【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、接合しようとする二つの合成樹脂材料の一方
からレーザ光を照射して、その両者を接合する方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of joining two synthetic resin materials to be joined by irradiating a laser beam from one of the materials.
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.
すなわち、前者の物理的接合方法は、接合しようとする
合成樹脂材料の接合面でメタルメ・ノシュ等の発熱体を
発熱させて両者の合成樹脂材料の接合面を溶融させつつ
加圧・冷却し、再合成樹脂材料を接合する方法である。In other words, the former physical joining method involves heating a heating element such as a metal mesh on 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 resynthesized resin materials.
また、後者の化学的接合方法は、接合しようとする合成
樹脂材料の接合面にホットメルト等の接着剤を介在させ
、一方の合成樹脂材料の表面から高周波または超音波を
付与させて接着剤を加熱・熔融させた後、両者の合成樹
脂材料を加圧しつつ冷却し、再合成樹脂材料を接合する
方法である。In the latter chemical bonding method, an adhesive such as hot melt is interposed on the joint surfaces of the synthetic resin materials to be bonded, and high frequency or ultrasonic waves are applied from the surface of one synthetic resin material to bond the adhesive. After heating and melting, both synthetic resin materials are cooled while being pressurized, and the synthetic resin materials are rejoined.
しかし、前者の物理的接合方法においては、同種の合成
樹脂材料を接合する際には接合しようとする両者の合成
樹脂材料の溶融温度が同一であるとともに、相溶性を有
するので、両合成樹脂材料の接合には適しているが、異

の溶融温度が異なるとともに、相溶性が悪いことから、
両合成樹脂材料の接合は困難である。また、後者の化学
的接合方法においては、同種の合成樹脂材料を接合する
際には前者の物理的接合方法と同様に通しているが、異
種の合成樹脂材料を接合する際には合成樹脂材料の材質
によって接着剤の接着力が低下し、両合成樹脂材料を強
固に接合することは困難である。さらに、同種の合成樹
脂材料でもポリプロピレン樹脂のように相溶性の悪い合
成樹脂材料では異種の合成樹脂材料と同様に強固に接合
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 have the same melting temperature and are compatible, so both synthetic resin materials are 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 both synthetic resin materials. In addition, in the latter chemical joining method, when joining synthetic resin materials of the same type, the material is passed through in the same manner as the former physical joining method, but when joining different kinds of synthetic resin materials, the synthetic resin material The adhesive force of the adhesive decreases depending on the material of the material, making it difficult to firmly join both synthetic resin materials. Furthermore, even if the synthetic resin materials are of the same type, it is difficult to firmly bond synthetic resin materials with poor compatibility, such as polypropylene resin, in the same way as with different types of synthetic resin materials.
上述のようなことから、異種または同種でもポリプロピ
レンのように相溶性の悪い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 synthetic resin materials of poor compatibility, such as polypropylene, even if they are of the same or different types. A typical example will be explained using a method of joining polypropylene and polyethylene shown in FIG.
第２図６ごおいては、５１はポリプロピレン樹脂からな

通孔５３ａ、５３ｂには上方からパツキン５４を介在し
て螺子５５が螺合され、両板部材５１．５２が接合され
ている。In FIG. 2, 6, reference numeral 51 denotes a plate member made of polypropylene resin, and a plate member 52 made of polyethylene resin is disposed at the bottom of this plate member 51. and the plate member 51 made of polypropylene resin have through holes 53a, 53 in opposing parts.
b is formed. Then, screws 55 are screwed into the through holes 53a and 53b of both plate members 51 and 52 from above with a packing 54 interposed therebetween, thereby joining both plate members 51 and 52.
しかしながら、このような機械的接合方法においては、
両板部材５１．５２に貫通孔５３ａ、５３ｂを形成し、
端子５５を螺合しなければならず、前記の物理的接合方
法および化学的接合方法に比較して接合作業が煩雑とな

、５３ｂを形成する必要があることから、両板部材５１
，５２の強度が低下する不具合がある。However, in such mechanical joining methods,
Through holes 53a and 53b are formed in both plate members 51 and 52,
The terminals 55 must be screwed together, which makes the joining work more complicated than the physical joining method and the chemical joining method.
, 53b, both plate members 51
, 52 has the problem of decreasing strength.
