Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania hydrożelowego materiału opatrunkowego na bazie polimeru naturalnego - alginianu sodu i polimeru syntetycznego - poli(alkoholu winylowego), wzbogaconego ekstraktem lub sokiem z Aloe vera, polega na tym, że roztwór alginianu sodu, o stężeniu od 1,0 do 2,5% wag., w ilości od 10 do 75% obj. w stosunku do bazowej kompozycji (to jest mieszaniny składającej się z alginianu sodu, poli(alkoholu winylowego) i ekstraktu lub soku z Aloe vera), łączy się w temperaturze otoczenia, przy ciągłym mieszaniu, z wodnym roztworem poli(alkoholu winylowego), o stężeniu od 5,0 do 12,5% wag., w ilości od 10 do 70% obj. oraz z 2% wag. roztworem ekstraktu lub soku Aloe vera, w ilości od 5 do 25% obj. bazowej kompozycji, po czym do ujednorodnionej mieszaniny wprowadza się, przy ciągłym mieszaniu, czynnik sieciujący, którym jest diakrylan poli(glikolu etylenowego) w ilości od 6,0 do 10% obj., i ogrzewa całość do temperatury 68 do 72°C, po czym wprowadza się inicjator, którym jest roztwór 1% wag. nadsiarczanu amonu, w ilości od 0,8 do 4,2% obj. bazowej kompozycji, a następnie dokładnie wymieszaną kompozycję poddaje się reakcji sieciowania w temperaturze od 65 do 80°C przez 60 do 120 minut, zaś po tym czasie przeprowadza się reakcję dosieciowania w temperaturze pokojowej, przez 24 do 48 godzin.The subject of the application is a method of obtaining a hydrogel dressing material based on a natural polymer - sodium alginate and a synthetic polymer - poly (vinyl alcohol), enriched with Aloe vera extract or juice, consists in the fact that a sodium alginate solution with a concentration of 1.0 to 2 % 5 wt.%, In an amount of 10 to 75 vol.%. with the base composition (i.e. a mixture consisting of sodium alginate, polyvinyl alcohol and Aloe vera extract or juice), combine at ambient temperature, with continuous stirring, with an aqueous solution of polyvinyl alcohol with a concentration of % 5.0 to 12.5% by weight, in an amount of 10 to 70% vol. and with 2 wt. Aloe vera extract or juice solution in an amount of 5 to 25% vol. of the base composition, and then the cross-linking agent, which is poly (ethylene glycol) diacrylate in an amount of 6.0 to 10 vol.%, is introduced into the homogenized mixture, under constant stirring, and heated to 68 to 72 ° C, then whereby the initiator, which is a 1% by weight solution, is introduced. ammonium persulfate, in an amount of 0.8 to 4.2 vol. of the base composition, and then the thoroughly mixed composition is crosslinked at 65 to 80 ° C for 60 to 120 minutes, followed by a crosslinking reaction at room temperature for 24 to 48 hours.
