Description

DESCRIZIONE DESCRIPTION

L’oggetto del presente trovato è costituito da un procedimento per la realizzazione di un prodotto bicomponente particolarmente studiato per la finitura murale e dal prodotto ottenuto mediante tale procedimento. The object of the present invention consists of a process for making a two-component product particularly designed for wall finishing and the product obtained by means of this process.

L’impiego di finiture murali ben realizzate permette, nel campo edilizio, la realizzazione di pareti presentanti un ottimo aspetto estetico ed un’elevata durata nel tempo grazie alle proprie capacità di ancoraggio. The use of well-made wall finishes allows, in the construction field, the creation of walls with an excellent aesthetic appearance and high durability thanks to their anchoring capabilities.

Sono noti nella tecnica alcuni procedimenti che consentono la realizzazione di diversi prodotti idonei alla finitura murale ad uno o più componenti, realizzati con o senza l'aggiunta di acqua. Some processes are known in the art which allow the production of different products suitable for wall finishing with one or more components, made with or without the addition of water.

Questi, pur rispondendo al problema tecnico esposto, presentano i seguenti svantaggi. These, while responding to the technical problem described, have the following disadvantages.

I prodotti realizzati a secco richiedono nel momento dell’impiego un costo di manodopera aggiuntivo, poiché vanno preparati all’uso mediante aggiunta di acqua, preparazione che viene effettuata manualmente dallo stesso personale specializzato prima della posa in opera. Dry-made products require an additional labor cost at the time of use, since they must be prepared for use by adding water, a preparation that is carried out manually by the same specialized personnel before installation.

I tempi globali di realizzazione sono quindi più elevati ed incidono sui costi finali sopportati dall’utente . The overall construction times are therefore higher and affect the final costs borne by the user.

Un ulteriore svantaggio dei prodotti a secco noti, consiste nel tempo limitato di stoccaggio in magazzino, per la perdita delle caratteristiche chimico fisiche dei prodotti medesimi, le quali al massimo restano costanti per un anno dal momento della fabbricazione. A further disadvantage of known dry products consists in the limited storage time in the warehouse, due to the loss of the chemical-physical characteristics of the products themselves, which remain constant for a maximum of one year from the moment of manufacture.

I prodotti pronti all’uso realizzati mediante procedimenti comprendenti l’aggiunta di acqua richiedono per supporti diversi mani di fondo diverse, con ovvio aumento dei tempi di realizzazione e dei costi relativi. Ready-to-use products made using processes including the addition of water require different primers for different substrates, with an obvious increase in production times and related costs.

Molti di essi inoltre, pur resistendo molto bene nel tempo, presentano un aspetto finale scadente, che si distacca notevolmente dal marmorino classico. Moreover, many of them, while resisting very well over time, have a poor final appearance, which is noticeably detached from the classic marmorino.

Infine i componenti impiegati nei procedimenti noti, prevedono spesso la presenza di cemento e di prodotti di sintesi, per cui si discostano notevolmente dalle recenti esigenze della bioarchitettura per quanto riguarda i rivestimenti murali. Finally, the components used in known processes often provide for the presence of cement and synthetic products, so they differ considerably from the recent requirements of bio-architecture as regards wall coverings.

Scopo della presente invenzione è quello di ovviare agli inconvenienti propri dello stato anteriore della tecnica. The object of the present invention is to obviate the drawbacks of the prior state of the art.

L'invenzione ha quindi come oggetto un procedimento per la realizzazione di un prodotto bicomponente particolarmente studiato per la finitura murale ed il prodotto ottenuto mediante tale procedimento, dove tale prodotto si presenta pronto all’uso, stabile per lunghissimo tempo, facilmente impiegabile, di alto pregio estetico e realizzabile con un procedimento che impiega macchine note nella tecnica e materiali altamente biocompatibili. The invention therefore has as its object a process for the production of a two-component product particularly studied for wall finishing and the product obtained by means of this process, where this product is ready to use, stable for a very long time, easily usable, of high aesthetic value and achievable with a process that uses machines known in the art and highly biocompatible materials.

Brevemente, secondo l'invenzione, viene realizzato un procedimento per la realizzazione di un prodotto bicomponente particolarmente studiato per la finitura murale comprendente un componente di base ed un componente di finitura, dove il componente di base è ottenuto attraverso una o più fasi in cui vengono mescolati alcuni elementi quali almeno idrossido di calcio, latte, caolino, materiale inerte e colla, mentre il componente di finitura è ottenuto attraverso una o più fasi in cui vengono mescolati alcuni elementi quali almeno idrossido di calcio, latte, carbonato di calcio e talco. Briefly, according to the invention, a process is carried out for the production of a two-component product particularly studied for wall finishing comprising a base component and a finishing component, where the base component is obtained through one or more phases in which they are some elements such as at least calcium hydroxide, milk, kaolin, inert material and glue are mixed, while the finishing component is obtained through one or more phases in which some elements such as at least calcium hydroxide, milk, calcium carbonate and talc are mixed.

Mediante tale procedimento si ottiene un particolare prodotto bicomponente particolarmente studiato per la finitura murale, dove il componente di base comprende almeno idrossido di calcio, latte, caolino, materiale inerte e colla, ed il componente di finitura comprende almeno idrossido di calcio, latte carbonato di calcio e talco. By means of this process, a particular two-component product is obtained, particularly studied for wall finishing, where the basic component includes at least calcium hydroxide, milk, kaolin, inert material and glue, and the finishing component includes at least calcium hydroxide, milk carbonate calcium and talc.

Il procedimento per la realizzazione di un prodotto bicomponente particolarmente studiato per la finitura murale, secondo l’invenzione, è caratterizzato dal fatto di presentare le caratteristiche descritte nella rivendicazione 1. The process for making a two-component product particularly designed for wall finishing, according to the invention, is characterized by the fact that it presents the characteristics described in claim 1.

Con il procedimento in oggetto e con il prodotto da questo ottenuto secondo l’invenzione, si hanno i seguenti vantaggi. With the process in question and with the product obtained from it according to the invention, the following advantages are obtained.

È possibile operare direttamente su qualunque tipo di supporto come cartongesso, intonaco tradizionale, lisciature in gesso, idropitture esistenti ben ancorate, senza applicare mani di fondo diverse, con evidente risparmio di tempi e costi. It is possible to work directly on any type of substrate such as plasterboard, traditional plaster, gypsum smoothing, existing well-anchored water-based paints, without applying different primers, with obvious savings in time and costs.

I prodotti in oggetto, permettono di effettuare le fasi di lavorazione su superfici assorbenti mediante modalità fresco su fresco, tenendo conto della capacità di assorbimento del supporto, il lavoro di posa in opera diviene quindi più rapido e meno faticoso. The products in question allow the processing steps to be carried out on absorbent surfaces using fresh on fresh mode, taking into account the absorption capacity of the substrate, the installation work therefore becomes faster and less tiring.

L'aspetto finale al termine della lavorazione è di alto pregio estetico, essendo quello del marmorino classico, mentre i tempi di lavorazione rispetto allo stesso marmorino classico vengono ridotti fino al 50%. The final appearance at the end of the processing is of high aesthetic value, being that of the classic marmorino, while the processing times compared to the same classic marmorino are reduced by up to 50%.

Un ulteriore vantaggio consiste nell’alta qualità dei materiali impiegati, che rispecchiano perfettamente le moderne esigenze di biocompatibilità per quanto riguarda i rivestimenti murali. A further advantage consists in the high quality of the materials used, which perfectly reflect the modern requirements of biocompatibility with regard to wall coverings.

Infine l'uso diversificato del componente di base e del componente di finitura permette di ottenere un'ampia gamma di finiture quali ad esempio intonachino, calce rasata, patinatura a calce, rilievi. Finally, the diversified use of the base component and the finishing component allows to obtain a wide range of finishes such as plaster, smoothed lime, lime coating, reliefs.

Ulteriori caratteristiche, vantaggi e particolarità esecutive del procedimento per la realizzazione di un prodotto bicomponente particolarmente studiato per la finitura murale e del prodotto ottenuto mediante tale procedimento, risulteranno meglio compresi mediante l’ausilio della seguente descrizione con riferimento ai disegni allegati, nei quali sono illustrate, a titolo indicativo, ma non limitativo, alcune forme preferite di realizzazione.

Con particolare riferimento ai simboli numerici delle varie figure dei disegni allegati, il presente procedimento per la realizzazione di un prodotto bicomponente particolarmente studiato per la finitura murale, prevede la realizzazione di un componente di base 10 e di un componente di finitura 20. With particular reference to the numerical symbols of the various figures of the attached drawings, the present process for the production of a two-component product particularly designed for wall finishing, provides for the production of a base component 10 and a finishing component 20.

Il componente di base 10 viene realizzato secondo le fasi che seguono mescolando opportunamente materiale inerte, idrossido di calcio, caolino, colla e latte. The base component 10 is made according to the following steps by suitably mixing inert material, calcium hydroxide, kaolin, glue and milk.

Più precisamente una fase 1 prevede che una quantità di idrossido di calcio compresa tra 15 ed il 45% in peso, preferibilmente del 30% del componente di base 10 con funzioni di legante e fungicida, venga mescolata con un’impastatrice meccanica nota nella tecnica ad una quantità di latte compresa tra lo 0,3 ed il 15% in peso della base 10, preferibilmente del 2%. More precisely, a step 1 provides that an amount of calcium hydroxide comprised between 15 and 45% by weight, preferably 30% of the base component 10 acting as a binder and fungicide, is mixed with a mechanical mixer known in the art. a quantity of milk comprised between 0.3 and 15% by weight of the base 10, preferably 2%.

Il latte impiegato è preferibilmente parzialmente scremato al 50% ed intero per la metà rimanente, anche se può essere costituito da una miscela qualsiasi di latte intero, parzialmente scremato e scremato. Preferibilmente inoltre l’idrossido di calcio o calce spenta deve opportunamente trascorrere un periodo di stagionatura di almeno sei mesi prima di essere impiegato per il procedimento in oggetto. The milk used is preferably 50% partially skimmed and whole for the remaining half, even if it can consist of any mixture of whole, partially skimmed and skimmed milk. Furthermore, calcium hydroxide or slaked lime must preferably spend a seasoning period of at least six months before being used for the process in question.

Una fase 2 del procedimento secondo l'invenzione, prevede che una quantità di materiale inerte compresa tra il 45 ed il 80% in peso della base 10, preferibilmente del 62,5% venga mescolata in modo omogeneo ad una quantità di colla compresa tra lo 0,1 e Γ 1% in peso della base 10, preferibilmente dello 0,4%, ed a una quantità di caolino compresa tra il 1 e l’9% in peso della stessa base 10, preferibilmente del 5%. A phase 2 of the process according to the invention provides that a quantity of inert material comprised between 45 and 80% by weight of the base 10, preferably 62.5%, is homogeneously mixed with a quantity of glue comprised between 0.1 and Γ 1% by weight of the base 10, preferably 0.4%, and to a quantity of kaolin comprised between 1 and 9% by weight of the same base 10, preferably 5%.

Il materiale inerte comprende preferibilmente polvere di marmo di qualsiasi tipo con granulometria compresa tra 0,05 ed 2 mm, preferìbilmente di 0,5 mm, mentre la colla impiegata è preferibilmente a base di metilcellulosa, pur essendo impiegabili colle acrìliche o composte da carbossimetilcellulosa. The inert material preferably comprises marble powder of any type with a particle size between 0.05 and 2 mm, preferably 0.5 mm, while the glue used is preferably based on methylcellulose, although acrylic glues or glues composed of carboxymethylcellulose can be used.

In una successiva fase 3, vengono mescolati insieme gli impasti ottenuti mediante le fasi 1 e 2, ottenendo infine la base 10. In a subsequent phase 3, the mixtures obtained by means of phases 1 and 2 are mixed together, finally obtaining the base 10.

Si osservi inoltre, che in ciascuna delle fasi sopra illustrate, è possibile l'aggiunta di acqua per rendere maggiormente omogeneo l'impasto risultante. It should also be noted that in each of the steps illustrated above, it is possible to add water to make the resulting mixture more homogeneous.

In particolare quando dovesse essere impiegato dell’idrossido di calcio poco stagionato, può essere evitata l'aggiunta di acqua, mentre se questo è particolarmente secco a causa di un elevato periodo di stagionatura, è possibile aggiungere fino a 400 g d’acqua per ogni Kg del componente di base 10 ottenuto come illustrato in precedenza, dove tale aggiunta può essere fatta in ogni momento delle fasi 1 ,2,3. In particular, when slightly seasoned calcium hydroxide is used, the addition of water can be avoided, while if this is particularly dry due to a long seasoning period, it is possible to add up to 400 g of water for each Kg of the base component 10 obtained as previously illustrated, where this addition can be made at any time of steps 1, 2,3.

Una volta prodotta, la base 10 viene richiusa in contenitori sigillati dove vantaggiosamente, mantiene inalterate le proprie caratteristiche chimico fisiche per circa dieci anni. Once produced, the base 10 is closed in sealed containers where it advantageously maintains its chemical-physical characteristics unaltered for about ten years.

Alternativamente è possibile ottenere la base 10 attraverso un mescolamento diverso delle varie sostanze componenti la base 10, mescolamento che può anche avvenire in un’unica fase 4 attraverso l'unione contemporanea o con un ordine diverso da quanto illustrato precedentemente delle medesime sostanze 5 quali materiale inerte, idrossido di calcio, caolino, colla e latte, purché vengano rispettate le proporzioni precedentemente illustrate. Alternatively, it is possible to obtain the base 10 through a different mixing of the various substances making up the base 10, mixing which can also take place in a single phase 4 through the simultaneous union or with a different order from that illustrated above of the same substances 5 as material. inert, calcium hydroxide, kaolin, glue and milk, provided that the proportions previously illustrated are respected.

Anche in tal caso, l’acqua può essere aggiunta nelle medesime quantità e modalità per rendere la base 10 maggiormente omogenea. Even in this case, the water can be added in the same quantities and methods to make the base 10 more homogeneous.

Il componente di finitura 20 viene realizzato secondo le fasi che seguono mescolando opportunamente idrossido di calcio, carbonato di calcio, talco e latte. The finishing component 20 is made according to the following steps by suitably mixing calcium hydroxide, calcium carbonate, talc and milk.

Più precisamente, una fase 11 prevede che una quantità di idrossido di calcio compresa tra il 45 ed il 90% in peso del componente di finitura 20, preferibilmente del 67,5% venga mescolata con una quantità di latte compresa tra lo 0,3 ed il 15% in peso del medesimo componente di finitura 20, preferibilmente del 2,5%, mediante un’impastatrice meccanica nota nella tecnica. More precisely, a step 11 provides that an amount of calcium hydroxide comprised between 45 and 90% by weight of the finishing component 20, preferably 67.5%, is mixed with a quantity of milk comprised between 0.3 and 15% by weight of the same finishing component 20, preferably 2.5%, by means of a mechanical mixer known in the art.

Una successiva fase 12 prevede che alla miscela ottenuta venga aggiunta una quantità di carbonato di calcio compresa tra 8 e 40% in peso del componente di finitura 20, preferibilmente del 22,5% ed una volta ottenuto un composto omogeneo, una fase 13 prevede l'aggiunta di una quantità di talco compresa tra il 2 ed il 15% in peso del medesimo componente 20, preferibilmente del 7,5%. A subsequent phase 12 provides that an amount of calcium carbonate comprised between 8 and 40% by weight of the finishing component 20, preferably of 22.5%, is added to the obtained mixture, and once a homogeneous compound has been obtained, a phase 13 provides the addition of a quantity of talc comprised between 2 and 15% by weight of the same component 20, preferably 7.5%.

Vantaggiosamente è inoltre possibile aggiungere all’impasto ottenuto una piccola quantità di colla fino ail’1% in peso del composto precedentemente ottenuto. Advantageously, it is also possible to add a small amount of glue up to 1% by weight of the previously obtained compound to the mixture obtained.

Più particolarmente tale aggiunta può essere vantaggiosamente effettuata prima della fase 12 mischiando opportunamente la colla con il carbonato di calcio, prima di incorporare quest’ultimo nell'impasto ottenuto al termine della fase 11. More particularly, this addition can be advantageously carried out before phase 12 by suitably mixing the glue with calcium carbonate, before incorporating the latter into the mixture obtained at the end of phase 11.

Un ulteriore variante consiste in una fase 14 dove al componente di finitura 20 ottenuto come illustrato in precedenza, viene aggiunta una quantità di olio da 0,5% fino al 5% in peso del componente 20 medesimo. A further variant consists of a step 14 where an amount of oil ranging from 0.5% to 5% by weight of the component 20 itself is added to the finishing component 20 obtained as illustrated above.

Più precisamente, l’olio può essere olio di lino cotto od un olio commercialmente noto come olio duro, presentante anch'esso ottime caratteristiche di biocompatibilità, inoltre sono possibili anche miscele di entrambi in qualsiasi proporzione. More precisely, the oil can be cooked linseed oil or an oil commercially known as hard oil, which also has excellent characteristics of biocompatibility, and mixtures of both in any proportion are also possible.

Si osservi infine che olio e colla possono essere anche presenti entrambi nel componente di finitura 20. Finally, it should be noted that oil and glue may also be present both in the finishing component 20.

Anche per la realizzazione del componente di finitura 20, può essere aggiunta acqua durante una qualsiasi delle fasi 11,12,13,14, o in tutte e quattro le suddette fasi. Also for the production of the finishing component 20, water can be added during any one of the phases 11,12,13,14, or in all four of the aforementioned phases.

In particolare l’acqua non viene aggiunta qualora l’idrossido di calcio abbia subito una stagionatura ridotta, mentre è possibile aggiungere fino ad un Kg d’acqua per ogni Kg di componente di finitura 20 ottenuto come illustrato in precedenza, nel caso che l’idrossido di calcio impiegato risulti particolarmente secco. In particular, water is not added if the calcium hydroxide has undergone a reduced seasoning, while it is possible to add up to one kg of water for each kg of finishing component 20 obtained as illustrated above, in the event that the used calcium hydroxide is particularly dry.

Anche per la realizzazione del componente di finitura 20, si può alternativamente procedere mediante un unica fase 15 in cui gli elementi 16 costituenti il suddetto componente di finitura 20 quali idrossido di calcio, carbonato di calcio, talco, latte, ed eventualmente colla ed olio, vengono contemporaneamente mescolati tra loro o comunque aggregati con un ordine diverso da quanto prima illustrato, rispettando però le proporzioni precedentemente indicate. Also for the realization of the finishing component 20, one can alternatively proceed by means of a single step 15 in which the elements 16 constituting the aforementioned finishing component 20 such as calcium hydroxide, calcium carbonate, talc, milk, and possibly glue and oil, they are simultaneously mixed with each other or in any case aggregated in a different order from that illustrated above, respecting however the proportions previously indicated.

Anche in tal caso, l'acqua può essere aggiunta nelle medesime quantità e modalità prima illustrate per rendere il componente di finitura 20 maggiormente omogeneo. Also in this case, the water can be added in the same quantities and methods described above to make the finishing component 20 more homogeneous.

Il componente di finitura 20, comunque realizzato, viene poi mantenuto sigillato in opportuni contenitori fino al momento dell’impiego, mantenendo così inalterate le proprie caratteristiche chimico fisiche per una decina d’anni. The finishing component 20, however manufactured, is then kept sealed in suitable containers until the moment of use, thus maintaining its chemical-physical characteristics unaltered for about ten years.

Ovviamente, tutti i particolari realizzativi potranno essere sostituiti da altri elementi tecnicamente equivalenti: di conseguenza, le macchine ed i materiali impiegati, nonché le dimensioni e le forme contingenti potranno essere opportunamente variati, a seconda delle esigenze. Obviously, all the construction details can be replaced by other technically equivalent elements: consequently, the machines and materials used, as well as the contingent shapes and dimensions, can be suitably varied, according to requirements.

Il prodotto ottenuto mediante il procedimento in oggetto si presenta all’operatore già pronto all'uso, contenuto nei contenitori sigillati prima illustrati. The product obtained by the process in question is presented to the operator ready for use, contained in the sealed containers illustrated above.

Viene quindi applicata una prima mano del componente di base 10, mediante un frattazzo di acciaio, lasciando asciugare compietamente il prodotto, per poi applicare in modo uniforme una seconda mano. A first coat of the base component 10 is then applied by means of a steel trowel, allowing the product to dry completely, and then a second coat is applied uniformly.

Successivamente si procede immediatamente con una lisciatura mediante un frattazzo in plastica, attraverso movimenti rotatori, in modo da rendere la superficie planare estremamente compatta. Then proceed immediately with a smoothing using a plastic trowel, through rotary movements, in order to make the planar surface extremely compact.

Ai termine di una completa asciugatura, si applicano due mani del prodotto di finitura 20, compattando molto la superficie, ed avendo l’accortezza di non applicare troppo materiale per non perdere l’effetto di trasparenza. At the end of a complete drying, two coats of the finishing product 20 are applied, compacting the surface a lot, and taking care not to apply too much material so as not to lose the transparency effect.

Quindi prima che il prodotto asciughi completamente si lucida mediante spatole o frattazzi in plastica con bordi levigati per non danneggiare quanto fatto precedentemente, sono inoltre vantaggiosamente impiegabili anche tamponi di nylon molto sottile. Therefore, before the product dries completely, it is polished by means of spatulas or plastic trowels with smooth edges in order not to damage what has been done previously, also very thin nylon pads can be advantageously used.

Infine in caso di supporti assorbenti non è necessaria la compietà asciugatura tra le fasi di lavorazione. Finally, in the case of absorbent substrates, complete drying is not necessary between the processing phases.
