Anti-slip Vinyl Flooring and Method For Manufacturing The Same

Abstract

Disclosed is anti-slip vinyl flooring that is capable of forming a concavo-convex portion having a thickness of more than a given value on a PVC surface layer of the vinyl flooring, thus effectively preventing slipping thereon and further ensuring a high degree of dimension stability. The anti-slip vinyl flooring according to the present invention is formed by sequentially laminating a PVC surface layer, a PVC base layer, and a backing layer, from the top thereof, wherein a concavo-convex portion having a thickness in the range of 70 μm to 160 μm is formed on the PVC surface layer.
