Abstract
Sposób wytwarzania kompozycji polimerowej w procesie wtryskiwania mikroporującego charakteryzuje się tym, że do układu uplastyczniającego wtryskarki posiadającego cztery strefy grzejne, zasypuje się mieszaninę polipropylenu w ilości od 87,5% do 93,5%, korzystnie 90,0%, środka mikroporującego w postaci mikrosfer o egzotermicznej charakterystyce rozkładu w ilości od 1,5% do 2,5%, korzystnie 2,0% oraz mikrocząstek żelaza w postaci proszku w ilości od 5% do 10%, korzystnie 8%, po czym nagrzewa się powstałą mieszaninę do temperatury w strefie pierwszej 200°C, w strefie drugiej 210°C, w strefie trzeciej 220°C, w strefie czwartej 230°C, następnie wtryskuje się mieszaninę w czasie 5 s do formy wtryskowej o temperaturze 25°C pod ciśnieniem 100 MPa, po czym chłodzi się mieszaninę w formie wtryskowej w czasie 25 s.The method of producing a polymer composition in the process of microcellular injection molding is characterized by the fact that a mixture of polypropylene in the amount of 87.5% to 93.5%, preferably 90.0%, of a microporous agent in the form of microspheres is poured into the plasticizing system of the injection molding machine having four heating zones. with exothermic decomposition characteristics in the amount of 1.5% to 2.5%, preferably 2.0%, and iron microparticles in the form of powder in the amount of 5% to 10%, preferably 8%, after which the resulting mixture is heated to a temperature of in the first zone 200°C, in the second zone 210°C, in the third zone 220°C, in the fourth zone 230°C, then the mixture is injected for 5 s into the injection mold at the temperature of 25°C under the pressure of 100 MPa, and then the mixture in the injection mold is cooled for 25 s.
