The present invention relates to a tire including a sealant layer and a sound absorption material layer. The tire includes: the sound absorption material layer positioned on the inner side of the tire; and the sealant layer positioned between the inner surface of the tire and the sound absorption material layer and applied on the inner surface of the tire. The sound absorption material layer includes: a first porous material having a closed cell; and a second porous material having an open cell. The tire including the sealant layer and the sound absorption material layer can be stitched by itself by the sealant layer applied to the inner surface of the tire when a puncture is generated. The tire including the sealant layer and the sound absorption material layer has a noise reduction performance by including a sound absorption material. The tire including the sealant layer and the sound absorption material layer also can prevent a function of a sealant from being deteriorated due to a micro piece of the sound absorption material when a nail reaches the sound absorption material by passing through the tire and the sealant. Moreover, the tire including the sealant layer and the sound absorption material layer can maintain noise reduction performance.
본 발명은 실란트층 및 흡음재층을 포함하는 타이어에 관한 것으로서, 타이어는 타이어 내측에 위치하는 흡음재층, 그리고 상기 타이어 내측면과 상기 흡음재층 사이에 위치하며, 상기 타이어 내측면에 도포된 실란트층을 포함하며, 상기 흡음재층은 독립 기공(closed cell)을 가지는 제 1 다공성 재료, 및 연속 기공(open cell)을 가지는 제 2 다공성 재료를 포함함으로써, 타이어 내측면에 도포된 실란트층에 의하여 펑크 발생시 자가 봉합을 할 수 있으면서도, 흡음재를 포함하여 소음 저감 성능을 가지며, 못이 타이어와 실란트를 관통하여 흡음재에 도달시에도 흡음재의 미세 조각이 실란트의 기능을 저하시키는 것을 방지하고 소음 저감 성능도 유지할 수 있다.
