Abstract

PURPOSE:To make it possible to easily bond both synthetic resin materials without lowering the strength thereof, by interposing metal mesh having high m.p. between bonding surfaces before irradiating laser beam from one side. CONSTITUTION:Metal mesh 3 is placed on the surface of a synthetic resin material 1 and laser beam is irradiated from above to melt said materials 1 and the molten resin 1c is built up while entangled with the metal mesh 3. Further, a synthetic resin material 2 is superposed on the surface of said molten material 1 and the vicinity of the molten region is irradiated with laser beam from the surface of the synthetic resin material 2 to melt said material 2 while the molten resin 2b thereof is entangled with the molten resin 1c and the metal mesh 3. Because the molten resins 1c, 2b are mutually entangled and also fused together with the metal mesh 3 in an entangled state, the synthetic resin materials 1, 2 are strongly fused and bonded without lowering in strength.

。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of superimposing different types of synthetic resin materials and bonding them together using a laser beam.

〔従来技術〕[Prior art]

従来、合成樹脂材料と合成樹脂材料とを接合する際には
、熱を加えて溶着する物理的−合方法と接着剤を用いて
接着する化学的接合方法が広りナリ用されている。Conventionally, when bonding synthetic resin materials, a physical bonding method in which heat is applied to weld them, and a chemical bonding method in which bonding is performed using an adhesive have been widely used.

法である。In other words, the former physical joining method uses a heating element such as a metal mesh to generate heat at the joining surfaces of the synthetic resin materials to be joined, melting the joining surfaces of both synthetic resin materials, and pressurizing and cooling them. This is a method of joining resin materials. In addition, the latter chemical bonding method involves interposing an adhesive such as Honmelt on the bonding surfaces of the synthetic resin materials to be bonded.
In this method, high frequency or ultrasonic waves are applied to the surface of one synthetic resin material to heat and melt the adhesive, and then both synthetic resin materials are cooled while being pressurized to join both synthetic resin materials.

固に接合することは困難である。However, in the former physical joining method, when joining synthetic resin materials of the same type, both synthetic resin materials to be joined have the same melting temperature and are compatible, so re-synthetic resin materials However, when joining different types of synthetic resin materials, the melting temperatures of the two synthetic resin materials are different and the compatibility is poor.
It is difficult to join resynthetic resin materials. In addition, the latter chemical bonding method is as suitable as the former physical bonding method when bonding synthetic resin materials of the same type, but it is suitable for bonding synthetic resin materials of different types. The adhesive strength of the adhesive decreases depending on the material, making it difficult to firmly bond resynthetic resin materials.

上述のようなことから、異種の合成樹脂材料を接合する
際には、機械的接合方法が多く利用されている。その代
表例を第３図に示すポリプロピレンとポリエチレンの接
合方法によって説明する。For the reasons described above, mechanical joining methods are often used when joining different types of synthetic resin materials. A typical example thereof will be explained using a method of joining polypropylene and polyethylene shown in FIG.

The screws 55 must be screwed together, which makes the joining work more complicated than the above-mentioned physical joining method and chemical joining method.

．． There is a problem that the strength of 52 is reduced.

It is an object of the present invention to provide a method for joining different types of synthetic resin materials that can be easily joined without reducing the strength of the synthetic resin materials.

る。In order to achieve the above object, the structure of the method for joining different types of synthetic resin materials according to the present invention is such that when overlapping different types of synthetic resin materials and joining them, the different types of synthetic resin materials are exposed to laser light. A metal mesh with a higher melting point than both synthetic resin materials is placed on the surface of one synthetic resin material, and a laser beam is irradiated from above to melt it, and compressed gas is injected into the melted area. After spraying the molten material so that it swells upward while entangling it with the metal mesh, the other synthetic resin material is placed on top of the metal mesh, and a laser beam is directed from above toward the vicinity of the melted part of the one synthetic resin material. The metal mesh is irradiated to melt the metal mesh, and compressed gas is blown onto the melted area to cause the melt to become entangled with the metal mesh.

These synthetic resin materials can be freely selected and bonded in combinations arranged in the upper and lower parts.

り、変質したりして接合が不可能である。In addition, the wavelength of the laser used when joining different types of synthetic resin materials needs to be compatible with the synthetic resin materials to be joined, and a wavelength of 1.06 μm or less is best; In some cases, it is impossible to melt and join the joining surfaces of different types of synthetic resin materials to each other. In addition, the laser output is 5W to 30W.
W is suitable; if the output is less than 5W, the joint surfaces of different types of synthetic resin materials cannot be melted together, and if the output is more than 30W, the different types of synthetic resin materials may evaporate or change in quality. Therefore, joining is impossible.
