Description

시트형 탄성포장재 및 이의 제조방법Sheet-type elastic packaging material and manufacturing method thereof
본 발명은 시트형 탄성포장재 및 이의 제조방법에 관한 것으로, 상부층에 적황토가 코팅된 코르크 분말이 포함된 특징이 있어 원적외선 발생에 의한 향균성 효과가 있는 시트형 탄성포장재 및 이의 제조방법에 관한 것이다.The present invention relates to a sheet-type elastic packaging material and a method for manufacturing the same, and to a sheet-type elastic packaging material having an antibacterial effect due to the generation of far-infrared rays because the upper layer contains cork powder coated with red ocher, and to a method for manufacturing the same.
일반적으로 산책로 및 자전거 도로 등은 주민들의 편의성 향상과 건강증진을 위하여 조성한 것으로, 상기 산책로 및 자전거 도로 등은 조경물 및 수목의 사이 양측에 일정폭으로 경계석을 설치하여 산책로는 자연토양을 노출시켜서 산책로 및 자전거 도로를 조성하거나 인위적으로 시공시에는 시멘트로 제조되는 보도블럭을 이용하여 지표면에 연설하여 설치하거나 콘크리트 및 아스콘 등을 이용하여 지표면에 타설하여 형성하는 것이 대부분이다.In general, trails and bicycle paths were created to improve the convenience and health of residents, and for the walkways and bicycle paths, boundary stones were installed on both sides between the landscape and trees to expose the natural soil, thereby exposing the natural soil. When constructing or artificially constructing a bicycle road, most of them are installed by addressing the ground using a sidewalk block made of cement or by pouring it on the ground using concrete or asphalt concrete.
종래의 자연토양을 노출시켜서 되는 산책로 및 자전거도로는 우천시에 흙이 빗물에 씻겨 산책로가 쉽게 망실되어 유지보수가 빈번하게 발생하는 결점이 있고 보도블럭 및 콘크리트와 아스콘 등으로 시공되는 산책로 및 자전거 도로는 내구성이 우수하고 시공이 간편한 잇점은 있으나 이용자가 과실로 넘어지거나 이용자들의 가벼운 충돌에도 신체에 큰 부상이 발생되는 문제점이 있었다.Conventional walking trails and bicycle paths that expose natural soil have a defect in that the soil is washed away in the rain and the trails are easily lost and maintenance occurs frequently. Although it has the advantages of excellent durability and easy construction, there was a problem in that a user accidentally fell or suffered a serious injury to the body even in a light collision of the user.
또한, 상기와 같은 문제점을 해결하기 위하여, 폐타이어를 일정크기로 분쇄한 고무칩과 규사와 접착제를 일정비율로 혼합하여 일정길이와 폭을 갖는 포장재를 성형한 다음, 아스팔트나 콘크리트가 포장된 표면에 접착제를 도포하고, 상기 성형된 포장재를 이중으로 포장하여 이용자들의 안전성을 도모하도록 한 것도 있으나, 상기와 같은 포장재의 설치는 이중포장으로 이루어져야 하므로, 많은 시공시간이 소요되고, 고무칩이 탄성을 제공하므로 분진 또는 냄새가 심하게 발생되며, 폐타이어로부 터 유해물질이 발산되는 문제점이 있었다.In addition, in order to solve the above problems, rubber chips, which are crushed to a certain size, of waste tires, and silica sand and adhesive are mixed in a certain ratio to form a pavement material having a certain length and width, and then the surface on which asphalt or concrete is paved. In some cases, an adhesive is applied to the surface and the molded packaging material is double-packed to promote the safety of users. As a result, dust or odor was generated heavily, and there were problems in that harmful substances were emitted from the waste tires.
또한, 폐타이어나 폐폴리우레탄과 같은 재생 제품의 경우 일부 제품의 경우 중금속을 함유하고 있어, 환경오염이 발생될 뿐 아니라, 시공 후 포장재의 파손현상이 발생되어 미관을 좋지 않게 하는 문제점이 있었다.In addition, in the case of recycled products such as waste tires or waste polyurethane, some products contain heavy metals, which not only causes environmental pollution, but also causes damage to packaging materials after construction, resulting in poor aesthetics.
또한, 상기 포장재 및 보도블록, 콘크리트 등은 모두 자연친화적이지 못하여 공원을 찾는 사람들이 공통적으로 갖는 자연과 보다 친숙하고자 하는 욕구를 충족시키지 못하는 등 여러가지 문제점이 있었다.In addition, the pavement material, sidewalk block, concrete, etc. were all not nature-friendly, so there were various problems such as failing to satisfy the desire to be more familiar with nature that people who visit the park have in common.
관련된 종래기술을 살펴보면, 대한민국공개특허공보 제2005-007217호에는 "발포성 고무칩을 이용한 탄성 포장공법"에 관한 것으로 상기와 같은 탄성 포장공법은 기층 위에 프라이머층(접착층), EPDM 또는 우레탄고무의 발포체를 파쇄한 입자와 바인더로 형성된 발포탄성층, 발포탄층 위에 발포되지 않은 EPDM 또는 우레탄칩과 바인더로 혼합하여 다짐한 표면층으로 적층된 탄성포장공법으로 요약할 수 있는바, 이와 같은 구성으로된 탄성포장공법은 발포탄성층이 형성되어 있어 쿠션성은 우수하다 할 수 있으나 발포층에 의해 지지력이 약하므로 로울러 스케이트나 자전거 등의 순간 멈춤으로 발생하는 전단력에 의해서 쉽게 파단될 수 있는 구성이여서 지지력과 탄성의 적절한 조화가 요구되는 구성이라 할 수 있다.Looking at the related prior art, Korean Patent Application Laid-Open No. 2005-007217 relates to "an elastic packaging method using a foamed rubber chip". It can be summarized as an elastic packaging method in which an elastic foam layer formed of crushed particles and a binder, a non-foamed EPDM or urethane chip and a binder are mixed on the carbon foam layer and laminated as a compacted surface layer. Since silver foamed elastic layer is formed, it can be said that the cushioning property is excellent, but since the support force is weak by the foam layer, it is a configuration that can be easily broken by the shear force generated by the instantaneous stop of roller skates or bicycles, so it is a suitable balance of support and elasticity is a required configuration.
또한 대한민국등록특허공보 제821320호에는 "투수탄성 포장공법 및 투수탄성 포장구조체"가 게재되어 있으며, 기술의 구성내용은 다져진 쇄석기재층 위에 굵은 입자의 고무칩으로된 60mm두께의 하부탄성층, 작은 입자의 고무칩으로된 10mm두께의 상부 탄성층, 탑코팅층의 순서로 적층된 투수탄성 포장구조체로서 여기에서 상부 탄성층을 보호하기 위하여 탑코팅층을 형성하게 되면 투수성을 전혀 기대할 수 없으며, 또한 바인더의 사용비율이 기재되어 있지 않지만 많은량의 바인더를 사용할 경우에도 투수성을 기대할 수 없다.In addition, Republic of Korea Patent Publication No. 821320 discloses "permeable elastic pavement method and water permeable elastic pavement structure", and the composition of the technology consists of a 60mm-thick lower elastic layer made of coarse-grained rubber chips on a compacted crushed stone substrate layer, a small It is a water-permeable elastic pavement structure laminated in the order of a 10 mm thick upper elastic layer made of particle rubber chips and a top coating layer. Although the ratio of use is not described, water permeability cannot be expected even when a large amount of binder is used.

<실험예><Experimental example>
1. 원적외선 방사1. Far-infrared radiation
표 1은 실시예에 대한 원적외선 방사율 및 방사에너지 시험 결과를 나타낸다. 원적외선은 가시광선보다 파장이 길어서 눈에 보이지 않고 열작용이 크며 침투력이 강하다.Table 1 shows the far-infrared emissivity and radiant energy test results for Examples. Far-infrared rays have a longer wavelength than visible rays, so they are invisible to the naked eye, have a large thermal action, and have strong penetrating power.
이러한 열작용은 각종 질병의 원인이 되는 세균을 없애는 데 도움이 되고 인체에는 모세 혈관을 확장시켜 혈액순환과 세포조직 생성에 도움을 준다.This heat action helps to eliminate bacteria that cause various diseases and expands capillaries in the human body to help blood circulation and cell tissue creation.

2. 항균성2. Antibacterial
표 2는 실시예에 대한 원적외선에 의한 항균성을 측정하여 비교예과 대비한 값이다. 그 결과 실시예은 대장균, 녹농균 및 황색포도상구균의 24시간 후 초기 농도보다 8~10% 소멸됨을 알 수 있다. 이에 반에 비교예는 100%이상 증가함을 확인할 수 있다.Table 2 shows the values compared with Comparative Examples by measuring the antibacterial properties by far-infrared rays for Examples. As a result, it can be seen that the Example is 8 to 10% more extinct than the initial concentration after 24 hours of E. coli, Pseudomonas aeruginosa and Staphylococcus aureus. On the contrary, it can be confirmed that the comparative example increases by 100% or more.
실시예와 비교예의 구성의 차이는 상부시트에 코르크 및 적황토 유무이다. 따라서 적황토의 광물입자가 적외선을 발생시킴을 알 수 있다.The difference between the configuration of the example and the comparative example is the presence or absence of cork and red ocher on the upper sheet. Therefore, it can be seen that the mineral particles of red ocher generate infrared rays.
