Problems solved by technology

The "aluminum radiating sheet for self-deodorizing heat exchangers" in JP-A-5-45083 was not approved due to the peculiar smell produced during pressurized processing, and because it contains water-dispersed silica, under long-term use, due to cold air The dew produced during operation makes silica appear on the surface of the film, resulting in bad inorganic odor

Embodiment 1～9 and comparative example 1

[0050] On the pre-cleaned aluminum plates (JIS1050 material, thickness 0.1mm x width 20mm x length 30mm) in Examples 1 to 9 and Comparative Example, 20mg / m of chromium was applied respectively. 2 Phosphate chromate treatment, adjust the solid content concentration of the hydrophilic treatment agent of the present invention as shown in Table 1 to 10%, roll-coat this coating solution on both sides of the aforementioned chromate-treated aluminum plate, and apply After cloth, heat and dry at the plate temperature of 220°C, and the amount of dry film formed is 1g / m 2 hydrophilic membrane.

[0051] The performance of the obtained hydrophilic film was evaluated according to the following experiments and evaluation criteria. (1) Hydrophilicity

[0052] Drop 5 μl (microliter) of deionized water on the surface of the material film after hydrophilic treatment, and the contact angle of the formed water droplet is measured with a contact angle meter (manufactured by FACE BA-P Kyowa Inte...

Abstract

The invention provides an organic hydrophilic treatment agent for an Al-containing metal having high hydrophilicity, and odor preventive and a deodorization effects, suitable for fins for heat exchange, and to provide a method for the hydrophilic treatment using the agent. The surface of an Al-containing metal material is coated with the treatment agent comprising a water-soluble polymer compound (A) to which one or more kinds of carboxy group, amide group, hydroxy group, sulfo group and phosphonic group are bonded, a phenol compound (B) in which five or more total OH groups are directly bonded to a polycyclic structure having an aromatic nucleus structure and, if required, a glycidyl group-containing organic compound (C), and the treatment agent is heated and solidified to form a hydrophilic coating film.

Description

technical field [0001] The present invention relates to an organic hydrophilic treatment agent and its treatment method for hydrophilizing the surface of aluminum-containing metal materials containing aluminum or aluminum alloy materials; in more detail, the present invention relates to a An organic hydrophilic treatment agent that forms a film capable of exerting superior hydrophilicity, deodorization, and deodorization effects on an aluminum-containing metal material, and an aluminum-containing metal material treatment method using the treatment agent; in particular, the organic hydrophilic treatment agent of the present invention The water-based treatment agent and its treatment method are used in the fields of home appliances and automobiles, used as air-conditioning components, and suitable for the manufacture of heat exchanger fins. Background technique [0002] It is generally known that a composition for forming a hydrophilic film on the surface of an aluminum fin fo...
