A component, such as a title or a floorboard, has electro-conductive properties for producing a floor covering, or a similar system, in particular for a medium sensitive to static electricity. The component includes a stack of layers integral with one another and including successively: a wearing layer of plastic consisting of granules of conductive material spread out through the thickness of said wearing layer, a first textile reinforcing armature, a middle layer of plastic comprising granules of conductive material spread out through the thickness of said middle layer, a second textile reinforcing armature, and an under layer of plastic material consisting of granules of conductive material spread out through the thickness of said under layer.

The present invention relates to a flame-retardant decorative flooring material including a lower layer; a base layer; a printed layer; and a transparent layer sequentially from bottom to top, wherein at least any one of the layers includes a polyvinyl acetal resin. In addition, the present invention relates to a method of manufacturing a flame-retardant decorative flooring material including a lower layer; a base layer; a printed layer; and a transparent layer sequentially from bottom to top, the method including (1) a lower layer preparation step of preparing a lower layer using a composition including 100 parts by weight of a polyvinyl acetal resin and 100 to 400 parts by weight of a filler based on 100 parts by weight of the polyvinyl acetal resin; (2) a base layer preparation step of preparing a base layer composed of glass fiber that is immersed in a PVC sol; (3) a printing step of forming a printed layer by printing a pattern on the base layer or laminating the base layer with a pattern-printed film or paper; (4) a transparent layer preparation step of preparing a transparent layer composed of a transparent PVC film or a PET film; and (5) a lamination step of disposing the base layer including the printed layer formed thereon between the lower layer and the transparent layer and laminating the same.
