LOW-NOISE TIRE, TIRE INNER POLYURETHANE FOAM SOUND-ABSORBING LINING COMPOSITION FOR MANUFACTURING SAME, AND TIRE INNER POLYURETHANE FOAM SOUND-ABSORBING LINING METHOD USING SAME

The present invention relates to a low-noise tire, a tire inner polyurethane foam sound-absorbing lining composition for manufacturing same, and a tire inner polyurethane foam sound-absorbing lining method using same. More specifically, the present invention relates to a low-noise tire, a tire inner polyurethane foam sound-absorbing lining composition for manufacturing same, and a tire inner polyurethane foam sound-absorbing lining method using same, wherein in order to reduce cavity resonance noise, which occurs as vibration forces generated between the tire tread and road surface are transmitted to the cavity space inside the tire and the axle, leading to interior noise, a liquid foaming polyurethane composition is conveniently, rapidly, and precisely applied in a liquid foam spraying manner to the inner surface of the tire, which corresponds to the tire tread, and cured to form a polyurethane sound-absorbing lining, whereby the low-noise tire exhibits improved low-noise performance.
