Abstract: The invention relates to a halogen-free flameproof mesh sheet for use outdoors. The flameproof sheet contains a flame retardant which does not have an increase in viscosity during storage, has excellent gloss and flexibility, and does not generate harmful halogen gas at the time of combustion. A mesh sheet woven out of a coated yarn, typically a multifilament fiber, is impregnated with the flame retardant and heat treated. The fabric is impregnated with the flame retardant such that 60-350 parts by weight of the flame retardant is contained with respect to 100 parts by weight of the mesh sheet fabric. The flameproof mesh sheet are suitable for use in building construction and is suitable for outside exposure for extended lengths of time.
Abstract: A flame retardant including red phosphorus in an amount of 1.5 to 15 parts by weight and an ammonium polyphosphate compound in an amount of 10 to 70 parts by weight, based on 100 parts by weight of the solid content of an aqueous dispersion of an ethylene-vinyl acetate-acrylate copolymer having an ethylene content of 2 to 30 wt %, a vinyl acetate content of 40 to 88 wt %, an acrylate content of 10 to 50 wt % and a resin solid content of 35 to 75 wt %. The flame retardant is useful to flameproof mesh sheets.
