Abstract
Przedmiotem wynalazku jest sposób wytwarzania wysokonapełnionego kompozytu biodegradowalnego przeznaczonego do otrzymywania w procesie wytłaczania folii płaskich, będących podatnymi na biodegradację w warunkach kompostowania przemysłowego. Nieusieciowany poli(ε-kaprolakton) (PCL) w postaci granulatu o wagowo średnim (MW) ciężarze cząsteczkowym 110 kDa, wprowadza się przy pomocy dozownika wolumetrycznego w ilości od 25% masowych do 75% masowych do pierwszej strefy zasilania układu uplastyczniającego wytłaczarki wraz z dozowaną przez dozownik wolumetryczny naturalną mieszaniną mineralną (NMM) o gęstości 2,4 g/cm3 i wielkości cząstek d50 2,16 µm, zawierającą od 97,5% masowych do 98,4% masowych niemodyfikowanego węglanu wapnia, 0,5% masowych tlenku żelaza na trzecim stopniu utlenienia, 1% masowych węglanu magnezu oraz od 0,1 do 1% masowych dwutlenku krzemu, w takiej ilości aby mieszanina ta stanowiła uzupełnienie 100% masowych przetwarzanego kompozytu, po czym PCL i NMM miesza się w układzie uplastyczniającym i poddaje działaniu sił ścinających, a następnie ujednorodnioną i uplastycznioną mieszaninę odgazowuje się za pomocą odgazowania swobodnego i przetłacza się do głowicy wytaczarskiej, a następnie chłodzi się w wannie z wodą i wytwarza w znany sposób granulat wysokonapełnionego biodegradowalnego tworzywa polimerowego.The subject of the invention is a method for the production of a highly filled biodegradable composite intended for the production of flat films in the extrusion process, which are biodegradable under the conditions of industrial composting. Uncross-linked poly (ε-caprolactone) (PCL) in the form of a weight average (MW) molecular weight (MW) 110 kDa pellet is introduced by means of a volumetric feeder in the amount of 25% by weight to 75% by weight to the first feed zone of the plasticizing system of the extruder along with the dosing through a volumetric injector with a natural mineral mixture (NMM) with a density of 2.4 g / cm3 and a d50 particle size of 2.16 µm, containing from 97.5% by mass to 98.4% by mass of unmodified calcium carbonate, 0.5% by mass of iron oxide in the third oxidation state, 1% by weight of magnesium carbonate and from 0.1 to 1% by weight of silicon dioxide, in such an amount that this mixture constitutes a supplement to 100% by weight of the processed composite, then PCL and NMM are mixed in a plasticizing system and subjected to the action of forces and then the homogenized and plasticized mixture is degassed by free degassing and forced into the boring head, and then cooled in a bathtub with a and produces, in a known manner, granules of a highly filled biodegradable polymer material.
