Abstract
U proizvodnji sportske obuće koriste se različiti materijali, od tkanine do kože. Poliuretan je materijal koji je razvijen 30-ih godina 20. st. i u industriji sportske obuće koristi se za izradu uložaka i đonova. Postoje dva tipa PU đonova ovisno o tipu poliola ( polieter i poliester poliol) i diizocijanata (aromatski i cikloalifatski diizocijanat). U ovom radu su pretpolimernim postupkom sintetizirani PU elastomeri na osnovi aromatskog diizocijanata, (MDI) i cikloalifatskog diizocijanata (H12MDI) uz i 1,4-butandiol kao produživač lanca, kao meki segment korišten je polikaprolakton (PCL). Istražena su toplinska svojstva PU elastomera primjenom tehnike diferencijalne pretražne kalorimetrije (DSC) te mehanička svojstva. Rezultati pokazuju da se vrijednosti staklišta (Tg) pomiču se prema višim temperaturama s povećanjem udjela tvrdog segmenta. Veću kristalnost imaju PU elastomeri s aromatskim tipom diizocijanata. Kod PU elastomera s većim udjelom tvrdog segmenta dobivene su veće vrijednosti prekidne čvrstoće.
Abstract (english)
Different materials, from fabric to leather, were used insports footwear production. Polyurethane is material which was developed in 1930s and in the sports footwear industry PU is used to make insoles and shoe soles. There are two types of PU soles based on polyol (polyether and polyester polyol) and type of diisocyanate (aromatic and cycloaliphatic diisocyanate). In this work PU elastomers based on aromatic (MDI) and cycloaliphatic (H12MDI) diisocyanate with 1,4-butanediol (BDO) as chain extender and polycaprolactone (PCL) as soft segment were synthesized by a prepolymer method. The thermal and mechanical properties of PU elastomers were investigated using differential scanning calorimetry (DSC) and tensile strength test. The Tg increased as the hard segment content increased. PU elastomers based on aromatic diisocyanate show the higher degree of crystalization. The PU elastomers with the higher hard segment content show better mechanical properties .
