Abstract
An inlaid tile composition and a method for making the composition in which filled colored polymeric chips are uniformly dispersed throughout a filled thermoplastic tile base is disclosed. In an alternative embodiment, colored, coated mineral chips of a mineral such as quartz are uniformly dispersed throughout a filled thermoplastic tile base. The chips are coated by a ceramic technique or with a pigmented polyester or epoxy resin. Alternatively, a mixture of coated mineral chips and partially cross linked resinous chips may be employed. In a further embodiment, additional chips may be spread on the top surface of the formed sheet and pressed in with a roller, prior to the final calendering step. The tile base may contain a lubricant to reduce processing temperatures and shear forces in the intensive mixer.
