Abstract

Described herein is flooring formed of an eco-friendly material, where the flooring has excellent heat resistance, durability, abrasion resistance and dimensional stability, and is formed of a non-PVC material and thus is recyclable via an extrusion processing at the time of disposal after use. Specifically, eco-friendly flooring is described in which a coating layer, an overlayer having ionomers, a printing layer, at least one middle layer, and at least one underlayer are laminated in order, where the overlayer of the flooring has ionomers, at least one of the middle layer and the underlayer has a thermoplastic polyolefin-based resin, a styrene-based resin, oil, and a filler, the thermoplastic polyolefin-based resin is contained in an amount of 50 to 150 parts by weight with respect to 100 parts by weight of the styrene-based resin, and the styrene-based resin may contain 25 to 45% styrene.
