Abstract
Description
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 more particularly, to a sheet type elastic packaging material having an antibacterial effect due to the generation of far-infrared rays and a method for producing the same, because the upper layer contains cork powder coated with red ocher.
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.Generally, trails and bicycle roads are designed to improve the convenience and health of the residents. The walkways, bicycle roads, and the like are provided with boundary stones on both sides of the landscapes and trees, and the walkway exposes the natural soil, When constructing a bicycle road or artificially constructing it, it is mostly constructed by using a pavement block made of cement to be installed on the surface of the earth, or by placing it on the ground surface by using concrete or ascon.
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.Walkways and bicycle roads that are exposed to conventional natural soils are washed off by rainwater during rainy days, and the walkway is easily lost, causing frequent maintenance. The walkways and bicycle roads constructed with sidewalks, concrete, The durability and the ease of construction are advantageous, but there is a problem that the user falls into the flaw or a serious injury occurs to the body even in a light collision of the users.
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,In order to solve the above-described problems, a rubber chip having a predetermined size of a waste tire, a silica sand and an adhesive are mixed at a predetermined ratio to form a packaging material having a predetermined length and width, and then the asphalt or concrete is packaged And the packaging material is packed in a double manner to improve the safety of users. However,
상기와 같은 포장재의 설치는 이중포장으로 이루어져야 하므로, 많은 시공시간이 소요되고, 고무칩이 탄성을 제공하므로 분진 또는 냄새가 심하게 발생되며, 폐타이어로부터 유해물질이 발산되는 문제점이 있었다.Since the installation of such a packaging material must be made in a double package, it takes a lot of time to construct and the rubber chip provides elasticity, so that dust or odor is generated severely and toxic substances are emitted from the waste tire.
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.Also, in the case of recycled products such as waste tires and waste polyurethane, some products contain heavy metals, which not only cause environmental pollution, but also cause a breakage phenomenon of the packaging material after construction, resulting in poor appearance.
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 packaging material, the sidewalk block, and the concrete are not all natural-friendly, and thus they have various problems such that they can not meet the desire to familiarize with the nature common to people who visit the park.

The description of the technical content is as follows. As the permeable elastic packing material in the laminated layers laminated in the order of the hearth, the filter layer (sand), the crushed stone layer, the lower support layer and the upper support layer, the constitution of the lower support layer is 70 ~ 10 to 30 parts of waste tire rubber chips having a particle diameter of 4 to 8 mm, and 10 to 20 parts by weight of a urethane adhesive as a whole. Since the content of the fine aggregate or silica sand of the lower support layer is large, the elasticity can not be expected to be high and the tensile strength can not be expected. Therefore, the layer can be easily broken by impact or shear force of the surface layer.

상기 실시예에서 상부시트의 코르크 및 적황토 분말입자를 제외하고 열가소성 탄성수지인 SEBS 블록공중합체를 70 중량부, 파라핀계 배합유 15 중량부, 및 탄산칼슘인 미네랄 필러 15중량부 투입한 것 이외에는 실시예와 동일하다.Except that 70 parts by weight of the SEBS block copolymer as the thermoplastic elastic resin, 15 parts by weight of the paraffin blended oil and 15 parts by weight of the mineral filler as the calcium carbonate except for the cork and red ocher powder particles in the upper sheet were added Which is the same as the embodiment.
<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. 이러한 열작용은 각종 질병의 원인이 되는 세균을 없애는 데 도움이 되고 인체에는 모세혈관을 확장시켜 혈액순환과 세포조직 생성에 도움을 준다. Table 1 shows the far infrared ray emissivity and radiant energy test results for the examples. Far infrared rays are longer than wavelengths of visible light, so they are invisible to the naked eye, have high thermal effects and strong penetration. This heat helps to eliminate the germs that cause various diseases, and it helps the blood circulation and cell tissue formation by expanding the capillaries in the human body.

2. 항균성2. Antimicrobial activity
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 antimicrobial activity of far infrared rays measured in Examples and compared with Comparative Example. As a result, it can be seen that the example decays 8 ~ 10% after 24 hours from the initial concentration of Escherichia coli, P. aeruginosa and Staphylococcus aureus. On the contrary, it can be confirmed that the comparative example increases by more than 100%.
실시예와 비교예의 구성의 차이는 상부시트에 코르크 및 적황토 유무이다. 따라서 적황토의 광물입자가 적외선을 발생시킴을 알 수 있다. The difference between the constitutions of the examples and the comparative examples is the presence of cork and red clay on the top sheet. Therefore, it can be seen that the mineral particles of red clay form infrared rays.
