Title:
SEALANT MATERIAL COMPOSITION, AND TIRE USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/158250
Kind Code:
A1
Abstract:
A sealant material composition according to the present invention is obtained by mixing, with respect to 100 parts by mass of (A) a rubber component: at least 5 parts by mass of (B) a tackifier; at least 60 parts by mass of (C) a plasticizer; 0.1-10 parts by mass of (D) sulfur; and 0.1-10 parts by mass of (E) a vulcanization accelerator (where a thiuram-based vulcanization accelerator is excluded). Accordingly, the sealing property and viscosity-temperature dependence of the sealant material composition can be improved, and the flowability of the sealant material composition during tire storage can also be ameliorated.
