FIELD: fire safety.
SUBSTANCE: invention relates to panels with fire-protective properties. Panel (22) includes metal coating (12, A), insulating layer (D) of a foamed material and at least one fire protection layer (B, C) between metal coating (12, A) and insulating layer (D) of a foamed material. Fire protection layer (layers) (B, C) contains a dispersion of foamed graphite in polyurethane/polyisocyanurate polymer matrix with the isocyanate index of 1.8 and more.
EFFECT: method of making panel (22) includes provision of first metal coating (12, A) with at least one fire protection layer (B, C), application of insulating layer (D) of a foamed material in the form of a liquid reaction mixture on fire protection layer (layers) (B, C) and application of second metal coating (20, A) on insulating layer (D) of a foamed material.
