Description

Porous mineral anti-freezing material containing chloride and organic acid salts, and the anti-freezing composition and the anti-freezing pavement material containing the same pavement material including the same}

The present invention relates to a porous mineral anti-icing material containing chloride and organic acid salts, an anti-icing material composition containing the same, and a road surface anti-icing packaging material containing the same. More specifically, it relates to porous basalt particles, porous feldspar particles, and porous silica particles. At least one type selected from calcium chloride (CaCl ₂ ), sodium chloride (NaCl) or magnesium chloride (MgCl ₂ ) is placed on the porous inner and outer surfaces of one or more types of porous mineral particles selected from light particles, porous vermiculite particles or porous bentonite particles. chloride; Potassium Acetate, Calcium Acetate, Sodium Acetate, Calcium Magnesium Acetate (CMA), Calcium Formate, Sodium Formate, Potassium Citrate Citrate or sodium citrate; is filled and coated with the chloride and the organic acid salt, and the chloride and organic acid salt are eluted in a sustained manner from the inner and outer surfaces of the pores, thereby exhibiting a continuous snowmelting and melting effect, thereby producing a melting effect during the winter. It relates to a porous mineral anti-icing material containing chloride and organic acid salts that can prevent snow, rain, or black ice from freezing on the road surface, an anti-icing material composition containing the same, and an anti-icing packaging material containing the same.

In general, in the winter, the driving environment changes due to temperature drops such as road surface freezing, snow, ice, and black ice, and the traffic accident rate is higher than other seasons due to factors such as poor steering and brake operation.

In particular, black ice, which occurs during the winter, is a thin sheet of ice that forms on the road surface. Snow, frost, moisture, etc. freeze on the road surface due to a drop in temperature, forming an ice sheet, drastically reducing the friction between tires and the road surface. Not only does it cause a serious risk to the driver's driving safety by making it difficult to operate the steering wheel and lengthening the braking distance, which can lead to a major accident, but also the driver cannot perceive black ice at all, and the road simply retains moisture. It is especially dangerous because it is perceived by drivers as if it is wet.

In order to prevent the occurrence of snow, road surface freezing, and road ice (black ice) as mentioned above, in Korea, a certain amount of snow removal agent is sprayed on the road surface in advance when snowfall and temperature drops are expected (automatic salt water spray equipment is in operation for areas with frequent icing). The purpose of this is to prevent the road pavement from freezing and forming ice due to a drop in temperature during snowfall, thus securing the skid resistance and braking distance of vehicle tires and ensuring driving safety of vehicles.

Representative examples of the snow removers currently used in Korea are calcium chloride (CaCl ₂ ), sodium chloride (NaCl), and magnesium chloride (MgCl ₂ ), which are inexpensive.

The calcium chloride (CaCl ₂ ), sodium chloride (NaCl), and magnesium chloride (MgCl ₂ ) not only have the function of melting snow and ice, but also prevent or suppress melted snow/water from freezing on the road surface. They have excellent melting performance and are inexpensive. Although it is a low-toxic substance used as an inexpensive chloride-based snow remover, the use of these chloride-based snow removers is causing serious environmental problems such as corrosion of vehicles or road facilities, road cracks and damage, penetration of chloride aqueous solution into the ground, and inhibition of plant growth.

In addition, while the chloride-based snow remover has excellent initial melting performance, as time passes after spraying, the concentration of the chloride aqueous solution generated by rapidly melting snow and ice gradually becomes diluted, causing a re-freezing phenomenon in which the aqueous solution freezes again. This has the disadvantage of rapidly deteriorating melting performance.

Meanwhile, in Korea, the eco-friendly snow removal agent certification system (EL.610) has been created since 2008 and local governments are actively encouraging the use of eco-friendly snow removal agents, and eco-friendly anti-icing filler (AIF) is being developed. There are limits to the use of eco-friendly snow removers because they have poor melting performance and are expensive compared to existing chloride-based snow removers.

On the other hand, overseas in Russia, Grikol, an anti-icing material for asphalt mixtures made of 80% sodium chloride, 10% calcium chloride, and 10% Siakor (silicon-based) was developed in the 1980s and is being applied in the field. Siakor is a silicone-based hydrophobic material. ) and a non-toxic silicon-organic compound in powder form with a freezing point of -50℃, Grikol has an anti-icing effect at temperatures ranging from 0℃ to -6℃, and can be used to manufacture asphalt mixtures as a replacement for part of the filler. It is recommended to use 3 to 5% of the weight of the asphalt mixture. According to a study by Grinevitch (1998), compared to sodium chloride for snow removal, Grikol has significantly less effect on metal corrosion, and metal corrosion is reduced by 2.8 to 3.0 times. As a result of the test construction of the asphalt mixture using Grikol, it was reported that there was a 70% reduction in snow removal work at Vagverkets road station located in Taby, Sweden.

In addition, Mafilon is an anti-icing agent developed by Mannesmann Wandel AG in Germany for the purpose of preventing road surfaces from icing in the winter. It is effective at temperatures of -3 to -5℃, and passes 75 to 90% of the substances through a 0.08 mm sieve. It is a powder made by adsorbing calcium chloride or sodium chloride, which are active ingredients with anti-freezing effects, into porous igneous rock aggregate (powder).

Sang Luo et al. (2015) evaluated the snowmelt/deicing characteristics by using a high-strength asphalt binder in the general asphalt mixture mix and manufacturing an anti-icing asphalt mixture by replacing 70% of the filler with Mafilon. It was said that the mixture using high-strength asphalt and Mafilon (HEA-MFL) had improved joint performance and snowmelt/deicing performance compared to the general mixture and SBS modified mixture.

Zhou et al. (2019) conducted a short-term/long-term performance evaluation study of asphalt mixtures containing Mafilon and recommended 70% of the filler as the maximum percentage of Mafilon replacement. As the Mafilon content increases, strength properties, moisture sensitivity, and low temperature are improved. It was reported that chloride precipitation causes short-term and long-term deterioration of the anti-icing mixture, causing a decrease in durability, and that increasing the amount of Mafilon mixed shows excellent anti-icing and ice-making effects.

In addition, Verglimit is an anti-icing material composed of calcium chloride as the main ingredient and a small amount of sodium hydroxide. 5% of the total weight of the mixture is used when manufacturing the mixture. The particle size is 0.1 to 0.5 mm and was developed in Switzerland in the 1970s. It is applied in the United States, Canada, France, Japan, and the United Kingdom.

In addition, WinterPave® is an anti-freeze additive made of organic and inorganic ingredients containing chloride that lowers the freezing point of water and inhibits the adhesion of ice to road surfaces. It is used at 4 to 5% of the aggregate content when producing asphalt mixtures. It is an anti-icing packaging material manufactured by manufacturing a mixture using the plant mix method and placed on site. WinterPave® anti-icing packaging prevents the formation of ice crystals on the pavement surface, and as a result, the ice structure becomes very brittle and does not adhere to the pavement surface. Ice and snow have the advantage of being easily removed from the pavement surface during snow removal and de-icing operations using snow removal equipment.

However, the anti-icing materials used overseas had the problem of not being able to fundamentally solve the non-woven or environmental pollution problems caused by the use of chloride.

An anti-icing surface treatment composition is known, characterized in that it contains 10% by weight, 0.01 to 10% by weight of aqueous silica sol, and 0.01 to 10% by weight of alkoxy silane.

However, the above anti-icing materials are still mixed with chlorides such as calcium chloride and sodium chloride, and various fillers, binders, modified mixtures or silanes are additionally mixed, but problems of corrosion and environmental pollution due to chloride still occur. There is a problem that the anti-icing effect disappears when chloride is lost, so there is a problem that surface treatment has to be repeated.

Meanwhile, an eco-friendly snow removal agent is being developed to solve the problems of the above-mentioned chloride-based anti-icing agent. In Korea Patent Publication No. 10-2020-0106324 (published on September 14, 2020), one or more types of calcium chloride and salt are used. It includes chloride and a liquid additive, wherein the liquid additive is a mixture of a melting aid and a corrosion inhibitor, the melting aid is an aqueous organic acid salt solution, and the corrosion inhibitor is sodium phosphate, sodium citrate, or a mixture thereof. An eco-friendly snow removal agent with an enhanced re-freezing prevention function is known.

In addition, according to Korean Patent No. 10-2129062 (registration date June 25, 2020), 0.01 to 2.5% by weight of molasses, 0.01 to 2.5% by weight of glycerin, 0.1 to 4.5% by weight of organic acid salt, and 0.05 to 3.0% by weight of phosphate were mixed. Step 1: Preparing the dust abatement composition; Step 2 of preparing a mixture by mixing 50 to 85% by weight of sodium chloride, 10 to 45% by weight of magnesium chloride, and 0.01 to 2.0% by weight of red clay; Step 3 of coating the surface by adding the mixture prepared in Step 2 to the mixture prepared in Step 1 in a rotating mixer; There is a known method of manufacturing a dust-reducing, eco-friendly solid snow remover that includes the step of further adding a corrosion inhibitor and a biodegradability enhancer after the third step.

In addition, Korean Patent No. 10-2218237 (registration date: February 16, 2021) discloses magnesium chloride (MgCl2), calcium chloride (CaCl2), and salt (NaCl) as anti-icing agents for preventing or melting ice on roads. ), anti-corrosion substances, hazardous substance decomposition substances, shell powder, and photoluminescence materials, each of the magnesium chloride, calcium chloride, salt, corrosion inhibitory substances, hazardous substance decomposition substances, and shell powder An eco-friendly anti-icing agent has been developed, which is formed in granules and the photoluminescence material is coated with the salt or shell powder.

In addition, Korean Patent No. 10-2289637 (registration date August 9, 2021) includes magnesium chloride hexahydrate (MgCl2.6H2O), sodium chloride (NaCl), anti-corrosion substances, hazardous decomposition substances, and shell powder, Each of the magnesium chloride hexahydrate (MgCl2.6H2O), sodium chloride (NaCl), anti-corrosion material, hazardous material decomposition material, and shell powder is in the form of granules, and the hazardous material decomposition material is acetic acid or fumaric acid. (fumaric acid), the magnesium chloride hexahydrate (MgCl2.6H2O) is magnesium chloride hexahydrate with a purity of 46% or more, and the magnesium chloride hexahydrate (MgCl2.6H2O), sodium chloride (NaCl), corrosion The anti-corrosion substances, hazardous substance decomposition substances, and shell powder are respectively 40% to 45% by weight of magnesium chloride hexahydrate, 45% to 49% by weight of sodium chloride, 4% to 8% by weight of corrosion inhibitors, and hazardous substance decomposition substances. An organic acid-based solid snow remover has been developed, characterized by a composition ratio of 1% to 3% by weight and 0.1% to 1% by weight of shell powder.

However, the above-described eco-friendly snow removers still use chlorides such as calcium chloride and sodium chloride as they are, and use additional mixtures of harmful decomposition substances such as corrosion inhibitors and organic acids to improve the corrosion characteristics of chlorides and environmental pollution problems. , there was a problem that the anti-icing effect disappeared when chloride disappeared, so there was a problem that surface application treatment had to be repeated.

In particular, the chlorides react with moisture and dissolve easily, so long-term anti-freezing performance is reduced, and chloride ions (Cl-), which make up anti-freeze materials, cause problems such as corrosion, soil, water quality, and vegetation environment, so chloride release is prohibited. An anti-icing material is required that has the ability to prevent corrosion and environmental pollution, secure anti-icing performance, and further maintain the long-term durability of the anti-icing mixture while being properly maintained.

Accordingly, recently, a snow removal agent that can slowly release chloride and continuously exhibit snow removal performance has been developed. Korean registered patent 10-2141869 (registration date July 31, 2020) contains 60 to 90% by weight of sodium chloride; 3-30% by weight of calcium chloride; A carrier that captures the sodium chloride and the calcium chloride; and a surface treatment agent for water-repellent treatment of the collected surface; Including, the carrier includes 1 to 10% by weight, the carrier includes a clayey material, the clayey material includes bentonite and attapulgite, and the surface treatment agent includes a fluororesin, It further contains 1% by weight of a functional additive, and the functional additive is 2 to 3 parts by weight of polyalkyl acrylate, 2 to 3 parts by weight of ethylene-acrylic acid, 2 to 3 parts by weight of tetrafluoroethylene, and polyethylene, based on 10 parts by weight of acrylic urethane. A snow removal composition comprising 1 to 2 parts by weight of oxide, 0.1 to 1 part by weight of vinyltrimethoxysilane, and 0.1 to 1 part by weight of titanium dioxide has been developed.

In addition, Korea Patent No. 10-2600400 (registration date: November 6, 2023) contains 0.1 to 20% by weight of minerals; 50 to 99.7% by weight of chlorides, including sodium chloride and polyhydric chlorides; 0.1 to 10% by weight of a sealant containing at least one of a silica metal salt and a silane compound; and 0.1 to 20% by weight of water; wherein the mineral includes attapulgite, the attapulgite is dispersed by stirring with the water and the chloride, and the dispersed attapulgite is formed into a lattice by charging. to form a film, the ratio of the sodium chloride to the polyvalent chloride is 99:1 to 51:49 by weight, and the silica metal salt is selected from among silicate metal salts, sodium siliconate, potassium siliconate, and lithium siliconate. Containing one or more, the silicate metal salt includes one or more of sodium silicate, potassium silicate, magnesium silicate, and lithium silicate, and the silane compound includes alkylalkoxysilane, hydroxypropyltrimethoxysilane, hydroxide An anti-icing material composition has been developed that includes one or more of oxypropyl ethyl silane and n-octyl triethoxy silane, and the polyhydric chloride includes calcium chloride.

However, the snow remover that slowly releases chloride can still exhibit snow removal performance by slowly releasing chloride by coating it with a water repellent such as a silane compound while still using chlorides such as calcium chloride and sodium chloride. There are still problems in that it is not eco-friendly as it causes corrosion and environmental pollution problems.

1 is a schematic diagram showing porous mineral particles used in the present invention.

Hereinafter, the present invention will be described in detail through examples and/or drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments and/or drawings described herein.

First, the porous mineral anti-icing material containing chloride and organic acid salt of the present invention is a porous mineral particle selected from porous basalt particles, porous feldspar particles, porous illite particles, porous vermiculite particles, or porous bentonite particles. and on the outer surface, at least one chloride selected from calcium chloride (CaCl ₂ ), sodium chloride (NaCl), or magnesium chloride (MgCl ₂ ); Potassium Acetate, Calcium Acetate, Sodium Acetate, Calcium Magnesium Acetate (CMA), Calcium Formate, Sodium Formate, Potassium Citrate Citrate or sodium citrate; is filled and coated with the chloride and the organic acid salt, and the chloride and organic acid salt are eluted in a sustained manner from the inner and outer surfaces of the pores, thereby exhibiting a continuous snowmelting and melting effect, thereby producing a melting effect during the winter. It is designed to prevent snow, rain, freezing, or black ice on the road surface.

In the present invention, the porous mineral particles act as a carrier and a filler mixed with the chloride and organic acid salt.

That is, the porous mineral particles are porous particles with pores formed on the outside and inside, as shown in [Figure 1], and are selected from porous basalt particles, porous feldspar particles, porous illite particles, porous vermiculite particles, or porous bentonite particles. At this time, the porous mineral particles are pulverized to a particle size of 0.1 to 1 mm and heated at 500 to 600 ° C for 20 to 30 minutes to remove organic substances remaining in the pores.

The porous basalt is a type of volcanic rock, and in most cases, it is a type of rock created when lava flow erupted during a volcanic eruption cools near the surface. It is distinguished from granite that hardened deep underground. It mainly contains minerals such as olivine, dilute, plagioclase, and magnetite. It consists of a composition.

These basalts contain different chemical components depending on the region and time of formation. SiO ₂ is the main component, followed by Al ₂ O ₃ , Fe ₂ O ₃ , MgO, CaO, Na ₂ O, TiO ₂ , K ₂ O, and P ₂ O. It has component characteristics that include oxides such _as Since it is a rock that has the functions of absorption, absorption, and filtering, and is expected to have insulation performance due to pores, the porosity of basalt is utilized in the present invention.

In addition, the porous feldspar is the most common natural material among the materials constituting the earth's crust and is used as an industrial mineral to manufacture glass, paint, etc. The mineral structure of these feldspars is primarily related to the arrangement-disorganization of Al and Si, twins, soft crystals, and their complex structures (Parsons, 1994; Smith & Brown, 1988; Deer et al., 2001), and secondarily to weathering. It is divided into fine structure and deterioration.

In particular, during the weathering process, fine pores characteristically develop on the surface of feldspar. Due to the porous structure of feldspar, the specific surface area increases, the volume characteristics decrease, and the surface characteristics increase, resulting in electrical/magnetic and optical properties. Since this is known to occur (Park & Lee, 2000), the present invention utilizes the fine pores of porous feldspar.

In addition, the porous vermiculite is a monoclinic mineral with a crystal structure similar to mica, and is easily decomposed by acid and has a high cation exchange capacity. It is produced in serpentine areas. It is porous and has a good absorption capacity, so it is widely used as a heat-resistant material and soundproofing material.

In addition, the porous illite is a mica group mineral belonging to the monoclinic system. Structurally, it has a developed pore structure and has an excellent effect in coagulating red tide organisms. It adsorbs suspended substances in water and has an anion, so it can form cationic suspended particulates and It cleans water by causing coagulation and precipitation through electrical neutralization. It can adsorb and decompose 70-100% of harmful heavy metals such as lead, cadmium, and mercury, and is a useful mineral that adsorbs and decomposes organic and toxic substances. A large quantity is buried in Yeongdong.

In addition, the porous bentonite is a silicate mineral and is a porous silica clay mineral similar to silica gel or zeolite and has excellent hygroscopicity. In Korea, many of them are excavated in Pohang, a region of the Quaternary geological zone of the Cenozoic Era. It has superior hygroscopicity and is more economical than silica gel or zeolite, so it is widely used as a large-scale industrial absorbent and desiccant. It can absorb several times its weight in atmospheric water, and even if it absorbs a large amount of moisture, it does not stick like mud and maintains a sandy appearance, making it easy to handle. The price is very cheap and can be easily obtained in 10-20 kg bags.

Using the porous mineral particles as described above, the present invention fills and coats the inner and outer surfaces of the pores of the porous mineral particles with chloride and organic acid salts, so that the chloride and organic acid salts elute in a sustained manner, thereby exhibiting continuous anti-freezing performance. The characteristic is that it allows

That is, the porous mineral anti-icing material containing chloride and organic acid salt of the present invention contains calcium chloride (CaCl ₂ ), sodium chloride (NaCl), or magnesium chloride (MgCl _{2 )} on the inner and outer surfaces of porous mineral particles with a particle size of 0.1 to 1 mm. ) at least one chloride selected from; Potassium Acetate, Calcium Acetate, Sodium Acetate, Calcium Magnesium Acetate (CMA), Calcium Formate, Sodium Formate, Potassium Citrate Citrate) or at least one organic acid salt selected from sodium citrate; is filled and coated.

At this time, the porous mineral anti-icing material containing chloride and organic acid salt is a supersaturated aqueous solution in which porous mineral particles with a particle size of 0.1 to 1 mm and calcium chloride (CaCl ₂ ) and sodium chloride (NaCl) are mixed in a weight ratio of 1:0.5 to 1. is sprayed to impregnate the inside of the pores of the porous mineral particles and coat the outer surface, then homogeneously mix and dry, and then spray the aqueous solution of the organic acid salt on the dried porous mineral particles to impregnate the inside of the pores of the porous mineral particles and coat the outer surface. After coating, it is homogeneously mixed and dried to prepare the chloride and organic acid salt by impregnating and filling the inside of the pores of the porous mineral particles and coating the outer surface.

Meanwhile, a porous mineral anti-icing material containing the chloride and organic acid salt; At least one chloride powder selected from calcium chloride (CaCl ₂ ), sodium chloride (NaCl), or magnesium chloride (MgCl ₂ ); Potassium Acetate, Calcium Acetate, Sodium Acetate, Calcium Magnesium Acetate (CMA), Calcium Formate, Sodium Formate, Potassium Citrate An anti-icing material composition can be prepared by mixing at least one organic acid salt powder selected from citrate or sodium citrate.

At this time, the anti-icing material composition is preferably a mixture of porous mineral anti-icing material containing the chloride and organic acid salt: chloride powder: organic acid salt powder in a weight ratio of 1:0.5 to 1:0.2 to 0.5, and the chloride powder is Calcium chloride (CaCl ₂ ) and sodium chloride (NaCl) are preferably mixed in a weight ratio of 1:0.5 to 1, and magnesium chloride (MgCl ₂ ) can optionally be additionally mixed.

Here, the at least one chloride selected from calcium chloride (CaCl ₂ ), sodium chloride (NaCl), or magnesium chloride (MgCl ₂ ) typically exhibits anti-freezing performance by strengthening the freezing point.

That is, the calcium chloride (CaCl ₂ ) has a strong deliquescent property of absorbing moisture in the air, and has a very low common point, thereby lowering the freezing point of water. And because it undergoes an exothermic reaction when dissolved in water, it has the characteristic of melting snow and ice well at low temperatures. When calcium chloride is sprinkled on a road surface covered with snow and ice, the calcium chloride absorbs surrounding moisture and begins to melt. During the melting process, it generates heat. The heat generation promotes melting, so a larger amount of snow and ice is melted and dissolved. In addition, the freezing point of the molten aqueous solution is lowered to a maximum of -51°C or lower, thereby demonstrating excellent melting performance.

In addition, sodium chloride (NaCl) dissolves in water and lowers the freezing point to -21°C, thereby serving as a melting agent that melts snow and prevents freezing for a long time. And since sodium chloride is more efficient than calcium chloride because its saturated solubility is about 15 times that of calcium chloride, the calcium chloride and sodium chloride can be mixed and used in the present invention.

In addition, the magnesium chloride (MgCl ₂ ) can be used together with sodium chloride to provide a snow removal function, and performs the function of preventing re-freezing by lowering the freezing point. Magnesium chloride has a freezing point lowering effect similar to calcium chloride. In addition, when using magnesium chloride, it has excellent initial snow removal ability and is used for the initial snow removal reaction. It emits lower dissolution heat than calcium chloride, so it can prevent cracks in the road due to dissolution heat, but due to the high hygroscopicity of magnesium chloride, it is used for initial snow removal reaction. Since there is a problem that solidification of all chlorides may occur, the amount of use may be limited.

Meanwhile, the potassium acetate, calcium acetate, sodium acetate, calcium magnesium acetate (CMA), calcium formate, sodium formate, citric acid. One or more organic acid salts selected from potassium citrate or sodium citrate are used to prevent refreezing.

That is, after the organic acid salt is dissociated in water, the dissociated organic acid anion has the effect of delaying the tendency of water molecules to change into a crystalline structure and become ice, and the metal cation changes the direction of the water dipole. Since the organic acid salt is dissolved and dissociated in water melted by the chloride, refreezing due to the freezing point lowering effect is prevented.

In addition, the organic acid salt performs the function of preventing corrosion caused by chloride ions of the chloride and can prevent corrosion caused by chloride ions of the chloride system remaining on the road.

That is, the chloride dissolves in the eyes and decomposes into metal ions and chlorine ions, and the chlorine ions generated at this time combine with the metal to form metal chloride, causing corrosion of the metal. At this time, the organic acid salt dissociates in water. Organic acid anions oxidize the metal surface to form a metal oxide film, preventing chlorine ions from coming into direct contact with the metal, thus suppressing corrosion.

On the other hand, with respect to 100 parts by weight of the anti-icing material composition, sodium tertiary phosphate (Na3PO4), disodium hydrogen phosphate (Na ₂ HPO ₄ ), and sodium hexameta phosphate (sodium hexameta phosphate; (NaPO ₃ ) ₆ ] and may further contain 1 to 10 parts by weight of one or more phosphates selected from the group consisting of.

The phosphate is used to prevent the metal from being corroded by the chloride. The hydrogen phosphate ions generated when sodium phosphate is dissolved in water form a passive film on the metal surface, which prevents the metal from being corroded by the chloride. is prevented.

In other words, the chloride reacts with chlorine ions (Cl ^- ) and iron (Fe) to rapidly form iron chloride (FeCl ₂ ), which corrodes not only iron but also concrete and asphalt at a very high rate, causing damage to cars, bridges, and all road facilities. Because the lifespan is shortened, hydrogen phosphate ions generated when the sodium phosphate is dissolved in water form an oxide film on the metal surface to prevent corrosion.

In addition, 1 to 10 parts by weight of calcium oxide may be further included based on 100 parts by weight of the anti-icing material composition.

The calcium oxide has the chemical formula CaO, and absorbs moisture and carbon dioxide in melting ice, decomposing into calcium hydroxide (slaked lime) and calcium carbonate, and generates heat, thereby producing snow melting and melting effects. In addition, the calcium hydroxide (slaked lime) and calcium carbonate produced at this time are asphalt. Alternatively, it can be filled into cracks or voids in cement concrete to provide a road surface reinforcement effect.

Meanwhile, the present invention includes 5 to 30 wt% of low viscosity methyl methacrylate resin (MMA) with a viscosity of 5 to 1,000 cps, and 20 to 50 wt% of medium viscosity methyl methacrylate resin (MMA) with a viscosity of 3,000 to 8,000 cps. , 100 parts by weight of a base material containing 20 to 75% by weight of a high viscosity methyl methacrylate resin with a viscosity of 9,000 to 20,000 cps; 50 to 200 parts by weight of a filler containing 60 to 80% by weight of silica sand or recycled fine aggregate with an average particle size of 1.5 to 2.4 mm and 5 to 20% by weight of calcium carbonate; 5 to 20 parts by weight of the anti-icing composition; An anti-icing pavement material that exhibits anti-slip performance can be manufactured by including 0.5 to 5 parts by weight of a hardener.

Here, the methyl methacrylate (MMA) resin has excellent adhesion to the road surface, elongation, and constructability, and is used for floor paving or as a flooring material to prevent slipping.

However, when the methyl methacrylate (MMA) resin is used only with a certain viscosity, there is a problem of reduced adhesion and durability, so in the present invention, a mixture of low-viscosity MMA resin, medium-viscosity MMA resin, and high-viscosity MMA resin is used. do.

Specifically, in the present invention, 5 to 30 wt% of low viscosity methyl methacrylate resin (MMA) with a viscosity of 5 to 1,000 cps, and 20 to 50 wt% of medium viscosity methyl methacrylate resin (MMA) with a viscosity of 3,000 to 8,000 cps. , 20 to 75% by weight of high viscosity methyl methacrylate resin with a viscosity of 9,000 to 20,000 cps is used.

At this time, if the content of the low-viscosity MMA resin is less than 5% by weight, the adhesion to the road surface is low and problems of easy separation may occur. If it exceeds 30% by weight, the problem of delayed curing may occur, and the medium-viscosity MMA resin may If less than 20% by weight is mixed, miscibility with the high-viscosity MMA resin and low-viscosity MMA resin decreases, resulting in lowered dispersibility, and if it exceeds 50% by weight, there is a risk that the overall physical properties may decrease, and the content of the high-viscosity MMA resin is 20%. If it is less than 75% by weight, the strength and durability are reduced, and if it is more than 75% by weight, the toughness is weak and may easily separate from the road surface.

Therefore, anti-slip packaging compositions incorporating MMA resins with different viscosities as described above have excellent bonding power with the road surface and provide strong bonding strength to the anti-slip filler and anti-icing material composition, resulting in anti-slip performance with excellent durability and mechanical strength. It is possible to construct a pavement layer to prevent freezing of the road surface.

In addition, as another aspect, the anti-icing pavement material can be applied to an elastic pavement surface formed on floors including indoor and outdoor floors, sports facility floors, and playground floors to exhibit anti-slip performance and road surface ice prevention performance.

In addition, as another aspect, the road surface anti-icing pavement material of the present invention includes 100 parts by weight of an asphalt concrete pavement composition or a cement concrete pavement composition; It may be comprised of 10 to 30 parts by weight of the anti-icing material composition.
