[0003] The odor generated in a heat exchanger as an air conditioner component is also of great interest. That is, in the case of a hydrophilic film formed with the above-mentioned inorganic compound as a main component, there is a problem that inorganic odors such as dust odor and cement odor are strongly generated, giving a feeling of discomfort. In the case of a hydrophilic film formed mainly of the organic polymer compound, the odor of the film itself is small, but when used for a long time, microorganisms such as molds and bacteria are generated on the film, and putrefaction odor is generated. An unpleasant odor such as occurs. In particular, the generation of unpleasant odor is further promoted under an atmosphere of high temperature and high humidity. As means for suppressing this, there is a method in which a bactericide is added to the hydrophilic treatment agent in advance, or a bactericidal agent is directly sprayed on the heat exchanger with a deodorant spray or the like. The antiseptic odor control effect can be obtained by adding a small amount of antibacterial agent, but
It is not necessarily toxic to the human body handling it. As a substance that suppresses odor, there is a method in which activated carbon having an excellent odor substance adsorption ability is added to the hydrophilic film.
However, there are problems such as re-release of the adsorbed odor substance in a high-humidity atmosphere and deterioration of hydrophilic sustainability.

[0004] In a treatment method using a roll coating method, in the case of a pre-coat method in which a hydrophilic treatment agent is applied to the surface of an aluminum-containing metal material, heated and dried, and then formed, the processing is performed under severe processing conditions such as ironing and drilling.
An unpleasant odor may be generated due to friction generated between the mold and the film. In addition, the film mainly composed of an organic polymer compound is thermally decomposed or thermally oxidized by frictional heat,
Deterioration of the film occurs, generating an unpleasant odor. Even when no odor is generated during the molding process, a thermal decomposition product of the organic polymer film exists on the film surface or inside the film, which may be volatilized in the early stage of the operation of the air conditioner and an unpleasant odor may be felt. The above-mentioned problems concerning the generation of odors occur in the working environment when manufacturing the heat exchanger and in the indoor environment when the air conditioner is operating, and thus many users feel uncomfortable. Various proposals have conventionally been made for such odor control.

[0005] For example, JP-A-9-272818 discloses a "hydrophilic treatment composition for heat exchange". However, since the odor is felt from the film obtained by the disclosed technique, the odor prevention is not perfect.
Japanese Patent Application Laid-Open No. Hei 8-232320 discloses a hydrophilic aqueous treatment agent and a hydrophilic treatment method for an aluminum-containing metal material. This treating agent contains an antibacterial agent as an essential component for preventing the generation of an offensive odor, but the antibacterial agent is synthesized by a chemical reaction, and the toxicity of the antibacterial agent itself to the human body is not necessarily low. It can not be said. Further, as a technique relating to deodorizing properties, "Deodorizing filter" of JP-A-62-90168 and "Processing method of fiber having deodorizing function" of JP-A-2-251681 have been disclosed. Although the deodorizing effects of these inventions are recognized, their uses and fields are completely different from the technical fields and uses of the present invention, and are not suitable for the uses of the present invention. Japanese Patent Application Laid-Open No. 5-45083 discloses that “Al fin material for self-deodorizing heat exchanger” does not generate an unpleasant odor at the time of press working, but contains water-dispersed silica. Due to the dew water during the cooling operation, silica becomes apparent on the film surface, generating an unpleasant inorganic odor. Therefore, at present, a composition capable of forming a hydrophilic film capable of simultaneously imparting excellent hydrophilicity, deodorant property, and deodorant property to the surface of an aluminum-containing metal material has not been obtained.

Here, in the term relating to the above-mentioned odor, "deodorization" means that no unpleasant odor is generated from the surface and bulk of the hydrophilically treated aluminum material manufactured by applying the present invention, and that friction during processing is not caused. This means that there is no unpleasant odor generated due to the film decomposition product due to heat. However, that the above-mentioned deodorizing effect is obtained means that the odor is lower than a level that can be perceived by humans, and does not mean that the odor is not generated. In addition, "deodorization" means that in an atmosphere where malodorous substances such as acetaldehyde, ammonia, trimethylamine, and mercaptan are present, an organic hydrophilic film formed on an aluminum-containing metal material actively reacts with these substances. , Means reducing their abundance.
