Si pu? in particolare fare a meno dell'impiego di un bagno di incisione chimica per l'opacizzazione di superi lei. In this way, with the transfer of the pattern drawn from the sheet to a laminate in synthetic material, with a chipboard panel or similar? It is possible to obtain an inverted surface structure. Can you? in particular, to dispense with the use of a chemical etching bath for the opacification of surfaces.
Descrizione del trovato Description of the finding
L'invenzione si riferisce ad un procedimento per produrre superfici strutturate su lamiere, cilindri, nastri senza fine o similari, in acciaio o di metalli non ferrosi, da impiegare come controstampo per fa strutturazione superficiale di laminati in materia artificiale pannelli truciolari e similari; laddove in un primo momento la lamiera, il cilindro ovvero il nastro senza fine o similare, successivamente mediante un inchiostro da stampa vengono stampati con un modello di disegno, dopo di che, Il tutto viene sottoposto ad un bagno di trattamento e successivamente viene tolto l'inchiostro da stampa . The invention relates to a process for producing structured surfaces on sheets, cylinders, endless strips or the like, in steel or non-ferrous metals, to be used as a counter-mold for surface structuring of laminates made of artificial material, chipboard panels and the like; where at first the sheet metal, the cylinder or the endless ribbon or similar, subsequently by means of a printing ink are printed with a drawing model, after which, the whole is subjected to a treatment bath and subsequently removed the printing ink.
Per produrre superfici strutturate su lamiere, cilindri, nastri senza fine o similari, finora, partendo da una superficie nuda, completamente lucida, era usuale stampigliarla con un modello di disegno corrispondente alla successiva struttura .superficiale delle piastre da produrre. Mediante il successivo trattamento in un bagno di incisione chimica, vengono in particolare irruvidite le superfici prive di inchiostro da stampa, ossia, dette superfici vengono opacizzate, cosicch? dopo aver tolto l'inchiostro in un'ultima fase di lavorazione e punti opacizzati, sono situati ribassati nella sezione trasversale della lamiera, mentre le superfici nude, preventivamente coperte da inchistro da' stampa, risultano in risalto. Se una lamiera prodotta con questa nota modalit? viene impiegata come controstampo per una riproduzione su piastra, ad esempio di laminato di materiale sintetico, per panelli truciolari o similari, allora le parti opacizzate, ribassate del controstampo compaiono come superfici in risalto nella riproduzione sulla piastra, mentre i punti licidi in rilievo compaiono nella forma di intagli ribassati . To produce structured surfaces on sheets, cylinders, endless strips or the like, until now, starting from a bare, completely glossy surface, it was usual to stamp it with a design pattern corresponding to the subsequent surface structure of the plates to be produced. By means of the subsequent treatment in a chemical etching bath, the surfaces without printing ink are roughened in particular, that is, said surfaces are opaque, so that the surfaces are roughened. after having removed the ink in a last phase of processing and the opaque points, are located lowered in the cross section of the sheet, while the bare surfaces, previously covered by printing ink, stand out. If a sheet produced with this known modality? it is used as a counter-mold for a reproduction on a plate, for example of laminate of synthetic material, for chipboard panels or similar, then the opaque, lowered parts of the counter-mold appear as surfaces in relief in the reproduction on the plate, while the licidi points in relief appear in the form of lowered notches.
Con questa modalit? operativa si ? dimostrato svantaggioso il fatto, che le produzioni su piastra, nelle quali le superfici irruvidite appaiono in risalto, sono assai suscettibili nei confronti del l'insudiciamento e difficili da pulire. Impiegando tali riproduzioni su piastra, ad esempio come rivestimento interno a piastrelle o tessere, I punti opacizzati costituiscono facili superfici di attacco per la polvere ed il sudicium?, che non vengono tolti con la pulizia, ma penetrano ancora pi? a fondo nelle superfici opacizzate. Ci? influenza negativamente l'estetica. With this mode? operational yes? It has been shown to be disadvantageous that the productions on plate, in which the roughened surfaces appear in relief, are very susceptible to fouling and difficult to clean. By using these reproductions on the plate, for example as an internal coating on tiles or tesserae, the opaque points constitute easy attack surfaces for dust and dirt, which are not removed by cleaning, but penetrate even more? thoroughly into matted surfaces. There? negatively affects aesthetics.
Un ulteriore importante inconveniente consiste nel fatto, che sulle superfici opacizzate in rilievo, in condizioni di luce normali, gi? ad occhio nudo ? possibile percepire anche modestissime differenze nel grado di opacizzazione, il che nel caso di impostazione non uniforme del grado di opacizzazione, nell'acido di incisione chimica, porta partimenti ad un influenzamento negativo dell'estetica. Questo inconveniente ? tanto pi? grave, poich? un'esatta impostazione del grado di opacizzazione nel bagno di incisione chimica, ammesso che sia possibile, comporta un considerevole dispendio supplementare. A further important drawback consists in the fact that on the opaque surfaces in relief, in normal light conditions, already? with the naked eye? It is possible to perceive even very modest differences in the degree of opacification, which in the case of non-uniform setting of the degree of opacification, in the acid of chemical etching, leads to a negative influence of aesthetics. This inconvenience? much more? serious, since? an exact setting of the degree of opacification in the chemical etching bath, if this is possible, entails a considerable additional effort.
L'invenzione si pone il compito, di sviluppare un procedimento, che permette la produzione di superfici strutturate su lamiere, cilindri, nastri senza fine o similari in metalli ferrosi o non ferrosi, in cui i punti di opacizzazione sono ribassati, mentre i punti lucidi appaiono in rilievo, laddove si pu? fare a meno di un trattamento di opacizzazione in un bagno di incisione chimica. The invention has the task of developing a process that allows the production of structured surfaces on sheets, cylinders, endless strips or similar in ferrous or non-ferrous metals, in which the opacification points are lowered, while the shiny points appear in relief, where you can? do without an opacification treatment in a chemical etching bath.
Ci? si ottiene secondo l'invenzione per il fatto, che la lamiera o materiale similare, prima dell'applicazione dell'inchiostro da stampa viene irruvidita meccanicamente in sostanza sull'intera superficie e prima di togliere I'inchiostro viene lucidata elettroliticamente o chimicamente nel bagno di trattamento. There? it is obtained according to the invention due to the fact that the sheet metal or similar material, before the application of the printing ink is substantially mechanically roughened on the entire surface and before removing the ink it is electrolytically or chemically polished in the treatment.
Con il procedimento, secondo l'invenzione, ? ora possible produrre riproduzioni di disegni, qualitativamente pregievoli, di piastre di materiale sintetico termo-indurente, termo-plastico, pannelli truciolari in legno e similari, in cui i punti opachi sono Intagliati nella superficie, mentre i punti licidi appaiono in rilievo. Poich? conformemente all'invenzione ? possibile fare a meno di un bagno di incisione elettrolitico o chimico per opacizzare superfici, vengono a mancare le difficolt?, risultanti nel caso di un bagno di incisione chimica, in relazione all'ottenimento di una impostazione uniforme del grado di opacizzazione. With the process, according to the invention,? now it is possible to produce reproductions of high quality drawings of plates of thermosetting synthetic material, thermo-plastic, chipboard panels in wood and the like, in which the opaque points are carved in the surface, while the glossy points appear in relief. Since? in accordance with the invention? It is possible to do without an electrolytic or chemical etching bath to opacify surfaces, there are no difficulties, resulting in the case of a chemical etching bath, in relation to obtaining a uniform setting of the degree of opacification.
Esempio di esecuzione: Execution example:
Una lamiera di ottone del tipo usuale in commercio", ? stata opacizzata (irruvidita) meccanicamente, sull'intera superficie, sul lato anteriore e su quello posteriore. Successivamente, la lamiera su entrambe le facce, corispondentemente al modello di stampa desiderato, ? stata stampigliata con un inchiostro resistente nei confronti di un trattamento di incisione chimica. A brass sheet of the usual type on the market "was opacified (roughened) mechanically, on the entire surface, on the front and on the back side. Subsequently, the sheet on both faces, corresponding to the desired printing pattern, was stamped with an ink resistant to a chemical etching treatment.
Successivamente, la lamiera cos? preventivamente trattata, ? stata introdotta in un bagno di lucidatura di tipo usuale in commercio, in cui durante un trattamento della durata di 10 minuti sono state lucidate le superfici opacizzate, non coperte dall'inchiostro da stampa. In una successiva fase, operativa, in maniera convenzionale, si ? tolto l'inchiostro con un solvente. Successivamente, Ja lamiera ? stata sottoposta ad una cromatura a spessore (si pu? fare a meno di questa fase del procedimento nel caso di lamiere o cilindri o similari fatti di acciaio). Nella lamiera trattata in tal modo, tutte ie superfici opache, preventivamente coperte di inchiostro, appaiono in rilievo, mentre le superfici nude (lucidate) appaiono ribassate. Dalla lamiera In una successiva fase di lavorazione, - si ? prodotta un'impronta su una piastra fatta di un laminato di materia arificiate, in cui le superfici opacizzate sono situate in profondit?, mentre quelle licidate appaiono in ri Iievo. Subsequently, the sheet metal cos? previously treated,? was introduced into a polishing bath of the usual type on the market, in which during a treatment lasting 10 minutes the opaque surfaces, not covered by the printing ink, were polished. In a subsequent operational phase, in a conventional way, yes? removed the ink with a solvent. Subsequently, Ja sheet metal? has been subjected to a thick chrome plating (you can do without this phase of the procedure in the case of sheets or cylinders or similar made of steel). In the sheet treated in this way, all the opaque surfaces, previously covered with ink, appear in relief, while the bare (polished) surfaces appear lowered. From sheet metal In a subsequent processing step, - yes? an imprint is produced on a plate made of a laminate of arified material, in which the opaque surfaces are located in depth, while the opaque ones appear in relief.
In base a questo procedimento, ? possibile trattare preventivamente, in maniera corrispondente nastri senza fine di metalli ferrosi o non ferrosi oppure cilindri, dai quali tutti i modelli di disegno immaginabili possono essere trasferiti su piastre di materiali sintetici termo-indurenti , termo-plastici, pannelli di trucioli di legno e similari. According to this procedure,? It is possible to treat in advance, in a corresponding manner, endless belts of ferrous or non-ferrous metals or cylinders, from which all imaginable design models can be transferred onto plates of thermosetting synthetic materials, thermo-plastic, wood chip panels and the like .
