It relates to an artificial turf excellent elastic filler composition.

인조잔디는 일반잔디에 비하여 초기 시공비가 많이 들지만 거의 반영구적 사용이 가능하고 유지관리의 편의성, 표면을 고르게 형성하여 운동하기 좋은 상태로 형성할 수 있는 등의 이유로 그 선호도가 높은 편이다.The artificial turf has a higher initial preference than the general grass, but it has a high preference because it can be used semi-permanently and can be easily maintained, and the surface can be formed evenly.

인조잔디 구조체는 하부기층 상부에 인조잔디 파일을 고정시키는 파일고정패드층이 형성되며, 파일고정패드층은 기포지와 배킹부로 이루어져 있다. 파일고정패드층 상부에는 규사충진재층이 형성되고 규사충진재층 상부에는 탄성 충진재층이 형성되게 된다. 약 45~65mm 길이의 인조잔디 파일 사이에 규사 등 중량재를 충진시킴으로써 인조잔디 파일을 안정시키게 되며, 규사충진재층 상부에 직경이 약 0.8~2.0mm의 탄성칩을 충진하여 충격을 흡수하도록 구성된다.
The artificial turf structure has a pile fixing pad layer for fixing the artificial turf pile on the lower base layer, and the pile fixing pad layer is composed of a pile fixing part and a backing part. A silica sand filler layer is formed on the upper part of the pile fixing pad layer and an elastic filler layer is formed on the silica sand filler layer. The artificial turf files are stabilized by filling the wefts or the like between the artificial turf piles having a length of about 45 to 65 mm and the elastic turf piles are stabilized and the elastic cushion having a diameter of about 0.8 to 2.0 mm is filled in the upper part of the diaphragm filler layer to absorb the impact .

인조잔디 구조체의 맨 상층에 해당하는 탄성 충진재층은 피부와 접할 수 있는 층이어서 친환경적일 것이 요구되고 있으며, 또한 종래 인조잔디가 여름철에는 그 표면온도가 약 섭씨 70도까지 상승하고 있어 인조잔디 사이에 형성되는 탄성충진재층이 인조잔디의 온도상승을 어느 정도 저지할 수 있을 것이 요구되고 있다.
The elastic filler layer corresponding to the uppermost layer of the artificial turf structure is required to be environmentally friendly because it is a layer that can be in contact with the skin. Also, in the summer, the artificial turf has a surface temperature of about 70 degrees centigrade It is required that the formed elastic filler layer can prevent the temperature rise of artificial turf to some extent.

종래기술로서 등록특허 제10-1163051호에 탄산칼슘, 규사 중 하나 이상을 포함하는 중량재 20~60 중량%, 왕겨, 톱밥, 코코피아, 코이어, 천연섬유, 피트, 피트모스, 코르크 중 하나 이상을 포함하는 첨가재 19~59 중량%, 천연고무, 합성고무, 우레탄, 합성수지 중 하나 이상을 포함하는 접착제 10~30 중량%, 안료 0.5~3.0 중량%의 비율로 배합되어 이루어진 인조잔디용 탄성칩 충진제 조성물이 공지되어 있다. 이러한 종래기술의 충진재 조성물은 천연재료를 일부 사용하고는 있으나 온도상승을 차단하는 기능은 미흡한 것이었다.
As a prior art, Patent No. 10-1163051 discloses a method for producing a steel sheet comprising 20 to 60% by weight of a weight material containing at least one of calcium carbonate and silica sand, at least one of chaff, sawdust, cocopia, coir, natural fiber, Of an additive containing 19 to 59% by weight of an additive containing at least one of a natural rubber, a synthetic rubber, a urethane and a synthetic resin, and 0.5 to 3.0% by weight of a pigment, Compositions are known. The filler composition of this prior art is partially using natural materials, but the function of blocking temperature rise is insufficient.

따라서 환경친화적이면서 동시에 태양광에 의한 인조잔디의 온도상승을 어느정도 저지할 수 있는 종래보다 개선된 인조잔디용 탄성 충진재가 요망되고 있다.Therefore, there is a demand for an improved synthetic filler for artificial turf which is eco-friendly and which can prevent temperature rise of artificial turf caused by sunlight to some extent.

본 발명은 환경친화적이면서 동시에 종래기술에 비해 태양광에 의한 인조잔디 온도상승을 저지할 수 있는 개선된 인조잔디용 탄성 충진재 조성물을 목적으로 한다.An object of the present invention is to provide an improved elastic filler composition for artificial turf which is eco-friendly and which can prevent the artificial turf temperature rise by sunlight as compared with the prior art.

이러한 목적을 달성하기 위하여, 본 발명은 송진 1.5~14.0중량%, 무기질안료 0.5~2.5중량%, 미가황 천연고무 30.0~40.0중량%, 폴리에틸렌수지 또는 폴리프로필렌수지 중에서 선택된 1종 이상의 폴리머수지 8.0~10.0중량%, 탈크, 탄산칼슘, 프로세스오일 중에서 선택된 1종 이상의 충전제(filler) 30.0~45.0중량%, 가교제2.0~2.5중량%, 윤활제 1.0~2.3중량%, 착색제1.0~2.0중량%로 구성되는 것을 특징으로 하는 인조잔디용 탄성 충진재 조성물에 관한 것이다.
In order to achieve the above object, the present invention provides a method for producing a polyester resin composition, comprising the steps of: providing a resin composition comprising 1.5 to 14.0% by weight of rosin, 0.5 to 2.5% by weight of an inorganic pigment, 30.0 to 40.0% by weight of unvulcanized natural rubber, By weight of a crosslinking agent, 1.0 to 2.3% by weight of a lubricant and 1.0 to 2.0% by weight of a colorant, based on 100% by weight of a filler selected from the group consisting of talc, calcium carbonate and process oil, To an elastic filler composition for artificial turf.

태양광의 자외선과 적외선은 흡수 및 반사에 의해 인조잔디에 흡수되어 인조잔디의 온도를 상승시키게 되며, 여름철에는 약 섭씨 70도까지 상승하여 피부에 닿으면 화상을 입힐 정도가 된다. 본 발명의 상기 조성물로 제조된 탄성충진재는 충진재에 입사된 태양광의 재반사를 차단하여 인조잔디의 온도 상승을 저지하는 것으로 나타났으며, 종래기술에 비해 약 30% 정도 온조 저하기능이 있는 것으로 나타났다.
The sun's ultraviolet and infrared rays are absorbed by artificial turf by absorption and reflection, raising the temperature of artificial turf. In the summer, it rises to about 70 degrees Celsius, which causes burns to the skin. The elastic filler made of the composition of the present invention has been shown to block the reflection of sunlight incident on the filler to prevent the temperature rise of the artificial turf and has a function of lowering the temperature of about 30% .

또한 본 발명은 목재분말, 코르크분말, 송진 등의 천연재료를 포함하도록 함으로써 인체와의 접촉에서 부작용을 감소시킨 것이다.Further, the present invention includes natural materials such as wood powder, cork powder, and rosin, thereby reducing adverse effects in contact with the human body.

본 발명의 인조잔디용 탄성 충진재 조성물로 만든 탄성칩 충진제층은 온도상승을 차단하는 기능이 현저히 개선되고 동시에 환경친화적인 탄성충진재를 제공할 수 있도록 하는 효과가 있으며, 더 구체적으로는 여름철 종래 인조잔디 표면온도가 약 섭씨 70도까지 상승하였던 것을 본 발명의 인조잔디 파일에 의해 약 섭씨 55~60도 정도까지 30% 정도 열차단의 효과가 있었다.The elastic chip filler layer made of the synthetic filler composition for artificial turf of the present invention has an effect of significantly improving the function of shutting off the temperature rise and at the same time providing an environmentally friendly elastic filler. More specifically, The surface temperature was increased to about 70 degrees Celsius by the artificial turf pile of the present invention.
