Patent ID: 7015157

Claim:
A non-halogen series floor material, comprising: an intermediate resin layer containing filler, resin (except for amorphous poly α-olefin resin whose number average molecular weight is 20,000 or less) 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 said amorphous poly α-olefin resin being 5 to 40% by weight with respect to entire resin ingredients; a surface resin layer having a thickness of 30 to 1,000 μm integrally formed on an upper surface of said intermediate resin layer, said surface resin layer including no chlorine atom in chemical constitution; and a backing layer integrally formed on a lower surface of said intermediate resin layer, said backing layer being a polypropylene spun bond nonwoven fabric, wherein said surface resin layer is a monolayer structure containing polypropylene resin as a main resin ingredient or a lamination structure in which at least the uppermost surface layer contains polypropylene resin as a main resin ingredient.
