Description

    In our rapidly developing construction industry, the surface finishing business witnesses the challenges of increased labor, materials and time associated with installation and removal procedures due to the need for efficiency, economy and speed. Have been doing. In the floor industry where coexistence of durability and relocation is required according to constant and inconsistent demands, the waste of time, labor and materials is especially obvious. Traditional floors are traditionally installed on the underlying floor either by application of adhesive before or during installation, an interlock mechanism, or a floorboard underlay system. In order for any floor to be durable and not slip, it needs to be firmly installed on the ground floor, but the harder it is, the more the floor is installed, the floor is removed and the floor Relocation is more difficult and expensive.

    Prior to the installation of a conventional floor, much effort, time and materials are used to remove the existing floor and repair the damaged ground floor in order to make it ideal for installing the new floor. Yes. When the existing floor is removed, the adhesive remains on the surface of the base floor. The remainder of the adhesive will damage the underlying floor itself and the old floor substrate, and the old floor material after removal can no longer be reused. Once the removal is complete, additional effort, time and materials are required to firmly install the new floor. Also, wasteful disposal of old floor materials and the use of new cements, adhesives and underlay systems required for new floors can create unnecessary environmental protection costs.

    To date, the surface-covering industry, particularly the flooring industry, has experienced innovations to improve efficiency and reduce the cost of conventional installation processes. Adhesive tiles have been produced with or without release paper and have been developed to eliminate the re-application of adhesives during flooring installation. Interlocked systems have been developed to eliminate the application of adhesive by connecting adjacent tiles with a built-in mechanism. Underlay systems have been developed to allow the new floor to be fixed to the underlay system instead of the underfloor, ignoring the condition of poor quality floors. All existing developments are progressing, but retain some shortcomings and new ones have also arisen. Nothing has been found that achieves great progress with regard to tile removal within the use cycle.

    The industry's existing adhesive tiles advance, such as adhesive adhesives that attach flooring to the ground with little pressure without applying additional adhesives in the field. However, the adhesive tile can easily damage the underlying floor due to residual adhesive upon removal, causing the floor material substrate to peel or break and the floor material is no longer available. If you try to repair or keep it in good condition, the cost will increase significantly.

    Interlocking flooring systems, particularly those provided in laminates, create their own drawbacks. After installation, the connected floors are locked in place despite a seam on each tile, resulting in a single flat surface. As a result, the connection floor installed on the entire floor cannot allow the contraction or expansion of each plate or each tile. Over time, a serious problem (sever camping problem) will inevitably arise. In addition, the connected floor suffers from an increase in the level of noise pollution because a notable space is left between the ground floor and the connected floor and the sound reverberates. Upon removal, the connecting floor must be broken for the most part in order to remove the entire floor, thus creating an extra environmental protection burden and incurring material and labor costs.

    A floating floor composed of a connecting panel and a cutting material has been developed in which a single floor can be contracted and expanded as a unit. This floating floor generally requires a space between the outer periphery of the unit and the wall of the room. The interconnected panels may be glued with tongues and grooves. The interconnected panels may use self-locking joints that do not require adhesives. However, such types of floors are not ideal from an aesthetic point of view because of the gap between the floor and the walls of the room. The floating nature also limits them and is only suitable for temporary use.

    Also, underlay systems have limited benefits, whether or not pre-applied with adhesive. The underlay system is itself a complex assembly, although pretreatment of the underfloor is eliminated because it acts as a mediator between the new floor finish and the underfloor. Manufacturing is costly and installation is cumbersome and complicated. The extra effort of preparing structural support element fasteners, stables and other structures to hold the floor in place results in substantial additional costs in the installation process. It will be. Most underlay systems require special tools for installation.

    Aside from the limitations described above, all items on the market are subject to extra environmental protection burdens during the installation and removal processes (for example, waste of materials resulting in by-products, cumbersome cleaning processes and removal). Resulting in inability to recycle the used floor after it has been removed.

    Therefore, a flooring that can be easily installed and removed without adding time, labor, cost, tools and energy, and has durability and slip resistance (property that does not slip even when walking) is required. Become. Also, the removal performance of 100% clean so that it can be rearranged and reused even after repeated installation and removal (no damage to the underlying floor, no adhesive remains, no removal) Flooring that has all of the beneficial features and the initial adhesion is required. Furthermore, it would be advantageous and desirable to provide an effective and clean floor installation and relocation method that eliminates the burden of removing residual adhesive and waste of material.

    Similarly, it provides enhanced moisture release as an additional feature in flooring to minimize the accumulation of dust and dirt in and under tile seams and to release increased pressure due to water vapor in the underlying floor. It is desirable to do.

    In addition, there is no “sticky” or “sticky” when touched, no adhesive remains, and it is suitable for both permanent and temporary tile installation. It would be desirable to provide a floor bonding method that is resistant to slippage.

Finally, do-it-yourself installation, removal, and re-installation ("Paste-Peel-Paste") can be done easily, and even untrained people can move flooring from one place to another as part of the bottom It is desirable to provide a device that can be moved in its original form.

[Summary of the Invention]

    The present invention relates to a removable floor finish. The floor finish is a structural improvement of a floor tile, sheet or plate. Examples of the floor finish include floor tiles, sheets, plates, and cutting materials having various sizes, shapes, and surfaces. The floor finish may be polyvinyl chloride, rubber, linoleum, polymer resin, reinforced resin, vinyl composite material, other elastic materials, carpet, stone, ceramic, metal, glass, etc. And fabrics, wood, composites of the desired combination, thin sheets of the desired combination, laminates of the desired combination, and everything that is later referred to as “floor finish” The one formed by

    More particularly, the present invention provides a floor covering having a dual backing layer comprising a foam layer and a curable adhesive layer. This dual backing layer allows the floor finish to be installed directly on the underlying floor surface with little additional pressure and no additional adhesive or underlay system. Significantly, the floor finish reinforced with this dual backing layer can be easily removed from the underlying floor without leaving or damaging the underlying floor or floor substrate. In addition, the floor finish can be re-installed without compromising the original adhesive effect. In this way, a floor finish is provided which is sticky, can be removed and rearranged, and is referred to as "stick-peel-stick".

    The present invention allows such an improvement to the structure by the addition of at least two innovative backing layers, with no moisture passage and with a moisture passage. In one embodiment, the backing layer without a moisture permeable channel has an upper layer that is adhered to the back surface of the floor finish with an adhesive. The adhesive is a soft and elastic material, and is usually formed on the foam layer side with a thickness of about 0.5 mm to 3.0 mm. Moreover, this backing layer without a moisture-permeable path has a lower layer made of a curable adhesive on which a curing process or a crosslinking process is performed. Soft, elastic, cushioning, or foam-like materials are chemically expanded polyvinyl chloride plastisol / organosol, acrylic, polyurethane foam, polyvinyl chloride plastisol or floss like acrylic. It may be selected from the group comprising foams, melt-processed foams such as polyvinyl chloride, polyethylene, ethylene vinyl acetate, metallocene polyolefins, elastomeric polyolefin copolymers. Of course, other unformed materials may be used with the proper effect.

    The curable adhesive should have sufficient tack and slip resistance so that the floor finish can be removed from the underlying floor and relaid elsewhere. In one embodiment, rubber adhesives, PVC adhesives, acrylic adhesives, electron beam curing acrylic adhesives, vinyl acetate adhesives, urethane adhesives, and combinations thereof are accompanied by appropriate results. Have been used in the present invention. The curable adhesive is supplied onto the foam layer after the curing process is completed by a conventional coating device such as a reverse roll coater, forward rotating roll coater, doctor blade, air knife or other similar device. May be. The thickness of the layer is usually 0.1 mm, but may be thinner or thicker depending on (the material of) the curable adhesive.

    When a dual backing consisting of a foam layer and a curable adhesive is applied to a floor finish of any material composition, the “stick peel stick” function is achieved. To create a flooring system that can be freely laid. Additional features and advantages of the present invention include the foam layer providing flat adhesion to allow the floor finish to be in uniform contact with the underlying floor. The foam layer also makes the floor more comfortable, warmer on walking, more shock-absorbing and making an acoustic sound. The curable adhesive is more remarkable after the floor is removed, so that all the original adhesive strength remains even after the removed floor is cleaned with water and wet cloth. Even if it is touched after removal and before installation, the yarn does not pull (non-string) and does not stick (non-sticky).

    In another embodiment, a backing structure with a moisture permeable passage is provided. The backing structure is structured except that a soft, elastic or cushioning or foam-like material is made to form a plurality of grooves so as to overlap the curable adhesive layer. The configuration is similar to the above-described backing structure (backing structure without a moisture permeable path). The plurality of grooves allow moisture to be released from under the floor finish. They also strengthen the surface tension that causes the floor finish to adhere to the underlying floor. Further, the floor finishing material can be removed only with a tensile force in a direction parallel to the groove direction, and cannot be removed with a tensile force in a lateral direction or an oblique direction.

    According to this structure, the floor finish formed in accordance with the present invention can be installed in a loose-lay. The floor finish does not require an adhesive, release paper, an underlay system or an interlock mechanism. The floor finish can be removed manually and cleanly (no adhesive remains on the floor side), and it can be moved and kept in place while maintaining the initial adhesive strength and features. Can be rearranged. The groove structure of the cushion layer creates a tile that is 100% recyclable, has slip resistance and can be loose-laid, and is intended to be removed from the underlying floor in horizontal and diagonal directions. Resists the pulling force.

These and other features and advantages of the present invention will be more fully disclosed and will become more apparent in the following detailed description (description of preferred embodiments of the invention). The detailed description should be considered in conjunction with the accompanying drawings, in which like parts are labeled with like numerals.

    With reference to FIGS. 1-5, a floor section member 10 formed in accordance with the present invention may include vinyl tiles and other floor finishes. Although not limited, polyvinyl chloride, rubber, linoleum, polymer resin, reinforced resin, vinyl composite materials, other elastic materials, carpets, stones, ceramics, metals, Glass, cloth, wood, their composites in a desired combination, their thin plates in a desired combination, their laminates in a desired combination, and all the later mentioned as flooring materials 10 Things.

    The 1st Embodiment of this invention is shown by FIG.1 and FIG.2, and consists of the cutting material 10 for floors without a moisture-permeable path. The floor cutting material 10 is a floor surface finishing material that is sticky and is installed in a loose-lay. The upper wear surface layer 11 and the upper wear surface layer 11 are formed into a cushion material layer 13. It is a multilayer having an internal adhesive layer 12 to be fixed. Another internal adhesive layer 14 is disposed by back coating with a curable adhesive. The upper wear surface layer 11 may be formed of polyvinyl chloride (PVC) or other suitable surface material. The present invention is formed from various materials including polymer resins, rubber, linoleum, reinforced resins, in-aid floors, elastic floors, carpets, stones, ceramics, wood, parquets, composite materials, veneers, laminates and combinations thereof. Applied to other surface layers. The upper wear surface layer 11 can be of various widths, thicknesses, densities, edge shape designs, colors, patterns, chemical properties, and compositions, depending on the particular material that forms it.

    The upper wear surface layer 11 is bonded to the thin cushioning backing of the cushion material layer 13 by the internal adhesive layer 12. The upper wear surface layer 11 is defined by an upper surface 11a (surface that forms the uppermost surface of the floor cutting material 10) and a lower surface 11b (surface that forms the lowermost surface of the floor cutting material 10). The inner adhesive layer 12 adheres the lower surface 11 b to the uppermost surface 13 a of the cushion material layer 13. The cushion material layer 13 is defined by the upper surface 13a and the lower surface 13b. The lower surface 13b is adhered to a back coating of a curable adhesive similar to the internal adhesive layer. The inner adhesive layer 14 is defined by the upper surface 14a and the lower surface 14b, and forms the lowermost layer of the floor cutting material 10.

    The upper wear surface layer 11 may be composed of any kind of flooring. Although not limited, polyvinyl chloride, rubber, linoleum, polymer resin, reinforced resin, vinyl composite materials, other elastic materials, carpets, stones, ceramics, metals, They are glass, cloth, wood, a composite of them in a desired combination, a thin plate of them in a desired combination, and a laminate of them in a desired combination. The cushion material layer 13 is made of various soft and elastic materials. Foam polymers such as, but not limited to, foamable polymers and, in particular, chemically expanded polyvinyl chloride plastisol / organosol, acrylic, sponge rubber, polyurethane foam, polyvinyl chloride plastisol and acrylic It is a melt-processed foam such as a polyvinyl chloride, polyethylene, ethylene vinyl acetate, metallocene polyolefin, and elastomeric polyolefin copolymer. In addition, foaming and non-foaming, soft or elastic or cushioning materials may also be used. The thickness of the cushion material layer 13 is usually about 0.5 mm to 3.0 mm. The cushion material layer 13 is configured so that the floor cutting material 10 and the ground floor are in uniform contact. This greatly increases the degree of adhesion of the floor cutting material 10 to the ground floor and enhances the sound absorption of the floor cutting material 10. It also makes the floor more comfortable for walking and enhances shock absorption.

The inner adhesive layer 14 is often formed or applied as a curable adhesive coating that adheres to the underlying floor with very little pressure, but this adhesive layer 14 is the original “tack” that remains almost unchanged. The floor cutting material 10 is allowed to be lifted, removed or rearranged so that there is no residual adhesive or peeling of the underlying floor. The curable adhesive constituting the internal adhesive layer 14 is a rubber adhesive, PVC adhesive, acrylic adhesive, electron beam curable acrylic adhesive, vinyl acetate adhesive, urethane adhesive, or a combination thereof. Any adhesive that is cured, including: In order to hold the floor cutting material 10 in place during use, the lower surface 14b of the internal adhesive layer 14 must have sufficient tackiness. The inner adhesive layer 14 must be releasable so that the floor cut 10 can be removed and repositioned. One adhesive discovered to give adequate results has a viscosity of 3000-5000 cps at 25 ° C., a density of 1.0-1.1 g / cm ³ , 10 M /% with 80% active ingredient It consists of a modified acrylate with a cure rate faster than min / Lamp (80 Wcm ⁻¹ ). Examples of the specific adhesive coating method include a reverse roll coater, a forward rotation roll coater, a doctor blade, an air knife, and other similar devices.

The lower surface 13b is adhered to a back coating of a curable adhesive similar to the internal adhesive layer. The standard for the back coating (ie, the lower adhesive layer that is applied to the lower surface 13b of the foam layer and contacts the underlying floor) is the following curable adhesive. That is,
(1) A curable adhesive that undergoes a curing and crosslinking process,
(2) A curable adhesive having an initial adhesive force sufficient to bind or hold particles on the adhesive surface and holding a backing layer in contact with the underlying floor,
(3) A curable adhesive that is non-stringing and relatively resistant to intrusion and compression of particles,
(4) A curable adhesive which has an average thickness of about 0.03 mm to 0.05 mm and becomes thinner than 0.03 mm or thicker than 0.05 mm by use.
The cushion material layer 13 has a thickness of about 0.5 mm to 3.0 mm, and the thickness may vary depending on use. The thickness of the curable adhesive is generally determined in the range of 0.01 mm to 0.3 mm, but is preferably thinner than 0.1 mm.

    With reference to FIGS. 3 and 4, another embodiment of the present invention comprises a floor cutting material 20, such as a floor tile, having a moisture permeable layer 24. The floor cutting material 20 is seen and consists of multiple layers having an upper wear surface layer 21 as the uppermost layer, which is a contact surface and a wear surface. An inner adhesive layer 22 is bonded to the lower surface of the upper wear surface layer 21. Below the upper wear surface layer 21, a cushion material layer 23 and a moisture permeable path layer 24, which is the lowermost layer, are arranged. The moisture permeable path layer 24 has a plurality of lands arranged so as to separate a plurality of grooves 27 arranged at regular intervals so as to cross the bottom surface of the floor cutting member 20 (between the grooves). 26. The moisture permeable layer 24 is preferably an adhesive layer that is cured and functions as an adhesive that holds the floor cutting 20 in place and allows the floor cutting 20 to be removed and repositioned. Formed. The moisture permeable path layer 24 is preferably pressure-sensitively bonded, such as a rubber adhesive, an acrylic adhesive, an electron beam curable acrylic adhesive, a vinyl acetate adhesive, a urethane adhesive, or the like. It may be formed of combinations or other commonly used adhesives that are cured. The moisture permeable layer 24 is usually pressed or embossed so as to have alternating lands 26 and grooves 27.

    Although the upper wear surface layer 21 is formed of polyvinyl chloride (PVC), the present invention can be applied to wear surface layers of various materials. Although not limited, polyvinyl chloride, rubber, linoleum, polymer resin, reinforced resin, vinyl composite materials, other elastic materials, carpets, stones, ceramics, metals, The present invention can be applied to glass, cloth, wood, composites thereof in a desired combination, thin plates in a desired combination, and laminates in a desired combination. The upper wear surface layer 21 may be formed with various widths, thicknesses, densities, edge shape designs, colors, chemical properties, and compositions depending on the material forming the wear surface layer. I don't know.

    The upper wear surface layer 21 is often attached to the cushion material layer 23 by the internal adhesive layer 22. The upper wear surface layer 21 is defined by an upper surface 21a (the uppermost contact and wear surface of the floor cutting member 20) and a lower surface 21b. The internal adhesive layer 22 is bonded to the lower surface 21b and the surface 23a (the uppermost surface of the cushion material layer 23). In many cases, the cushion material layer 23 is made of ethylene vinyl acetate foam, polyethylene foam, sponge rubber, polyvinyl foam, or other materials that are soft and have cushioning properties and elasticity. The thickness of the cushioning material layer 23 is in the range of 0.5 mm to 3.0 mm, and promotes uniform contact of the floor cutting material 20 with the base floor, thereby leading to the base floor of the floor cutting material 20. Promotes flat adhesion.

    The cushion material layer 23 is defined by an upper surface 23a and a lower surface 23b. The moisture permeable layer 24 may be applied or adhered to the lower surface 23 a of the cushion material layer 23 and may additionally have a curable adhesive layer 25. The moisture permeable path layer 24, which is the lowermost layer of the floor cutting material 20, has a plurality of protruding lands 26 that alternate with adjacent grooves 27. As shown in FIG. 3, which is a bottom view of the floor cutting material 20, the land 26 and the groove 27 often extend in parallel with each other over the length and width of the floor cutting material 20. . Of course, other directions and arrangements of the grooves and lands have the same appropriate effects.

    The moisture permeable layer 24 sticks to the base floor. The surface tension for bonding the floor cutting material 20 to the underlying floor is reinforced. Such a molding surface resists horizontal or diagonal tensile forces and resists movement on the underlying floor. The floor cutting material 20 is stretched in parallel with a vertical structural backing due to the presence of air channels on the grids (moisture permeable channels). Removed from. The floor cutting material 20 maintains its original shape and cannot be easily moved by a tensile force in a horizontal direction or an oblique direction. The moisture permeable path layer 24 retains the adhesion of the floor cutting material to the ground floor and the aesthetic value of the floor cutting material 20, while maintaining the contact point with the ground floor (the point of contact with the sub-floor). Allow evaporation of moisture. Further, this arrangement does not accumulate unnecessary particles on the floor cutting material 20 or contaminate the cutting material 20, and the contact point of the moisture permeable path layer 24 with the ground floor is not damaged.

    Referring to FIG. 5, a flowchart of an exemplary manufacturing process for a floor tile 20 in the form of a vinyl tile formed in accordance with the present invention is provided. The manufacturing process is a general conventional method for manufacturing a tile by any one of extrusion molding, calendering, and heat-pressure welding laminating. As shown in Chart 41, the process begins with a surface layer that is a printed polyvinyl chloride film (PVC film). Next, a polyvinyl chloride film is extruded into tiles by heat lamination and the process shown in FIG. In the process shown in the chart 42, calcium carbonate is mixed with the polyvinyl chloride mixture, and extrusion is performed through the Bumberly process and the crusher. Next, the tile surface is embossed and cooled and annealed. Then, an adhesive is applied to the back surface of the tile.

    A foam layer is applied to the tiles described above in accordance with the present invention. Chart 43 shows the process of forming the foam layer. In Chart 43, a mixture of foamable materials is subjected to Bumbery or extrusion and cut to fit the already manufactured tile.

    As shown in FIG. 41, when the foam layer is attached to the back surface of the tile, the back surface is smoothed and an optional UV coating is performed. Next, the tile is dried by ultraviolet irradiation, a curable adhesive is applied to the foam layer, and drying by ultraviolet irradiation is performed. The manufacturing process is complete and the tiles are ready for packing.

    The main use of the present invention would be for a standard floor. However, it applies to similar environments to derive the characteristics of the preferred embodiment. Floor finishes are used to cover the floor surface.
