<P>PROBLEM TO BE SOLVED: To provide a floor material excellent in flame retardancy that hardly generates harmful gases in combustion, excels in combustion safety, and produces less smoke. <P>SOLUTION: A floor material 10 of the present invention comprises at least substrate layers 1 and 2, and a backing layer 3 stacked on the lower surface side of the substrate layer. The substrate layers 1 and 2 each comprises 5 to 40 pts. mass of red phosphorus, 3 to 20 pts. mass of laminar silicate, and 15 to 50 pts. mass of scale-like filler, and 100 to 230 pts. mass of metal hydroxide relative to 100 pts. mass of a resin with no chlorine atoms in the chemical structure. The backing layer 3 comprises a resin composition containing 1 to 5 pts. mass of laminar silicate relative to 100 pts. mass of the resin with no chlorine atoms in the chemical structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
