Abstract

Identification labels and their incorporation in rubber-based articles are described. The labels include RFID components and can be incorporated in tires. The labels can withstand the relatively harsh conditions associated with vulcanization.

First claim

What is claimed is:

1. A tire tracking label comprising:
at least one face layer;
optionally, at least one primer layer;
at least one adhesive layer comprising unsaturated rubber, wherein upon contact between the adhesive layer and a green rubber-based article, and subsequent vulcanization of the rubber-based article, the adhesive crosslinks with the rubber to thereby form a permanent bond between the label and the rubber-based article; and
at least one RFID component.

2. The tire tracking label of claim 1 further comprising:
at least one release liner contacting the adhesive layer.

3. The tire tracking label of claim 1 wherein the face layer can withstand cold vulcanization without face layer degradation.

4. The tire tracking label of claim 1 wherein the face layer includes materials having melting points greater than 90° C.

5. The tire tracking label of claim 1 wherein the face layer includes at least one material selected from the group consisting of polyolefins, polyethylene terephthalate (PET), polyamides (PA), polyimides (PI), polyethylene naphthalate (PEN), cotton, paper, fiberglass, synthetic textiles, and combinations thereof.

6. The tire tracking label of claim 1 wherein the face layer can withstand warm vulcanization without face layer degradation.

7. The tire tracking label of claim 1 wherein the face layer includes materials having melting points greater than 170° C.

8. The tire tracking label of claim 1 wherein the face layer includes at least one material selected from the group consisting of polypropylene (PP), polyethylene terephthalate (PET), polyamides (PA), polyimides (PI), polyethylene naphthalate (PEN), cotton, paper, fiberglass, synthetic textiles, and combinations thereof.

9. The tire tracking label of claim 1 wherein the label comprises at least one primer layer disposed on the face layer.

10. The tire tracking label of claim 9 wherein the face layer is in the form of a film.

11. The tire tracking label of claim 1 wherein the label is free of a primer layer.

12. The tire tracking label of claim 11 wherein the face layer is in the form of a nonwoven.

13. The tire tracking label of claim 1 wherein the adhesive is a heat-activated adhesive.

14. The tire tracking label of claim 13 wherein the heat-activated adhesive has a heat activation temperature within a range of from 90° C. to 170° C.

15. The tire tracking label of claim 13 wherein the heat-activated adhesive has a heat activation temperature greater than 170° C.

16. The tire tracking label of claim 1 wherein the adhesive is a multiphase adhesive.

17. The tire tracking label of claim 1 wherein the adhesive is a multistage adhesive.

18. The tire tracking label of claim 17 wherein the multistage adhesive exhibits pressure sensitive adhesive characteristics at a first stage.

19. The tire tracking label of claim 18 wherein the multistage adhesive exhibits permanent adhesive characteristics at a second stage.

20. The tire tracking label of claim 19 wherein the multistage adhesive transitions from the first stage to the second stage upon heating or exposure to radiation.

21. The tire tracking label of claim 1 wherein the RFID component includes a passive RFID device.

22. The tire tracking label of claim 1 wherein the RFID component includes an antenna.

23. The tire tracking label of claim 1 wherein the label includes two primer layers both disposed between the face layer and the adhesive layer.

24. The tire tracking label of claim 1 wherein the adhesive layer is disposed between the primer layer and the RFID component.

25. The tire tracking label of claim 1 wherein the RFID component is disposed between the face layer and the adhesive layer.

26. The tire tracking label of claim 1 wherein the RFID component is disposed between the face layer and the primer layer.

27. The tire tracking label of claim 1 wherein the RFID component is disposed between the primer layer and the adhesive layer.

28. The tire tracking label of claim 1 wherein the label comprises two face layers, and the RFID component is disposed between the two face layers.

29. The tire tracking label of claim 28 wherein the RFID component is disposed between a face layer and an adhesive layer.

30. The tire tracking label of claim 28 wherein the label also comprises two adhesive layers, the RFID component is disposed between the two adhesive layers.

31. The tire tracking label of claim 1 wherein the label comprises two adhesive layers and two primer layers one of which is adjacent to a first layer of adhesive.

32. The tire tracking label of claim 31 wherein the RFID component is disposed between a layer of primer and a second layer of adhesive.

33. The tire tracking label of claim 31 wherein label includes at least one release liner and the RFID component is disposed between an adhesive layer and the release liner.

34. The tire tracking label of claim 31 wherein the RFID component is disposed between a face layer and layer of primer.

35. A labeled rubber-based article comprising:
a rubber-based article;
a label including at least one face layer; optionally, at least one primer layer; at least one adhesive layer; and at least one RFID component;
wherein the adhesive layer comprises unsaturated rubber, wherein upon contact between the adhesive layer and a green rubber-based article, and subsequent vulcanization of the rubber-based article, the adhesive crosslinks with the rubber to thereby form a permanent bond between the label and the rubber-based article; and
wherein the label is affixed to the article.

36. The labeled article of claim 35 wherein the face layer can withstand cold vulcanization without face layer degradation without face layer degradation.

37. The labeled article of claim 35 wherein the face layer includes materials having melting points greater than 90° C.

38. The labeled article of claim 35 , wherein the face layer includes at least one material selected from the group consisting of polyolefins, polyethylene terephthalate (PET), polyamides (PA), polyimides (PI), polyethylene naphthalate (PEN), cotton, paper, fiberglass, synthetic textiles, and combinations thereof.

39. The labeled article of claim 35 wherein the face layer can withstand warm vulcanization without face layer degradation without face layer degradation.

40. The labeled article of claim 35 wherein the face layer includes materials having melting points greater than 170° C.

41. The labeled article of claim 35 wherein the face layer includes at least one material selected from the group consisting of polypropylene (PP), polyethylene terephthalate (PET), polyamides (PA), polyimides (PI), polyethylene naphthalate (PEN), cotton, paper, fiberglass, synthetic textiles, and combinations thereof.

42. The labeled article of claim 35 wherein the label comprises at least one primer layer disposed on the face layer.
