Description
본 발명은 고무기재에 마찰계수가 높은 무기물 입자를 혼합시킴으로써 내마모성 뿐만 아니라 마른바닥, 눈길, 빗길 및 젖은 바닥 등에서의 내슬립성을 향상시킬 수 있도록 하는 고무 조성물, 이를 이용하여 제조되는 신발창 및 고무용품에 관한 것이다.The present invention provides a rubber composition capable of improving not only abrasion resistance but also slip resistance on dry, snowy, rain and wet floors by mixing inorganic particles with a high coefficient of friction with a rubber base, and shoe soles and rubber articles manufactured using the same is about
최근 생활수준의 급격한 향상으로 사람들이 생활하는 모든 공간, 즉 빌딩, 지하도 등과 같은 각종 건축물의 복도나 계단 등이 대리석 또는 각종 타일을 사용하여 시공됨에 따라 일반적인 일상생활 중에 빈번하게 미끄러져 골절상 등을 입는 사고가 빈번하게 발생하고 있으며, 또한 얼음이 얼어붙은 빙판 또는 얼음이 녹아 수막이 형성된 바닥면, 빗길 등에서도 사람들이 미끄러져 골절되는 부상의 안전사고들이 빈번하게 발생하고 있다.With the recent rapid improvement in living standards, all spaces where people live, that is, corridors and stairs of various buildings such as buildings and underpasses, are constructed using marble or various tiles, so it is common to slip and suffer fractures frequently in daily life. Accidents occur frequently, and safety accidents in which people slip and fracture are frequently occurring even on a frozen ice sheet or a floor surface where a water film is formed by melting ice, or on a rainy road.
따라서 미끄럼을 방지하기 위한 수단들이 다양하게 개발되고 있으며, 관련 선행기술로써 특허문헌 1에서는 밑창에 횡방향으로 형성된 하나 이상의 안내 홈을 가지고, 이 안내 홈에는 미끄럼 방지부재가 끼워져 사용되며, 미사용시에는 미끄럼 방지부재를 굽에 형성된 하나 이상의 보관구멍에 보관할 수 있도록 한 구조를 갖는 미끄럼 방지부재가 구비된 신발이 개시되어 있지만, 상기와 같은 구조를 갖는 신발의 경우에는 동절기 눈길이나 빙판 등이 있는 야외에서 보행 후 건물의 실내로 진 입시 반드시 미끄럼 방지부재를 제거해야 하는 불편함이 있었다.Therefore, various means for preventing slipping have been developed, and as a related prior art, Patent Document 1 has one or more guide grooves formed in the transverse direction on the sole, and an anti-slip member is inserted into this guide groove, and when not in use, There is disclosed a shoe provided with an anti-slip member having a structure that allows the anti-slip member to be stored in one or more storage holes formed in the heel, but in the case of a shoe having the structure as described above, in the case of a shoe having the above structure, it is used outdoors in winter with snow or ice. When entering the building after walking, it was inconvenient to have to remove the non-slip member.
즉, 상기와 같은 신발창은 눈길이나 빙판 등이 있는 바닥면에는 미끄럼 방지기능이 일부 구현될 수 있으나, 그 외 지역에서는 미끄럼 방지부재가 오히려 보행을 방해하는 요소로 작용하는 문제점이 있다.That is, the shoe sole as described above may have a non-slip function partially implemented on the floor surface with snow or ice, but there is a problem in that the non-slip member acts as an element that prevents walking in other areas.
또한, 특허문헌 2에서는 신발창의 저면에 홈을 형성하여, 홈과 그 홈 상부 주위를 덮는 논슬립 혼합물을 형성한 것을 특징으로 하는 미끄럼 방지 신발창을 제안하였으나, 이는 제조 공정이 복잡할 뿐만 아니라, 실제 마른바닥, 눈길, 빗길 및 젖은 바닥 등에서의 내슬립성을 만족시키지 못하는 문제점이 있었다.In addition, Patent Document 2 proposes a non-slip sole characterized in that a groove is formed on the bottom surface of the sole to form a non-slip mixture covering the groove and the upper periphery of the groove. There was a problem in that it did not satisfy the slip resistance on the floor, snow, rain, and wet floors.
따라서 신발창에 내슬립 특성을 부여하기 위해서 일반적으로 유리전이 온도가 높은 부틸고무가 사용되고 있지만 가공성이 떨어지고 내마모성이 취약하다는 단점이 있다. Therefore, butyl rubber having a high glass transition temperature is generally used to impart slip resistance to the sole, but it has disadvantages in that it has poor processability and poor abrasion resistance.
이를 해결하기 위하여 특허문헌 3에서는 합성고무, 카본블랙, 촉진제, 가황제 및 프로세스 오일 등의 물질을 혼합한 후 사출 성형과정을 거쳐 제조되는 내마모성 높인 겉창용 고무 조성물이 개시되어 있으나, 이와 같이 카본블랙을 고무 조성물로 포함하여 신발용 고무를 제조하여 사용하는 경우에는 내마모성 등과 같은 물리적 성질은 비교적 우수하게 나타나지만 상기와 같은 카본블랙이 많이 첨가됨에 따라 제품의 경도가 높아지게 되어 내슬립 특성이 저하되는 문제점이 있다.In order to solve this problem, Patent Document 3 discloses a rubber composition for an outsole with improved abrasion resistance that is manufactured through an injection molding process after mixing materials such as synthetic rubber, carbon black, accelerator, vulcanizing agent and process oil. In the case of using as a rubber composition to manufacture and use rubber for footwear, physical properties such as abrasion resistance are relatively excellent, but as a lot of carbon black as described above is added, the hardness of the product increases and slip resistance is lowered. have.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 고무기재에 마찰계수가 높은 무기물 입자를 혼합시킴으로써 내마모성 뿐만 아니라 마른바닥, 눈길, 빗길 및 젖은 바닥 등에서의 내슬립성을 향상시킬 수 있도록 함을 과제로 한다.Therefore, the present invention is to solve the above problems, and by mixing inorganic particles with a high coefficient of friction with a rubber base material, it is possible to improve not only abrasion resistance but also slip resistance on dry floors, snowy roads, rain and wet floors, etc. make it a task

In addition, the particle size is applied by grinding into fine particles of 0.001 ~ 1.0mm. Here, when the sintering condition or the particle size is out of the above range, there is a fear that the efficiency of improving the abrasion resistance and slip resistance may be reduced.
