发明名称 Moisture-resistant fire-retardant decorative floor and wall coverings and process for the manufacture thereof
摘要 Improved moisture-resistant fire-retardant decorative floor and wall covering laminates and a method for making the same are described, having an asbestos backing, an intermediate layer of wood veneer and a face wear-resistant layer of vinyl, through which the decorative wood veneer may be seen. The vinyl wear resistant layer is usually clear and colorless. An optional colored vinyl layer may be laminated between the wood veneer and asbestos layer. The asbestos backing resists moisture penetration and transmits the moisture laterally to the edges of the laminate where it escapes. The asbestos and the vinyl face protect the wood veneer from fire, thus providing a highly fire-retardant and moisture-resistant, but decorative floor and wall covering.
