Embodiment Construction

[0010] The manufacturing embodiment of aluminum foil for bottle cap of the present invention is as follows:

[0011] a. Smelting, casting and rolling, smelting and casting and rolling the raw materials, the thickness of the billet after casting and rolling is 7.0±0.3mm; the composition and weight percentage of the raw material alloy are: Si 0.6%, Fe 0.8%, Cu 0.1%, Mn 0.05%, Mg 0.05%, Cr 0.05%, Zn 0.05%, Ti 0.05%, Al balance.

[0012] b. Cold-roll the billet thickness to 3.0-6.0mm for uniform annealing of the billet. The annealing process is: under the condition of 550°C, keep warm for 25 hours; Intermediate annealing, the annealing process is: under the condition of 300 ℃, heat preservation for 20 hours;

[0013] c. Foil rolling, the aluminum strip after intermediate annealing is rolled through 2 to 3 passes to a finished product thickness of 0.17 to 0.24 mm.

[0014] The above-mentioned finished products have been tested, and the tensile strength is 140-180Mpa, the elongati...

Abstract

The invention relates to the manufacturing of aluminum alloy materials, in particular to an aluminum foil material for manufacturing an anti-fake bottle cover and a manufacturing method of the aluminum foil for the bottle cover. According to the invention, the aluminum foil material for the bottle cover comprises the following alloy components in percentage by weight: 0.55-0.65 % of Si (Silicon), 0.75-0.85 % of Fe (Ferrum), 0.03-0.15 % of Cu (Copper), 0.05 % of Mn (Manganese), 0.05 % of Mg (Magnesium), 0.05 % of Cr (Chromium), 0.05 % of Zn (Zinc), 0.05 % of Ti (Titanium) and the balance of Al (Aluminum). According to the invention, the material is optimized on the basis of the 8011 alloy, is integrated with the advantages of the 8011 alloy, has the advantages of high surface quality, high strength, good rupture strength and good rolling stability and can be used for effectively increasing the production efficiency and the yield. The aluminum foil material is completely comparable to hot rolled aluminum foil blanks in finished product quality and the rolling performance.

Description

technical field [0001] The invention relates to the manufacture of aluminum alloy materials, in particular to an aluminum foil material for bottle caps used for producing anti-counterfeit bottle caps and a method for manufacturing the aluminum foil for bottle caps. Background technique [0002] Aluminum anti-theft bottle cap is a new type of packaging material that is popular in domestic and foreign markets. Compared with traditional plastic bottle caps or tinplate caps, it is widely consumed for its good sealing performance, high pressure resistance, corrosion resistance, beautiful appearance, and environmental protection. favored by those. In addition to good deep drawing performance and low anisotropy, its manufacturing materials also require a certain baking strength after being cured by multiple color printing. At present, the aluminum alloys used to produce anti-theft covers on the market are generally 1100, 8011 and other alloys. Since the user has to carry out five...
