Description
본 발명은 탄성포장재 및 이의 제조방법에 관한 것으로, 더욱 상세하게는 하이브리드 폴리우레아 바인더를 이용하여, 인장강도 및 신장율을 향상시킬 수 있는 탄성포장재 및 이의 제조방법에 관한 것이다. The present invention relates to an elastic packaging material and a manufacturing method thereof, and more specifically, to an elastic packaging material capable of improving tensile strength and elongation using a hybrid polyurea binder and a manufacturing method thereof.
일반적으로 탄성포장재는, 주행, 보행 또는 착지시 탄성변형과 함께 충격을 조절하여 발이 지면에 착지할 때 충격의 운충 특성을 구비함으로써 신체에 전달되는 부담을 경감하고 안전한 활동이 가능하도록 한다. In general, elastic packaging materials control shock along with elastic deformation during driving, walking, or landing, and have impact characteristics when the foot lands on the ground, thereby reducing the burden transmitted to the body and enabling safe activities.
주로 탄성포장재가 사용되는 스포츠 공간에 있어서는 발이 지면이 밀착 후 반작용으로 일어나는 바닥 반발력 감쇄도를 낮게 하여 주행 및 보행에 필요한 운동 특성을 좋게 하는 특징을 구비한다. 이러한 탄성포장재는 육상트랙, 농구장, 배구장, 테니스장 등의 다목적 구장과 조깅 트랙, 자전거 전용도로, 보행로, 놀이터 등의 충격 흡수용 포장재로 널리 이용되고 있으며, 사용되는 포장재의 재질에 따라 탄성 고무 포장재 및 탄성 PVC(Poly Vinnyl Chloride) 포장재 등 다양한 유형의 포장재가 사용되고 있다. 이러한 탄성포장재 및 제조공법과 관련하여 대한민국 특허공개 제2004-0072148호 등에 공개된 바 있다. In sports spaces where elastic packaging materials are mainly used, it has the feature of improving the exercise characteristics necessary for running and walking by lowering the attenuation of the floor reaction force that occurs as a reaction after the foot comes into contact with the ground. These elastic packaging materials are widely used as shock absorbing packaging materials for multi-purpose stadiums such as athletics tracks, basketball courts, volleyball courts, and tennis courts, as well as jogging tracks, bicycle paths, pedestrian paths, and playgrounds. Depending on the material of the packaging material used, they can be classified into elastic rubber packaging and Various types of packaging materials are used, such as elastic PVC (Poly Vinyl Chloride) packaging. These elastic packaging materials and manufacturing methods have been disclosed in Korean Patent Publication No. 2004-0072148, etc.
다만, 종래의 탄성포장재의 경우 폐타이어칩과 같은 폐수지칩을 사용하였다. 폐수지칩은 시간이 지남에 따라 열화되어 바닥재로서의 강도가 크게 저하되고 탈리되는 등의 문제가 발생할 뿐만 아니라, 악취, 세균증식, 오염 등의 문제가 있었다. However, in the case of conventional elastic packaging materials, waste resin chips such as waste tire chips were used. Waste resin chips not only deteriorate over time, causing problems such as greatly reduced strength as a flooring material and detachment, but also cause problems such as bad odor, bacterial growth, and contamination.

도1은 본 발명의 일 실시예에 의한 탄성포장재의 제조방법을 나타내는 순서도이다. 여기서, 탄성포장재는 보행로나 산책로, 어린이 놀이터, 물놀이 시설, 학교 운동장, 다목적 체육 시설 등에 충격흡수바닥재로 사용되는 것일 수 있다.Figure 1 is a flow chart showing a method of manufacturing an elastic packaging material according to an embodiment of the present invention. Here, the elastic packaging material may be used as a shock-absorbing flooring material for pedestrian paths, trails, children's playgrounds, water play facilities, school playgrounds, and multi-purpose sports facilities.
도1을 참조하면, 본 발명의 일 실시예에 의한 탄성포장재의 제조방법은, 하이브리드 폴리우레아 바인더 생성단계(S10), 탄성포장재 형성단계(S20) 및 코팅단계(S30)를 포함할 수 있다. Referring to Figure 1, the method of manufacturing an elastic packaging material according to an embodiment of the present invention may include a hybrid polyurea binder generating step (S10), an elastic packaging material forming step (S20), and a coating step (S30).
이하 도1을 참조하여 본 발명의 일 실시예에 의한 탄성포장재의 제조방법을 설명한다. Hereinafter, a method for manufacturing an elastic packaging material according to an embodiment of the present invention will be described with reference to Figure 1.
하이브리드 폴리우레아 바인더 생성단계(S10)에서는, 하이드록시기(hydroxyl group)를 포함하는 폴리올(polyol), 이소시아네이트기(isocyanate group)를 포함하는 이소시아네이트(isocyanate), 용제 및 아민(amine)을 혼합하여, 하이브리드 폴리우레아 바인더를 형성할 수 있다. 실시예에 따라서는, 폴리올(polyol) 60 중량%, 이소시아네이트(isocyanate) 20-30 중량%, 용제 10 중량% 및 아민(amine) 5 중량%으로 혼합할 수 있다. In the hybrid polyurea binder production step (S10), polyol containing a hydroxyl group, isocyanate containing an isocyanate group, solvent, and amine are mixed, Hybrid polyurea binders can be formed. Depending on the embodiment, 60% by weight of polyol, 20-30% by weight of isocyanate, 10% by weight of solvent, and 5% by weight of amine may be mixed.
여기서, 폴리올은 양 말단에 하이드록시기를 각각 포함하는 것일 수 있다. 예를들어, 폴리올은 폴리카보네이트 디올(Polycarbonate diol), 폴리카프로락톤 디올(Polycaprolacton diol), 폴리테트라메틸렌 에테르 글리콜(PTMG: Polytetramethylene ether glycol) 및 폴리에스테르 디올(Polyester diol)로 이루어진 군으로부터 선택된 중 하나 이상일 수 있다. Here, the polyol may contain hydroxy groups at both ends. For example, the polyol is one selected from the group consisting of polycarbonate diol, polycaprolacton diol, polytetramethylene ether glycol (PTMG), and polyester diol. It could be more than that.
또한, 이소시아네이트는 양 말단에 이소시아네이트기를 가지는 것일 수 있으며, 이소시아네이트로 TDI(Toluene diisocyanate)나 MDI(Methylene diphenyl diisocyanate) 등을 이용할 수 있다.Additionally, the isocyanate may have isocyanate groups at both ends, and TDI (Toluene diisocyanate) or MDI (Methylene diphenyl diisocyanate) may be used as the isocyanate.
여기서, 하이브리드 폴리우레아 바인더를 생성하기 위하여, 먼저 폴리올에 아민을 첨가하여 혼합물을 생성할 수 있으며, 이후 혼합물에 이소시아네이트를 첨가하여 하이브리드 폴리우레아 바인더를 생성할 수 있다. 이 경우, 혼합물에 포함된 폴리올은 이소시아네이트와 우레탄 결합(urethane bond)을 형성하고, 혼합물에 포함된 아민은 이소시아네이트와 우레아 결합(Urea bond)을 형성할 수 있다. 즉, 혼합물과 이소시아네이트 사이의 반응에 의하여, 우레탄 결합과 우레아 결합이 하이브리드 형태로 형성된 하이브리드 폴리우레아 바인더를 생성하는 것이 가능하다. 본 발명의 일 실시예에 의한 하이브리드 폴리우레아 바인더를 이용하면, 기존의 폴리우레탄 바인더에 비하여 탄성포장재의 인장강도 및 신장율을 향상시킬 수 있으며, 우수한 내수성에 의하여 탄성포장재의 물놀이용 바닥재로서의 기능성도 향상시킬 수 있다. Here, in order to create a hybrid polyurea binder, an amine can first be added to polyol to create a mixture, and then isocyanate can be added to the mixture to create a hybrid polyurea binder. In this case, the polyol contained in the mixture may form a urethane bond with the isocyanate, and the amine contained in the mixture may form a urea bond with the isocyanate. That is, it is possible to produce a hybrid polyurea binder in which a urethane bond and a urea bond are formed in a hybrid form by reaction between the mixture and the isocyanate. By using the hybrid polyurea binder according to an embodiment of the present invention, the tensile strength and elongation of the elastic packaging material can be improved compared to the existing polyurethane binder, and the functionality of the elastic packaging material as a flooring material for water play is also improved due to excellent water resistance. You can do it.
실시예에 따라서는, 폴리올과 MDI의 우레탄 반응으로 MDI를 95% 정도 소모하고, 나머지 5%의 MDI로 아민과 우레아 반응을 수행하여, 하이브리드 폴리우레아 바인더를 생성하는 것도 가능하다.Depending on the embodiment, it is possible to produce a hybrid polyurea binder by consuming about 95% of the MDI through a urethane reaction between polyol and MDI, and then performing an amine and urea reaction with the remaining 5% of MDI.
탄성포장재 형성단계(S20)에서는, 하이브리드 폴리우레아 바인더와 고무분말을 혼합하여 탄성포장재를 형성할 수 있다(S20). 이때, 고무분말 1 중량부에 하이브리드 폴리우레아 바인더는 0.2 중량부로 혼합하여 탄성포장재를 형성할 수 있으며, 생성된 탄성포장재는 이후 콘크리트로 형성된 기층 등에 포설할 수 있다. In the elastic packaging material forming step (S20), the elastic packaging material can be formed by mixing a hybrid polyurea binder and rubber powder (S20). At this time, 0.2 parts by weight of hybrid polyurea binder can be mixed with 1 part by weight of rubber powder to form an elastic packaging material, and the resulting elastic packaging material can then be installed on a base layer formed of concrete.
여기서, 고무분말은 EPDM(Ethylene Propylene diene Monomer rubber)과 천연고무(NR: Natural Rubber)가 혼합된 것일 수 있으며, EPDM과 NR의 혼합비율은 8:2일 수 있다. 즉, EPDM과 NR을 각각 80중량%와 20중량%로 혼합할 수 있으며, 이 경우, EPDM만을 사용하는 경우에 비하여 탄성을 높이는 효과를 얻을 수 있다. Here, the rubber powder may be a mixture of Ethylene Propylene diene Monomer rubber (EPDM) and Natural Rubber (NR), and the mixing ratio of EPDM and NR may be 8:2. That is, EPDM and NR can be mixed at 80% by weight and 20% by weight, respectively, and in this case, the effect of increasing elasticity can be obtained compared to the case of using only EPDM.
EPDM은 에틸렌(Ethylene), 프로필렌(Propylene Rubber), 비공역 디엔(Non-conjugated Diene) 등을 포함하는 합성 고무일 수 있으며, 내오존성과 내한성, 내열성, 내용재성이 뛰어나고 양호한 안전성을 가질 수 있다. 또한, EPDM을 이용하면 탄성포장재의 색상과 패턴을 다양하게 구현하는 것이 가능하다.EPDM may be a synthetic rubber containing ethylene, propylene rubber, non-conjugated diene, etc., and has excellent ozone resistance, cold resistance, heat resistance, and solvent resistance and good safety. In addition, using EPDM, it is possible to implement a variety of colors and patterns of elastic packaging materials.
고무분말은 EPDM과 NR을 상호 간에 가압 또는 가온하여 결합한 것일 수 있으며, 실시예에 따라서는 고무분말의 입경을 2~3mm 등 미리 설정된 범위로 제한하는 것도 가능하다.Rubber powder may be a combination of EPDM and NR by pressing or heating each other, and depending on the embodiment, it is possible to limit the particle size of the rubber powder to a preset range such as 2 to 3 mm.
한편, 실시예에 따라서는, 고무분말에 N-할라민(halamine) 조성물을 더 포함하여 탄성포장재를 형성하는 것도 가능하다. 즉, 미생물에 대한 항균 활성이 우수한 N-할라민 조성물을 고무분말에 배합한 후, 하이브리드 폴리우레아 바인더에 혼합하여 탄성포장재를 생성할 수 있다. 여기서, N-할라민 조성물은 질소와 할로겐 사이에 하나 이상의 공유결합을 갖는 아민, 아마이드 또는 이미드 구조를 갖는 물질로, 할로겐 원소, 예를들어 염소를 유리시키는 경우 항균 능력을 나타낼 수 있다. 일례로 N-할라민은 히단토인(Hydantoin), 옥사졸리돈 (oxazolodinone), 이미다졸리디논 (imldazolidinone), 시아누르산 (cyanuric acid)이 가능하다. 따라서, 고무분말에 N-할라민 조성물을 혼합한 후 성형하거나, 탄성포장재의 표면을 N-할라민으로 코팅하는 등의 방식으로 탄성포장재에 N-할라민 조성물을 포함시킬 수 있다. 이 경우, 탄성포장재 내에는 N-할라민으로부터 유리되는 할로겐(즉 Cl*) 성분이 함유될 수 있으며, 이에 따라 탄성포장재 내의 미생물 증식을 방지할 수 있다. Meanwhile, depending on the embodiment, it is also possible to form an elastic packaging material by further including an N-halamine composition in the rubber powder. That is, an N-halamine composition with excellent antibacterial activity against microorganisms can be mixed with rubber powder and then mixed with a hybrid polyurea binder to produce an elastic packaging material. Here, the N-halamine composition is a material having an amine, amide, or imide structure with one or more covalent bonds between nitrogen and halogen, and can exhibit antibacterial ability when liberating a halogen element, for example, chlorine. For example, N-halamine may include hydantoin, oxazolidinone, imidazolidinone, and cyanuric acid. Therefore, the N-halamine composition can be included in the elastic packaging material by mixing the N-halamine composition with rubber powder and then molding it, or coating the surface of the elastic packaging material with N-halamine. In this case, the elastic packaging material may contain a halogen (i.e. Cl * ) component released from N-halamine, thereby preventing the growth of microorganisms in the elastic packaging material.
코팅단계(S30)에서는, N-할라민 조성물을 재생시키는 재생물질을 탄성포장재의 상부에 코팅할 수 있다. 일반적으로, 탄성포장재에 포함된 N-할라민 조성물은 할로겐 원자(염소 원자)가 소모됨에 따라 그 항균력을 상실하게 된다. 다만, N-할라민이 다시 할로겐 원자(염소 원자)를 보충할 수 있도록 재생물질로 처리하면 항균 능력을 회복할 수 있다. 여기서, 재생물질은 할라민을 염소화할 수 있는 물질이라면 제한없이 사용할 수 있으며, 대표적으로 NaOCl, CaOCl2, CaCl2 또는 이들의 혼합물을 상기 재생물질로 사용할 수 있다. 따라서, 본 발명의 일 실시예에 의한 탄성포장재는, 내부에 N-할라민 조성물을 재생하기 위한 재생물질을 더 포함하여, 탄성포장재의 항균 기능을 연장시킬 수 있다. 구체적으로, 재생물질을 탄성포장재의 상부에 미리 설정한 두께로 코팅할 수 있다. 이 경우, 비가 오거나 물이 뿌려지면, 탄성포장재의 상부에 위치한 재생물질이 물에 녹을 수 있으며, 물에 녹은 재생물질이 N-할라민에게 할로겐 원자를 공급할 수 있다. 이외에도, 재생물질의 블록을 탄성포장재 내부에 일정한 간격으로 위치시키는 등 다양한 방식으로 N-할라민 조성물을 재생시킬 수 있다.In the coating step (S30), the regenerated material that regenerates the N-halamine composition can be coated on the top of the elastic packaging material. In general, the N-halamine composition contained in the elastic packaging material loses its antibacterial activity as the halogen atoms (chlorine atoms) are consumed. However, the antibacterial ability can be restored if N-halamine is treated with a regenerated material so that it can replenish halogen atoms (chlorine atoms). Here, the regenerated material can be used without limitation as long as it is a material that can chlorine halamine. Typically, NaOCl, CaOCl 2 , CaCl 2 or a mixture thereof can be used as the regenerated material. Therefore, the elastic packaging material according to an embodiment of the present invention can further include a recyclable material for regenerating the N-halamine composition therein, thereby extending the antibacterial function of the elastic packaging material. Specifically, the recycled material can be coated on the top of the elastic packaging material at a preset thickness. In this case, if it rains or is sprayed with water, the recycled material located on the top of the elastic packaging material may dissolve in water, and the recycled material dissolved in water may supply halogen atoms to N-halamine. In addition, the N-halamine composition can be recycled in various ways, such as placing blocks of recycled material at regular intervals inside the elastic packaging material.

The elastic packaging material according to an embodiment of the present invention can be manufactured by the above-described elastic packaging material manufacturing method. For example, the elastic packaging material is a hybrid polyurea binder formed by mixing 60% by weight of polyol containing a hydroxy group, 25% by weight of isocyanate containing an isocyanate group, 10% by weight of solvent, and 5% by weight of amine, and rubber powder. It may have been formed.
실시예에 따라서는, 하이브리드 폴리우레아 바인더와 고무분말에, N-할라민 조성물을 더 혼합하여 탄성포장재를 생성하는 것도 가능하다. 이 경우, 탄성포장재를 콘크리트 등의 기층에 포설한 이후, 탄성포장재의 상부에 N-할라민 조성물을 재생시키는 재생물질을 코팅시킬 수 있다.Depending on the embodiment, it is also possible to produce an elastic packaging material by further mixing the N-halamine composition with the hybrid polyurea binder and rubber powder. In this case, after laying the elastic packaging material on a base layer such as concrete, a regenerative material that regenerates the N-halamine composition can be coated on the top of the elastic packaging material.
