Abstract

An adhesive floor/wallboard includes a floor/wallboard main body layer and a buffer layer adhered to the back surface of the floor/wallboard main body layer. The buffer layer is provided with a plurality of holes. The holes extend through the buffer layer to the main body layer. Glue is deposited in the holes. The buffer layer is adhered to the back surface of the floor/wallboard. The glue in the holes makes direct contact with the floor/wallboard main body at the holes. Due to the holes and their depth, the contact area between the glue, the buffer layer and the main body is increased. Accordingly, the adhesive floor/wallboard can be more firmly adhered to a backing surface.

Claims (16)

1. An adhesive floor/wallboard comprising a floor/wallboard main body layer, and a buffer layer adhered to the back surface of the floor/wallboard main body layer, wherein the buffer layer is provided with a plurality of holes, the holes extend through the buffer layer to the main body layer, wherein a portion of the back surface of the floor/wallboard main body layer is not covered by the buffer layer, and wherein the buffer layer comprises irradiation cross-linked polyethylene (IXPE).

2. The adhesive floor/wallboard according to claim 1 , wherein the holes are at least one of round holes, elliptical holes, square holes and irregular holes, and the area of the holes is 25% to 75% of the area of the buffer layer.

3. The adhesive floor/wallboard according to claim 2 , wherein if the holes are round holes, elliptical holes, or square holes, the area of the holes is 35% to 75% of the area of the buffer layer.

4. The adhesive floor/wallboard according to claim 2 , wherein if the holes are irregular holes that are not round holes, elliptical holes, or square holes, the area of the holes is 25% of the area of the buffer layer.

5. The adhesive floor/wallboard according to claim 1 , wherein the buffer layer further comprises foamed polyvinyl chloride (PVC) or foamed ethylene vinyl acetate (EVA) or cork wood.

6. The adhesive floor/wallboard according to claim 5 , further comprising a self-adhesive layer and a release paper layer, wherein the self-adhesive layer is adhered to the back surface of the buffer layer, the release paper layer is adhered to the back surface of the self-adhesive layer, and the self-adhesive layer and the release paper layer are also provided with holes in the positions corresponding to the holes of the buffer layer.

7. The adhesive floor/wallboard according to claim 6 , wherein the thickness of the floor/wallboard main body layer is between 0.5 mm and 5 mm, and the thickness of the buffer layer is between 0.5 mm and 5 mm.

8. The adhesive floor/wallboard according to claim 6 , wherein the material of the floor/wallboard main body layer is at least one of wood board, a bamboo board, a high density PVC composite material, a glass magnesium plate, a high density fiberboard, a medium density fiberboard, an aluminum alloy material, a cement board, an aluminum-plastic board, textile, a paperboard, or an HPL fireproof board.

9. The adhesive floor/wallboard according to claim 1 , further comprising a self-adhesive layer and a release paper layer, wherein the self-adhesive layer is adhered to the back surface of the buffer layer, the release paper layer is adhered to the back surface of the self-adhesive layer, and the self-adhesive layer and the release paper layer are also provided with holes in the positions corresponding to the holes of the buffer layer.

10. The adhesive floor/wallboard according to claim 9 wherein the thickness of the floor/wallboard main body layer is 0.5-5 mm and the thickness of the buffer layer is between 0.5 mm and 5 mm.

11. The adhesive floor/wallboard according to claim 1 , wherein the material of the floor/wallboard main body layer is at least one of wood board, a bamboo board, a high density PVC composite material, a glass magnesium plate, a high density fiberboard, a medium density fiberboard, an aluminum alloy material, a cement board, an aluminum-plastic board, textile, a paperboard, and an HPL fireproof board.

12. The adhesive floor/wallboard according to claim 11 , wherein the thickness of the floor/wallboard main body layer is 0.5-5 mm and the thickness of the buffer layer is between 0.5 mm and 5 mm.

13. An adhesive floor/wallboard comprising a floor/wallboard main body layer, a buffer layer adhered to the back surface of the floor/wallboard main body layer, a self-adhesive layer, and a release paper layer,

wherein the self-adhesive layer is adhered to the back surface of the buffer layer, and the release paper layer is adhered to the back surface of the self-adhesive layer,

wherein the buffer layer, the self-adhesive layer, and the release paper layer are provided with a plurality of holes, the plurality of holes extend through the buffer layer, the self-adhesive layer, and the release paper layer all the way to the main body layer, and a portion of the back surface of the floor/wallboard main body layer is not covered by the buffer layer, and

wherein the material of the buffer layer comprises irradiation cross-linked polyethylene (IXPE).
