Abstract
A non-halogen series floor material includes an intermediate resin layer containing filler, resin having no chlorine atom in chemical structure as a primary resin ingredient and amorphous poly α-olefin resin whose number average molecular weight is 20,000 or less. The content of the amorphous poly α-olefin resin is 5 to 40% by weight with respect to entire resin ingredients. On the upper surface of the intermediate resin layer, a surface resin layer having a thickness of 30 to 1,000 μm is integrally formed. The surface resin layer includes no chlorine atom in chemical constitution. On the lower surface of the intermediate layer, a heat shrinkage-characteristic cloth is integrally formed by heating it to form a backing layer. This provides a non-halogen floor material that hardly generates toxic gases at the time of burning, can be manufactured at a low cost and is excellent in wear resistance, stain resistance, dimensional stability and workability.
