Projekat

Usmerena sinteza, struktura i svojstva multifunkcionalnih materijala (MPNTR - 172057)

Sažetak

U ovom radu prikazana je sinteza alkidnih smola visokih performansi baziranih na otpadnim poli(etilentereftalat) (PET) glikolizatima. PET glikolizati su sintetisani katalitičkom depolimerizacijom sa trimetilolpropanom (TMP) i trimetiloletanom (TME) koji su korišćeni za zamenu polihidroksilne komponente u toku sinteze alkidnih smola. Dobijeni glikolizati i alkidne smole u velikom prinosu su okarakterisane FTIR i 1HNMR spektroskopijom, kiselinskim, jodnim i hidroksilnim brojem. Određena su reološka svojstva sintetisanih alkidnih smola kao što su debljina, athezija, tvrdoća i sjaj i sve sintetisane alkidne smole su pokazale veliku adeziju i tvrdoću i sjaj veći od 98%. Ispitivan je uticaj dodatka modifikovanih silika Aerosil® R380 nanočestica na mehaničke I antikorozivne karakteristike dobijenih nanokompozitnih premaza na bazi alkidnih smola.
