Phosphorous-containing flame retardant plasticizer based on Cassia fistula seed oil and their application in poly (vinyl chloride) films

摘要: The need for safety and sustainability has prompted the development of flame-retardant bio-based plasticizers from renewable resources. In this study, an efficient phosphorous-containing flame retardant plasticizer (ECFSO-P) for poly(vinyl chloride) (PVC) was synthesized using Cassia fistula seed oil and characterized by fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) and proton nuclear magnetic resonance (1H NMR) spectroscopies. In replace of the dioctyl phthalate (DOP), the ECFSO-P was employed as a flame retardant plasticizer to produce poly(vinyl chloride) (PVC) blends. The PVC blends were prepared using ECFSO-P, DOP, and ECFSO-P + DOP blends as plasticizers. The PVC blends with different concentrations of DOP and ECFSO-P were investigated with thermo-gravimetric analysis (TGA), differential scanning calorimetry (DSC), mechanical properties, fire retardant …
