Titolo: FINTA PELLE Title: Faux leather
D E S C R I Z I O N E DESCRIPTION
Il presente trovato ha come oggetto una finta pelle, cio? un materiale che possa sostituire la pelle naturale in numerose applicazioni (presentando caratteristiche fisico-tecniche ed estetiche, nonch? meccaniche, analoghe/comparabili o anche superiori a quelle della pelle naturale). La similpelle, o finta pelle, ? un materiale che non ha componenti di origine animale. Si tratta di un prodotto industriale composto generalmente (ma non tassativamente) da un supporto tessile (o similare) sulla quale viene distribuito almeno un film di materiale polimerico: sulla superficie esterna del film polimerico possono essere impresse meccanicamente delle irregolarit? superficiali del tipo di quelle tipiche delle diverse pelli, in modo da riprodurre fedelmente la superficie della vera pelle. The present invention has as its object a fake leather, that is? a material that can replace natural leather in numerous applications (presenting physical-technical and aesthetic, as well as mechanical, characteristics similar/comparable or even superior to those of natural leather). Is imitation leather, or imitation leather, ? a material that has no components of animal origin. It is an industrial product generally (but not necessarily) composed of a textile support (or similar) on which at least one film of polymeric material is distributed: can irregularities be mechanically imprinted on the external surface of the polymeric film? surfaces of the type typical of different leathers, in order to faithfully reproduce the surface of real leather.
Gli strati in materiale polimerico, opportunamente sovrapposti, permettono di ottenere colorazioni del tutto simili a quelle della pelle naturale. The layers of polymeric material, appropriately overlapped, allow you to obtain colors that are completely similar to those of natural leather.
Quest'ultima per? presenta delle irregolarit? di pigmentazione (ad esempio la presenza di piccole aree localizzate di differente colorazione) che non ? possibile riprodurre fedelmente con i polimeri (in quanto i pigmenti in essi dispersi tendono a conferire una colorazione uniforme). The latter though? does it have any irregularities? of pigmentation (for example the presence of small localized areas of different colouration) which is not? possible to reproduce faithfully with polymers (as the pigments dispersed in them tend to give a uniform color).
E' noto, dal Brevetto EP3051023 il ricorso a particelle di sughero disperse nei materiali polimerici stratificati per conferire un aspetto estetico alla finta pelle maggiormente assimilabile a quello della pelle naturale: purtroppo per? la presenza di sughero (materiale naturalmente igroscopico) pu? generare delle irregolarit? dovute all'assorbimento di piccole quantit? di acqua (formazione di bolle). Tali bolle costituiscono punti di innesco per rotture e lacerazioni localizzate del materiale. Inoltre, ottenere una dispersione omogenea del sughero ? estremamente complesso. It is known from Patent EP3051023 the use of cork particles dispersed in stratified polymeric materials to give an aesthetic appearance to imitation leather that is more similar to that of natural leather: unfortunately, however? the presence of cork (naturally hygroscopic material) can generate irregularities? due to the absorption of small quantities? of water (formation of bubbles). These bubbles constitute trigger points for localized breakages and lacerations of the material. Furthermore, obtain a homogeneous dispersion of the cork? extremely complex.
E' inoltre noto, dal brevetto EP3666518, il ricorso ad una combinazione di cariche lignocellulosiche (idonee a conferire un aspetto estetico simile a quello della pelle naturale) e microsfere (destinate a avviare una fase di espansione nei polimeri che favorisce la necessaria dispersione delle cariche lignocellulosiche). La fase di espansione indotta dalle microsfere, per?, costituisce una notevole complicazione realizzativa, perch? deve essere opportunamente controllata. It is also known, from patent EP3666518, the use of a combination of lignocellulosic fillers (suitable for giving an aesthetic appearance similar to that of natural leather) and microspheres (intended to initiate an expansion phase in the polymers which favors the necessary dispersion of the fillers lignocellulosic). The expansion phase induced by the microspheres, however, constitutes a notable manufacturing complication, because? must be appropriately controlled.
Compito principale del presente trovato ? quello di risolvere i problemi sopra esposti, proponendo una finta pelle di aspetto analogo a quello di una pelle naturale. Main task of the present invention? that of solving the problems stated above, proposing a fake leather with an appearance similar to that of natural leather.
Nell'ambito di questo compito, uno scopo del trovato ? quello di proporre una finta pelle con ottimali propriet? meccaniche. Within the scope of this task, one purpose of the invention is? is to propose a fake leather with optimal properties? mechanical.
Un altro scopo del trovato ? quello di proporre una finta pelle che non sia soggetta alla formazione di bolle. Another purpose of the invention? that of proposing a fake leather that is not subject to the formation of bubbles.
Un altro scopo del trovato ? quello di proporre una finta pelle in cui sia semplice la dispersione degli additivi destinati a conferire l'ideale aspetto estetico. Another purpose of the invention? that of proposing a fake leather in which the dispersion of the additives intended to give the ideal aesthetic appearance is simple.
Un altro scopo del trovato ? quello di proporre una finta pelle di sostanzialmente semplice produzione, che non richiede cio? misure specifiche per il contenimento di fasi espansive addizionali. Another purpose of the invention? that of proposing a fake leather that is essentially simple to produce, which does not require that? specific measures to contain additional expansionary phases.
Un altro scopo del trovato ? quello di proporre una finta pelle idonea ad applicazioni di pregio quali il rivestimento di interni nel settore automotive o in altri con simili esigenze. Another purpose of the invention? that of proposing an imitation leather suitable for high-quality applications such as interior coverings in the automotive sector or others with similar needs.
Un altro scopo del trovato ? quello di proporre una finta pelle comprendente additivi per il conferimento dell'idoneo aspetto estetico di tipo a basso impatto ambientale. Another purpose of the invention? that of proposing a fake leather including additives to give the suitable aesthetic appearance of a low environmental impact type.
Un altro scopo del trovato ? quello di proporre una finta pelle avente elevata resistenza all'usura ed alle radiazioni luminose. Another purpose of the invention? that of proposing a fake leather with high resistance to wear and light radiation.
Ulteriore scopo del presente trovato ? quello di realizzare una finta pelle di costi contenuti relativamente semplice realizzazione pratica e di sicura applicazione. Further purpose of the present invention? that of creating a low-cost imitation leather that is relatively simple, practical and safe to apply.
Questo compito e questi scopi vengono raggiunti da una finta pelle di tipo stratificato comprendente almeno uno strato principale (2a, 2b, 2c) in materiale polimerico costituito almeno parzialmente da miscele di cloruro di polivinile in percentuale in massa compresa tra 30% ed 80% addizionato con almeno un agente plastificante in percentuale in massa compresa tra 15% ed 55%, caratterizzata dal fatto che This task and these purposes are achieved by a layered type artificial leather comprising at least one main layer (2a, 2b, 2c) in polymeric material constituted at least partially by mixtures of polyvinyl chloride in a mass percentage of between 30% and 80% with added with at least one plasticizing agent in a mass percentage between 15% and 55%, characterized by the fact that
- detto almeno uno strato (2a, 2b, 2c) comprende cariche derivate da organismi viventi, con esclusione del sughero, disperse nello stesso, dette cariche presentano dimensioni, in tutte le direzioni, inferiori a 900 ?m, ed sono presenti in percentuale in massa inferiore al 20%. - said at least one layer (2a, 2b, 2c) includes fillers derived from living organisms, with the exception of cork, dispersed in the same, said fillers have dimensions, in all directions, less than 900 ?m, and are present in percentage in mass less than 20%.
