Laminate gas barrier layer for pneumatic tires

摘要

The invention provides a laminate suitable for use with a pneumatic tire having an inner liner or like air-impermeable layer capable of, for example, maintaining a requisite air pressure. The laminate I of the invention includes laminated films and a rubber layer (R), the laminated films being made of a gas barrier layer (A) and an adhesive layer (B), the layer (B) being provided on at least one side of the layer (A), the layer (A) being formed of at least one member selected from polyamide resins, polyester resins, polyarylate resins, polyamide-based alloys and polyester-based alloys, the laminated films being irradiated in at least one periphery with an electron beam, and the adhesive layer (B) being heat-bonded to the rubber layer (R). The laminate II of the invention includes laminated films and a rubber layer (R), the laminated films being made of a rubber-adhering layer (D), an adhesive layer (B) and a gas barrier layer (A), the layers (D), (B) and (A) being laminated in this order with a structure of at least three layers, the rubber-adhering layer (D) being formed of at least one polyolefin resin, the gas barrier layer (A) being formed of at least one member selected from polyamide resins, polyester resins, polyarylate resins, polyamide-based alloys and polyester-based alloys, the laminated films being irradiated in at least one periphery with an electron beam, and the rubber-adhering layer (D) being heat-bonded to the rubber layer (R).
