FREE LAYING FLOOR TILE HAVING PVC BASED BACKING MATERIAL FOR PREVENTING TILE FROM SLIPPING PROVIDED ON BACK SURFACE THEREOF

摘要

A loose-lay floor tile which has on a back face a nonskid backing material obtained by solidifying a paste sol containing a plasticizer and one of polyvinyl chloride, copolymers of vinyl chloride and vinyl acetate and mixtures of polyvinyl chloride and polyvinyl acetate. Drawbacks of conventional acrylic mechanically foamed materials such as water absorption, resistance to water, resistance to alkali and strength of a foamed material are improved.
