The present invention relates to a tire comprising a sealant layer and a sound-absorbing material layer. The tire comprises: a sound-absorbing material layer located inside the tire; and a sealant layer located between the inner surface of the tire and the sound-absorbing material layer, and applied on the inner surface of the tire. The sound-absorbing material layer comprises: a first porous material having closed cells; and a second porous material having open cells. Therefore the tire: can self-seal by means of the sealant layer applied on the inner surface of the tire, when the tire is punctured; comprises a sound-absorbing material and thus has a sound reducing performance; and can prevent fine fragments of the sound-absorbing material from degrading the function of a sealant and can also maintain the sound-reducing performance, even when a nail penetrates the tire and the sealant and reaches the sound-absorbing material.

    La présente invention concerne un pneu comprenant une couche d'étanchéité et une couche de matériau absorbant le son. Le pneu comprend : une couche de matériau absorbant le son située à l'intérieur du pneu ; et une couche d'étanchéité située entre la surface interne du pneu et la couche de matériau absorbant le son, et appliquée sur la surface interne du pneu. La couche de matériau absorbant le son comprend : un premier matériau poreux présentant des cellules fermées ; et un second matériau poreux présentant des cellules ouvertes. Par conséquent, le pneu peut s'auto-sceller au moyen de la couche d'étanchéité appliquée sur la surface interne du pneu, lorsque le pneu est perforé ; comprend un matériau absorbant le son et présente ainsi une performance de réduction du son ; et peut empêcher de fins fragments du matériau absorbant de son de dégrader la fonction d'un agent d'étanchéité et peut également maintenir la performance de réduction du son, même lorsqu'un clou pénètre le pneu et l'agent d'étanchéité et atteint le matériau absorbant le son.

    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.
