  Next, using the interface reformer shown in FIG. 1 as described above, an example of polybutylene terephthalate (PBT) resin having a high melting point and crystallinity in an aluminum alloy molded body is used in the present invention using insert molding technology. The outline of the molding technique will be described with reference to FIGS.

  2, 3 and 4 are cross-sectional views for explaining the process of the present invention. FIG. 2 is a drawing of an aluminum alloy which has been press-molded and anodized (alumite treated) in advance. It is a schematic sectional drawing which shows the structure of a body example and visually, In the same figure, 21 is a box-shaped housing | casing.

  In the present invention, as a step prior to insert molding, first, a molded body of the aluminum alloy shown in FIG. 2 with the silane-based modifier compound using the interface reformer shown in FIG. When the entire inner surface 22 (modified surface) of the (box-shaped housing) 21 is treated with a flame containing the silane-based modifier compound, as shown in FIG. An interfacial modified layer (silicon dioxide film layer) 31 having a nanometer thickness could be formed. Incidentally, while the wetness index (JIS K6768) before the interface modification of the aluminum alloy molded body (box-shaped housing) 21 was 42 dyne / cm, the interface reformer shown in FIG. 1 was used. After the flame treatment, the wetting index (JIS K6768) was 73 dyne / cm or more, which means that the modified surface was remarkably activated compared to before the interface modification. Moreover, when the water contact angle was measured, it became 0 ° as much as possible, and a super hydrophilic phenomenon was exhibited.

  Next, the interface-modified aluminum alloy molded body (box-shaped housing) 21 illustrated in FIG. 3 is placed in an injection mold that is set in advance in an insert mold molding machine (not shown). Next, the modified interface 31 surface of the aluminum alloy molded body (box-shaped housing) 21 is set to be a molding surface, and then polybutylene terephthalate resin (PBT) compound is insert-molded. As a result, a dissimilar joint of an aluminum alloy and a polybutylene terephthalate resin (PBT) resin 41 was obtained. The adhesion / adhesion strength at the joint surface between the aluminum alloy and the polybutylene terephthalate resin (PBT) 41 is such that the polybutylene terephthalate resin (PBT) 41 breaks in the test result in the tensile strength tester. The adhesive interface strength was sufficiently satisfied, and the required adhesion / adhesion strength was sufficiently satisfied.

  It should be noted that in the present invention, it is particularly important to note that an adhesive / adhesion modifier is not particularly required when the resin used for insert molding is generally a resin having a polar group or a functional group. In the case of engineering plastics such as polybutylene terephthalate resin (PBT) having no functional groups or functional groups, a very small amount (0) of a coupling agent that serves as an adhesion / adhesion modifier such as a silane coupling agent at the time of resin compound production .About 1 to 1 W%) is an essential requirement. Incidentally, in the case of polybutylene terephthalate resin (PBT), for example, a silane coupling agent such as β-aminomethyl / aminopropyl / trimethoxysilane is effective.

  Generally, when different types of metal such as aluminum alloy and engineering plastics such as polybutylene terephthalate resin (PBT) are simultaneously molded by an insert mold molding machine, before molding the insert mold, The metal side is subjected to an epoxy resin primer treatment or anodized aluminum alloy molding as shown in Patent Documents 1, 2, and 3 mentioned above, and then the oxide layer coating at the bonded portion is destroyed. An etching process for contacting with an acidic aqueous solution and a special process for contacting with at least one selected from ammonia, hydrazine and a water-soluble amine compound are added in advance. Engineering plastics such as butylene terephthalate resin (PBT) The firm adhesion and bonding between the tick it is extremely difficult to secure. However, as described above, the interface modification apparatus shown in FIG. 1 according to the present invention is effectively used at the modification interface of various molded article adherends (base materials), thereby making it difficult to adhere and difficult. It is possible to activate all adherend surfaces (interfaces), which are said to be in close contact, and in the polymer primer treatment as an adhesion / adhesion aid that has been required in the past and aluminum alloy-based moldings. One or more selected from ammonia, hydrazine and a water-soluble amine compound, and an etching process in which the aluminum alloy-based molded product is anodized and then the oxide layer coating at the bonded portion is destroyed and brought into contact with an acidic aqueous solution. It is possible to reliably eliminate the so-called special process of contact with the substrate, and to reliably perform adhesion or adhesion at the adhesion interface. Omitting optionally polymer-based Purama or the special pre-treatment it is possible to provide a time and economic benefits of that possible.
