La presente invenzione si riferisce ad un materiale cartaceo (carta/cartoncino) ad effetto-ruvido sabbia e al relativo procedimento di fabbricazione; più precisamente, il materiale cartaceo dell’invenzione, grazie ad un impasto appositamente studiato e ad uno specifico trattamento superficiale, perde al tatto le caratteristiche tipiche dei materiali cartacei e si caratterizza per un effetto al tatto simile alla sabbia. The present invention refers to a paper material (paper / cardboard) with a rough sand effect and to the relative manufacturing process; more precisely, the paper material of the invention, thanks to a specially studied mixture and a specific surface treatment, loses to the touch the typical characteristics of paper materials and is characterized by a touch effect similar to sand.
Nel settore cartario à ̈ costante la ricerca di nuovi tipi di carte aventi aspetti e/o finiture particolari, soprattutto destinate all’imballaggio, al confezionamento, alla realizzazione di materiale illustrativo, alla stampa di qualità , eccetera. In the paper sector there is a constant search for new types of paper with particular aspects and / or finishes, especially intended for packaging, wrapping, the creation of illustrative material, quality printing, and so on.
Non di rado, però, l’ottenimento di effetti particolari pregiudica altre caratteristiche della carta, ad esempio la stampabilità . Not infrequently, however, the achievement of particular effects jeopardizes other characteristics of the paper, such as printability.
È uno scopo della presente invenzione quello di fornire un materiale cartaceo che abbia un effetto al tatto differente dai tradizionali materiali cartacei e sia al contempo stampabile con elevata qualità di stampa. It is an object of the present invention to provide a paper material which has a different touch effect from traditional paper materials and is at the same time printable with high printing quality.
La presente invenzione à ̈ dunque relativa ad un materiale cartaceo e al relativo procedimento di fabbricazione come definiti nelle annesse rivendicazioni 1 e, rispettivamente, 8. The present invention therefore relates to a paper material and the related manufacturing process as defined in the attached claims 1 and 8, respectively.

L’invenzione fornisce dunque un materiale cartaceo (carta/cartoncino) ad effetto sabbia il quale, grazie ad un impasto appositamente studiato e ad uno specifico trattamento superficiale, perde al tatto le caratteristiche tipiche dei materiali cartacei e si caratterizza per un effetto al tatto simile alla sabbia, avendo una finitura superficiale ruvida tipica di una superficie coperta di sabbia fine. The invention therefore provides a paper material (paper / cardboard) with a sand effect which, thanks to a specially designed mixture and a specific surface treatment, loses the typical characteristics of paper materials to the touch and is characterized by a touch effect similar to sand, having a rough surface finish typical of a surface covered with fine sand.
Il materiale cartaceo dell’invenzione risulta inoltre perfettamente stampabile con elevata qualità di stampa e consente di ottenere effetti grafici particolari, difficili da ottenere con tradizionali carte patinate. The paper material of the invention is also perfectly printable with high printing quality and allows to obtain particular graphic effects, difficult to obtain with traditional coated papers.
In dettaglio, il materiale cartaceo del trovato comprende un supporto base che à ̈ formato da una miscela di fibre cellulosiche e contiene almeno una sostanza polimerica, atta a conferire alla miscela di fibre resistenza meccanica (a secco e ad umido), e una carica inorganica, atta a conferire al materiale buone caratteristiche di macchinabilità . In detail, the paper material of the invention comprises a base support which is formed by a mixture of cellulosic fibers and contains at least one polymeric substance, capable of giving the mixture of fibers mechanical strength (dry and wet), and an inorganic filler , able to give the material good machinability characteristics.
Il supporto base ha almeno una superficie (faccia) trattata con almeno un collante superficiale ed una patina aventi particolari componenti, in modo tale che il materiale cartaceo, per effetto combinato della composizione del supporto base e del trattamento superficiale, abbia un effetto al tatto simile alla sabbia. Chiaramente, entrambe le facce del supporto base possono essere trattate allo stesso modo. The base support has at least one surface (face) treated with at least one surface glue and a patina having particular components, so that the paper material, due to the combined effect of the composition of the base support and the surface treatment, has a similar touch effect. to the sand. Clearly, both faces of the base support can be treated equally.
Preferibilmente, la sostanza polimerica inclusa nel supporto base comprende una o più resine a base di colofonia e/o di alchil chetene dimero e/o di acido acetil succinico e/o di epocloridrina, e/o amidi modificati; e la carica inorganica à ̈ una carica minerale comprendente una o più sostanze scelte nel gruppo costituito da carbonati, caolini, talco, loro miscele. Preferably, the polymeric substance included in the base support comprises one or more resins based on rosin and / or alkyl ketene dimer and / or acetyl succinic acid and / or epochlorhydrin, and / or modified starches; and the inorganic filler is a mineral filler comprising one or more substances selected from the group consisting of carbonates, kaolins, talc, their mixtures.
Il collante superficiale à ̈ per esempio un collante a base di amido e/o di alcol polivinilico e/o di polimeri acrilici, poliuretanici e/o stirolo-butadienici. The surface adhesive is, for example, an adhesive based on starch and / or polyvinyl alcohol and / or acrylic, polyurethane and / or styrene-butadiene polymers.
Inoltre, il materiale cartaceo dell’invenzione à ̈ provvisto di una patina, applicata sulla superficie trattata (chiaramente, il materiale cartaceo può avere entrambe le superfici trattate e provviste di patina). In addition, the paper material of the invention is provided with a patina, applied to the treated surface (clearly, the paper material can have both surfaces treated and coated with patina).
In particolare, la patina à ̈ formata da uno o più polimeri leganti (per esempio polimeri a base poliuretanica e/o siliconica, e/o polimeri acrilici, stirolo-butadienici, polivinil-acetati, alcol polivinilico, e similari) e/o cere, in miscela con pigmenti, per esempio pigmenti a struttura lamellare o piatta, come ad esempio carbonato di calcio precipitato (PCC), caolini per patinatura, caolini calcinati e/o lamellari, in abbinamento a pigmenti a base di silicati di calcio aventi diversa granulometria e grado di bianco superiore a circa 85 (secondo la norma DIN 5033). In particular, the patina is formed by one or more binding polymers (for example polyurethane and / or silicone based polymers, and / or acrylic, styrene-butadiene polymers, polyvinyl acetates, polyvinyl alcohol, and the like) and / or waxes , mixed with pigments, for example pigments with a lamellar or flat structure, such as precipitated calcium carbonate (PCC), kaolins for coating, calcined and / or lamellar kaolins, in combination with pigments based on calcium silicates having different granulometry and whiteness higher than about 85 (according to DIN 5033).
Proprio questi pigmenti a base di silicati di calcio, aventi preferibilente particelle di granulometria varia (cioà ̈ dimensioni diverse) e un particolare grado di bianco sono di particolare importanza per il risultato desiderato. Precisely these pigments based on calcium silicates, preferably having particles of various granulometry (ie different sizes) and a particular degree of whiteness, are of particular importance for the desired result.
In particolare, i pigmenti comprendono wallastonite (silicato di calcio di formula CaSiO3). In particular, the pigments include wallastonite (calcium silicate of the formula CaSiO3).
Preferibilmente, la quantità di polimero per faccia à ̈ preferibilmente compresa tra 5% e 100% rispetto ai pigmenti; la grammatura del materiale cartaceo à ̈ compresa tra circa 90 e circa 350 g/mq; la quantità di patina spalmata su ciascuna faccia à ̈ compresa tra circa 5 e circa 20 g/mq. Preferably, the amount of polymer per face is preferably comprised between 5% and 100% with respect to the pigments; the weight of the paper material is between about 90 and about 350 g / m2; the amount of patina spread on each face is between about 5 and about 20 g / m2.
La patina può essere colorata e/o spalmata su un supporto base colorato; preferibilmente, si usano colori in pasta e pigmenti organici o inorganici. The patina can be colored and / or spread on a colored base support; preferably, paste colors and organic or inorganic pigments are used.
Il materiale cartaceo appena descritto viene realizzato, in accordo con un ulteriore aspetto della presente invenzione, con il metodo seguente. The paper material just described is made, in accordance with a further aspect of the present invention, with the following method.
Viene realizzato dapprima il supporto base, con tecnica di formazione della carta sostanzialmente nota, per esempio su una macchina continua per la fabbricazione della carta. The basic support is first made, with a substantially known paper forming technique, for example on a paper making machine.
In sostanza, si predispone un impasto acquoso di fibre di cellulosa e contenente la sostanza polimerica (resine a base di colofonia e/o di alchil chetene dimero e/o di acido acetil succinico e/o di epocloridrina, e/o amidi modificati) e la carica inorganica (carbonati, caolini, talco, eccetera). Basically, an aqueous slurry of cellulose fibers is prepared and contains the polymeric substance (resins based on rosin and / or alkyl ketene dimer and / or acetyl succinic acid and / or epochlorhydrin, and / or modified starches) and the inorganic charge (carbonates, kaolins, talc, etc.).
Successivamente, si rimuove acqua dall’impasto per formare il supporto base del materiale cartaceo. Subsequently, water is removed from the mixture to form the basic support of the paper material.
Segue una fase di trattamento superficiale di una o entrambe le facce del supporto base con una soluzione acquosa di collante superficiale, per esempio composto da una soluzione acquosa di amido al 10% in peso, e/o collante acrilico al 5% in peso, o collanti similari come descritto in precedenza (collanti a base di alcol polivinilico e/o di polimeri acrilici, poliuretanici e/o stirolo-butadienici). Il trattamento con il collante superficiale serve anche a conferire al materiale cartaceo una corretta penetrazione all’acqua, indispensabile per la successiva fase di patinatura. This is followed by a step of surface treatment of one or both faces of the base support with an aqueous solution of surface glue, for example composed of an aqueous solution of starch at 10% by weight, and / or acrylic glue at 5% by weight, or similar adhesives as described above (adhesives based on polyvinyl alcohol and / or acrylic, polyurethane and / or styrene-butadiene polymers). The treatment with the surface glue also serves to give the paper material correct water penetration, which is essential for the subsequent coating phase.
Il metodo comprende poi, dopo il trattamento superficiale con collante, una fase di lisciatura del supporto base, in cui il supporto base à ̈ lisciato fino a valori di liscio Bendsten ISO 2494 inferiore a circa 50 ml/min e preferibilmente inferiore a circa 30 ml/min e indicativamente intorno a 20 ml/min. The method then includes, after the surface treatment with glue, a smoothing phase of the base support, in which the base support is smoothed up to Bendsten ISO 2494 smooth values of less than about 50 ml / min and preferably less than about 30 ml. / min and roughly around 20 ml / min.
Successivamente, si applica la patina precedentemente descritta. Subsequently, the previously described patina is applied.
Preferibilmente, l’applicazione della patina avviene tramite spalmatura eseguita con macchina a lama d’aria o con lama lisciante ed à ̈ seguita da una fase di asciugatura della patina, condotta in forno ad infrarossi e/o ad aria calda a temperatura compresa tra circa 100°C e circa 180°C e con tempo di permanenza in forno compreso fra 0,5 e 4 minuti. Preferably, the application of the patina takes place by spreading performed with an air knife or with a smoothing blade and is followed by a drying phase of the patina, carried out in an infrared and / or hot air oven at a temperature included between about 100 ° C and about 180 ° C and with a residence time in the oven between 0.5 and 4 minutes.
Infine, il metodo comprende una fase di trattamento meccanico della superficie provvista della patina, in particolare una fase di lisciatura e/o una fase di goffratura. Finally, the method comprises a step of mechanical treatment of the surface provided with the patina, in particular a smoothing step and / or an embossing step.
Resta poi inteso che al materiale cartaceo e al relativo metodo di fabbricazione qui descritti ed illustrati possono essere apportate modifiche e varianti che non escono dall’ambito dell’invenzione come definito nelle annesse rivendicazioni. It is then understood that modifications and variations may be made to the paper material and the relative manufacturing method described and illustrated herein which do not depart from the scope of the invention as defined in the attached claims.
