising a room temperature curing type lane coating composition which is a subject not containing a reaction promoter and a room temperature curing type lane coating composition which is a subject containing a reaction promoter and an initiator (BPO); (BPO) and a pigment.
