본 발명은 실란트층 및 흡음재층을 포함하는 타이어에 관한 것으로서, 상기 타이어는 타이어 내측면에 부착된 흡음재층, 그리고 상기 타이어 내측면과 상기 흡음재층 사이에 배치되며, 상기 흡음재층을 상기 타이어 내측면에 부착시키는 실란트(sealant)를 포함하는 실란트층을 포함한다. 상기 타이어는 타이어 내측면에 도포된 실란트층 위에 흡음재층을 부착하여 펑크 발생시 자가 봉합을 할 수 있으면서도 소음 저감 성능을 가지며, 흡음재의 평균 기공 크기를 증가시킴으로써, 실란트와 흡음재 사이의 비표면적을 줄여 실란트의 흐름성을 향상시키고, 못이 타이어와 실란트를 관통하여 흡음재에 도달시에도 못의 표면과 흡음재의 부착 비표면적을 감소시켜 흡음재의 미세 조각이 실란트의 기능을 저하시키는 것을 방지하고 소음 저감 성능도 유지할 수 있다.

    The present disclosure relates to a tire (1) including a sealant layer (2) and a sound-absorbing material layer (3); the sealant layer (2) is disposed between the inner surface of the tire and the sound-absorbing material layer (3) and includes a sealant for adhering the sound-absorbing material layer to the inner surface of the tire (1). The sound-absorbing material layer (3) includes a first porous material having an average pore size of 1200 to 2400 µm.The tire has noise reduction performance while enabling a self-sealing operation to be carried out when a tire puncture occurs by adhering a sound-absorbing material layer to a sealant layer applied to an inner surface of the tire, improves flowability of the sealant by increasing average pore size of a sound-absorbing material, thereby reducing specific surface area between the sealant and the sound-absorbing material, and prevents fine pieces of the sound-absorbing material from deteriorating function of the sealant and can also maintain noise reduction performance by decreasing adhesion specific surface area between the surface of the nail and the sound-absorbing material even when a nail reaches the sound-absorbing material by penetrating the tire and the sealant.
