Abstract

A self bonding floor tile includes a main body and a self bonding layer connected with the main body. The self bonding layer includes an absorptive element, a first adhesive and a second adhesive. The first adhesive connects the main body with the self bonding layer. The absorptive element includes a plurality of fibers which are implanted into the first adhesive by flocking process with at least a portion of the absorptive element extending into the first adhesive, and at least a portion of the second adhesive penetrates into the other portion of the absorptive element for connecting the self bonding layer with a support body going to be decorated. The present self bonding floor tile can be quickly installed, easily and partly replaced with low installation and replacement cost.

Claims (27)

1. A self bonding floor tile, comprising:

a main body having a concave and convex texture at its bottom; and

a self bonding layer connected with the main body, and comprising an absorptive element, a first adhesive and a second adhesive, the first adhesive connecting the bottom of the main body with the self bonding layer, the absorptive element comprising a plurality of fibers with a length greater than a depth but smaller than a double depth of the concave and the fibers being implanted into the first adhesive with at least a portion of the absorptive element extending into the first adhesive and the other portion of the absorptive element extending beyond the first adhesive, and at least a portion of the second adhesive penetrating into the other portion of the absorptive element for connecting the self bonding layer with a support body which could be decorated by a plurality of the self bonding floor tiles.

2. The self bonding floor tile according to claim 1 , wherein the absorptive element is added to the first adhesive after the first adhesive is spread over the main body and is secured to the main body into a single piece after the first adhesive being cured, the second adhesive is spread over the absorptive element after the absorptive element is added to the first adhesive.

3. The self bonding floor tile according to claim 2 , wherein an adhesion between the first adhesive and the main body is greater than an adhesion between the second adhesive and the support body after the first adhesive is cured.

4. The self bonding floor tile according to claim 1 , wherein the absorptive element is cotton fiber, glass fiber, synthetic fiber, or blended fiber composed of at least two different fibers in a single fiber strand or yarn.

5. The self bonding floor tile according to claim 1 , wherein the first adhesive is acrylate adhesive, PVC paste resins, epoxy glue, phenol glue, vinyl adhesive, amino resin adhesive, or polyurethane adhesive, and the second adhesive is hot-melt pressure sensitive adhesive.

6. The self bonding floor tile according to claim 1 , wherein the main body includes a base layer, a decoration layer and a wear-resistant layer, the decoration layer is located above the base layer, the wear-resistant layer is located above the decoration layer, and the first adhesive is spread over the base layer.

7. The self bonding floor tile according to claim 6 , wherein the base layer, the decoration layer and the wear-resistant layer are formed into a single piece by hot-pressing method.

8. A self bonding floor tile, comprising:

a main body having a concave and convex texture at its bottom; and

a self bonding layer being disposed under and connected with the bottom of the main body, for connecting the self bonding floor tile with a support body which could be decorated by a plurality of the self bonding floor tiles;

the self bonding layer comprising an absorptive element, a first adhesive and a second adhesive, the first adhesive being in a solid-liquid mixing state at first, the absorptive element comprising a plurality of fibers with a length greater than a depth but smaller than a double depth of the concave, and at least a portion of the absorptive element being added into the first adhesive with another portion of the absorptive element extending beyond the first adhesive, the absorptive element being secured to the main body after the first adhesive being cured, at least a portion of the second adhesive penetrating into the another portion of the absorptive element after the first adhesive being cured.

9. The self bonding floor tile according to claim 8 , wherein the fibers are implanted into the first adhesive by flocking process.

10. The self bonding floor tile according to claim 9 , wherein the fiber is added to the first adhesive in a density of 10-100 gram fibers per square meter.

11. The self bonding floor tile according to claim 9 , wherein a length of the fiber is in a range of 0.05-10 mm, and a denier of the fiber is 1-10 D.

12. The self bonding floor tile according to claim 8 , wherein a thickness of the first adhesive and a thickness of the second adhesive are ⅕-⅘ of the thickness of the self bonding layer.

13. The self bonding floor tile according to claim 12 , wherein a thickness of the first adhesive is the same as a thickness of the second adhesive.

14. The self bonding floor tile according to claim 8 , wherein an adhesion between the first adhesive and the main body is greater than an adhesion between the second adhesive and the support body after the first adhesive is cured.

15. A self bonding floor tile assembly, comprising:

a self bonding floor tile and a support body which could be decorated by a plurality of the self bonding floor tiles, the self bonding floor tile comprising:

a main body having a concave and convex texture at its bottom; and

a self bonding layer being disposed under and connected with the main body, for connecting the self bonding floor tile with the support body, the self bonding layer comprising an absorptive element, a first adhesive and a second adhesive, the absorptive element comprising a plurality of fibers with a length greater than a depth but smaller than a double depth of the concave, the first adhesive being spread on the bottom of the main body, the fibers having one end embedded into the first adhesive, with at least a portion of the absorptive element extending beyond the first adhesive, the second adhesive penetrating into the at least a portion of the absorptive element.

16. The self bonding floor tile assembly according to claim 15 , wherein the fibers are added to the first adhesive in a density of 10-100 g/m 2 .

17. The self bonding floor tile assembly according to claim 15 , wherein a thickness of the first adhesive is the same as a thickness of the second adhesive.

18. The self bonding floor tile assembly according to claim 15 , wherein the absorptive element is added to the first adhesive after the first adhesive is spread over the main body and is secured to the main body into a single piece after the first adhesive being cured, and the second adhesive is spread over the absorptive element after the absorptive element is added to the first adhesive.

19. The self bonding floor tile assembly according to claim 15 , wherein an adhesion between the first adhesive and the main body is greater than an adhesion between the second adhesive and the support body after the first adhesive is cured.
