The present invention refers to a structural paint or clay plaster for interiors and exteriors, according to the classifying part of claim 1.

Campo tecnico Technical field

Il campo di applicazione della presente pittura strutturale o intonaco sono le pitture e/o intonaco che hanno una particolare influenza sul clima dell?abitazione ed ha effetti sulle superfici all?interno ed esterno dell?abitazione sulle quali vengono applicate. In particolare l?argilla presente nell?intonaco aiuta a regolare la presenza di umidit? nella stanza (nell?ambiente) per limitare la formazione di muffa e simile, per migliorare il comfort abitativo, l?isolamento acustico ed il riverbero, contribuire al risparmio energetico e la tutela dell?ambiente con un prodotto riciclabile e contribuire alla protezione passiva dal fuoco. The field of application of this structural paint or plaster are paints and/or plasters which have a particular influence on the climate of the house and have effects on the surfaces inside and outside the house on which they are applied. In particular, the clay present in the plaster helps regulate the presence of humidity in the room (in the environment) to limit the formation of mold and the like, to improve living comfort, sound insulation and reverberation, contribute to energy saving and environmental protection with a recyclable product and contribute to passive protection against fire.

Stato della tecnica State of the art

Sono noti una moltitudine di intonaci o pitture strutturali per interni a base di argilla. Per esempio la DE 1900784 pubblica un composto da sabbie fini e argille macinate alle quali viene aggiunto un legante a base di cellulosa. Inoltre sono noti intonaci o pitture strutturali sempre a base di argille, rispettivamente a base di silicati idrati di alluminio, chiamati anche ?pittura intera cruda? nella quale viene aggiunto come legante della cellulosa metilica, dell?amido vegetali o della gomma arabica. A multitude of clay-based interior structural plasters or paints are known. For example, DE 1900784 publishes a compound of fine sands and ground clays to which a cellulose-based binder is added. Furthermore, plasters or structural paints are also known based on clays, respectively based on hydrated aluminum silicates, also called ?whole raw paint? in which methyl cellulose, vegetable starch or arabic gum is added as a binder.

Dalla BZ2004000038 ? nota una pittura strutturale o intonaco composta/o da argilla macinata, da sabbie fini o farine di pietra ed eventualmente da fibre di cellulosa, applicabili a strati sottili come pittura o anche a strati pi? grossi come intonaco sulle pareti o sui soffitti di ambienti interni. Questa pittura o intonaco comprende vetro solubile (silicato di potassio o di sodio) e dell?acqua in quantit? minima necessaria per ottenere una consistenza densa fruibile con l?aggiunta di acqua immediatamente prima dell?applicazione del prodotto. From BZ2004000038 ? Do you know a structural paint or plaster composed of ground clay, fine sands or stone flour and possibly cellulose fibers, applicable in thin layers like paint or even in thicker layers? thick as plaster on the walls or ceilings of interior environments. This paint or plaster includes soluble glass (potassium or sodium silicate) and water in quantities minimum necessary to obtain a thick consistency that can be used by adding water immediately before applying the product.

Il prodotto descritto presenta alcune peculiarit?. In particolare non viene raggiunto un grado di bianco molto alto. Inoltre il prodotto applicato non ? sufficientemente resistente alla abrasione e allo stato asciutto non ? sufficientemente duro. Inoltre dopo l?asciugatura si possono formare crepe per il ridimensionamento dall?argilla. La pittura strutturale o intonaco descritto nella pubblicazione ? indicato per un impiego solo all?interno di edifici e non su superfici esterne. The product described has some peculiarities. In particular, a very high degree of whiteness is not achieved. Furthermore, the product applied is not ? sufficiently resistant to abrasion and in the dry state not ? hard enough. Also after drying, cracks can form due to scaling from the clay. The structural paint or plaster described in the publication ? indicated for use only inside buildings and not on external surfaces.

Breve descrizione dell?invenzione Brief description of the invention

Lo scopo della presente invenzione ? di ovviare ai problemi dello stato della tecnica e di realizzare una pittura strutturale o intonaco in argilla per interni ed esterni e un metodo per la realizzazione di detta pittura strutturale o intonaco. The purpose of the present invention ? to overcome the problems of the state of the art and to produce a structural paint or clay plaster for interiors and exteriors and a method for making said structural paint or plaster.

Questo scopo viene raggiunto da una pittura strutturale o intonaco comprendente argilla per interni ed esterni, secondo la parte caratterizzante della rivendicazione 1. This object is achieved by a structural paint or plaster comprising clay for interiors and exteriors, according to the characterizing part of claim 1.

Viene proposta una pittura strutturale o un intonaco composto --da argilla dal 10% al 50% peso, A structural paint or a compound plaster is proposed -- of clay from 10% to 50% by weight,

-pigmenti minerali, farina di pietra o sabbia selezionata dal 1% al 50% peso e - mineral pigments, stone flour or selected sand from 1% to 50% by weight e

-fra 1% a 15% peso silicato di potassio o di sodio. -between 1% and 15% by weight of potassium or sodium silicate.

Secondo l?invenzione l?argilla viene aggiunta in una prima forma come argilla naturale cio? caolino naturale e in una seconda forma in cui l?argilla viene trattata cio? come caolino calcinato. Per caolino calcinato si intende caolino che ha subito un trattamento termico. Questo significa che viene riscaldato brevemente a una temperatura superiore ai 600 ?C. Vantaggiosamente l?argilla che viene aggiunta ? composta da un terzo di caolino calcinato e due terzi di caolino naturale. According to the invention the clay is added in a first form as natural clay, i.e. natural kaolin and in a second form in which the clay is treated cio? as calcined kaolin. Calcined kaolin means kaolin that has undergone a heat treatment. This means that it is briefly heated above 600?C. Advantageously the clay that is added? composed of one third calcined kaolin and two thirds natural kaolin.

Questa combinazione (composizione) garantisce un?ottima combinazione fra durezza superficiale, resistenza ad abrasione ed evita la formazione di crepe nello strato di pittura strutturale o nell?intonaco perci? pu? essere utilizzata sia all?interno che all?esterno di un edificio. This combination (composition) guarantees an excellent combination of surface hardness, resistance to abrasion and prevents the formation of cracks in the structural paint layer or plaster, therefore can? be used both inside and outside a building.

Alla massa viene aggiunto fra il 30 e il 50% peso acqua soltanto se il prodotto viene fornito in uno stato pastoso. Between 30 and 50% by weight of water is added to the mass only if the product is supplied in a pasty state.

Dopo la miscelazione dell?impasto questo viene fatto riposare per almeno 48 ore. In questo modo la reattivit? della massa viene ridotta, perci? la massa e meno aggressiva e pi? uniforme. Questa reattivit? ? causata soprattutto dal silicato di potassio o di sodio. After mixing the dough, it is left to rest for at least 48 hours. In this way the reactivity? of the mass is reduced, therefore? the mass and less aggressive and more? uniform. This reactivity ? mainly caused by potassium or sodium silicate.

La massa cos? ottenuta pu? essere applicata anche a spessori spessi (grandi) sulla parete vale a dire anche fino a 30 mm poich? la combinazione fra caolino calcinato e caolino naturale contribuisce alla massa una migliore flessibilit? ed un minore ritiro e perci? si formano meno crepe nello strato di intonaco e/o pittura applicata. The mass what? obtained pu? also be applied to thick (large) thicknesses on the wall, i.e. even up to 30 mm since? the combination of calcined kaolin and natural kaolin contributes to the mass better flexibility? and a minor withdrawal and therefore? fewer cracks form in the applied plaster and/or paint layer.

Nella massa possono essere aggiunte piccole parti di polimeri acrilici o silossanici di nuova generazione. Questi sono a zero emissione di COV (per COV si intende componenti organici volatili), per il raggiungimento di un prodotto a zero emissioni di COV. Small parts of new generation acrylic or siloxane polymers can be added to the mass. These have zero VOC emissions (VOC means volatile organic components), to achieve a zero VOC emission product.

Come gi? precedentemente sottolineato la massa pu? essere venduta anche soltanto come impasto al quale viene aggiunto in una seconda fase l?acqua. Preferibilmente viene realizzato in forma pastosa in questo modo viene garantita una maggiore precisione nella miscela dell?impasto. In questo caso il riposo deve essere sempre effettuato dopo l?aggiunta dell?acqua e l?impasto per esempio realizzato cos? dal pittore e/o muratore viene lasciato riposare preferibilmente per almeno 48 ore e poi impiegato per pitturare o applicare l?intonaco nell?edificio, sia sulla superficie interna che sulla superficie interna, per uniformare l?impasto. Questo ? particolarmente vantaggioso perch? la pittura strutturale o intonaco descritta/o nella presente invenzione viene preferibilmente utilizzato sia all?interno di un edificio che all?esterno. How already? previously underlined the mass pu? also be sold only as a mixture to which water is added in a second phase. It is preferably made in pasty form, in this way greater precision in the mixture of the dough is guaranteed. In this case, the rest must always be carried out after the addition of water and the dough, for example, made like this. by the painter and/or bricklayer it is left to rest preferably for at least 48 hours and then used to paint or apply the plaster in the building, both on the internal surface and on the internal surface, to uniform the mixture. This ? particularly advantageous why? the structural paint or plaster described in the present invention is preferably used both inside a building and outside.

Inoltre viene rivendicato un metodo per la realizzazione di una pittura strutturale o un intonaco in cui viene mescolato Also claimed is a method of making a structural paint or plaster into which it is mixed

argilla dal 10% al 50% peso, di cui fra il 5% al 25% caolino naturale e fra il 5% al 25% caolino calcinato. clay from 10% to 50% by weight, of which between 5% and 25% natural kaolin and between 5% and 25% calcined kaolin.

1% al 10% peso pigmenti minerali, 1% to 10% weight mineral pigments,

dal 1% al 50% peso farina di pietra o sabbia selezionata e peso silicato di potassio o di sodio fra 1% a 15%. from 1% to 50% by weight of stone flour or selected sand and potassium or sodium silicate by weight between 1% and 15%.

Viene aggiunto fra il 30% al 50% in peso acqua e poi l?impasto viene lasciato riposare per almeno 48 ore prima dell?applicazione su una parete. Between 30% and 50% by weight of water is added and then the mix is left to rest for at least 48 hours before applying to a wall.

E? infine chiaro che alla pittura o all?intonaco fin qui descritta/o possono essere applicate aggiunte, modifiche o varianti ovvie per un tecnico del ramo senza per questo fuoriuscire dall?ambito di tutela fornito dalle rivendicazioni annesse. AND? finally, it is clear that the paint or plaster described up to now can be subject to additions, modifications or variations that are obvious to a person skilled in the art without thereby departing from the scope of protection provided by the appended claims.
