（イ）産業上の利用分野
本発明は、熱交換器用フィン材に関し、特にその表面に
凝縮水が溜らないようにした熱交換器用フィン材に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a fin material for a heat exchanger, and more particularly to a fin material for a heat exchanger that prevents condensed water from accumulating on its surface.
（ロ）従来の技術

たり、或いは騒音が発生したりすることがあった。更に
、この凝縮水が通風方向へ飛散し冷房装置の各所や家屋
の各所を汚すこともあった。(b) Conventional technology Some heat exchangers are equipped with aluminum fins that have excellent heat conductivity in order to improve heat exchange efficiency. When performing air conditioning using this heat exchanger, warm air is cooled between the fins, but condensed water may adhere to the fins. This adhering and stagnant condensed water may narrow the air passage between the fins, reducing the amount of ventilation or causing noise. Furthermore, this condensed water sometimes scatters in the direction of ventilation, staining various parts of the air conditioner and the house.
このため、フィンの表面を親水化して凝縮水を薄い水膜
として流下させる方法が従来より行われている。親水化
の方法としては、例えばフィンの表面にアクリル酸系樹
脂を塗布する方法又はアクリル酸系樹脂と水ガラスとの
混合物を塗布する方法が知られている。For this reason, a method has conventionally been used in which the surface of the fin is made hydrophilic so that the condensed water flows down as a thin water film. As a method for making the fin hydrophilic, for example, a method of applying an acrylic acid resin or a method of applying a mixture of an acrylic acid resin and water glass to the surface of the fin is known.

と思われる。(c) Problems to be Solved by the Invention However, the former method still has the drawback that hydrophilization is not sufficient. Furthermore, although the latter method is somewhat satisfactory in terms of hydrophilization, it has the drawback that cracks occur when the fins are perforated or bent, and the film tends to peel off. This seems to be because an inorganic compound is mixed with the acrylic acid resin.
そこで本発明者等はこの点を解決すべく’ｊｌ１Ｍ検討

である。Therefore, the inventors of the present invention investigated 'jl1M to solve this problem, and found that by forming a film on the surface of the fin body using a film-forming substance such as acrylic acid resin and an organic substance in combination, cracks could occur. They discovered that it is possible to obtain a fin material with a sufficiently hydrophilic surface without any hydrophilic hydrophilic properties, leading to the present invention.

ましい。Chelating agents for chelating aluminum metal used in the present invention include butane-1,2,3,4-tetracarboxylic acid, ethylenediaminetetraacetic acid, propylenediaminetetraacetic acid, pentamethylenediaminetetraacetic acid,
Examples include cyclopencune-1,2-diaminetetraacetic acid, cyclohexine-1,4-diaminetetraacetic acid, and 2-hydroxytrimethylenediaminetetraacetic acid. Among these, ethylenediaminetetraacetic acid is most preferred because it has an excellent chelating effect, is inexpensive, and is easily available.
このキレート剤はフィン材の素材であるアルミニウムを
キレート化する作用を有し、形成された皮膜とフィン材
表面との密着力を向上させるものである。This chelating agent has the effect of chelating aluminum, which is the material of the fin material, and improves the adhesion between the formed film and the surface of the fin material.

チルスルホキシド等が用いられる。To form a film on the surface of the fin material body, a solution in which a film-forming substance, phytic acid, and a chelating agent for chelating aluminum metal are dissolved or dispersed in an organic solvent is applied to the surface of the fin material body, and then dried. to evaporate the organic solvent. As the organic solvent, cellosolve, ethylene glycol, propylene glycol, diethylene glycol, dimethylformamide, formamide, dimethyl sulfoxide, etc. are used.

レート剤との混合割合は、皮膜形成物質１００重量部に
対してキレート剤１．５〜２５重量部程度が好ましい。The mixing ratio of the film-forming substance and phytic acid is preferably about 5 to 35 parts by weight of phytic acid per 100 parts by weight of the film-forming substance. If the amount of phytic acid is less than 5 parts by weight, the hydrophilicity of the formed film tends to be low;
If the amount exceeds 5 parts by weight, the strength of the coating itself tends to decrease, and the coating tends to be prone to cracking. Further, the mixing ratio of the film-forming substance and the chelating agent for chelating aluminum metal is preferably about 1.5 to 25 parts by weight of the chelating agent to 100 parts by weight of the film-forming substance.

上しない傾向となる。If the amount of chelating agent is less than i, si, the adhesion to the aluminum metal that is the main body of the fin material tends to decrease, and even if the chelating agent is blended in an amount exceeding 25 parts by weight, it will not bond with the aluminum metal that is the main body of the fin material. The adhesion strength tends not to improve much.

Generally, the total amount of the film-forming substance, phytic acid, and chelating agent is 1 to 5 parts by weight per part.
