1 is a process chart showing a construction method of an eco-friendly elastic packaging material according to the present invention, Figure 2 is a cross-sectional view showing an example of the elastic packaging material 10 constructed by the construction method of the eco-friendly elastic packaging material according to the present invention.

As shown in Figure 1, the construction method of the environment-friendly elastic packaging material according to the invention, (a) applying a primer mixture on the road surface to form a primer layer (100) (S100); (B) forming an elastic layer (200) by applying a rubber chip mixture comprising a rubber chip and a binder having an average particle size of 0.5 to 2.0 mm on the upper surface of the primer layer (100) (S200); (C) forming a sealing layer (300) by applying a sealing material mixture including a rubber powder having an average particle size of 0.05 to 0.5 mm on the upper surface of the elastic layer (200); (d) applying a urethane mixture to the upper surface of the sealing layer 300 to form a urethane layer 400 (S400); And (e) applying a top coating material mixture to the upper surface of the urethane layer 400 to form a top coating layer 500 (S500).

As shown in Figure 2, the elastic packaging material 10 constructed in the same manner as the primer layer 100, elastic layer 200, sealing layer 300, urethane layer 400 and top coating layer 500 It has a structure that includes, and the durability is improved, it can be applied to walkways, bicycle paths, such as walkways, rivers and parks, as well as outdoor and indoor stadiums of schools or public sports facilities.

The step (a) is a step of forming a primer layer 100 by applying a primer mixture on the road surface, the primer layer 100 serves to bond the road surface and the elastic layer 200 to be described later, on the road surface It serves to fill the existing micro cracks or surface defects (S100).

In the construction method of the elastic packaging material according to the present invention, the primer mixture is applied to the surface of the pavement surface formed of concrete, asphalt concrete, color cone, permeable cone, and the like on the bumpy road surface to form the primer layer 100 on the road surface. In particular, it can be applied for the formation of a field-based elastic packaging material, such as a tennis court, basketball court, volleyball court, badminton court, squash court and the like.

In this step, any conventional method of applying a solution may be used without limitation, and the primer layer 100 may be formed by applying and curing the primer mixture on the road surface. Preferably, the primer layer 100 may be formed by effectively infiltrating the primer mixture into cracks or voids formed on the road surface by spraying the primer mixture on a road surface with equipment such as an airless or air gun.

In addition, the primer mixture may use a primer of a variety of conventional materials used in the art to provide a sufficient bonding strength to the road surface and the elastic layer 200 during construction on the road surface. For example, when the road surface layer is made of concrete, a concrete construction primer such as a urethane coat containing an elastic urethane resin may be used, and when the road layer is made of ascone, an asphalt concrete mixed with a volatile solvent may be used. have.

In particular, the primer mixture may be a primer having excellent adhesion to the rubber layer to be described later, preferably, the primer mixture is a melt and a polyol mixed with a urethane rubber or chloroprene rubber and a solvent in a weight ratio of 1: 1, respectively. Mixtures may be used, and such primer mixtures may include the polyol and lysate in a weight ratio of 1: 1 to 5: 1, respectively. Alternatively, the primer mixture may be a mixture containing an acrylic copolymer resin, oleic acid and water, and mixed with water in a mixture of the acrylic copolymer resin and oleic acid in a weight ratio of 1: 1 to 5: 1. Such a primer mixture may include the mixture and water in a weight ratio of 1: 1 to 1: 4, respectively, to provide excellent adhesion to the rubber layer.

In addition, when using a mixture of a urethane rubber, a solvent and a polyol as the primer, it is preferable to apply such a mixture to the road surface with a coating amount of 0.3 to 1.0 kg / m ^2, the application amount when the coating amount is less than 0.3 kg / m ² Less, there is a possibility that the road surface penetration of the primer on the road surface is lowered, and when the coating amount exceeds 1.0 kg / m ² , the road surface penetration of the primer can be improved, but it is difficult to expect the effect of further bonding strength.

The primer layer 100 may be formed in various thicknesses to suit the road surface characteristics of the construction area, such as sidewalks, walkways, stadiums, etc., preferably, may be formed in a thickness of 0.1 to 0.5 mm, more preferably To form a thickness of 0.2 to 0.3 mm can be configured to provide a uniform bonding force of the road surface and the elastic layer 200 to be described later.

The step (b) is to form an elastic layer 200 by applying a rubber chip mixture including a rubber chip and a binder having an average particle size of 0.5 to 2.0 mm on the upper surface of the primer layer 100 The elastic layer 200 has a structure in which rubber chips are bonded to each other by a binder to form voids therein. The elastic layer 200 can be installed on bumpy surfaces, roads, rivers, and parks. When walking or exercising on a promenade, a bicycle road, various stadiums, or the like, an elastic packaging material 10 may be formed to provide excellent elasticity and a pleasant and light walking feeling (S200).

The rubber chip may be made of a material consisting of ethylene propylene diamine monomer (EPDM), urethane rubber (UR), chloroprene rubber (CR), styrene butadiene rubber (SBR), waste tire, waste polyurethane, or a mixture thereof. Preferably, a rubber chip made of EPDM or UR may be used. In particular, the rubber chip may be used having an average particle size of 0.5 to 2.0 mm, when the average particle size of the rubber chip is less than 0.5 mm there is a problem that it is difficult to supply sufficient elasticity due to the narrow pores of the rubber chip, When the average particle size of the rubber chip exceeds 2.0 mm, the particle size of the rubber chip is large, there is a problem that the bonding force of the binder and the rubber chip is lowered and the breakage caused by external impact easily occurs.

The binder may be a binder including a urethane-based, epoxy-based or acrylic-based resin to wrap the rubber chip, and provides a bonding force between the rubber chips to provide a bonding force that does not occur peeling of the rubber chip in the elastic packaging material (10). Preferably, a binder including a polyurethane-based resin may be used to increase the bonding force between the rubber chips to provide wear resistance, flexibility, heat resistance, and chemical resistance of the elastic layer 200.

The rubber chip mixture may include 70 to 90% by weight of the rubber chip, 10 to 30% by weight of the binder, and when the content of the binder is less than 10% by weight, it is difficult to induce sufficient bonding force between the rubber chips. If the content exceeds 30% by weight, there is a problem that the elasticity is lowered. More preferably, the rubber chip mixture may impart excellent elasticity, including 20 to 30% by weight of charcoal powder and antibacterial material, 15 to 20% by weight of the binder and the remaining rubber chips, and a rubber chip mixture having such a composition Silver specific gravity has 0.6 to 0.8.

In this step, if the application method of the conventional solution is not limited, the rubber chip mixture may be applied to the road surface and then cured to form the elastic layer 200, and the elastic layer 200 may be applied to the construction of the elastic packaging material 10. It can be formed in various thicknesses as needed due to the road surface or consumer demand.

Preferably, the elastic layer 200 may be formed to a thickness of 1.0 to 100.0 mm on the upper surface of the primer layer 100 formed on the road surface, if the thickness of the elastic layer 200 is less than 1.0 mm impart sufficient elasticity Has a hard problem. More preferably, the elastic layer may be formed of an irregular packaging having a height of 10 mm to 30 mm to form a thickness of 15 to 50 mm on the road surface having a macro surface roughness to construct an elastic packaging material having a constant elasticity. .

In addition, the elastic layer 200 may use rubber chips having different average particle sizes, and may adjust a bonding area between rubber chips by adjusting a mixing ratio, thereby improving tensile strength.

For example, the elastic layer 200 is a rubber chip by mixing a rubber chip having an average particle size of 0.5 to 0.8 mm and a rubber chip having an average particle size of 1.0 to 2.0 mm in a weight ratio of 2: 8 to 3: 7, respectively. By increasing the bonding area between the elastic layer 200 can be formed significantly improved tensile strength.

In addition, the rubber chip mixture may further include activated carbon powder or charcoal powder and an antimicrobial material to reduce the divergence of the unique rubber aroma of the rubber chip, and may provide antimicrobial properties to form an eco-friendly elastic packaging material 10.

The activated carbon powder or charcoal powder may have a porous particle structure to effectively collect odors unique to rubber chips, and the antimicrobial material remains in the elastic layer 200 for a long time to prevent the growth of microorganisms continuously. Do it.

The antimicrobial material may be used a variety of conventional materials, and natural antibacterial agents such as metal particles such as silver, copper, zinc, mustard, cypress, isopropylmethylphenol, silicon alkoxide, methyldibromo glutaronitrile, thiobenda Organic materials such as sol (TBZ), bisphenol, quaternary ammonium salt, TiO ₂ , ZnO ₂ , ZnO, SrTiO ₃ , CdS, GaP, InP, GaAs, ZrPO ₄ , BaTiO ₃ , KNbO ₃ , Fe ₂ O ₃ , Metal oxides such as Ta ₂ O ₅ , WO ₃ , SnO ₂ , Bi ₂ O ₃ , NiO, Cu ₂ O, SiO, SiO ₂ , MoS ₂ , InPb, RuO ₂ or CeO ₂ and the like can be used. Preferably, a nanoparticle sized composite antimicrobial material prepared by coupling a mixture containing isopropylmethylphenol, silicon alkoxide and TiO ₂ may be used to impart excellent antimicrobial effect. In particular, when using a nanoparticle-size composite antimicrobial material containing isopropylmethylphenol, silicon alkoxide and TiO ₂ as the antimicrobial material, the charcoal powder and the antimicrobial material is in the ratio of 1 to 5% by weight of the rubber chip By mixing the mixture to form an elastic layer 200 to form an elastic layer 200 having excellent antimicrobial properties, more preferably, the charcoal powder and the antimicrobial material to be added in a ratio of 2 to 4% by weight Can be.

In addition, as shown in FIG. 3, in the present step, after the elastic layer 200 is formed, the elastic layer 200 is horizontally or vertically spaced at a predetermined interval on the upper surface of the elastic layer 200 before curing. The method may further include forming an uneven portion 210 in a direction, whereby the elastic layer 200 having the uneven portion 210 as illustrated in FIG. 3 may be formed.

Specifically, by configuring the sealing material and urethane to be described later sequentially through the uneven portion 210 formed in the elastic layer 200 as described above, the sealing layer 300 and the urethane layer 400 formed in the steps to be described later Since the urethane liquid is injected into the concave-convex portion 210 which is sequentially stacked, the bonding force between the elastic layer 200, the sealing layer 300, and the urethane layer 400 is increased, and thus the urethane layer ( It is possible to prevent the 400 is separated to improve the long-term durability of the elastic packaging material (10).

The concave-convex portion 210 may be formed by applying a rubber chip mixture to the upper surface of the primer layer 100, and then fixing the mold to the upper surface before the mixture is cured to form the elastic layer 200. In addition, the irregularities 210 may be formed to have a width of 10 to 15 cm, and the irregularities 210 having various grid patterns having a predetermined pattern may be formed.

The step (c) is a step of forming a sealing layer 300 by applying a sealing material mixture containing a rubber powder having an average particle size of 0.05 to 0.5 mm on the upper surface of the elastic layer 200, the sealing The layer 300 fills up a large number of voids formed on the surface of the elastic layer 200 to planarize the top surface of the elastic layer 200, and to generate pores between the urethane layer 400 and the rubber layer, which will be described later. By preventing it serves to form an elastic packaging material 10 having a uniform strength (S300).

Specifically, the void formed on the surface of the elastic layer 200 prevents the uniform application of the liquid urethane at the time of forming the urethane layer 400 to be described later, between the elastic layer 200 and the urethane layer 400 The formed pores serve to hinder the formation of uniform strength, and in this step, in order to prevent such a reverse function, by applying a sealing material on the surface of the elastic layer 200 to achieve pore removal and planarization on the surface, the elastic layer The bonding force of the 200 and the urethane layer 400 may be improved.

To this end, the sealing layer 300 may be formed by applying a mixture containing a sealing material and rubber powder made of a material such as polyurethane resin, acrylic resin or polyester resin on the upper surface of the elastic layer 200. In particular, in this step, since the mixture including the rubber powder and the sealing material having a fine average particle size compared to the rubber chip is applied to the upper surface of the elastic layer 200, the pore size is very good and the surface of the elastic layer 200 is very good. Can be flattened.

To this end, the sealing material mixture may comprise a rubber powder having a particle size of 0.05 to 0.5 mm, preferably, the sealing material mixture may comprise a rubber powder in a proportion of 3 to 10% by weight. When the rubber powder included in the sealing material mixture is included in an amount of less than 3% by weight, there may be a problem that it is difficult to densely fill voids formed in the elastic layer 200, and when included in a range exceeding 10% by weight of the sealing layer ( 300) there is a problem that is difficult to planarize the surface. More preferably, the sealing material mixture may comprise a rubber powder in a ratio of 5 to 7% by weight.

The step (d) is a step of forming a urethane layer 400 by applying a urethane mixture on the upper surface of the sealing layer 300, the urethane layer 400 provides excellent elasticity and comfortable and light walking feeling, It plays a role of imparting characteristics such as repulsive force, grip force, slip resistance, and shock absorbing force (S400).

In this step, if the application method of the conventional solution is not limited, the urethane mixture may be applied to the upper surface of the sealing layer 300 and then cured to form the urethane layer 400. The urethane mixture may include a main material, a curing agent, and a solvent. It can be prepared by mixing. The urethane mixture may be prepared using urethane as the subject, isocyanate as the curing agent, and petroleum solvent as the solvent. In addition, the urethane mixture may further include calcium carbonate, the calcium carbonate as such serves to improve the mechanical properties of the urethane layer 400, 10 to 30 weight based on the total weight of the urethane mixture The urethane layer 400 may be formed by applying a mixture of urethane mixed at a ratio of%.

In addition, the urethane layer 400 suitable for road surface characteristics and purposes is formed by separately forming a hard urethane layer, a soft urethane layer, and a semi-hard urethane layer by using a hard urethane, a soft urethane, and a curable agent to form a rigid urethane and a semi-hard urethane. The elastic packaging material 10 may be constructed, and the urethane mixture as described above may be prepared by mixing the main material and the curing agent in a weight ratio of 1: 1 to 1: 3, respectively, depending on the climatic conditions of the solvent. The urethane layer 400 may be formed by using a mixture of urethanes in which the amount of the mixture is adjusted.

Specifically, the road surface on which stable packaging material is formed on the ground such as concrete, ascon, color cone, and pitching cone may be coated with a semi-cured urethane or a soft urethane mixture to form a semi-rigid or soft urethane layer. In the lowermost surface, after forming the soft urethane, the hard urethane may be applied to the upper surface of the soft urethane, and the soft or semi-hard urethane may be applied to the upper surface of the hard urethane to form the urethane layer 400, thereby forming The elastic control of the elastic packaging material 10 can be adjusted, and in this way it is possible to form the urethane layer 400 in various combinations.

In addition, in this step, the urethane layer 400 may be formed to a thickness of 1 to 10 mm to form an elastic packaging material 10 having excellent airtightness and elasticity.

Preferably, the urethane mixture may be prepared by mixing with 9 parts by weight of the subject matter forming the semi-hard urethane and 22.5 parts by weight of the curing agent and the petroleum-based solvent to be uniformly mixed, 0.3 to 1.0 kg / m ² The urethane layer 400 may be formed by applying the coating amount, and when the urethane mixture is applied, the urethane layer 400 formed in one coating is formed to a thickness of 0.7 to 1.5 mm. Therefore, in this step, the thickness of the urethane layer 400 can be adjusted by repeatedly applying the urethane mixture one or more times to repeatedly laminate the urethane, and the road surface or the consumer's request for the construction of the elastic packaging material 10. Therefore, it can be formed in various thicknesses as needed.

More preferably, when the urethane layer 400 is formed by constructing the elastic packaging material 10 on a road surface having a constant surface roughness, the liquid phase including semi-rigid urethane is repeated twice on the upper surface of the sealing layer 300. The urethane layer 400 is formed to apply uniformly to the basketball ball having a thickness of 3 mm to be uniformly formed to form an elastic packaging material 10 for a basketball court having uniform ball-bound properties.

In addition, in this step, an uneven road surface, in particular, an uneven surface having a height of 10 mm to 100 mm is formed, thereby constructing the elastic packaging material 10 without performing a separate compaction or road leveling work on a road surface having a macro surface roughness. can do. However, when the elastic packaging material 10 is applied to a road surface having a high surface roughness, since the thickness of the elastic layer 200 formed on the uneven portion becomes thick, it is difficult to form the elastic packaging material 10 having regular elasticity. have.

In order to solve the above problems, in this step, by applying a liquid mixture containing a flexible urethane on the upper surface of the sealing layer 300 to form a flexible urethane layer with a thickness of 0.5 to 3 mm, the hard surface of the flexible urethane layer Urethane is applied to form a rigid urethane layer with a thickness of 0.5 to 3 mm, and then a semi-hard urethane is applied to the upper surface of the rigid urethane layer to form a semi-hard urethane layer with a thickness of 0.5 to 4 mm to form a composite urethane layer (400). In order to prevent the elastic irregularity due to the increase in the thickness of the elastic layer 200 to form an elastic packaging material 10 having a uniform elasticity can be formed.

In particular, when the elastic packaging material is formed by forming an elastic layer 200 with a thickness of 15 to 50 mm on the road surface having a rough surface roughness of 10 mm to 30 mm height is formed, the thickness of 1 to 2 mm It is preferable to form a composite urethane layer 400 formed with a flexible urethane layer, a rigid urethane layer of 1 to 2 mm thick, a semi-hard urethane layer of 1 to 2 mm thick, thereby increasing the thickness of the elastic layer The elastic irregularity can be prevented to form an elastic packaging material having uniform elasticity, and can be utilized for construction in stadiums such as basketball courts, tennis courts, and soccer fields.

Furthermore, in the present invention, in order to control the elasticity of the elastic packaging material to be applied, the thickness of the soft, hard and semi-hard urethane layer formed on the composite urethane layer 400 may be adjusted.

The step (e) is a step of forming a top coating layer 500 by applying a mixture including a top coating material on the top surface of the urethane layer 400, the top coating layer 500 is the top surface of the urethane layer 400 It protects and minimizes the degeneration, wear and discoloration due to deterioration of the urethane layer 400 due to long-term use, and serves to give color to the elastic packaging material 10, giving antimicrobial properties to the upper surface of the elastic packaging material (10) It serves to protect the user from microorganisms (S500).

The top coating layer 500 is preferably used by selecting a top coating material made of a material resistant to abrasion, it can be formed using a variety of top coating materials such as acrylic copolymer emulsion commonly used. In particular, the top coating material is excellent modification and wear protection functionality by the acrylic copolymer emulsion using a top coating material containing an acrylic copolymer and a fluorine-modified polyurethane containing fluorine in a ratio of 1: 1 to 9: 1, respectively. It is possible to impart excellent ultraviolet resistance and weather resistance by the fluorine-modified polyurethane, and more preferably, the top coating material may be one containing an acrylic copolymer and a fluorine-modified polyurethane in a ratio of 5: 1, respectively. have.

In addition, the top coating material mixture may include ceramic particles, such as silica and zeolite, to exhibit a slip preventing function, and may include various colors to the elastic packaging material 10 including pigments.

The pigment may be used without limitation inorganic pigments or organic pigments that are commonly used, preferably, it may be used a material that does not contain chromium, lead, etc., harmless to the human body. As the pigment, red or yellow color may be imparted to the inorganic particles such as barium sulfate, talc, kaolin or calcium carbonate using an eco-friendly pigment in which yellow iron oxide or red iron oxide is introduced, and copper phthalocyanine green is introduced into the inorganic particles. Can be used for imparting blue color.

In addition, the pigment in the above may be used by mixing in a ratio of 1 to 5 parts by weight relative to the top coating material mixture, there is a fear that the color is not clearly expressed on the elastic packaging material 10 when the mixing amount of the pigment is less than 1 part by weight. When the mixing amount of the pigment is more than 5 parts by weight, the color is excessively imparted due to the excessive mixing amount of the pigment, which may change the color when used for a long time.

In addition, in this step, after forming the top coating layer 500 as described above to construct the elastic packaging material 10, a line marking for applying a paint, pigment, etc. on the top coating layer 500 of the elastic packaging material 10 Can be used to create a line conforming to stadium rules, or to form a line that can indicate that it is a walkway or aisle, or use conventional materials such as acrylic paint for line marking, masking tape for accurate line formation. (Masking Tape) can be used for line marking.

In addition, according to the construction method of the elastic packaging material according to the present invention, performing the step of forming the primer layer 100, the elastic layer 200, the sealing layer 300, the urethane layer 400 in each step as described above After laminating each layer in the process, it may be configured to further include a step of uniformly flattening using a roller or the like to construct an elastic packaging material 10 having a low surface roughness and a uniform thickness and surface.

In addition, the present step is configured to further include the step of applying a natural antibacterial mixture containing cypress stock solution or nano-antibacterial material on the upper surface of the elastic packaging material 10 formed on the road surface in the same manner as the elastic packaging material 10 To give antibacterial to and sterilize various microorganisms and pollutants can form an environmentally friendly elastic packaging material (10).

Specifically, the cypress stock solution is stable to the human body as a natural product, gives a natural deodorizing effect of removing the characteristic rubber odor remaining in the elastic packaging material 10, and has an effect of neutralizing by combining with harmful organic compounds, Contains a large amount of phytoncide, which has an antibacterial effect. Preferably, the cypress stock solution may be a mixture containing a cypress extract and cypress oil, and the nano-antibacterial material may use the above-described antimicrobial material, a detailed description thereof will be omitted.

According to the construction method of the eco-friendly elastic packaging material according to the present invention as described above, it is possible to construct an elastic packaging material excellent in elasticity and durability by using an environmentally friendly material with less human stimulation and antibacterial activity.

Particularly, in the construction method, an elastic layer including a rubber chip may be formed to directly form an elastic packaging material in a bumpy base layer.
