  • Publication number: 20090061168
    Abstract: A method for manufacturing a floor covering including forming a printing layer and a transparent film layer sequentially on a base layer made of polyvinyl chloride (PVC) as a main ingredient, forming a balance layer underneath the base layer, and forming a plurality of foam layers arranged in a row to be equally spaced apart from each other underneath the balance layer is disclosed. The floor covering manufactured by the above has a slip-resistant effect on the floor of a building during the construction. Thus, the construction is carried out without an additional adhesive, and the use amount of the adhesive may be significantly reduced, if being used. Moreover, the floor covering can be replaced immediately without the finishing process, as well as, the recovered floor covering can be recycled since there is no damage thereon. Thus, an eco-friendly construction becomes possible.
