TITOLO TITLE

MATERIALE COMPOSITO STRATIFICATO CON TRATTAMENTO LAYERED COMPOSITE MATERIAL WITH TREATMENT

SUPERFICIALE IN GRAFENE SURFACE IN GRAPHENE

DESCRIZIONE DESCRIPTION

Il presente brevetto è attinente ai materiali stratificati ed in particolare concerne un nuovo materiale stratificato con strato di supporto in materiale espanso, particolarmente destinato alla produzione di borse, calzature, articoli di pelletteria, elementi o oggetti o complementi d'arredo. The present patent relates to layered materials and in particular concerns a new layered material with a support layer in expanded material, particularly intended for the production of bags, footwear, leather goods, elements or objects or furnishing accessories.

Il presente brevetto riguarda anche il procedimento per ottenere detto materiale stratificato. The present patent also relates to the process for obtaining said layered material.

Sono noti i materiali stratificati, ottenuti dall'accoppiamento di due o più strati di materiali identici o differenti. Stratified materials are known, obtained by coupling two or more layers of identical or different materials.

Sono noti tessuti accoppiati e/o stratificati, ottenuti dall'unione di due tessuti differenti allo scopo di sfruttare le caratteristiche singole di ciascun tessuto. Coupled and / or layered fabrics are known, obtained by joining two different fabrics in order to exploit the individual characteristics of each fabric.

Ad esempio, un primo tessuto è destinato alla parte interna del capo di abbigliamento ed è atto a mantenere il calore corporeo, mentre un secondo tessuto è destinato ala parte esterna del capo di abbigliamento ed è atto a permettere la traspirazione pur garantendo l'impermeabilità all'acqua. For example, a first fabric is intended for the internal part of the garment and is designed to maintain body heat, while a second fabric is intended for the external part of the garment and is designed to allow transpiration while guaranteeing waterproofing. 'water.

Sono anche noti materiali accoppiati dove uno degli strati può avere lo scopo di rinforzare il materiale stesso e/o di valorizzarlo esteticamente e/o di proteggerlo da abrasione o usura, eccetera. Coupled materials are also known where one of the layers can have the purpose of reinforcing the material itself and / or enhancing it aesthetically and / or protecting it from abrasion or wear, etc.

Forma oggetto del presente brevetto un nuovo materiale composito stratificato che comprende un primo strato di supporto in materiale espanso, particolarmente destinato alla produzione di borse, calzature, articoli di pelletteria, elementi o oggetti o complementi d'arredo e un trattamento superficiale in grafene. The subject of the present patent is a new layered composite material which comprises a first support layer in expanded material, particularly intended for the production of bags, footwear, leather goods, elements or objects or furnishing accessories and a graphene surface treatment.

E noto il grafene, che consiste in uno strato di atomi di carbonio legati tra loro che realizzano uno strato sottile dell'ordine dell'atomo, ha elevate caratteristiche di resistenza meccanica, e in particolare di resistenza all'abrasione. It is known that graphene, which consists of a layer of carbon atoms bound together which form a thin layer of the order of the atom, has high characteristics of mechanical resistance, and in particular of resistance to abrasion.

Un vantaggio del presente trovato è quello di poter essere utilizzato in vari possibili applicazioni, grazie alle sue caratteristiche di densità che gli conferisce una conformazione volumetrica di particolare valenza tecnica ed estetica. An advantage of the present invention is that it can be used in various possible applications, thanks to its density characteristics which give it a volumetric conformation of particular technical and aesthetic value.

Inoltre, grazie allo strato in materiale espanso, combinato con il trattamento superiore in grafene, il nuovo materiale può essere variamente sagomato e quindi utilizzato per realizzare oggetti sagomati, particolarmente nel settore della pelletteria, con borse, calzature e elementi e complementi d'arredo. Furthermore, thanks to the layer of expanded material, combined with the superior graphene treatment, the new material can be shaped in various ways and therefore used to create shaped objects, particularly in the leather goods sector, with bags, footwear and furnishing elements and accessories.

Questi ed altri scopi, diretti e complementari, sono raggiunti dal nuovo materiale composito stratificato con strato di supporto in materiale espanso, comprendente almeno due strati di cui un primo strato di supporto in poliuretano accoppiato con uno strato sottile in tessuto o in TNT e dove su detto strato in tessuto o TNT viene depositato uno strato di grafene. These and other direct and complementary purposes are achieved by the new layered composite material with a support layer in expanded material, comprising at least two layers of which a first support layer in polyurethane coupled with a thin layer of fabric or TNT and where on said layer of fabric or TNT is deposited a layer of graphene.

Detto strato di rivestimento in grafene è destinato a rimanere a vista. Said graphene coating layer is intended to remain visible.

Detto strato in grafene può essere integrale, cioè ricoprire completamente detto strato in tessuto o TNT oppure, considerati i costi del grafene, può essere disposto a griglia, a linee intervallate o qualsiasi altra forma o decorazione che ricopra parzialmente detto strato in tessuto o TNT Said graphene layer can be integral, that is to completely cover said layer of fabric or TNT or, considering the costs of graphene, it can be arranged in a grid, with interspersed lines or any other shape or decoration that partially covers said layer in fabric or TNT.

Detto strato di supporto è per esempio un espanso o schiuma poliuretanica, ossia comprende una significativa percentuale di vuoti nel suo volume. Detto strato di supporto può anche essere a cellulazione aperta, ossia dove sia presente un percorso che unisce i volumi d'aria, o a cellulazione chiusa. I polimeri costituenti detto strato di supporto possono essere preferibilmente : poliuretano ma anche polietilene o EVA Said support layer is for example a polyurethane foam or foam, ie it comprises a significant percentage of voids in its volume. Said support layer can also be open cell, ie where there is a path that joins the volumes of air, or closed cell. The polymers constituting said support layer can preferably be: polyurethane but also polyethylene or EVA

Detto secondo strato tessuto o TNT può essere il poliestere o in Lycra. Said second fabric or non-woven layer can be polyester or Lycra.

Infine il nuovo materiale di rivestimento comprende lo strato superiore in grafene che può essere depositato per stampaggio, per colatura, o qualsiasi altro conveniente metodo. Finally, the new coating material comprises the graphene top layer which can be deposited by molding, casting, or any other convenient method.

Il materiale così ottenuto è quindi particolarmente adatto ad essere sagomato e impiegato nell'ambito delle borde, valigie, calzature, articoli di pelletteria, arredo, abbigliamento. The material thus obtained is therefore particularly suitable for being shaped and used in the field of borders, suitcases, footwear, leather goods, furniture, clothing.

In particolare il trattamento protettivo realizzato in grafene, posto superiormente a detto materiale composito, conferisce a detto elemento di rivestimento una particolare resistenza all'abrasione e all'attrito in quanto la conformazione della grafene risulta molto più resistente agli urti agli strappi rispetto al neoprene. In particular, the protective treatment made of graphene, placed above said composite material, gives said coating element a particular resistance to abrasion and friction since the conformation of graphene is much more resistant to impact and tearing than neoprene.

Altra caratteristica positiva del nuovo materiale di rivestimento consiste nella particolare densità del prodotto che lo rende più stabile rispetto ad un materiale di rivestimento con uno strato realizzato solo il neoprene permettendo sagomature non ottenibili con le tecniche note. Another positive feature of the new coating material consists in the particular density of the product which makes it more stable than a coating material with a layer made only of neoprene, allowing shapes that cannot be obtained with known techniques.

Altra caratteristica importante conferita della grafene come strato di trattamento finale consiste nelle alte capacità di resistenza all'abrasione questa caratteristica trova particolare impiego nella realizzazione di valigie che devono essere caricate sulle stive degli aerei o delle borse che possono strisciare possono venire a contatto con superfici graffianti come pavimenti o pareti e danneggiarsi con conseguente perdita di valore e di pregio estetico della borsa stessa. Another important feature conferred by graphene as a final treatment layer consists in the high abrasion resistance capacity this feature is particularly used in the production of suitcases that must be loaded on the holds of aircraft or bags that can crawl and can come into contact with scratching surfaces. such as floors or walls and be damaged with consequent loss of value and aesthetic value of the bag itself.

Considerati i costi del grafene nelle soluzioni preferite si prevede che la stesura del grafene sia parziale, per esempio una percentuale inferiore al 20%, in modo da lasciar intravedere lo strato inferiore preferibilmente di colori vivaci. Considering the costs of graphene in the preferred solutions, it is expected that the drafting of graphene is partial, for example a percentage of less than 20%, so as to allow a glimpse of the lower layer, preferably in bright colors.

In tal modo si possono realizzare decorazioni con conformazioni estetiche in infinite soluzioni. Anche con una percentuale ridotta di grafene della sua parte esterna superiore del nuovo materiale di rivestimento si raggiungono i risultati sopradescritti, in particolare la buona resistenza all'abrasione che aumenta il valore dell'oggetto che viene realizzato con tale strato di rivestimento in particolare borse valigie sedie e poltrone divani sedili e sedute in genere Queste sono le modalità schematiche sufficienti alla persona esperta per realizzare il trovato, di conseguenza, in concreta applicazione potranno esservi delle varianti senza pregiudizio alla sostanza del concetto innovativo. In this way it is possible to create decorations with aesthetic conformations in infinite solutions. Even with a reduced percentage of graphene of its upper outer part of the new coating material, the results described above are achieved, in particular the good resistance to abrasion which increases the value of the object that is made with this coating layer in particular bags and cases. chairs and armchairs sofas seats and seats in general These are the schematic modalities sufficient for the skilled person to realize the invention, consequently, in concrete application there may be variations without prejudice to the substance of the innovative concept.

Pertanto con riferimento alla descrizione che precede si esprimono le seguenti rivendicazioni. Therefore, with reference to the preceding description, the following claims are expressed.
