본 발명은 자동차의 실내 바닥에 깔리는 바닥매트에 관한 것으로, 보다 상세하게는 EVA(Ethylene Vinyl Acetate) 발포 수지를 이용하여 바닥매트를 제작함으로써, 제조원가의 절감은 물론 재사용이 가능하므로 경제성을 향상시킴과 아울러 환경 오염을 방지하여 환경친화적인 EVA 발포 수지를 이용한 자동차용 바닥매트 제조방법에 관한 것이다.
The present invention relates to a floor mat laid on an indoor floor of an automobile. More specifically, by manufacturing a floor mat using an EVA (Ethylene Vinyl Acetate) foam resin, it is possible to reduce manufacturing costs and reuse, thereby improving economics. In addition, the present invention relates to a method for manufacturing a floor mat for an automobile using environmentally friendly EVA foam resin by preventing environmental pollution.

일반적으로 자동차용 바닥매트는, 자동차의 실내 바닥에 설치되어 운전자와 탑승자가 발을 내딛는 위치의 바닥 오염방지와 실내 청결을 유지함과 아울러 미끄럼을 방지하면서 미관을 미려하게 하는 부가적인 기능도 포함하고 있다.In general, a car floor mat is installed on the interior floor of a car to prevent floor contamination and interior cleanliness of the driver's and passengers' foot positions, as well as to add slipperiness and beauty. .

상기 자동차용 바닥매트는, 고무와 폴리염화비닐(PVC) 소재가 널리 사용되어 왔으며, 상기 고무 소재의 매트는, 고무 특유의 강한 냄새가 실내 또는 차량 내부에 오래도록 남아 있어서 거부감을 줄 뿐만 아니라 제조원가가 매우 비싼 문제점이 있었고, 상기 폴리염화비닐(PVC) 소재의 매트는, 인체에 유해한 염소 성분을 함유하고 있을 뿐만 아니라 소각시 다이옥신 배출 등의 환경 오염을 유발하는 문제점이 있으며, 특히 재생 PVC에는 규정치 이상의 중금속이 함유되어 있어서 사용자에 대해 중금속 노출의 위험을 내포하고 있는 실정이다.In the automotive floor mat, rubber and polyvinyl chloride (PVC) materials have been widely used, and the mat of the rubber material has a strong smell peculiar to the rubber and remains in the room or inside the vehicle for a long time, thereby providing a sense of rejection and cost. There was a very expensive problem, the polyvinyl chloride (PVC) material mat, not only contains a chlorine component harmful to the human body, but also causes problems such as environmental pollution, such as dioxin emissions during incineration, especially in recycled PVC Since heavy metals are contained, there is a risk of heavy metal exposure to users.

또한, 최근에는 고무판과 상기 고무판에 나일론사가 접착제로 부착된 바닥매트를 사용하고 있으나, 바닥매트의 둘레부분의 박리 현상을 방지하기 위해 별도로 재봉처리하므로 제조공정이 길어 생산성이 저하되면서 제조원가가 상승하는 문제점이 있었고, 무게가 무거우면서도 먼지가 흡착되므로 취급 및 청소가 용이하지 못한 문제점이 있었다.
In addition, in recent years, a rubber sheet and a floor mat having nylon yarn attached to the rubber plate are used as adhesives, but are separately sewn to prevent peeling of the circumferential portion of the floor mat. There was a problem, the weight is heavy, but because the dust is adsorbed there was a problem that handling and cleaning is not easy.

이에 상술한 바와 같은 종래의 제반 결함을 감안하여 이루어진 것으로, 본 발명의 목적은, EVA(Ethylene Vinyl Acetate) 발포 수지를 이용하므로 무게가 가벼워 취급이 용이함과 아울러 먼지가 흡착되지 않고 세척이 용이하여 위생적으로 사용할 수 있는 EVA 발포 수지를 이용한 자동차용 바닥매트 제조방법을 제공함에 있다.In view of the above-described conventional defects, the object of the present invention is to use an EVA (Ethylene Vinyl Acetate) foamed resin, which is light in weight, easy to handle, and does not adsorb dust, so it is easy to clean and hygienic. The present invention provides a method for manufacturing a car floor mat using the EVA foam resin can be used as.

또한, 본 발명의 다른 목적은, EVA(Ethylene Vinyl Acetate) 발포 수지를 이용하므로 바닥매트의 제조원가를 절감함과 아울러 재생이 가능하여 경제적이면서 환경 오염을 방지하는 친환경적인 EVA 발포 수지를 이용한 자동차용 바닥매트 제조방법을 제공함에 있다.
In addition, another object of the present invention is to use an EVA (Ethylene Vinyl Acetate) foam resin, thereby reducing the manufacturing cost of the floor mat and recyclable, economical and environmentally friendly flooring using an EVA foam resin to prevent environmental pollution The present invention provides a method for manufacturing a mat.
