- JP 2008-80394 A Japanese Patent Laid-Open No. 5-50173 JP 2001-11665 A JP-A-4-160169
- the present invention that has solved the above problems is a method for producing a joined structure in which a steel plate and an aluminum plate are joined in a state of electrical continuity, wherein at least a joined surface on the steel plate side has a polyolefin-based resin and a polyurethane-based resin. And a method for producing a bonded structure of a steel plate and an aluminum plate, comprising a step of forming at least one resin film selected from the group consisting of epoxy resins with a film thickness of 0.1 to 5.0 ⁇ m.
- Any of the embodiments containing 0.1 to 20% by mass is a preferred embodiment of the present invention.
- a bonded structure of a steel plate and an aluminum plate with further improved contact corrosion resistance can be obtained.
- the steel plate is preferably a galvanized steel plate.
- the resin film it is preferable to form the resin film by a wringer roll drawing method or a roll coater coating method. After the resin film is formed, it is efficient to join the steel plate and the aluminum plate by resistance spot welding. It is.
- the present invention relates to a method for manufacturing a joined structure in which a steel plate and an aluminum plate are joined in a state of electrical continuity, and at least a facing surface of the aluminum plate on the steel plate side includes a polyolefin resin, a polyurethane resin, and an epoxy resin. It is characterized in that it includes a step of forming one or more resin films selected from the group consisting of resins with a film thickness of 0.1 to 5.0 ⁇ m.
- the aluminum plate of the present invention includes an aluminum alloy plate.
- the inventors of the present invention have contact corrosion if a resin film is formed on at least an aluminum plate facing surface (hereinafter simply referred to as a bonding surface) on the steel plate side of the bonding surface between the steel plate and the aluminum plate.
- the inventors have found that it can be effectively suppressed, and have completed the present invention. That is, according to the research results of the present inventors, by forming a resin film on the joining surface on the steel plate side, it is possible to effectively suppress the base corrosion corrosion on the aluminum plate side, If a resin film is also formed on the joining surface on the aluminum plate side, the contact corrosion resistance of the aluminum plate can be further improved. However, it was found that contact corrosion of the aluminum plate cannot be suppressed when the resin film is formed only on the joining surface on the aluminum plate side. The reason is considered as follows.
- a resin film that is thin enough to be welded must be formed.
- the film thickness is small, pinholes are likely to occur in the film.
- the absolute value of the corrosion current flowing between the steel plate and the aluminum plate will decrease, but the corrosion current will concentrate on the pinholes in the resin film. Only the aluminum in the pinhole part is eroded. As a result, the erosion depth of the aluminum plate is the same as that without the resin film, and contact corrosion proceeds.
- the absolute value of the corrosion current decreases, and current concentration on the aluminum plate surface does not occur, so the erosion depth of the aluminum plate reliably decreases. Also, if a resin film is formed on the joint surface on the aluminum plate side in addition to the steel plate side, the absolute value of the corrosion current is further reduced and no current concentration occurs on the aluminum plate surface, so the erosion depth of the aluminum plate is This is further reduced compared to the case where a resin film is formed only on the steel plate side.
- a resin film is formed at least on the joining surface on the steel plate side. As described above, it is preferable to form a resin film on the joining surface on the aluminum plate side in addition to the joining surface on the steel plate side.
- the resin film needs to be formed on the joint surface from the viewpoint of enhancing the contact corrosion resistance in both the steel plate and the aluminum plate. It doesn't matter.
- the resin for forming the resin film can be selected from polyolefin resins, polyurethane resins, and epoxy resins from the viewpoint of contact corrosion resistance and compatibility with electrodeposition coating. It is also possible to mix two or more of these resins.
- the resin is preferably contained in an amount of 20% by mass to 100% by mass in the resin film. If the amount of resin is too small, pinholes are likely to occur in the coating, and there is a risk of dropping off when silica is blended.
- the present invention is suitable for manufacturing a structure in which a steel plate and an aluminum plate are in surface contact via a resin film.
- a structure in which a steel plate and an aluminum plate are in surface contact via a resin film.
- the type of silica is not particularly limited, and dry silica and colloidal silica can be selected. If the type of coating solution for forming the resin film is solvent-based, dry silica, and if it is water-based, colloidal silica Is preferably used.
- the present inventors have the effect of suppressing the contact corrosion of aluminum by acting on the contact corrosion portion between the steel plate and the aluminum plate in order to further improve the contact corrosion resistance of the steel plate / aluminum plate joint structure.
- the inhibitor which has was searched the following thing was discovered.
- the inhibitor is preferably present in the film in the range of 0.1 to 20% by mass.
- the contact corrosion resistance of the steel plate / aluminum plate joint structure can be further improved.
- the content is less than 0.1% by mass, the effect of improving the contact corrosion resistance may not appear.
- it exceeds 20 mass% the improvement effect of contact corrosion resistance tends to become saturated, and it is economically useless.
- Inhibitors may be used alone or in combination of two or more.
- a resin film forming coating solution is applied by a ringer roll drawing method or a roll coater using a groove roll.
- a method of continuously applying only to a steel plate or each of a steel plate and an aluminum plate by an application method or the like and then baking and drying is preferable.
- the resin film is formed uniformly, the risk of corrosion from defective parts due to non-uniform coating can be reduced, and a highly reliable contact corrosion-resistant steel plate / aluminum plate joint structure can be obtained. . What is necessary is just to determine suitably the time and temperature of baking drying according to resin to be used. Moreover, as described above, the resin film may be formed on both surfaces of a steel plate or an aluminum plate.
- the aluminum plate a pure aluminum plate, an Al—Mn alloy plate, an Al—Mg alloy plate, an Al—Zn—Mg alloy plate, an Al—Si alloy plate, or the like is used.
- the resin film has a primary rust preventive action during storage before bonding and a friction coefficient reducing action during pressing, but if rust preventive oil is further applied, the primary rust preventive power during storage and Since the slidability improvement at the time of press work can be aimed at, it is preferable.
- ⁇ Chemical treatment, electrodeposition coating, and finish coating are usually applied to the bonded structure.
- the chemical conversion treatment include known base treatments such as phosphate treatment, chromate treatment, chromate-free pretreatment, silane coupling treatment, and the like.
- a steel plate (width 40 mm ⁇ length 110 mm ⁇ thickness 1.0 mm, the type of steel plate is shown in Table 1) was dipped in a coating forming coating solution, and then grooved. Excess coating liquid was squeezed with a roll, and then dried in a conveyor type drying furnace at a furnace temperature of 220 ° C. for 12 seconds to form a resin film on the steel sheet. The thickness of the resin film was adjusted by the drawing pressure of the groove roll and the concentration of the coating solution. Tables 2 and 3 show the composition of the coating solution and the thickness of the resin film. In Comparative Examples 1 to 7, no resin film was formed on the steel sheet (Table 3).
- the applied pressure was 3.5 kN
- the current was 26 KAm
- the energization time per spot was 120 ms.
- the caulking pressure was set to 150 bar (15 MPa).
