Ispitivanje mehaničkih svojstava regranulata PVC-a sa dodatkom plastifikatora iz otpadnog PET-a

Abstract

Predmet ovog istraživanja je postupak proizvodnje regranulata polivinil hlorida (PVC) korišćenjem plastifikatora sintetisanog iz recikliranog poli(etilen tereftalata) (PET). Na ovaj način je sintetisan plastifikator koji ne predstavlja rizik po zdravlje ljudi i životnu sredinu u skladu sa prinicima hemijskog lizinga i zelene hemije. Dobijeni plastifikator je okarakterisan primenom elementalne analize, FTIR, i NMR spektroskopije i određivanjem hidroksilnog i kiselinskog broja. Ispitivana su mehanička svojstva materijala dobijenih na bazi recikliranog PVC i plastifikatora iz PET-a prema standardnim metodama.

The subject of this research is the production process of polyvinyl chloride (PVC) regranulate using a plasticizer synthesized from recycled poly(ethylene terephthalate) (PET). In this way, a plasticizer was synthesized that does not pose a risk to human health and the environment in accordance with the principles of chemical leasing and green chemistry. The obtained plasticizer was characterized using elemental analysis, FTIR, and NMR spectroscopy and determination of hydroxyl and acid number. The mechanical properties of materials obtained on the basis of recycled PVC and plasticizers from PET were tested according to standard methods.
