Abstract

A process for manufacturing nonwoven materials such as floor or wall coverings from natural or synthetic oils and natural or synthetic elastomers is carried out in two reaction phases. In the first reaction phase, a mixture of a stand oil or an equivalent synthetic polymer oil is homogenized with fillers and partially polymerized and partially crosslinked at high temperature to form an intermediate product I. The ground intermediate product I is then homogenized with a natural or synthetic elastomer, in particular natural rubber, fillers and a peroxide and crosslinked and polymerized at a high temperature. The process is suitable for manufacturing homogeneous and possibly marbled floor coverings based on natural materials and processing outstanding physical and optical properties.
