Abstract

Przedmiotem wynalazku jest sposób wytwarzania materiału termoplastycznego jako filamentu do druku 3D zawierający poli(alkohol winylowy), polikaprolakton oraz chitozan. Sposób polega na tym, że roztwór nasycanego dwutlenkiem węgla chitozanu poddaje się kompatybilizacji do przetwórstwa z surowcami termoplastycznymi poprzez zmieszanie jego z wodnym roztworem hydrolizowanego poli(alkoholu winylowego), o stopniu hydrolizy co najmniej 75%  korzystnie 80%, gdzie udział masowy obu polimerów w odniesieniu do ich bezwodnych form wynosi 1:1. Dalej mieszaninę zamraża się w temperaturze w zakresie od -80°C do -18°C i wysusza sublimacyjne w warunkach ciśnienia w zakresie 0,9 — 6,0 mbar, przy różnicy temperatur pomiędzy kondensatorem liofilizatora a próbą w zakresie od 70°C do 140°C. Wysuszony kompozyt chitozanu i poli(alkoholu winylowego) po rozdrobnieniu miesza się z polikaprolaktonem zaś otrzymany filament poddaje się ekstruzji, korzystnie dwustopniowej.The subject of the invention is a method of producing a thermoplastic material as a 3D printing filament containing polyvinyl alcohol, polycaprolactone and chitosan. The method consists in the fact that the carbon dioxide-saturated chitosan solution is made compatible for processing with thermoplastic raw materials by mixing it with an aqueous solution of hydrolyzed polyvinyl alcohol, with a degree of hydrolysis of at least 75%, preferably 80%, where the mass fraction of both polymers relative to to their anhydrous forms is 1: 1. Further, the mixture is frozen at a temperature in the range of -80 ° C to -18 ° C and freeze-dried under pressure conditions in the range of 0.9 - 6.0 mbar, with the temperature difference between the freeze dryer condenser and the sample in the range of 70 ° C to 140 ° C. The dried composite of chitosan and polyvinyl alcohol, after grinding, is mixed with the polycaprolactone and the obtained filament is subjected to extrusion, preferably in two stages.
