The aim of this study was to investigate the effect of boron compounds on fire protection properties of intumescent coating based on ammonium polyphosphate (APP). Three kinds of boron compounds namely boric acid (BA), zinc borate (ZB) and melamine borate (MB) were used. Total amount of flame retardant additive was kept constant at 30 wt%, and boron compounds were used at three concentrations of 1, 3 and 5 wt%. Thermogravimetric analysis (TGA), Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and fire test were conducted for the determining the fire performance of intumescent coating. According to fire test results, BA and MB showed synergistic effect at 1 wt% loading. ZB showed antagonistic effect at all concentrations. Fire protection effect of intumescent coating decreased as the added amount of boron compound increased regardless of boron compound type because of suppression of intumescence.

Use of boron oxide and boric acid to improve flame retardancy of an organophosphorus compound in neat and fiber reinforced polyamide-6 POLAT, Osman; Kaynak, Cevdet (2016-09-01) The aim of this study was to investigate the usability of boron oxide and boric acid to enhance flame retardancy of (aluminum diethyl phosphinate)-type organophosphorus compound in polyamide-6 and its 15 wt% of short (glass fiber)-reinforced composite. Materials were compounded by melt-mixing method via a twin-screw extruder, and the specimens for testing and analyses were shaped by injection and compression-molding. For the neat polyamide-6 specimens, mass loss cone calorimetry analyses indicated that repl...
Effect of microcapsulated red phosphorus on flame retardant, thermal and mechanical properties of thermoplastic polyurethane composites filled with huntite&hydromagnesite mineral ATABEK SAVAŞ, Lemiye; Deniz, Tugba Kaya; Tayfun, Umit; DOĞAN, Mehmet (2017-01-01) The effect of microcapsulated red phosphorus (mRP) was studied on the flame retardant, thermal and mechanical properties of thermoplastic polyurethane (TPU) composites containing Huntite&hydromagnesite (HH). The flame retardant properties of TPU based composites were investigated using limiting oxygen index (LOI), vertical burning test (UL 94), thermogravimetric analysis (TGA) and mass loss calorimeter. The mechanical properties of composites were studied using tensile test and dynamic mechanical analysis (...
Influence of zinc borate on flame retardant and thermal properties of polyurethane elastomer composites containing huntite-hydromagnesite mineral Dike, Ali Sinan; Tayfun, Umit; DOĞAN, Mehmet (2017-11-01) The effect of zinc borate (ZnB) was studied on the flame retardant and thermal properties of thermoplastic polyurethane containing huntite-hydromagnesite. The flame retardant properties of thermoplastic polyurethane-based composites were investigated using limiting oxygen index, vertical burning test (UL 94), thermogravimetric analysis, and mass loss calorimeter. No remarkable effect of ZnB was observed on the flammability properties of composites. UL 94 rating did not change regardless of the added amount ...
Contribution of boron compounds and nanoclays on the flame retardancy of aluminium diethylphosphinate in neat and fiber reinforced polyamide-6 Polat, Osman; Kaynak, Cevdet; Department of Polymer Science and Technology (2014) The main objective of this dissertation was to investigate contribution of three different boron compounds and nanoclays to the flame retardancy of polyamide-6 and its 15 wt% short glass fiber reinforced composite with and without an organophosphorus flame retardant aluminum diethylphosphinate. All material combinations and nanocomposites were compounded by melt mixing method via twin-screw extruder and the specimens for testing and analyses were shaped by injection and compression molding. In the first par...
Effects of nanoclays on the flammability of polystyrene with triphenyl phosphate-based flame retardants Kaynak, Cevdet (SAGE Publications, 2013-07-01) The main purpose of this study is to investigate the effects of nanoclays on the flammability behavior of neat polystyrene and polystyrene compounded with traditional flame retardants triphenyl phosphate and its synergist melamine cyanurate. Nanocomposites were prepared via ultrasound-assisted solution intercalation technique. Dispersion and nanomorphology of nanoclays were investigated through X-ray diffraction analysis and transmission electron microscopy. Thermal stability and flammability behaviors were...
