Definitions
- the present invention relates to a method for producing a material used for a two-piece can produced by a process including drawing and ironing. More specifically, a two-piece can with a thin can wall can be formed by processing including squeezing and ironing, which does not require cooling or lubrication with water or an aqueous lubricant, and does not require cleaning of the can after making.
- the present invention relates to a method for producing a resin-coated aluminum alloy sheet for a drawn and ironed can coated with a thermoplastic resin, which is suitable for production.
- DI cans (Drawn and Ironed Can), which are obtained by drawing and ironing a tinplate or aluminum alloy plate, have been manufactured as a two-piece can in which the can body and the bottom of the can are integrally formed. I have.
- the DI can is tinned or drawn from an aluminum alloy plate, then cooled and lubricated with a large amount of water or a water-based lubricant using several successively arranged ironing dies and punches, and the wall thickness of the can is reduced. Is thinned to about 1/3 of the original thickness, then degreased, washed, dried and painted.
- Hei 6-311223 discloses a method of manufacturing a two-piece can from a resin-coated metal plate by a combined processing method including drawing and ironing. This method differs from the conventional method for manufacturing DI cans in that a resin-coated metal plate coated with a high-temperature volatile lubricant is drawn and then re-drawn in a dry manner without using water or an aqueous lubricant.
- a two-piece can with a thin can wall is manufactured by a combined machining method that involves simultaneous grinding. According to this combined processing method, the steps of degreasing, washing, drying, and painting the cans after they are formed into two-piece cans become unnecessary, and it is possible to manufacture two-piece cans with almost no pollution of the environment.
- the present invention has been studied for the purpose of providing a resin-coated aluminum alloy sheet suitable for this combined working method.
- materials suitable for the combined machining method Japanese Patent Application Laid-Open No. Hei 7-2666496 discloses materials with limited yield strength, tensile strength, plate thickness, center line roughness, and the like. 0 0 4 H 1 9 The use of an aluminum alloy is shown.
- An object of the present invention is to provide a resin-coated aluminum alloy sheet suitable for a combined machining method as disclosed in Japanese Patent Application Laid-Open No. 6-31223.
- the composite processing method to which the present invention is directed is a processing method in which redrawing and ironing are performed simultaneously using a die having a pair of a redrawing part and an ironing part.
- One of the features of the combined machining method is to reduce the dimension of the shoulder radius of the die where redrawing is to be performed, and to bend and bend back the material at this die shoulder radius to reduce the thickness of the can wall
- severe bending and unbending are performed with a small die shoulder radius that is about 2 to several times the thickness of the plate 2 to be machined, so that the surface of the material is likely to be rough and cracked.
- a can wall break occurs at the die shoulder radius. Even in the case where no fracture occurs at the die shoulder radius, rough skin and surface cracking cause a decrease in the adhesion between the coated resin coating and the aluminum alloy plate, and extremely breakage of the can wall occurs during subsequent ironing. It will be easier.
- the present invention relates to a resin which is resistant to can wall breakage and has the strength required for a can when performing dry / combined processing including bending and unbending at a die shoulder radius of a small shoulder radius and subsequent ironing.
- the task is to guide the coated aluminum alloy plate.
- the JIS aluminum alloy 304 H19 described in the examples of Japanese Patent Application Laid-Open No. Hei 7-2666496 has the required strength, but the workability is an object of the present invention. Is insufficient. Disclosure of the Invention
- Mn 0.5 to 2.0%
- Mg 0.2 to 2.0%
- Si 0.05 to 0.4% by weight%

And then a continuous annealing step, and then a cold rolling at a rolling ratio of 60 to 95%, followed by a surface treatment step.
- the surface-treated aluminum alloy sheet is subjected to a heat treatment at 240 to 350%.
- This is a method for producing a resin-coated aluminum alloy plate for ironing cans.
- Mn 0.5 to 2.0%
- Mg 0.2 to 2.0%
- Si 0.05 to 0.4% by weight
- Fe ⁇ 0.7% as inevitable impurities.
- thermoplastic resin to be coated is a thermoplastic polyester resin
- surface treatment applied to the aluminum alloy plate is etching and / or electrolytic chromic acid treatment, and furthermore, It is characterized by acid chromate treatment.
- the present invention has been extensively studied in order to provide a method for producing a resin-coated aluminum alloy sheet having excellent strength, workability, and adhesion, and excellent dry drawability and ironing workability.
- a manufacturing method that can obtain the target resin-coated aluminum alloy plate.
- A1-Fe-Mn-based crystallized substances have a lubricating effect during ironing and are indispensable for improving ironing workability.
- the present invention In this case, since an aluminum alloy plate whose surface is coated with resin is processed, the lubricating action of the Al-Fe-Mn-based crystallized substance is not necessary, but rather the workability is impaired.
- the crystallized product is not suitable for the combined working method for applying the resin-coated aluminum alloy sheet of the present invention.
- the combined machining method redrawing and ironing are performed simultaneously using a die with a pair of redrawing and ironing parts, and the shoulder radius of the redrawing die is a small shoulder radius that is several times the sheet thickness or less.
- the crystallized material significantly impairs the bending-unbendability at the die shoulder radius. In other words, during bending and unbending, the surface of the aluminum alloy is easily roughened and cracked, which lowers the adhesion of the coated resin film.
- the can wall may be broken.
- the A1-Fe-Mn-based crystallized substance is not preferable for the present invention, and it is desirable to minimize the amount.
- Mg is an element that is more effective than Mn in improving strength. Add 0.2% or more to obtain the strength required for the can, mainly the pressure resistance of the can bottom. Mg is an expensive element, and as the amount of addition increases, the formability deteriorates. Therefore, the upper limit is 2% from the viewpoints of formability and economy.
- the two-piece can formed by molding the resin-coated aluminum alloy plate according to the present invention using the above-described composite coating is applicable to contents where the internal pressure of the can is positive, such as beer, carbonated beverages, and nitrogen-filled beverages. If the bottom strength is insufficient, the can bottom will buckle and become unusable as a product. The bottom strength is mainly affected by the yield strength and thickness of the sheet. If the yield strength is low, it is necessary to increase the sheet thickness, which impairs economic efficiency.
- the Si causes a phase transformation in the A1-Fe-Mn-based crystallized material to form a so-called hard phase.
- this ⁇ phase needs to be added in an amount of 0.1% or more, but for the present invention, the bending and bending back workability is higher than that of the crystallized material before the phase transformation. Is not preferred. Therefore, the lower limit is set to 0.05% from the viewpoint of strength increase, and the upper limit is set to 0.4%, preferably 0.2% or less from the viewpoint of workability.
- Fe forms an A1-Fe-Mn crystallized substance in relation to Mn.
- the Al—Fe—Mn system is not preferable for the present invention from the viewpoint of bendability / bendback workability as described above, and the upper limit of Fe, which is a forming element thereof, is 0.7%. Preferably it is 0.4% or less.
- the upper limit of the amount of (S i + F e) is also determined in order to keep the amount of Al-Fe-Mn-based crystallization, especially the amount of hard ⁇ -phase, at a low level.
- the upper limits of the amounts of Fe and Si are determined as described above, but if each is near the upper limit, the A1-Fe-Mn system crystallization impairs the workability. Therefore, the upper limit is set to 0.9%, preferably 0.5% or less.
- Cu shows precipitation hardening due to A1-Cu-Mg-based precipitates together with Mg, and is effective from the viewpoint of increasing strength.
- the upper limit is preferably 0.4% or less in order to reduce the concentration.
- the addition of Zn has an effect of appropriately dispersing crystallized substances, and is preferably contained in an amount of 0.01 to 0.5% in order to reduce the adverse effects of the crystallized substances.
- An aluminum alloy having the above-mentioned chemical components is melted and manufactured by a conventional method, and the obtained agglomerate is subjected to a homogenizing heat treatment before hot rolling.
- This homogenization heat treatment aims at homogenization of micro deflection and precipitation of supersaturated elements, homogenization of the material, and improvement of hot rolling properties thereafter. If the temperature is less than 500T: the effect is insufficient, and if it exceeds 600 ° C, the performance of the board surface will be reduced due to burning and the like.
- the holding time in the above temperature range is preferably 1 hour or more.
- hot rolling is performed by a conventional method.
- the temperature during hot rolling is not particularly limited, but the hot start temperature is preferably in the range of 400 to 520, and the finish rolling temperature is preferably in the range of 230 to 350 ° C.
- the heating rate and the cooling rate when performing continuous annealing are preferably 10 o: z minutes or more. If it is less than 10 o: / min, the crystal grains become coarse, resulting in insufficient strength and workability.
- the heating temperature is 400 to 58 Ot :. If it is less than 40, recrystallization is insufficient and workability is not improved.
- the temperature exceeds 580 ° C, the surface of the plate is burnt, and the surface properties are deteriorated. Also, if the heating is performed for more than 5 minutes, the material softens and the required strength cannot be obtained.
- the temperature is kept at a temperature of 300 to 400 ° C. for 30 minutes to 5 hours, and then gradually cooled. If the heating temperature is lower than 300, recrystallization is insufficient. On the other hand, if it exceeds 4001: the crystal grains become abnormally coarse, which is not preferable. If the soaking time is less than 30 minutes, the inside of the coil will be insufficiently heated. If the heating time exceeds 5 hours, it will not only be uneconomical but will also become extremely soft, which is not preferable.
- the rolling ratio is preferably in the range of 60 to 95%. After cold rolling under these conditions, heat treatment is performed at 240 to 35 for 1 minute or less. As the rolling ratio increases, the crystallized material is stretched in the rolling direction, voids are formed around the crystallized material, and processing strain is accumulated, thereby deteriorating bending and unbending workability. Therefore, the upper limit of the rolling ratio is set to 95% from the viewpoint of workability. In order to obtain the required strength, the lower limit of the rolling reduction is set to 60%. Before coating the resin after the surface treatment, heating is performed at 240 to 350 for 1 minute or less in order to recover the reduction in workability due to the above-mentioned rolling.
- the lower limit of the heating temperature is 240 ° C for recovery, and the upper limit is 350 ° to prevent recrystallization. If the heating time becomes longer, the heating equipment becomes longer, and the required strength cannot be obtained due to the progress of softening. Heating is performed immediately before the resin coating step, and after heating to the above temperature, it is economical to coat the resin at a predetermined temperature in the cooling process.
- the aluminum alloy plate After being subjected to the above cold rolling, the aluminum alloy plate is subjected to a surface treatment by a known method such as anodizing treatment, immersion chromic acid treatment, phosphoric acid chromate treatment, etching treatment with an alkali solution or an acid solution, and electrolytic chromic acid treatment.

- the thickness of the laminated resin film is preferably in the range of 5 to 50 x m, more preferably in the range of 10 to 30 / m. When the thickness is less than 5 m, it is difficult to continuously laminate the metal plate at high speed. On the other hand, if the thickness of the laminated resin film is 50 ⁇ or more, it is not preferable in terms of economic efficiency as compared with an epoxy resin paint widely used as a material for cans.
- the resin film may be directly laminated on the aluminum alloy plate, or may be laminated with a thermosetting adhesive such as an epoxy-phenol resin interposed between the resin film and the aluminum alloy plate. Apply thermosetting adhesive to resin film or By pre-applying one of the luminium alloy plates to one side to be bonded to each other, the resin film can be laminated on the aluminum alloy plate with a thermosetting adhesive interposed therebetween.
- a thermosetting adhesive such as an epoxy-phenol resin interposed between the resin film and the aluminum alloy plate.
- the temperature of the aluminum alloy plate when coating the resin film varies depending on the type of resin to be coated, but is set to 220 to 300 ° C. Below 220, when the obtained resin-coated aluminum alloy plate is drawn and ironed, the resin film coated with poor working adhesion is easily peeled off. On the other hand, above 30 Ot :, the resin film to be coated melts and adheres to a laminating roll or the like, and the coating operation becomes impossible. For the above reasons, the upper and lower limits of the temperature of the aluminum alloy plate when coating the resin film are determined.
- thermoplastic resin film is brought into contact with both sides of the aluminum alloy plate heated to the above temperature, superimposed between a pair of laminating rolls, sandwiched and pressed, and immediately the thermoplastic resin is pressed. Cool rapidly below the recrystallization temperature. From the above steps, a resin-coated aluminum alloy plate for a drawn and ironed can is obtained.

- the properties of the lubricant to be applied those having a melting point in the range of 25 to 80 and a boiling point in the range of 180 to 400 are desirable for achieving the object of the present invention.
- the amount of application should be determined in consideration of the outer surface of the can, the inner surface of the can, processing conditions, heating conditions after processing, etc., but 5 to 100 mg / m, preferably 30 to 100 mg / m.
