그러나, 상기 등록특허를 비롯한 종래의 모든 기술사상에 의하면 인조잔디 매트의 배면코팅재 종류가 주로 라텍스와 폴리우레탄, 폴리에틸렌인데 그 중 라텍스 코팅재의 경우에는 강한 접착력과 인발력을 발휘하는데 문제점이 있어왔고, 비, 눈, 고온, 저온 등의 장시간 기후조건에 노출됨으로 인해 그 인발력의 저하가 문제시 되어 왔으며, 고무화학제품 특유의 냄새로 인해 인조잔디 사용자의 피로감을 줄이는데 한계가 지적되고 있다. 또한, 인조잔디가 사용수명에 도달한 경우 폐기시 재활용이 어려운 문제점들을 내포하고 있다.However, according to all the conventional arts including the above-mentioned registered patents, the type of the back coating material of artificial turf mat is mainly latex, polyurethane, polyethylene, among which latex coating materials have problems in exhibiting strong adhesive force and pulling force, , Snow, high temperature, low temperature, etc., and it has been pointed out that there is a limit to reduce the fatigue of users of artificial turf due to the peculiar smell of rubber chemical products. In addition, when artificial turf reaches the service life, it has difficulties in recycling at the time of disposal.
반면, 폴리우레탄의 경우 장시간의 기후조건에서도 내구성을 발휘하는 장점은 있으나 가격이 비싸서 보편적으로 사용할 수 없는 것이 가장 큰 문제점이었다.On the other hand, polyurethane has the advantage of exhibiting durability even under long climatic conditions, but the most problem is that it is not universally usable because it is expensive.
또한, 폴리에틸렌의 경우에는 폴리우레탄에 비해 접착성능이 약해 인발력이 저하되는 문제가 있었다.Further, in the case of polyethylene, the adhesive performance is weaker than that of polyurethane, and the pulling force is lowered.
따라서, 날로 증가하고 있는 인조잔디의 보급량과 인조잔디 사용자의 증가에 따라 인조잔디의 친환경성과 내구성을 증가시킬 수 있는 개선된 인조잔디가 요구되고 있다. Therefore, there is a demand for improved artificial turf that can increase the environmental friendliness and durability of artificial turf according to the increasing amount of artificial turf that is increasing day by day and the increase of artificial turf users.

이하, 첨부된 도면들 및 후술 되어 있는 내용을 참조하여 본 발명의 바람직한 실시예들을 상세히 설명한다. 그러나, 본 발명은 여기서 설명되는 실시예들에 한정되지 않고 다른 형태로 구체화될 수도 있다. 오히려, 여기서 소개되는 실시예들은 개시된 내용이 철저하고 완전해질 수 있도록 그리고 당업자에게 본 발명의 기술적 사상이 충분히 전달될 수 있도록 하기 위해 제공되어 지는 것이다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings and the following description. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
도 1은 본 발명에 따른 친환경 인조잔디 매트의 일실시예를 도시하는 단면도이다.1 is a cross-sectional view illustrating an embodiment of an environmentally friendly artificial turf mat according to the present invention.
도 1을 참조하면, 본 발명에 따른 친환경 인조잔디 매트는 기포지와, 기포지 상에 제직되는 인조잔디 파일과, 상기 기포지 하면에 코팅되는 인조잔디 백코팅(back coating)을 포함할 수 있다.Referring to FIG. 1, the eco-friendly artificial turf mat according to the present invention may include a green paper, a synthetic turf pile woven on a green paper, and a synthetic turf back coating coated on the green paper .
본 발명에 따른 인조잔디 백코팅은 폴리올레핀계 수지 100중량부와, TEOS(Tetraethoxysilane)로 표면 개질된 나노 실리카 1~10중량부와, 금속 산화물 분말 1~10중량부와, 비스무스(Bi)계 촉매 0.5~5중량부를 포함할 수 있다.The artificial turf back coating according to the present invention comprises 100 parts by weight of a polyolefin resin, 1 to 10 parts by weight of nanosilica surface-modified with TEOS (tetraethoxysilane), 1 to 10 parts by weight of a metal oxide powder, 0.5 to 5 parts by weight.
상기 폴리올레핀계 수지는 폴리에틸렌을 단독으로 사용할 수도 있고, 폴리프로필렌이 폴리에틸렌 대비 10~30중량%로 혼합된 것을 예시할 수 있는데, 상기 폴리프로필렌를 첨가하지 않은 것에 비해 접착력과 탄성율을 증가시킬 수 있는 장점이 있으며, 10중량% 미만으로 미만인 경우에는 상술한 효과를 기대하기 어렵고, 30중량%를 초과하는 경우에는 내산성, 내알칼리성, 내약품성, 내충격성 등 폴리에틸렌 고유의 특성이 저하될 수 있으므로, 상기 범위로 제한하는 것이 바람직하다.The polyolefin-based resin may be used alone or in combination of 10 to 30% by weight of polypropylene with respect to polyethylene. The polyolefin-based resin may be advantageous in that the adhesive strength and the modulus of elasticity can be increased If the content is less than 10% by weight, the above-mentioned effects are unlikely to be achieved. When the content is more than 30% by weight, characteristics inherent to polyethylenes such as acid resistance, alkali resistance, chemical resistance and impact resistance may deteriorate. .
상기 TEOS(Tetraethoxysilane)로 표면 개질된 나노 실리카는 소수성, 내수성 등의 특성을 부여하여 장기간 사용에도 물성 저하를 방지할 수 있으며, 상기 폴리올레핀계 수지의 접착력을 극대화하여 인발력을 향상시킬 뿐만 아니라, 내마모성 등의 물성 향상에도 기여한다.The nanosilica surface-modified with TEOS (Tetraethoxysilane) imparts properties such as hydrophobicity and water resistance to prevent property deterioration even after long-term use. In addition to improving the pulling force by maximizing the adhesion of the polyolefin resin, Thereby contributing to the improvement of the physical properties.
상기 TEOS(Tetraethoxysilane)로 표면 개질된 나노 실리카는 평균 입경이 10~100nm인 나노 실리카 100중량부를 기준으로 TEOS(Tetraethoxysilane) 10~30중량부를 혼합하여 제조하는 것을 예시할 수 있다.The nanosilica surface-modified with TEOS (tetraethoxysilane) may be prepared by mixing 10 to 30 parts by weight of TEOS (tetraethoxysilane) based on 100 parts by weight of nano silica having an average particle diameter of 10 to 100 nm.
금속 산화물 분말은 10~100 마이크로 평균 입경을 가지는 WO3, Cu2O, CuO, FeO, CoO, ZrO2, Sc2O3, TiO2, 중 적어도 어느 하나인 것을 예시할 수 있다.The metal oxide powder may be at least one of WO 3 , Cu 2 O, CuO, FeO, CoO, ZrO 2 , Sc 2 O 3 and TiO 2 having a micro average particle diameter of 10 to 100 μm.
상기 금속 산화물 분말은 내 마모성을 향상시켜주고, 그 중 TiO2, WO3 등은 광촉매 역할도 수행하게 된다.The metal oxide powder improves abrasion resistance, and TiO 2 , WO 3 Etc. also act as a photocatalyst.
상기 금속 산화물 분말이 1중량부 미만이면, 그 함량이 0.1중량부 미만이면 상술한 작용을 수행하기 어렵고, 10중량부를 초과하면 오히려 인발력 감소의 원인이 되므로, 상기 범위로 제한하는 것이 바람직하다.If the content of the metal oxide powder is less than 1 part by weight, it is difficult to carry out the above-mentioned action if the content is less than 0.1 part by weight. If it exceeds 10 parts by weight, it is preferable to restrict the above range.
상기 비스무스(Bi)계 촉매는 친환경 인조잔디 백코팅 조성물의 경화 시간을 단축시키고, 내수성 및 내마모성 등의 물성을 향상시키는 역할을 하는 것으로서, 적어도 0.5중량부를 함유하여야 상술한 효과를 기대할 수 있으며, 5중량부를 초과하더라도 상술한 효과의 증가 폭이 미미하여 비효율적이다.The bismuth (Bi) -based catalyst serves to shorten the curing time of the artificial turf back coating composition and improve physical properties such as water resistance and abrasion resistance, and it is expected that the above-mentioned effect can be expected by containing at least 0.5 part by weight. Even if it exceeds the weight part, the increase in the above-mentioned effect is insignificant, which is inefficient.
상기 비스무스(Bi)계 촉매는 비스무스(Bi)와 Bi2O3가 1 : 0.1~0.3중량비로 혼합된 것을 사용할 수도 있다.The bismuth (Bi) based catalyst may be a mixture of bismuth (Bi) and Bi 2 O 3 in a weight ratio of 1: 0.1 to 0.3.
그리고 비스무스가 10~100nm의 평균 입경을 가진 Bi2O3와 함께 사용되는 경우에는 경화 시간 단축에 대한 상승 효과를 기대할 수 있으며, 추가적으로 자외선 내지 방사선 등을 차단 역할도 수행하므로, 별도의 자외선 차단제 투입 없이도 자외선에 의한 백코팅의 접착력 등의 물성 저하를 방지할 수 있다.When bismuth is used together with Bi 2 O 3 having an average particle size of 10 to 100 nm, a synergistic effect for shortening the curing time can be expected. In addition, since it also acts to block ultraviolet rays or radiation, It is possible to prevent deterioration of physical properties such as adhesion of back coating by ultraviolet rays.
여기서 Bi2O3가 0.1중량비 미만으로 혼합되는 경우에는 상술한 물성 저하 효과를 기대하기 어렵고, 0.3중량비를 초과하는 경우에는 비스무스에 의한 촉매 작용이 저하될 수 있으므로, 상기 중량비로 제한하는 것이 바람직하다.When the content of Bi 2 O 3 is less than 0.1 wt%, it is difficult to expect the effect of lowering the physical properties described above. If it exceeds 0.3 wt%, the catalytic activity due to bismuth may be lowered. .
상기 나노 사이즈의 Bi2O3 분말은 금속 전구체를 액상에서 환원제를 이용하여 환원시켜 제조할 수 있다.The nano-sized Bi 2 O 3 The powder can be prepared by reducing a metal precursor in a liquid phase using a reducing agent.
상기 금속 전구체는 금속 수소화물(metal hydride), 금속 수산화물(metal hydroxide), 금속 황산화물(metal sulfide), 금속 질산화물(metal nitrate), 금속 질화물(metalnitride), 금속 할로겐화물(metal halide), 금속 알킬화합물, 금속 아릴화합물, 이들의 착화합물(coordination compound) 또는 이들의 조합인 것을 예시할 수 있으며, 금속 전구체 원료 물질은 비스무스(Bi)이다.The metal precursor may be a metal hydride, a metal hydroxide, a metal sulfide, a metal nitrate, a metal nitride, a metal halide, a metal alkyl A metal aryl compound, a coordination compound thereof, or a combination thereof, and the metal precursor raw material is bismuth (Bi).
상기 환원제는 수산화나트륨(NaOH2), 리튬보로하이드라이드(LiBH4), 소듐보로하이드라이드(NaBH4), 포타슘보로하이드라이드 (KBH4), 리튬알루미늄하이드라이드(LiAlH4), 소듐알루미늄하이드라이드(NaAlH4), 포타슘알루미늄하이드라이드(KAlH4) 또는 이들의 조합인 것을 예시할 수 있다.The reducing agent is sodium hydroxide (NaOH 2), lithium view it hydride (LiBH 4), sodium view it hydride (NaBH 4), potassium view it hydride (KBH 4), lithium aluminum hydride (LiAlH 4), sodium Aluminum hydride (NaAlH 4 ), potassium aluminum hydride (KAlH 4 ), or a combination thereof.
본 발명의 친환경 인조잔디 백코팅 조성물에는 오염방지제를 더 포함할 수 있는데, 상기 오염방지제는 불화 아크릴레이트, 불화 메타크릴레이트 및 불화 에틸렌 중에서 하나 선택되는 불화물인 것이 바람직하다.The eco-friendly turf back coating composition of the present invention may further comprise a antifouling agent, which is preferably a fluoride selected from among fluoroacrylate, methacrylate, and ethylene fluoride.
상기 불화물은 분자간의 인력이 작고 표면 에너지가 낮은 성질을 가지고 있어, 방오성은 물론, 발수, 발유 효과도 기대할 수 있다.The fluoride has a small attractive force between molecules and a low surface energy, so that not only antifouling property but also water repellency and oiling effect can be expected.
상기 불화물은 폴리올레핀계 수지 100중량부를 기준으로 0.5~5중량부 범위 내에서 첨가되는 것을 예시할 수 있다.The fluoride may be added in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the polyolefin-based resin.
한편, 본 발명의 인조잔디 백코팅 조성물은 인조잔디 기포지에 250 ~ 450g/㎡의 적은 양으로 코팅하더라도 우수한 접착성능을 유지할 수 있어 제조원가를 절감할 수 있다.On the other hand, the artificial grass back coating composition of the present invention can maintain excellent adhesive performance even when coated with artificial turf base paper in a small amount of 250 to 450 g / m < 2 >
