Panel suitable for constructing a waterproof floor or wall covering, method for producing a panel
The present invention relates to a panel suitable for constructing a waterproof floor or wall covering, having a substantially planar top surface, a substantially planar· bottom surface, and at least four substantially linear side edges, wherein the panel has a laminate structure which comprises a core layer basically composed of a composite material comprising a mixture of mineral material and thermoplastic material, comprising at least one pair of opposite side edges which are provided with interconnecting coupling means for interconnecting one panel within another, and a top layer fixed to the core layer.
Such panels are widely known and useful for constructing a waterproof floor or wall covering, and are for instance apparent from the patent publication US 7763345. The thermoplastic nature of the panels provides an appropriate barrier to water spillage or damp conditions, and is therefore advantageous. The need for moisture-proof flooring and wall panels is obvious, as moisture may either damage the panels themselves, or could penetrate through the joint, and cause substantial damage to the structural integrity of the substrate, it may lead to growth of mould and thus cause harm to human health.
Locking systems known in the field that claim to offer increased moisture resistance, do so by preventing damage to the panels, by waterproofing the core through the application of a layer of moisture repelling material, or by improved water tightness by sealing off the edges of the locking mechanism by mechanical or chemical means under pressure of installation.
Coating the joint surfaces with a moisture-sealing or moisture repelling material such as silicone or paraffin to prevent water damage is described in international patent applications WO 94/26999, EP 0903451 and EP 1493879. The use of a moisture resistant or repelling layer on the edges of the locking system does however not block water ingress, it only protects the core layer of the product envisioned from being affected by water. It thus fails to meet the second requirement of moisture resistance, which is to block moisture from the surface from penetrating through to the underlying substrate. The use of thermoplastics or other moisture resistant core materials is for this reason also insufficient, as it does not prevent water ingress.
US application US 20130269279 describes the application of a water resistant material to at least pail of the lock system, which is used to form a so called barrier under stress of installation. EP 1512808 similarly describes the application of a moisture resistant varnish, paint or resilient flexible material on the edges of the lock system, that are forced together during installation to form a physical moisture banier. US Patent 8028486 and international patent application W02003012224 describe the use of an elastic sealing material that is compressed when neighbouring flooring panels are joined together.
The downsides of these mechanical sealing methods as described above are apparent, as each requires an added locking surface comprised of material different from the core material, which entails considerable added cost to production and consumer. It requires direct contact of the sealant with the connecting surfaces, which greatly impacts the ease of installation.
Application WO 2004 0168 describes the application of an adhesive composition applied to at least a portion of the edges of an locking mechanism, however, the manual application of glue to ensure water resistance is cumbersome as it requires the adhesive to be applied at the time of installation. The 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 floorboard comprising a substrate of HDF material at a side edge, the use of HDF material combined with a superabsorbent material necessitating the use of an impregnation agent to reduce swelling and absorption of water by the HDF. Both swelling and water absorption are reported to still be significant; therefore the use of a superabsorbent sealing agent using the envisioned core material is not optimal nor practical. Nor the water tightness of the installed flooring installation, nor the speed of water penetration through to the substrate, are touched upon or envisioned.
The objective of the present invention is to provide a panel which offers an appropriate solution to one or more of the above requirements and/or general needs, and/or to take away the disadvantages of the cited prior art, and/or to provide a useful alternative.
This objective is achieved according to a first aspect of the invention by the provision of a panel suitable for constructing a waterproof floor or wall covering, having a substantially planar top surface, a substantially planar bottom surface, and at least four substantially linear side edges, wherein the panel has a laminate structure which comprises a core layer basically composed of a composite material comprising a mixture of mineral material and a binder, comprising at least one pair of opposite side edges which are provided with interconnecting coupling means for interconnecting one panel within another, a top layer fixed to the core layer, wherein at least part of a surface of at least one of the opposing side edges and/or coupling means thereof comprises at least one pre-applied sealer, which sealer comprises a hydrophilic material. The binder may for instance be a thermoplastic material.
One advantage of the panel according to the present invention is that it seals off the joint completely and does not to allow moisture to penetrate through to the substrate.
The present invention reduces swelling and water damage in an improved way by using a waterproof mineral-based core that does not necessitate the use of an impregnation agent before the application of a sealer. The sealer also succeeds in blocking out ingress of water spills to the substrate.
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. Evidently, these values are values when maximum saturation has taken place. The actual expansion until that condition is satisfied depends on the amount of liquid absorbed by the sealer. However, the percentages as mentioned above have appeared to be enough to fill any gaps between adjacent panels, once properly coupled via their interconnecting coupling means.
The above mentioned values can for instance be obtained when the hydrophilic material comprises a super absorbing polymer or super absorbing polymer compound such as sodium polyacrylate or hydrophilic polyurethane. Sodium polyacrylate has the ability to absorb as much as 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. While sodium neutralized polyacrylic acids are the most common form used in industry, there are also other salts available including potassium, lithium and ammonium, which may also be applied according to the present invention. Hydrophilic polyurethane may absorb up to 15 times its weight in fluids.
There are several methods for manufacturing a panel according to the present invention. In particular, the hydrophyllic material may be applied in various manners. For instance it is applied as a liquid, or as particles embedded in the sealing material.
Appliance as a liquid has the benefit that it can be applied as a second layer on top of a previously applied second sealing material.
Appliance as particles in the sealing material has the benefit of reduced cost of production, as the particles can be embedded in a single layer of sealing material.
The composite base layer of the panel according to the present invention may comprise a mineral compound such as MgCh, MgSCU, or CaCCh. with a weight percentage of more than 1%, preferably more than 10%, most preferred more than 20%.
Preferably, in the panel according to the invention, the waterproof core layer is made from a mineral material combined with a binder. For the material of the waterproof core a wide range of materials may be considered, provided these are suitable for the intended use, which requires they contain less than 30 wt.% of cellulosic and/or plant material. As a mineral material, magnesium oxide and/or magnesium hydroxide, combined with a suitable binder can be used. A suitable binder is magnesium chloride, magnesium sulphate, ferric sulphate, potassium salt, a plastic material, a resin, or an adhesive, or a combination of these compounds. As an alternative mineral material, Portland cement based material may be considered.
As a thermoplastic material, PVC or other vinyl compounds are typically suitable, as well as PE, PU or PP.
In a preferred embodiment, the composite base layer of claim 1 contains as a binder a mineral compound, or a thermoplastic polymer. This provides the advantage that the finished product core itself is fully waterproof and does not require additional sealing of the core material.
Alternatively or additionally, the panel according to the invention may comprise a wood dust content. Such content has proven to add positively to weight and cost properties of the panel, while it also adds structural strength. Experiments have shown that a wood dust content of less than 12% by weight of the composite base layer prohibits the growth of fungus.
The top layer also may preferably comprise at least one layer of lignocellulosic fibres. Here, the fibres when impregnated with a thermosetting resin, have the advantage that they offer superior scratch resistance compared to traditional thermoplastic flooring. The combination of both a base layer and a top layer comprising lignocellulosic fibres has the extra benefit of added rigidity of about 75% .
Such layer of lignocellulosic fibres may be laminated to the top surface of the base layer in a laminate hot press. This approved method allows an optimal bonding of the different layers in the structure as well as a superior resistance to micro scratches and is the preferred embodiment of the invention. However, the top layer may also be a layer of a different material such as thermoplastic and glued to the top surface of the core through a cold pressing process. Through this process, multiple embodiments of the product become possible that make it suitable for a wide range of applications. It is a possibility to include in the core a binder of a thermoplastic nature. In this case, a thermoplastic top layer can also be laminated to the top surface of the base layer in a multi daylight press. This method may be preferred in case of required high acoustical performance of the product. Optionally, the panel according to the present invention may a comprise a back layer for improved acoustical performance.
