接着方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of bonding metal foil and polyamide film or sheet. More specifically, in bonding the metal foil and the polyamide film or sheet, an amino group-containing alkyltrialkoxysilane is coated on the metal foil and dried, and then the polyamide film or sheet is thermally bonded. This invention relates to a method for adhering sheets.

に吸水防止のマスキング加工を施す必要がある。 Conventionally, there have been many proposals for laminating metal foil and polyamide film or sheet by thermal adhesion (press bonding) or extrusion lamination for use in electric heating blankets, electronic carpet packaging materials, and the like. However, the laminate produced by this method does not have sufficient adhesive strength, and when stress such as bending, compression, tension, etc. or repeated stress is applied from the outside, the adhesive strength is extremely reduced, making it difficult to use for a long period of time. In addition, since the polyamide film or sheet in the laminate produced by this method has strong water absorption, in an atmosphere that promotes moisture absorption, the adhesive strength may be reduced due to the external stress, and spontaneous peeling may occur. For this reason, in some cases, it may be necessary to perform a masking process to prevent water absorption at the same time as thermal bonding.

定化させることが好ましい。 That is, when bonding a metal foil and a polyamide film or sheet, an amino group-containing alkyltrialkoxysilane is applied to the metal foil and dried, and then the polyamide film or sheet is thermally bonded, thereby economically and efficiently bonding the metal foil and the polyamide film. Alternatively, a method has been achieved that can permanently and permanently improve the adhesive strength of the sheet. Furthermore, prior to adhering the metal foil and the polyamide film or sheet, the metal foil, which has been coated with an amino group-containing alkoxysilane and dried, is heat-treated at 100°C to 280°C, and the amino group-containing alkyltrialkoxysilane is applied to the metal foil. Preferably, the adhesion is increased and stabilized by pre-crosslinking on top.
