Abstract

Przedmiotem zgłoszenia jest biodegradowalny kompozyt, według zgłoszenia, który charakteryzuje się tym, że, zawiera od 55 do 85 cz. wag. poli(kwasu 3-hydroksymasłowego-co-3-hydroksywalerianowego) oraz od 15 do 45 cz. wag. napełniacza w postaci zmielonych łusek gryczanych, przy czym zmielone łuski gryczane mają wielkość cząstek wynoszącą od 1 µm do 100 µm. Zgłoszenie obejmuje także sposób otrzymywania biodegradowalnego kompozytu, według zgłoszenia, który charakteryzuje się tym, że miesza się od 55 do 85 cz. wag. poli(kwasu 3-hydroksymasłowy-co-3-hydroksywalerianowy) oraz od 15 do 45 cz. wag. napełniacza w postaci zmielonych łusek gryczanych o wielkości cząstek wynoszącej od 1 µm do 100 µm, a następnie mieszaninę suszy się w temperaturze co najwyżej 90°C, po czym mieszaninę podaje się do wytłaczarki ślimakowej i wytłacza się ją, a następnie wytłoczyny granuluje się. Przedmiotem zgłoszenia jest również sposób wielokrotnego przetwarzania wyrobu z biodegradowalnego kompozytu, według zgłoszenia, który charakteryzuje się tym, że wyrób uzyskany w procesie wtryskiwania z biodegradowalnego kompozytu zawierającego od 55 do 85 cz. wag. poli(kwasu 3-hydroksymasłowego-co-3-hydroksywalerianowego) oraz od 15 do 45 cz. wag. napełniacza w postaci zmielonych łusek gryczanych mieli się, po czym uzyskany granulat suszy się, a następnie uplastycznia się w  temperaturze z przedziału od 170 do 190°C oraz formuje się wyrób.The subject of the application is a biodegradable composite, according to the application, which is characterized in that it contains from 55 to 85 parts of weights poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) and from 15 to 45 p. weights a filler in the form of ground buckwheat hulls, wherein the ground buckwheat hulls have a particle size of 1 Pm to 100 Pm. The application also includes a method for obtaining a biodegradable composite, according to the application, which is characterized in that 55 to 85 parts of weights poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) and from 15 to 45 p. weights a filler in the form of ground buckwheat hulls with a particle size of 1 µm to 100 µm, and then the mixture is dried at a temperature of at most 90°C, after which the mixture is fed into a screw extruder and extruded, and then the extrudate is granulated. The subject of the application is also a method of repeated processing of a product made of biodegradable composite, according to the application, which is characterized in that the product obtained in the injection process from a biodegradable composite containing from 55 to 85 parts of weights poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) and from 15 to 45 p. weights the filler in the form of ground buckwheat hulls is ground, then the obtained granulate is dried, and then plasticized at a temperature in the range of 170 to 190 ° C and a product is formed.
