Abstract
Cilj ovog rada bio je odrediti vrijeme geliranja uzoraka sastavljenih od različitih epoksidnih smola i umreživala. Osim toga, zadatak je bio odrediti primjenjivost metoda za laboratorijske vježbe. Kao smole korištene su DGEBA i komercijalna (Presto) smola, a kao umreživala amini etilendiamin (EDA) i Jeffamine D400 te komercijalno (Presto) umreživalo. Metode korištene za određivanje vremena geliranja su diferencijalna pretražna kalorimetrija, test izvlačenja niti te praćenje promjene temperature uzorka s vremenom u izoliranom sustavu. Rezultati su pokazali da najbrže geliraju uzorci u kojima je kao umreživalo korišten EDA te da se rezultati općenito najbrže dobivaju praćenjem geliranja u izoliranom sustavu. Nijedna od metoda nije primjenjiva za laboratorijske vježbe.
Abstract (english)
The purpose of this work was to determine the gelation time of samples composed of different epoxy resins and crosslinkers. Besides, the purpose was to determine applicability of the methods for laboratory exercises. DGEBA and commercial (Presto) resin were used as resins, while amines ethylenediamine (EDA) and Jeffamine D400, as well as commercial (Presto) crosslinker were used as crosslinkers. Methods used for determination of gel-time were differential scanning calorimetry, thread pull-out test and monitoring the temperature change of the sample with time in an isolated system. The results showed that the samples in which EDA was used as crosslinker gel the fastest, and that the results in general are obtained the fastest by monitoring the gelation in an isolated system. None of the methods are applicable for laboratory exercises.
