"Procedimento per la decorazione della superficie di un film di polimero fluorurato" "Process for decorating the surface of a fluorinated polymer film"
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce ad un procedimento per la decorazione della superficie di un substrato costituito da un film di polimero fluorurato, in particolare di ETFE (etilene-tetrafluoroetilene). The present invention relates to a process for decorating the surface of a substrate consisting of a fluorinated polymer film, in particular of ETFE (ethylene-tetrafluoroethylene).
L’ETFE à ̈ un polimero termoplastico che presenta elevata resistenza meccanica ed alla corrosione in un’ampia gamma di temperature. L’ETFE ha una temperatura di fusione di 260°C, eccellenti proprietà chimiche, dielettriche, alta resistenza all’attacco chimico, ed à ̈ inalterabile alla radiazione solare ed ultravioletta. La sua formula chimica di struttura à ̈ la seguente: ETFE is a thermoplastic polymer which has high mechanical and corrosion resistance in a wide range of temperatures. ETFE has a melting temperature of 260 ° C, excellent chemical and dielectric properties, high resistance to chemical attack, and is unalterable to solar and ultraviolet radiation. Its structural chemical formula is as follows:
Uno strato di ETFE ha un peso pari solo al 60/70% di quello di una lastra di vetro di uguale volume. Inoltre, poiché esso consente l’uso di soluzioni applicative più razionali, il peso unitario al m<2>di una copertura di ETFE può essere pari solo a circa il 5% di quello di una analoga copertura formata da vetro e relativa struttura portante. Tale materiale à ̈ inoltre autopulente grazie alla sua superficie antiaderente, ritardante la fiamma e non combustibile, nonché riciclabile a fine utilizzo. L’ETFE ha un’ampia gamma di temperature di servizio (da -200 a 150 °C), bassa infiammabilità , eccellenti proprietà elettriche e meccaniche, ottima resistenza ai solventi e ai prodotti chimici, una resistenza estremamente elevata agli agenti atmosferici esterni, un’alta trasmissione della luce nel visibile e UV, proprietà di antiaderenza, ottima resistenza allo strappo, bassa permeabilità e buona resistenza alle radiazioni. A layer of ETFE has a weight equal to only 60/70% of that of a glass sheet of the same volume. Furthermore, since it allows the use of more rational application solutions, the unit weight per m <2> of an ETFE covering can only be equal to about 5% of that of a similar covering made of glass and relative structure. carrier. This material is also self-cleaning thanks to its non-stick, flame retardant and non-combustible surface, as well as recyclable at the end of use. ETFE has a wide range of service temperatures (from -200 to 150 ° C), low flammability, excellent electrical and mechanical properties, excellent resistance to solvents and chemicals, extremely high resistance to external atmospheric agents , a high transmission of light in the visible and UV, non-stick properties, excellent tear resistance, low permeability and good resistance to radiation.
Esso à ̈ tipicamente applicato in membrane architettoniche, film, rivestimenti, isolamenti di cavi elettrici, tubi, in particolare tubi flessibili per carburanti, e valvole. It is typically applied in architectural membranes, films, coatings, electrical cable insulations, pipes, especially fuel hoses, and valves.
L’ETFE à ̈ processabile con la tecnologia dell’estrusione in testa piana, tramite la quale si possono ottenere film in larghezze variabili da 500 a 2000 mm e spessori variabili da 13 a 300 µm, con tolleranze di spessore non superiori al 4%. ETFE can be processed with the flat head extrusion technology, through which it is possible to obtain films in variable widths from 500 to 2000 mm and thicknesses from 13 to 300 µm, with thickness tolerances not exceeding 4 %.
La materia prima in forma di granuli viene alimentata da dosatori gravimetrici alla bocca di alimentazione di un estrusore, costituito da un cilindro termostatato entro cui una vite di apposito profilo induce, tramite rotazione, la fusione dei granuli per attrito, omogeneizzandone la massa fusa ed aumentandone la pressione necessaria per farla avanzare attraverso un filtro che ha lo scopo di separare le particelle estranee e non ancora completamente fuse. The raw material in the form of granules is fed by gravimetric dosers to the feed mouth of an extruder, consisting of a thermostated cylinder within which a screw with a special profile induces, by rotation, the fusion of the granules by friction, homogenizing the melted mass and increasing it the pressure necessary to advance it through a filter which has the purpose of separating foreign particles and not yet completely melted.
A valle del filtro, la massa fusa entra in una pompa ad ingranaggi che ha lo scopo di generare una portata continua esente da fluttuazioni di pressione, che consente la distribuzione omogenea del flusso di materiale fuso all’interno di condotti della testa di estrusione, evitando pertanto percorsi preferenziali che comporterebbero disuniformità di spessori. Downstream of the filter, the molten mass enters a gear pump which has the purpose of generating a continuous flow rate free from pressure fluctuations, which allows the homogeneous distribution of the flow of molten material inside the ducts of the extrusion head, thus avoiding preferential paths that would lead to uneven thicknesses.
La testa à ̈ caratterizzata da una filiera (fessura di uscita del materiale fuso) lineare, la cui apertura può essere variata manualmente e grossolanamente a seconda dello spessore di film che si vuole ottenere. La regolazione fine e accurata dell’apertura à ̈ realizzata durante l’estrusione da un dispositivo che rileva in tempo reale e continuo lo spessore del film e, in funzione dell’errore rilevato rispetto ad un set-point prefissato, invia dei segnali di correzione ad una serie di bulloni termici posizionati in corrispondenza della filiera, i quali per effetto di dilatazione termica modificano puntualmente l’apertura della filiera ovvero della fessura d’uscita del polimero fuso. The head is characterized by a linear die (exit slot of the melted material), whose opening can be varied manually and roughly according to the thickness of the film to be obtained. The fine and accurate adjustment of the opening is carried out during extrusion by a device that detects the thickness of the film in real time and continuously and, depending on the error detected with respect to a predetermined set-point, sends correction signals to a series of thermal bolts positioned in correspondence with the die, which due to the effect of thermal expansion punctually modify the opening of the die or the exit slot of the molten polymer.
Una volta uscito dalla filiera, il film di materiale plastico viene appoggiato su rulli di raffreddamento a temperatura via via decrescente, così da essere raffreddato e stabilizzato nella sua caratteristica dimensionale. Once released from the die, the plastic film is placed on cooling rollers at a gradually decreasing temperature, so as to be cooled and stabilized in its dimensional characteristics.
I film così prodotti sono di materiale chimicamente inerte e quindi insensibili all’aggressione chimica. Trasmettono la luce solare in percentuale superiore al 90% e sono leggeri, avendo una densità di 1,72:1,78 kg/dm<3>. Le caratteristiche di resistenza meccanica consentono applicazioni atte a sopportare carichi e sollecitazioni esterne. The films thus produced are made of chemically inert material and therefore insensitive to chemical aggression. They transmit sunlight in a percentage greater than 90% and are light, having a density of 1.72: 1.78 kg / dm <3>. The mechanical resistance characteristics allow applications suitable to withstand external loads and stresses.
In ambito architettonico, l’ETFE offre ai progettisti, grazie alle sue peculiari proprietà , notevoli opportunità per lo sviluppo di moderne soluzioni che integrano leggerezza, durata, design ed ecologia. In the architectural field, ETFE offers designers, thanks to its peculiar properties, significant opportunities for the development of modern solutions that integrate lightness, durability, design and ecology.
Un film di ETFE può anche essere colorato, mediante additivazione in massa con opportuni pigmenti (master batch) in forma di granuli, che vengono alimentati all’estrusore in opportuna percentuale rispetto al polimero base. Inoltre, il film finale può mantenere una certa traslucentezza, variando il colore della luce trasmessa e ampliando le possibilità estetiche e progettuali. An ETFE film can also be colored, by mass addition with suitable pigments (master batch) in the form of granules, which are fed to the extruder in a suitable percentage with respect to the base polymer. Furthermore, the final film can maintain a certain translucency, varying the color of the transmitted light and expanding the aesthetic and design possibilities.
Attualmente, poche aziende al mondo stampano la superficie di film di ETFE, operazione che deve essere comunque preceduta da un trattamento corona per l’attivazione superficiale che renda la superficie bagnabile da inchiostri o vernici. Currently, few companies in the world print the surface of ETFE film, an operation which must in any case be preceded by a corona treatment for surface activation that makes the surface wettable by inks or paints.
I risultati finora ottenuti sono decorazioni a motivi monocromatici argentati, bianchi, neri o grigi, molto semplici e ripetitivi, quali pallini o svariate forme geometriche, in positivo o in negativo e di diverse dimensioni. Tali decorazioni sono garantite per una resistenza di 5 anni alla radiazione solare. The results obtained so far are decorations with silver, white, black or gray monochromatic motifs, very simple and repetitive, such as dots or various geometric shapes, in positive or negative and of different sizes. These decorations are guaranteed for 5 years resistance to solar radiation.
Generalmente, questi film serigrafati sono utilizzati come superficie esterna e/o interna di cuscini gonfiati con aria, che fungono da elemento di copertura allo scopo di limitare l’irraggiamento solare all’interno delle strutture, riflettendo verso l’esterno la radiazione luminosa e solare. Generally, these screen-printed films are used as the external and / or internal surface of air-inflated cushions, which act as a covering element in order to limit solar radiation inside the structures, reflecting the radiation outwards. bright and sunny.
Sono note soluzioni che permettono di regolare la quantità di irraggiamento che penetra nella struttura semplicemente allontanando o avvicinando due film serigrafati a motivi complementari: non si avrà irraggiamento quando i due film sono perfettamente a contatto, si avrà invece l’irraggiamento massimo quando i due film sono alla massima distanza possibile. Il movimento relativo dei film all’interno del cuscino à ̈ regolato dalla pressione dell’aria nei diversi comparti di quest’ultimo. Solutions are known which allow to regulate the amount of irradiation that penetrates into the structure simply by moving away or nearing two films screen-printed with complementary motifs: there will be no irradiation when the two films are perfectly in contact, instead there will be maximum irradiation when the two films are at the maximum distance possible. The relative movement of the films inside the cushion is regulated by the air pressure in the various compartments of the latter.
Più film di ETFE possono essere uniti tra loro esclusivamente mediante saldatura termica. Di conseguenza, la presenza di deposizioni di alluminio sulla superficie limita sensibilmente la possibilità di saldare tra loro due film, richiedendo di fatto la “raschiatura†dei motivi grafici dalle superfici in corrispondenza esatta delle linee di saldatura. Several ETFE films can be joined together exclusively by thermal welding. Consequently, the presence of aluminum deposition on the surface significantly limits the possibility of welding two films together, requiring in fact the â € œwrappingâ € of the graphic motifs from the surfaces in exact correspondence of the welding lines.
Le decorazioni finora realizzate non sono inoltre in grado di resistere all’azione di agenti esterni per tutta la durata di vita prevista per il film associato. Pertanto, esse debbono essere “protette†, in particolare utilizzando specifici accorgimenti realizzativi atti ad evitarne il dissolvimento. The decorations made so far are also not able to resist the action of external agents for the entire duration of life foreseen for the associated film. Therefore, they must be â € œprotectedâ €, in particular by using specific construction devices aimed at avoiding their dissolution.

Esempio Example
Su di un film di cellulosa dello spessore nominale di 20 µm viene stampato un motivo decorativo tridimensionale attraverso una tecnica rotocalco che prevede l’utilizzo di una miscela di resine organiche della classe delle cellulose. All’interno delle resine organiche sono contenuti pigmenti della classe dei dispersi per sublicromia. A three-dimensional decorative motif is printed on a cellulose film with a nominal thickness of 20 µm using a rotogravure technique which involves the use of a mixture of organic resins of the cellulose class. Inside the organic resins are contained pigments of the class of dispersed by sublichromy.
Il film di cellulosa decorato viene poi messo a contatto con un film di ETFE e portato alla temperatura di 220°C utilizzando una calandra riscaldata con olio diatermico. Al termine dell’intimo contatto della durata approssimativa di 25 secondi, il film di ETFE ha assorbito i pigmenti della classe dei dispersi e mostra un aspetto decorato, dovuto al trasferimento sulla sua superficie del motivo decorativo. The decorated cellulose film is then put in contact with an ETFE film and brought to a temperature of 220 ° C using a calender heated with diathermic oil. At the end of the intimate contact lasting approximately 25 seconds, the ETFE film has absorbed the pigments of the dispersed class and shows a decorated appearance, due to the transfer of the decorative motif onto its surface.
