Inorganic flame retardants and their application in composites
 Bergmann, Ondřej ; Kučera, František (referee) ; Poláček, Petr (advisor)
In the first part of this bachelor thesis frequently used fire retardant additives are described as well as their mechanisms of action and the most common methods of flammability characterization. In the second experimental part the influence of two systems, consisting of a matrix and two fillers in different ratios, on viscosity, thermal stability and flammability were examined. Unsaturated polyester resin was used as the matrix. The first filler was always a fire retardant based on aluminium hydroxide, which was combined with the second filler based on either ammonium polyphosphate, or melamine polyphosphate. Viscosity of these samples was determined and casts for further analyses were made. Casts were analysed with thermogravimetric analysis and by flammability tests. Generally, with higher filler content the samples were more viscous, thermally degraded at lower temperatures and had better fire characteristics.
