Embodiment

[0080] Hereinafter, the present invention will be described in more detail using examples of the present invention.

[0081] [Manufacturing method of test material]

[0082]An aluminum plate (plate thickness: 010 mm) made of pure aluminum-based A1200 (JIS H4000) was produced by a conventionally known production method. The aluminum plate was degreased with an alkaline agent ("Surfcleaner (registered trademark) 360" manufactured by Japan Pint Co., Ltd.) and treated with phosphoric acid chromate. The adhesion amount of the chemical film was 30 mg / m in terms of Cr. 2 .

[0083] Afterwards, the water-soluble resin composed of the copolymer of sulfonic acid group-containing monomers and acrylic acid monomers shown in Table 1 was diluted with pure water to a homogeneous component concentration of 5%, and the coating composition thus obtained was treated with phosphoric acid chromate. Coated 20mg / m on the aluminum plate after 2 The amount (the amount of water-soluble resin) is bak...

Abstract

In the invention, even when a heat exchanger or a component used for the heat exchanger (object component) is adhered with pollution matter such as VOC and the like, the pollution matter can be cleaned by dew generated on the surface of the object component. In the invention, water soluble resin used for coating composite used for coating the object component and capable of maintaining high hydrophilic of the object component for a long term is provided. It is characterized in that the water soluble resin is a polymer of 3-allyloxy-2-hydroxy-1-propanesulfonic acid (HAPS) or salt thereof and acrylic acid or salt thereof. The mole ratio of the composition module of the HAPS or the salt thereof and the composition module of all monomer in the polymer is around 23%. And the average molecular weight of the polymer is more than 50 thousand. The product (MH * MW) of the ratio and the average molecular weight is more than 300000 and less than 5000000.

Description

technical field [0001] The present invention relates to a water-soluble resin used in a coating composition for coating a heat exchanger or parts for a heat exchanger, a fin material for a heat exchanger using the same, and a heat exchanger. Background technique [0002] Heat exchangers are used in various fields including room air conditioners, packaged air conditioners, refrigerated display cases, refrigerators, oil coolers, and radiators. In heat exchangers such as room air conditioners and package air conditioners, aluminum or an aluminum alloy is used as the fin material from the viewpoint of excellent thermal conductivity and workability. [0003] During the air-conditioning operation of the heat exchanger, water vapor in the air condenses, thereby generating dew water on the surface of the fin material made of aluminum or an aluminum alloy. When the dew condensation water exists in the form of water droplets on the surface of the fin material, the ventilation resista...
