フェノール樹脂、フラン樹脂。To composite the resin, a mixture of resin powder and expanded graphite particles may be molded, but it is easier to work and a uniform product can be obtained by coating or impregnating the expanded graphite molded body with a resin solution. Therefore, it is preferable. The resin used for impregnation may be either a thermosetting resin or a thermoplastic resin, but with thermoplastic resins, the solution is simply applied to the expanded graphite molded body or dried after impregnation to remove the solvent. Since the curable resin is further cured by heat treatment, the resulting low-density expanded graphite molded product has good heat resistance and high mechanical strength, so thermosetting resins are preferable. As a thermosetting resin,

形体を黒鉛化処理した低密度膨張黒鉛成形体を用いる。When the operating temperature of the low-density expanded graphite molded body is around 500°C, the expanded graphite molded body is coated with or impregnated with a solution of furan resin, phenol resin, etc. that has a high carbonization yield, and heated to harden the resin. The resin is carbonized by firing. When used at a higher temperature, a low-density expanded graphite molded body obtained by graphitizing the carbide-containing molded body is used.

iE#'' i is preferably 5 to 15% by weight. If the amount of impregnation is too small, there will be no effect of improving mechanical strength, and if it is too large, the molded product will be greatly deformed when the resin is hardened, carbonized, or graphitized. In addition, problems such as cracks in the molded body are likely to occur.
