국내에서는 테니스장, 육상트랙, 배구장, 농구장 등의 바닥을 현장시공형으로 작업할 때 풍우설한 시에는 작업에 막대한 애로가 있으며 또한 기후 조건이 양호할 때이더라도 현장 시공시 고무칩 탄성층 조성물 작업이 번잡하고 시공 바닥의 두께와 평탄성 유지에도 어려움이 있어 이를 공장 제품형 방식으로 개선하고자 하였는바 이와 관련된 종래 기술로서는 대한민국 공개특허 제1994-008841호(발명의 명칭 : 폐타이어를 이용한 경기장 탄성 바닥재의 제조방법, 출원일 : 1994.05.16.), 대한민국 공개특허 제1993-012231호(발명의 명칭 : 폐타이어를 이용한 토건용 고무블록의 제조방법, 출원일 : 1993.07.20.), 대한민국 공개특허 제1994-018182호(발명의 명칭 : 폐타이어를 이용한 탄성재 보도블록 및 그 제조방법, 출원일 : 1994.08.15.)에서 폐타이어 등의 가황고무를 분쇄한 고무칩에 바인더로서 폴리우레탄을 혼합하고 성형틀에서 70∼80°C로 10여초간 적정 압력을 가하여 성형 제조하거나, 특수 가교제를 혼합하고 프레싱 공법으로 160∼200°C로 7∼8분간 압형하여 판상재의 고무매트를 제조하는 기술이 있었다.In Korea, when working on the floor of tennis courts, track tracks, volleyball courts, basketball courts, etc., there are enormous difficulties in the work during heavy weather, and even when the weather conditions are good, the work of rubber chip elastic layer composition is complicated. In addition, there was a difficulty in maintaining the thickness and flatness of the construction floor, and this was to be improved to the factory product type. As a related art, Korean Patent Publication No. 194-008841 (Invention: Manufacturing method of stadium elastic floor using waste tire) , Filed Date: May 16, 1994), Republic of Korea Patent Publication No. 199-012231 (Invention name: Manufacturing method of civil rubber block using waste tire, Application Date: July 20, 1993), Republic of Korea Patent Publication No. 199-018182 Grinding vulcanized rubber such as waste tires in the name of the invention: elastic material press block using waste tires and a manufacturing method thereof, filing date: August 15, 1994 Polyurethane as a binder is mixed with rubber chips and molded at 70 to 80 ° C by applying an appropriate pressure for 10 seconds, or a special crosslinking agent is mixed and pressed at 160 to 200 ° C for 7 to 8 minutes by pressing. There has been a technique of manufacturing a rubber mat of plate material.
그런데 이들 종래 기술에서 사용된 성형틀은 비교적 작은 압착식 프레스로서 폭이 대체로 1.2M 이하이고 길이가 3M 이하인 특대형 프레스 이하의 성형 프레스이기 때문에 이러한 시설로는 폭이 120cm이고 두께가 3∼10mm이며 길이가 60∼20M인 탄성 바닥재가 생산할 수 없는 문제점이 있었다.However, the molds used in these prior arts are relatively small crimping presses, which are molding presses of oversized presses having a width of 1.2 M or less and a length of 3 M or less, and are 120 cm wide and 3 to 10 mm thick. There was a problem that the elastic flooring having a length of 60 to 20M can not be produced.
또한 상기 종래 기술들에 있어서는 고무 분말(칩)과 바인더를 혼합한 조성물을 성형틀에서 70∼80°C의 온도로 10초 전후 또는 열프레싱 공법으로 160∼200°C로 7∼8분간 압형하여 판상재를 제조하는 것으로 폭이 120cm이고 두께가 3∼10mm이며 길이가 60∼20M인 고무매트를 제조하기에는 무리가 있고 비경제적이며 품질 측면에서는 고무매트의 표면에 이형제가 부착되어 있어 표면의 접착이 크게 불량해지는 결점이 있었다.In addition, in the above-mentioned conventional techniques, the composition mixed with the rubber powder (chip) and the binder is pressed in a molding die at a temperature of 70 to 80 ° C. for 10 seconds or by a hot pressing method at 160 to 200 ° C. for 7 to 8 minutes. It is difficult to manufacture rubber mat of 120cm in width, 3 ~ 10mm in thickness and 60 ~ 20M in length by manufacturing plate material, and it is uneconomical and in terms of quality, release agent is attached to the surface of rubber mat. There was a defect that greatly deteriorated.
본 발명은 종래 기술이 갖는 문제점을 개선하기 위한 것으로, 이형제가 전혀 없어 접착제와의 접착에 이상이 없는 표면을 가지며 원주형으로 경화된 조성물의 지름이 커질수록 재단할 수 있는 길이가 길어지도록 되어 있는 탄성 롤 고무매트 의 제조방법을 제공하는데 그 목적이 있다.The present invention is to improve the problems of the prior art, there is no release agent at all has a surface with no abnormality in adhesion with the adhesive, and the larger the diameter of the circumferentially cured composition is longer to be cut It is an object of the present invention to provide a method for producing an elastic roll rubber mat.
상기와 같은 목적을 달성하기 위해 본 고안의 탄성 롤 고무매트의 제조방법은, 가황고무 또는 경화된 합성수지의 입자(1) 크기가 1∼5mm이며 절단면이 평면이고 모서리가 예리한 과립상의 다면체인 분말(칩)에 분말(칩)의 중량 대비 10-30%에 해당하는 폴리우레탄 수지를 바인더로서 혼합하여 고무 분말과 폴리우레탄 수지의 혼합 조성물을 형성하는 단계와; 상기 고무 분말과 폴리우레탄 수지의 혼합 조성물을 원통형 성형기에 투입하고 2.5∼10kg/cm2의 압력이 유지되는 상태에서 상온에서 경화(양생)시켜 경화된 원통형의 고무 분말과 폴리우레탄 수지의 혼합 조성물을 성형하는 단계와; 두께가 3∼10mm, 폭 120cm, 길이가 60∼20M가 되도록 경화된 원통형의 고무 분말과 폴리우레탄 수지의 혼합 조성물을 스카이빙(skiving)하는 단계로 구성된다.In order to achieve the above object, the manufacturing method of the elastic roll rubber mat of the present invention is a granular polyhedron powder having a particle size (1) of 1 to 5 mm and a flat cut surface and sharp edges of vulcanized rubber or cured synthetic resin ( Chip) to form a mixed composition of rubber powder and polyurethane resin by mixing a polyurethane resin corresponding to 10-30% by weight of the powder (chip) as a binder; The mixed composition of the rubber powder and the polyurethane resin is put into a cylindrical molding machine and cured (curing) at room temperature while maintaining a pressure of 2.5 to 10 kg / cm 2 to prepare a mixed composition of the cured cylindrical rubber powder and the polyurethane resin. Molding; And skiving a mixed composition of a cylindrical rubber powder and a polyurethane resin cured to have a thickness of 3 to 10 mm, a width of 120 cm, and a length of 60 to 20 M.

이어서 이와 같이 혼합된 고무 분말과 폴리우레탄 수지의 혼합 조성물을 원통형 성형기에 투입하고 다진 다음 압축판을 덮어서 2.5∼10kg/cm2의 압력이 유지되 는 상태에서 24시간 동안 양생시키며, 이 때 양생은 상온에서 실시하는 것을 원칙으로 하되 동절기에는 보온실에서 양생한다.Subsequently, the mixed composition of the rubber powder and the polyurethane resin thus mixed is put into a cylindrical molding machine, chopped, and then cured for 24 hours under the pressure of 2.5 to 10 kg / cm 2 by covering the compression plate. In principle, it should be carried out at room temperature, but in winter, it is cured in a warm room.
다음으로, 원통형 성형기에서 양생된 고무 분말과 폴리우레탄 수지의 혼합 조성물을 꺼내어 경화된 상기 혼합 조성물을 표면을 재단하는 표면 재단기인 피복 박리식 스카이빙기(도시하지 않음)에 걸어서 회전칼에 의해 일정한 두께로 껍질이 벗겨지도록 내부의 심에 회전칼이 접촉될 때까지 재단을 계속하여 도2의 본 발명의 탄성 롤 고무매트 평면도에 도시되어진 바와 같은 폭이 120cm이고 두께가 3∼10mm이며 길이가 60∼20M인 본 발명의 탄성 롤 고무매트를 제조할 수 있다.Next, a fixed thickness is taken by a rotary knife on a coated peeling skiving machine (not shown), which is a surface cutting machine which takes out the mixed composition of the rubber powder and the polyurethane resin cured from the cylindrical molding machine and cures the mixed composition. The cutting was continued until the rotary knife contacted the inner seam so that the shell was peeled off, and the width was 120 cm, the thickness was 3-10 mm, and the length was 60-60 as shown in the plan view of the elastic roll rubber mat of the present invention of FIG. The elastic roll rubber mat of the present invention, which is 20 M, can be produced.
이상에서 본 발명은 기재된 구체예에 대해서만 상세히 설명되었지만 본 발명의 기술 사상 범위 내에서 다양한 변형 및 수정이 가능함은 당업자에게 있어서 명백한 것이며, 이러한 변형 및 수정이 첨부된 특허청구범위에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the spirit of the present invention, and such modifications and modifications belong to the appended claims.
본 발명의 탄성 롤 고무매트는 두께가 3∼10mm, 폭 120cm, 길이가 60∼20M가 되도록 스카이빙하여 제조할 수 있으므로, 전동차 및 기관차의 객실의 하지제로 사용되는 시방에서 길이 방향으로 이음새가 없도록 시방이 되어 있는 경우와, 정구장, 배구장, 농구장 등의 구기장에서 길이 방향으로 이음새는 가급적 적도록 시방되어 있는 경우, 및 조오깅 코오스와 같이 가급적 길게 그리고 가급적 이음새는 없도록 하고 있는 시방에서도 사용될 수 있고, 또한 바닥 시공의 준비 공정 및 작업 공정에서 현장 시공형에 비하여 반제품인 공장 생산형이어서 현지 시공의 기간이 단축되고 작업도 크게 단순해지는 효과가 있다.The elastic roll rubber mat of the present invention can be manufactured by skiving to have a thickness of 3 to 10 mm, a width of 120 cm, and a length of 60 to 20 M, so that there is no seam in the longitudinal direction in the specification used as a base material of the passenger compartment of electric cars and locomotives. It can be used in the case where the specification is made, and in the case where the length of the seam is as small as possible in the ballparks such as tennis courts, volleyball courts, basketball courts, etc. In addition, it is a factory production type that is semi-finished product compared to the site construction type in the preparation process and work process of floor construction, so that the duration of local construction is shortened and work is greatly simplified.
