Description of the invention: I: Technical field of the invention of the invention 3 Field of the invention The present invention relates to a kind of chemical-resistant, flat portion of a metal plate, and the processing of the metal plate and the end face An aqueous coating composition of a coating film having excellent surname and adhesion and a coated metal sheet having a coating film formed of the aqueous coating composition. I. Prior Art 3 Background of the Invention In the past, precoated steel sheets coated with coil coating or the like have been widely used as roofs, walls, and shutters of buildings. Shutters, garages Such as building materials, residential products related to various home appliances, switchboards, refrigerated display cabinets, steel furniture and kitchen appliances. In the case of these residential-related products made of pre-coated metal sheets, the pre-coated metal sheets are usually cut and joined by press molding. Therefore, in many of these residential related products, there are many metal exposed portions of the cut surface or crack generating portions due to the press working #. Since the metal exposed portion or the crack generating portion is more likely to have lower corrosion resistance than other portions, it is generally practiced to use a chromium-based rust-preventing pigment in the undercoat coating film which is used for the pre-coated metal sheet to improve corrosion resistance. However, chromium-based rust-preventive pigments or hexavalent chromium which is excellent in rust-preventing properties may generate hexavalent chromium. The hexavalent chromium poses a problem from the viewpoint of the health of the human body and environmental protection. Up to now, non-chromium anti-rust pigments have been produced on the market, such as zinc phosphate, tripolyphosphate 201012881 acid, zinc acid, etc. As a primer for combining non-chrome pigments, various products have been put forward. In addition, in order to reduce volatile organic compounds (v〇c) from environmental issues, the development of waterborne coatings has been demanded. For example, Patent Document 1 discloses an anti-rust pigment in which a combination of an epoxy resin and a phenolic resin is mixed, a combination of calcium citrate and phosphorus vanadate, or calcium carbonate and calcium silicate with aluminum phosphate and vanadium. A coating made of a combination of acid and phosphorus anti-rust pigments. Further, Patent Document 2 discloses that a phosphoric acid is mixed in a polyacetate; a flag and a manganese oxide. A vanadium oxide sintered product is used as a coating for a rust preventive pigment, and a coating of calcium iodate and vanadium oxide is mixed. However, when the rust-preventive pigments described in Patent Documents 1 and 2 are applied to an aqueous coating material, the corrosion resistance is weaker than that of the coating material using the chromium-based pigment, and the corrosion resistance of the processed portion and the end surface portion of the metal sheet is insufficient. In addition, there are cases in which chemical resistance such as alkali resistance or acid resistance or <aqueous property is poor. Further, Patent Document 3 describes a coating composition which contains an oil absorption amount of 3G to 2 〇Gml/lGGg and a pore volume 在 in an organic resin containing a secret or epoxy group and a color-developing enamel component. 〇5~丨2ml/g of the coating of the dioxide fine particles, and the glass transition/dish of the hardened coating film formed by the coating is in the range of 4 〇 to 125 ° 。. However, the coating film obtained by applying the cerium oxide microparticles contained in Patent Document 3 to an aqueous coating has poor resistance to surnames and chemical resistance, especially in the end face of the metal sheet. . Patent Document 4 discloses a chromium-free coated steel 201012881 plate excellent in corrosion resistance, characterized in that it is mixed with magnesium phosphate, zinc phosphate, magnesium hydrogen phosphate, aluminum dihydrogen phosphate, calcium citrate. A primer coating film of one or two kinds of non-chromium-based rust-preventive pigments and a partial hydrolysis-condensation product of tetra-alkoxysilane mixed with a topcoat coating film of a hydrophilic agent 'According to the surface of the coating. Further, Patent Document 5 discloses an internally gelled hard polymer particle (a) containing an average particle diameter of 44 to 0.6 μm, water-dispersible cerium oxide (b), glycidyloxyalkyl group- Glycidoxyalkyl trialkoxysilanes (c), organic hunger compounds (d), water-dispersible urethane resin (e), wrong compounds (f) and acid-filled gas (g) The water-based anti-rust coating composition is coated with a galvanized steel sheet. However, the coating film obtained by coating the coating material containing the rust preventive pigment described in Patent Document 4 or Patent Document 5 is inferior in corrosion resistance and chemical resistance as compared with the coating film obtained by coating a coating material containing a chromium-based pigment. In particular, the resistance of the end face of the metal plate is insufficient. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei.

(c) The amount of the additive effect may be added. The pigment dispersion resin may be a known one. For example, a base resin containing a hydroxyl group and a cationic group, or a tertiary amine type epoxy resin or a quaternary ammonium salt may be used. The resin used for the pigment dispersion resin is used in an amount of 1 to 150 parts by mass per 100 parts by mass of the pigment component, and particularly (7) is called (8) parts by mass. The coloring pigment may, for example, be an organic coloring pigment such as an organic red pigment such as phthalocyanine blue, phthalocyanine green, azo or quinacridone; titanium white, titanium yellow, and iron dan In particular, titanium black may be suitably used among the inorganic black pigments such as carbon black and various sintered pigments. The above-mentioned extender pigments may, for example, be talc, dry earth, silica dioxide mica, alumina, calcium carbonate, barium sulfate. Wait The amount of the coloring pigment and the extender pigment is not particularly limited, and it is, for example, 1 to 100 parts by mass per 100 parts by mass of the total solid content of the cationic resin (A) and the polyisocyanate curing agent (B), respectively. The above organotin compound may suitably use dibutyl tin dibenzoate, dioctyltin oxide, dibutyltin oxide, etc. The organic solvent is used to improve the aqueous coating composition of the present invention. An organic solvent capable of dissolving or dispersing the cationic resin (A) and the polycyanate curing agent (B) may be used as the coating property, etc. Specific examples thereof include toluene and xylene. a hydrocarbon-based solvent such as a high-boiling petroleum hydrocarbon, a ketone solvent such as methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone or isophorone; ethyl acetate, butyl acetate, ethylene glycol monoethyl ether acetate, and An ester solvent such as ethylene glycol monoethyl ether acetate, an alcohol solvent such as methanol, ethanol, isopropanol or butanol, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether Ether Based solvent may be used singly or as a mixture of two or more use.

The aqueous coating composition can be adjusted by a water-adjusting method by using a pigment dispersion slurry containing the rust-preventive pigment mixture (C) as described above in the emulsion described above. 5. Coating film forming method The aqueous coating composition of the present invention can be obtained by coating a metal plate and hardening it. The coated metal plate can be exemplified by the aforementioned metal plate. In addition, the surface of these metal plates may be subjected to chemical conversion treatment (pretreatment). Fig. 1 is a schematic view showing a coating line when the aqueous coating composition of the present invention is used as a primer. Here, since the coating film obtained by coating the water-based paint composition of the present invention on the molten zinc-zinc steel sheet can be obtained without the chemical conversion treatment (pretreatment), it is excellent in the resistance (4), so in the coating (four) It is also possible to omit the procedure of the chemical conversion treatment (pre-treatment), and contribute to the saving of the process and the resource utilization. In addition, chemical conversion treatment (pretreatment) can be carried out as needed, for example, Wei salt treatment, composite emulsion membrane treatment, dish acid treatment, and complex acid treatment for zinc phosphate treatment or iron phosphate treatment. Wait. The coating of the aqueous coating composition of the present invention can be applied to the above-mentioned gold ❿ board by a roll coating method, a curtain coating method, a spray coating method, a brush coating method, and a dipping A known method such as a method is used for coating. The thickness of the cured film of the coating film obtained from the aqueous coating composition is not particularly limited, and is usually used in the range of 0.5 to ΙΟμηη, preferably 2 to 7 μm. The curing of the coating film can be appropriately set according to the type of the resin to be used, and when the coating film is applied by continuous coating or the like, 24 201012881 is the highest temperature at which the material reaches 100 to 250. °C, to achieve 180~230C for better conditions, sintering 15~6 〇 seconds. In the case of batch sintering, it can also be in the range of 80 to 200. (: Sintering 1 〇 to 3 〇 minutes. The aqueous coating composition of the present invention is coated on a metal plate, and the formed coating film is excellent not only in the flat portion of the metal plate but also in the processed portion and the end surface portion of the metal plate. Corrosion resistance. The reasons for this are as follows: 1. In the corrosive environment, 'metal ions generated by dissolution of metal ions due to chloride ions, etc.' and pentavalent vanadium ions (V (V or V043-) The vanadic acid ion directly forms a precipitated salt without undergoing a redox reaction, and the trivalent vanadium ion and the metal ion generated by the redox reaction of the pentavalent vanadium ion and the material metal are efficiently generated. The precipitated salt or the compound's material can effectively cover the material to expose the surface. In addition, it is considered that the phosphate ion is dissolved at the same time, so that the corrosion progressing portion and its periphery are adjusted to be particularly suitable for the pentavalent vanadium ion and the material metal. The pH range of the redox reaction. 2. The rust inhibitor in the aqueous coating composition is partially dissolved and exists in the state of metal ions. The waterborne coating composition is applied to the metal material and added. When the coating film is formed by thermal drying, the dissolved component is effectively reacted at the interface of the material metal, and an oxide film which functions as a chemical conversion treatment film is formed under the coating film. Further, even if the film is coated on the film In addition, it is possible to form a coating film having a function of protecting the damage (self-healing property) by eluting the metal ions of the rust-preventing pigment mixture (C) from the coating film. The formation of the above-mentioned "film and coating film", It can be obtained by one coat and heat drying, 25 201012881 This is presumably helpful for obtaining coated articles excellent in corrosion resistance. 3. By using the above-mentioned vanadium compound (cl) and citrate compound which constitute a mixture of rust preventive pigments (c2) and the phosphate-based calcium salt (c3) can effectively control the weak portions of the acid resistance, alkali resistance, and water resistance of each of the above (cl), (c2), and (C3). In a strong atmosphere where the material of the material exceeding pH 10 is easy to dissolve, it has the effect of inhibiting the dissolution of the metal of the material, so that excellent chemical resistance and water resistance can be achieved at the same time. The multiplication effect of the basic function exerts a great function, and it is inferred that this also contributes greatly to the excellent corrosion resistance of the water-based paint. Further, the glass transition temperature of the hardened coating film obtained from the aqueous paint composition of the present invention is 40~ 115 ° C, from the point of view of the corrosion resistance, acid resistance and processability of the coating film, 50 to 1 〇 5. (: is better. . . 'The glass transition temperature of the coating film is to use DINAMIC VISCO-EL ASTO METER MODEL VIBRON (Vibration type dynamic viscoelastic spectrometer) DDV-IIEA type (manufactured by ToyoBaldwin Co., automatic dynamic viscoelasticity meter) 'maximum value obtained from the variation of tan5 obtained by temperature dispersion measurement at a frequency of 110 Hz Value temperature ^ ❿ On the coating film obtained by sintering and drying the water-based paint composition, a top coat film may be provided as needed (see the film thickness of the top coat film in Fig. 2 is 5~ ΙΟμιη, with 10~50μιη as good. The above-mentioned top coat paint may, for example, be a known polyether-based resin, an alkyd resin, an oxime-modified polyester resin, or a linalo-modified acrylic resin. A topcoat paint such as a fluororesin or the like. The type of the top coat is not limited to the above types. In addition, in the case of 26 201012881, when processing is particularly important, a highly processed urethane-based topcoat can be used to obtain a coated metal sheet having particularly excellent workability. In addition, 'the use of mineral zinc steel plate and touch-zinc alloy steel plate as the t-plate of the coated object' is greatly improved in the flatness of the flat portion of the metal plate, but the technique of the s岫 is cut off at the end face and molded. The processing department and the financial department are insufficient. However, by coating the water-based paint composition of the present invention, it is possible to obtain a coating film which is excellent in resistance to the surname regardless of the flat portion, the end surface portion, and the processed portion of the metal sheet.

An aqueous coating composition of a coating film having excellent physical and chemical properties and adhesion to a processed portion of a metal sheet, and a coated metal sheet having a coating film formed of the aqueous coating composition. φ BACKGROUND OF THE INVENTION In the past, precoated metal sheets such as precoated steel sheets coated with coil coatings and the like have been widely used as building materials for roofs, walls, shutters, garages, etc. Use of home-related products such as home appliances, switchboards, refrigerated display cases, steel furniture, and kitchen appliances. In the case of these residential-related products made of pre-coated metal sheets, the pre-coated metal sheets are usually cut and joined by press molding. Therefore, in many of these residential related products, there are many metal exposed portions of the cut surface or crack generating portions due to the press working #. Since the metal exposed portion or the crack generating portion is more likely to have lower corrosion resistance than other portions, it is generally practiced to use a chromium-based rust-preventing pigment in the undercoat coating film which is used for the pre-coated metal sheet to improve corrosion resistance. However, chromium-based rust-preventive pigments or hexavalent chromium which is excellent in rust-preventing properties may generate hexavalent chromium. The hexavalent chromium poses a problem from the viewpoint of the health of the human body and environmental protection. Up to now, non-chromium-based anti-rust pigments have been produced in the market as a combination of non-chromium pigments, such as zinc phosphate and tripolyphosphate. In addition, from the environmental issues, the development of new low-VOC (real), water-based coatings has been demanded. For example, 'patent document 1 is written in a toner composition of an epoxy resin and a secret resin, (4) a combination of a material (four) phosphorus, or a mixture of a carbonated mother and a mixed contact Wei Ming and a __ Into the paint. Further, in Patent Document 2, it is described that a mixture of a bowl of acid and a oxidized smoldering sinter is used as a coating of a p-precipitated pigment, and a mixture of a dish of a sour mom and an oxidized coating is mixed. However, when the rust-preventive pigments described in Patent Documents 2 and 2 are applied to an aqueous coating material, the corrosion resistance is inferior to that of the processed portion and the end surface portion of the metal sheet as compared with the coating material using the chromium-based pigment. In addition, there is a case where the chemical resistance or the water resistance such as alkali resistance or acid resistance is poor. Further, Patent Document 3 describes a coating composition which is a toner component formed of an organic resin containing a hydroxyl group or an epoxy group and a curing agent, and has an oil absorption amount of 30 to 200 ml/100 g and a pore volume 〇. 〇5~i 2ml/g of the coating of cerium oxide microparticles, and the glass transition temperature of the hardened coating film formed by the coating is 40 to 125. However, in Patent Document 3, the coating film obtained by applying the coated cerium oxide particles to the aqueous coating has poor corrosion resistance and chemical resistance, especially in the coating material using the chromium-based pigment. In addition, Patent Document 4 discloses a chromium-free coated steel 201012881 plate excellent in corrosion resistance, characterized in that it is mixed with magnesium phosphate, zinc phosphate, hydrogen phosphate, A primer coating film of one or two or more kinds of non-stereoscopic rust-preventing pigments of dihydrogen-sodium dihydrogen phosphate, and a mixture of tetrahydrooxane and a partial hydrolysis-condensation product of Tetra- alkoxysilane as a topcoat coating film of a hydrophilic agent, which is laminated on the surface of the ore layer. Further, Patent Document 5 discloses an internally gelled hard polymer particle having an average particle diameter of 0.4 to 0.6 μm. ), water-dispersible cerium oxide φ (b), glycidoxyalkyl-trimethyl oxysilanes (c), organic vanadium compounds (d), water-dispersible urethane resin (urethane resi) n) (e), a zirconium compound (1), and a galvanized coating material having a water-borne anti-rust coating agent composition, which is treated with a hydrous sulphate (g), which is described in Patent Document 4 or Patent Document 5 The coating film obtained by the coating containing the rust-preventing pigment has poor corrosion resistance and chemical resistance as compared with the coating film obtained by coating the coating containing the chrome-based pigment, and particularly has insufficient resistance to the surname of the metal plate end face.

The method to paint. The thickness of the cured film of the coating film obtained from the aqueous coating composition is not particularly limited, and is usually used in the range of 0.5 to ΙΟμηι, preferably 2 to 7 μm. The curing of the coating film may be appropriately set depending on the type of the resin to be used, and when the coating film coated by the wire coating method or the like is continuously sintered, 24 201012881 is the highest temperature at which the material reaches 100 to 250°. c, to achieve 180~230C, preferably sintered for 15~60 seconds. In the case of batch sintering, it can also be sintered at 80 to 20 (TC for 10 to 30 minutes. The aqueous coating composition of the present invention is coated on a metal plate, and the formed coating film is formed not only on the flat portion of the metal plate, It also exhibits excellent corrosion resistance in the processed portion and the end surface of the metal sheet. The reason is as follows: L. In the corrosive environment, the metal ions generated by the dissolution of the material metal due to vapor ions or the like, and The pentavalent vanadium ion (vanadium ion of VCV or V043) does not undergo a redox reaction and directly forms a precipitated salt, and the trivalent vanadium ion and the material metal formed by the redox reaction of the pentavalent vanadium ion and the material metal Ion's and oxalic acid ions effectively form a stagnation salt or a compound. The material 'is effectively coated with the material to expose the surface. In addition, it is thought that it is because the acid ions of the dish are simultaneously dissolved, so that the site of the rot and its surroundings are It is adjusted to a pH range which is particularly suitable for the redox reaction of the pentavalent vanadium ion and the material metal. 2. The rust preventive agent in the aqueous coating composition is partially dissolved and exists in a metal ion state. When the material composition is applied to a metal material and dried by heating to form a coating film, the dissolved component is effectively reacted at the interface of the material metal, and an oxide film that functions as a chemical conversion treatment film is formed under the coating film. Further, even if the coating film on the film is damaged, it is possible to form a coating film having a function of protecting the damage (self-healing property) by eluting the metal ions of the anti-money pigment mixture (C) from the coating film. The formation of "film and coating film" can be obtained by one coating and heat drying, 25 201012881 & point speculation is very helpful for obtaining the excellent coated articles of Nike. By using the above-mentioned vanadium compound which constitutes a mixture of anti-money pigments (cl), Shishi compound (e2) and the disc acid salt 33 (6) can effectively control the weak portions of the acid resistance or the testability and the water property of each of the above () (c2) and (C3). 'Because calcium ions are more effective than the strong test medium in which the metal of the material exceeds pH 1 易于, it has the effect of inhibiting the dissolution of the metal, so it can achieve excellent chemical resistance and water resistance at the same time. The synergistic effects of the anti-money pigment mixture-based effects play a large role, and it is inferred that this is also helpful for the excellent resistance of the water-based paint. Further, the hardened coating film obtained from the aqueous paint composition of the present invention is further improved. The glass transition temperature is 40 to 115. (:, from the point of resistance of the coating film, acid resistance, and processability, 50 to i 〇 5t is preferable. The glass transition temperature of the coating film is Using DINAMIC VISC〇_ ELASTO METER MODEL VIBRON (Vibrator-type dynamic viscoelastic spectrometer) DDV-IIEA type (manufactured by ToyoBaldwin Co., automatic dynamic viscoelasticity meter), tan5 obtained by temperature dispersion measurement at a frequency of 110 Hz The maximum temperature obtained by the change. @ On top of the coating film obtained by sintering and drying the aqueous coating composition, a top coat film may be provided as needed (see Fig. 2). The film thickness of the topcoat film is 5~ ΙΟμιη, preferably 1〇~5〇μπι. The above-mentioned top coat paint may, for example, be a known polyester resin type, an alkyd resin type, a silicone modified polyester resin, a linalool modified acrylic resin type, or a fluorine as a precoated steel sheet. A top coat such as a resin. The type of the top coat is not limited to the above types. In addition, in the case of 26 201012881, when processing is particularly important, a highly processed urethane-based topcoat can be used to obtain a coated metal sheet having particularly excellent workability. In addition, when a plated steel plate or an aluminum-plated alloy steel plate is used as the metal plate of the object to be coated, the durability of the flat portion of the metal plate is greatly improved, but as of the technique of the month j, the cut end face and the passage are The processing department of the molding process is not enough for the money. However, by coating the water-based paint composition of the present invention, it is possible to obtain a coating film which is chemically resistant and which exhibits excellent durability irrespective of the flat surface of the metal plate and the processed portion.
