PURPOSE:To combine perfluoroplastic with stabilized solid surfaces of metal or ceramics, etc., by bonding without special surface treatment or resinous material treatment. CONSTITUTION:This bonding method is provided with surfaces of metal, ceramics etc., as adherends on the one hand, and polytetrafluoroethylene, a kind of perfluoroplastic as an adherend on the other hand, and with adhesives such as phenol-formaldehyde, fluorinated ethylene propylene; etc., that are thermoplastic perfluoroplastics, and with spacers that are used to keep the thickness of an adhesive layer more than a specified value during bonding, and with bonding to polytetrafluoroethylene during which the adhesion temperature is higher than 340 deg.C, and the adhesion time is larger than the time for start of adhesion, corresponding to the adhesion temperature, etc., and with the condition under which the adhesives are fused and bonded to the adherends. In order to obtain a bonded product which has a surface of thermoplastic perfluoroplastic layer, bonding is done at the adhesion temperatures of approximately 320 deg.C, and polytetrafluoroethylene is used as a mold release agent. |
