Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania modyfikowanej skrobi termoplastycznej, w którym miesza się skrobię natywną z plastyfikatorem/-ami i wytłacza,  polegający na tym, że w pierwszym etapie skrobię natywna w ilości 60 - 70% mas. homogenizuje się w temperaturze 50 — 80°C z 25 — 35% mas. plastyfikatora i ewentualnie z 0,5 — 5% mas. wielofunkcyjnego modyfikatora stanowiącego glinokrzemian o budowie warstwowo-rurkowej, przeprowadza się w suchą mieszankę z jednoczesnym odprowadzeniem wody, którą w drugim etapie, z pominięciem etapu kondycjonowania, przeprowadza się w stan uplastyczniony i wytłacza z równoczesnym odgazowaniem części lotnych, a następnie granuluje. Zgłoszeniem jest również biodegradowalny kompozyt zawierający w ilości 35 – 55% mas. skrobię termoplastyczną modyfikowaną powyżej ujawnionym sposobem, 20 - 45% mas. biodegradowalny polimer wielkocząsteczkowy oraz ewentualnie 20 — 55% mas. napełniacz pochodzenia naturalnego. Otrzymane kompozyty przeznaczone są do wytwarzania jednorazowego użytku, w tym folii, konwencjonalnymi technikami przetwórstwa tworzyw sztucznych tj. metodą wytłaczania, wytłaczania z rozdmuchiwaniem i wtryskiwania.The subject of the application is a method for producing modified thermoplastic starch, in which native starch is mixed with plasticizer(s) and extruded, in which, in the first stage, native starch in an amount of 60 - 70% by weight. homogenized at a temperature of 50 - 80°C with 25 - 35% by weight. plasticizer and optionally with 0.5 - 5 wt.%. multifunctional modifier, which is an aluminosilicate with a layered and tubular structure, is transformed into a dry mixture with simultaneous drainage of water, which in the second stage, bypassing the conditioning stage, is plasticized and extruded with simultaneous degassing of volatile parts, and then granulated. The application also includes a biodegradable composite containing 35 – 55% by weight. thermoplastic starch modified by the method disclosed above, 20 - 45 wt. biodegradable high-molecular polymer and optionally 20 - 55% by weight. filler of natural origin. The obtained composites are intended for the production of single-use materials, including foils, using conventional plastics processing techniques, i.e. extrusion, extrusion blowing and injection.
