Title: Thermosetting resin
Inventor: ISHIKAWA GENICHI
IPC: C08L67/00
Filed: 1979-09-18
Abstract: PURPOSE: To provide a thermosetting resin of which the adhesiveness with a grinder, the mutual adhesiveness of ground products and the dispersibility of ground products are improved, by adding a filler for a molding material to a precondensate of a thermosetting resin and molding the obtained mixture into a solid state.  
     CONSTITUTION: A filter for a molding material is added to a precondensate of a thermosetting resin and the obtained mixture is molded into a solid state. A mixing ratio of the precondensate of the thermosetting resin and the filler for the molding material is pref. regulated so as to include the filler in an amount of 20W80wt% against the total mixture. If the adding amount thereof is below 20wt%, the adhesiveness becomes higher and, if the adding amount thereof exceeds 80wt%, the dispersibility is lowered. As the precondensate of the thermosetting resin, a phenol resin, a urea resin, a melamine resin, a xylene resin, an unsaturated polyester resin and modified resins thereof are designated. As the filler for the molding material, a wood powder or a clay is pref. used against a phenol resin, a pulp or an asphalt against a urea resin and calcium carbonate or silica against an unsaturated polyester resin.
