Abstract

PURPOSE:To strongly join different kinds of two synthetic resin materials by a method in which two kinds of synthetic resin materials having a laser absorbability are melted by laser beam in such a way as to cause both melts to entangle with each other. CONSTITUTION:A recession 1b is formed on a glass fiber-reinforced styrene- acrylonitrile copolymer plate 1 containing carbon black, having a laser absorbability. A polypropylene resin plate 2 containing carbon black is then superposed on the plate 1. Laser beam 5 is irradiated onto the plate 2 from above to form a through hole 2b in the plate 2. Whereupon, the melt 2c is partly drooped down to the recession 1b of the plate 1. The laser beam 5 reaches the plate 1 through the plate 2 to melt the plate 2 likewise to form a recession 1c on the surface and also the melt 1d is partly heaped on the recession 1b. Compressed air is then blown from a pipe 7 in such a way as to strongly join the two melts 1d and 2c by entanglement.

。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.

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 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 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 different types of synthetic resin materials. A typical example will be explained using a method of joining polypropylene and polyethylene shown in FIG.

いる。In FIG. 2, 51 is 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 this plate member 52 of polyethylene resin and polypropylene resin are disposed. Through-holes 53a and 53b are formed in opposing parts of the plate member 51.
is formed. Then, screws 55 are screwed into the through holes 53a and s3b of both plate members 51 and 52 from above with a gasket 54 interposed therebetween, thereby joining both plate members 51 and 52.

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.

接合方法を提供することにある。(Object of the Invention) The present invention has been made to solve the above-mentioned problems, and its purpose is to irradiate the upper synthetic resin material with a laser beam among the superimposed synthetic resin materials so that both synthetic resin materials can be combined. By heating and melting the materials, then blowing compressed gas onto the melt and pushing it into the recess formed in one of the synthetic resin materials, it is possible to easily join the resynthetic resin materials without reducing their strength. The object of the present invention is to provide a method for joining different types of 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 recess is formed on one of the contact surfaces, and the two synthetic resin materials are overlapped, and a laser beam is irradiated from above the upper synthetic resin material to separate the two synthetic resin materials. While melting, compressed gas is blown onto the melted area, and the melt is forced into a recess formed in the contact surface of the one synthetic resin material and entwined with each other.
