Abstract
The laminate according to the present invention includes a thermoplastic resin film-containing layer and a rubber layer, in which the rubber layer contains a modified diene polymer, and the rubber layer has a dynamic storage modulus E′ at −20° C. of 1.0×105 to 1.0×108 Pa. This laminate can improve the resistance to the fractures and the cracks of the inner liner.
Claims22
A laminate comprising:
- a thermoplastic resin film-containing layer and a rubber layer, wherein the rubber layer contains a modified diene polymer.
A method of producing a tire having a carcass, an inner liner formed of a thermoplastic resin film, a rubber layer disposed between the carcass and the inner liner, an adhesive layer bonding the inner liner to the rubber layer, the method comprising the steps of:
- applying the inner liner to the rubber layer with a dynamic storage modulus E′ at −20° C. of 1.0×105 to 1.0×107 Pa and a thickness of 0.1 to 1 mm through the adhesive layer to form a laminate;
- and
- disposing the laminate on the carcass so that the rubber layer in the laminate is opposed to the carcass disposed on a tire molding drum.
