<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a damping rubber member capable of manufacturing the damping rubber member of high quality with excellent molding processability and mass productivity by suppressing the contamination of a mold, and the damping rubber member obtained thereby. <P>SOLUTION: The damping rubber member is manufactured by a process for forming an underside adhesive layer on the surface of a metal fitting 1 using a resorcinol type adhesive (A) and laminating and forming an upper side adhesive layer on the surface of the underside adhesive layer using a chlorosulfonated polyethylene (CSM) adhesive (B) containing no tackifier, a process for preparing a mold 3 having a molding recessed part and pressing the peripheral edge part 3A of the molding recessed part of the mold 3 to the surface of the adhesive layer 2 formed on the surface of the metal fitting 1, a process for penetrating a rubber composition in the cavity 4, which is formed by the surface of the adhesive layer 2 and the molding recessed part of the mold 3, under pressure in the pressing state of the mold 3, a process for vulcanizing the rubber composition and a process for demolding the rubber material formed by vulcanization from the mold 3 simultaneously with releasing the pressure of the mold 3. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
