Abstract

PURPOSE: To provide a base cement which is not dangerous in transportation, by kneading a powdery cement material comprising a novolak-type thermosetting resin, a natural resin, a hardener and an inorganic filler, together with a solvent.
CONSTITUTION: A novolak-type thermosetting resin such as phenol resin, aklylphenol resin or polyimide resin is pulverized by a victory mill or the like. A natural resin such as pine resin or shellac is also pulverized by a victory mill or the like. These powdery resins are mixed with a powdery hardener such as hexamethylenetetramine and an inorganic filler such as calcium carbonate, thereby obtaining a powdery cement material. When this material is put in use, it is kneaded with a solvent such as ethanol or methyl ethyl ketone to obtain a base cement for an electric bulb.
