DESCRIZIONE DESCRIPTION
del Brevetto Italiano per Invenzione Industriale dal titolo: of the Italian Patent for Industrial Invention entitled:
“COMPOSIZIONE DI MALTA†⠀ œCOMPOSITION OF MALTAâ €
La presente invenzione riguarda una composizione di malta, il suo uso ed il relativo procedimento di produzione. The present invention relates to a mortar composition, its use and the related production process.
Più in particolare l’invenzione riguarda una composizione di malta ed il suo uso come riempifughe, particolarmente per pavimentazioni e rivestimenti di pareti mediante lastre o piastrelle ceramiche, pietre naturali o simili manufatti sostanzialmente lastriformi. More particularly, the invention relates to a composition of mortar and its use as a grout, particularly for flooring and wall cladding using ceramic slabs or tiles, natural stone or similar substantially plate-like products.
È noto rivestire le superfici dei pavimenti e/o delle pareti di un edificio o simile mediante la posa di pannelli di rivestimento, i più comuni dei quali sono notoriamente rappresentati da lastre o piastrelle ceramiche. It is known to cover the surfaces of the floors and / or walls of a building or the like by laying cladding panels, the most common of which are notoriously represented by ceramic slabs or tiles.
La posa delle lastre o piastrelle ceramiche prevede generalmente di stendere sulla superficie da rivestire uno strato di mastice o di apposito collante, e quindi di applicare le lastre o piastrelle ceramiche su detto strato, accostandole le une alle altre in modo da realizzare un rivestimento continuo. The laying of ceramic slabs or tiles generally involves spreading a layer of mastic or special glue on the surface to be coated, and then applying the ceramic slabs or tiles on said layer, placing them side by side so as to create a continuous coating.
Nonostante le lastre o piastrelle ceramiche siano reciprocamente ravvicinate, le stesse rimangono separate da fessure più o meno strette che sono note come fughe. Although the ceramic slabs or tiles are close to each other, they remain separated by more or less narrow cracks which are known as joints.
Tali fughe vengono successivamente riempite con un’apposita malta, ad esempio cementizia, formando tuttavia una sorta di reticolato che rimane visibile sul rivestimento finito. These joints are subsequently filled with a suitable mortar, for example cementitious, however forming a sort of cross-linked which remains visible on the finished covering.
L’aspetto del rivestimento finito rimane quindi caratterizzato dalla presenza di una pluralità di lastre o piastrelle ceramiche separate da un reticolato di fughe riempite di malta cementizia, la quale deve anch’essa possedere caratteristiche estetiche e funzionali durevoli nel tempo. The appearance of the finished covering therefore remains characterized by the presence of a plurality of ceramic slabs or tiles separated by a network of joints filled with cement mortar, which must also possess long-lasting aesthetic and functional characteristics.
Si riscontra sovente, tuttavia, che le fughe riempite di malta cementizia, la quale mantiene una certa porosità e, dunque, un certo grado di assorbimento d’acqua, sono sede di microrganismi, quali muffe, batteri o funghi che causano sulla malta cementizia sgradevoli colorazioni ed odori, macchie ed addirittura il deterioramento della stessa malta. It is often found, however, that the joints filled with cement mortar, which maintains a certain porosity and, therefore, a certain degree of water absorption, are home to microorganisms, such as mold, bacteria or fungi that cause on the cement mortar unpleasant colors and odors, stains and even the deterioration of the mortar itself.
Uno scopo della presente invenzione à ̈ quello di superare il menzionato inconveniente. An object of the present invention is to overcome the aforementioned drawback.
Ulteriore scopo dell’invenzione à ̈ quello di raggiungere tale obiettivo nell’ambito di una soluzione semplice, razionale e dal costo contenuto. A further purpose of the invention is to achieve this objective within the ambit of a simple, rational and low cost solution.
Tali scopi sono raggiunti dalle caratteristiche dell’invenzione riportate nelle rivendicazioni indipendenti. Le rivendicazioni dipendenti delineano aspetti preferiti e/o particolarmente vantaggiosi dell’invenzione. These objects are achieved by the characteristics of the invention reported in the independent claims. The dependent claims outline preferred and / or particularly advantageous aspects of the invention.
In particolare, l’invenzione rende disponibile una composizione di malta comprendente almeno un legante ed almeno un agente antibatterico inorganico atto ad essere disperso nel legante. In particular, the invention makes available a mortar composition comprising at least one binder and at least one inorganic antibacterial agent capable of being dispersed in the binder.
Il termine "comprendente" comprende anche "incluso" oltre a "costituito", ad es. una composizione "comprendente" X può essere costituita esclusivamente da X o può includere altre sostanze addizionali, ad esempio X+Y. The term "comprising" also includes "including" in addition to "consisting", e.g. a composition "comprising" X may consist solely of X or may include other additional substances, for example X + Y.
L’agente antibatterico à ̈ dunque disperso in tutta la massa del legante. The antibacterial agent is therefore dispersed throughout the mass of the binder.
L’azione dell’agente antibatterico à ̈ tale da inibire la crescita di batteri, funghi e muffe, inoltre, essendo di natura inorganica, non si usura nel tempo e mantiene il suo effetto antibatterico per tutta la durata della malta stessa. The action of the antibacterial agent is such as to inhibit the growth of bacteria, fungi and molds, moreover, being of an inorganic nature, it does not wear over time and maintains its antibacterial effect for the entire duration of the mortar itself.
Vantaggiosamente, la composizione di malta comprende anche almeno un materiale inerte, ad esempio che presenta una granulometria compresa tra 0,01 mm e 1 mm, il quale à ̈ atto ad essere anch’esso disperso nel legante, al fine di garantire alla malta una elevata resistenza meccanica e resistenza all’abrasione durevole nel tempo. Advantageously, the mortar composition also comprises at least one inert material, for example which has a particle size between 0.01 mm and 1 mm, which is also capable of being dispersed in the binder, in order to guarantee the mortar high mechanical strength and long-lasting abrasion resistance.
In una preferita forma di realizzazione, il legante à ̈ selezionato tra leganti idraulici, quali ad esempio cemento, calce idraulica, cemento alluminoso, materiali pozzolanici naturali, materiali pozzolanici artificiali e simili; il materiale inerte à ̈ selezionato tra carbonato di Calcio, Quarzo e sabbia silicea o una miscela dei tre suddetti componenti stessi. In a preferred embodiment, the binder is selected from hydraulic binders, such as for example cement, hydraulic lime, aluminous cement, natural pozzolanic materials, artificial pozzolanic materials and the like; the inert material is selected from calcium carbonate, quartz and silica sand or a mixture of the three aforementioned components.
Vantaggiosamente, l’agente antibatterico inorganico à ̈ costituito da ioni di Argento, preferibilmente stabilizzati su elementi di supporto di vetro o di argilla o simili, denominati “carrier†. Advantageously, the inorganic antibacterial agent consists of silver ions, preferably stabilized on glass or clay or similar support elements, called â € œcarrierâ €.
Gli ioni di Argento, come detto, sono tali da inibire la crescita dei microorganismi, quali i batteri, le muffe e i funghi, in quanto essi si legano alla struttura cellulare di tali microorganismi in modo da interagire con la sintesi enzimatica. In sostanza, impedendo la produzione energetica degli enzimi inibiscono la crescita dei microorganismi che non possono, quindi, riprodursi. The silver ions, as mentioned, are such as to inhibit the growth of microorganisms, such as bacteria, molds and fungi, as they bind to the cellular structure of these microorganisms in order to interact with enzymatic synthesis. Basically, by preventing the energy production of enzymes, they inhibit the growth of microorganisms that cannot, therefore, reproduce.
Inoltre, gli ioni di Argento intervengono nel meccanismo di duplicazione del DNA dei microorganismi favorendo la formazione di specie reattive all’ossigeno e, dunque, permette l’igiene della malta. Furthermore, the silver ions intervene in the DNA duplication mechanism of microorganisms, favoring the formation of reactive oxygen species and, therefore, allowing the hygiene of the mortar.
Preferibilmente, il legante, ad esempio il cemento, à ̈ presente in quantità compresa tra 20% e 60%, il materiale inerte à ̈ presente in quantità compresa tra 38% e 79.98%, mentre gli ioni di Argento sono presenti in quantità compresa tra 0.02% e 2%. Preferably, the binder, for example cement, is present in a quantity between 20% and 60%, the inert material is present in an amount between 38% and 79.98%, while the silver ions are present in quantities between 0.02% and 2%.
Tutti i valori indicati sono valori percentuali (%) in peso riferiti al peso totale della composizione. All the indicated values are percentage values (%) by weight referred to the total weight of the composition.
Vantaggiosamente, la composizione di malta comprende anche un additivo pozzolanico in quantità compresa tra 0% e 2%, il quale conferisce alla composizione migliore resistenza meccanica e stabilità cromatica. Advantageously, the mortar composition also comprises a pozzolanic additive in a quantity between 0% and 2%, which gives the composition better mechanical strength and chromatic stability.
Inoltre, l’additivo pozzolanico migliora e contribuisce ad eliminare le eventuali efflorescenze dovute alla presenza di calce libera nel cemento che costituisce il legante. Furthermore, the pozzolanic additive improves and helps to eliminate any efflorescence due to the presence of free lime in the cement which constitutes the binder.
Preferibilmente, come additivo pozzolanico sono utilizzabili microsilici o silice amorfa o metacaolini. Preferably, microsilic or amorphous silica or metakaolin can be used as the pozzolanic additive.
La composizione di malta secondo l’invenzione comprende, poi, un acceleratore di presa in quantità compresa tra 0% e 1,5%. The mortar composition according to the invention then comprises a setting accelerator in a quantity between 0% and 1.5%.
Tale acceleratore ha la funzione di abbreviare i tempi di essicazione della malta, una volta che essa sia posta in opera. This accelerator has the function of shortening the drying times of the mortar, once it has been applied.
Come acceleratore di presa può essere utilizzato, vantaggiosamente, alluminio solfato o calcio formiato. Aluminum sulphate or calcium formate can advantageously be used as a setting accelerator.
Inoltre, la composizione di malta può comprendere un fluidificante in quantità compresa tra 0% e 0,5%, tale da ridurre il rapporto acqua/legante nella malta, quando preparata per essere posta in opera, migliorandone la resistenza meccanica e la resistenza all’abrasione. Il fluidificante può essere un additivo a base di eteri policarbossilati o di melammina sulfonata. In addition, the mortar composition can include a fluidifying agent in a quantity between 0% and 0.5%, such as to reduce the water / binder ratio in the mortar, when prepared for application, improving its mechanical strength and resistance to wear. ™ abrasion. The fluidifier can be an additive based on polycarboxylated ethers or sulfonated melamine.
La composizione, secondo l’invenzione, può comprendere inoltre pigmenti coloranti in quantità compresa tra 0% e 5%. The composition, according to the invention, can also comprise coloring pigments in quantities ranging from 0% to 5%.
In aggiunta la composizione di malta comprende biossido di Titanio in quantità compresa tra 0% e 3%, il quale migliora la brillantezza e l’effetto cromatico della malta stessa. In addition, the composition of the mortar includes titanium dioxide in a quantity between 0% and 3%, which improves the brilliance and chromatic effect of the mortar itself.
La composizione, secondo l’invenzione, comprende poi un copolimero dispersibile in polvere in quantità compresa tra 0% e 3%, il quale permette di ridurre l’assorbimento d’acqua della malta dopo che la stessa à ̈ indurita, ovvero a seguito della messa in opera. The composition, according to the invention, also includes a dispersible copolymer in powder in a quantity between 0% and 3%, which allows to reduce the water absorption of the mortar after it has hardened, that is following implementation.
La composizione di malta, inoltre, può comprendere etere di cellulosa in quantità compresa tra 0% e 0,2% al fine di migliorare la reologia della malta stessa, la quale si traduce in una migliore applicabilità della malta durante la disposizione della stessa, ad esempio, all’interno delle fughe. Furthermore, the composition of the mortar can include cellulose ether in an amount between 0% and 0.2% in order to improve the rheology of the mortar itself, which translates into a better applicability of the mortar during its arrangement, for for example, inside the joints.
Vantaggiosamente, la composizione secondo l’invenzione può comprende re un idrorepellente in polvere in quantità compresa tra 0% e 1%, il quale permette di ridurre ulteriormente l’assorbimento d’acqua a seguito dell’indurimento della malta, una volta che questa sia posta in opera. Advantageously, the composition according to the invention can comprise a water repellent in powder in a quantity between 0% and 1%, which allows to further reduce the absorption of water following the hardening of the mortar, a once this is put in place.
ESEMPIO EXAMPLE
Un esempio di una malta di tipo cementizio à ̈ preparato a partire dalla seguente composizione: An example of a cement-based mortar is prepared starting from the following composition:
- cemento Portland (bianco o grigio) classe I 52.5 R presente in quantità pari al 30%; - Portland cement (white or gray) class I 52.5 R present in a quantity equal to 30%;
- quarzo con granulometria compresa tra 0,1 e 0,3 mm ed in quantità pari al 40% - quartz with a particle size between 0.1 and 0.3 mm and in a quantity equal to 40%
- carbonato di Calcio con granulometria pari a 40 µm ed in quantità pari al 25,5%; - Calcium carbonate with a particle size of 40 µm and in a quantity of 25.5%;
- silice amorfa in quantità pari allo 1%; - 1% amorphous silica;
- Calcio formiato in quantità pari allo 1%; - Calcium formate in a quantity equal to 1%;
- Melammina sulfonata in quantità pari allo 0,1%; - Melamine sulfonate in a quantity equal to 0.1%;
- pigmenti di ossido di Ferro in quantità pari allo 0.5%; - Iron oxide pigments in quantities equal to 0.5%;
- biossido di Titanio in quantità pari allo 1%; - Titanium dioxide in a quantity equal to 1%;
- una resina in polvere a base di copolimero Vinil acetato/etilene in quantità pari allo 0,5%; - a resin in powder form based on vinyl acetate / ethylene copolymer in a quantity equal to 0.5%;
- Idrossietilcellulosa in quantità pari allo 0,03%; - Hydroxyethylcellulose in an amount equal to 0.03%;
- Silano in quantità pari allo 0,2%; - Silane in a quantity equal to 0.2%;
- ioni d’Argento stabilizzati su carrier, ad esempio su elementi di supporto in vetro, in quantità pari allo 0,15%. - Silver ions stabilized on carriers, for example on glass support elements, in quantities equal to 0.15%.
Un altro aspetto della presente invenzione à ̈ l'impiego di una composizione di malta come riempifughe di pavimenti e rivestimenti di pareti. Another aspect of the present invention is the use of a mortar composition as a grout filler for floors and wall coverings.
Un aspetto non meno importante della invenzione à ̈ un procedimento per la preparazione di una composizione dell'invenzione che comprende le fasi di dosare la quantità in peso, ad esempio mediante bilance, delle polveri dei vari componenti sopra elencati secondo, ad esempio, la ricetta sopra esposta nell’esempio. A no less important aspect of the invention is a process for the preparation of a composition of the invention which comprises the steps of dosing the quantity by weight, for example by means of scales, of the powders of the various components listed above according to, for example, the recipe shown above in the example.
Le polveri così dosate vengono poi caricate in un mescolatore a vomeri o a pale per la miscelazione a secco delle polveri stesse. The dosed powders are then loaded into a ploughshare or paddle mixer for dry mixing of the powders themselves.
La miscelazione può durare alcuni secondi, al termine della miscelazione la composizione à ̈ pronta per essere resa disponibile ad una macchina insaccatrice per poter essere poi posta in opportuni sacchi. Per mettere in opera la malta con funzione antibatterica, infine, à ̈ sufficiente bagnare la malta stessa con un’opportuna quantità d’acqua e mescolarla, quando la pasta così ottenuta avrà raggiunto la consistenza desiderata si procede stendendola in modo che essa penetri all’interno della fuga da riempire, in modo da riempirla completamente. The mixing can last a few seconds, at the end of the mixing the composition is ready to be made available to a bagging machine to be then placed in suitable bags. Finally, to apply the mortar with an antibacterial function, it is sufficient to wet the mortar itself with an appropriate amount of water and mix it, when the paste thus obtained has reached the desired consistency, proceed by spreading it so that it penetrate inside the joint to be filled, in order to fill it completely.
Per stendere la malta à ̈ utilizzabile una spatola in gomma o altro utensile di tipo noto. A rubber spatula or other known type of tool can be used to spread the mortar.
Una volta stesa la malta, quando questa inizia ad indurire e rapprendersi, si procede con la pulizia delle fughe. Ad esempio, mediante una spugna umida si passa sulle fughe stesse in modo da dare alla malta in esse presente una conformazione sostanzialmente omogenea. Infine si procede lasciando asciugare la malta e rimuovendo le eventuali sbavature sulla superficie delle piastrelle o lastre ceramiche. Dopo poche ore gli ioni di Argento sono già attivi presentando la suddetta azione antibatterica. Once the mortar has been spread, when it begins to harden and congeal, the joints are cleaned. For example, using a damp sponge, one passes over the joints themselves so as to give the mortar present therein a substantially homogeneous conformation. Finally, proceed by letting the mortar dry and removing any burrs on the surface of the ceramic tiles or slabs. After a few hours the Silver ions are already active presenting the aforementioned antibacterial action.
Si intende che l’invenzione non à ̈ limitata agli esempi sopradescritti e che varianti e perfezionamenti potranno esservi apportati senza uscire dall’ambito delle seguenti rivendicazioni. It is understood that the invention is not limited to the examples described above and that variations and improvements may be made without departing from the scope of the following claims.
