Description

스노우 타이어용 고무조성물{Rubber compound for snow tire}Rubber compound for snow tires {Rubber compound for snow tire}

본 발명은 스노우 타이어용 고무조성물에 관한 것으로서 보다 상세하게는 스노우 타이어용 고무조성물에 있어서, 코-폴리-파라페닐렌/3,4'-옥시다이페닐렌 테레프탈아미드[co-poly-(paraphenylene/3,4'-oxydiphenlylene terephthalamide)]의 아라미드 단섬유와 황(sulfur)이 배합된 마스터배치를 포함하여 스노우 특성, 마모성능이 향상된 스노우 타이어용 고무조성물에 관한 것이다.The present invention relates to a rubber composition for snow tires, and more particularly, to a rubber composition for snow tires, co-poly-paraphenylene / 3,4'-oxydiphenylene terephthalamide [co-poly- (paraphenylene / 3,4'-oxydiphenlylene terephthalamide)] relates to a rubber composition for snow tires with improved snow characteristics and wear performance, including a masterbatch containing aramid short fibers and sulfur.

기존에는 타이어의 스틸 코드나 섬유 코드를 보강시키기 위해서 사용되는 고무 조성물에 단섬유를 적용하여 왔다. 또한, 상기의 보강성 향상 이외에도 스노우 특성이 요구되는 고무 조성물에 스노우 특성을 향상시키기 위해 단섬유를 적용시키고 있다.Previously, short fibers have been applied to rubber compositions used to reinforce steel cords or fiber cords of tires. In addition, in addition to the above reinforcing properties, short fibers are applied to rubber compositions that require snow properties to improve snow properties.

스노우 타이어에 있어서, 스노우 타이어의 트레드 고무에 단섬유를 적용시, 고무조성물의 견인력 등은 크게 향상하나, 조성물의 주요 성분을 차지하는 폴리머와 단섬유의 상용성이 크게 하락하므로 인해 고무조성물의 마모특성이 하락하고 히스테리시스(hysteresis) 에너지 손실이 많으며 단섬유가 고무조성물로부터 이탈되 어 요구되는 특성이 급격히 하락하는 문제가 있다.In the snow tire, when the short fiber is applied to the tread rubber of the snow tire, the traction of the rubber composition is greatly improved, but the wear characteristics of the rubber composition are greatly reduced because the compatibility between the polymer and the short fiber, which constitutes the main component of the composition, is greatly reduced. There is a problem that this fall, there is a lot of hysteresis energy loss, and short fibers are separated from the rubber composition, the required properties are sharply dropped.

본 발명은 코-폴리-파라페닐렌/3,4'-옥시다이페닐렌 테레프탈아미드의 아라미드 단섬유와 황이 배합된 마스터배치를 사용함으로써, 상기 마스터배치 중의 아라미드 단섬유는 종래의 폴리-파라페닐렌 테레프탈아미드[Poly-(paraphenylene terephthalamide)]의 아라미드 단섬유에 비해 반응성 그룹이 증가하고, 또한 황으로 말단처리하여 반응성을 키우므로 인해 고무와의 친화력을 높여 상기의 마스터배치를 포함하는 고무조성물로 이루어진 고무를 포함하는 타이어는 오랜 시간 동안 주행하여도 상기 고무내에서 코-폴리-파라페닐렌/3,4'-옥시다이페닐렌 테레프탈아미드의 아라미드 단섬유의 이탈성이 감소하여 마모성능이 항상되고, 시스테리시스 손실을 작게하여 스노우 특성을 향상시킬 수 있다.The present invention uses a masterbatch in which aramid short fibers and sulfur of co-poly-paraphenylene / 3,4'-oxydiphenylene terephthalamide are combined, whereby the short aramid fibers in the masterbatch are conventional poly-paraphenyls. Compared to the short aramid fibers of poly- (paraphenylene terephthalamide), the reactive group is increased, and the sulfur is terminated with sulfur to increase the reactivity, thereby increasing the affinity with the rubber. Tires, including rubbers made of rubber, have reduced wearability of the aramid short fibers of co-poly-paraphenylene / 3,4'-oxydiphenylene terephthalamide in the rubber even after long running. As a result, the snow characteristics can be improved by reducing the loss of hysteresis.

본 발명은 상기에서 언급한 문제를 해결하기 위해 기존의 하기 식(1)의 폴리-파라페닐렌 테레프탈아미드[Poly-(paraphenylene terephthalamide)]의 아라미드 단섬유 대신 하기 식(2)의 코-폴리-파라페닐렌/3,4'-옥시다이페닐렌 테레프탈아미드[co-poly-(paraphenylene/3,4'-oxydiphenlylene terephthalamide)]의 아라미드 단섬유와 황(sulfur)이 배합된 마스터배치를 스노우 타이어용 고무조성물에 포함하도록 하여 스노우 특성, 마모성능이 향상된 스노우 타이어용 고무조성물의 제공을 목적으로 한다.In order to solve the above-mentioned problems, the present invention replaces the aramid short fibers of the poly- (paraphenylene terephthalamide) of the following formula (1) with the co-poly- of the formula (2). Masterbatch blended with aramid short fibers and sulfur of paraphenylene / 3,4'-oxydiphenylene terephthalamide It is intended to provide a rubber composition for snow tires with improved snow properties and wear performance by being included in the rubber composition.
