Abstract

Sposób modyfikacji zywicy epoksydowej zwiazkami epoksydowymi otrzymanymi z odpadowego poli(tereftalanu etylenu) polega na tym, ze do zywicy epoksydowej otrzymanej na bazie surowców petrochemicznych dodaje sie zywice epoksydowa zsyntezowana na bazie produktów degradacji odpadowego poli(tereftalanu etylenu) bisfenolami w ilosci od 1 do 30 czesci wagowych na 100 czesci wagowych zywicy na bazie surowców petrochemicznych i od 0 do 5 czesci wagowych srodka odpieniajacego na 100 czesci wagowych zywicy i modyfikatora, przy czym zywice na bazie produktów degradacji PET ogrzewa sie wstepnie w temperaturze 25-100°C przez okres od 5 do 30 minut, a kompozycje miesza sie i ogrzewa sie w temperaturze 25-100°C przez okres od 5 minut do 2 godzin i nastepnie ogrzewa sie w temperaturze 50-100°C pod zmniejszonym cisnieniem przez okres od 5 do 30 minut.The method of epoxy resin modification with epoxy compounds obtained from waste poly (ethylene terephthalate) consists in adding an epoxy resin based on petrochemical raw materials to the epoxy resin, synthesized on the basis of the degradation products of waste poly (ethylene terephthalate) with bisphenols in the amount of 1 to 30 parts weight per 100 parts by weight of resin based on petrochemical raw materials and 0 to 5 parts by weight of defoamer per 100 parts by weight of resin and modifier, the resins based on PET degradation products are preheated at 25-100 ° C for a period of 5 to 30 minutes, and the compositions are mixed and heated at 25-100 ° C for 5 minutes to 2 hours and then heated at 50-100 ° C under reduced pressure for 5 to 30 minutes.
