いる。BACKGROUND OF THE INVENTION Conventionally, aluminum has been used as a fin material for heat exchangers because of its excellent thermal conductivity. These aluminum fins are generally subjected to some kind of surface treatment for the purpose of corrosion prevention, and then are pressed and put into practical use.

揮発性の高い揮発性プレス油が使用される傾向にある。[0003] Conventionally, press oil with a relatively high viscosity of 4 to 8 cst was used during press processing in this process, but in recent years, solvents (fluorocarbons, trichloroethane, trichlene, etc.) to remove press oil after press processing have been used. The viscosity is as low as 1 to 2 cst, with the aim of omitting degreasing by

問題が発生している。Volatile press oil has the property that most of the oil content evaporates after pressing due to its high volatility, making degreasing unnecessary. However, due to its low viscosity, conventional surface treatment is difficult. However, there is a problem in that the moldability is decreased, specifically, processing defects such as collar skipping, buckling, and peeling of the surface treatment film occur frequently, resulting in a decrease in productivity.

As a result of intensive research in order to improve the deterioration of workability caused by press oil through surface treatment, we have found that by surface treating a specific resin within a specified film thickness, good moldability is achieved regardless of lubricating oil. It has been found that the present invention can be obtained without impairing the excellent hydrophilicity characteristic of silica-based hydrophilic treatment.

が挙げられる。[Function] The aluminum fin material of the present invention is characterized by providing a silica-based hydrophilic treatment film containing SiO2 on the surface of the aluminum plate, and further providing a hydrophilic film with a thickness of 0.1 to 3.0 μm on the surface. The purpose of this invention is to provide a polymeric layer. Here, examples of the silica-based hydrophilic treatment film include those shown in the above-mentioned Japanese Patent Application Laid-Open No. 61-8598.

It needs to be in the range of 1 to 3.0 μm. This is 0.
If it is less than 1 μm, the surface coverage will not be sufficient and the wear reduction effect will be insufficient, while if it exceeds 3 μm, peeling of the film will easily occur during the ironing process of fin forming, and formability will decrease. It's for a reason.

えられる。[0013] By providing these hydrophilic polymer layers on the silica-based hydrophilic film, good moldability can be obtained even with volatile press oils having poor lubricity. The reason is that the soft resin layer This is thought to be because it prevents the mold from coming into direct contact with the hard silica film via the press oil, and acts as a buffer layer.

It is desirable to bake at the lowest temperature possible, below 200°C.

Second ironing punch 9.80mm, die 9.8

Regarding seizure, we observed the appearance of the second ironing punch after 50,000 punch presses and found ○ (no abnormality), △ (foreign matter adhesion).
Evaluation was made as follows: ``Seize-in'') and ``X'' (Foreign matter adhesion, punch flaws). Regarding film peeling, the remaining state of the surface treatment film on the inner surface of the collar of the fin processed product was investigated and evaluated as ○ (no peeling), Δ (partial peeling), and × (full peeling).

On the other hand, in the case of only silica-based treatment (Comparative Examples No. 6 to No. 7), although the use of conventional oil (No. 7) showed good results, the use of volatile press oil (No. 7) showed good results. In case of .6), some seizure occurs and mold wear tends to increase. Comparative example no. 8~No. No. 9 is an example in which the thickness of the hydrophilic resin film is outside the range of the present invention. No. 8 had insufficient mold wear reduction effect due to the thin film thickness; In No. 9, the film was too thick and the film peeled off on the inner surface of the collar. Comparative example N
o. No. 10 is an example in which a type of resin outside the scope of the present invention was provided, and the hydrophilicity tends to decrease.
