Flame retarders of polymeric materials
Winkler, David ; Poláček, Petr (referee) ; Kučera, František (advisor)
Bachelor thesis focuses on the study of expanded graphite as flame retardant added to low density polyethylene and it´s potential synergistic effect with ammonium polyphosphate. Additive and non-additive dog-bone samples were prepared by compounding and injection. Crystalization, melting point and thermal decomposition of the samples were monitored by TGA and DSC thermal analysis methods. The effect of expanded graphite on the mechanical proporties of the materiál was monitored by a tenssile test. The effect of expanded graphite as a flame retardant and its synergistic effect with ammonium polyphosphate was confirmed by a flame test in the horizontal position of the sample.
