Title
(EN) FLOOR COVERING WITH FIREPROOF WEAR LAYER
(FR) REVETÊMENT DE SOL À COUCHE D'USURE IGNIFUGÉE
Abstract
(EN) The present invention relates to a multi-layer floor covering comprising, from the base to the top of the covering: - a back layer A, - a decorative layer B, and - a surface layer C, the decorative layer B being advantageously in the form of a printed substrate or an ink layer printed on the back layer A or on the back of the surface layer C, the surface layer C comprising: - a polymer matrix comprising polyvinyl chloride and - a mineral filler comprising hydrotalcite, the hydrotalcite being used as fireproofing and having a rate of incorporation, by weight, in the polymer matrix that is greater than or equal to 3%, preferably greater than or equal to 5%.
(FR) La présente invention concerne un revêtement de sol multicouche comprenant, depuis la base vers le sommet dudit revêtement : - une couche d'envers A, - une couche de décor B, - une couche de surface C, dans lequel : la couche de décor B se présente avantageusement sous la forme d'un support imprimé ou d'une couche d'encre imprimée sur la couche d'envers A ou sur l'envers de la couche de surface C, la couche de surface C comprend : - une matrice polymère comprenant du polychlorure de vinyle, et - une charge minérale comprenant de l'hydrotalcite, l'hydrotalcite étant utilisé comme ignifugeant et présentant un taux d'incorporation, en poids, dans la matrice polymère supérieur ou égal à 3%, préférentiellement supérieur ou égal à 5%.
