Description

Panel suitable for installation of a waterproof floor or wall covering, method of producing a panel
The invention relates in a first aspect, to a panel of a substantially flat, rectangular shape suitable for installation of a waterproof floor or wall covering by interconnecting a plurality of said panels with each other, wherein the panel having a top surface, a bottom surface, and at least four substantially linear side edges comprising at least one pair of opposite side edges which are provided with interconnecting coupling means for interconnecting one panel within another.
The invention relates in a second aspect to a method of producing a panel according to the first aspect of the invention.
In the field of floor and wall coverings, panels are widely used based on wood materials or derivatives thereof, especially as a material for the main or central layer of the panel. An example is given in US patent 6,688,061. A major disadvantage is the hygroscopic nature of such materials, which affects the lifetime and durability of such panels especially in rooms that are regularly exposed to water spills such as a bathroom and a kitchen.
To render a panel waterproof, thermoplastic materials are used such as polyvinyl chloride for its waterproof properties. Polyvinyl chloride that is used for panels such as in patent CN 100419019, has a flexible quality which requires a perfectly smooth and even surface of the substrate on which the panel covering is applied. If such is not the case, any unevenness will be visible through the panel as it conforms with the underlying substrate surface, which is a detrimental effect from an aesthetic point of view to the user. Furthermore, the upper surface of the panel is less durable because the scratch resistance of the polyvinyl chloride is relatively low. Finally, the flexibility of the panel is cumbersome in regard of installing a covering of interconnected panels, because the assembling of the mutual interconnecting coupling means is more difficult when these can bend away from each other.
An alternative waterproof panel that is more rigid than the above flexible thermoplastic material, is a prefabricated tile from cement or concrete. The thickness required for its application is at least 16 mm, which makes the tile considerably more expensive in comparison to the thermoplastic material. Still, an evening of the underlying substrate surface is required, as well as manually gluing the tile to the substrate. A direction into which such cement- or concrete-based panels have further developed is a layered structure of a magnesium oxide main layer on which a cement top layer is fixed. An example is given in Chinese utility model CN 202644903 U. Such a panel can however only be provided with basic interconnecting coupling means such as a teeth and groove assembly (‘1st generation’ coupling), because the brittle nature of the magnesium oxide layer does not allow the milling of an intricate profiling, such as known from a groove and tongue assembly having interlocking features (‘2nd /3rd / 4th generation’). As such, glue is needed to prevent neighbouring panels from drifting away from each other. Furthermore, the magnesium oxide layer has a relatively high density of 1100 kg/m3, which is a disadvantage. Unsatisfactory in regard of the use as a floor covering is that when the panel is tread upon, the sound of footsteps is relatively loud because of the material use. In addition, the panel is rigid, which requires an evening of the underlying substrate surface.
It is an objective of the invention to meet a general need for an attractive waterproof panel, that eliminates completely or in part, one or more of the disadvantages related to the waterproof panels known from the prior art.
The above objective of the invention, is met by the provision of a panel according to the above preamble, wherein the panel has a layered structure which comprises a main layer basically composed of thermoplastic material and a top layer basically composed of a cement material on the top side of said main layer.
It is thus possible to mill intricate interconnecting coupling means as profiled structures on the side edges of the main layer, while the look and feel of a true cement tile is included on the top surface of the panel. Such intricate coupling means allow for a floating installation of a floor covering, i.e. wherein no glue is needed to prevent the drifting apart of neighbouring panels. Moreover, the panel has a considerably reduced weight, as its main layer has a low density. The low density also entails a lesser burden on the milling tools which positively affects the life time of the milling tools.
Further, the thermoplastic material provides thermal insulation and has sound dampening qualities.
Both layers are waterproof by nature, because both the thermoplastic material and cement are waterproof. Preferably in the panel according to the invention, the cement material is hydraulic cement, and contains more preferably at least 50 wt.% calcium oxide, and most preferably 60 wt.% calcium oxide. The calcium oxide in cement is typically a complex of one calcium oxide molecule with one silicate S1O2 molecule and one or more hydrates H2O molecules.
During the final stage of hardening of cement the following reactions occur: (3Ca0 Si02)2 + (x+3) H20 3 Ca02Si02xH20 + 3 Ca(OH)2 (2Ca0 Si02)2 + (x+1) H20 -> 3 Ca02-Si02-xH20 + Ca(OH)2
Typically, the cement material in the top layer according to the invention contains at least 5 wt.% silica.
Preferably, the panel according to the invention comprises two pairs of opposite side edges which are provided with interconnecting coupling means. As such, a floating floor can be installed without the need of glue at all sides of each panel.
It is further preferred in the panel according to the invention, that the interconnecting coupling means comprise a tongue and a groove wherein the tongue is provided on one side edge of one pair of opposite side edges, and the groove is provided on the other side edge of the same pair of opposite side edges. Such a design of coupling means is well-known in the art and has proven highly suitable for panels for floating floors.
In the panel according to the invention it is preferred that the interconnecting coupling means have an interlocking feature which avoids free movement of interconnected panels. Such an interlocking feature may be a projection and a respective recess provided on the respective opposite side edges by which neighbouring panels interlock with each other.
It is preferred in the panel according to the invention that the thermoplastic material comprises polyvinyl chloride or a derivative thereof. Such a material is highly suitable for its use as main component for the main layer. Another thermoplastic material that can be used for the main layer is polyethylene.
In particular, it is preferred in the panel according to the invention that the thermoplastic material has a foam structure which preferably includes an open-cell structure. The foam structure consists basically of a thermoplastic matrix in which closed and/or open cells are present. The foam structure is typically obtained by adding blowing agents to the thermoplastic melt, before it is formed and hardened into its final shape. As the foam structure has a lower density than a solid structure, the weight of the central layer is further reduced which is advantageous for the panel. The foam structure has furthermore the inherent property of better sound dampening properties than a solid structure, which provides a further attractive property to the panel. Analogously, the foam structure further improves the thermal isolation quality of the thermoplastic layer over a solid structure. The open-cell structure is preferably included as it contributes in a dominant way to the reduced density of the foam structure, and accordingly to the consequent advantageous effects above. Dependent on the chosen parameters, a density of the main layer of 300 to 900 kg/m3 can thus be achieved, of which a density in the range of 650 to 800 kg/m3 is most suitable for the panel.
In respect of the central layer of polyvinyl chloride with a foam structure the following properties are preferred: pore size: 0.01 to 0.15 mm pore volume: 20-50% density: 650 to 800 kg/m3 inherent viscosity: 0.6 to 0.84
It is preferred in the panel according to the invention, that the main layer basically composed of a thermoplastic material contains one or more filler materials chosen from the group comprising calcium carbonate, wood dust, bamboo dust, rubber, cork, jute, straw, seagrass, and paper, wherein preferably the total ratio of filler material in the main layer is 15 wt.% or lower. The filler material imparts rigidity to the main layer, and a better aesthetic appearance. In addition, the main layer may contain a pigment for imparting an attractive color to the thermoplastic material.
Preferably, in the panel according to the invention, the top layer basically composed of a cement material comprises one or more additives in particulate form, the additives being chosen from the group comprising wood, bamboo, fiberglass, straw, jute, seagrass, cellulose, granite, quartz, marble, soapstone, plastic, and mica. The additives render a decorative and/or enforcing quality to the top surface. The amount of additives is preferably at least 10 wt.% , and more preferably at least 30 wt.%. Accordingly, the top layer has a density that varies from 1000 to 1800 kg/m3, the preferred density is 1200 kg/m3.
In a particular embodiment of the panel according to the invention, the top layer is adhered to the main layer by an adhesive material. With further preference, the adhesive material is of a waterproof quality.
In a preferred embodiment of the panel according to the invention, the top layer has a thickness of 1.0 - 16 mm, and the main layer has a thickness of 2.0 - 20 mm. Accordingly, the panel has a preferred overall thickness of 3.0 - 36 mm. In a typical example of the panel the top layer and the main layer each have a thickness of 4.0 mm.
With further preference, in the panel according to the invention, a buffer layer is provided on the bottom side of the top layer. The buffer layer imparts some shock absorbing qualities to the panel in case of a heavy impact on the top surface of the panel. Furthermore, the buffer layer attributes a sound dampening effect to the panel. For that purpose, the buffer layer comprises advantageously one or more materials chosen from the group comprising cork, rubber, leather, jute, cellulosic paper, fiberglass, a plastic polymer sheet.
In a special embodiment of the panel according to the invention, a backing layer is provided on the bottom side of the main layer. Preferably the backing layer comprises one or more materials chosen from the group comprising cork, rubber, a solid foam material, cross-linked polyethylene, and cross-linked ethylene vinyl acetate. The backing layer may compensate further for any unevenness on the substrate surface on which the panels are applied. Furthermore, the backing layer attributes a sound dampening effect to the panel.
It is further preferred in the panel according to the invention, that the interconnecting coupling means are part of the main layer and/or the top layer. Dependent on the thickness of the top layer, the interconnecting coupling means are to be provided in either the top or the main layer, or in both layers, all of which variants are envisaged according to the invention.
In the panel according to the invention, it is preferred that the top layer forms a part of at least one pair of the opposite side edges, preferably of two pairs of the opposite side edges. As such, the top layer surface extends to the respective opposite side edges of which it forms a part, so that the top layers of direct neighbouring panels appear as a continuous layer.
In a particular embodiment of the panel according to the invention, the upper part of at least one side edge of at least one pair of opposite side edges is provided with a bevel. The main purpose of the bevel is to even out any possible height difference between two panels installed next to each other. When two panels installed next to each other have a slight difference in thickness, the thicker panel will have one edge projecting from the floor surface, which is a safety risk for a person walking over the floor. The projecting edge is also more prone to damage, thus reducing the durability of the floor covering. The bevel avoids that any sharp or right cornered edges stick out from the floor surface.
Furthermore, in the panel according to invention, the top layer is preferably provided with a decorative surface. Such can be achieved either by applying an additional decorative layer on the top surface of the top layer, or by colouring of or printing on the top surface.
It is also preferred that the panel according to the invention, has a top layer which has a textured top surface. The textured surface can be chosen such, that it mimics the feel of a natural stone tile, a ceramic tile, etc.
In the panel according to any of the preceding claims, the top layer is preferably coated with a protective material. As such additional protection from scratching or etching during use is provided to the panel. The protective material that is used may include oil or varnish. A special aspect of the invention relates to a waterproof floor or wall covering composed of a plurality of interconnected panels, wherein the panels are conform the first aspect of the invention. Such a covering profits from the same advantages as set out already above.
In a second aspect, the invention relates to a method of producing a panel according to the first step of the invention, comprising the steps of: a) providing a main layer of a substantially flat, rectangular shape which is basically composed of a thermoplastic material, b) providing a top layer of a substantially flat, rectangular shape which is basically composed of a cement material, c) assembling the top layer obtained in the above step on the top side of the main layer obtained in the above step, wherein an adhesive is applied at the interface between both layers, d) applying pressure on the assembly of the top layer and main layer to obtain a layered structure having a top surface, a bottom surface, and two pairs of opposite side edges; e) milling a profile structure on one pair of opposite side edges and preferably on two pairs of opposite side edges, wherein the profile structures are interconnecting coupling means.
The method according to the invention provides a new and expedient way to provide a panel according to the first aspect of the invention.
Step a) can for instance be performed by extruding a melt of said thermoplastic material into a sheet material and subsequent cooling to harden the sheet material. Subsequently the sheet material is cut to a suitable size to obtain a main layer. Other techniques for forming of a main layer out of thermoplastic material are also envisaged.
Step b) can for instance be formed by filling a suitable mold with a fluid precursor of the cement material, and subsequent application of pressure and heat to obtain a hardened top layer.
Step d) can be performed in a cold press. Optionally, heat is applied during pressing.
An alternative method of producing a panel according to the first aspect of the invention comprises the steps of: a) providing a main layer of a substantially flat, rectangular shape which is basically composed of a thermoplastic material, b) applying on the top side of the main layer obtained by the above step, a fluid layer of a precursor of cement material and allowing the precursor to harden so as to obtain a top layer basically composed of a hardened cement material, c) milling a profile structure on one pair of opposite side edges and preferably on two pairs of opposite side edges, wherein the profile structures are interconnecting coupling means.
In this method, no additional adhesive is used, because the fluid precursor of cement material has adhesive properties. The method thus provides a cost saving in producing a panel. Furthermore, it allows to create a very thin top layer of cement (of about 1 mm. thickness) on the main layer, which is not obtainable when the top layer and main layer are produced separately according to the first method described above.
In order to have a sufficient bonding strength between the cement and the main layer in the above alternative method, it is preferred that the main layer has a rough surface or a surface with texture. The rough surface can be created using a sanding machine or steel wire brush roller. The texture can be made using any suitable embossing method during or after the fabrication of the thermoplastic main layer.
In step b) it is practical that the fluid layer is applied on the top side of the main layer within a temporary boundary wall that delimits the surface over which the fluid layer is spread out.
According to a further special aspect, the invention relates to a panel according to the first aspect of the invention, that is produced using the method steps according to the second aspect of the invention.
