DESCRIZIONE DESCRIPTION
PRODOTTO PROFILATO IN MATERIALE COMPOSITO COMPOSITE PROFILE PRODUCT
Campo tecnico dell’invenzione Technical field of the invention
Il presente trovato concerne i profilati in materiale composito del tipo conosciuti sul mercato come prodotti WPC (Wood Plastic Composite -composti in legno e materiale plastico) e che sono stati sviluppati per sostituire o rimpiazzare l’utilizzazione di legno naturale. The present invention relates to composite material profiles of the type known on the market as WPC products (Wood Plastic Composite - made of wood and plastic material) and which have been developed to replace or replace the use of natural wood.
In questi prodotti la componente legnosa, solitamente allo stato di polvere o fibre di diversa lunghezza, è normalmente ottenuta dal riciclo di prodotti in legno, o recuperando trucioli e scarti di legno, segatura ecc. ; la componente plastica è normalmente ottenuta da polimeri ad alta o bassa densità, quali ad esempio PE (polietilene), PP (polipropilene) e PVC (polivinilcloruro). Nella produzione di prodotti WPC possono poi essere utilizzati diversi tipi di additivi (o prodotti ausiliari o cariche) in funzione delle caratteristiche del materiale che si vuole ottenere; ad esempio prodotti ausiliari o cariche per prevenire la degradazione del prodotto, oppure o anche prodotti ausiliari che contribuiscono a rendere il prodotto autoestinguente al fuoco, oppure o anche prodotti stabilizzatori ai raggi UV ecc. In these products the wood component, usually in the state of dust or fibers of different lengths, is normally obtained from the recycling of wood products, or by recovering wood shavings and waste, sawdust, etc. ; the plastic component is normally obtained from high or low density polymers, such as for example PE (polyethylene), PP (polypropylene) and PVC (polyvinyl chloride). In the production of WPC products, different types of additives (or auxiliary products or fillers) can be used according to the characteristics of the material to be obtained; for example auxiliary products or fillers to prevent degradation of the product, or even auxiliary products that contribute to making the product self-extinguishing to fire, or even UV stabilizing products, etc.
Il materiale risultante da queste composizioni può essere lavorato come i materiali plastici; per esempio può essere iniettato attraverso uno stampo o estruso attraverso una trafila per realizzare un prodotto finito, come ad esempio profilati (o listelli) per la realizzazione di rivestimenti di pavimentazioni o di pareti in campo edilizio, o anche per il rivestimento di prodotti d’arredamento. The resulting material from these compositions can be worked like plastic materials; for example, it can be injected through a mold or extruded through a die to create a finished product, such as profiles (or strips) for the construction of floor coverings or walls in the building field, or even for the covering of products of furniture.
Questi profilati vengono utilizzati, in modo particolare in campo edile per pavimentazioni esterne, il rivestimento di pareti di arredi o ambienti, per la realizzazione di zoccolature, battiscopa, bordature di aperture di vani, telai di finestre o serramenti ecc. These profiles are used, in particular in the construction field for external flooring, the covering of walls of furniture or environments, for the realization of skirting boards, skirting boards, edges of openings of compartments, window frames or doors and windows etc.
I materiali noti hanno dei limiti d’applicazione per pavimentazioni e rivestimenti d’interni e di arredi di pregio, dovuti principalmente al fatto che i profilati con essi ottenibili presentano fattori sfavorevoli quali: un basso livello di aspetto superficiale, bassa resistenza UV (sia per quanto riguarda la sensibilità alla luce, con conseguenti cambio di colore, sia per quanto riguarda le proprietà meccaniche, quindi la degradazione delle caratteristiche fisiche del prodotto per effetto dell’esposizione agli agenti atmosferici e alla luce). Ne consegue la necessità di trattare opportunamente i profilati ottenuti con materiali stabilizzanti, quali vernici trasparenti protettive/decorative o addirittura rivestimenti con carte decorative incollate alle superfici dei profilati destinate a rimanere esposte alla vista dell'osservatore. The known materials have application limits for interior flooring and cladding and for fine furnishings, mainly due to the fact that the profiles obtainable with them have unfavorable factors such as: a low level of surface appearance, low UV resistance (both for as regards the sensitivity to light, with consequent change of color, both as regards the mechanical properties, therefore the degradation of the physical characteristics of the product due to exposure to atmospheric agents and light). It follows the need to properly treat the profiles obtained with stabilizing materials, such as transparent protective / decorative paints or even coatings with decorative papers glued to the surfaces of the profiles destined to remain exposed to the view of the observer.
Scopo dellinvenzione . Purpose of the invention.
Scopo del presente trovato è pertanto quello di ovviare a questi inconvenienti attraverso la realizzazione di un prodotto profilato in materiale composito, del tipo WPC come sopra indicato, con caratteristiche tali che lo rendono di bella presentazione estetica (come grado di finitura superficiale con venature irregolari del tutto simili o paragonabili a quelle del legno naturale) e con superfici destinate a rimanere in vista, quindi esposte agli agenti atmosferici, rivestite con una pellicola (o film) trasparente - che, di conseguenza, non modifica le caratteristiche estetiche superficiali dei profilati - ottenuta in uno o più polimeri termoplastici, che aumenta le caratteristiche meccaniche di resistenza del profilato e che costituisce un ottimo filtro ai raggi UV, contribuendo al mantenimento, nel tempo d’opera, delle caratteristiche meccaniche ed estetiche del profilato. The purpose of the present invention is therefore to obviate these drawbacks by making a profiled product in composite material, of the WPC type as indicated above, with characteristics such that it has a beautiful aesthetic presentation (as a degree of surface finish with irregular veins of the all similar or comparable to those of natural wood) and with surfaces destined to remain in sight, therefore exposed to atmospheric agents, coated with a transparent film (or film) - which, consequently, does not modify the surface aesthetic characteristics of the profiles - obtained in one or more thermoplastic polymers, which increases the mechanical resistance characteristics of the profile and which constitutes an excellent filter against UV rays, contributing to the maintenance, over time, of the mechanical and aesthetic characteristics of the profile.
Grazie a queste sue caratteristiche, il prodotto profilato oggetto della presente invenzione si presta ottimamente ad applicazioni quali: pavimentazioni esterne ed interne, rivestimenti, decorazioni di pareti di arredi o di ambienti, schermi protettivi contro la penetrazione della luce del sole in ambienti, produzione di profilati finiti per la realizzazione di telai di porte per interni e di finestre con ottimo aspetto estetico. Thanks to these characteristics, the profiled product object of the present invention lends itself well to applications such as: external and internal flooring, cladding, decoration of walls of furniture or environments, protective screens against the penetration of sunlight into rooms, production of finished profiles for the production of interior door frames and windows with excellent aesthetic appearance.
Il prodotto profilato oggetto della presente invenzione si caratterizza strutturalmente per il fatto di presentare le sue superfici, tutte o almeno quelle destinate a rimanere esposte agli agenti esterni, rivestite da una pellicola o film termoplastico trasparente il quale risulta reso aderente permanentemente a dette superfici, su tutta la loro estensione superfi ciale, senza l’impiego di collanti o materiali adesivi, ma per semplice aderenza fisico-chimico-meccanica ottenuta nella fase di estrusione del prodotto profilato, di coestrusione di detto film termoplastico e contemporaneo fissaggio o saldatura di quest’ultimo sulle prescelte superfici del profilato per mezzo di azione termo-chimico-meccanica. The profiled product object of the present invention is structurally characterized by the fact that its surfaces, all or at least those destined to remain exposed to external agents, are coated with a transparent thermoplastic film or film which is made permanently adherent to said surfaces, on their entire surface extension, without the use of glues or adhesive materials, but by simple physical-chemical-mechanical adhesion obtained in the step of extrusion of the profiled product, of co-extrusion of said thermoplastic film and simultaneous fixing or welding of the latter on the selected surfaces of the profile by means of thermo-chemical-mechanical action.
Ulteriore caratteristica dei materiale profilato in oggetto è quella che le caratteristiche estetiche superficiali dei profilato finito e da rivestire col film trasparente protettivo possono essere e risultano determinate dal procedimento di estrusione e non da lavorazioni meccaniche o grafiche successive al processo di estrusione ed eseguite prima o dopo l’applicazione del film trasparente protettivo. A further characteristic of the profiled material in question is that the superficial aesthetic characteristics of the finished profile and to be coated with the transparent protective film can be and are determined by the extrusion process and not by mechanical or graphic processing subsequent to the extrusion process and carried out before or after. the application of the transparent protective film.

Conformemente ai disegni allegati, con 1 , 1 a e 1 b è stato indicato il corpo di uno spezzone di profilato, che potrebbe costituire, in più esemplari accosti l’uno all’altro lungo un loro fianco laterale, il rivestimento di una parete di un ambiente o di un elemento d’arredo (vedi Fig. 4), oppure il rivestimento di una pavimentazione (vedi Fig. 5), oppure ancóra essere utilizzato in opportune lunghezze per la realizzazione di zoccolature (vedi Fig. 6) oppure, opportunamente tagliato a misura, per la realizzazione di telai di serramenti quali porte e finestre (vedi Fig. 7). In accordance with the accompanying drawings, 1, 1 a and 1 b indicate the body of a section of section, which could constitute, in several examples, side by side along one of their lateral sides, the covering of a wall of a room or a piece of furniture (see Fig. 4), or the covering of a flooring (see Fig. 5), or still be used in suitable lengths for the construction of skirting boards (see Fig. 6) or, suitably cut made to measure, for the construction of window frames such as doors and windows (see Fig. 7).
il profilato secondo l’invenzione è realizzato in materiale composito, la cui mistura è preferibilmente ottenuta come segue: the profile according to the invention is made of composite material, the mixture of which is preferably obtained as follows:
- polvere di legno dal 15% al 70%; - wood dust from 15% to 70%;
- composti ausiliari o cariche, quali ad esempio plastificanti, ritardanti del fuoco, agenti espandenti, agenti accoppianti e pigmenti, in percentuale inferiore al 10%; - auxiliary compounds or fillers, such as plasticizers, fire retardants, blowing agents, coupling agents and pigments, in a percentage lower than 10%;
- composizione, in percentuale, rimanente formata da uno o più polimeri, scelti preferibilmente tra PVC (polivinilcloruro), PP (polipropilene) e PE (polietilene); - composition, in percentage, remaining formed by one or more polymers, preferably selected from PVC (polyvinyl chloride), PP (polypropylene) and PE (polyethylene);
- densità della composizione da 650 Kg/m3 a 1400 Kg/m3. - composition density from 650 Kg / m3 to 1400 Kg / m3.
Con 2 sono stati indicati spezzoni di film in materiale plastico destinati a rivestire le superfici dei profilati 1, 1 b, 1c ai fini di conferire ai profilati medesimi le caratteristiche indicate più sopra. With 2 have been indicated pieces of plastic film intended to cover the surfaces of the profiles 1, 1 b, 1c in order to give the profiles themselves the characteristics indicated above.
Gli spezzoni 2 sono realizzati utilizzando miscele di polimeri termoplastici trasparenti miscelati secondo esigenze prioritarie, che posso risultare: - di carattere tecnico, come ad esempio la resistenza all’abrasione, al graffio, all’indentazione, agli UV (raggi ultra violetti), alla flessione, al fuoco; The sections 2 are made using blends of transparent thermoplastic polymers mixed according to priority needs, which can be: - of a technical nature, such as resistance to abrasion, scratching, indentation, UV (ultra violet rays), bending, to fire;
- di percezione, come ad esempio opacità, lucentezza, morbidezza, durezza ecc. - of perception, such as opacity, luster, softness, hardness, etc.
Tali polimeri sono preferibilmente PVC (polivinilcloruro), MBS (polimetacrilato butadiene stirene, più specificamente termopolimero metilmetacrilato butadiene stirene) e PMMA (polimetilmetacrilato), in miscele che possono variare per ciascuno dei tre da 0% al 100% in base alle esigenze di cui sopra. These polymers are preferably PVC (polyvinyl chloride), MBS (polymethacrylate butadiene styrene, more specifically thermopolymer methyl methacrylate butadiene styrene) and PMMA (polymethyl methacrylate), in mixtures that can vary for each of the three from 0% to 100% according to the above requirements .
Ad esempio per applicazioni all'esterno si utilizza preferibilmente una quantità superiore al 60% di PMMA, per contenere la tendenza ad ingiallire in caso di esposizione diretta ai raggi UV. Per applicazioni in cui è preponderante la necessità di resistere agli urti e i graffi si utilizza preferibilmente una quantità superiore al 30% di MBS. Per usi comuni in cui il film ha funzione di protezione antimacchia, si utilizza preferibilmente una quantità superiore al 60% di PVC. For example, for outdoor applications, an amount greater than 60% of PMMA is preferably used, to limit the tendency to yellow in the event of direct exposure to UV rays. For applications in which the need to resist shocks and scratches is predominant, an amount greater than 30% of MBS is preferably used. For common uses in which the film has a stain protection function, an amount greater than 60% of PVC is preferably used.
Lo spessore dei film 2 può variare da 0,1 mm a diversi millimetri, in funzione del tipo di applicazione cui sono destinati i profilati 1. Ad esempio per l’utilizzo di profilati 1 per il rivestimento di pavimentazioni (figura 5) lo spessore dei film 2 può risultare compreso fra 0,3mm e 0,5mm. The thickness of the films 2 can vary from 0.1 mm to several millimeters, depending on the type of application for which the profiles 1 are intended. For example, for the use of profiles 1 for covering flooring (figure 5) the thickness of the film 2 can be between 0.3mm and 0.5mm.
L’unione stabile e permanente dei film 2 sulle superfici dei profilati 1 viene eseguita sfruttando le caratteristiche dei rispettivi materiali in cui risultano realizzate, procedendo (in contemporanea) alia coestrusione dei profilati 1 e dei film 2 e portando in aderenza i film 2 sulle superfici dei profilati 21 con una certa pressione ed in condizioni di temperatura tali da causare una sorta di saldatura dei film 2 sulle superfici dei profilati 1 per effetto termo-chimico-meccanico. The stable and permanent union of the films 2 on the surfaces of the profiles 1 is performed by exploiting the characteristics of the respective materials in which they are made, proceeding (at the same time) to the coextrusion of the profiles 1 and the films 2 and bringing the films 2 into adherence on the surfaces of the sections 21 with a certain pressure and in conditions of temperature such as to cause a sort of sealing of the films 2 on the surfaces of the sections 1 due to a thermo-chemical-mechanical effect.
Secondo una preferita forma di realizzazione dei profilati 1 , il relativo materiale composito viene preparato in modo tale per cui durante la fase di estrusione esso presenta le superfici caratterizzate da venature che possono essere in pasta e random in funzione dell’aspetto estetico desiderato According to a preferred embodiment of the sections 1, the relative composite material is prepared in such a way that during the extrusion phase it presents surfaces characterized by veins that can be in paste and random depending on the desired aesthetic appearance
Ad esempio la venatura può risultare più o meno presente, con colori più o meno contrastati rispetto al colore di fondo e presente in uno o più tonalità e varianti di colore. For example, the grain may be more or less present, with more or less contrasting colors compared to the background color and present in one or more shades and color variations.
Le caratteristiche tecniche innovative del prodotto profilato in materiale composito oggetto della presente invenzione possono essere così riassunte: The innovative technical characteristics of the composite profile product object of the present invention can be summarized as follows:
- alta resistenza al graffio e all’abrasione, grazie alla presenza del rivestimento delle superfici del profilato col film 2; - high resistance to scratching and abrasion, thanks to the presence of the surface coating of the profile with film 2;
- eliminazione di processi di verniciatura o comunque dì applicazione di protettivi del profilato estruso, grazie al fatto che la finitura superficiale del profilato è ottenuta in fase di estrusione e sulla base del materiale composito utilizzato e la protezione di tale finitura superficiale è ottenuta con l applicazione del film 2 per effetto termo-chimico-meccanico, quindi senza l’ausilio di collanti o comunque di sostanze adesive aggiuntive; - elimination of painting processes or in any case of application of protective products of the extruded profile, thanks to the fact that the surface finish of the profile is obtained in the extrusion phase and on the basis of the composite material used and the protection of this surface finish is obtained with the application of the film 2 due to the thermo-chemical-mechanical effect, therefore without the aid of adhesives or in any case of additional adhesive substances;
- riciclabilità totale del prodotto profilato nello stesso colore e con le medesime caratteristiche, grazie all’assenza di utilizzazione di vernici o sostanze adesive aggiuntive; - total recyclability of the profiled product in the same color and with the same characteristics, thanks to the absence of the use of paints or additional adhesive substances;
- resistenza migliorata ai raggi UV data dalla presenza dei film protettivi in materiale trasparente e che per loro natura offrono forte resistenza agli UV; - improved resistance to UV rays due to the presence of protective films in transparent material which by their nature offer strong resistance to UV;
- maggiore resistenza meccanica, in particoiar modo a flessione, urto e trazione. - greater mechanical resistance, in particular to bending, impact and traction.
