摘要
The present invention is concerned with a new method for preparing a fibrous product containing cellulosic fibers and which is useful, in particular in lieu of asbestos, in the field of covering panels such as for instance wall and floor covering panels. Said method comprises the formation of a sheet according to a paper-making technique from an aqueous suspension comprising: slightly refined cellulosic fibers having a Schopper-Riegler degree comprised between 15 and 35, in association, if the occasion arises, with non-cellulosic fibers, an inorganic flocculating agent, an organic polymeric binder, and an inorganic filler, and the squeezing of the wet drained sheet under a linear load of 5 to 35 kg/cm, then the drying of the squeezed sheet. The sheet thus obtained is, if the occasion arises, subjected to a mechanical and/or chemical complementary treatment. The invention is also concerned with the sheet obtained according to this method, as a new industrial product.
