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.

Claims

1. A method of affixing a label to a rubber-based article, the method comprising:

providing a rubber-based article;

providing a label including at least one face layer, optionally at least one primer layer, at least one adhesive layer comprising unsaturated rubber, and at least one RFID component; and

contacting the adhesive layer and a green rubber-based article; and

vulcanizing the rubber-based article, wherein during vulcanizing, the adhesive layer crosslinks with the rubber to thereby form a permanent bond between the label and the rubber-based article, thereby affixing the label to the rubber-based article.

2. The method of claim 1, wherein the label is embedded within the rubber-based article such that the label is at least partially hidden from view in the article.

3. The method of claim 1, wherein the label is embedded within the rubber-based article such that the label is hidden from view in the article.

4. The method of claim 1, wherein the label is affixed to the surface of rubber-based article.

5. The method of claim 1, wherein the face layer can withstand cold vulcanization without face layer degradation.

7. The method of claim 1, wherein the face layer is a film.

8. The method of claim 7, wherein the label comprises at least one primer layer disposed on the face layer.

9. The method of claim 8, wherein the face layer includes at least one material selected from the group consisting of polyolefins (e.g., polyethylene, polypropylene), polyethylene terephthalate (PET), polyamides (PA), polyimides (PI), polyethylene naphthalate (PEN), and combinations thereof.

10. The method of claim 1, wherein the face layer can withstand warm vulcanization without face layer degradation.

11. The method of claim 1, wherein the face layer includes materials having melting points greater than 170°

C.

12. The method of claim 1, wherein the face layer is a nonwoven layer.

13. The method of claim 12, wherein the nonwoven layer is selected from the group consisting of cotton, paper, fiberglass, synthetic textiles, and combinations thereof.

14. The method of claim 1, wherein the adhesive is a heat-activated adhesive.

15. The method of claim 14, wherein the heat-activated adhesive has a heat activation temperature within a range of from 90°

C. to 170°

C.

16. The method of claim 14, wherein the heat-activated adhesive has a heat activation temperature greater than 170°

C.

17. The method of claim 1, wherein the adhesive is a multiphase adhesive.

18. The method of claim 1, wherein the adhesive is a multistage adhesive.

19. The method of claim 18, wherein the multistage adhesive exhibits pressure sensitive adhesive characteristics at a first stage.

20. The method of claim 19, wherein the multistage adhesive exhibits permanent adhesive characteristics at a second stage.

21. The method of claim 20, wherein the multistage adhesive transitions from the first stage to the second stage upon heating or exposure to radiation.

22. The method of claim 1, wherein the adhesive is selected from the group consisting of an acrylic adhesive, a rubber-acrylic hybrid adhesive, and combinations thereof.

23. The method of claim 1, wherein the RFID component includes a passive RFID device.

24. The method of claim 1, wherein the RFID component includes an antenna.

25. The method of claim 1, wherein the label includes two primer layers both disposed between the face layer and the adhesive layer.

26. The method of claim 1, wherein the adhesive layer is disposed between the primer layer and the RFID component.

27. The method of claim 1, wherein the RFID component is disposed between the face layer and the adhesive layer.

28. The method of claim 1, wherein the RFID component is disposed between the face layer and the primer layer.

29. The method of claim 1, wherein the RFID component is disposed between the primer layer and the adhesive layer.

30. The method of claim 1, wherein the label comprises two face layers, and the RFID component is disposed between the two face layers.

31. The method of claim 30, wherein the RFID component is disposed between a face layer and an adhesive layer.

32. The method of claim 30, wherein the label also comprises two adhesive layers, the RFID component is disposed between the two adhesive layers.

33. The method 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.

34. The method of claim 33, wherein the RFID component is disposed between a layer of primer and a second layer of adhesive.

35. The method of claim 34, wherein label includes at least one release liner and the RFID component is disposed between an adhesive layer and the release liner.

36. The method of claim 1, wherein the rubber-based article is selected from the group consisting of a tire, suspension components, cushions, shoe soles, hoses, hockey pucks, conveyor belts, musical mouth pieces, and bowling balls.

6. The method of 1, wherein the face layer includes materials having melting points greater than 90°
