Description
La presente invenzione si riferisce ad una lega polimerica termoplastica ed ai materiali da essa ottenuti comprendente: The present invention relates to a thermoplastic polymer alloy and the materials obtained from it comprising:
a) un policarbonato di bisfenolo A; a) a bisphenol A polycarbonate;
b) uno o più polialchilentereftalati in cui il n° di atomi di carbonio del radicale alchilene è compreso fra 2 e 10; b) one or more polyalkylene terephthalates in which the number of carbon atoms of the alkylene radical is between 2 and 10;
c) un modificatore del meccanismo di assorbimento dell'energia di impatto scelto fra i seguenti: c) a modifier of the impact energy absorption mechanism chosen from the following:
I) una poliolefina del tipo C2 o C3 I) a polyolefin of the type C2 or C3
II) un copolimero olefinico C2-C3 (del tipo EPR o EPDM) II) a C2-C3 olefin copolymer (of the EPR or EPDM type)
III) una miscela di (I) con (II) III) a mixture of (I) with (II)
IV) una miscela di (I) con un copolimero del tipo polietilen-vinilacetato (EVA) IV) a mixture of (I) with a copolymer of the polyethylene-vinyl acetate (EVA) type
V) una miscela di (I), (II) e un copolimero del tipo polietilen-vinilacetato (EVA). V) a mixture of (I), (II) and a copolymer of the polyethylene-vinyl acetate (EVA) type.
II componente a è in quantità variabili fra 5 e 95 parti % in peso, i componenti b + c sono in quantità variabili fra 5 e 95 parti % in peso e il rapporto in peso fra il componente c_e il componente b è minore od uguale ad 1. The component a is in quantities varying between 5 and 95 parts% by weight, the components b + c are in quantities varying between 5 and 95 parts% by weight and the weight ratio between the component c_ and the component b is less than or equal to 1.
Il policarbonato usato è preferibilmente scelto tra quelli aventi viscosità intrinseca in cloruro di metilene a 20 °C compresa tra 0,46 e 1,2 dl/g. The polycarbonate used is preferably selected from those having intrinsic viscosity in methylene chloride at 20 ° C comprised between 0.46 and 1.2 dl / g.
Come modificatoli del meccanismo di assorbimento dell'energia d'impatto si possono usare semplicemente polietileni o polipropileni ma anche copolimeri di due o più olefine, quali ad esempio EPR (etilene-propilene) o EPDM (etilene-propilene-diene), o miscele di queste anche con un copolimero del tipo polietilen-vinilacetato (EVA). As modifiers of the impact energy absorption mechanism it is possible to use simply polyethylenes or polypropylenes but also copolymers of two or more olefins, such as for example EPR (ethylene-propylene) or EPDM (ethylene-propylene-diene), or mixtures of these also with a copolymer of the polyethylene vinyl acetate (EVA) type.
Sebbene non sia essenziale, i migliori risultati si ottengono operando uno o più premiscelamenti fra i componenti, riducendo la lega ottenuta in granuli e quindi stampandola. Non ha particolare importanza lo strumento utilizzato per operare il miscelamento. Adatti allo scopo sono quindi gli estrusori monovite, gli estrusori bivite, i mescolatori Banbury e tutte le macchine normalmente utilizzate nella pratica industriale. Although not essential, the best results are obtained by operating one or more premixings between the components, reducing the alloy obtained in granules and then printing it. The instrument used for mixing is not particularly important. Suitable for this purpose are single-screw extruders, twin-screw extruders, Banbury mixers and all the machines normally used in industrial practice.
La lega polimerica termoplastica di questa invenzione può presentarsi sotto diverse forme quali polveri, granuli, sfere, discoidi o altre, ottenute ad esempio o per estrusione o per iniezione. The thermoplastic polymer alloy of this invention can come in different forms such as powders, granules, spheres, discoids or others, obtained for example either by extrusion or by injection.
Questa lega può contenere diversi additivi quali stabilizzanti, coloranti, ritardanti di fiamma, lubrificanti o cariche (fibre di vetro, fibre di carbonio, fibre di amianto, lana di vetro, ...). This alloy can contain various additives such as stabilizers, dyes, flame retardants, lubricants or fillers (glass fibers, carbon fibers, asbestos fibers, glass wool, ...).
Esempi Examples
Tutti i dettagli operativi saranno evidenti dalla lettura dei seguenti esempi, che hanno il solo intento di illustrare l'invenzione senza limitarne gli scopi. All the operational details will be evident from the reading of the following examples, which have the sole purpose of illustrating the invention without limiting its purposes.
Esempi 1-77 Examples 1-77
I granuli essiccati dei componenti il blend vengono miscelati ed estrusi in un estrusore alla temperatura di 275°C. The dried granules of the components of the blend are mixed and extruded in an extruder at a temperature of 275 ° C.
• La lega polimerica cosi ottenuta viene quindi granulata e stampata ad iniezione a temperature variabili fra 260 e 280°C, a seconda della composizione, con una temperatura dello stampo di 60°C. • The polymer alloy thus obtained is then granulated and injection molded at temperatures ranging from 260 to 280 ° C, depending on the composition, with a mold temperature of 60 ° C.
Sui prodotti ottenuti sono stati effettuati i seguenti tests: The following tests were carried out on the products obtained:
a) Urto Izod con intaglio (metodo ASTM D 256-61) a) Notched Izod impact (ASTM D 256-61 method)
b) Punto di rammollimento Vicat a 5 kg (metodo ASTM D 1525-72) b) Vicat softening point at 5 kg (ASTM D 1525-72 method)
c) Modulo elastico in flessione (metodo ASTM D 790-70) c) Modulus of elasticity in flexion (ASTM D 790-70 method)

d) Prova di stress-cracking: d) Stress-cracking test:
si eseguono trazioni secondo il metodo ASTM D 638 su campioni precedentemente sottoposti ad una deformazione tensile dello 0,7% ed immersi per 2 ore in una miscela 1:1 (volumetrica) di toluene ed isoottano addizionata del 15% di alcool meti- 5 lieo. tractions are carried out according to the ASTM D 638 method on samples previously subjected to a tensile deformation of 0.7% and immersed for 2 hours in a 1: 1 (volumetric) mixture of toluene and isooctane with the addition of 15% medium alcohol .
Si rileva quindi la ritenzione percentuale del carico di rottura riferita al campione non immerso. The percentage retention of the breaking load referred to the non-immersed sample is therefore noted.
