SYNTHETIC RESIN COMPOSITION FOR MOLDING WITH GOOD PHYSICOCHEMICAL PROPERTIES

摘要

Synthetic resin composition for molding, having good physicochemical properties, were prepd. by mixing 20-30 wt. % novolac-type carbolic acid resin with hydrate porous aluminium silicate as filler. Thus, 250-300kg novolac-type carbolic acid resin was mixed with 750-700kg hydrate aluminium silicate and then mixed with hexamin 14%, magnesium oxide 2%, magnesium stearate 2% (novolac-type carbolic acid resin=100%) at 70-90≦̸C for 15-30min.
