Abstract (en)
The invention relates to a flexible, flame-retardant composite material comprising:- a fabric layer; and- at least one impregnated or coated Polyvinyl Butyral (PVB) coating layer, which is integral with said fabric layer; the PVB coating layer containing 20 to 60% by weight of PVB, at least one plasticizer in an amount of 5 to 40% by weight of the coating layer, and a mixture of antimony trioxide Sb<sub>2</sub>O<sub>3</sub> and at least one halogenated organic compound as flame retardant in a total amount of 5 to 45% by weight with respect to the coating layer, and in a ratio of 0.1 to 5 part of antimony trioxide Sb<sub>2</sub>O<sub>3</sub> per part of halogenated organic compound.The invention also relates to the manufacturing method thereof, comprising an impregnation or coating of a water-based dispersion of PVB onto the fabric layer, and a further curing.
