METHOD OF
MANUFACTURING SEALING INSERTS FROM DISINTEGRATED WASTES
FIELD: rubber industry.
SUBSTANCE: inserts designed to be placed between
parts and blocks of internal combustion engines are manufactured from
disintegrated rubber stopper wastes adding 45-40% binder, in particular crude
nitrile rubber compound. Wastes are ground first to fractions 3-5 mm and the to
fractions 0.3-0.5 mm. Waste-binder mixture is extruded into bundles 3-10 mm long,
which are then molded at 155- 165 C under pressure 20-30 MPa. Thermal
stabilization is finally carried out for 12-24 h at 100-130 C.
EFFECT: increased resistance of inserts and
solved waste disposal problem. 3 tbl
