PNEUMATIC TIRE WITH TIRE LAYER AND DVA BARRIER LAYER ADHERED THERETO AND METHOD OF MAKING SAME
First Claim
1. A pneumatic tire comprising:
- an outer tread;
a barrier layer disposed inwardly of the outer tread and including a dynamically vulcanized alloy, which comprises an engineering resin as a continuous phase and at least a partially vulcanized rubber as a dispersed phase, the barrier layer including an inner surface and an outer surface; and
a tire layer situated adjacent at least one of the inner or outer surfaces of the barrier layer, the tire layer including a rubber formulation comprising;
100 parts of natural rubber, a synthetic rubber, or blends or combinations thereof;
about 1-10 phr of a melamine derivative; and
at least one reinforcing filler;
wherein the tire is devoid of an adhesive layer between the barrier layer and the tire layer, and wherein the tire layer adheres directly to the barrier layer after tire cure.

Abstract
A pneumatic tire and method of making is disclosed, which includes, in one embodiment, an outer tread and a barrier layer disposed inwardly of the outer tread. The barrier layer includes a dynamically vulcanized alloy, which has an engineering resin as a continuous phase and at least a partially vulcanized rubber as a dispersed phase, and an inner surface and an outer surface. A tire layer, e.g., a ply layer, is situated adjacent at least one of the inner or outer surfaces of the barrier layer. The tire layer includes a rubber formulation having 100 parts of natural rubber, a synthetic rubber, or blends or combinations thereof, 1-10 phr of a melamine derivative, e.g., hexamethoxymethylmelamine, and at least one reinforcing filler. The tire is devoid of an adhesive layer between the barrier layer and the tire layer, and the tire layer adheres directly to the barrier layer after tire cure.

18. A method of making a pneumatic tire comprising:
-
positioning a tire layer and a barrier layer including a dynamically vulcanized alloy on a tire-building apparatus, the dynamically vulcanized alloy including an engineering resin as a continuous phase and at least a partially vulcanized rubber as a dispersed phase, the barrier layer including an inner surface and an outer surface, the tire layer situated adjacent at least one of the inner or outer surfaces of the barrier layer, the tire layer including a rubber formulation comprising; 100 parts of natural rubber, a synthetic rubber, or blends or combinations thereof; 1-10 phr of a melamine derivative; and at least one reinforcing filler; and disposing outwardly of the tire layer and barrier layer an outer tread to define an uncured tire assembly, wherein the tire assembly is devoid of an adhesive layer between the barrier layer and the tire layer and wherein the tire layer adheres directly to the barrier layer after tire cure. - View Dependent Claims (19)
