PURPOSE:To obtain a firmly bonded carbonaceous product in high productivity, by bonding plural molded articles of thermosetting (expanded) resin with an adhesive consisting of a prepolymer of raw material of the resin, a solvent and a curing agent and calcining the bonded articles in a non-oxidizing atmosphere. CONSTITUTION:Plural molded articles of resin and/or expanded resin consisting of the same thermosetting resin (e.g., phenolic resin) are bonded with an adhesive which consists of the same prepolymer (e.g., resol type phenolic resin) as that of raw material of the thermosetting resin, a solvent (e.g., ethanol) and a curing agent (e.g., p-toluenesulfonic acid) and has 50-1,000 cps viscosity (20 deg.C). Then this bonded product is calcined in a non-oxidizing atmosphere and carbonized to give the aimed bonded carbonaceous product. Consequently, the product can be manufactured by a simpler process than a method wherein calcined carbonaceous products are mutually bonded and calcined again. |
