Description

인조잔디 구조체{Artificial turf structure}Artificial turf structure

본 발명은 인조잔디 구조체에 관한 것으로서, 보다 구체적으로는 충진층을 이루는 충진재로부터 인체에 유해한 화학물질이 전혀 검출되지 않아 위생적이며, 배수성 및 습도 유지성이 뛰어나 천연잔디와 유사한 촉감을 나타냄과 동시에 탄성도 뛰어난 인조잔디 구조체에 관한 것이다.The present invention relates to an artificial turf structure, and more specifically, it is hygienic because no harmful chemicals are detected from the fillers forming the filling layer, and is hygienic. It is about excellent artificial turf structure.

통상적으로 인조잔디 구조체는 천연잔디와 유사한 필라멘트들이 돌출되어 있는 합성매트;와 상기 필라멘트들 사이에 충진된 충진재로 이루어진 충진층;으로 구성된다.Typically, the artificial turf structure is composed of a synthetic mat protruding filaments similar to natural grass; and a filler layer made of a filler filled between the filaments.

상기 충진재로는 모래, 탄성 폴리머 또는 이들의 혼합물이 가장 널리 사용되어 왔다.Sand, an elastomer or a mixture thereof has been most widely used as the filler.

상기 탄성 폴리머는 천연고무, 합성고무 또는 열가소성 수지 등이다.The elastic polymer is natural rubber, synthetic rubber or thermoplastic resin.

그러나, 충진재로 탄성 폴리머를 사용하는 경우에는 인조잔디 구조체의 탄성은 향상되지만, 탄성 폴리머로부터 인체에 유해한 화학물질이 배출되어 위생적이지 못하며, 또한 배수성과 습도 유지성도 떨어져 천연잔디와 같이 부드러운 촉감을 발현하기 어려운 문제점이 있었다.However, when the elastic polymer is used as the filler, the elasticity of the artificial turf structure is improved, but chemicals harmful to the human body are discharged from the elastic polymer, which is not sanitary. There was a problem that was difficult to do.

대한민국 출원특허 10-2008-0115058호에서는 열가소성 수지와 황토의 혼합물로 제조된 칩(chip) 형태의 충진재를 사용하는 방법을 제안하고 있으나, 충진재의 일부가 열가소성 수지로 구성되기 때문에 이로 부터 인체에 유해한 화학물질이 배출되는 문제를 해결할수 없었다.Korean Patent Application No. 10-2008-0115058 proposes a method of using a chip-shaped filler made of a mixture of thermoplastic resin and loess, but since some of the filler is composed of thermoplastic resin, it is harmful to human body. The problem of chemical emissions could not be solved.

대한민국 출원특허 10-2006-0136245호에서는 코코넛 칩과 코르크 칩을 접착제에 함침시켜 이를 충진재로 사용하는 방법을 제안하고 있으나, 접착제 사용으로 인해 인체에 유해한 화학물질이 배출되는 문제를 해결할 수 없었다.Korean Patent Application No. 10-2006-0136245 proposes a method of impregnating a coconut chip and a cork chip in an adhesive and using the same as a filler, but a problem in which harmful chemicals are emitted due to the use of the adhesive is not solved.

또 다른 종래기술로는 과립상 코코넛계 식물성 물질과 모래의 혼합물을 인조잔디 구조체의 충진재로 사용하는 방법을 제안하고 있으나, 상기 방법은 코코넛계 식물성 물질이 과립상이기 때문에 필라멘트들 사이에 충진시 위로 떠오르는 충진재의 플로팅(Floating) 현상이 심해지는 문제와, 동절기에 충진층이 동결되는 문제와, 충진재인 코코넛계 식물성 물질이 분해되어 부패되는 문제 등이 있었다.Another conventional technique proposes a method of using a mixture of granular coconut-based vegetable material and sand as a filler for an artificial turf structure, but the method is used when filling between filaments because the coconut-based vegetable material is granular. Floating phenomenon of the rising filler is severe, there is a problem of freezing the filling layer in the winter, and the problem of decomposition and corruption of the coconut-based vegetable material of the filler.

또한 상기와 같이 과립산 코코넛계 식물성 물질과 모래의 혼합물을 충진재로 사용하는 경우, 충진재의 배수성 및 습도 유지성은 우수하나 탄성이 떨어지는 문제가 있었다.In addition, when using a mixture of granulated coconut-based vegetable material and sand as a filler as described above, the drainage and humidity retention of the filler is excellent, but there was a problem of poor elasticity.

지금부터는 필라멘트들 사이에 충진된 충진재가 필라멘트 위로 떠오르는 현상을 "충진재의 플로팅(Floating) 현상"이라고 한다.From now on, the filling of the filler filled between the filaments rises over the filament is called "floating phenomenon of the filler".

본 발명은 충진재로 부터 인체에 유해한 화학물질이 전혀 검출되지 않아 위생적인 인조잔디 구조체를 제공하고자 한다.The present invention is to provide a sanitary artificial turf structure because no harmful chemicals are detected from the filler.

또한, 본 발명은 배수성과 습도 유지성이 우수하여 천연잔디와 같은 촉감을 나타내면서도 탄성이 뛰어나고, 충진재의 플로팅(Floating) 현상이 최소화되고, 동결을 방지할 수 있는 인조잔디 구조체를 제공하고자 한다. In addition, the present invention is to provide an artificial turf structure that is excellent in drainage and humidity retention and excellent in elasticity, while floating in the filling material (minimizing Floating) phenomenon, and can prevent freezing.

이와 같은 과제를 달성하기 위해서 본 발명에서는 충진재로 (ⅰ) 천연 식물성 분말과, (ⅱ) 토사, 규사 또는 이들의 혼합물과, (ⅲ) 천연 동결방지제의 혼합물을 사용하여 인조잔디 구조체의 충진층을 형성함과 동시에 합성매트(1) 이면에 별도의 탄성층(5)을 형성한다.In order to achieve the above object, in the present invention, the filling layer of the artificial turf structure is prepared using a mixture of (i) natural vegetable powder, (ii) earth and sand, silica sand or a mixture thereof, and (iii) a natural cryoprotectant. At the same time, a separate elastic layer 5 is formed on the back surface of the synthetic mat 1.

본 발명은 충진재가 100% 천연물질들로만 구성되어 인체에 유해한 화학물질이 전혀 검출되지 않아 위생적이다.The present invention is hygienic because the filler is composed of only 100% natural substances do not detect any harmful chemicals to the human body.

또한, 본 발명은 충진재 내에 천연 식물성 분말이 포함되어 있기 때문에 배수성과 습도 유지성이 뛰어나 천연잔디와 같은 촉감을 발현함과 동시에 합성매트(1) 이면에 형성된 탄성층(5)으로 인해 탄성이 뛰어나다.In addition, the present invention, because the natural vegetable powder is included in the filler material is excellent in drainage and humidity retention, and exhibits the same feel as the natural grass and at the same time excellent elasticity due to the elastic layer (5) formed on the back of the synthetic mat (1).

또한, 본 발명은 분말형태인 천연 식물성 물질을 사용하기 때문에 충진재의 플로팅(Floating) 현상을 효과적으로 방지할 수 있다.In addition, the present invention can effectively prevent the floating (floating) of the filler because it uses a natural plant material in the form of a powder.
