FIGS. 1 and 2 illustrate an adhesive or suction sheet 10 constructed in accordance with an embodiment of the present invention. The adhesive sheet 10 is adapted to be releasably attached to a support surface (e.g., any non-porous, substantially flat surface). The adhesive sheet 10 has a bonding side 12 adapted to be attached to an item (not show in FIGS. 1 and 2), such as a flooring or wall panel, so that the item can be releasably attached to the support surface via the adhesive sheet 10. An adhesive side 14 of the adhesive sheet 10, which is located opposite the bonding side 12, is adapted to be removably attached to the support surface. In one embodiment, the adhesive sheet 10 may be used as a stand-alone product. That is, the adhesive sheet 10 may be applied to the support surface by itself such that the item may be subsequently attached to the adhesive sheet 10, as will be discussed in greater detail below. In another embodiment, the item may be pre-laminated to the bonding side 12 of the adhesive sheet 10 and then applied to the support surface as a single unit. The construction and use of the adhesive sheet 10 are discussed in greater detail below.

The adhesive sheet 10 includes an elastic and/or flexible layer 16 having a plurality of holes 18 (see FIG. 2) provided throughout the elastic layer 16. In one embodiment, the elastic layer 16 is made from a foam material composed of ethylene vinyl acetate (EVA), which is a copolymer of ethylene and vinyl acetate. In other embodiments, the foam can be made from any suitable elastic material, such as rubber, plastic, urethane, polyurethane (PU), polyethylene (PE), polystyrene, vinyl, silicone, latex rubber, etc., or mixtures thereof.

In one embodiment, the elastic layer 16 may be formed from a mixture of EVA (e.g., in about 25%-35% by weight), PE (e.g., in about 25%-35% by weight) and/or PU (e.g., in about 5%-10% by weight). This mixture may optionally include other components, such as a filler (e.g., calcium carbonate and/or talcum powder) in about 20%-30% by weight, a foaming agent (e.g., azodicarbonamide), a crosslinking agent (e.g., dicumyl peroxide), a foaming promoter (e.g., zinc oxide) and/or a lubricating agent (e.g., stearic acid). In one embodiment, the mixture is chemically blended by heat and pressure in a mixer using at a suitable temperature and pressure to create a paste-like substrate. The paste-like substrate is then fed through an extruder and conveyor to form a substantially flat sheet of the blended material. Thereafter, the flat sheet is subjected to a foaming process by feeding same into a mold foaming vulcanizing machine at a suitable temperature and pressure. The flat sheet undergoes a vulcanization process to form a foamed sheet with a desired density, thickness, etc.

In one embodiment, the elastic layer 16 of the present invention provides a rubber foam-like in softness and flexibility. The material has low-temperature toughness, stress-crack resistance, waterproof properties, resistance to UV radiation, foam recovery from compression.

In one embodiment, the holes 18 are distributed randomly and substantially throughout the entire elastic layer 16. In another embodiment, the holes 18 can be distributed substantially uniformly in the elastic layer 16. In one embodiment, the holes 18 positioned in the interior of the adhesive sheet 10 (see, e.g., the holes labeled as “18a” in FIG. 3) are formed as closed cells such that air or other gas is encapsulated or trapped in the holes 18a. On the other hand, the holes positioned on the surfaces of the bonding and adhesive sides 12, 14 of the elastic layer 16 (see, e.g., the holes labeled as “18b” in FIG. 3) are open to the exterior of the elastic layer 16. In one embodiment, the holes 18b positioned on the adhesive side 14 of the elastic layer 16 each have a concave shape extending inwardly into the elastic layer 16 and are treated as discussed below such that they can provide and maintain suction against the support surface for releasably attaching the adhesive sheet 10 to same. In one embodiment, the holes 18b are spread substantially throughout the entire surface of the adhesive side 14 of the elastic layer 16.

In one embodiment, the holes 18 have random sizes. In one embodiment, at least some or substantially all of the holes 18 have a diameter greater than approximately 10 μm.

In another embodiment, at least some or substantially all of the holes 18 have a diameter greater than approximately 70 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter greater than approximately 80 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter greater than approximately 90 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter greater than approximately 100 μm.

In one embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 1 mm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 900 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 800 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 700 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 600 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 500 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 400 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 300 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 200 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter less than approximately 100 μm.

In one embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 10 μm to approximately 250 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 20 μm to approximately 240 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 30 μm to approximately 230 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 40 μm to approximately 220 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 50 μm to approximately 210 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 60 μm to approximately 200 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 70 μm to approximately 190 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 75 μm to approximately 180 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 75 μm to approximately 170 μm. In another embodiment, at least some or substantially all of the holes 18 have a diameter ranging from approximately 75 μm to approximately 160 μm.

The elastic layer 16 can have a varying density, depending on various factors and variables, such as the number and size of the holes 18. In one embodiment, the density of the elastic layer 16 ranges from about 30 kg/m³ to about 280 kg/m³. In other embodiments, the density of the elastic layer 16 can be less than about 30 kg/m³ or greater than about 280 kg/m³.

The elastic layer 16 can also have a thickness that can vary depending on various factors, such as types of item for attachment to the adhesive sheet 10. In one embodiment, the elastic layer 16 ranges in thickness from about 0.1 mm to about 5 mm. In other embodiments, the thickness of the elastic layer 16 can be greater than about 5 mm or smaller than about 0.1 mm. In another embodiment, the thickness of the elastic layer 16 is greater than the largest diameter or radius of the holes 18 so as to ensure that the interior surfaces of the holes 18b provided on the adhesive side 14 of the elastic layer 16 are completely closed or sealed.

In one embodiment, a coating of sealing material 20 is applied to the outer surface of the elastic layer 16 on the adhesive side 14 of the adhesive sheet 10. The sealing material can be any suitable sealing material capable of providing a substantially air-tight seal to the interior surfaces of the holes 18b and/or around edges or lips 22 (see FIG. 3) surrounding the holes 18b. In this manner, the holes 18b are adapted to function as micro-suction holes for releasably attaching the adhesive sheet 10 to a non-porous, substantially flat surface. In one embodiment, the sealing material includes polyurethane (“PU”).

In one embodiment, the adhesive sheet 10 also includes a primer coating 24 applied to the outer surface of the elastic layer 16 on the bonding side 12 of the adhesive sheet 10. More particularly, the primer coating 24 can be any suitable material known to persons of ordinary skill in the art. A layer of bonding material 26 is also applied to the primer coating 24. The bond layer 26 can be any suitable material known to persons of ordinary skill in the art for securely or fixedly bonding the adhesive sheet 10 to another item. Optionally, protective films 28, 30 (e.g., peel-off paper liners) are applied over the bonding layer 26 and the sealing coating 20, respectively, to protect same during storage and/or transportation.

In one embodiment, a method is provided for making the adhesive sheet 10. The adhesive sheet 10 can be made from a foam 32 (see FIG. 5), such as an EVA foam, which is made in a manner known in the art. In one embodiment, the foam 32 may be purchased from a foam manufacturer, such as Foamtech LTD, located Shanghai City, China. The foam 32 is then cut into a plurality of sheets 34 in desired thicknesses, as indicated by dotted-line representation in FIG. 5. The sheets 34 are then attached (e.g., glued) to each other in an end-to-end fashion so as to create a substantially continuous foam sheet rolled into a roll for easy storage and/or transportation. At this stage, the sheet 34 has a construction similar or corresponding to that of the elastic layer 16 shown in FIGS. 2 and 3. That is, the sheet 34 has a plurality of open holes 18b formed on each outer side or surface thereof (see FIG. 7A). The sealing layer 20, the primer coating 24 and the bonding layer 26 are applied to the sheet 34 in the following manner.

With reference to FIG. 6, the rolled foam sheet 34 is fed to a first roller applicator 36, which applies a primer coating 24 to one side of the sheet 34. The sheet 34 then passes through a first oven 38 so as to cure the primer coating 24 at a suitable temperature (e.g., at 100° C.). Thereafter, the sheet 34 is fed to a second roller applicator 40, which applies a bonding agent over the cured primer coating 24, and then passes through a second oven 42 to cure the bonding agent to form a bonding layer 26 over the primer coating 24. A third roller applicator 44 applies a coating 20 of sealing material (e.g., PU) to the opposite side of the sheet 34 (see also FIG. 7B), while a third oven 46 cures the sealing coating 20 at a suitable temperature (e.g., at 165° C.-170° C.). Thereafter, protective films 28, 30 are sequentially applied to the bonding layer 26 and the sealing coating 20, respectively, via one or more applicators 48. The processed sheet 34 is then formed into a roll for storage, transportation and/or further processing.

In one embodiment, the adhesive sheet 10 may be used for attaching one or more flooring or wall panels P (see FIG. 4A) to a support surface, such as a floor, a sub-floor or a wall (not shown in FIG. 4A). The adhesive layer 10 may be used as a stand-alone underlayment layer. With the protective film 28 removed, the bonding layer 26 is applied to the support surface (e.g., a sub-floor or a wall) so as to securely and fixedly attach the adhesive sheet 10 to the support surface. The protective film 30 is then removed from the adhesive sheet 10, exposing the suction holes 18b in the adhesive side 14 of the adhesive layer 16. The flooring/wall panel P is then attached to the adhesive sheet 10 via the suction holes 18b to secure same to the support surface. Sufficient pressure (as indicated by the arrow in FIG. 4A) is applied manually and/or with the use of a tool over the flooring/wall panel P, at least partially compressing the holes 18b. When the applied pressure is released, the holes 18b return to their original shapes (see FIG. 4B), creating negative pressure or partial vacuum therewithin and releasably attaching the flooring/wall panel P to the adhesive sheet 10 and hence the support surface. The negative pressure is maintained within the holes 18b by the sealing layer 20, which creates a substantially air-tight seal between the holes 18b and the bottom surface of the flooring/wall panel P. The flooring/wall panel P may be detached from the adhesive sheet 10 and hence the support surface by peeling same away from the adhesive sheet 10 and releasing the negative pressure created by the suction holes 18b. Once the flooring/wall panel P is removed, another flooring/wall panel of a different design, pattern and/or type may be installed on the adhesive layer 10. Multiple adhesive layers 10 may be installed as an underlayment layer so as to allow a user to easily and readily change the look and/or feel of his/her floor.

In one embodiment, the flooring/wall panel P may be any flooring or wall panel having a substantially non-porous bottom, such as luxury vinyl tiles (“LVT”), carpet tiles, hard wood or engineered wood panels, laminates, rubber tiles, vinyl composition tiles, decorative wall panels, wood plastic composites, rigid vinyl, sheet vinyl, multilayer flooring, stones/tiles, carpet rolls, non-polyvinyl chloride (PVC) tiles and planks, etc. In other embodiments, any item, such as other construction or decorative products, may be used in conjunction with the adhesive sheet 10 for removably attaching same to a suitable support surface.

In one embodiment, the adhesive sheet 10 is pre-laminated to a prefabricated flooring plate 52 to form a composite flooring panel 50 adapted to be releasably attached to a non-porous sub-floor or over an existing floor (see FIG. 8, in which only certain components of the adhesive sheet 10 are shown). The flooring plate 52 has a construction similar to that of a conventional flooring panel. If a conventional LVT is used for constructing the flooring panel 50, the flooring plate 52 may be provided with a top polyurethane layer 54, a wear layer 56 below the polyurethane layer 54, a pattern layer 58 below the wear layer 56, a stabilization layer 60 below the pattern layer 58, and a load bearing layer 62 below the stabilization layer 60. As will be readily apparent to a person skilled in the art, one or more layers 54, 56, 58, 60, 62 may be eliminated, or one or more additional layers may be added.

The flooring plate 52 is pre-laminated to the bonding layer 26 of the adhesive sheet 10. Accordingly, the protective film 28 is not present in the flooring panel 50. In one embodiment, the protective film 30 is present in the flooring panel 50, to safeguard the adhesive side 14 of the adhesive sheet 10.

In one embodiment, a method for making the flooring panel 50 is provided. With reference to FIG. 9, the rolled foam sheet 34 resulting from the process discussed above and illustrated in conjunction with FIG. 6 is unrolled and fed to a roller mechanism 64 together with a prefabricated flooring plate 52. The prefabricated flooring plate 52 and the adhesive sheet 10 are pressed against one another such that the flooring plate 52 is fixedly bonded to the bonding layer 26 of the adhesive sheet 10. In one embodiment, the roller mechanism 64 includes power rolls, such as nip rolls and pinch rolls, that apply high pressure to, and thereby press, two or more sheets into intimate contact for squeezing out bubbles or blisters that may cause a defective bonding.

It will be understood that the embodiments described herein are merely exemplary and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be included within the scope of the invention.
