Definitions

  • the present invention refers to coating or flooring elements and panels, as an example for parquet and the like, and in particular it concerns a coating or flooring element and a method for carrying out said element.
  • the main object of the present invention is to propose a flooring element which has both the advantages of the wood ones, referring in particular to the possibility to walk barefoot thereon without feeling cold, differently from the marble and ceramic floor, and the high resistance to water and to trampling typical of the ceramics and marbles, in order to be used in substitution thereof.
  • Another object is to propose a water resistant element, to be used in several applications, like, as an example, panels for winnowed or not winnowed roof tiles, which do not need protective waterproof sheath, street furniture, container or truck goods or train platforms, pleasure-boat or ship wharfs, bulkhead or furniture thereof, swimming pools boundaries floor, bathroom coatings and floors, garden furniture, bungalows, prefabricated wood houses, winnowed walls, shelters, grazing animals housings, sound insulating barriers, guardrails with low landscape environmental impact, beach furniture, terrace and balcony floors, gym floors, raised floors etc..
  • Another object is to propose a material, differently from the wood parquet and to the conglomerate floors, lacking in formaldehyde, phenol, styrol urea, which are cancerogenous both in the forming step and for the whole life time of the finished products, thus proposing a biocompatible product.
  • Another object is to use local resources fit only to the waste-to-energy process, in a more profitable manner, and respecting the natural environment.
  • the raw materials used for carrying out the element of the present invention is a vegetable product or a plurality of vegetable products or the by-products thereof, like a wood whose oil content make it waterproof, olives stones, walnuts or almonds shells, coconut shells, residual of the extraction of the oil from seeds, or wood fibres with high silicon contents, rice glumes and glumelles, reeds and bamboos, the mud of the beer fermentation and other types of woods or seeds, made waterproof by impregnation.
  • the first step consists in chopping up wood fibres, in order to make them have a granulometry fit to carry out a perfectly closed conglomerate. Then the chopping up is followed by a mixing step with unsaturated fatty acid (preferably linseed oil) in small percentages (up to 3-10% preferably about 5 %) and then with an organic ligand polyurethane bicomponent in a measure ranging from 5 to 20%, preferably 10%.
  • unsaturated fatty acid preferably linseed oil
  • organic ligand polyurethane bicomponent in a measure ranging from 5 to 20%, preferably 10%.
  • the mixture is then deposited in an uniform layer onto a moulding support, for example comprising a conveyor belt, and pre-compacted under several contrasting rolls where the lower rolls are placed on the same plane under the conveyor belt and the upper rolls are placed in a tilted plane in the advancing direction, then a predetermined blade portion of the mixture is picked up from the conveyor by means of a sucking plane provided with perimetrical punch and said portion is deposited onto a flat mortarboard, or tray, provided with a detaching agent.
  • a moulding support for example comprising a conveyor belt
  • pre-compacted under several contrasting rolls where the lower rolls are placed on the same plane under the conveyor belt and the upper rolls are placed in a tilted plane in the advancing direction, then a predetermined blade portion of the mixture is picked up from the conveyor by means of a sucking plane provided with perimetrical punch and said portion is deposited onto a flat mortarboard, or tray, provided with a detaching agent.
  • This mortarboard is placed between the planes of a multi-opening press whose characteristic is to provide a continuous step process thanks to the possibility to open a space while the others are kept in pressure, allowing the product to stay for the relatively long period of time needed to the complete polymerization of the bicomponent ligand.
  • the planes of the press covered by a detaching agent like the Mayler film, are heated to speed up the polymerization time that will be much short in function of the supplied temperatures, as an example for temperatures ranging from about 60° C and about 70° C there will be polymerization time ranging from 15 to 20 minutes, for temperatures of about 200° C the polymerization time is about three minutes.
  • the depositing of the mixture blade is carried out directly onto the Mayler conveyor tape in line that overflows both at the inlet and the outlet of the continuous press avoiding the pre-compacting and the transferring of the mixture blade and the mortarboard comebacks, obtaining the continuous forming which will be separated with an in running cutting in order to obtain a predefined size at the outlet of the press.
  • the surface fit to the gluing in the laying may be carried out with grooves prints, also orthogonally placed, in order to make the gluing easier, predisposing the mortarboards with said prints, in the same manner an in view surface with bass-relief having a decorative or anti-slipping effect may be obtained.
  • coarse-grain fragments of colored wood or other coarse-grain fragments of organic materials like colored plastic materials or light reflecting materials as CD, mother-of-pearl fragments, and bleaching or coloring oxides may be included in the mixture.
  • the conglomerate panels or elements are finished with a proper smoothing, in order to highlight the inclusions, waxing or overlapping with a fireproofed transparent paint of high resistance to the abrasion (PEI 4) and which cannot be soiled by any agent.
  • PEI 4 fireproofed transparent paint of high resistance to the abrasion
  • Particularly a superficial decoration may be carried out by digital printing both onto the flat surface or onto the surface with relieves, or by other systems in order to confer any desired aspect, comprising the high-fidelity reproductions of precious woods or briar- roots, or by means of the printing used in ceramics, and subsequent overlapping with transparent fireproofed paint.
  • wood flooring or covering is the possibility of laying also onto non perfectly dried block of stones or the laying onto cement mortars as used for the stone materials.
  • Another advantage is the laying without adhesives of floating flooring with joints without the danger of disagreeable shrinkages or deformations.
  • unsatured fatty acid preferably linseed oil
  • enriches the oily wood making it more water-repellent
  • the already water-proofed fibres rich in silicon or other hygroscopic, or porous and fit to keep or absorb humidity, wood fibres they are impregnated and made water-repellent.
  • the use of the bicomponent polyurethane ligand resin, or of a resinous substance which may be hardened, allows to bind, contrary to the other used ligands, the fibres impregnated with unsatured fatty acid, while it would act as a detaching agent for them, it forms with the second component of the polyurethane resin (the polyalcohol), insoluble and steady polyesters.
  • the polyalcohol the polyurethane resin
  • Exploiting said ligand property also hard woods, considered particular waste, may be use, like railway wood crossbars impregnated with creosote which will bind contrarily to the polyalcohol, to the diisocyanate, forming always an insoluble and steady polyester, allowing to recover a great resource fit to a particular disposal.
  • the proposed objects have been realized carrying out a wood material fit to the flooring in substitution of wood parquet, which derives from the deforestation.
  • This wood element or material may be applied like the stone materials, usable in substitution of them for the facing or the decoration by printing a subsequent depositing of fireproofed paint which may not be soiled and resistant as a ceramic surface, or other uses, waterproof, lacking in formaldehyde, phenol, monomelic styrol fumes both in the forming step regarding the worker and in the finished product regarding the customers, using rich local resources not yet exploited, respecting the environment.
