The present invention relates to an environmentally friendly methyl methacrylate-based anti-slip grooving paint composition and a non-slip grooving construction method using the same, and more specifically, to allow grooving formed on a concrete or asphalt road surface to remain intact for a long time. For the non-slip paint base, unsaturated polyester resin is mixed with acrylic resin, which contains acrylic polymer and acrylic crosslinking agent, to MMA resin, thereby providing excellent adhesiveness and abrasion resistance to grooving.

In general, anti-slip paving is a facility for safe driving of vehicles by increasing the slip resistance of the pavement, and it increases the slip resistance of the pavement surface in places where the slip resistance of the road surface is low, and the plane and the terminal linearity of the road are poor. It is a facility that is installed for the purpose of preventing traffic accidents by shortening the braking distance or increasing the identification of roads where people walk such as school commuting paths and crosswalks.

The anti-skid pavement is intended to increase friction by installing in a section where the required level of sliding resistance is not secured according to the road geometry and traffic characteristics. In other words, if the sliding resistance of the pavement falls below a certain level over the entire section as the service life of the road increases, the road is repaired using an anti-slip paint composition to fundamentally increase the sliding resistance in terms of maintenance of the pavement. In recent years, such a non-slip coating composition has been increasing in demand as it is applied to the roof of the building, an outdoor parking lot, a park, etc., which is a slippery place in addition to the road.

Particularly, roads paved with asphalt or concrete have a solid and flat road surface, which gives a comfortable and good ride when driving a vehicle, while roads are very slippery when driving at high speeds or in snow or rain, such as curve roads and slope roads. There is a problem that traffic accidents occur frequently in hazardous areas.

Therefore, at present, a strip-shaped anti-slip layer formed by aggregates and binders is formed on the road surface at a predetermined interval at a height of about 3 mm to 5 mm so that friction force acts on the vehicle tire to prevent slippage. According to the current domestic road safety facility standards, the non-slip facility aggregate is a lightweight aggregate having a high coefficient of friction and excellent wear resistance, and having a Mohs hardness of 8.0 or more and a particle diameter of about 5 mm. In general, slag, silica (SiO 2), waste glass, etc., produced during the steelmaking process in steel mills are mixed with a binder and used on a road surface.

As a conventional technique related to such an anti-slip paint composition, in order to increase the sliding resistance of the road surface in Korea Patent Application No. 2007-0067846, a composition is prepared by separating the main body and the curing agent in a two-component type as the bottom resin layer, The main subject comprises 40 to 60% by weight of modified epoxy resin, 12 to 18% by weight of reactive diluent, 8 to 12% by weight of pigment, 13 to 27% by weight of filler and 3 to 7% by weight of antisettling agent; The composition is known that the composition comprising 35 to 53% by weight of modified aromatic special amine curing agent, 35 to 53% by weight of modified aliphatic amine curing agent, and 9.5 to 14.5% by weight of aliphatic tertiary amine.

In addition, Korean Patent No. 10-1022197 discloses an olefinic thermoplastic elastomer and a modified polypropylene in a resin mixed at a ratio of 80 to 20% by weight of methyl methacrylate and 20 to 80% by weight of ethyl acrylate. 25 to 45 wt% of a modified methyl methacrylate resin prepared by mixing at least one selected from 3 to 15 wt%, and adding 0.5 to 2 wt% as a curing accelerator; 30 to 45% by weight of one or more aggregates selected from the group consisting of silica sand, bauxite, steelmaking slug, walnut shell, bamboo shell, color sand, and glass beads; 15 to 30% by weight of one or more fillers selected from bentons, silica, calcium carbonate, talc, barium sulfate, and aluminum hydroxide; A functional filler comprising a mixture of charcoal and aluminosilicate powder in a ratio of 1: 1, wherein the silicate powder has a particle size of 30 to 100 μm, specific gravity of 0.7 to 0.9, and a melting point of about 1,500 to 1,900 ° C. 3 to 10% by weight of a functional filler which is a hollow powder; 2 to 5 weight percent of sieving pigments; And 1 to 2 weight percent wax are known.

However, in the case of the non-slip packaging constructed using the compositions of the patents described above, there was a durability problem such as cracking according to the properties of the MMA when the MMA was used alone, and a mixture added to supplement the properties of the MMA and the MMA. Due to problems of physical properties such as hardenability and adhesiveness due to miscibility with resin, the surface of the pavement is easily cracked due to the load and impact of heavy trucks, or the anti-slip effect is greatly reduced over time due to the weakening of adhesive force and the wear of aggregate. There was a problem.

On the other hand, the grooving method increases the sliding resistance and drainage capacity of concrete pavement or asphalt concrete pavement to prevent hydroplaning phenomenon and prevent slipping when water film is formed on the road surface. By making a groove on the road surface, also called a safety tool installation space, the horizontal groove and the longitudinal groove formed on the pavement surface by grooving work allow for smooth drainage during rainy weather, Part of the fine insert into the groove has the effect of increasing the traction and sliding friction, which is more desirable for flat tires with a heavy tread pattern wear.

This grooving method is a pavement surface treatment method first developed by NASA for aircraft safety in the 1960s, and it forms various dimensions of pavement surface by forming three-dimensional grooves on the pavement surface of airports and roads. Texturing), which is applied for anti-slip that prevents tire patterns, water film phenomenon, and anti-slip due to improved drainage, control of freezing and driving safety, and noise reduction, according to the Korea Transport Institute. Road pavement accidents have been reduced by 38% after pavement installations, and are reported to have been reduced by 20-50% in the United States.

Until now, in general, only lateral grooving has been applied to shorten the braking distance, but it has excellent effects in improving the driver's gaze guidance and visual perception of objects, reducing noise, improving driving convenience, and improving driving traction. The directional grooving method is extended to curved sections, slope sections, tunnel sections, etc., and contributes greatly to reducing traffic accidents. The lateral grooving is applied for the purpose of deceleration warning effect by shortening the providing distance, generating intentional driving noise and vibration, and in the flat section with less than 2% of the end gradient in the section with poor drainage and the cold section with frequent winter freezing accidents. Is being applied to.

The grooves on the pavement are divided into texturing and grooving depending on the width of the paving pattern. The width of the unit pattern from the center of the valley to the center of the next valley (W) The length of over 1.7mm is grooving, and smaller than that is classified as texturing.

When the grooving is classified according to the pattern, the grooving is divided into a longitudinal grooving that forms a groove parallel to the driving direction of the vehicle or an aircraft, and a transverse grooving that cuts perpendicularly to the traveling direction. Longitudinal grooves for longitudinal grooving are suitable for curves, slopes, straight roads and overpasses that are susceptible to side winds.In curves, the tire grip is increased and the steering control is stabilized during cornering. Prevent accidents.

The horizontal groove of the lateral grooving is applied to prevent drowsy driving by warning sound and vibration transmitted from the tire when driving, and to reduce the warning, and to reduce the braking distance at the entrance section of intersection, pedestrian crossing, toll station, and wet road surface in rainy weather. It is applied to the flat section of the section where the drainage is weak and where the freezing accident is frequent in winter.

Until now, in general, lateral grooving has been applied only to shorten braking distance, but curves longitudinal grooving method with excellent effects in driver's facility inducing effect and visibility, noise reduction, driving convenience, and driving traction. It is greatly contributing to the reduction of traffic accidents by extending the application to sections, slope sections and tunnel sections.

Looking at the conventional grooving construction method for preventing slipping, in the road surface forming method in which the grooving is applied to the pavement surface in Korean Patent Publication No. 10-2005-0047225, Groove formed through the grooving step BACKGROUND OF THE INVENTION There is known a dustproof coating grooving method for a road surface comprising a groove coating step of applying a coating coating to the coating. This method is to apply a resin coating to the surface where the grooves are subsequently formed in order to improve the road surface friction force after forming the grooves, and the grooves formed by the grooves by the resin applied after the grooving are formed. As the filling phenomenon occurs, it is difficult to prevent slippage and secure visibility, and the drainage effect is also reduced.

In addition, the Korean Patent No. 10-681878 is a road surface grooving method for forming a plurality of continuous grooves on the pavement surface, the road cleaning step for removing foreign matter from the road, and on the completely dried road surface with the normal road surface A paint layer forming step of applying paint having a distinctive color to the surface of the road, and cutting the continuous grooves in a direction perpendicular to the driving direction of the road where the paint layer is formed to absorb dust generated at the same time by vacuum, A series of grooves having a depth of about 4 to 5 mm, a width of about 9 mm, and an adjacent groove about 50 mm so that the depth and width of the grooves and the ratio of adjacent grooves is about 1: 2: 10. There is a known method for groove construction of a road in a child sanctuary with a series of steps.

This construction method prevents the shape of the grooved grooves from clogging as in the above example by forming a paint layer on the road surface and then forming grooves by grooves. However, the grooving structure has a structural problem that the durability of the grooving structure is weakened and the cushioning function cannot be exerted because the groove is formed at regular intervals from the surface of the road, and only the paint layer is formed on the road surface. There is a limit that can not improve the durability of the grooving structure or the anti-slip function alone.

In addition, Korean Patent Laid-Open Publication No. 10-2011-0002118 forms a primer coating layer, a resin layer, an anti-slip material layer, and a Zion pigment layer on an upper surface layer of a road, and then, by grooving, an upper surface of the road surface where the grooving is constructed. The grooving structure, characterized in that the primer coating layer, the resin layer, the anti-slip material layer, and the Zion pigment layer are formed on the surface in a layered manner, and the road surface layer is exposed on the side surfaces and the bottom surface of the grooved grooved surface. And the construction method is known, but this patent is not environmentally friendly because the epoxy resin is applied on the primer, peeling, desorption, whitening from the grooving proceeds a certain period of time, the collapse and sliding effect of the grooving structure is significantly reduced There was a problem.

Although grooving coated with a permeable water-repellent reinforcing coating composition and a construction method thereof are known, there is a water-repellent effect due to silicone resin, but also there is a limit to the collapse and sliding effect of the grooving structure due to durability problems. There was a problem.

Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

As the first aspect of the present invention, the eco-friendly methyl methacrylate anti-slip grooving paint composition of the present invention is an acrylic resin 80 of 40 to 90% by weight of methyl methacrylate (MMA) and 10 to 60% by weight of an acrylic polymer. 100 parts by weight; 0.1 to 10 parts by weight of an acrylic crosslinking agent; 80-100 parts by weight of unsaturated polyester (UPR); 3-10 parts by weight of BPO (Benzoyl Peroxide) curing agent; 3 to 10 parts by weight of a DMA (dimethyl aniline) polymerization accelerator; 1 to 3 parts by weight of γ-methacryloxypropyl trimethoxysilane coupling agent; is configured to include.

The methyl methacrylate (MMA) resin is a reactive resin made to have a double carbon bond through a polymerization process of acrylic acid and mita acrylic acid ester. MMA resin has excellent properties such as durability, heat resistance, chemical resistance, abrasion resistance, and UV safety, and has excellent weather resistance, which is resistant to weather and climate such as sunlight, to suppress corrosion due to external environmental changes (weather and climate change), At the same time, it is used to improve adhesion strength and toughness by infiltrating and integrating into the package and to improve colorability by pigments.

The methyl methacrylate (MMA) resin is a colorless transparent liquid, which is prepared by oxidizing tert-butyl alcohol (TBA) prepared by using C4 oil in a gaseous state to prepare methacrylic acid, followed by methanol. It can be prepared by esterification.

In addition, the methyl methacrylate (MMA) resin is excellent in transparency, weather resistance, colorability is used in many fields. Polymeric materials have different properties depending on the molecular weight, but methyl methacrylate (MMA) resins are hard and flexible, and syndiotactic structures that show a continuous regularity of the polymer chain structure when radically polymerized at low temperature It shows the characteristic that the ratio of increases.

Generally, acrylic resins have a high coefficient of thermal expansion, but methyl methacrylate (MMA) resins have a very high stability. Methyl methacrylate (MMA) resins are known to have the formula CH2 = C (CH3) CO2CH3.

In addition, MMA resin starts curing when a small amount of curing agent is added about 2 to 5% of the amount of resin, and is a super fast curing resin which is completely cured within 1 hour after the start of curing. Due to its excellent properties, it can be laid and finished in a large area. The MMA resin has excellent strength after curing, but not only is it lacking crack resistance and bending tracking property, but also has a different thermal expansion characteristic from the substrate. When used outdoors, there was a drawback that cracking was likely to occur. In addition, conventional MMA resin has a disadvantage in that it takes a long time and costly construction because a separate adhesive must be applied before applying to the asphalt pavement in general.

In the present invention, to solve the above problems and to improve the physical properties of the MMA resin further, by mixing and modifying a separate acrylic resin to MMA resin, an acrylic resin having excellent adhesion and excellent coating properties and surface hardening state was used. . More specifically, in the present invention, by using an acrylic resin mixed with 40 to 90% by weight of methyl methacrylate (MMA) and 10 to 60% by weight of the acrylic polymer, it is excellent in adhesion to concrete or ascon packaging, Surface hardening state showed excellent physical properties.

The methyl methacrylate (MMA) is preferably in the range of 40 to 90% by weight, the use of less than 40% by weight of the coating workability is lowered, when it exceeds 90% by weight is curable. In addition, the use of the acrylic polymer is preferably 10 to 60% by weight, when using less than 10% by weight, the curability is lowered, when it exceeds 60% by weight coating workability is lowered.

Here, the acrylic polymer is at least one acrylate selected from 30 to 80% by weight of methyl methacrylate and methyl acrylate, ethyl acrylate, n-butyl acrylate, t- butyl acrylate, 2-ethylhexyl acrylate The polymer copolymerized using 20 to 70% by weight of the monomer is used, and when the methyl methacrylate is used at less than 30% by weight, the surface hardening state is not good. It is good to use in the above range because there is cracking phenomenon.

In addition, the acrylic crosslinking agent is ethylene glycol diacrylate, ethylene glycol dimethacrylate, 1,2-propylene glycol diacrylate, 1,2-propylene glycol dimethacrylate, 1,3-butylene glycol diacrylate , 1,3-butylene glycol dimethacrylate, 1,4-butylene glycol dimethacrylate, 1,6-hexanediol diacrylate, 1,6-hexanediol dimethacrylate, diethylene glycol di Acrylate, diethylene glycol dimethacrylate, dipropylene glycol diacrylate, dipropylene glycol dimethacrylate, triethylene glycol diacrylate, triethylene glycol dimethacrylate, tetraethylene glycol diacrylate, tetraethylene Use one or more selected from glycol dimethacrylate, polyethylene glycol diacrylate, and polyethylene glycol dimethacrylate. , The amount of use thereof is 0.1 to 10 parts by weight preferred, and 0.1 parts by weight of the curable if this is lowered when used under more than 10 parts by weight, the flexibility of the coating surface after curing decreases the buffering capacity of the coating surface is reduced.

On the other hand, the unsaturated polyester (UPR) of the present invention is used as a supplementary resin of MMA resin, belongs to a thermosetting resin and necessarily contains unsaturated polyacid, and in combination with saturated polyhydric acid and polyhydric alcohol, dehydration condensation reaction A liquid resin obtained by diluting an unsaturated Alkyd Binder, which is a polymer produced in a reactive vinyl monomer, is a resin, which varies depending on quality but has a viscosity of 0.5 to 10 Pa · s, specific gravity of 1.1 to 1.5, and colorless and transparent but can be colored.

In addition, it has excellent hardenability and good moldability and workability, but at a low temperature, the viscosity is drastically reduced, which makes it almost impossible to work. The following figure shows the molecular structure of unsaturated polyester.

The most conventional unsaturated polyester resin is prepared by diluting a mixture of 55:45 with SM using Binder and reactive vinyl monomer obtained by polycondensation reaction of 1 mole of MAn, 2 mole of PAn, and 3 mole of PG. The physical properties after crosslinking and curing change depending on the type of acid, the type of glycol, and the amount of use thereof.

Unsaturated polyester resin is manufactured by heating polyesterification reaction under nitrogen supply in a heated stirring reactor equipped with a packed column, steam-jacket, and water total condenser. Generally, in the conventional type using PAn (Ortho-), one-stage reaction is performed. In the reaction time of 10-14 hours, the reaction temperature is synthesized differently depending on the required molecular weight at 150 ℃ ~ 250 ℃, when using the IPA generally reaction time 22 ~ 32 hours, 180 for the distribution of stable double bonds Unsaturated polyester binder is prepared by 2-stage reaction at ˜230 ° C., followed by dilution with reactive monomer, and is synthesized with 1.0-2.0 moles of PAn, 1.0 moles of MAn, and 2.8-2.1 moles of PG as the most common UPR. It is composed of 35 ~ 45% SM.

In the present invention, the unsaturated polyester resin has a styrene monomer content of 30 to 45% by weight, specific gravity 1.1 to 1.5 (25 ° C), viscosity 0.5 to 10 Poise (25 ° C), nonvolatile content 55 to 70% by weight, acid value 15 to 30 mgKOH / g and a gelation time of 20 to 50 minutes are used.

When the content of the styrene monomer reactive diluent is less than 30% by weight, the strength becomes strong, but cracking occurs due to shrinkage of the unsaturated polyester resin, and when the content exceeds 45% by weight, the strength decreases due to the excess diluent, and the unsaturated polyester If the viscosity is outside the range of 0.5 ~ 10 Poise (25 ℃) less than 0.5poise curing time is slow, workability is lowered due to the high viscosity of 10poise. In addition, the unsaturated polyester is less workability when the gelation time is less than 20 minutes outside the range of 20 to 50 minutes, the gelation time is longer when 50 minutes exceeds the workability also decreases.

The unsaturated polyester resin is used in the same ratio as the acrylic resin as 80 to 100 parts by weight of the total composition, but less than 80 parts by weight is degraded as a performance supplement resin, when more than 100 parts by weight is deteriorated in the physical properties of MMA Excessive use of expensive resins leads to excessive economic costs.

As a hardener, benzoyl peroxide, also called BPO, is used. BPO is the most oxidizing power among various organic peroxides, so it is easily exploded and ignited by heating, friction, impact, etc., but if it contains moisture, its risk is significantly lower. It is not easily soluble in water, but is easily soluble in organic solvents such as ether, and is mainly used as a polymerization initiator to initiate radical polymerization of vinyl units by generating phenyl radical and benzoate radical by thermal decomposition in a solvent.

In the present invention, it is used as a curing agent of acrylic resin and unsaturated polyester resin, it is preferable to use 3 to 10 parts by weight of the composition of the present invention, there is a problem that the partial curing or curing is shortened outside the above range. In addition, the BPO curing agent can be used to control the curing time by using various ratios in the composition, and also in Korea, the air temperature and surface temperature is different in each season, mixing a large amount in the winter and a small amount in the summer to control the calorific value Can be used.

Meanwhile, DMA (dimethyl aniline) polymerization accelerator plays a role in helping to generate active radicals that induce chain polymerization of methyl methacrylate (MMA) or copolymerization reaction of MMA and acrylic polymer, and at the same time unsaturated polyester (UPR) and MMA It is preferable to use 3 to 10 parts by weight in the composition of the present invention to act as a reaction catalyst with.

If less than 3 parts by weight of the DMA polymerization accelerator is used, the curing time is too late, the working time is long, and the complete curing of the surface is delayed, there is a problem of contamination, when used more than 10 parts by weight there is a problem in the storage properties of the product during storage The gelling phenomenon progresses rapidly, and relatively high self heat is generated by rapid hardening, which may cause shrinkage and color change.

In addition, the γ-methacryloxypropyltrimethoxysilane coupling agent of the present invention serves to enhance the interfacial adhesion between the MMA resin and the unsaturated polyester resin, which is an organic material, and the anti-friction friction material, which is an inorganic material. By the addition of a ring agent, the bond strength of the anti-slip friction material is significantly increased, and in the present invention, it is preferable to use 1 to 3 parts by weight of γ-methacryloxypropyltrimethoxy silane as the silane coupling agent.

In addition, the environmentally friendly methyl methacrylate-based anti-slip paint composition 5 or more heat-resistant pigments selected from alumina silica, bubble grass, pearlite, obsidian, elvan, kaolin, selenite, illite having a size of 30 ~ 100㎛ 5 It may further comprise -10 parts by weight.

The reason for adding the heat-shielding pigment is that infrared rays, which occupy half of the sunlight, are absorbed on the surface of road pavement such as ascone, tuscone, concrete, and so on, causing vibration of molecules to generate heat energy. Since the rising, and the non-slip layer of the road paving material is also heated to deteriorate and fall off the non-slip layer is to use the heat-shielding pigment for heat shielding of the sun.

As a second aspect of the present invention, the present invention comprises the steps of uniformly applying the environmentally friendly methyl methacrylate-based anti-slip grooving paint composition to the asphalt or concrete substrate grooved surface to form an undercoat layer; Forming a non-slip layer by uniformly spreading and curing a sliding friction material in which silica sand and bauxite having a particle diameter of 0.1 to 2 mm are mixed in a 1: 1 weight ratio on the undercoat layer; It provides a non-slip grooving construction method using an environmentally friendly methyl methacrylate-based anti-slip paint composition comprising a; and applying a top coat to the top of the non-slip layer.

In particular, the sliding friction material used is a mixture of silica sand and bauxite having a particle size of 0.1 ~ 2mm in a 1: 1 weight ratio, when the silica sand is used more than the ratio, the relatively low strength silica in the non-slip coating film is exposed to the surface As a result, there is a problem in that it is easily dropped by an external light impact when walking or driving a vehicle. When using less than the ratio, the amount of expensive bauxite is increased, which is not economical. In addition, if the particle size is less than the above range, since roughness is hardly generated on the surface, the required sliding resistance value cannot be obtained. On the contrary, if the particle size exceeds the above range, the surface protrudes excessively, resulting in problems such as road noise.
