Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in each drawing refer to the same components.

1 is a conceptual diagram showing a schematic configuration of the artificial turf of the present invention.

The artificial turf having an antistatic function of the present invention comprises a base material of any one of polyurethane, polyvinylidene chloride, polyethylene, polypropylene, nylon, or a mixture thereof, an alkylpyridinium salt, or an alkylimidazolinium salt. Alternatively, an antistatic agent including a mixture thereof may be included.

The base material is the main material of artificial turf, and may be radiated in the shape of artificial turf through a separate radiator or the like to become artificial turf. At this time, polyvinylidene chloride, polyethylene, polypropylene, and nylon, which can be used as base materials, are synthetic fiber materials, and if artificial turf is manufactured using these materials, it can be used year-round regardless of weather conditions, and always maintains the shape of the turf. Therefore, it has the advantage of being relatively easy to manage after installation.

At this time, when various activities such as walking or exercising on the installed artificial turf are performed, friction inevitably occurs.Since the artificial turf uses the aforementioned synthetic fiber base material as the main material, electrification occurs well. It is done. Specifically, the charging phenomenon refers to a phenomenon in which a large number of charges are exposed when the balance between positive and negative charges is broken due to the movement of electrons due to an impact or friction, and the magnitude of the electric force received from the atom by the electrons constituting the atom depends on the object. When different types of objects are attached and removed, electrons are charged from an object with a weak electric force to an object with a strong electric force.

For example, the charging phenomenon will be described as an example, when the hair is combed, electrons in the hair move to the comb, and the hair that has lost electrons takes on positive electricity, and the comb that acquires electrons takes on negative electricity, which may generate electrostatic force.

Due to this charging phenomenon, artificial grass sticks to the clothes and shoes of users, or charges generated by the charging shape move through the user's body, causing static electricity to occur when the user's body comes into contact with other objects or others. You can follow this.

At this time, since the artificial turf contains an antistatic agent, it is possible to effectively prevent static electricity from being charged from friction of the artificial turf. Here, since the alkylpyridinium salt and the alkylimidazolinium salt of the antistatic agent are one type of cationic surfactant, they can adsorb negative charges, thereby preventing static electricity due to the charging phenomenon. In addition, these cationic surfactants can perform a bactericide, thereby preventing the infestation of bacteria and bacteria that may occur in artificial turf.

In addition, the artificial turf of the present invention is manufactured by basically including a base material and an antistatic agent, but in order to improve the function of the artificial turf, it is also possible to mix together other additives such as a high water-containing resin and a dye.

At this time, the artificial turf may be prepared including 0.01 to 5% by weight of the antistatic agent based on the total weight of the artificial turf, and the antistatic agent is specifically based on the total weight of the antistatic agent, 20 to 35% by weight of alkylpyridinium salt, and alkyl It may be a mixture of 20 to 35% by weight of imidazolinium salt, 10 to 25% by weight of polyaniline, and 10 to 25% by weight of polypyrrole.

Here, the alkylpyridinium salt and the alkylimidazolinium salt are a kind of cationic surfactant, as described above, and are substances capable of adsorbing negative charges and thus preventing charging. In addition, polyaniline and polypyrrole are one type of conductive polymer, and when anions are generated through charging, they move into the conductive polymer to absorb them, thereby preventing the charging phenomenon. Therefore, the antistatic agent including the above-described materials can effectively prevent the generation of electrostatic force due to the charging phenomenon by preventing the separation of positive and negative ions.

Figure 2 is a flow chart showing a method of manufacturing the core material of the antistatic agent of the present invention.

In addition, the antistatic agent can effectively reduce static electricity generated due to the charging phenomenon by additionally including an antistatic agent including poly(carbonate diol).

Specifically, based on the total weight of the antistatic agent, 20 to 30% by weight of an alkylpyridinium salt, 20 to 30% by weight of an alkylimidazolinium salt, 10 to 20% by weight of polyaniline, 10 to 20% by weight of polypyrrole, The antistatic agent may be added in an amount of 5 to 15% by weight.

These antistatic agents are in the form of capsules in which a core material containing poly(carbonate diol) is encapsulated by being encapsulated by a coating film, whereby the effect of preventing static electricity can be stably lasted for a long time. .

At this time, the core material of the antistatic agent is the first solution manufacturing step (S110), the second solution manufacturing step (S111), the third solution manufacturing step (S112), the fourth solution manufacturing step (S113), and the core material completion step (S114). ) Can be manufactured.

First, the first solution preparation step (S110) is performed by mixing 50 to 80% by weight of IPDI (isophrone diisocyanate) and 20 to 50% by weight of poly(carbonate diol) based on the total weight of the first solution. It is the process of preparing a solution.

Here, IPDI is a kind of aliphatic diisocyanate, and can form a polyurethane prepolymer by reacting with polycarbonate diol and DMPA, which will be described later. In addition, the polycarbonate diol plays a role as a polyol that contributes to the formation of a polyurethane prepolymer.

Next, the second solution preparation step (S111) is a secondary solution by mixing 70 to 95% by weight of 1-methyl-2-pyrolidinone (NMP) and 5 to 30% by weight of dimethylol propionic acid (DMPA) based on the total weight of the second solution. It is a process of preparing a solution, and the third solution preparation step (S112) includes 50 to 70% by weight of the first solution, 20 to 40% by weight of the second solution, and 0.1 to 10% by weight of dibutyltin dilaurate (DBTL) based on the total weight of the third solution. % Is mixed and heated at 70 to 80° C. for 2 to 5 hours to prepare a tertiary solution, and it is preferable to proceed with stirring at a speed of 400 to 600 rpm.

Here, NMP serves as a solvent for dissolving DMPA, and DMPA may react with the aforementioned IPDI and polycarbonate diol to form a polyurethane prepolymer. At this time, DBTL plays a role as a catalyst for the polyurethane prepolymer formation reaction.

Next, the fourth solution preparation step (S113) is a mixture of 70 to 90% by weight of the third solution, 5 to 20% by weight of aniline, and 1 to 10% by weight of triethylamine (TEA) based on the total weight of the fourth solution. Then, it is a process of preparing a quaternary solution by heating at 40 to 60° C. for 30 to 100 minutes. Here, the aniline may be modified into a polyurethane prepolymer having an aniline end group by capping an NCO group, which is an end group of the formed polyurethane prepolymer. In addition, triethylamine serves as a neutralizing agent. At this time, the polyurethane prepolymer produced by the reaction has adhesion properties, so that it can be better mixed with other components of the artificial turf including the base material, and the durability of the artificial turf can be improved.

Finally, the core material completion step (S114) is a mixture of 65 to 85% by weight of the fourth solution, 5 to 30% by weight of carbon nanotubes (CNT), and 1 to 10% by weight of ethylenediamine (EDA) based on the total weight of the core material. It is a process of completing the core material by stirring for 10 to 40 minutes at a speed of 800 to 1200 rpm. Here, ethylenediamine plays a role as a chain extender, and CNT improves the mechanical strength of the core material and imparts conductivity to effectively prevent static electricity.

At this time, the above-described core material completion step (S114) may further effectively reduce static electricity generated due to the charging phenomenon by additionally including dimethyl sulfate and DMAEMA (dimethyl aminoethyl methacrylate).

Specifically, in the core material completion step (S114), based on the total weight of the core material, the fourth solution 65 to 75% by weight, carbon nanotubes (CNT) 5 to 20% by weight, ethylenediamine (EDA) 1 to 5% by weight, the After mixing 10 to 25% by weight of dimethyl sulfate and 1 to 10% by weight of DMAEMA (Dimethyl Aminoethyl Methacrylate), the core material may be completed by stirring for 10 to 40 minutes at a speed of 800 to 1200 rpm.

Here, DMAEMA is a substance having a ?N functional group, and can ammonium dimethyl sulfuric acid by reacting with dimethyl sulfuric acid. This ammonium dimethyl sulfuric acid can effectively prevent the charging phenomenon that may occur in artificial turf.

Figure 3 is a flow chart showing a method of manufacturing a coating film of the antistatic agent of the present invention.

In addition, the coating film of the antistatic agent may be manufactured through a first mixed solution manufacturing step (S120), a second mixed solution manufacturing step (S121), a coating agent manufacturing step (S122), and a coating film completion step (S123).

First, the first mixed solution preparation step (S120) is based on the total weight of the first mixed solution, 55 to 70% by weight of water, 25 to 35% by weight of PVA (Poly (vinyl alcohol)), PEG (Poly(ethylene glycol)) 5 After mixing to 15% by weight and heating at 80 to 95 °C, the first mixed solution is in the process. Here, PVA has excellent mechanical properties and can be solidified later to form a gel-like film. In addition, PEG is an additive for inducing hydrogen bonding between molecules of the PVA chain or intramolecularly.

Next, in the second mixed solution preparation step (S121), 30 to 80% by weight of dichloromethane and 20 to 70% by weight of PLGA (poly(lactic-co-glycolic acid)) are mixed, based on the total weight of the second mixed solution. As a process for preparing the second mixed solution, it is preferable to prepare by stirring for 5 to 10 minutes at a speed of 15,000 to 25,000 rpm.

Here, dichloromethane serves as a solvent capable of dissolving PLGA, and PLGA is simply hydrolyzed and solidified as a biotype polymer capable of gradually releasing the core material inside the coating film, thereby forming a membrane.

Thereafter, the coating agent manufacturing step (S122) is a process of preparing a coating agent by mixing 50 to 70% by weight of the first mixed solution and 30 to 50% by weight of the second mixed solution, based on the total weight of the coating agent, and completing the coating film (S123 ) Is a process of cooling the coating agent to complete the coating film.

The coating agent completed through this process can be solidified to form a coating film having excellent physical properties, thereby stably protecting the above-described core material. As a result, it is possible to stably sustain the antistatic effect of the core material for a long time.

In another embodiment, the artificial turf can not only enhance the mechanical properties of the artificial turf, but also reduce static electricity due to the charging phenomenon by additionally including carbon powder containing 1 to 5% by weight of carbon black based on the total artificial turf weight. have.

Figure 4 is a flow chart showing a method of manufacturing the carbon powder of the present invention.

These carbon powders include a first mixture production step (S210), a second mixture production step (S211), a first washing step (S212), a third mixture production step (S213), a fourth mixture production step (S214), and the second It may be manufactured through the washing step (S215).

First, in the first mixture preparation step (S210), 0.1 to 10% by weight of carbon black and 90 to 99.9% by weight of methylene chloride are mixed with respect to the total weight of the first mixture, followed by ultrasonic treatment for 5 to 30 minutes to prepare a first mixture. It is a process.

At this time, carbon black refers to soot composed only of carbon, and is a main material of carbon powder, and methylene chloride serves as a dispersion medium for carbon black, and ultrasonic treatment is performed so that the carbon black is well dispersed in methylene chloride.

Next, the second mixture preparation step (S211) is based on the total weight of the second mixture, the first mixture 65 to 85% by weight, TPABr (Tetrapropylammonium bromide) 0.1 to 10% by weight, acetic acid 1 to 20% by weight, potassium permanganate 5 It is a process of preparing a second mixture by mixing to 25% by weight and 1 to 20% by weight of water.

At this time, TPABr serves as a phase transition catalyst of the first mixture, acetic acid is to provide an acet group to the carbon black of the first mixture, and potassium permanganate serves as an oxidizing agent.

Thereafter, the first washing step (S212) is to wash the second mixture 1 to 5 times with methanol, and sufficiently wash the second mixture with methanol so that TPABr, acetic acid, and potassium permanganate remaining in the second mixture are removed (preferably 3 to 5 times) It is possible to obtain a carbon black whose surface has been modified with an acet group.

Next, the third mixture preparation step (S213) is performed by mixing 1 to 10% by weight of the washed second mixture and 90 to 99% by weight of toluene based on the total weight of the third mixture, followed by ultrasonic treatment for 1 to 20 minutes. 3 This is a process of preparing a mixture, in which a second mixture is dispersed in toluene, a solvent, by ultrasonic treatment, thereby preparing additional surface modification of carbon black.

Thereafter, the fourth mixture preparation step (S214) is performed by mixing 80 to 95% by weight of the third mixture, 1 to 10% by weight of catalyst, and 0.1 to 10% by weight of hydroquinone relative to the total weight of the fourth mixture and raising the temperature to 100°C. Then, the mixture is stirred for 3 to 8 hours to prepare a fourth mixture.

In this case, the catalyst may be 3-Mercaptopropyl trimethoxysilane (MPTMS), and the catalyst allows the surface modification reaction of the third mixture to be rapidly performed. In addition, hydroquinone serves to stabilize the third mixture and prevent oxidation. The surface of the fourth mixture thus prepared has a hydroxyl group by the toluene.

Finally, the second washing step (S215) is to wash the fourth mixture 1 to 5 times with methanol, and finally by removing the toluene, catalyst, and hydroquinone remaining in the fourth mixture through the washing process. This is the process of completing the surface-modified carbon powder.

As the surface of the carbon powder prepared in this way is modified with an acet group and a hydroxyl group, the water dispersibility is increased, so that the blendability with other components of the artificial turf may be excellent. In addition, when the carbon powder is included, the durability and elasticity of the artificial turf may be increased, and thus damage and shape deformation caused by frequent use of the artificial turf may be reduced.

In addition, by additionally steam-treating the carbon powder prepared through the above-described process, the durability and mechanical properties of the carbon powder can be further strengthened to provide a more stable artificial turf. It may include a step, a calcining step, a second material manufacturing step, a third material manufacturing step, a fourth material manufacturing step, a supporting step, and a washing step.

First, the first material preparation step is 3 to after mixing 30 to 70% by weight of _{nickel hydroxide (Ni(OH) 2} ) and 30 to 70% by weight of magnesium hydroxide (Mg(OH) _{2) based on the total weight of the first material.} This is a process of manufacturing a first material by ball-milling at 1000 to 2000 rpm for 6 hours.

At this time, nickel hydroxide and magnesium hydroxide serve to promote the growth of carbon powder, and nickel hydroxide and magnesium hydroxide are mixed and pulverized through a ball milling method. Here, ball milling uses an alumina ball having a diameter of 4 to 6 mm, and in order to reduce mixing of impurities due to abrasion of the alumina ball during ball milling, nickel hydroxide and magnesium hydroxide are added to a container made of agate material to be mixed and pulverized. It is desirable to prepare 1 material.

Next, the calcination step is a process of calcining the first material at 400 to 700°C for 2 to 6 hours under an atmospheric airflow, and the first material in the form of a mixed powder is calcined at a temperature condition of 400 to 700°C. It can increase the surface area of the material. Through this, the function of the first material that promotes the growth of the carbon powder may be further improved.

At this time, if the first material is calcined to less than 400°C, the surface area of the first material may not be sufficiently increased. If it exceeds 700°C, the first material may be carbonized, so that the function of the first material cannot be performed.

Thereafter, in the second material manufacturing step, 80 to 95% by weight of carbon powder and 5 to 20% by weight of the first material are mixed and then heated at a rate of 5°C/min to be 500 to 650°C, based on the total weight of the second material. Next, hydrogen gas and nitrogen gas are injected at 50 to 200 mL/min to prepare a second material.

This is a step of preparing a second material by mixing carbon powder, which is a material to be grown, and a first material that promotes the growth of the carbon powder, and then injecting hydrogen and nitrogen (ie, steam treatment).

At this time, the carbon powder is heat-treated by raising the temperature of the mixture of the carbon powder and the first material until it reaches 500 to 650°C, and the carbon powder can be grown by the first material by steam treatment by injecting hydrogen and nitrogen gas. To be there.

Next, in the third material manufacturing step, acetylene gas is injected into the second material at 1 to 50 mL/min and hydrogen gas at 50 to 200 mL/min for 30 to 60 minutes, and then maintained for 30 to 200 minutes under an argon atmosphere. It is the process of manufacturing a substance.

This is a step of manufacturing a third material by injecting acetylene gas and hydrogen gas into the second material.Since the temperature of the second material is 500 to 650°C, which is the thermal decomposition temperature of the acetylene gas, the acetylene gas is thermally decomposed by the temperature of the second material. So that more carbon can be produced. As a result, the growth of the carbon powder can be further maximized.

Further, the grown carbon powder may be completed by maintaining the second material injected with acetylene gas and hydrogen gas in an argon atmosphere.

Thereafter, in the step of preparing the fourth material, 5 to 50% by weight of the third material and 50 to 95% by weight of nitric acid are mixed and stirred, and refluxed at 50 to 80°C for 12 to 30 hours, based on the total weight of the fourth material. As a process of manufacturing, the nitric acid serves to remove nickel and magnesium remaining in the third material.

Thereafter, the supporting step is a process of supporting the fourth material in a hydrochloric acid (HCl) solution at a temperature of 100 to 150° C. for 4 to 8 hours, and the washing step is washing the fourth material supported in the hydrochloric acid solution with water 1 to 5 times. It is a process.

In this case, the process of supporting the fourth material in the hydrochloric acid solution in the supporting step is a process of purifying the fourth material from which nickel and magnesium remaining by nitric acid are removed, and the washing step is a process of washing the fourth material to remove hydrochloric acid. Step.

At this time, it is preferable that the pH of the fourth material is 7 by washing the fourth material supported in hydrochloric acid 1 to 5 times with water in the washing step.

Through such a process, the carbon powder has a large volume of itself, and mechanical properties and durability are further strengthened, thereby making it possible to manufacture a structurally stable artificial turf.
