FIRE BARRIER COMPOSITION

摘要

A fire barrier composition suitable for high temperature fires is based on a blend of heat-stable solid inorganic material, fusible solid inorganic material and binder matrix material for the composition ingredients. Advantageously the composition, when subjected to fire temperatures, undergoes sequential changes with increasing temperature, comprising: the binder matrix material commences to carbonise or otherwise deteriorate; the fusible inorganic material fuses sufficiently to bond the heat-stable inorganic material in coherence before the binding effect of the matrix material has completely diminished; and then the fusible inorganic material re-solidifies to provide a solid, hard, insulating, fire-barrier compound.
