Title:
SEALANT FOR PREVENTION OF BLOWOUT, TUBELESS TIRE, AND TIRE TUBE
Document Type and Number:
WIPO Patent Application WO/2001/077251
Kind Code:
A1
Abstract:
A sealant for prevention of blowout (7) having such a property that is easy to flow due to a low viscosity while a vehicle is traveling and is difficult to flow due to a high viscosity while the vehicle is left stationary, wherein the viscosity of the sealant for prevention of blowout (7) filled in a sealant compartment (6) formed along the outer periphery of the air chamber (5) of a tire (T) is set at 25 to 35 dPa.s and a thixotropy value thereof is set at 6.5 to 11.0, whereby the viscosity of the sealant (7) is lowered by the agitating action due to vibration or by a centrifugal force when the tire (T) is rotated by the traveling of the vehicle so as to uniformly distribute the sealant into the sealant chamber (6), the viscosity of the sealant (7) is increased when the vehicle stops and the agitating action is eliminated and, because the sealant (7) is maintained in the state where the sealant (7) is diffused uniformly without being flown to the lower side of the sealant chamber (6) by the gravity, vibration and noise can be prevented even when the vehicle travels at a high speed after a long period of time is elapsed.
