Abstract

본 발명은 원료고무로 천연고무, 폴리이소프렌 고무, 폴리부타디엔 고무, 스티렌-부타디엔 고무를 사용하고, 보강제로 카본 블랙 50 내지 90phr, 캐슈 변성된 페놀 수지 및/또는 캐슈 오일 5 내지 20phr과, 가류제로 헥사메틸렌테트라아민 도는 헥사메톡시메틸멜라닌 1 내지 10phr을 통상의 타이어 비드 필러용 고무 배합제와 함께 사용하는 것을 특징으로 하는 타이어 비드 필러용 고무 조성물에 관한 것이다. 본 발명에 다르며, 가류전 미가류 타이어 비드 필러용 고무 조성물의 강성을 낮추어 가공성이 우수하고, 비드 필러용 고무 조성물의 가류 후에는 모듈러스, 인장강도 및 경도를 크게 향상시킬수 있다. 또한 본 발명에 따른 고무 조성물을 타이어의 비드필러에 사용할 경우 높은 경도로 인하여 조종안정성이 양호하고, 카본 블랙의 과다한 사용을 피하여 발열에 의해 발생하는 문제를 감소시킬수 있다.The present invention uses natural rubber, polyisoprene rubber, polybutadiene rubber, styrene-butadiene rubber as raw material rubber, carbon black 50 to 90 phr as a reinforcing agent, cashew modified phenol resin and / or cashew oil 5 to 20 phr, and as a vulcanizing agent Hexamethylenetetraamine degree relates to a rubber composition for tire bead fillers, characterized in that 1 to 10 phr of hexamethoxymethylmelanine is used in combination with a rubber compound for conventional tire bead fillers. According to the present invention, the stiffness of the rubber composition for unvulcanized tire bead filler before vulcanization is lowered, so that the workability is excellent, and the modulus, tensile strength and hardness can be greatly improved after vulcanization of the rubber composition for bead filler. In addition, when the rubber composition according to the present invention is used for the bead filler of the tire, the steering stability is good due to the high hardness, and the problem caused by the heat generation can be reduced by avoiding excessive use of the carbon black.
