The present invention relates to aluminum-based composite materials, and includes Ti or Zr on the surface of aluminum or aluminum alloy.
Form a film mainly composed of aluminum or aluminum alloy, a film mainly composed of Ti or Zr, and coat the surface of the film with an organic-inorganic composite resin. By forming a sandwich structure consisting of a composite layer with an inorganic compound component and an organic-inorganic composite resin film, it is ideal for containers, switch covers, or heat exchange media, especially fin materials for pre-coated heat exchangers. The purpose of the present invention is to provide an aluminum-based composite material that has excellent corrosion resistance and workability. For example, in order to construct a fin material for a heat exchanger using a plate material of aluminum or an aluminum alloy (hereinafter simply referred to as aluminum), the aluminum plate material is subjected to processing such as deep marking, ironing, overhanging, etc.
It is configured in a predetermined shape. When aluminum is used as a fin material for a heat exchanger, the surface of the aluminum may be coated with an organic resin, for example, in order to improve its corrosion resistance. Although the heat exchanger fin material made by subjecting such organic resin-coated aluminum to specified processing can provide the desired corrosion resistance, the surface of the heat exchanger fin material is also required to be hydrophilic. Therefore, instead of simply coating aluminum with an organic resin, it is preferable to coat aluminum with an organic-inorganic composite resin. However, the addition of inorganic compounds to the organic-inorganic composite resin formed on the aluminum surface deteriorates the airtightness and moisture permeability of the surface, and for example, it absorbs atmospheric moisture during storage before processing. This results in poor adhesion of machining oil during machining, resulting in poor lubricity and poor machinability.Also, adsorbed moisture penetrates the interface between the composite resin and the base aluminum, and this moisture causes corrosion. It also acts as a chemical substance, resulting in a decrease in corrosion resistance, and the composite resin may peel off due to trichlene and weak alkaline degreasing after processing. The present invention eliminates the above-mentioned drawbacks, and the aluminum-based composite material according to the present invention will be explained below. For example, after degreasing and washing an aluminum material of a predetermined shape used as a fin material for a heat exchanger with water, approximately 0.05 to 100 mg/kg of aluminum is applied to the surface of the aluminum material in a film.
m 2 , preferably about 0.5 to 5 mg/m 2 of Ti amount or
After forming a film with a Zr content, if there is moisture on this film, the water on the film surface is heated to a temperature that does not deteriorate the mechanical properties of aluminum, usually at 300°C.
℃ or less, preferably about 60 to 200℃, and then apply a water-soluble organic-inorganic composite resin uniformly on the surface of the film mainly composed of Ti or Zr using, for example, a reverse roll method. It is applied to As a material for forming a film containing Ti or Zr as a main component, titanium fluoride salt solution such as K 2 TiF 6 , zirconium fluoride salt solution, or product name BT3751 (alkaline phosphoric acid) manufactured by Nippon Parkerizing Co., Ltd. A chemical conversion agent containing salt and/or phosphoric acid as a basic component and a titanium salt of tannin or a titanium salt of tannic acid is dissolved in deionized water to adjust the pH to 2.5 to 4.5). ,
In addition, as organic-inorganic composite resins, the organic resin component of organic-inorganic composite resins includes urethane resins and inorganic resins, such as silica-acrylic composite-melamine resin type paints and silica-urethane composite paints. Saturated carboxylic acids or their derivatives (acrylic acid, methacrylic acid esters, amides, imides, especially acrylic melamine resins), olefins (polyethylene, polypropylene), or copolymers thereof are used, and organic-inorganic composites are used. The inorganic compound component of the resin is a water-absorbing substance, such as SiO 4-4 .
A silicate having the basic structure is used. The product obtained in this way has a layer between the base film containing Ti or Zr as a main component (usually coexisting with F) and the organic-inorganic composite film on the aluminum surface. It is composed of a composite layer with the water-absorbing inorganic compound component in the body film, and due to the existence of this composite layer, even when aluminum-based composite material is molded, the organic-inorganic composite on the surface No cracks occur in the film,
It has good processability, excellent corrosion resistance, and also good water wettability. In particular, if the composite layer consisting of the base film of Ti or Zr and, for example, a material mainly composed of SiO 4-4 , has a thickness of approximately several + Å, the workability and corrosion resistance are excellent, and it is necessary to construct such a composite layer. It is necessary that the thickness of the layer constituting the film mainly composed of Ti or Zr is about 10 to 200 Å, and the thickness of the organic-inorganic composite resin coating layer is about 0.5 to 3 μm. In addition, when the film of the aluminum-based composite material of the present invention thus obtained was examined by X-ray photoelectron analysis (ESCA), for example, as shown in the drawing, Al, Al 2 O 3 , SiO 4-4 were found . It can be seen that a composite layer, which is thought to be a compound of , Ti, and F, coexists.
In the figure, the lower graph shows the surface of the organic-inorganic composite film, and the upper graph shows the composite layer. Hereinafter, specific examples of the present invention will be described. Example 1 JIS1200-H24 aluminum alloy foil (coil width
500mm, coil length 3000m, coil thickness 0.110mm)
Ti
After forming a chemical conversion film (total Ti amount: 3 mg/m 2 ) mainly consisting of , it is dried at 80°C for 30 seconds to remove moisture on or in the chemical conversion film. Next, a water-dispersible silica-acrylic composite-melamine resin type paint manufactured by Kansai Paint Co., Ltd. (ASM4155 modified, acrylic-silica-melamine resin, solid content 17.5% (SiO 2 content 40%) was applied on the above chemical conversion film. ),

Heat and dry for 2 seconds. Fins of a predetermined shape are formed by subjecting the composite material pre-coated on the surface of the aluminum foil to drawless press processing including ironing, and after processing, the fins are assembled. It is degreased to remove oil that has adhered to it during the processing process, and a heat exchanger with a small fin pitch is constructed. Example 2 For JIS1200-H22 aluminum alloy foil,
A chemical conversion film is formed in the same manner as in Example 1, and then an organic-inorganic composite resin is applied. Fins of a predetermined shape are formed by drawing-pressing the composite material, which has been pre-coated on the surface of the aluminum foil with a pattern, for example, and assembling the fins after processing. Triclene degreasing treatment is applied to remove oil adhering during the processing process, and a heat exchanger with a small fin pitch is constructed. Example 3 The same wrought material as in Example 1 was degreased by slight etching, and then immersed in a 1% potassium zirconium fluoride (K 2 ZrF 6 ) bath at a temperature of 60 to 65°C for about 16 to 17 seconds to improve the surface of the wrought material. After forming a chemical conversion film containing Zr as a main component, it is dried at 120°C for 30 seconds to remove moisture on or in the chemical conversion film. Next, a water-dispersible silica-urethane composite paint made by Nippon Parkerizing Co., Ltd. is applied onto the above chemical conversion film using a reverse roll method so that the thickness after drying is approximately 1.1 to 1.6 μm. Heat dry at ~240℃ metal temperature for about 20 seconds. The composite material whose aluminum foil surface was precoated in this manner was processed in the same manner as in Example 1 to construct a heat exchanger. Comparative Example 1 A heat exchanger was constructed in the same manner as in Example 1 except that the step of forming a chemical conversion film containing Ti as a main component in Example 1 was omitted. Comparative Example 2 After slightly etching and degreasing the wrought material of Example 1,
After drying at 120℃ for 30 seconds, organic
Different from inorganic composite resin, for example, NP Alcoat LX80-119 (acrylic-melamine resin type paint,
(manufactured by Nippon Paint Co., Ltd.) applied 2μ thick and heated to 200 to 220℃.
The heat exchanger was then heated and dried for 30 seconds at a metal temperature of 100 mL, and processed in the same manner as in Example 1 to construct a heat exchanger. The press moldability, corrosion resistance, trichlene washability after processing, etc. of the product obtained as described above were measured and the results are shown in the table.
