Method of making shaped articles from fibers bonded with oil-resistant synthetic rubber
Abstract
Abstract SHAPED ARTICLES, SUCH AS SHEETS, MADE OF FIBERS BONDED TOGETHER BY AN OIL-RESISTANT SYNTHETIC RUBBER, E.G., GRN RUBBER, ARE FORMED BY WORKING A DOUGH CONTAINING THE FIBERS AND RUBBER INTO THE REQUIRED SHAPE WHILE EVAPORATING SOLVENT. THE DOUGH IS PREPARED BY MIXING THE FIBERS, PLUS OTHER RUBBER COMOUNDING MATERIALS SUCH AS VULCANIZING AGENTS, WITH THE OIL-RESISTANT RUBBER THAT HAS BEEN PREVIOUSLY SOLVATED BY SOAKING FOR AT LEAT SEVERAL HOURS IN AN ORGANIC SOLFTENING LIQUIED DILUENT IN WHICH THE RUBBER IS AT LEAST SUBSTANIALLY INSOLUBLE, AND THEN WORKING THE MIXTURE INTO A UNIFORM SOFTENED MASS BY AGITION. SHEETS FORMED FROM THE DOUGH MAY TYPICALLY BE USED FOR GASKETS, FLANGE PACKING, AND THE LIKE.
