Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania rury z tworzywa biodegradowalnego, która po krótkoterminowym użytkowaniu ulega biodegradacji w warunkach kompostowania przemysłowego. Sposób polega na tym, że 100,0 części wagowych alifatycznego poliestru biodegradowalnego, korzystnie polilaktydu (PLA) lub jego analogu - poli(kwasu mlekowego) (też o symbolu PLA), miesza się w mieszalniku z biodegradowalnym modyfikatorem udarności w ilości od 0,1 do 25,3 części wagowych, korzystnie od 1,0 do 11,2 części wagowych, stanowiącym biodegradowalny alifatyczno-aromatyczny ko-poliester, korzystnie poli(adypinian-co-tereftalan butylenu) (PBAT) lub kopolimer etylenu i akrylanu etylu, albo liniowy elastomer akrylowy na osnowie polilaktydu lub jego analogu - poli(kwasu mlekowego), w tym zawierający ugrupowanie epoksydowe oraz z dodatkowymi biodegradowalnymi składnikami barwiącymi w ilości od 0,1 do 1,3 części wagowych, którymi są barwniki białe oraz czarne, w obu przypadkach na osnowie polilaktydu lub jego analogu — poli(kwasu mlekowego), po czym tak przygotowaną mieszaninę niepołączonych w masie składników wprowadza się do leja zasypowego wytłaczarki ślimakowej, w której układzie uplastyczniającym bez odgazowania, wszystkie składniki poddaje się uplastycznieniu i ujednorodnieniu, a następnie tak ujednorodnioną i uplastycznioną mieszaninę przetłacza się do głowicy wytaczarskiej formującej kształt rury, którą w dalszej kolejności kalibruje się, po czym tak wytworzoną rurę intensywnie chłodzi się, a następnie tnie się na odcinki o zadanej długości.The subject of the application is a method of producing a pipe made of biodegradable plastic, which, after short-term use, biodegrades under industrial composting conditions. The method consists in mixing 100.0 parts by weight of aliphatic biodegradable polyester, preferably polylactide (PLA) or its analogue - poly(lactic acid) (also with the symbol PLA), with a biodegradable impact modifier in an amount of 0.1 up to 25.3 parts by weight, preferably from 1.0 to 11.2 parts by weight, being a biodegradable aliphatic-aromatic co-polyester, preferably poly(butylene adipate-co-terephthalate) (PBAT) or a copolymer of ethylene and ethyl acrylate, or linear acrylic elastomer based on polylactide or its analogue - poly(lactic acid), including one containing an epoxy group and with additional biodegradable coloring ingredients in an amount from 0.1 to 1.3 parts by weight, which are white and black dyes, in both cases based on polylactide or its analogue - poly(lactic acid), then the mixture of ingredients not combined in the mass is then introduced into the hopper of a screw extruder, in which the plasticizing system without degassing allows all ingredients to be plasticized and homogenized, and then homogenized and plasticized the mixture is forced into the boring head forming the shape of a pipe, which is then calibrated, after which the pipe thus produced is intensively cooled and then cut into sections of a given length.
