Abstract

A method of effecting an improved adhesive bond between a rubber surface and a device adhered thereto is disclosed. In pneumatic tires, monitoring devices are more securely adhered to the innerliner of the tire utilizing a room temperature vulcanizable adhesive wherein curing is facilitated in the presence of moisture. The innerliner formulation is prepared by incorporating a material which has incomplete compatibility with the rubber of the innerliner formulation, and which has hygroscopic properties which thereby tends to attract moisture.

Claims

1. A tire comprising:

an innerliner comprising a first rubber material having a first rubber surface;

a strip material comprising a second rubber material having a second rubber surface, the first or the second rubber material including a rubber selected from the group consisting of homopolymers and copolymers of at least one of isoprene and 1,3-butadiene and copolymers of at least one of isoprene and 1,3-butadiene with styrene, a halogenated isobutylene-based copolymer with from about 2 to about 8 weight percent units derived from isoprene, and mixtures thereof, and

sorbitan monostearate; and

an adhesive that is situated between and in direct contact with the first and the second rubber surfaces of the first and the second rubber materials, the adhesive being vulcanizable at room temperature in the presence of moisture and selected from the group consisting of a urethane adhesive with silane type end groups, a hydroxyl terminated organosiloxane adhesive, and mixtures thereof.

2. The tire of claim 1 further including a microprocessor, an antenna, or both positioned onto the adhesive opposite an area of contact between the adhesive and the second rubber surface.

3. The tire of claim 1 wherein the adhesive is a hydroxyl terminated organosiloxane adhesive.
