Abstract

A linoleum flooring product in one embodiment includes a linoleum substrate and a printed wear layer comprising a decorative indicia. The printed wear layer includes a wear layer and an ink print layer. The linoleum substrate may include a base linoleum layer applied on a backing material, and in some embodiments further includes a visual linoleum layer formed on top of the base linoleum layer. The printed wear layer may be adhesively bonded onto the linoleum substrate. In one embodiment, an ultraviolet curable adhesive may be used. A related method for forming the linoleum flooring product is also provided.

First claim

What is claimed is:

1. A method for forming a printed linoleum product, the method comprising:
providing a linoleum substrate formed in a first fabrication process, the linoleum substrate including at least one linoleum layer bonded to a backing layer;
providing a printed wear layer comprising a inked decorative indicia formed in a second fabrication process separate from the first fabrication process, the printed wear layer including a wear layer, which is substantially transparent, and an ink print layer;
applying a UV-curable adhesive onto the linoleum substrate;
partially curing the adhesive for a first period of time sufficient to produce a tacky condition by treating the adhesive with a first UV light source;
laminating the linoleum substrate with partially cured adhesive and the printed wear layer together to form a laminate; and
curing the adhesive for a second period of time sufficient to cure the adhesive by treating the laminate with a second UV light source exposed through the printed wear layer, wherein the printed wear layer becomes permanently bonded to the linoleum substrate.

2. The method of claim 1 , further comprising a step of forming a high performance protective top layer on top of the primed wear layer for durability.

3. The method of claim 2 , wherein the high performance protective top layer is formed of a high performance UV curable coating.

4. The method of claim 3 , wherein the printed wear layer comprises a wear layer formed of polyethylene terephtalate glycol-modified.

5. The method of claim 1 , wherein the linoleum substrate includes a base linoleum layer and a visible linoleum layer formed on top of the base linoleum layer.

6. The method of claim 5 , wherein the visible linoleum layer includes additive decorative components selected from the group consisting of colored particles, granules, chips, and flakes.

7. The method of claim 1 , wherein the printed wear layer comprises a wear layer formed of polyethylene terephtalate glycol-modified.

8. The method of claim 1 , wherein the decorative indicia is disposed below the wear layer and visible through the wear layer.

9. The method of claim 1 , further comprising heating the linoleum substrate prior to laminating.

10. The method of claim 1 , further comprising a pad layer ink printed with the decorative indicia, the printed pad layer being bonded to a bottom surface of the wear layer.

11. The method of claim 1 , further comprising heating the printed wear layer prior to laminating.

12. The method of claim 1 , wherein the curing steps include exposing the adhesive to ultraviolet light.

13. A method for forming a printed linoleum product, the method comprising:
providing a linoleum substrate formed in a first fabrication process, the linoleum substrate including at least one linoleum layer bonded to a backing layer;
providing a printed wear layer comprising an decorative indicia formed in a second fabrication process separately from the first fabrication process, the printed wear layer including a wear layer, which is substantially transparent, and an ink print layer;
applying an ultraviolet curable adhesive onto the linoleum substrate;
exposing the adhesive to a first ultraviolet light source for a period of time sufficient to partially cure the adhesive and produce a tacky condition;
laminating the linoleum substrate with partially cured adhesive and the printed wear layer together to form a laminate; and
exposing the adhesive to a second ultraviolet light source directed to the printed wear layer of the laminate for a period of time sufficient to fully cure the adhesive, wherein the printed wear layer becomes permanently bonded to the linoleum substrate.

14. The method of claim 13 , further comprising a step of forming a high performance protective top layer on top of the printed wear layer fear durability.

15. The method of claim 14 , wherein the high performance protective top layer is formed of polyester based acrylated urethane and the printed wear layer comprises a wear layer formed of polyethylene terephtalate glycol-modified.

16. The method of claim 13 , wherein the linoleum substrate includes a base linoleum layer and a visible linoleum layer formed on top of the base linoleum layer.

17. The method of claim 16 , wherein the visible linoleum layer includes additive decorative components selected from the group consisting of colored particles, granules, chips, and flakes.

18. The method of claim 13 further comprising heating the printed wear layer prior to laminating.

19. The method of claim 13 , further comprising heating the linoleum substrate prior to laminating.

20. The method of claim 13 , wherein the printed wear layer comprises a wear layer formed of polyethylene terephtalate glycol-modified.

21. The method of claim 13 , wherein the decorative indicia is disposed below the wear layer and visible through the wear layer.

22. The method of claim 13 , further comprising a pad layer ink printed with the decorative indicia, the printed pad layer being bonded to a bottom surface of the wear layer.

23. The method of claim 13 , wherein an ultraviolet curable ink is used to create the decorative indicia.

24. The method of claim 13 , wherein the linoleum layer includes only a single linoleum base layer without additive decorative components, the printed wear layer being adhesively bonded directly to the base layer.
