Embodiment 1 to Embodiment 3

[0072] The components in the following Table 1 were mixed to prepare a sealant-forming composition, and then coated on one surface of a porous sound-absorbing material (polyurethane foam) with a thickness of 8mm, and then carried out a cross-linking reaction at a high temperature of 170°C to form A layer of sealant with a thickness of 4mm. A release paper having the same area as the sealant layer was laminated on the formed sealant layer.

[0073] After peeling off the release paper from the sound-absorbing member for noise reduction prepared as described above, as figure 1 As shown, a sound-absorbing member for noise reduction was pasted so that the sealant layer faced the inner inner surface of the inner liner of a 235 / 45R17 tire (manufactured by Hankook Tire Co., Ltd.) to prepare a tire.

Abstract

Pneumatic tire and a method for manufacturing the same, wherein the pneumatic tire includes a porous sound-absorbing material adhered via a sealant layer to the inside surface of an inner liner, wherein the sealant layer comprises 100 to 400 parts by weight of polyisobutylene, 10 to 100 parts by weight of an inorganic additive and 1 to 15 parts by weight of a vulcanizing agent, with respect to 100 parts by weight of a butyl rubber; the pneumatic tire can reduce internal noise by distributing noise energy, causing generation of resonance in the tire, or changing the generated frequency without a risk of shear deformation generated between the sound-absorbing material and the tire.

Description

technical field [0001] The present invention relates to a pneumatic tire and its manufacturing method. More specifically, by dispersing the noise energy that causes resonance inside the tire or changing the frequency of occurrence without worrying about the shear strain that occurs between the sound-absorbing material for noise reduction and the tire, Pneumatic tire capable of reducing tire internal noise and its manufacturing method. Background technique [0002] The resonance sound inside the tire is the noise generated inside the tire, and automobile and tire manufacturers are paying attention to this noise recently. In the case of pneumatic tires, when driving on an uneven road surface, the pressure change inside the tire due to the uneven road surface is one of the causes of this noise, which is transmitted through the car body, thereby generating a sharp sound in the car, which brings the driver passenger discomfort and reduce ride comfort. As tires mounted on automo...
