Problems solved by technology

[0004] The existing aluminum foil production process is not high in precision, and the produced aluminum foil is difficult to meet the actual production requirements. At the same time, the aluminum foil itself is easy to oxidize and the color becomes dark, which is not conducive to the hot stamping of long-term preservation of book covers, etc.

Abstract

The invention discloses a production process for aluminum foil. The production process comprises the following steps that 1235 alloy, pure aluminum ingots, iron ore, silicon, copper ore and zinc ore are added into an ore crusher to be crushed, and a metal fine powder mixture is obtained; the metal fine powder mixture is poured into a stirring reaction container, then polyvinyl alcohol and a thickening agent are added, and stirring is conducted to obtain an aluminum foil production raw material; and the aluminum foil production raw material is subjected to rolling and annealing multiple times to obtain an aluminum foil roll, and the aluminum foil roll is slit to obtain the finished aluminum foil. According to the production process, the 1235 alloy, the pure aluminum ingots, the iron ore, the silicon, the copper ore, the zinc ore, the polyvinyl alcohol and the thickening agent are adopted as the aluminum foil production raw material, rolling and annealing are conducted multiple times inthe production process, the prepared aluminum foil meets the actual production requirements, has very high ductility and hardness, is not prone to oxidation, facilitates long-term storage of book written hot stamping, and has wide market prospects.

Description

technical field [0001] The invention relates to the technical field of aluminum foil production, in particular to an aluminum foil production process. Background technique [0002] Aluminum is a silvery-white light metal with ductility. Products are often made into rods, flakes, foils, powders, ribbons and filaments. In humid air, an oxide film can be formed to prevent metal corrosion. Aluminum powder can burn violently when heated in the air, and emit a blinding white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. The relative density is 2.70. The melting point is 660°C. The boiling point is 2327°C. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the earth's crust. The development of the three important industries of aviation, construction, and automobile requires that the material pr...
