TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
La presente invenzione si riferisce ad una pasta a bassa densità di rivestimento superficiale per intonaco. The present invention relates to a low density surface coating paste for plaster.
L'impiego di aerogel silicati nella produzione di materiali termoisolanti, generalmente in forma di pannelli, è ampiamente noto allo stato della tecnica. The use of silicate airgels in the production of heat-insulating materials, generally in the form of panels, is widely known in the state of the art.
Infatti, l'impiego di una percentuale di aerogel nella composizione dei materiali suddetti permette il conseguimento di differenti vantaggi, quali l'ottenimento di un apprezzabile livello di isolamento termico, e garantisce al contempo un peso specifico più contenuto rispetto ai tradizionali materiali termoisolanti. In fact, the use of a percentage of airgel in the composition of the aforesaid materials allows the achievement of different advantages, such as the achievement of an appreciable level of thermal insulation, and at the same time guarantees a lower specific weight than traditional heat-insulating materials.
Il documento n. CN101468907 A rende nota una pasta di isolamento termico comprendente, in percentuale di peso: Document no. CN101468907 A discloses a thermal insulation paste comprising, in percentage by weight:
- nano-aerogel silicato 20 ~ 50%; - silicate nano-aerogel 20 ~ 50%;
- micro sfere di materiale organico ad anello chiuso 0 3 0%; - micro spheres of organic material in closed ring 0 3 0%;
- perlite espansa 7 ~ 15%; - expanded perlite 7 ~ 15%;
- bentonite 0 ~ 1%; - bentonite 0 ~ 1%;
- agente penetrante 2 ~ 6%; - penetrating agent 2 ~ 6%;
- adesivo 10 ~ 20%; - adhesive 10 ~ 20%;
- fibra di silicato di calcio 3 ~ 6%; - calcium silicate fiber 3 ~ 6%;
- fibra di silicato di magnesio e alluminio 0 ~ 5%; - fibra di silicato di alluminio 0 ~ 5%; - 0 ~ 5% aluminum and magnesium silicate fiber; - 0 ~ 5% aluminum silicate fiber;
- acqua 0 ~ 40%; - water 0 ~ 40%;
- sostanze ignifughe 0,1 ~ 2%; - flame retardant substances 0.1 ~ 2%;
- sostanze coloranti 3 ~ 7%. - coloring substances 3 ~ 7%.
Sebbene detta pasta sia in grado di permettere il conseguimento di un buon livello di isolamento termico, tuttavia, per ottenere del pari un risultato ignifugo, necessita l'aggiunta di una o più componenti aventi detta proprietà. Inoltre, detta pasta termoisolante nota prevede una composizione piuttosto complessa, con quanto ne consegue in termini di difficoltà e costi di produzione della stessa. Although said paste is capable of allowing the achievement of a good level of thermal insulation, however, in order to obtain a fireproof result, it requires the addition of one or more components having said properties. Furthermore, said known thermal insulating paste provides a rather complex composition, with what follows in terms of difficulty and production costs thereof.
In aggiunta, vista la composizione di detta pasta termoisolante nota, è evidente come il peso specifico della stessa tenda ad essere relativamente elevato, con inevitabili ricadute sul peso complessivo del prodotto finale in seguito a posa in opera, nonché evidente pregiudizio in termini di efficienza nell'isolamento termico. In addition, given the composition of said known thermal insulating paste, it is evident that the specific weight of the same tends to be relatively high, with inevitable repercussions on the overall weight of the final product following installation, as well as evident damage in terms of efficiency in the process. 'thermal insulation.
Dal documento WO2010128294 Al è noto un metodo per la produzione di un materiale solido a bassa densità derivante dal riso, comprendente un primo strato solido comprendente gel derivato da sottoprodotto della lavorazione del riso, un secondo strato solido comprendente gel derivato da riso allo stato grezzo macinato, detto primo e detto secondo strato essendo successivamente sottoposti a laminazione in modo da ottenere detto materiale solido in forma sostanzialmente di pannello. From document WO2010128294 A1 a method is known for the production of a low density solid material deriving from rice, comprising a first solid layer comprising gel derived from by-product of rice processing, a second solid layer comprising gel derived from ground raw rice , said first and said second layer being subsequently subjected to lamination so as to obtain said solid material substantially in the form of a panel.
Detto materiale solido noto presenta effettivamente un peso specifico relativamente contenuto, nonché un apprezzabile livello di isolamento termico. Said known solid material actually has a relatively low specific weight, as well as an appreciable level of thermal insulation.
Tuttavia, detto processo di laminazione può anzitutto rivelarsi dannoso per l'aerogel, dal momento che quest'ultimo è inevitabilmente sottoposto ad elevate pressioni di formatura. However, said rolling process can first of all prove to be harmful for the airgel, since the latter is inevitably subjected to high forming pressures.
Inoltre, detti due aerogel risultano fra loro separati, costituendo ciascuno uno rispettivo di detti due strati del pannello, senza conseguire l'ottenimento di alcun effetto sinergico. Furthermore, said two airgels are separated from each other, each constituting a respective one of said two layers of the panel, without achieving any synergistic effect.
In aggiunta, presentandosi detto materiale noto sostanzialmente a guisa di un pannello a doppio strato laminato, ne derivano inevitabili inconvenienti in sede di posa in opera, la quale risulta decisamente poco agevole. In addition, since said known material is substantially in the manner of a double-layer laminated panel, there are inevitable drawbacks during installation, which is decidedly not easy.
Peraltro, detto materiale solido laminato noto non consente di deporre uno strato sottile di finitura superficiale direttamente sull'intonaco. Moreover, said known laminated solid material does not allow to lay a thin surface finishing layer directly on the plaster.
D'altra parte, il processo produttivo di detto materiale solido noto, sebbene più economico rispetto a quelli noti per l'ottenimento dei comuni aerogel silicati, necessita comunque di una lavorazione piuttosto complessa. On the other hand, the production process of said known solid material, although cheaper than those known for obtaining common silicate airgels, still requires a rather complex processing.
La presente invenzione, partendo dalla nozione dei suesposti inconvenienti, intende porvi rimedio. The present invention, starting from the notion of the aforementioned drawbacks, intends to remedy them.

Un altro scopo della presente invenzione è di provvedere una pasta a bassa densità di rivestimento superficiale come specificato, che presenti una composizione semplice, di facile produzione, lavorazione e posa in opera. Another object of the present invention is to provide a low density surface coating paste as specified, which has a simple composition, easy to manufacture, process and apply.
Un altro scopo ancora della presente invenzione è di provvedere una pasta a bassa densità di rivestimento superficiale come detto, che presenti un peso specifico relativamente contenuto, e che comporti un apprezzabile livello di leggerezza complessiva del prodotto, successivamente alla posa in opera. Yet another object of the present invention is to provide a low-density surface coating paste as mentioned, which has a relatively low specific weight, and which entails an appreciable level of overall lightness of the product, after installation.
E' altresì scopo della presente invenzione provvedere una pasta a bassa densità di rivestimento superficiale come sopra indicato, in cui i relativi materiali costitutivi non siano esposti ad eventuali rischi di danneggiamento in corso di produzione.
