Abstract
Sposób otrzymywania biodegradowalnej folii na bazie pochodnych polisacharydowych, wykorzystujący proces sieciowania w obecności plastyfikatora, charakteryzuje się tym, że sieciowaniu wielokarboksylowym środkiem sieciującym poddaje się mieszaninę zawierającą karboksymetyloskrobię i karboksymetylocelulozę w roztworze wodnym. Zawartość karboksymetyloskrobi w mieszaninie wynosi 10 - 90% wagowych. Można także stosować mieszaninę zawierającą skrobię, przy czym wówczas zawartość skrobi w mieszaninie wynosi od 10 do 90% wagowych. Stosuje się karboksymetyloskrobię o stopniu podstawienia od 0,15 do 0,90, zaś karboksymetylocelulozę o stopniu podstawienia od 0,5 do 2,3. Wielokarboksylowy środek sieciujący stosuje się w ilości od 15 do 70 części wagowych na 100 części wagowych suchej mieszaniny polisacharydów. Jako wielokarboksylowy środek sieciujący stosuje się kwas cytrynowy, kwas winowy, kwas adypinowy, kwas maleinowy, kwas fumarowy. Sieciowanie można prowadzić w obecności od 1 do 15 części wagowych napełniacza mineralnego lub naturalnego na 100 części wagowych suchej mieszaniny polisacharydów. Jako napełniacz mineralny stosuje się montmorylonit lub kaolin, zaś jako napełniacz naturalny stosuje się celulozę o strukturze włóknistej lub mikrokrystalicznej. Folia biodegradowalna na bazie pochodnych polisacharydowych, charakteryzuje się tym, że stanowi produkt sieciowania wielokarboksylowym środkiem sieciującym mieszaniny zawierającej karboksymetyloskrobię i karboksymetylocelulozę w roztworze wodnym.The method of obtaining a biodegradable film based on polysaccharide derivatives, using the cross-linking process in the presence of a plasticizer, is characterized in that cross-linking with a polycarboxylic cross-linking agent is applied to a mixture containing carboxymethyl starch and carboxymethyl cellulose in an aqueous solution. The content of carboxymethyl starch in the mixture is 10-90% by weight. It is also possible to use a starch-containing mixture, in which case the starch content of the mixture is from 10 to 90% by weight. A carboxy methyl starch with a degree of substitution of 0.15 to 0.90 and a carboxymethyl cellulose with a degree of substitution of 0.5 to 2.3 are used. The polycarboxylic crosslinker is used in an amount of 15 to 70 parts by weight per 100 parts by weight of the dry polysaccharide mixture. Citric acid, tartaric acid, adipic acid, maleic acid, fumaric acid are used as the polycarboxylic cross-linking agent. Crosslinking can be carried out in the presence of 1 to 15 parts by weight of mineral or natural filler per 100 parts by weight of the dry polysaccharide mixture. Montmorillonite or kaolin are used as the mineral filler, and cellulose with a fibrous or microcrystalline structure is used as the natural filler. The biodegradable film based on polysaccharide derivatives is characterized by the fact that it is a cross-linking product of a polycarboxylic cross-linking agent of a mixture containing carboxymethyl starch and carboxymethyl cellulose in an aqueous solution.
