Abstract

The methods include treatment of the lower surface of inner liner surface with a rubber-containing liquid to produce a rubber-containing film thereupon.
Claims20
A method for producing a tire comprising a cured inner liner and at least one component positioned radially inward of the cured inner liner, the method comprising:
- a. providing a tire body comprising a cured inner liner comprising rubber, a majority of which comprises butyl rubber (optionally halogenated), wherein the cured inner liner comprises an upper and a lower surface with the lower surface positioned radially inward within the tire;
- b. treating the lower surface of the cured inner liner with a rubber-containing liquid wherein the rubber-containing liquid comprises at least one conjugated diene monomer-containing rubber, polyurethane and at least one solvent;
- c. allowing the rubber-containing liquid to dry upon the treated lower surface of the cured inner liner, thereby producing a rubber-containing film upon the lower surface of the cured inner liner;
- and
- d. adhering the component to the rubber-containing film upon the lower surface of the cured inner liner.
A cured tire comprising a tire body, a cured inner liner, and at least one component positioned radially inward of the cured inner liner,
- the cured inner liner comprising rubber, a majority of which comprises butyl rubber (optionally halogenated),
- wherein the cured inner liner has an upper surface and a lower surface with the lower surface positioned radially inward within the tire and,
- the lower surface of the cured inner liner includes a rubber-containing film comprising at least one conjugated diene monomer-containing rubber and polyurethane, and
- the rubber-containing film has a thickness of about 0.1 to about 25 micrometers, and
- the at least one component positioned radially inward of the cured inner liner is adhered to the rubber-containing film of the lower surface of the cured inner liner.
