Description

완충용 바닥재{A shock absorbing floor}A shock absorbing floor

본 발명은 냄새가 나지 않고 수축되지 않음으로서 실내용으로 사용가능한 완충용 바닥재에 관한 것이다.The present invention relates to a cushioning flooring which can be used indoors by not smelling or shrinking.

완충용 바닥재를 실내에 설치시는 접착제와 유기화합물을 사용함으로서 인체에 유해한 가스와 냄새가 많이 발생하며 시간이 경과함에 따라 수축되는 등의 문제점이 있으므로 이를 해결하고자 냄새를 제거하여 인체에 무해하고 수축되지 않는 완충용 바닥재를 개발한 것이다.When installing the buffer flooring material indoors, adhesives and organic compounds are used to generate harmful gases and odors that are harmful to the human body and shrink over time. Developed a cushioning flooring material.

본 발명은 완충용 바닥재에 관한 것으로, 보다 상세하게는 냄새가 나지 않고 큐션성이 양호하여 실내용으로 사용가능한 완충용 바닥재에 관한 것이다.The present invention relates to a cushioning flooring, and more particularly, to a cushioning flooring material which can be used for indoor use because of good smell and good curability.

현재 보도블럭, 조깅로 및 운동장 트랙과 건축물옥상의 휴식공간 등의 실외에는 합성수지로 된 완충용 바닥재가 많이 사용되고 있으나 상기의 바닥재를 실내에서 사용할 경우에는 접착제와 유기화합물을 많이 사용함으로서 시공 후에도 오랜 시간동안 휘발성물질에 의한 냄새뿐만 아니라 인체에 유해한 가스 등이 발생하고 아울 러 시간이 경과함에 따라 상기 바닥재에서 수축과 갈라짐 현상이 발생하며 특히 시공하는데 시간이 많이 소요되는 등의 단점이 있었다.  Currently, cushioning flooring made of synthetic resin is used a lot in the outdoor areas such as sidewalk blocks, jogging paths, playground tracks, and rest areas on building roofs. In addition to the odor caused by volatiles, as well as harmful gases to the human body and the occurrence of the shrinkage and cracking phenomenon occurs in the flooring as time elapsed, in particular, there was a disadvantage in that it takes a long time to install.

본 발명은 상기의 문제점을 해결하고자 안출한 것으로서, 이의 발명요지는 하부의 금형판(미도시) 내에 미세한 EPDM고무칩을 투입하여 비교적 넓은(90cm×180cm) EPDM고무판(2)을 형성하되 이 EPDM고무판(2)의 내측에는 통공부(3a)를 다수개 형성한 평판형의 보강재(3)를 매입하고 상기 EPDM고무판(2)의 상면에는 폴리우레탄칩과 EPDM고무칩을 1:1의 중량비로 혼합하여 압축 성형한 상판(4)을 얹은 다음 열가소성TPU(미도시)를 투입한 후 프레스로 압착한 후 상기 바닥재몸체(1)의 표면부에 자외선(U/V)잉크를 분사한 후 U/V조사기로 조사(照射)하여 U/V경화층(5)을 형성한 완충용 바닥재몸체(1)를 제작한 것이다. 이 완충용 바닥재몸체(1)를 실내에 설치할 경우에는 완충용 바닥재몸체(1)의 측면부를 서로 대접한 후 U/V(자외선)조사기로 상기 대접부분을 U/V조사하는 U/V 코팅방법으로 접착하는 것이다.The present invention has been made to solve the above problems, the present invention is to form a relatively wide (90cm × 180cm) EPDM rubber plate (2) by putting a fine EPDM rubber chip in the lower mold plate (not shown), but the EPDM Inside the rubber plate 2, a plate-shaped reinforcing material 3 having a plurality of through holes 3a is embedded therein, and on the upper surface of the EPDM rubber plate 2, a polyurethane chip and an EPDM rubber chip are placed at a weight ratio of 1: 1. Put the compression-molded upper plate (4), and then put a thermoplastic TPU (not shown), and then pressed by a press and then sprayed ultraviolet (U / V) ink to the surface of the flooring material (1) U / Irradiating with a V irradiator to manufacture a flooring body 1 for the buffer in which the U / V hardened layer (5) was formed. When the cushioning flooring body 1 is installed indoors, after the side parts of the cushioning flooring body 1 are welded to each other, a U / V coating method of U / V irradiation of the welding portion with a U / V (ultraviolet ray) irradiator It is to be bonded.

상기와 같이 본 발명의 완충용 바닥재는 EPDM고무칩에 보강재를 삽입함으로서 수축되지 않고 큐션성이 양호한 형상을 유지하며, 인체에 무해하고 냄새가 없으며 다양한 색상과 문양으로 형상이 미려하고, 또한 연결부위에는 접착제 대신에 U/V 코팅경화방식을 사용함으로서 오염이 적고 청소가 용이하며 또한 난연제를 사용하여 화재 발생시에도 안전하므로서 특히 어린이놀이방이나 유치원등에서 사용 시 완충효과로 사고를 예방하며 시공작업이 간편하여 시공작업시간과 인원을 절감 할 수 있으므로 매우 경제적이고 실용적인 효과가 있는 것이다.As described above, the cushioning flooring material of the present invention does not shrink by inserting a reinforcing material into the EPDM rubber chip and maintains a good shape of cushioning, and is harmless to the human body, has no smell, and is beautiful in shape with various colors and patterns, and also connects parts. The use of U / V coating hardening method instead of adhesive is less polluting and easy to clean, and it is safe even in case of fire by using flame retardant. Construction work time and personnel can be reduced, so it is very economical and practical effect.

도1은 본 발명의 사시도이고, 도2는 도1의 분리사시도이다.1 is a perspective view of the present invention, Figure 2 is an exploded perspective view of FIG.

이를 도면에 의거하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the drawings as follows.

본 발명은 상기의 문제점을 해결하고자 안출한 것으로서, 이를 실시할 때는 하부의 금형판(미도시) 내에 투입한 2~3mm되는 미세한 EPDM고무칩을 투입하여 EPDM고무판(2)을 형성한 후 이 EPDM고무판(2) 내부에는 다수개의 통공부(3a)를 일정간격으로 형성한 합판 또는 경질수지로 된 보강재(3)를 매입하고 상기 EPDM고무판(2)의 상면에는 미세한 크기의(2~3mm)폴리우레탄칩과 상기한 EPDM고무칩을 1:1의 중량비로 투입하여 압축 성형한 상판(4)을 얹은 다음 열가소성 재질의 TPU(미도시)를 소량 투입하여 이를 170~180℃에서 5~10분 동안 프레스로 압착한 다음 상기 바닥재몸체(1)의 표면부에 자외선(U/V)잉크를 0.5~1mm두께로 분사(spray)하여 도포하고 이어서 U/V조사기로 3~7초 동안 조사(照射)하여 U/V경화층(5)을 형성한 완충용 바닥재몸체(1)를 제작한다. 상기와 같이 구성된 본 발명은 실내바닥재로 이용할 때는 비교적 넓은(90cm×180cm) 완충용 바닥재몸체(1)를 어린이놀이방이나 유치원과 같은 실내놀이실 등에 설치할 경우에는 상기 바닥재몸체(1)의 가장자리인 측면부를 밀착되게 대접한 후 U/V코팅방법으로 접착하여 U/V경화층(5)을 형성하는 것인 바, 이는 설치방법이 간단하고 설치비용이 줄어들 뿐만 아니라 EPDM고무칩 사이에 보강재를 매입함으로서 큐션성이 양호하고 탄성력이 좋고 화공약품을 사용하지 않아 냄새가 없으며 인체에 무해하고 다양한 문양과 색상으로 형상이 미려한 특징이 있다.The present invention has been made to solve the above problems, when performing the EPDM rubber plate (2) to form a EPDM rubber plate (2) by inserting a fine EPDM rubber chip into the lower mold plate (not shown) to form this EPDM Inside the rubber plate 2, a reinforcing material 3 made of plywood or hard resin having a plurality of through holes 3a formed at predetermined intervals is embedded, and a fine size (2-3 mm) poly is formed on the upper surface of the EPDM rubber plate 2. Put the urethane chip and the above EPDM rubber chip in a weight ratio of 1: 1, put the compression-molded top plate 4, and then add a small amount of thermoplastic TPU (not shown), which is then applied at 170 to 180 ° C. for 5 to 10 minutes. After pressing by pressing, the UV (U / V) ink is sprayed onto the surface of the flooring material 1 with a thickness of 0.5 to 1 mm, and then irradiated with a U / V irradiator for 3 to 7 seconds. The buffer flooring body 1 in which the U / V hardened layer 5 was formed is produced. The present invention configured as described above is a side portion that is the edge of the flooring body (1) when installed in the indoor playroom, such as a children's playroom or kindergarten when a relatively wide (90cm × 180cm) cushioning flooring body (1) when used as an indoor flooring material To be closely adhered to and then bonded by U / V coating to form a U / V hardened layer (5), which is a simple installation method and reduces installation costs as well as by purchasing reinforcement between EPDM rubber chips. It has good cushioning properties, good elasticity, no chemicals, no smell, harmless to human body, and beautiful shape with various patterns and colors.
