Definitions
- the present invention relates to a wall, furniture or floor panel.
- Wall, furniture or floor panels are known from various materials such as stone, ceramics, wood, fiber material, cork, linoleum or plastic. Their underside is connected to a substrate, for example by gluing, and they serve functional and optical purposes, for example as decorative, easy-to-clean surfaces.
- Previously known wall, furniture or floor panels are available as bulk goods in a predetermined design and in a certain size in stock at a manufacturer, a wholesaler or in a hardware store and are bought by the end customer or by his commissioned craftsman and placed in the appropriate room nes building or on a piece of furniture. Due to the fixed package sizes, there are often considerable residual quantities that can no longer be used.
- a wall, furniture or floor panel is constructed in such a way that it consists of a castable, spatulatable or sprayable natural resin or synthetic resin such as epoxy resin, polyester resin or polyurea that can be processed in a mold. Due to the shape, any size and contour of a wall, furniture or floor panel can be produced.
- the natural resin or synthetic resin is a liquid plasticizer, in the case of epoxy resin or polyester resin, an alcohol, in particular bio-ethanol, is added, whereby the desired hardness or softness of the wall, furniture - or base plate can be adjusted. With increased plasticizer admixture, the finished wall, furniture or floor panel becomes softer. Little or no addition of plasticizers leads to greater hardness in the finished wall, furniture or floor panel.
- polyurea the wall, furniture or floor panels are injected into the molds in one or more layers by a hot injection device as one or two components. Wall, furniture or floor panels made of polyurea are characterized by rapid curing and the resulting short cycle times in production as well as excellent wear resistance and excellent resistance properties to chemicals. The molds can be sprayed with a primer before the plastic material is introduced to make it easier to demould the finished wall, furniture or floor panels.
- the upper side of the wall, furniture or floor panel is particularly preferably provided with a three-dimensional structure which can be impressed into the upper side of the wall or floor panel particularly advantageously by means of a three-dimensional structure of the mold with a complementary shape.
- the three-dimensional structural structure of the form can be formed by a flamed wooden panel that is directly a surface of the mold or from which a silicone impression was previously taken, which then forms a surface of the mold.
- the upper side of the wall, furniture or floor panel preferably has at least one color which can advantageously be mixed with the natural resin or synthetic resin before it is poured, so that a completely colored wall, furniture or floor panel is produced.
- two or more colors can be applied to the upper side and processed there by wiping or squeegeeing into a marbling.
- Different templates can also be used to apply the color in order to make certain color patterns clearly reproducible.
- Structures can also be produced, for example in the form of a grain when the colors are introduced, which are then covered, for example, by a translucent color and thereby made visible.
- fillers such as very fine cotton flakes, quartz flour or small glass beads can be introduced into the natural resin or synthetic resin to create a structure.
- the finished wall, furniture or floor panels adhere to smooth surfaces such as glass without the need for adhesives. However, it can also be attached using dispersion adhesive, double-sided adhesive tape or adhesive adhesive.
- a major advantage of the wall, furniture or floor panels according to the invention in order to world and resource aspects is the complete recyclability after the intended useful life.
- the wall, furniture or floor panels can be chopped up into small pieces and melted down again, with the floor coverings that have been customary up to now usually only being thermally usable in waste incineration plants.
- a further aspect of the present application is provided by a method for producing one of the aforementioned wall, furniture or floor panels with a panel-shaped main body.
- Fig. 1 is a front view of a rectangular in the embodiment shown
- FIG. 2 shows a section through the wall, furniture or floor panel according to FIG. 1 with attachment to a wall;
- FIG. 3 shows a mold with a structure and a wall, furniture or floor panel produced in the mold by casting.
- Fig. 1 shows a rectangular wall, furniture or floor panel 100 made of a natural resin or synthetic resin, such as in particular an epoxy resin, polyester resin or polyurea - letz teres also known as polyurea - for attachment to a wall 140 or egg nem floor of a room in a building or on a piece of furniture.
- a wall, furniture or floor panel 100 made of a natural resin or synthetic resin, such as in particular an epoxy resin, polyester resin or polyurea - letz teres also known as polyurea - for attachment to a wall 140 or egg nem floor of a room in a building or on a piece of furniture.
- the shape and size of a wall, furniture or floor panel 100 according to the invention are extremely variable. These can be produced in any form, both small and large.
- the softness or hardness of the wall, furniture or floor panel 100 can be adjusted within a wide range by adding a softener, such as an alcohol, which is particularly advantageously formed by a bioethanol.
- very hard, abrasion-resistant floor panels 100 can be produced, but with a correspondingly higher admixture of plasticizers, very soft wall panels can also be produced, which have an impact-damping and sound-absorbing effect.
- hardeners in particular in a two-component hot spray device, curing in the mold can be accelerated and the cycle time during production can thus be accelerated.
- polyurea two-component systems made of aliphatic amines and isocyanates that can be processed in a two-component mixing plant also have extremely short curing times of just a few seconds.
- Wall, furniture or floor panels 100 made of polyurea according to the invention have a permanently high elasticity and tear resistance combined with high chemical resistance, which means that they are also suitable for use on industrial floors or in laboratories.
- the wall, furniture or floor panel 100 has an upper side 110 facing a room and an underside 120 which can be connected to the wall 140 .
- the connection to the wall 140 is preferably effected by gluing, for example with a PU adhesive, a polystyrene adhesive, a dispersion adhesive, an adhesive adhesive or a double-sided adhesive tape.
- the wall, furniture or floor panels 100 with their likewise very smooth underside, adhere to smooth surfaces of a wall 140—such as glass—by purely mechanical adhesion, even without adhesive.
- a three-dimensional structure 112 is preferably embossed into the upper side 110, which creates a special visual impression and which, when used as a wall panel, also results in an improved sound-absorbing property.
- FIG. 3 shows a mold 130 which is open at the top and whose bottom has a three-dimensional structure 132 .
- the three-dimensional structure 132 can be formed either directly from a flamed wood, for example, or by means of a silicone plate, by means of which a print is taken from the structured surface of a flamed wood.
- the natural resin or synthetic resin in particular an epoxy resin or polyester resin or polyurea
- the upper side 110 of the wall, furniture or floor panel 100 that forms after curing takes on a structure 112 that complements the structure 132 of the mold.
- the lower side 120 forms a smooth horizontal surface the end.
- the wall, furniture or floor panel 100 After removal from the mold 130, the wall, furniture or floor panel 100 thus has the desired smooth underside 120 for a planar connection to the wall 140 or to a floor of a room.
- the upper side 110 on the other hand, has the three-dimensional structure 112 and, on the one hand, thereby gains a particularly unique optical appearance and, on the other hand, due to the uneven structure 112 also outstanding acoustic insulation properties.
- the mold 130 can also have a flat bottom, which then forms the smooth underside 120 of the wall, furniture or floor panel 100, in deviation from the illustration in FIG. If the top side 110 is not yet made of hardened natural resin or synthetic resin, in particular epoxy resin or polyester resin, then lying on top in the mold 130, a three-dimensional structure can be introduced using a brush, a comb, a notched spatula or any other tool.
- At least one color can also be introduced into the natural resin or synthetic resin, in particular epoxy resin or polyester resin or the polyurea, at least in the region of the upper side 110 . If at least two colors are introduced, these can be processed to a unique marbling by wiping if the natural resin or synthetic resin, in particular epoxy resin or polyester resin, has not yet hardened.
- Suitable natural resins are tree resins, natural rubber, rosin, sandarak and mastic.
- synthetic resins include all other synthetic resins that are produced by polymerization, polyaddition or polycondensation reactions in accordance with DIN 55958 (December 1988).
- synthetic resins include all other synthetic resins that are produced by polymerization, polyaddition or polycondensation reactions in accordance with DIN 55958 (December 1988).
- natural resin or synthetic resin used in addition to the alcohol already mentioned, in particular bio-ethanol, oil, ammonia solution, styrene or turpentine are also suitable as plasticizers.
- One-component or two-component polyurea can be introduced into the molds in one or more layers using a hot injection device at injection temperatures of 75 to 85 °C.
- suitable hardeners such as oxazolidine
- the individual layers harden after about 15 seconds, so that short cycle times can be achieved, which are also advantageous for industrial production.
- Two-component systems made from aliphatic amines and isocyanates, which can be fed to the spraying device via a two-component mixing system have pot lives of just a few seconds. A further increase in material strength can also be achieved here, for example, by incorporating nanoparticles.
- the technology described above for producing a wall, furniture or floor panel 100 according to the invention can also be transferred to the production of furniture panels or picture frames or at least to the surfaces thereof.
- the panels made of a natural resin or synthetic resin in particular epoxy resin or polyester resin or made of polyurea, can be designed to be self-supporting with a greater thickness, or thinner panels are produced, which are connected to a carrier panel made of wood, pressed wood material or metal, for example by gluing will.
- Such plate-shaped products, in particular with a three-dimensional structure embossed in a mold on their upper side, are also covered by the protection of the invention.
- a device for producing wall, furniture or floor panels 100 according to the invention has, for example, a mold 130 with a size of 2m ⁇ 2m.
- a release agent is first introduced into this so that the wall, furniture or floor panels 100 can also be easily removed from the mold 130 after curing.
- the underside of the mold 130, on which the later upper side 112 of the wall, furniture or floor panels 100 is formed, can have a structure 132 through which the finished wall, furniture or floor panels 100 have, for example, an anti-slip property exhibit.
- the structure 132 can, in addition to the embodiment already described
- the shape of flamed wood can also be brushed wood or have a leather-like structure.
- a natural resin or synthetic resin, for example polyurethane, is then introduced--if desired with the additional introduction of fillers or color materials--into the mold 130. It can be introduced by pouring by hand and evenly distributing it with a notched trowel. Optionally, another layer of polyurethane in a different color can then be applied. The form 130 is then pushed into an oven for about 30 minutes, where the polyurethane hardens at 60-80°C.
- the finished panel which is initially large, is then cut using an industrial plotter to produce the desired size and shape of the finished wall, furniture or floor panels 100 .
