Description

Panel suitable for constructing a waterproof floor or wall covering and method for manufacturing a panel
Technical Field
the present invention relates to a panel (panel) suitable for constructing a waterproof floor or wall covering, said panel having a substantially flat top surface, a substantially flat bottom surface and at least four substantially linear side edges, wherein said panel has a laminate structure comprising a core layer consisting essentially of a composite material comprising a mixture of a mineral material and a thermoplastic material, and a top layer secured to the core layer, said core layer comprising at least one pair of opposing side edges provided with interconnecting coupling means for interconnecting one panel within another panel.
Background
Such panels are well known and are useful in the construction of waterproof floor or wall coverings and are for example well known from the patent publication US 7763345. The thermoplastic nature of the panel provides adequate protection against water leakage or wet conditions and is therefore advantageous. There is a clear need for moisture resistant floor and wall panels as moisture can damage the panels themselves or can penetrate the joints and cause significant damage to the structural integrity of the substrate, which can lead to mold growth and thus health hazards.
Locking systems known in the art purport to provide improved moisture protection of floor and wall panels by preventing damage to the panels, waterproofing the core by applying a layer of moisture repellant material, or improving water tightness by mechanically or chemically sealing the edges of the locking mechanism under installation pressure.
International patent applications WO94/26999, EP0903451 and EP1493879 describe coating the joint surfaces with a material that seals or repels moisture, for example silicon or paraffin, to prevent moisture damage. However, the use of a moisture-proof or moisture-removing layer on the edges of the locking system does not prevent the entry of water, but only protects the core layer of the envisaged product from water. Therefore, it fails to satisfy the second moisture-proof condition that is to block moisture from penetrating from the surface to the underlying substrate. Therefore, the use of thermoplastic or other moisture barrier core materials alone is also insufficient, as this does not prevent the ingress of water.
US application US20130269279 describes the application of a waterproofing material to at least a part of a locking system for forming a so-called barrier under installation pressure. EP1512808 similarly describes the addition of a moisture resistant varnish, paint or resilient flexible material on the edges of the locking system which are forced together during installation to form a physical moisture barrier. Us patent 8028486 and international patent application WO2003012224 describe the use of resilient sealing materials that are compressed when the panels of adjacent floor panels are joined together.
The disadvantages of these mechanical sealing methods as described above are evident, since each method requires the addition of a locking surface comprising a material different from the core material, which entails a considerable increased cost for the producer and the consumer. This requires direct contact of the sealant with the attachment surface-greatly affecting the ease of installation.
Application WO20040168 describes applying an adhesive composition to at least a portion of the edge of the locking mechanism, however, the manual application of glue to ensure waterproofness is cumbersome, since it requires the application of adhesive at the time of installation. Pre-application of glue requires direct contact of the adhesive with the opposing edge in order to be effective.
applications WO2016182896a1 and EP3294969a1 each disclose a floor comprising a matrix of HDF material at the side edges, which HDF material, when used in combination with a superabsorbent material, must use a soaking agent to reduce the swelling and water absorption of the HDF. The swelling and water uptake is said to remain evident; superabsorbent sealants using contemplated core materials are therefore neither optimal nor practical. Neither the watertightness of the installed floor unit nor the speed at which water penetrates the matrix is involved or considered.
Disclosure of Invention
It is an object of the present invention to provide a panel which provides a suitable solution to one or more of the above-mentioned needs and/or overall needs, and/or which obviates the drawbacks of the cited prior art, and/or which provides an advantageous alternative.
This object is achieved according to a first aspect of the invention by providing a panel suitable for constructing a water-resistant floor or wall covering, the plate member having a generally planar top surface, a generally planar bottom surface and at least four generally linear side edges, wherein the panel has a laminate structure comprising a core layer and a top layer secured to the core layer, the core layer consisting essentially of a composite material comprising a mixture of a mineral material and a binder, the core layer comprising at least one pair of opposed side edges, said at least one pair of opposite side edges being provided with interconnecting coupling means for interconnecting one panel within the other, wherein at least a portion of a surface of at least one of the opposing side edges and/or its coupling means comprises at least one pre-applied sealant comprising a hydrophilic material. The binder may be, for example, a thermoplastic material.
One advantage of the panel according to the invention is that it completely seals the joint and does not allow moisture to penetrate to the substrate.
Detailed Description
The present invention reduces swelling and water damage in an improved manner by using a water-repellent mineral-based core that does not require the use of a soaking agent prior to application of the sealant. The sealant also successfully prevented water leakage into the matrix.
The hydrophilic material is configured to expand by at least 10%, preferably more than 20%, most preferably more than 50%, when in contact with moisture. Obviously, these values are the values when the maximum saturation is reached. The actual expansion before this condition is met depends on the amount of liquid absorbed by the sealant. However, once properly coupled by the interconnecting coupling means of adjacent panels, the percentages described above appear to be sufficient to fill any gaps between adjacent panels.
This value can for example be obtained when the hydrophilic material comprises a superabsorbent polymer or a superabsorbent polymer compound, such as sodium polyacrylate or a hydrophilic polyurethane. Sodium polyacrylate has the ability to absorb water 100 to 1000 times its mass. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxyl groups in the backbone. While sodium neutralized polyacrylic acid is the most common material used in the industry, other salts, including potassium, lithium and ammonium salts, may also be used in accordance with the present invention. Hydrophilic polyurethanes can absorb up to 15 times their weight in liquid.
There are various methods for manufacturing the panel according to the invention. In particular, the hydrophilic material can be coated in various ways. For example, the coating is carried out in a liquid form or in the form of particles embedded in a sealing material.
The application in liquid form has the advantage that it can be applied as a second layer on top of the previously applied second sealing material.
coating in the form of particles in the sealing material has the advantage of reduced production costs, since the particles can be embedded in a single layer of sealing material.
The composite base layer of the panel according to the invention may comprise a mineral compound, such as MgCl2, MgSO4 or CaCO3 in a percentage by weight of more than 1%, preferably more than 10%, most preferably more than 20%.
Preferably, in the panel according to the present invention, the waterproof core layer is made of a mineral material in combination with a binder. A wide variety of materials may be considered as materials for the waterproof core, as long as they are suitable for the intended use, which requires that they contain less than 30% by weight of cellulosic and/or vegetable material. Magnesium oxide and/or magnesium hydroxide in combination with a suitable binder may be used as mineral material. Suitable binders are magnesium chloride, magnesium sulfate, iron sulfate, potassium salts, plastic materials, resins or binders or combinations of these compounds. It is possible to consider the use of portland cement-based materials as an alternative to mineral materials.
PVC or other vinyl compounds and PE, PU or PP are generally suitable as thermoplastic materials.
In a preferred embodiment, the composite substrate according to claim 1 comprises a mineral compound or a thermoplastic polymer as binder. This provides the advantage that the finished core is itself completely waterproof and does not require additional sealing of the core material.
Alternatively or additionally, the panel according to the invention may comprise wood chips content. Such inclusion has proven beneficial in increasing the weight and cost characteristics of the panel, while also increasing structural strength. Experiments have shown that wood chip content of less than 12% by weight of the composite substrate prevents fungal growth.
The top layer may also preferably comprise at least one layer of lignocellulosic fibres. Here, the fibers have an advantage in that they provide superior scratch resistance compared to conventional thermoplastic floorings when impregnated with a thermosetting resin. The combination of both the base ply and the top ply comprising lignocellulosic fibres has the additional benefit of increasing the stiffness by about 75%.
Such a layer of lignocellulosic fibres may be laminated to the top surface of the base layer in a thermal laminator. This proven method allows for optimal bonding of the different layers together in the structure, excellent resistance to slight scratches and is a preferred embodiment of the invention. However, the top layer may also be a layer of a different material, such as a thermoplastic, and bonded to the top surface of the core by a cold pressing process. By this process, the product can be obtained in a number of embodiments, which makes it suitable for many applications. A thermoplastic binder can be included in the core. In this case, the thermoplastic top layer may also be laminated to the top surface of the base layer in a multi-layer press (multi-daylight press). This method is preferably used in situations where the product has the desired good acoustic properties. Optionally, the plate according to the invention may comprise a bottom layer in order to improve the acoustic performance.
