The surface of metal material such as aluminum plate has holes, cracks, and irregularities. For materials with such a non-smooth surface,
In order to obtain a sufficient adhesive strength, it is necessary that the adhesive penetrates into the holes, cracks and recesses on the surface of the metal material and wets the surface sufficiently. In order to stabilize the coating amount when applying the adhesive and to improve the wettability on the metal surface, the adhesive is heated to an appropriate temperature to reduce the viscosity. However, the metal material itself to which the adhesive is applied has not been heated.

Therefore, since the adhesion between the metal surface and the adhesive is poor, water, salt water, etc. easily enter the adhesive interface, resulting in a decrease in the adhesive strength. The present invention has been made in view of the above conventional problems, and it is an object of the present invention to provide a bonding method that does not cause poor interface adhesion and exhibits excellent adhesiveness even under environmental conditions such as water, humidity, and salt water.

First, prior to the evaluation, a salt spray tester according to JIS K-5400 was used to perform a salt spray process on each test piece after adhesion. Next, the shear adhesive strength as the resistance to salt water is measured by the following method. The shear bond strength is 300 hours, 500 hours,
The test pieces after 1000 hours of treatment were measured in accordance with JIS K-6850 for the examples and comparative examples. The measurement results are shown in Table 1 and FIG.

-Pa / cm 2 . Thus, the embodiment has 100
Even after being left for 0 hour, there is little decrease in shear adhesive strength. On the other hand, in the comparative example, the shear bond strength is significantly reduced.

内に,有機接着剤3が流れ込み易くなる。The reason is considered as follows. That is, in the bonding method of the embodiment, the metal material 1 and the organic adhesive 3 are heated to about 60 ° C. before bonding. Therefore, on the surface of the metal material 1, the organic adhesive 3
Has a lower viscosity and becomes easier to diffuse. As a result, no poor interface adhesion occurs between the metal material 1 and the mating material 2. Also, fine pores (recesses) on the surface of the metal material 1
The organic adhesive 3 easily flows into the inside.

効果は生じないものと考えられる。Therefore, it is considered that the organic adhesive 3 permeates into the pores and solidifies to generate an anchor effect, and the mechanical adhesive strength is improved. On the other hand, in Comparative Example, the metal material 1 and the organic adhesive 3 were not heated when the metal material 1 and the mating material 2 were bonded, and therefore it is considered that the effect as in the above embodiment does not occur.

In the example, the occurrence of rust was visually observed for the first time 1000 hours after the adhesion, whereas in the comparative example, the occurrence of rust was visually observed after 500 hours and a large amount of rust was generated after 1000 hours. The rust was confirmed by measuring the shear adhesive strength of the test pieces of Examples and Comparative Examples and then visually observing the fracture mode and the fracture surface.

る。また,錆の発生が防止できることも明らかである。Here, the measurement result of the shear adhesive strength indicates the adhesive strength against salt water since it is the adhesive strength after the salt water is sprayed on the test piece after adhesion by the method of JISK-5400. . Further, this saltwater-resistant adhesive strength indicates the degree of destruction of the adhered surface under the most severe conditions among various conditions by causing rust on the surface of the adherend metal material. Therefore, in this example, it is clear that the adhesive strength under various conditions such as salt water resistant adhesive strength, water resistant adhesive strength, and moisture resistant adhesive strength is improved over the comparative example. It is also clear that the generation of rust can be prevented.

It shows the percentage of each shear adhesive strength after the lapse of 0 hours. Further, the cohesive failure rate refers to the rate (percentage) of the portion where the adhesive itself is destroyed, calculated by visually observing the fractured surface and determining the fracture mode.

考えられる。Here, the breaking mode refers to a result obtained by visually observing a peeled state (breaking state) of an adhesive portion, which occurs when the shear adhesive strength is measured.
As is known from Table 1 and FIG. 2, the retention rate of the shear adhesive strength is 61% even after 1000 hours has passed in the example, whereas the comparative example is remarkably low at 8%. It is considered that when the above retention rate is reduced to about 60 to 70, rust is generated at the adhesive interface, which causes reduction in the shear adhesive strength.

る。On the other hand, the cohesive failure rate is 30% in the example after 1000 hours. On the other hand, the comparative example is 5%, which is clearly inferior to the comparative example. This is also clear from the fact that the cohesive failure rate indicates the failure of the adhesive itself as described above. As described above, according to the bonding method of this example, the heat-curing type interfacial adhesion failure does not occur, and the bonding strength under various conditions such as salt water resistant bonding strength, especially the shear bonding strength is improved. Further, it is possible to prevent rust from occurring at the adhesive interface.
