Environmentally resistant assembly containing an electronic device for use in a tire
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.
1. An assembly for use on a tire having a tire wall, the assembly comprising:
a first elastomeric layer and a second elastomeric layer, wherein the first and second elastomeric layers comprise a butyl-containing compound or a natural rubber compound, and wherein the first and second elastomeric layers are configured with each elastomeric layer having a reduced step-off to define a tapered edge;
an electronic device having a body being at least partially made of a plastic material, wherein the electronic device is positioned between the first and second elastomeric layers;
an adhesive coating on the body of the electronic device that secures the body to the first and second elastomeric layers, the adhesive coating comprising an imide-based adhesive; and
a tie-gumstrip layer on the first elastomeric layer on a side opposite the second elastomeric layer for securing the assembly to an innerliner of the tire.
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 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 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.
7. The assembly of claim 1 wherein the first elastomeric layer and the second elastomeric layer are at least partially cured.
8. A tire comprising:
a tire wall; and
an assembly affixed to the tire wall, the assembly comprising:
a first elastomeric layer and a second elastomeric layer, wherein the first and second elastomeric layers comprise a butyl-containing compound or a natural rubber compound, and wherein the first and second elastomeric layers are configured with each elastomeric layer having a reduced step-off to define a tapered edge;
an electronic device having a body being at least partially made of a plastic material, wherein the electronic device is positioned between the first and second elastomeric layers; and
an adhesive coating on the body of the electronic device that secures the body to the first and second elastomeric layers, the adhesive coating comprising an imide-based adhesive; and
a tie-gumstrip layer on the first elastomeric layer on a side opposite the second elastomeric layer for securing the assembly to an innerliner of the tire.
9. The tire of claim 8 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.
10. The tire of claim 8 wherein the adhesive coating is isocyanate free.
11. The tire of claim 8 wherein the adhesive coating further comprises:
at least one of a zinc-containing compound or a selenium-containing compound or a combination thereof.
12. The tire of claim 8 wherein the first elastomeric layer and the second elastomeric layer are at least partially cured.
13. The tire of claim 8 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.
14. 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, wherein the first and second elastomeric layers are configured with each elastomeric layer having a reduced step-off to define a tapered edge;
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;
an imide-based adhesive coating on at least the body of the RFID that secures 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; and
a tie-gumstrip layer on the first elastomeric layer on a side opposite the second elastomeric layer for securing the assembly to an innerliner of the tire.
