Abstract

An assembly for use in or on a tire. The assembly comprises an electronic device having a body and an adhesive coating on at least the body of the electronic device. The body is at least partially made of a plastic material or a fiber reinforced plastic (FRP). The adhesive coating comprises an imide-based adhesive. The adhesive coating may have a polymer bonding group comprising at least one of natural rubber, butyl rubber, a chlorinated elastomer, polybutadiene, synthetic polyisoprene, or styrene-butadiene rubber or a combination thereof. In one embodiment, the assembly further comprises a first elastomeric layer and a second elastomeric layer. The adhesive coating secures the body to the first and the second elastomeric layers. The first and second elastomeric layers may comprise a butyl-containing compound or natural rubber compound. In one embodiment, the electronic device is a radio frequency identification tag having the body and an antenna.

Claims

1. An assembly for use on a tire having a tire wall, the assembly comprising:

an electronic device having a body being at least partially made of a plastic material; and

an adhesive coating on the body of the electronic device for securing the body to the tire wall, the adhesive coating comprising an imide-based adhesive.

2. The assembly of claim 1 wherein the adhesive coating has a polymer bonding group comprising at least one of natural rubber, a chlorinated elastomer, butyl rubber, styrene-butadiene, polybutadiene, synthetic polyisoprene or a combination thereof.

3. The assembly of claim 1 wherein the adhesive coating is substantially isocyanate free.

4. The assembly of claim 1 wherein the adhesive coating further comprises a zinc-containing compound.

5. The assembly of claim 1 wherein the adhesive coating further comprises a selenium-containing compound.

6. The assembly of claim 1 further comprising:

a first elastomeric layer; and

a second elastomeric layer, the first and second elastomeric layers comprising a butyl-containing compound, wherein the electronic device is positioned between the first and second elastomeric layers with the adhesive coating securing the body to the first and second elastomeric layers.

7. The assembly of claim 6 wherein a thickness of the first elastomeric layer and the second elastomeric layer taken through a center of the assembly is greater than a thickness taken along a portion of a periphery of the assembly.

8. The assembly of claim 6 further comprising:

a tie-gumstrip layer on the first elastomeric layer on the side opposite the second elastomeric layer for securing the assembly to an innerliner of the tire.

9. The assembly of claim 8 wherein the first elastomeric layer and the second elastomeric layer are at least partially cured.

10. The assembly of claim 1 further comprising:

a first elastomeric layer; and

a second elastomeric layer, the first and second elastomeric layers comprising a natural rubber compound, wherein the electronic device is positioned between the first and second elastomeric layers with the adhesive coating securing the body to the first and second elastomeric layers.

11. A tire comprising:

a tire wall; and

an assembly affixed to the tire wall, the assembly comprising;

an electronic device having a body being at least partially made of a plastic material; and

an adhesive coating on the body of the electronic device for securing the body to the tire wall, the adhesive coating comprising an imide-based adhesive.

12. The tire of claim 11 wherein the adhesive coating has a polymer bonding group comprising at least one of natural rubber, a chlorinated elastomer, butyl rubber, styrene-butadiene rubber, polybutadiene or synthetic polyisoprene or a combination thereof.

13. The tire of claim 11 wherein the adhesive coating is substantially isocyanate free.

14. The tire of claim 11 wherein the adhesive coating further comprises:

at least one of a zinc-containing compound or a selenium-containing compound or a combination thereof.

15. The tire of claim 11 wherein the assembly further comprises:

a first elastomeric layer; and

a second elastomeric layer, the first and second elastomeric layers comprising a butyl-containing compound, wherein the electronic device is positioned between the first and second elastomeric layers with the adhesive coating securing the body to the first and second elastomeric layers.

16. The tire of claim 15 wherein the assembly further comprises:

a tie-gumstrip layer on the first elastomeric layer on the side opposite the second elastomeric layer for securing the assembly to an innerliner of the tire wall.

17. The tire of claim 16 wherein the first elastomeric layer and the second elastomeric layer are at least partially cured.

18. The tire of claim 15 wherein a thickness of the first elastomeric layer and the second elastomeric layer taken through a center of the assembly is greater than a thickness taken along a portion of a periphery of the assembly.

19. The tire of claim 11 wherein the assembly further comprises:

a first elastomeric layer; and

a second elastomeric layer, the first and second elastomeric layers comprising a natural rubber compound, wherein the electronic device is positioned between the first and second elastomeric layers with the adhesive coating securing the body to the first and second elastomeric layers.

20. A tire comprising:

a tire wall; and

an assembly affixed to the tire wall, the assembly comprising;

a first elastomeric layer;

a second elastomeric layer, wherein the first and the second elastomeric layers are selected from a group consisting of a butyl-containing compound and a natural rubber compound;

an RFID tag between the first elastomeric layer and the second elastomeric layer, the RFID tag having a body and an antenna, the body being at least partially made of a plastic material; and

an imide-based adhesive coating on at least the body of the RFID tag for securing the body to the first and the second elastomeric layers, the imide-based adhesive coating comprising at least one of a zinc-containing compound or a selenium-containing compound or combinations thereof and a polymer bonding group comprising at least one of natural rubber, a chlorinated elastomer, butyl rubber, styrene-butadiene, polybutadiene, or synthetic polyisoprene or a combination thereof.
