Pneumatic tire with built-in colored sealant layer and method of preparing said pneumatic tire |
摘要 |
<p>The present invention relates to a pneumatic tire with a built-in sealant layer having a color other than black. The sealant layer is derived from a sealant precursor layer comprised of a butyl rubber, organoperoxide and silica together with a colorant. The butyl rubber-based precursor sealant layer is built into the tire to form a tire assembly and its butyl rubber component is depolymerized during a subsequent curing of the tire at an elevated temperature in a suitable mold to form the tire having the resultant built-in colored sealant layer. The sealant precursor composition may additionally contain clay and/or calcium carbonate.</p> |
