“COMPONENTE RINFORZATA DEL VANO MOTORE DI UN VEICOLO DALL’ALTO VALORE ESTETICO” "REINFORCED COMPONENT OF THE ENGINE COMPARTMENT OF A VEHICLE WITH A HIGH AESTHETIC VALUE"
Descrizione Description
Campo della tecnica Field of technique
La presente invenzione opera nell’ambito dell’industria dell’automotive, in particolare per la realizzazione di componenti del vano motore di un veicolo. Più dettagliatamente, gli oggetti realizzati secondo la presente invenzione, sono prodotti mediante stampaggio a iniezione utilizzando un blend di polimeri rinforzato con fibra di vetro. Oltre alle prestazioni meccaniche, la presente invenzione pone l’accento sulla resa estetica dei pezzi realizzati, secondo gli standard elevatissimi che ormai il settore dell’automotive impone. The present invention operates in the automotive industry, in particular for the construction of components of the engine compartment of a vehicle. More specifically, the objects made according to the present invention are produced by injection molding using a blend of polymers reinforced with glass fiber. In addition to mechanical performance, the present invention emphasizes the aesthetic performance of the pieces made, according to the very high standards that the automotive sector now imposes.
Arte nota Known art
Le materie plastiche attualmente esistenti sono numerosissime. Esse possono essere costituite da polimeri puri oppure miscelati con additivi o cariche. I polimeri più utilizzati sono prodotti a partire da sostanze derivate dal petrolio e sono il risultato della polimerizzazione di una quantità di molecole base per formare catene anche molto lunghe. Si parla di omopolimeri se il monomero è unico, copolimeri se il polimero è ottenuto da due o più monomeri diversi e di leghe polimeriche se il materiale è il risultato della miscelazione di due monomeri che polimerizzano senza combinarsi chimicamente. The plastics currently existing are very numerous. They can be made up of pure polymers or mixed with additives or fillers. The most used polymers are produced starting from substances derived from petroleum and are the result of the polymerization of a quantity of basic molecules to form even very long chains. We speak of homopolymers if the monomer is unique, copolymers if the polymer is obtained from two or more different monomers and polymeric alloys if the material is the result of the mixing of two monomers that polymerize without chemically combining.
Un sottogruppo dei materiali polimerici è quello dei polimeri termoplastici. Essi acquistano malleabilità sotto l’azione del calore e sono utilizzati nei processi di stampaggio a iniezione. A subgroup of polymeric materials is that of thermoplastic polymers. They acquire malleability under the action of heat and are used in injection molding processes.
Attualmente la quasi totalità delle componenti plastiche dell’industria automobilistica è realizzata mediante un processo di stampaggio utilizzando polimeri termoplastici come le poliammidi 6, 66 e le loro co-poliammidi. Currently, almost all the plastic components of the automotive industry are made through a molding process using thermoplastic polymers such as polyamides 6, 66 and their co-polyamides.
Le poliammidi presentano in generale un’elevata resistenza agli urti e mantengono buone proprietà in un intervallo di temperatura ampio da -80°C a 140°C e, seppure per un intervallo di tempo limitato, fino a 210°C. La poliammide 66 presenta una temperatura di transizione vetrosa di circa 50°C e una temperatura di fusione di circa 255-265°C. A fronte di queste vantaggiose caratteristiche, però, le poliammidi presentano la criticità di un’elevata capacità di assorbimento di acqua con conseguenti variazioni dimensionali dei pezzi e diminuzione della rigidità. Polyamides generally have a high impact resistance and maintain good properties in a wide temperature range from -80 ° C to 140 ° C and, albeit for a limited time, up to 210 ° C. Polyamide 66 has a glass transition temperature of about 50 ° C and a melting temperature of about 255-265 ° C. In view of these advantageous characteristics, however, polyamides present the criticality of a high water absorption capacity with consequent dimensional variations of the pieces and a decrease in rigidity.
Alcune privative internazionali hanno come oggetto dei materiali termoplastici a base di poliammide per la risoluzione di alcuni problemi di stampaggio, in particolare nel settore dell’automotive, come, ad esempio, il brevetto statunitense US 8865821 dal titolo “Polyamide moulding composition and use thereof”. Questo brevetto riguarda proprio un materiale composito termoplastico da utilizzare nell’industria automobilistica. Il materiale è costituito da una percentuale compresa tra il 20% e l’88% in peso di poliammide o una miscela di poliammidi e una percentuale compresa tra il 10% e il 60% in peso di fibre aggregate, preferibilmente fibra di vetro, oltre ad una percentuale compresa tra il 2% ed il 10% in peso di additivi. Some international patents have as their object polyamide-based thermoplastic materials for solving some molding problems, in particular in the automotive sector, such as, for example, the US patent US 8865821 entitled "Polyamide molding composition and use thereof" . This patent relates to a thermoplastic composite material to be used in the automotive industry. The material consists of a percentage between 20% and 88% by weight of polyamide or a mixture of polyamides and a percentage between 10% and 60% by weight of aggregated fibers, preferably glass fiber, in addition to at a percentage between 2% and 10% by weight of additives.
In primo luogo l’eccessivo range rivendicato e, secondariamente l’inefficacia della lega di polimeri proposta, fanno sì che questa privativa, come le altre attualmente operanti sul mercato, non abbiamo ancora individuato una lega polimerica termoplastica opportunamente rinforzata per ovviare alle criticità proprie della poliammide appena citate. Firstly, the excessive range claimed and, secondly, the ineffectiveness of the proposed polymer alloy, mean that this patent, like the others currently operating on the market, has not yet identified a thermoplastic polymer alloy suitably reinforced to overcome the criticalities of the polyamide just mentioned.
Altri due brevetti Giapponesi appartenenti al medesimo titolare (JP2006348107; JP2004099813) rivendicano un materiale termoplastico rinforzato senza specificarne l’ambito di applicazione. Anche nel caso di questi due brevetti il range rivendicato delle varie componenti del materiale è decisamente troppo ampio per poter giungere in maniera intuitiva a quale possa essere lo scopo dei suddetti brevetti. Two other Japanese patents belonging to the same owner (JP2006348107; JP2004099813) claim a reinforced thermoplastic material without specifying the scope of application. Also in the case of these two patents, the claimed range of the various components of the material is decidedly too wide to be able to intuitively arrive at the purpose of the aforementioned patents.
In nessuna delle privative attualmente in essere, inoltre, è preso in considerazione il fattore estetico che, in particolare nel settore industriale al quale si riferisce la presente invenzione, è ormai uno standard della medesima importanza delle prestazioni meccaniche. Furthermore, in none of the currently existing patent rights is the aesthetic factor taken into consideration which, in particular in the industrial sector to which the present invention refers, is now a standard of the same importance as mechanical performance.
Un altro materiale piuttosto diffuso nei processi di stampaggio è il polifenilensulfide (abbreviato: PPS), che è una resina termoplastica resistente alle alte temperature. Il PPS ha una temperatura di transizione vetrosa di circa 80°C e temperatura di fusione di 280-290°C. Il PPS, inoltre, presenta una buona stabilità dimensionale, stabilità termica, proprietà elettriche, resistenza alla fatica e resistenza chimica. Più dettagliatamente il PPS può essere utilizzato in continuo fino a 240°C, resiste a picchi di temperatura fino a 270°C, è insolubile in tutti i solventi noti fino a 200°C, è autoestinguente, presenta un’elevatissima resistenza alla deformazione, anche ad alte temperature e un bassissimo assorbimento di acqua. Tuttavia, il PPS è piuttosto fragile, ha una bassa resistenza all’urto, presenta difficoltà nello stampaggio ad iniezione ed ha anche un costo elevato. Tutte caratteristiche che non lo rendono utilizzabile, da solo, per la realizzazione di componenti di un veicolo, in particolare del vano motore. Another widely used material in molding processes is polyphenylene sulfide (abbreviated: PPS), which is a thermoplastic resin resistant to high temperatures. PPS has a glass transition temperature of about 80 ° C and a melting temperature of 280-290 ° C. Furthermore, PPS has good dimensional stability, thermal stability, electrical properties, fatigue resistance and chemical resistance. More specifically, PPS can be used continuously up to 240 ° C, resists temperature peaks up to 270 ° C, is insoluble in all known solvents up to 200 ° C, is self-extinguishing, has a very high resistance to deformation, even at high temperatures and very low water absorption. However, PPS is quite fragile, has a low impact resistance, presents difficulties in injection molding and also has a high cost. All features that do not make it usable, on its own, for the construction of vehicle components, in particular the engine compartment.
Scopo della presente invenzione è quello di realizzare componenti del vano motore di un qualsiasi veicolo tramite un nuovo ed innovativo polimero termoplastico rinforzato che sia in grado di superare le criticità proprie dei materiale sino ad oggi utilizzati e che consenta di mantenere elevati standard sia tecniche che estetici. The purpose of the present invention is to make components of the engine compartment of any vehicle by means of a new and innovative reinforced thermoplastic polymer that is able to overcome the criticalities of the materials used up to now and that allows to maintain high technical and aesthetic standards. .

Componenti dalle prestazioni meccaniche differenti e prestabilite possono essere realizzate a partire da concentrazioni diverse dei tre materiali che costituiscono il composito, purché comprese nei seguenti range: Components with different and pre-established mechanical performances can be made starting from different concentrations of the three materials that make up the composite, as long as they are included in the following ranges:
- poliammide 66 (PA66), in una concentrazione compresa tra il 45% ed il 52% in peso; - polyamide 66 (PA66), in a concentration between 45% and 52% by weight;
- polifenilensulfide (PPS), tra il 18% ed il 23% in peso; - polyphenylene sulfide (PPS), between 18% and 23% by weight;
- fibra di vetro, in una concentrazione compresa tra il 28% ed il 35% in peso. - glass fiber, in a concentration between 28% and 35% by weight.
Oltre all’estrema prevedibilità di densità, prestazioni meccaniche e spessori di tutte le componenti del vano motore realizzate con il materiale composito suddetto, esse sono anche conformi agli standard estetici ad oggi richiesti nel mondo dell’automotive. Una volta estratta la componente appena realizzata dallo stampo a iniezione, infatti, nessuno dei tre polimeri che costituiscono il composito è distinguibile dagli altri, apparendo tutto un medesimo materiale privo di macchie e di qualsiasi tipo di imperfezione. In addition to the extreme predictability of density, mechanical performance and thickness of all the components of the engine compartment made with the aforementioned composite material, they also comply with the aesthetic standards currently required in the automotive world. Once the component just made from the injection mold has been extracted, in fact, none of the three polymers that make up the composite are distinguishable from the others, appearing all the same material free of stains and any type of imperfection.
