“Procedimento per la fabbricazione di manufatti di materiale conglomerato in forma di lastre contenente elementi decorativi†. â € œProcedure for the manufacture of manufactured articles of conglomerate material in the form of plates containing decorative elementsâ €.
DESCRIZIONE DESCRIPTION
La presente invenzione riguarda un procedimento per la fabbricazione di un manufatto di materiale conglomerato in forma di lastra o blocco impiegando tecnologie di compattazione già note nel settore dei materiali agglomerati. The present invention relates to a process for the manufacture of a manufactured article of conglomerate material in the form of a slab or block using compaction technologies already known in the field of agglomerated materials.
Come noto, questa tecnologia comprende una fase iniziale di preparazione di un impasto comprendente un granulato di materiale inerte, quale ad esempio un granulato ottenuto da materiali come granito, quarzo, feldspato, marmo, vetro oppure materiali ceramici. Il granulato viene quindi addizionato con un filler, ed un legante induribile quale ad esempio una resina od un cemento idraulico. As is known, this technology comprises an initial phase of preparation of a mixture comprising a granulate of inert material, such as for example a granulate obtained from materials such as granite, quartz, feldspar, marble, glass or ceramic materials. The granulate is then added with a filler and a hardenable binder such as a resin or a hydraulic cement.
L’impasto viene poi distribuito entro uno stampo e sottoposto ad un’azione di compattazione, spesso realizzata sottovuoto. The mixture is then distributed within a mold and subjected to a compacting action, often carried out under vacuum.
Lo stampo, contenente il manufatto compattato, viene trasferito ad una stazione nella quale viene fatto indurire il legante per ottenere così un manufatto solido e consistente. Tale stazione di indurimento sarà diversa a seconda del tipo di legante utilizzato. The mold, containing the compacted product, is transferred to a station where the binder is hardened to obtain a solid and consistent product. This hardening station will differ according to the type of binder used.
Se il manufatto à ̈ in forma di blocco, esso viene poi segato in lastre; le lastre vengono poi normalmente finite in superficie. If the artifact is in the form of a block, it is then sawn into slabs; the slabs are then normally finished on the surface.
E’ noto anche realizzare manufatti di agglomerato che contengono elementi decorativi, adatti quindi per la pavimentazione, il rivestimento o la decorazione d’arredo di ambienti particolari come ad esempio le hall degli hotel, negozi di vario tipo, oppure edifici residenziali. It is also known to make agglomerate artifacts that contain decorative elements, therefore suitable for flooring, cladding or furnishing decoration of particular environments such as hotel lobbies, various types of shops, or residential buildings.
A tale scopo, assieme al granulato per formare l’impasto, vengono aggiunti degli elementi decorativi che possono essere elementi semplici come ad esempio pezzi di vetro o specchio oppure elementi metallici quali l’ottone od altri ancora. For this purpose, together with the granulate to form the mixture, decorative elements are added which can be simple elements such as pieces of glass or mirror or metal elements such as brass or others.
Vengono realizzati manufatti di conglomerato che contengono al loro interno vetri decorativi colorati riflettenti comunemente denominati “Avventurina†, che arricchiscono il prodotto e lo rendono particolarmente attraente e piacevole ed indicato per ambienti come quelli sopra indicati. Conglomerate artifacts are made that contain colored reflective decorative glass commonly called â € œAventurineâ €, which enrich the product and make it particularly attractive and pleasant and suitable for environments such as those indicated above.
In EP 0.521.286 à ̈ anche stato proposto di inserire granuli trasparenti con superficie metallizzata a specchio ed eseguire una successiva operazione di levigatura della lastra. I granuli scoperti riflettono così internamente la luce. In EP 0.521.286 it has also been proposed to insert transparent granules with a mirror-metallized surface and perform a subsequent smoothing operation of the plate. The discovered granules thus internally reflect the light.
La metallizzazione à ̈ però costosa e l’effetto ottenuto à ̈ stato trovato insoddisfacente. However, metallization is expensive and the effect obtained was found unsatisfactory.
Quindi la tecnologia, sebbene consolidata, à ̈ in continua evoluzione e alla ricerca di miglioramenti per soddisfare le esigenze sempre più spinte del mercato, che richiede un prodotto non solo duraturo nel tempo ma un prodotto esteticamente sempre più gradevole e nel contempo economico, così da poter attrarre una clientela più numerosa e soddisfare le richieste che diventano via via sempre più esigenti. So the technology, although consolidated, is constantly evolving and looking for improvements to meet the increasingly demanding needs of the market, which requires a product that is not only lasting over time but an aesthetically pleasing and at the same time economical product, so to be able to attract a larger clientele and satisfy the requests that become more and more demanding.
Tuttavia, uno degli inconvenienti di questo tipo di prodotti à ̈ il loro costo, che aumenta in modo sensibile con l’uso di inserti preziosi, costituendo quindi un freno alla diffusione di prodotti. However, one of the drawbacks of this type of products is their cost, which increases significantly with the use of precious inserts, thus constituting a brake on the diffusion of products.
Lo scopo principale dell’invenzione à ̈ quindi quello di realizzare un manufatto di agglomerato, che sia dal punto di vista estetico particolarmente attraente e che abbia un costo accessibile così da poter trovare una larga diffusione d’impiego. The main purpose of the invention is therefore to create an agglomerate product, which is particularly attractive from an aesthetic point of view and which has an affordable cost so as to be widely used.
Lo scopo viene raggiunto da un procedimento per la fabbricazione di manufatti di materiale conglomerato lapideo, comprendente: The purpose is achieved by a process for the manufacture of artifacts of stone conglomerate material, comprising:
- una fase di preparazione di un impasto a partire da un granulato lapideo naturale e/o sintetico, un filler sottile ed un legante induribile; - a phase of preparation of a mixture starting from a natural and / or synthetic stone granulate, a thin filler and a hardenable binder;
- una fase di distribuzione dell’impasto così formato in uno stampo; - a distribution phase of the mixture thus formed in a mold;
- una fase di compattazione dell’impasto contenuto nello stampo; e - a compacting phase of the mixture contained in the mold; And
- una fase di indurimento del legante; - a hardening phase of the binder;
nel quale granuli di materiale trasparente ricoperti con un rivestimento comprendente glitter vengono aggiunti nell’impasto e, dopo la fase di indurimento, viene eseguita una azione di asportazione di materiale per ottenere una superficie del manufatto destinata a rimanere in vista sulla quale almeno alcuni granuli si affacciano con una propria superficie priva di glitter. in which granules of transparent material covered with a coating including glitter are added to the mixture and, after the hardening phase, a material removal action is performed to obtain a surface of the product destined to remain visible on which at least some granules they face with their own glitter-free surface.
Più specificatamente, dopo la fase di indurimento del legante e l’eventuale segagione in lastre, la superficie della lastra destinata a rimanere in vista viene sottoposta ad una successiva fase di lavorazione, che può essere di calibratura e levigatura, così che il rivestimento della porzione di detti granuli immersa sotto la superficie a vista del manufatto conglomerato crea un effetto riflettente sulla superficie in vista. More specifically, after the hardening phase of the binder and any sawing into slabs, the surface of the slab destined to remain visible is subjected to a subsequent processing phase, which can be calibration and smoothing, so that the coating the portion of said granules immersed under the visible surface of the conglomerate product creates a reflecting effect on the visible surface.
L’invenzione riguarda anche un manufatto di conglomerato lapideo ottenibile da un impasto comprendente un granulato lapideo naturale e/o sintetico, un filler sottile ed un legante induribile che viene distribuito entro uno stampo, sottoposto a compattazione e successivamente indurito, caratterizzato dal fatto di comprendere granuli di materiale trasparente parzialmente inglobati nel manufatto e affacciati con parte della loro superficie su una superficie del manufatto e aventi un rivestimento comprendente glitter sulla loro parte inglobata. The invention also relates to a stone conglomerate product obtainable from a mixture comprising a natural and / or synthetic stone granulate, a thin filler and a hardenable binder which is distributed within a mold, subjected to compaction and subsequently hardened, characterized by the fact of comprising granules of transparent material partially incorporated in the manufactured article and facing with part of their surface on a surface of the manufactured article and having a coating comprising glitter on their incorporated part.
Inoltre l’invenzione riguarda anche i granuli di materiale duro trasparente ricoperti con un rivestimento costituito da glitter. Furthermore, the invention also relates to granules of transparent hard material covered with a coating consisting of glitter.
Il glitter à ̈ un particolare prodotto in forma di scaglie/granelli riflettenti molto piccoli (brillantini) ben noto e ampiamente impiegato nei settori quali quello della verniciatura, della cosmetica e dell’abbigliamento allo scopo di ottenere un effetto estetico e/o decorativo. Glitter is a particular product in the form of very small reflective flakes / grains (glitter) well known and widely used in sectors such as painting, cosmetics and clothing in order to obtain an aesthetic and / or decorative effect.
E’ evidente che l’impiego di questi granuli di materiale rivestiti con glitter permette di ottenere una lastra di agglomerato che dopo la levigatura si presenta particolarmente gradevole dal punto di vista estetico, sia per la presenza di questi particolari elementi decorativi, sia perché gli elementi decorativi superficiali ossia quelli posizionati in prossimità della superficie a vista, creano un effetto riflettente dopo la levigatura della superficie che asporta almeno il glitter dalla loro superficie esposta. It is evident that the use of these granules of material coated with glitter allows to obtain an agglomerate slab that after polishing is particularly pleasant from an aesthetic point of view, both for the presence of these particular decorative elements, and because © the superficial decorative elements, ie those positioned in proximity to the visible surface, create a reflective effect after smoothing the surface that removes at least the glitter from their exposed surface.
Per rendere più chiara la spiegazione dei principi innovativi della presente invenzione ed i suoi vantaggi rispetto alla tecnica nota si descriverà di seguito, con l'aiuto dei disegni allegati, una possibile realizzazione esemplificativa applicante tali principi. Nei disegni: To clarify the explanation of the innovative principles of the present invention and its advantages with respect to the known art, a possible exemplary embodiment applying these principles will be described below, with the help of the attached drawings. In the drawings:
-figura 1 rappresenta una vista schematica parziale e in sezione di un manufatto, in una fase intermedia di lavorazione, ottenuto secondo l’invenzione; figure 1 represents a partial schematic and sectional view of an article, in an intermediate processing step, obtained according to the invention;
-figura 2 rappresenta una vista in sezione ingrandita del manufatto di figura 1 dopo una ulteriore fase di lavorazione con asportazione meccanica superficiale, ad esempio una levigatura e successiva lucidatura. figure 2 represents an enlarged sectional view of the article of figure 1 after a further processing step with mechanical surface removal, for example a smoothing and subsequent polishing.
Più in dettaglio il manufatto di materiale conglomerato viene ottenuto mediante il procedimento descritto qui di seguito nelle sue varie fasi. More in detail, the manufactured article of conglomerate material is obtained by means of the procedure described below in its various phases.
La prima fase prevede la preparazione di un impasto costituito da: The first phase involves the preparation of a mixture consisting of:
- granulati di materiale lapideo naturale quali il marmo, il granito, il quarzo, le sabbie silicee oppure materiali lapidei artificiali quali i materiali ceramici o quelli vetrosi; - granules of natural stone material such as marble, granite, quartz, siliceous sands or artificial stone materials such as ceramic or glass materials;
- un legante organico come ad esempio la resina poliestere, epossidica, acrilica o biolenica oppure un legante inorganico quale il cemento Portland; - an organic binder such as for example polyester, epoxy, acrylic or biolenic resin or an inorganic binder such as Portland cement;
- un filler in polvere sottile costituito ad es. da materiale siliceo oppure calcareo; - preferibilmente vengono aggiunti additivi per favorire la reazione d’indurimento del legante e di altri additivi pigmentanti; - a fine powder filler consisting of eg. from siliceous or calcareous material; - additives are preferably added to favor the hardening reaction of the binder and other pigmenting additives;
- granuli di materiale duro trasparente ricoperti con un rivestimento comprendente glitter. - granules of transparent hard material coated with a coating comprising glitter.
Il glitter può essere applicato ai granuli di materiale duro con varie tecniche facilmente immaginabili dal tecnico del ramo. Glitter can be applied to hard material granules with various techniques that are easily imagined by the person skilled in the art.
E’ stato trovato particolarmente vantaggioso che il glitter sia adeso alla superficie dei granuli per mezzo di un collante trasparente. Vantaggiosamente, il glitter impiegato può avere granulometria compresa fra 0,1 e 2,0 mm It has been found particularly advantageous for the glitter to adhere to the surface of the granules by means of a transparent glue. Advantageously, the glitter used can have a particle size of between 0.1 and 2.0 mm
La quantità di granulato à ̈ tale che la percentuale in volume rispetto al totale della resina e dei granulati stessi à ̈ compresa tra il 40% e il 60%, preferibilmente il 50%. La granulometria del granulato di materiale inerte à ̈ compresa tra 0,1 mm e 8 mm e preferibilmente tra 0,5 mm e 5 mm. The quantity of granulate is such that the percentage by volume with respect to the total of the resin and the granulates themselves is between 40% and 60%, preferably 50%. The granulometry of the granulate of inert material is between 0.1 mm and 8 mm and preferably between 0.5 mm and 5 mm.
La quantità dei granuli di materiale duro trasparente ricoperti con un rivestimento costituito da glitter dipende dall’effetto estetico desiderato; può ad esempio costituire una porzione del 1 – 20% dell’impasto. The quantity of transparent hard material granules covered with a glitter coating depends on the desired aesthetic effect; it can for example constitute a portion of 1 - 20% of the dough.
L’impasto viene reso omogeneo mediante un’operazione di miscelazione che viene eseguita all’interno di apposite mescolatrici. The mixture is made homogeneous by means of a mixing operation which is carried out inside special mixers.
Successivamente si passa alla distribuzione dell’impasto così preparato entro uno stampo. Subsequently, the mixture thus prepared is distributed in a mold.
Nella fase successiva à ̈ prevista la compattazione, ad esempio mediante vibrazione oppure vibrocompressione in un ambiente sottovuoto, ottenendo così un manufatto compattato. In the next phase the compaction is foreseen, for example by vibration or vibrocompression in a vacuum environment, thus obtaining a compacted product.
Infine, nell’ultima fase si procede all’indurimento del legante, che in questo modo ingloba in modo permanente i granuli di materiale inerte. L’indurimento può avvenire a caldo oppure a freddo, ossia a temperatura ambiente, in funzione della tipologia di legante. Finally, in the last phase, the hardening of the binder is carried out, which in this way permanently incorporates the granules of inert material. Hardening can take place hot or cold, ie at room temperature, depending on the type of binder.
Se il manufatto indurito à ̈ un blocco, esso viene segato in lastre. If the hardened artifact is a block, it is sawn into slabs.
In figura 1 à ̈ mostrata in sezione ingrandita una zona superficiale di un manufatto, indicato genericamente con 10, dopo l’indurimento, con all’interno granuli 11 ricoperti con uno strato di glitter 12 (i granuli 11 in figura 1 e 2 hanno schematicamente una forma sferica, però nella realtà normalmente hanno una conformazione irregolare e spigolosa). Un collante trasparente 13, se impiegato, può essere presente come strato intermedio. Figure 1 shows an enlarged section of a surface area of an artifact, indicated generically with 10, after hardening, with granules 11 inside covered with a layer of glitter 12 (the granules 11 in figure 1 and 2 they schematically have a spherical shape, but in reality they usually have an irregular and angular shape). A transparent adhesive 13, if used, can be present as an intermediate layer.
In figura 2 à ̈ mostrata la zona di manufatto dopo la successiva fase di lavorazione che prevede l’asportazione meccanica superficiale, per scoprire i granuli ed aprire “finestre†trasparenti 14 sulla loro superficie che à ̈ affacciata sulla faccia in vista 15 del manufatto. Tale asportazione meccanica può coincidere con una fase di calibratura e levigatura alla quale le lastre vengono sottoposte. Figure 2 shows the area of the product after the subsequent processing phase which involves the mechanical removal of the surface, to uncover the granules and open transparent â € œwindowsâ € 14 on their surface which faces the visible face 15 of the artifact. This mechanical removal can coincide with a calibration and polishing phase to which the slabs are subjected.
In questo modo la porzione di ciascun granulo affiorante che resta immersa sotto la faccia a vista riflette la luce, in quanto il glitter sulla sua superficie riflette la luce incidente che attraversa il granulo, producendo un effetto estetico particolarmente piacevole ed apprezzato. In this way, the portion of each emerging granule that remains immersed under the exposed face reflects the light, as the glitter on its surface reflects the incident light that passes through the granule, producing a particularly pleasant and appreciated aesthetic effect.
L’operazione di asportazione meccanica o levigatura della superficie del manufatto destinata a rimanere in vista può essere più o meno profonda a seconda dell’effetto ottico ricercato. The mechanical removal or smoothing operation of the surface of the product intended to remain in view can be more or less deep depending on the desired optical effect.
In particolare la levigatura, come mostrato in figura 2, asporta almeno una parte del granulo superficiale, fino ad ottenere sul granulo una superficie piana di ingresso ed emissione della luce riflessa che à ̈ perfettamente complanare con la restante superficie del manufatto. In particular, polishing, as shown in figure 2, removes at least a part of the surface granule, until a flat surface is obtained on the granule for the entry and emission of the reflected light which is perfectly coplanar with the remaining surface of the product.
Si comprende quindi la necessità che i granuli rivestiti con glitter debbano essere costituiti da materiale sufficientemente duro (ad esempi, di durezza sostanzialmente comparabile alla durezza della restante parte del manufatto) e sufficientemente trasparente. It is therefore understood that the granules coated with glitter must be made of a material that is sufficiently hard (for example, of a hardness substantially comparable to the hardness of the remaining part of the product) and sufficiently transparent.
Il manufatto può essere legato con resine, e quindi sottoposto a catalisi a temperature che possono arrivare anche a 140°C; pertanto i granuli rivestiti con glitter devono resistere ad una temperatura di almeno 160°C ed inoltre non devono essere aggredibili da solventi organici, tipo stirene, contenuti nella resina impiegata. I granuli da rivestire con glitter possono ad esempio essere costituiti da quarzo trasparente oppure vetro. The product can be bonded with resins, and then subjected to catalysis at temperatures that can even reach 140 ° C; therefore the granules coated with glitter must withstand a temperature of at least 160 ° C and also must not be attacked by organic solvents, such as styrene, contained in the resin used. The granules to be coated with glitter can for example consist of transparent quartz or glass.
La granulometria dei granuli, allo stesso modo della granulometria del granulato impiegato, Ã ̈ preferibilmente compresa tra 0,1 e 8 mm. The granulometry of the granules, in the same way as the granulometry of the granulate used, is preferably between 0.1 and 8 mm.
Inoltre il colore del rivestimento costituito da glitter può essere vario. Ad esempio per creare un effetto estetico spiccato il glitter impiegato può essere di color oro o argento così da ottenere dei granulati dorati o argentati tali da rendere il prodotto finito ancor più apprezzabile dalla clientela. In addition, the color of the glitter coating can be varied. For example, to create a strong aesthetic effect, the glitter used can be gold or silver in order to obtain golden or silver granules such as to make the finished product even more appreciated by customers.
E’ evidente poi che qualsiasi modifica o variante funzionalmente equivalente ricade nell’ambito di protezione della presente invenzione. It is then evident that any modification or functionally equivalent variant falls within the scope of protection of the present invention.
Ad esempio à ̈ possibile impiegare altri materiali da rivestire con glitter a condizione che siano sufficientemente duri e trasparenti e quindi, oltre al quarzo e al vetro, potrebbe essere possibile impiegare materiali quali le vetroceramiche, la fluorite, ecc. For example, it is possible to use other materials to be coated with glitter provided that they are sufficiently hard and transparent and therefore, in addition to quartz and glass, it could be possible to use materials such as glass ceramics, fluorite, etc.
I granuli possono anche essere di materiale semi trasparente perché colorato nella massa per fornire colorazione alla luce che li attraversa e viene riflessa dal glitter. I granuli possono avere forma geometrica irregolare o più o meno regolare. The granules can also be of semi-transparent material because colored in the mass to provide color to the light that passes through them and is reflected by the glitter. The granules can have an irregular or more or less regular geometric shape.
L’impiego di glitter fornisce, fra l’altro, una superficie riflettente irregolare che moltiplica i raggi luminosi riflessi verso l’esterno della superficie del manufatto e ne “randomizza†le direzioni. Ciò permette di ottenere un effetto luminoso molto efficace ed esteticamente innovativo e gradevole, rispetto ad esempio, alla realizzazione di un semplice rivestimento continuo e/o uniforme a specchio sulla superficie dei granuli. The use of glitter provides, among other things, an irregular reflecting surface that multiplies the light rays reflected towards the outside of the surface of the product and “randomizes” their directions. This allows to obtain a very effective and aesthetically innovative and pleasant lighting effect, compared, for example, to the creation of a simple continuous and / or uniform mirror coating on the surface of the granules.
L’operazione di asportazione meccanica può essere realizzata meno profonda, fino a diventare una semplice spazzolatura nel caso il legante sia particolarmente tenero e/o i granuli superficiali rimangono sporgenti dalla superficie dopo l’indurimento dell’impasto (ad esempio perché non viene eseguita o à ̈ ridotta la pressatura dell’impasto). The mechanical removal operation can be carried out less deeply, until it becomes a simple brushing if the binder is particularly soft and / or the surface granules remain protruding from the surface after the mixture has hardened (for example, why not the dough is pressed or reduced).
Questi granuli, dopo la spazzolatura, sono rivestiti dal glitter solo nella porzione immersa sotto la superficie del manufatto ed, essendo costituti da materiale trasparente, la luce incidente, che attraversa il granulo sporgente e viene riflessa dal glitter, produce un effetto estetico particolarmente piacevole. Inoltre, tale effetto si unisce ad una superficie irregolare del manufatto. These granules, after brushing, are coated with glitter only in the portion immersed under the surface of the product and, being made up of transparent material, the incident light, which passes through the protruding granule and is reflected by the glitter, produces a particularly pleasant aesthetic effect. Furthermore, this effect is combined with an irregular surface of the product.
