Definitions
- the present invention relates to a rigid panel for construction with central foamed layer and resin coating.
- the invention is intended for use in the building industry and particularly in the sector of semi-finished components for construction such as, by way of non- limiting example, insulating panels and constructive elements of walls and subfloors. More in detail, a lightweight self-supporting panel of the sandwich type is proposed, which is made up of a core in a foamed insulating material such as polystyrene, both expanded and extruded and otherwise called by the acronym XPS (extruded polystyrene insulation), or expanded only and otherwise called by the acronym EPS, or such as polyurethane otherwise called by the acronym PIR or PUR, with a particular outer coating layer which makes it rigid, resistant to bending and damp, and also provided with a good adhesion to glues and/or cement mortars.
- XPS expanded polystyrene insulation
- EPS expanded only and otherwise called by the acronym EPS
- PIR or PUR polyurethane otherwise called by the acronym
- the proposed panel is usable as constructive element for interior architecture, instead of conventional bricks made of clay or cement, also acting as a support for the gluing of tiles in damp environments as in the case of bathrooms, saunas, laundry rooms or kitchens.
- it is suitable for making walls, floors and/or spaces for the insertion of bathtubs and showers, or seats or niches integrated in the walls of modem bathrooms coated with ceramic tiles.
- non-conductive or insulating panels are widely known and widespread, which are made up of an inexpensive rigid material, having an extremely low weight but a highly non-conductive performance such as expanded polystyrene or extruded polystyrene, otherwise called by the acronyms EPS and XPS.
- EPS or XPS panels are single-layer panels-and their opposite main faces are smooth and parallel one another, having constant thickness; some solutions provide the outer main faces coated with a protective film in different materials, such as for example a paper sheet or a plastic plate or a non-woven fabric.
- insulating panels made up of a rigid foam obtained with other foam materials are known and widespread, which sometimes offer a good insulating performance, but are sometimes disadvantageous due to some mechanical characteristics, of resistance to bending or damp, of long-term durability and/or for production reasons.
- expanded polyurethane offers a good insulation capacity, but it has to be adequately protected, since it is characterized by a resistance to water and vapor which can be inadequate in particular applications.
- EPS or XPS panels are mostly required not only for the advantageous characteristics of resistance and versatility, but also because in the production phase they require a considerably lower quantity of primary energy; moreover, they are easily recyclable.
- Insulating panels made of EPS or XPS are widely used at the extrados of the vertical walls and also in the interspaces between wall partitions, in floor slabs and in roof pitches; particularly, XPS panels have a structure with perfectly closed and uniform cells and are more suitable where a high thermo-insulating capacity is required also in combination with compressive strength and/or water repellency, such as for example in the case of underground rooms or inverted roofs.
- said expanded EPS, or expanded- extruded XPS polystyrene is extremely advantageous for various aspects: for performance, productive, economical, and recyclability aspects; however, it has some problems when it is used as material for building panels for construction, according to the specific aims of the present invention.
- a first problem concerns its poor resistance when used with structural functions, such as a constructive element of walls, partitions, infill walls or as support for ceramic coatings, plasters, or any surface finishing for environments.
- a conventional EPS or XPS panel has a low resistance to bending and to damp and has a surface which is not suitable for the grab of glues or cement mortars commonly used.
- said EPS or XPS panels are covered with the cited protective films, such as a paper sheet or a plastic plate or a non-woven fabric.
- Additional layers are also known, which are fire resistant, non-flammable or anyway able to retard combustion; by way of example only, in the vertical walls of buildings such protective layers are made of plasterboard, fiber cement, magnesium oxide, wood - cement or made with a layer in rock or glass wool so as to completely coat the panel or at least its side edges, since they are the preferred combustion priming zone.
- Protective sheets made of metal or cement are also known, which are applied on the outer surface of the panel.
- manufactures made with such added layers have a high thickness, a remarkable specific weight, difficulties of working and cutting, hygroscopicity, poor dimensional stability, low tensile strength, and high costs.
- expanded polystyrene comprising graphite particles is known, which is suitable for offering a reduced thermal conductivity, limiting the thickness provided for insulation, and is also suitable for absorbing and reflecting infrared rays, such as the material marketed under the name Neopor® of the German company Basf SE, Ludwigshafen - www.basf.com, having a thermal conductivity of 0.031 W/mK and a density of 18 kg/m 3 .
- the use of a particular type of graphite is also known, which is called expandable graphite, which increases its volume at high temperatures, creating a protection barrier against fire; it is sometimes added in varnishes or adhesives.
- a self-supporting panel which is easy to transport and cut in the construction site by a single person according to need, this panel being rigid and suitable for supporting the laying of tiles, also in the presence of water and/or damp.
- the aim is to make in an easier and more inexpensive way compared to said bricks and also in a safer and more durable way compared to conventional plasterboard, any configuration of wall, niche, shaped space, floor or subfloor located in damp environments and coated with tiles, as in the case of bathrooms, saunas, laundry rooms and kitchens.
- such superficial coating is made up of various layers having diversified functions and being combined one another, so as to obtain an insulating panel which is resistant to damp and bending and it is usable as a constructive element to make up infill walls, niches or floors, also in damp environments such as bathrooms and saunas.
- some panels provide an external coating which improves the grab of glues or cement mortars, so as to support the gluing of tiles or plasters directly laid on the panel surface.
- said multi layer coating consists of at least one waterproof layer, such as a plastic plate or a waterproof paper, which is coupled to permeable layers facilitating the gluing and also increasing the structural rigidity, such as for example a non-woven fabric or a net.
- a waterproof layer such as a plastic plate or a waterproof paper
- permeable layers such as for example a non-woven fabric or a net.
- a first permeable layer is joined in adhesion to the foamed core by means of an adhesive material, while the other is placed on the outside to facilitate the anchorage of glues or cement mortars for tiles or plasters; solutions are also known wherein such layers are inverted or there are additional layers.
- Dl proposes an insulating panel in expanded polystyrene provided with a coating for fire protection in a resin of the epoxy type, which is obtained by a polymerization reaction of a mixture made up of a first compound including liquid epoxy resin, ammonium polyphosphate, and other components such as pentaerythritol or pentaerythritol-based esters and polyols, and of a second compound with at least one hardener for epoxy resins.
- a resin of the epoxy type which is obtained by a polymerization reaction of a mixture made up of a first compound including liquid epoxy resin, ammonium polyphosphate, and other components such as pentaerythritol or pentaerythritol-based esters and polyols, and of a second compound with at least one hardener for epoxy resins.
- D2 describes a thermal or acoustic insulating panel which is provided with a coating layer having a thickness of between 0.2 mm and 1 mm, which comprises an organic and/or inorganic binder and with 45% of charge weight containing water in the form of crystal and/or hydrate, such as a metallic hydroxide, a hydrate of a metallic silicate, a metallic salt, a metallic sulfate and a possible additive including a pigment, a dye, fibers and/or a flame retardant.
- a coating layer having a thickness of between 0.2 mm and 1 mm, which comprises an organic and/or inorganic binder and with 45% of charge weight containing water in the form of crystal and/or hydrate, such as a metallic hydroxide, a hydrate of a metallic silicate, a metallic salt, a metallic sulfate and a possible additive including a pigment, a dye, fibers and/or a flame retardant.
- D3 proposes a multi-layer laminated structure with improved characteristics of fire resistance, which provides a central layer of an insulating material and protective coating layers on both opposite faces like a sandwich panel; they comprise a fibrous reinforcement which is joined with an adhesive layer of the inorganic type and an external layer of an organic resin, wherein said adhesive layer is made of water, magnesium sulphate or magnesium chloride, magnesium oxide and sodium silicate, whereas said resin is a gel-coat based on polyester resin modified with aluminum hydroxide.
- D4 instead, describes the structure of a thermal insulating panel in a polymeric foam, with an external coating of the multi-layer type which is provided with an excellent thermal stability being made up of a first layer of the non-cellular type in a heatproof thermoplastic material, and of a second non-cellular layer in a polylactic acid- based resin which acts as barrier, being able to reduce the loss of insulating capacity due to the progressive replacement of the expanding agents of the internal foam with atmospheric gases.
- sandwich panels are also known with a foamed core and a coating in glass fiber; for example, D5 proposes a panel for construction in XPS with a multi-layer coating wherein the first layer contacts the foamed core and consists of a two-component epoxy resin on which fiberglass is sprayed so as to form an intermediate layer of casually placed and flattened fibers, and with a smooth top layer of a two-component epoxy resin.
- D6 describes, instead, a multi-layer building panel, usable as a constructive element of walls, partitions, or false ceilings, which is made up of a very lightweight core in expanded polystyrene or polyurethane coated with a resistant layer made with a resin directly applied on said core in combination with a catalyst and with particular charges, such as silica sand, corundum, crushed glass or silicon carbide.
- panel for construction having similar functions but being more inexpensive and easier to produce
- the protective coating is in a single-layer and multifunctional, and it is directly formed and/or applied in a continuous production line, without interposed layers for the adhesion to the foamed core and without superposed layers for the grab of the tiles.
- a simplified structure of panel is not known and is desirable with a cooperating and rigid single-layer coating, suitable for damp environments, which contextually ensures an excellent resistance to bending, to damp, and also to high temperatures, and which is easy and clean during working in the construction site, and furthermore it is provided with an outer surface compatible with the common glues and/or cement mortars for tiles, directly acting as grab interface.
- all these functions are performed by various layers, each time coupled one on the other according to their function.
- one resin layer directly applied to the insulating panel can be useful and advantageous for the aims of the present invention, having a rigid consistency and also being able to protect from high temperatures.
- known solutions with at least one resin layer or with other compounds pre-formed in sheets or directly applied provide complex working and/or disadvantageous materials.
- the panels in glass fiber or with epoxy-based resins are considered obsolete due to their overall manufacturing costs, due to complex working and equipment and/or due to some dangerous ingredients, such as for example pentaerythritol according to D1 or polyester resin in D3.
- a rigid panel (10) provided with a high resistance to bending, impacts, damp and which is also suitable for supporting the direct grab of glues or cement mortars.
- the panel is usable as a constructive element for walls, infdl walls, floors or subfloors, it supports the direct laying of tiles or plasters, and it is suitable for damp environments as in the case of bathrooms, saunas, laundry rooms or kitchens.
- a first aim is to obtain an insulating panel for construction which is extremely resistant, rigid and self-supporting, so as to be usable as a constructive element for building in an easy and inexpensive way the different structures and the completion works, which are currently needed in modem interior architecture. For example, it is suitable for building walls, partitions, infill walls, floors, subfloors, shower spaces and niches, it is suitable for making in an easy and inexpensive way the different structures and the completion works, which are currently needed in the modem interior architecture.
- a second aim is to obtain a rigid panel for construction, which also acts as barrier to vapor.
- a third aim is to obtain a rigid panel for construction which is provided with an outer surface ready for the finishing and compatible with cement mortar.
- common ceramic coatings, or any finishing tile or plaster can be directly applied by using glues or cement mortars of the conventional and known type, without the need for interposing any film, net, grab primer or any material to facilitate the adhesion.
- a rigid coating layer is provided, which can be superficially worked during the production phase, so as to further increase the resistance to tearing of glues or cement mortars. The proposed solution considerably facilitates the work in the construction site and allows to considerably reduce time and costs for completing a construction manufacture.
- a fourth aim is to obtain a rigid panel for construction, which is easy to transport, to place and to work in the construction site by a single operator using the common working tools without releasing dusts in the environment.
- a fifth aim of this invention is to make a multi-layer panel having an optimized structural configuration, being made up of a minimum number of layers, and namely only three layers which are symmetrically joined without interposed glues, using only one material for the foamed core and only one material for the coating; said configuration being suitable for the continuous industrial production with high production volumes, high repeatability and end quality, and with considerably reduced costs.
- a sixth aim is to obtain a rigid panel for construction in XPS polystyrene or expanded polyurethane, which is also provided with a good resistance to fire.
- an aim is also to avoid the above-mentioned drawbacks with an innovative panel for construction, which allows to contextually obtain all the above-mentioned advantages, and which is therefore versatile in use, and it also considerably facilitates the work in the construction site, the material procurement and the transport.
- a thin panel like a sheet is proposed in a foamed material with faces coated of a thin rigid layer, structurally cooperating, obtaining a constructive element, which is provided with a high resistance to bending and to impacts, it is self-supporting despite having a limited weight, it has reduced production costs, it can be worked in the construction site like any panel for thermal insulation, it can be directly coated with tiles or plaster, and it is also usable in damp environments as it is unaffected by water or damp.
- an innovative panel for construction has to be made with a single-layer coating, which can be produced in an inexpensive way with equipment for continuous production and which has excellent performance characteristics which are advantageously combined one another, being contextually provided with a high resistance to bending, a high resistance to vapor permeability and to damp, a high compressive strength, a high resistance to tearing also called pull-out with reference to the grab of glues and/or cement mortars, in addition to a good resistance to high temperatures.
