发明名称 Floor-covering material using phenol composite resin
摘要 Disclosed is a floor-covering material, in which a phenol composite resin comprising phenol resin of resorcinol-formaline and polyurethane resin is incorporated with paper and dried, to form a prepreg, which is then thermally compressed to the upper side of a PVC base or a waterproof plywood layer, yielding a transparent protective layer and a shaping layer. In the flooring material, the transparent layer and the shaping layer are made of phenol composite resin, and thus low in heat- and moisture-distortion, with no curling. Further, since a surface layer of the floor-covering material is hardly distorted by heat, a balance layer for the suppression of such distortion is not additionally required.
