METHOD FOR MANUFACTURING AUTOMOBILE DOOR

Japanese Patent JP2023097194

A

To provide a method for manufacturing an automobile door which has short joint process time and long open time, has a transparent member and a support, and has high joint strength between both of the members, and an automobile door which has a transparent member and a support, and has high joint strength between both of the members.SOLUTION: A method for manufacturing an automobile door includes a pre-joint step of preparing a laminate where a transparent member (2), a solid adhesive containing an amorphous thermoplastic resin that is at least any one of a thermoplastic epoxy resin and a phenoxy resin as a main component, and a support (5) which is joined to the transparent member are disposed in this order, and a joint step of heating and pressurizing the laminate and melting the solid adhesive, and joining the transparent member and the support. An epoxy equivalent of the amorphous thermoplastic resin is 1,600 or more, or the amorphous thermoplastic resin does not contain an epoxy group, and a fusion heat of the amorphous thermoplastic resin is 15 J/g or less.SELECTED DRAWING: Figure 3
