摘要

The present invention discloses a tire sealant and a preparation method thereof. The tire sealant comprises a solvent of 35%-95%, PVA gel of 0.05%-10%, block particles of 0.01%-5% and an additive of 0.1%-10%. The tire sealant can also comprise chitosan gel of 0.01%-5%. The method comprises the following steps: S1. polymer material particles are dissolved and precipitation is controlled to form suspended gel material in a liquid medium; S2. An additive is added into the liquid medium; and S3. block particles are added into the liquid medium containing the suspended gel material. When using the tire sealant and its preparation method in the present invention, the puncture formed by a spike with a diameter equal to or less than 6.35 mm can be sealed. Besides, the broken hole can be repaired between −40□ and 70□, and the sealing time can last for more than 48 hours.
