Flammability of the Disperse-Filled Polymer Composites
For the purpose of fire safe construction it is necessary to develop and investigate effects of fillers to flammability of building materials, including composite materials with polymer matrix. In present work we demonstrate the results of such investigation. We have examined influence of chemical composition, amount of mineral fillers to flammability, smoke-forming ability and limiting oxygen index of building materials based on different polymer binders. The experimental data indicate that the main parameter which determines the influence of mineral fillers on the flammability of composites is a specific heat absorbed by the filler. The dependence between limiting oxygen index and specific heat of mineral fillers is revealed for composites with epoxy matrices. This dependence is simple and beneficial for practical use.
