ABSTRACT:
An improved dimensionally stable backing web is disclosed, especially for resilient flooring product and linoleum, comprising cellulosic fiber, a binder, antioxidant, fungicide and glass fiber, as well as optionally dyes or pigments, surfactants and vulcanizing agents. Also optionally present are calcium silicate mineral fiber or synthetic fiber, such as polyolefin, polyester, nylon, acrylic or modacrylic fiber, a cellulose acetate or mixtures thereof. The binder can be a natural rubber or synthetic rubber latex or mixtures thereof. The synthetic rubber latex is preferably selected from the following: styrene-butadiene; carboxylated styrene-butadiene, polyacrylic ester, polyvinyl acetate; polyisobutylene, a copolymer formed from vinyl acetate monomers and acrylic acid; polychloroprene, acrylonitrile-butadiene or carboxylated acrylonitrile-butadiene; polyurethane; a copolymer of ethylene and vinyl acetate; or other elastomeric copolymers. The glass fiber is dispersed into a slurry which is introduced in manufacturing the backing web by wet web impregnation, dry web impregnation, latex beater deposition, or continuous latex wet-end deposition, preferably by wet web impregnation. The web can be used alone or in combination with one or more surface coatings to form a layered material.
