Title:

METHOD FOR WELDING MEMBER AND WELDING MEMBER

Document Type and Number:

Japanese Patent JP2009297910

Kind Code:

A

Abstract:

To provide a method for welding a welding member to a molding to be high in adhesive strength.

In the method for welding the welding member, to the molding 1 in which a welding surface 3 is formed from a first resin which is one of a polypropylene-based resin and a polyethylene-based resin, the welding member 10 in which at least a welding surface 14 is formed from a second resin which is the other of the polypropylene-based resin and the polyethylene-based resin is welded. A first adhesive resin layer 21 made of a resin of the same type as the first resin is arranged on the side of the molding 1, a second adhesive resin layer 22 made of a resin of the same type as the second resin is arranged on the side of the welding member 10, and the welding surface 3 of the molding 1 and the welding surface 14 of the welding member 10 are welded together. One of the resins of the first adhesive resin layer 21 and the second adhesive resin layer 22 is a maleic anhydride-modified resin, and the other is an epoxy group-having resin.
