Description
Descrizione di un brevetto per invenzione industriale per il trovato avente titolo: Description of a patent for industrial invention for the invention entitled:
"COMPOSIZIONE DI UN MATERIALE AGGLOMERATO, PREFERIBILMENTE A BASE DI PVC O TR, CON PARTICOLARI COMPONENTI, PER LO STAMPAGGIO DI SOTTOPIEDI E SUOLE DI CALZATURE" "COMPOSITION OF AN AGGLOMERATED MATERIAL, PREFERABLY BASED ON PVC OR TR, WITH PARTICULAR COMPONENTS, FOR THE MOLDING OF INSOLES AND SOLES OF FOOTWEAR"
Il presente brevetto d'invenzione ha per oggetto la particolare composizione di un materiale costituito da un agglomerato di una materia plastica, preferibilmente PVC o TR ed altri opportuni componenti, utilizzabile per la produzione di sottopiedi e suole per calzature mediante stampaggio. The present invention patent relates to the particular composition of a material consisting of an agglomerate of a plastic material, preferably PVC or TR and other suitable components, usable for the production of insoles and soles for footwear by means of molding.
Secondo la tecnica attuai mente in uso, per la produzione, mediante stampaggio ad iniezione od intrusione, di sottopiedi o suole per calzature, vengono utilizzati materiali diversi tra i quali anche materiali plastici come il PVC (Polivinilcloruro) od il TR (Gomma Termoplastica). According to the technique currently in use, different materials are used for the production, by injection or intrusion molding, of insoles or soles for shoes, including plastic materials such as PVC (Polyvinyl chloride) or TR (Thermoplastic Rubber).
E' stato tuttavia riscontrato, con l'utilizzo di questi materiali, che i costi sempre più elevati della materia prima tradizionalmente impiegata sono tali da impedire il contenimento delle spese di produzione e conseguentemente di commercializzazione dei manufatti, rendendo così da un lato più difficile ottenere un cospicuo ricavo dell'attività e dall'altro necessario, nello specifico settore tecnologico, cercare di individuare materiali più economici anche se esteticamente validi e con resistenze meccaniche adeguate. However, it has been found, with the use of these materials, that the increasingly higher costs of the traditionally used raw material are such as to prevent the containment of production costs and consequently of marketing of the products, thus making it more difficult to obtain a substantial income from the activity and on the other hand it is necessary, in the specific technological sector, to try to identify cheaper materials even if aesthetically valid and with adequate mechanical strength.
Scopo della presente invenzione è quello di eliminare o quantomeno ridurre gli inconvenienti sopracitati dovuti ai costi delle materie prime impiegate per lo stampaggio di sottopiedi e/o suole di calzature o similari, ed in particolare di fornire ai produttori dei manufatti sopracitatl un idoneo materiale che può essere stampato con le macchine tradizionali, quali le presse ad iniezione od intrusione atte allo stampaggio del PVC (Polivinilcloruro) plastificato o del TR (gomma termoplastica) normale, per ottenere manufatti esteticamente validi con resistenze meccaniche adeguate e soprattutto con un buon abbassamento dei costi nell'acquisto delle materie prime in rapporto ai materiali similari tradizionalmente impiegati ed attualmente commercializzati. . The purpose of the present invention is to eliminate or at least reduce the aforementioned drawbacks due to the costs of the raw materials used for the molding of insoles and / or soles of footwear or the like, and in particular to provide the manufacturers of the aforementioned products with a suitable material that can be molded with traditional machines, such as injection or intrusion presses suitable for molding plasticized PVC (Polyvinyl chloride) or normal TR (thermoplastic rubber), to obtain aesthetically valid products with adequate mechanical strength and above all with a good lowering of costs in the '' purchase of raw materials in relation to similar materials traditionally used and currently marketed. .
Tali scopi e vantaggi vengono raggiunti, secondo il presente trovato, da un agglomerato costituito da materia plastica preferibilmente PVC o TR ed altri particolari componenti, per lo stampaggio di sottopiedl e/o suole di calzature, il quale si caratterizza particolarmente per il fatto che ad un composto di base preferibilmente PVC (Polivinilcloruro) o TR plastificato vengono amalgamate, durante la lavorazione, parti di sughero macinato e parti di lolla di risone per l'ottenimento di granuli grazie all'utilizzo di un estrusore bivite granulatore o similare, per la successiva distribuzione. These objects and advantages are achieved, according to the present invention, by an agglomerate consisting of plastic material preferably PVC or TR and other particular components, for the molding of shoe insoles and / or soles, which is particularly characterized in that a base compound preferably PVC (Polyvinyl chloride) or plasticized TR are amalgamated, during processing, parts of ground cork and parts of paddy husk to obtain granules thanks to the use of a granulator or similar twin screw extruder, for the subsequent distribution.
Ulteriori caratteristiche e particolari del presente trovato potranno meglio apparire nella descrizione che segue di tipi di composizione e di esecuzione preferenzial l. Further characteristics and details of the present invention will better appear in the following description of types of composition and preferential embodiments.
In accordo alla presente invenzione, come accennato sopra, la composizione comprende del materiale plastico di base al quale si aggiungono, in fase di preparazione del composto, quantitativi variabili di sughero macinato e lolla di risone come si trova in natura. In accordance with the present invention, as mentioned above, the composition comprises basic plastic material to which variable quantities of ground cork and paddy husk as found in nature are added during the preparation of the compound.
I materiali plastici di base sono di due tipi diversi: a) Polivinilcloruro (PVC) plastificato; The basic plastic materials are of two different types: a) Plasticized polyvinyl chloride (PVC);
b) Gomma Termoplastica (TR). b) Thermoplastic Rubber (TR).
Nel caso in cui il materiale plastico sia PVC plastificato, viene prodotto un composto con le attrezzature, 1 componenti ed i metodi tradizionali ed universalmente noti, preparando una mescola di base in turbomi scelatore di idonea durezza, ad esempio Shore A = 45÷50. In the event that the plastic material is plasticized PVC, a compound is produced with the traditional and universally known equipment, components and methods, preparing a basic mixture in turbomixer of suitable hardness, for example Shore A = 45 ÷ 50.
A questo composto viene aggiunto sughero macinato e lolla di risone secondo le formulazioni sotto riportate a solo titolo indicativo per mescole di durezza media: Ground cork and paddy husk are added to this compound according to the formulations given below as an indication only for medium hardness mixes:
- PER RESINA BASE PVC PLASTIFICATO: - FOR PLASTICATED PVC BASE RESIN:
parti peso Resina PVC sospensione K = 60*80 100 Plastificante ftalico (es. OOP o similare) 100 Stabilizzante (es. Calcio/Zinco in polvere) 5 Acido stearico 0,5 Olio di soia epossidato 6 Sughero macinato 30*50 Lolla di risone 30*50 Per ottenere mescole di durezze diverse da quella media indicata nella composizione, è necessario variare le proporzioni tra resina e plastificante. parts weight Resin PVC suspension K = 60 * 80 100 Phthalic plasticizer (eg OOP or similar) 100 Stabilizer (eg Calcium / Zinc powder) 5 Stearic acid 0.5 Epoxidized soybean oil 6 Ground cork 30 * 50 Paddy husk 30 * 50 To obtain compounds of different hardness than the average indicated in the composition, it is necessary to vary the proportions between resin and plasticizer.
Il composto ottenuto viene trasformato successivamente in granuli per mezzo di un estrusore bivite granulatore o similare e detti granuli possono quindi essere imballati in sacchi di carta, o similari. The compound obtained is subsequently transformed into granules by means of a twin-screw granulator or similar extruder and said granules can then be packaged in paper bags or the like.
- PER RESINA DI BASE TR: - FOR TR BASE RESIN:
Calprene 485: 125 Calprene 485: 125
Olio paraffinico: 45 Paraffin oil: 45
Lolla di riso e/o sughero trattato: 10-ί30 Rice husk and / or treated cork: 10-ί30

Anche in questo caso la trasformazione in granuli avviene a mezzo di un estrusore bivite granulatore o sImilare. Also in this case the transformation into granules takes place by means of a twin screw granulator or similar extruder.
La composizione del materiale in oggetto, per lo stampaggio di sottopiedl e suole di calzature, è stata descritta secondo una soluzione preferenziale, ma possono essere previste alcune varianti, tecnicamente equivalenti ai componenti citati, che sono quindi da ritenersi comprese nell'ambito di protezione del presente trovato. The composition of the material in question, for the molding of shoe insoles and soles, has been described according to a preferential solution, but some variants can be envisaged, technically equivalent to the aforementioned components, which are therefore to be considered included in the scope of protection of the present invention.
