Abstract

PURPOSE:To make it possible to perfectly eliminate works for adhering and removing a molten material, by heating and melting the lower synthetic resin material among different synthetic resin materials by laser beam. CONSTITUTION:For example, an irradiation nozzle 5 of YAG: neodium<3+> laser 5a is brought into contact with the upper part of the piercing hole 3 formed to a resin plate member 2 and laser 5a is irradiated to rapidly heat and melt the surface of the plate member 1. Thereafter, when the valve 8 provided to a pipe 7 is opened to blow compressed air to the surface of the molten material 1a, not only a depression is formed but also the molten material 1a is built up from the piercing hole 3 in the amount corresponding to the volume of the depression and the thin wall part 4 of the piercing hole 3 is covered with the molten material 1a to strongly bond a plate member 1 and the plate member 2. As the synthetic resin for the member 2, there are polyethylene, polyvinyl chloride or polypropylene and, as the lower synthetic resin material 1 having absorbability to laser beam, there are a polypropylene resin, a styrene/acrylonitrile copolymer or the like. By this method, it is unnecessary to remove the molten material every when bonding is performed.

〔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接合方法と接着剤を用いて
接着する化学的接合方法が広く利用されている。Conventionally, when joining synthetic resin materials, a physical joining method in which heat is applied to weld them, and a chemical joining method in which they are joined together using an adhesive have been widely used.

合成樹脂材料の接合面にメタルメツシフ。In other words, the former physical bonding force method applies metal mesh to the joint surfaces of the synthetic resin materials to be joined.

脂４４２１を接合する方法である。This is a method of joining both synthetic resin materials by causing a heating element such as the above to generate heat to melt the joint surfaces of both synthetic resin materials while pressurizing and cooling them. In addition, the latter chemical bonding method involves interposing an adhesive such as bondmelt on the joint surfaces of the synthetic resin materials to be bonded, and applying high frequency or ultrasonic waves (:j) from the surface of one synthetic resin material to bond them. After heating and melting the agent, both synthetic resin materials are cooled while being pressurized, and both synthetic resins 4421 are joined.

Although it is used for joining resin abrasive materials, when joining different types of synthetic resin phase $4, the melting temperatures of both synthetic resins + J r4 are different and the compatibility is poor, so the two synthetic resin materials are Joining is difficult. 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 force of the adhesive decreases depending on the material of the material, making it difficult to firmly join both synthetic 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２図に示すポリプロピレン樹脂とカラス繊維で

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 a polypropylene resin and a styrene-acrylonitrile copolymer reinforced with glass fibers as shown in FIG.

A through hole 53 is formed, and its thin portion 54 is formed to have a thickness of Q, 5 +u to 3 times.
