Abstract
Przedmiotem zgłoszenia jest polietylen do wytwarzania folii o właściwościach biobójczych i poprawionych właściwościach użytkowych zawierający w % masowych 94 - 99 polietylenu i modyfikator w postaci mieszaniny 1 - 6 haloizytu z dodatkiem 10 - 30 związków miedzi oraz haloizytu z dodatkiem 10 - 30 kwasu itakonowego o powierzchni właściwej BET 39 - 45 m2/g i średniej wielkości porów oznaczonej metodą niskotemperaturowej adsorpcji azotu 120 - 190 nm i jest wytwarzany w procesie jednoetapowym w dwuślimakowej wytłaczarce współbieżnej, gdzie do uplastycznionego polietylenu wprowadza się jednym podajnikiem bocznym uplastyczniony haloizyt zawierający związki miedzi i drugim podajnikiem bocznym haloizyt modyfikowany kwasem itakonowym lub mieszaninę obu haloizytów jednym podajnikiem bocznym, przy czym proces wytłaczania prowadzi się w temperaturze 175 - 220°C, przy szybkości obrotowej ślimaka 300 - 500 min-1. Zgłoszenie obejmuje także sposób wytwarzania folii polietylenowej o właściwościach biobójczych.The subject of the application is polyethylene for the production of films with biocidal properties and improved functional properties, containing in% by weight polyethylene 94 - 99 and a modifier in the form of a mixture of 1 - 6 halloysite with the addition of 10 - 30 copper compounds and halloysite with the addition of 10 - 30 itaconic acid with a specific surface BET 39 - 45 m2 / g and the average pore size determined by the low-temperature nitrogen adsorption method of 120 - 190 nm and is produced in a one-stage process in a co-rotating twin-screw extruder, where plasticized polyethylene is introduced into the plasticized polyethylene with one side feeder, plasticized halloysite containing copper compounds and a second side feeder with itaconic acid or a mixture of both halloysite materials with one side feeder, the extrusion process being carried out at a temperature of 175 - 220 ° C, at a screw speed of 300 - 500 min-1. The application also covers a method of producing a polyethylene film with biocidal properties.
