PIECE SOUPLE A PROPRIETES COUPE-FEU
L'invention porte principalement sur une pièce souple à propriétés coupe-feu, caractérisée en ce qu'elle comporte une nappe (3,3a) d'éléments fibreux inorganiques et isolants (2) qui est au moins partiellement enduite et au moins partiellement imprégnée d'un gel aqueux (4), formant ainsi une nappe gélifiée (5,5a). La pièce souple de l'invention trouve notamment application dans la protection au feu des chemins de câbles électriques.
The invention relates mainly to a flexible part with firebreak properties to protect any mechanical, structural or electrical element against an excessive temperature increase, which is essentially characterised in that it includes at least: a layer (3, 3a) of inorganic, insulating fibrous elements (2); an aqueous gel (4) arranged immediately next to said layer (3); and a sealed enclosure (6, 7) which insulates at least the aqueous gel (4) from the environment, so that upon exposure to excessive temperatures, the aqueous gel (4) is at least partially impregnated in the fibre layer (3) so as to delay the temperature increase thereof. The flexible part of the invention can be used mainly in the fire protection of electrical raceways.
