Description of the Invention (I) Technical Field The present invention relates to a method for producing an aluminum heat sink material with improved corrosion resistance and adsorption properties, and a hydrophilic aluminum heat sink material produced by the method. O BACKGROUND OF THE INVENTION Aluminum and aluminum alloy materials have light weight, good processability and thermal conductivity, making them widely used in heat exchanger components, such as automobiles and room air conditioners. Especially for heat exchangers on some machines, aluminum heat sink materials have been used in many embodiments. When an air conditioner containing a fin material is operated in a cooling mode, the water vapor of the air in the atmosphere will condense on the surface of the fin material, causing blockage between the fins' and weakening the cooling capacity. To remove the condensed water, it is common practice to apply a hydrophilic treatment to the surface of the heat sink. Although a method of removing water has been implemented on the surface of the heat sink, in this method, a large amount of water is dropped by the water removing agent, causing blockage between the heat sinks, and the cooling capacity is greatly weakened. Therefore, this method is used today Has been rarely used. The hydrophilic treatment of the surface of the heat sink material is a basic treatment as described above. This hydrophilic treatment keeps the surface of the heat sink wet at all times of water condensation. Therefore, water penetrates the hydrophilic coating layer to form a high oxygen concentration gas chamber between the heat sink material and the solder, which results in the generation of a metal corrosion reaction, or the infiltrated water contains atmospheric pollutants, resulting in hydration, making A metal corrosion reaction occurs. Corrosion products generated by such reactions accumulate on the surface of the heat sink, reducing its heat exchange capacity. Another problem is that when operating in the heating mode, the corrosion products become white powder, and the 4 I paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) " (Please read the back first Please pay attention to this page and fill in this page again.) · ---— II I «1 II I--II. 510832 A7 ------- B7 V. Description of the invention (Y) With the hot air exhausted from the blower fan, enter the room . To overcome the above disadvantages, Japanese Kokai Publication Hei-5-125555 discloses a pre-coated heat sink material, which is manufactured by forming a hydrophilic coating layer, which includes an alkali silicate, a hydrophilic polymer, and a A specific proportion is attached to the dyed chromate coating layer of the aluminum substrate, and the hydrophilic coating layer is dried by heating. Summary of the Invention When dyeing chromate is used in the aforementioned Japanese Kokai Publication Hei-5_125555, basically from the environmental point of view, it is better to use a non-chromate chemical conversion treatment agent. When chromium-containing phosphate is used, it must be washed with an aqueous solution after chemical conversion treatment to prevent hexavalent chromium from remaining on the coating layer. But the treatment of chromium-containing wastewater generated when washed with an aqueous solution will cause other problems. However, there is no treatment method that can be used for a non-chromate treatment agent to form a heat sink material having sufficient corrosion resistance and moisture resistance. Therefore, the object of the present invention is to provide a method for producing an aluminum heat sink material using a non-chromate chemical conversion treatment agent that is better for the environment, and at the same time meet the required performance characteristics such as corrosion resistance and humidity resistance, and This method produces an aluminum heat sink material. The method for producing an aluminum heat sink material according to the present invention includes forming a chemical conversion coating layer in the chemical conversion treatment step of the aluminum substrate, and forming a corrosion-resistant coating layer and / or a floatable ( Water-borne) resin is a hydrophilic coating. The chemical conversion coating can be obtained by maintaining a chemical conversion treatment solvent within the following composition range and keeping the solvent temperature at 30 to 5. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). (Please read the notes on the back before filling this page)

DETAILED DESCRIPTION OF THE INVENTION Next, the present invention will be described in detail. In the background of the present invention, an aluminum heat sink material is a material for manufacturing a heat sink heat exchanger. The heat sink material is a ring-shaped plate-shaped aluminum plate or a rolled aluminum alloy that is rolled into a coil, and can be selectively degreased to obtain a chemical conversion treatment to form a corrosion-resistant coating and / or A hydrophilic coating composed of a water-borne resin.

The heat sink material having the chemical conversion coating layer, the corrosion-resistant coating layer and / or the hydrophilic coating layer formed in this way is cut, processed, and assembled into a heat exchanger. According to the method for producing a material for a heat sink of the present invention, the Ming or Ming alloy plate must first be degreased when necessary. Degreasing methods include degreasing with gasoline or cereals, and alkaline degreasing with alkaline solutions containing sodium hydroxide, sodium silicate, or sodium phosphate. These treatment methods can be appropriately selected and used according to the conditions of the aluminum material. In the chemical conversion treatment step shown below, the chemical conversion solution is sprayed on the heat sink material. The spray treatment time, that is, the time at which the solution at the chemical conversion contacts the heat sink material, is 1 to 10 seconds, and the treatment temperature (the temperature of the solution) is 30 to 70 C, preferably 40 to 60 ° C. If the above treatment time is less than 1 second, a sufficient chemical conversion coating layer cannot be formed. On the other hand, when the processing time is longer than 10 seconds, it is impossible to expect further improvement in power Sb characteristics and it is disadvantageous in terms of cost. If the processing temperature is lower than 30 ° C, the reactivity of the chemical conversion treatment agent is too low to form a sufficient chemical conversion coating layer. On the other hand, if the processing temperature exceeds 70 ° C, further improvement of the functional characteristics cannot be expected, and it is disadvantageous in terms of cost. In the embodiment of the present invention, the spraying treatment will be replaced by immersion or other techniques. The composition of the chemical conversion treatment solution used in the above chemical conversion treatment is: chromium ion 10 to 10,-ppm, preferably 100 to 1,000 ppm; phosphate ion 10 to 10,000 ppm, It is preferably 100 to! , 00ppm; aluminum ion 100 to 10,000PPm, preferably 500 to 5,000 ppm; effective fluorination 7 This paper size applies Chinese National Standard (CNS) A4 specification (210 x 297 mm) ( (Please read the notes on the back before filling out this page)

Description of the invention (^) 1 ~ 500 ppm of ion, preferably 1 to 10 ppm; organic acid with at least one phenolic hydroxyl group in the molecule 10 to 10,000 ppm, preferably 100 to 1,000 ppm pH 1.0 to 4.0, preferably 1.5 to 2.5. The zirconium ions mentioned above are obtained from fluorozirconic acid, lithium, sodium, potassium, ammonium and other fluorozirconic acid, zirconium sulfate, zirconium nitrate, zirconium hafnium nitrate, zirconium fluoride and the like. If the content of pin ions is less than 10 ppm, the zirconium content in the obtained chemical conversion coating is too low, which reduces the corrosion resistance and the adhesion of the hydrophilic coating. If it exceeds 10,000 ppm, it cannot be expected to further improve its functional characteristics, and it is disadvantageous in terms of cost. Phosphate ions can be added by adding phosphoric acid selected from the group consisting of phosphoric acid, ammonium phosphate, and alkali metal phosphates such as sodium phosphate, potassium phosphate, etc., alkaline earth metal phosphates such as calcium phosphate, magnesium phosphate, and the like and concentrated phosphoric acid. Compounds. If the amount of phosphate ions is less than 10 ppm, the corrosion resistance is lowered because the content of phosphate ions in the obtained chemical conversion coating is too low. If it exceeds 10,000 ppm, it cannot be expected to further improve its functional characteristics, and it is easy to form a precipitate. The aluminum ions mentioned above can be provided by aluminum fluoride, aluminum oxide, aluminum sulfate, aluminum silicate, aluminum silicate, aluminate such as sodium aluminate, etc., and fluoroaluminate acid such as sodium fluoroaluminate. Aluminum ions can also be obtained from aluminum heat sink materials. If the amount of aluminum ions is less than 100 ppm, the reaction of the chemical conversion coating layer cannot be promoted, resulting in a decrease in corrosion resistance; if the amount is more than 10,000 ppm, it will conversely prevent the formation of the chemical conversion coating layer and cause A precipitate was formed in the chemical conversion treatment solution. The effective fluoride ions mentioned above can be hydrofluoric acid, ammonium fluoride, hydrogen 8 1 Paper size Applicable to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page ) ----- I-^ ------ I-- 510832 ___ B7___ V. Description of the invention (h) Ammonium fluoride, sodium fluoride, sodium hydrofluoride, etc. are provided. When used as described above When the zirconium ion supplier is a fluoride-containing compound, such as fluorozirconic acid or ammonium fluorozirconate, the zirconium ion supplier also provides a part of the fluoride ion. Effective fluoride ion means the free fluoride concentration in the treatment solution. The effective fluoride ion concentration can be obtained by measuring the processing solution with a device containing a fluoride ion electrode. If the effective fluoride ion is less than 1 ppm, the surface of the heat sink material cannot be sufficiently etched, so that a sufficient amount of chemical conversion coating cannot be formed. If it exceeds 500 ppm, the aluminum ion concentration in the chemical conversion treatment solution will exceed the range of the present invention due to excessive etching, and the reaction will be hindered, and a large amount of precipitates will be formed at the same time. In order to further improve the corrosion resistance and moisture resistance, the treatment solution of the present invention contains an organic acid having at least one hydroxy group of phenol in the molecule at a concentration of 10 to 10,000 ppm. If its concentration is less than 10 ppm, the functional properties will be limited due to insufficient addition. If it exceeds 10, ⑻0 ppm, its functional characteristics cannot be further improved. Preferred organic acids include phenol, tannic acid and phenolic sulfuric acid. If the pH of the chemical conversion treatment solution is lower than 1.0, excessive corrosion will be caused, making it difficult to form a chemical conversion coating layer, and reducing the corrosion resistance. If it exceeds 4.0, it is also difficult to form a chemical conversion coating layer and reduce the corrosion resistance. The components of the chemical conversion treatment solution are analyzed, and the components of the solution are adjusted using a concentrated solution in accordance with the scope of the present invention. The treatment solution may contain other additives such as known inhibitors such as molybdic acid and tungstic acid, metal ions such as titanium, nickel, vanadium, hydrogen, iron and zinc, chemical conversion accelerators such as nitrite and hydrogen peroxide, and Clamping agent to maintain the aluminum ionization scale of 9 B.

After the aluminum heat sink material is subjected to the aforementioned chemical conversion treatment, it can be washed with water for 2 to 10 seconds, or extruded with a rubber roller, or the water can be similarly removed.

This means that the wastewater treatment load can be easily maintained and reduced. The better chemical conversion coating formed in this step also contains zirconium and phosphorus, each containing a content ranging from 1 to 100 mg / m2. If the amount is less than 1 mg / m2, the corrosion resistance will decrease unexpectedly. If it exceeds 100 mg / m2, the adhesion is unexpectedly reduced. In the next step, on the aforementioned chemical conversion coating layer, a corrosion resistant coating composed of a hydrophilic coating layer using a resin and / or a hydrophilic treatment aqueous solution containing a water-borne resin as a main component is formed.

The aluminum heat sink material produced by the above production method in the middle of the month has excellent weather resistance, humidity resistance, and adsorption, so it can be widely used in thermal systems such as air-conditioning systems and similar equipment. EXAMPLES Next, the present invention will be described in more detail by way of examples and comparative examples. Example 1 A chemical conversion treatment solution was prepared by adding fluoro acid, phosphoric acid and hydrofluoric acid in the same total amount. Individual concentrations are shown in Table 丨, and then 500 ppm of tannic acid and ammonia were added to adjust the pH 値 to 2. Zirconium, phosphoric acid, and aluminum ions were measured using Kyoto Koken's ICP; effective fluoride ions were measured using fluoride ions; and tannic acid was measured using TOC of Shimadzu Corporation to establish a calibration curve. Then, the aluminum heat sink material (JIS-A1100) was cut into 200 × 250 mm test specimens. These test pieces were sprayed with a degreaser (Surf Cleaner 340, product of Nippon Paint Co.) at a concentration of 1% by weight for 5 seconds at 70 ° C, and then rinsed with water. Using the above-mentioned chemical conversion treatment solution, the test piece was continuously subjected to chemical conversion treatment one by one at a temperature of 55 ° C, and the spraying time was 5 seconds. During the continuous chemical conversion treatment, the composition concentration of the treatment solution was gradually diluted. Therefore, in order to maintain the concentration of each component of the chemical conversion treatment solution, the solution was analyzed by composition16 (Please read the precautions on the back before filling this page) ----- III- · 11111111- This paper size applies Chinese national standards ( CNS) A4 specification (210 X 297 public love) 510832 A7 _____J7____ 5. Description of the invention (/ f) to monitor and adjust with concentrated liquid. As a result, aluminum ions were eluted from the test piece, gradually accumulated in the chemical conversion treatment solution, and finally reached a concentration of 1,000 ppm. To further increase the aluminum ion concentration, aluminum nitrate was dissolved therein, and the concentration of the constituent solution was 2,000 ppm. The test piece was treated with a solution having an initial composition and an aluminum ion concentration of 50, 200, 1,000, and 2,000 ppm, respectively, and then treated with a hydrophilic organic / inorganic composite modifier (Surf Alcoat 131, Nippon Paint Co.). In order to obtain hydrophilicity to prepare aluminum heat sink material, the method described below was used to evaluate the corrosion resistance and moisture resistance. As a result, satisfactory results were obtained in both corrosion resistance and humidity resistance at a concentration of aluminum ion not exceeding 200 ppm. The results are shown in Table 1. < Corrosion resistance > Salt spray test: The test piece was sprayed with a 5% sodium chloride aqueous solution at 35 ° C to evaluate the degree of white rust formation after 500 hours. ◎ No rust formation.
