Description
본 발명은 타이어의 스노우 특성을 향상시키기 위하여 타이어 트래드에 단섬유를 함유시킨 것에 관한 것으로 특히 표면처리된 아라미드 단섬유를 함유한 스노우 타이어용 트래드 고무에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the inclusion of short fibers in tire treads to improve the snow properties of tires, and more particularly to tread rubber for snow tires containing surface treated aramid short fibers.
일반적으로 빙(氷)판인 노면을 운행하는 차량용 타이어 트레드에는 지면과의 마찰력 향상을 위하여 체인을 감거나 트레드 표면에 강철 징, 못 등을 박아서 운행하는 것이 일반적이었으나, 진동이 많이 생기고 설치와 제거가 수고로운 단점이 있다.In general, tire treads for vehicles that run on ice roads were usually rolled up with chains or steel gages or nails on the tread surface to improve friction with the ground. There is a laborious disadvantage.
이상의 단점을 개선하고자 타이어 트레드 자체가 강한 마찰력을 갖도록 암석분, 모래, 철분, 섬유 등을 배합하여 타이어 트레드를 제조하고 있으나, 이들 배합성분의 합리적인 배합비율에 의한 물성향상보다는 고무자체의 열화를 초래하여 타이어의 수명단축만을 초래하는 단점이 있었다.In order to improve the above disadvantages, the tire tread is manufactured by mixing rock powder, sand, iron powder, and the like so that the tire tread itself has strong frictional force, but it causes deterioration of the rubber itself rather than improvement of physical properties due to rational mixing ratio of these ingredients. Therefore, there was a disadvantage of only reducing the life of the tire.
한국특허 79-1559호 공보에 기재된 바에 의하면 부타디엔 고무에 실리카 충 진제, 가소제, 유황기어제, 촉진제로 구성되는 고무조성물을 이용하므로서 설상면등에서 우수한 마찰특성을 나타낸다고 공개하고 있으나 다소간의 가황촉진효과로 고무가 잘 경화되어 강도에 따른 마찰개수가 증대되는 효과가 있는 반면에 마모가 심하고 폭설이 심한 경우에는 필요한 수준의 미끄럼 방지 효과는 얻을 수 없었다According to Korean Patent No. 79-1559, the rubber composition composed of silica filler, plasticizer, sulfur gear agent, and accelerator is used for butadiene rubber. While the rubber is hardened well to increase the number of frictions according to the strength, in the case of heavy wear and heavy snow, the required level of anti-slip effect was not obtained.
이같은 문제점을 해결하기 위하여 타이어 트래드에 단섬유를 적용하여 타이어의 스노우 특성을 향상시켰는데, 단섬유를 트래드에 적용시, 트래드의 견인력 등은 크게 향상하나, 트래드 조성물의 주요 성분을 차지하는 폴리머와 결합력이 낮아단섬유가 트래드로 부터 분리되는 문제가 있다.In order to solve this problem, the tire tread is applied to the tire tread to improve the snow characteristics of the tire. When the short fiber is applied to the tread, the traction of the tread is greatly improved, but the polymer and the bonding force occupy the main components of the tread composition. This low short fiber has a problem that is separated from the tread.
이상과 같은 타이어 트래드 고무에 고무 친화성 재료로 코팅된 아라미드 단섬유를 스노우용 타이어의 트래드 고무에 적용시켜 고무 내의 폴리머와 결합성을 향상시키는 것에 특징이 있다.The aramid short fibers coated with the rubber affinity material to the tire tread rubber as described above is characterized in that it is applied to the tread rubber of the tire for snow to improve the bond with the polymer in the rubber.
본 발명에 따른 아라미드 단섬유를 함유하는 스노우 타이어용 트래드 고무는 스노우 타이어의 트래드 고무를 구성함에 있어서, 폴리머, 카본블랙과 실리카와 같은 보강제, 가황제, 가류 촉진제와 함께 단섬유를 포함하여 구성하되 상기 단섬유는 직경 1mm이하, 길이 10mm이하인 아라미드 단섬유이고, 상기 아라미드 단섬유의 표면에는 고무친화성물질로 코팅하여 트래드 고무조성물 내에서 아라미드 단섬유가 분리되어 이탈되는 것을 방지한다.The tread rubber for snow tires containing aramid short fibers according to the present invention comprises a short fiber together with a polymer, reinforcing agents such as carbon black and silica, a vulcanizing agent and a vulcanization accelerator, in the tread rubber of the snow tire. The short fibers are aramid short fibers having a diameter of 1 mm or less and a length of 10 mm or less, and coated with a rubber-compatible material on the surface of the short aramid fibers to prevent separation of the aramid short fibers in the tread rubber composition.
상기 본 발명에 따른 아라미드 단섬유를 함유한 스노우 타이어용 트래드 고무는 아라미드 단섬유가 타이어의 트래드 내에서 랜덤하게 존재하되 그 일부는 세워져 그 단부가 트래드 표면에 노출된다. 단부가 노출된 아라미드는 트래드 표면에서 노면과의 마찰력을 증대한다. In the tread rubber for snow tires containing the short aramid fibers according to the present invention, the short aramid fibers are present randomly in the tread of the tire, and a part thereof is erected so that the ends thereof are exposed to the tread surface. The aramid with exposed ends increases friction with the road surface at the tread surface.
그리고 본 발명에 따른 아라미드 단섬유를 함유한 스노우 타이어용 트래드 고무는 상술한 바와 같은 표면처리가 된 아라미드 단섬유를 1phr~5phr 정도 첨가시킨 것을 특징으로 하며, 아라미드 단섬유의 화학식은 3,4-Diaminodiphenylether-para-phenylenediamine-terephthalyl chloride copolymer이며, TEIJIN LIMITED 회사에 의해 제조되었으며, 사용명은 TECHNORA T323SB이다.And the tread rubber for snow tires containing aramid short fibers according to the present invention is characterized in that about 1phr to about 5phr of the aramid short fibers subjected to the surface treatment as described above, the chemical formula of aramid short fibers is 3,4- Diaminodiphenylether-para-phenylenediamine-terephthalyl chloride copolymer. Manufactured by TEIJIN LIMITED. The name is TECHNORA T323SB.
상술한 바와 같이 본 발명에 따른 아라미드 단섬유를 함유한 스노우 타이어용 트래드 고무는 아라미드 단섬유가 매트릭스인 폴리머와 결합이 안정되므로 단섬유가 분리되지 않아 트래드가 빙판노면에서 마찰력을 충분히 발휘시켜 스노우 특성을 유지한다.As described above, the tread rubber for snow tires containing the short aramid fibers according to the present invention is stable because the aramid short fibers are bonded to the matrix polymer, so that the short fibers are not separated, so that the tread exhibits sufficient friction on the ice surface. Keep it.
