Description
본 발명은 인조잔디용 충진재의 조성물에 관한 것으로서, 보다 상세하게는 재생원료인 폐 PVB(Polyvinyl butyral), SEBS(Styrene-EthyeneButyrene-styrene)분말, 가축분뇨를 가공한 바이오매스 분말, 탄산칼슘 또는 탈크를 열혼합한 다음 압출 및 펠릿형태로 성형하여 인조잔디용 충진재로 사용함으로써 친환경성과 내연성 강화와 충격에 의해 부스러짐을 완화시켜주는 인조잔디용 충진재 조성물에 관한 것이다. The present invention relates to a composition of a filler for artificial turf, and more particularly, recycled raw material waste PVB (Polyvinyl butyral), SEBS (Styrene-EthyeneButyrene-styrene) powder, biomass powder processed from livestock manure, calcium carbonate or talc It relates to a filler composition for artificial turf, which is heat-mixed, then extruded and molded into pellets, and used as a filler for artificial turf, thereby reinforcing eco-friendliness and flame resistance and mitigating crumbling by impact.
야구장, 축구장 등에는 먼지의 발생을 방지하기 위하여 천연잔디가 설치되었으나, 천연잔디는 비용이 많이 들며관리가 어려워 최근에는 천연잔디의 감촉을 지니면서 오래 사용할 수 있고 유지비가 적게 드는 인조잔디의 설치가 증가되고 있다.Natural turf was installed in baseball fields and soccer fields to prevent dust generation, but natural turf is expensive and difficult to manage. is increasing
일반적으로 인조잔디는 복수가닥의 필라멘트사에 의해 잔디층이 형성된 인조잔디 구조체와, 상기 인조잔디 구조체의 필라멘트사 사이에 충전되는 충진재로 이루어져 있으며, 충진재로는 폐타이어를 파쇄한 SBR칩(Styrene Butadiene Rubber)이나 EPDM칩(ethylene propylene diene monomer)이 널리 사용되고 있다.In general, artificial turf consists of an artificial turf structure in which a turf layer is formed by a plurality of filament yarns, and a filler filled between the filament yarns of the artificial turf structure. Rubber) or EPDM chip (ethylene propylene diene monomer) is widely used.
그러나 상기와 같은 폐타이어 고무칩은 검은색을 띠고 있기 때문에 태양광을 흡수하여 구장의 온도를 상승시키므로 운동환경을 악화시킬 뿐 아니라, 기온이 섭씨 30℃를 넘어가는 여름이면 고무칩에서 매캐한 냄새가 발생하며 뜨거운 지열에 녹아내린 고무칩이 달라붙거나 유해가스가 발생되고, 수분 함유량이 적으면서도 많은 마찰열을 발생시켜 이용자가 미끄러질 경우, 화상 위험이 발생되는 문제점이 있었다.However, since the waste tire rubber chips as described above have a black color, they absorb sunlight and raise the temperature of the stadium, which not only worsens the exercise environment, but also causes a musty smell from the rubber chips in summer when the temperature exceeds 30°C. There was a problem in that rubber chips melted in hot geothermal heat stick together or harmful gases are generated, and a lot of frictional heat is generated even though the moisture content is low, so that if the user slips, there is a risk of burns.
특히, 폐타이어 고무칩은 장기간 사용될 경우, 분진이 발생되어 중금속 등의 유해한 성분이 방출될 뿐 아니라, 인조잔디를 사용하는 사용자들의 신발이나 옷에 분진이 묻게 되어, 사용자의 건강을 해치게 되는 문제점이 있었다.In particular, when waste tire rubber chips are used for a long period of time, dust is generated and harmful components such as heavy metals are released, and dust is attached to the shoes and clothes of users who use artificial turf, thereby harming the health of users. there was.
또한, 상기와 같은 폐타이어 고무칩의 문제점을 해소하기 위하여, SEBS 또는 EPDM 고무를 가교시켜 만든 탄성폴리머가 널리 사용되어지고 있으나, 이들 탄성폴리머 역시 인체에 유해한 화학물질이 함유되어 있어, 장기간 또는 고온의 하절기에 화학약품 고유의 냄새나 악취가 발생되는 등 여러가지 문제점이 있었다.In addition, in order to solve the problem of waste tire rubber chips as described above, elastic polymers made by crosslinking SEBS or EPDM rubber are widely used, but these elastic polymers also contain chemicals harmful to the human body. During the summer season, there were various problems such as the smell or odor of chemicals.
또한, 폐타이어 고무칩은 장기간 외부에 노출되고 기후 변화에 따라 외부에서 가해지는 작은 충격에도 쉽게 부서지는 문제점이 있다.In addition, waste tire rubber chips have a problem in that they are exposed to the outside for a long time and are easily broken even by a small impact applied from the outside according to climate change.
또한, SEBS 또는 NBR(니트릴부타디엔 고무)로 인조잔디용 충진재를 생산하면 제조원가가 상승하고, EPDM이나 EVA만으로 생산하면 충진재가 잘 부셔져 유실됨으로 내구성이 약한 문제점이 있으며 제조원가가 상승하는 문제점이 있다.In addition, when the filler for artificial turf is produced with SEBS or NBR (nitrile butadiene rubber), the manufacturing cost rises, and when produced only with EPDM or EVA, the filler is easily broken and lost, so there is a problem that the durability is weak, and there is a problem that the manufacturing cost rises.

The filler (1) for artificial turf of the present invention is 1 to 15 parts by weight of SEBS (Styrene-EthyeneButyrene-styrene) powder, 1 to 20 parts by weight of biomass powder composed of livestock manure, in 100 parts by weight of waste PVB (Polyvinyl butyral), which is a renewable raw material. , It is characterized in that a composition in which 50 to 100 parts by weight of calcium carbonate or talc is selected as a filler is mixed with heat, compressed, and then cut and pelletized.
상기 재생원료인 폐 PVB(Polyvinyl Butyral)은 폴리비닐 알콜과 부틸알데히드의 응결반응으로 형성되는 것으로서, 뛰어난 수지내 결합력과 소재 표면과의 뛰어난 부착력, 유연성을 가진 뛰어난 강인성 및 광학적 투명성의 유용성이 인정되고 있다.The recycled raw material waste PVB (Polyvinyl Butyral) is formed by the condensation reaction of polyvinyl alcohol and butyraldehyde. have.
상기 폐 PVB는 폐 전면 유리에서 필름형태인 폐 PVB를 분리한 후 전처리하여 사용하는게 바람직하나, 이에 한정되지 않고, 필름형태인 폐 PVB는 차량의 폐 전면 유리 이외에도 PVB가 포함된 유리라면 어느 것에서나 재활용될 수 있다.The waste PVB is preferably pre-treated after separating the waste PVB in the form of a film from the waste windshield, but is not limited thereto. can be recycled.
상기 폐 PVB는 유리와 필름을 선별하는 일반적인 상용화 장비를 이용하여 분리할 수 있다.The waste PVB can be separated using a general commercial equipment for sorting glass and film.
자동차의 폐 전면유리에서 폐 PVB를 수거하여 필름이 아닌 액상으로 성형하여 준비하여도 동일한 효과를 얻을 수 있다..The same effect can be obtained even if the waste PVB is collected from the waste windshield of a car and prepared by molding it into a liquid rather than a film.
따라서 재생원료인 폐 PVB에 SEBS 분말 1 내지 15 중량부를 선택하고, 가축분뇨로 이루어진 바이오매스 분말 분말 1 내지 20 중량부를 혼합한다.Therefore, 1 to 15 parts by weight of SEBS powder is selected in the waste PVB, which is a renewable raw material, and 1 to 20 parts by weight of biomass powder consisting of livestock manure is mixed.
상기 바이오매스 분말은 가축분뇨를 톱밥, 미생물배지 및 퇴비부숙용 미생물과 함께 혼합, 교반, 발효, 후숙 및 건조시킨 후 잘게 분쇄하여 마련된 퇴비입자에 항균제를 포함한다.The biomass powder contains an antibacterial agent in compost particles prepared by mixing, stirring, fermenting, ripening and drying livestock manure together with sawdust, microbial medium and composting microorganisms and then crushing them finely.
상기 가축분뇨로서 제조한 퇴비입자는 합성수지등과 혼합하여 각종 산업용기 등을 사출, 압출 또는 성형 등의 소재, 즉 가축분뇨의 활용으로 대기오염, 토양오염 및 수질오염을 해소하고 가축분뇨와 더불어 합성수지의 합체로서 소각시 저탄소를 가능케 한 친환경 저탄소 분해성 항균소재로서 활용토록 하여, 수분 및 충격에 강하고 수명을 보장할 수 있을 뿐만 아니라 소각 내지는 분해시의 환경오염까지 극소화시킬 수 있다.The compost particles manufactured as the livestock manure are mixed with synthetic resins, etc. to eliminate air pollution, soil pollution and water pollution by using materials such as injection, extrusion, or molding of various industrial machines, that is, livestock manure, and synthetic resin with livestock manure. It is used as an eco-friendly, low-carbon, degradable antibacterial material that enables low carbon during incineration.
특히, 가축분뇨를 톱밥, 미생물배지 및 퇴비부숙용 미생물과 함께 혼합, 교반, 발효, 후숙 및 건조시킨 후 잘게분쇄하여 퇴비입자를 마련함으로써 톱밥에 의한 수분흡수를 가능케 하고, 톱밥 및 가축분뇨를 미생물배지 및 퇴비부숙용 미생물과 함께 교반 및 발효시켜 가축분뇨의 적극적인 분해를 실현하면서 후숙 및 건조로서 추가의 발효 및 분해와 더불어 수분까지 제거하여 합성수지와의 용이한 결합을 실현토록 한다.In particular, livestock manure is mixed, stirred, fermented, fermented, and dried together with sawdust, microbial medium and microorganisms for composting, and then finely pulverized to prepare compost particles to enable water absorption by sawdust, and sawdust and livestock manure to microorganisms It realizes active decomposition of livestock manure by stirring and fermenting together with the medium and microorganisms for composting, while further fermentation and decomposition through post-ripening and drying, along with additional fermentation and decomposition, also removes moisture to realize easy bonding with synthetic resins.
