Description

The invention relates to a method for producing a mineral fibre board which comprises a coloured pigment and whose at least one surface is provided with a non-woven coating made of a substantially black material. The inventive method consists in inserting the coating into a board production device, wherein said coating is embodied in the form of a fabric, which is based on a polyester with appropriate weight per unit square, not precoloured and not impregnated or provided with an additional adhesive agent introduced therein for adhering to fibre pads. A coloured mineral wool product provided with the same colour coating produced by the inventive method is also disclosed.

L'invention se rapporte à un procédé de fabrication d'un panneau de fibres minérales, ledit panneau comprenant un pigment coloré et au moins l'une de ses faces étant revêtue d'un revêtement non tissé d'un matériau essentiellement noir. Ledit procédé se caractérise en ce que le revêtement sous la forme d'un voile à base de polyester de grammage approprié est introduit dans l'installation de fabrication des panneaux sans traitement de coloration préalable et sans imprégnation ou introduction de colle supplémentaire pour son adhésion au matelas de fibre. L'invention porte également sur le produit en laine minérale colorée comprenant un revêtement de même couleur, susceptible d'être obtenu par ledit procédé.
