Abstract

PURPOSE:To satisfactorily and ultrasonically weld different plastic materials with each other, by interposing the laminate of two resin films compatible to each of said different materials in a gap between the surfaces of the different plastic materials to be connected, and applying ultrasonic waves thereto. CONSTITUTION:In welding a core member 1 composed of polypropylene to a resin clip 2 composed of ABS resin, a double-layered laminate film 3 is interposed between the core member 1 and the resin clip 2. Said film 3 comprises a polypropylene-denatured film 3a at the surface facing to the core member 1 and a nylon film 3b at the surface facing to the clip 2, and these films 3a, 3b are prelaminated with each other through a hot laminate or adhesive agent. The film 3 and the resin clip 2 are provided at the predetermined positions of the core member 1, and ultrasonic waves are applied thereto while pressing the top end of an ultrasonic horn 4 onto the flange part 2a of the resin clip 2. Thus, the resin clip 2 is welded to the core material 1.

This method utilizes the fact that heat is generated and the parts are melted and welded together, and is applied to joining plastics.

同士の溶着は全く行なわれていない。However, although this welding method is applied to ultrasonic welding of homogeneous materials, such as polypropylenes or ABS resins, it has never been used to weld dissimilar plastics together.

っていた。For example, it is said from experience that adhesion between ABS and polypropylene, or between polar resin and non-polar resin is difficult to fuse.For example, crystalline resin generally has a high amplitude and energy due to its high fusion temperature and heat of fusion. Therefore, in this state, the non-toxic resin melts down to the base, and therefore, good adhesion cannot be achieved. For this reason, welding technology using this type of ultrasonic welding method cannot meet various assembly specifications. For example, when joining polypropylene and ABS, etc., instead of this method, adhesive Regional connections had become inevitable.
