Thanks to the present invention, ? possible to obtain a panel that is sustainable, versatile, and economical and that has good mechanical performance.
Descrizione dettagliata dell?invenzione Detailed description of the invention
Anche qualora non esplicitamente evidenziato, le singole caratteristiche descritte in riferimento alle specifiche realizzazioni dovranno intendersi come accessorie e/o intercambiabili con altre caratteristiche, descritte in riferimento ad altri esempi di realizzazione. Even if not explicitly highlighted, the individual characteristics described with reference to the specific embodiments must be understood as accessory and/or interchangeable with other characteristics, described with reference to other embodiments.
La presente invenzione ha per oggetto un pannello di supporto idoneo a varie applicazioni, illustrate nel seguito. The present invention relates to a support panel suitable for various applications, illustrated below.
Il pannello secondo la presente invenzione comprende uno strato di materiale composito. In particolare, lo strato di materiale composito comprende una matrice comprendente una resina termoplastica o termoindurente. Preferibilmente, tale resina ? una bioresina a base di poliestere. The panel according to the present invention comprises a layer of composite material. In particular, the layer of composite material comprises a matrix comprising a thermoplastic or thermosetting resin. Preferably, this resin? a polyester-based bioresin.
Lo strato di materiale composito comprende inoltre elementi di rinforzo dispersi all?interno della matrice. Gli elementi di rinforzo comprendono preferibilmente fibre. In particolare, tali fibre sono scelte tra uno o pi? nel gruppo composto da fibre di vetro, fibre di carbonio, fibre naturali. The layer of composite material also comprises reinforcing elements dispersed within the matrix. The reinforcing elements preferably comprise fibers. In particular, these fibers are selected from one or more in the group composed of glass fibers, carbon fibers, natural fibers.
Lo strato di materiale composito comprende inoltre cariche minerali, vegetali o organiche, altres? note come bio-filler. Tali cariche hanno la funzione di riempitivo, e sono preferibilmente in forma di polvere. Ad esempio, tali cariche comprendono carbonato di calcio o altre cariche di origine vegetale o organica. The layer of composite material also includes mineral, vegetable or organic fillers, as well as? known as bio-fillers. These fillers have the function of filler, and are preferably in the form of a powder. For example, such fillers include calcium carbonate or other fillers of vegetable or organic origin.
Giova rilevare che, in accordo con la presente invenzione, lo strato di materiale composito comprende un materiale di recupero disperso nella matrice. Il materiale di recupero ? in particolare scelto tra PET riciclato e/o segatura di legno (nel seguito: segatura). In altre parole, una prima forma realizzativa di pannello secondo la presente invenzione prevede la presenza di PET riciclato all?interno della matrice. In accordo con una seconda forma realizzativa, alternativa alla prima, il pannello presenta segatura anzich? PET riciclato all?interno della matrice. Secondo una terza forma realizzativa, il pannello comprende sia PET riciclato che segatura all?interno della matrice. It should be noted that, in accordance with the present invention, the layer of composite material comprises a recovery material dispersed in the matrix. The recycled material? in particular chosen from recycled PET and/or wood sawdust (hereinafter: sawdust). In other words, a first embodiment of the panel according to the present invention provides for the presence of recycled PET inside the matrix. In accordance with a second embodiment, alternative to the first, the panel has sawdust instead of Recycled PET inside the matrix. According to a third embodiment, the panel comprises both recycled PET and sawdust within the matrix.
Tali tre forme realizzative prevedono diverse applicazioni, in relazione al fatto che il PET riciclato fornisce migliori prestazioni meccaniche al pannello rispetto ad un pannello realizzato senza PET riciclato. D?altro canto, la segatura ha la funzione di assorbire acqua, contribuendo in tal senso a mantenere umido il pannello. These three embodiments have different applications, in relation to the fact that the recycled PET provides better mechanical performances to the panel compared to a panel made without recycled PET. On the other hand, the sawdust has the function of absorbing water, thus helping to keep the panel moist.
Il pannello secondo la prima e la terza forma realizzativa ? utilizzabile per l?inverdimento di aree urbane e periurbane, ad esempio per la realizzazione di pareti verdi verticali o di orti ergonomici. The panel according to the first and third embodiments? usable for the greening of urban and peri-urban areas, for example for the creation of vertical green walls or ergonomic vegetable gardens.
Il pannello in accordo con la seconda forma realizzativa ? utilizzabile per la realizzazione di quadri elettrici, pannelli di carrozzeria di veicoli e pannelli di rivestimento esposti ad agenti atmosferici. The panel in accordance with the second embodiment? usable for making electrical switchboards, vehicle body panels and cladding panels exposed to atmospheric agents.
In accordo con la prima e la terza forma realizzativa della presente invenzione, il pannello comprende uno strato di tessuto composto di fibre naturali. Tale strato di tessuto ? posto a contatto con lo strato di materiale composito. In accordance with the first and third embodiments of the present invention, the panel comprises a fabric layer composed of natural fibers. That layer of fabric? placed in contact with the layer of composite material.
Preferibilmente, tale strato di tessuto comprende fibre di lino e/o canapa. Preferably, this fabric layer comprises flax and/or hemp fibers.
Sempre in accordo con la prima e la terza forma realizzativa della presente invenzione, il pannello comprende uno strato di specie vegetale. Lo strato di specie vegetale comprende ad esempio una o pi? specie di muschio. Tale strato di specie vegetale ? in particolare posto a contatto con lo strato di tessuto, in quanto il tessuto, essendo composto di fibre naturali, favorisce l?attacco della specie vegetale. Pertanto, in accordo con tali forme realizzative, lo strato di tessuto ? interposto tra lo strato di materiale composito e lo strato di specie vegetale. Again in accordance with the first and third embodiments of the present invention, the panel comprises a layer of plant species. The layer of plant species includes, for example, one or more? species of moss. This layer of plant species ? in particular placed in contact with the layer of fabric, since the fabric, being composed of natural fibers, favors the attack of the plant species. Therefore, in accordance with these embodiments, the layer of fabric is interposed between the layer of composite material and the layer of plant species.
Giova rilevare che il pannello secondo la presente invenzione ? ottenuto per stampaggio a compressione di un pre-impregnato, a cui viene aggiunto il materiale di recupero. In particolare, il pre-impregnato comprende le sopracitate resina termoplastica o termoindurente, fibre e cariche minerali, vegetali o organiche. It should be noted that the panel according to the present invention ? obtained by compression molding of a prepreg, to which the recycled material is added. In particular, the prepreg comprises the aforementioned thermoplastic or thermosetting resins, fibers and mineral, vegetable or organic fillers.
La presente invenzione ? pertanto relativa anche ad un processo per realizzare il pannello secondo la presente invenzione. The present invention ? therefore also relating to a process for making the panel according to the present invention.
Il processo per realizzare il pannello secondo la presente invenzione comprende una prima fase di preparazione del sopracitato pre-impregnato comprendente la resina termoplastica o termoindurente, le fibre e le cariche minerali, vegetali o organiche. Il pre-impregnato comprende inoltre un catalizzatore configurato per attivare il processo di catalisi all?interno della resina durante la successiva fase di stampaggio. The process for making the panel according to the present invention comprises a first step of preparing the aforementioned pre-preg comprising the thermoplastic or thermosetting resin, the fibers and the mineral, vegetable or organic fillers. The prepreg further comprises a catalyst configured to activate the catalysis process within the resin during the subsequent molding step.
Dopo la fase di preparazione del pre-impregnato, il processo comprende quindi una fase di maturazione del pre-impregnato normalmente della durata di alcuni giorni. Successivamente a tale fase di maturazione, il pre-impregnato viene disposto in uno stampo. Tale stampo ? preferibilmente uno stampo metallico. After the pre-preg preparation step, the process therefore comprises a pre-preg curing step which normally lasts a few days. After this stage of maturation, the prepreg is placed in a mould. This mold? preferably a metal mold.
Il processo comprende inoltre una fase di aggiunta del materiale di recupero al preimpregnato. In particolare, tale fase di aggiunta del materiale di recupero al preimpregnato pu? essere eseguita in una fase precedente o successiva alla disposizione nello stampo del pre-impregnato. The process further comprises a step of adding the recovery material to the prepreg. In particular, this step of adding the recovery material to the prepreg can be performed in a step before or after placing the prepreg in the mould.
Tale fase di aggiunta del materiale di recupero al pre-impregnato viene eseguita a mano o a macchina. This step of adding the recovered material to the pre-preg is performed by hand or by machine.
Opzionalmente, la fase di aggiunta del materiale di recupero al pre-impregnato ? seguita da una fase di mescolamento del materiale di recupero al fine di disporlo in modo omogeneo all?interno del pre-impregnato. Ci? avviene ad esempio nel caso della seconda e della terza forma realizzativa. Optionally, the step of adding the recovery material to the pre-preg is followed by a mixing phase of the recovered material in order to arrange it homogeneously inside the pre-preg. There? occurs for example in the case of the second and third embodiments.
Preferibilmente, il PET riciclato ? aggiunto in forma di fogli. Preferably, recycled PET? added in sheet form.
Il processo comprende quindi una fase di chiusura dello stampo per poter stampare a compressione il pannello. Infatti, segue una fase successiva di stampaggio del pannello, che prevede di instaurare le corrette condizioni di pressione e temperatura nello stampo. Preferibilmente, tali condizioni prevedono pressioni comprese tra 50 e 100 bar ed una temperatura di 150?C. Tale temperatura viene raggiunta scaldando lo stampo, ed innesca la reticolazione della resina. In accordo con la prima e la terza forma realizzativa della presente invenzione, durante tale fase il PET riciclato reticola insieme alla resina formando un unico blocco. The process therefore includes a phase for closing the mold in order to be able to press-mould the panel. In fact, a subsequent phase of molding of the panel follows, which involves establishing the correct pressure and temperature conditions in the mould. Preferably, these conditions provide for pressures ranging from 50 to 100 bars and a temperature of 150°C. This temperature is reached by heating the mold, and triggers the cross-linking of the resin. In accordance with the first and third embodiments of the present invention, during this step the recycled PET crosslinks together with the resin forming a single block.
Opzionalmente, il processo comprende una fase di disporre il tessuto nello stampo. Tale fase viene eseguita precedentemente alla chiusura dello stampo e successivamente all?aggiunta del materiale di recupero al pre-impregnato. In questo modo il tessuto forma uno strato adiacente allo strato di materiale composito, rendendo favorita, in un secondo momento, l?applicazione dello strato di specie vegetale, quale ad esempio muschio. Optionally, the process includes a step of arranging the fabric in the mold. This step is performed before the mold is closed and after the addition of the recovery material to the pre-impregnated product. In this way the fabric forms a layer adjacent to the layer of composite material, facilitating, at a later stage, the application of the layer of plant species, such as moss for example.
