Air conditioner foil and preparation method thereof

Abstract

The invention discloses an air conditioner foil. The air conditioner foil comprises the following components of, in percentage by mass, 0.2% to 0.3% of Si, 1.4% to 1.5 % of Fe, less than or equal to 0.05% of Cu, 0.5% to 0.6 % of Mn, less than or equal to 0.05 % of Zn, less than or equal to 0.03 % of Ti, and the balance Al. The invention also discloses a preparation method of the air conditioner foil. The preparation method of the air conditioner foil comprises the following steps that, raw materials are subjected to smelting and cast rolling according to the components and the mass percentage;the cast-rolled blank is firstly subjected to homogenization annealing, then cold rolling is carried out, and finished product performance annealing is carried out after cold rolling; and a coatingcoats the surface of the finished product. According to the air conditioner foil and preparation method thereof, the machining performance is excellent, the strength is high, the plasticity is good and the flanging height is greatly increased, the problem of flanging cracking in the machining process of air conditioner foil fins is effectively avoided, the machining requirements of a high-speed punching machine are simultaneously met, and the machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to an air-conditioning foil and a preparation method thereof, and belongs to the technical field of aluminum foil calendering manufacturing.

Problems solved by technology

With the continuous improvement and optimization of air conditioner fin forming equipment and molds, the thinning of aluminum foil for air conditioners and the application of high-speed punching machines have become a necessary trend in the technological development of the air conditioner industry. Therefore, in order to be able to adapt to thinning and high-speed processing According to the application requirements, it is necessary to develop a high-performance aluminum foil for air conditioners that is better adapted to mold production. At present, the air conditioner foils at home and abroad are mainly 1100, 1200, 8011, and 3102 alloys, and the 1100, 1200, and 8011 air conditioner foils have better extensions. High rate, high flanging height, etc., but the strength of the alloy material is insufficient, and the material is soft. Flanging cracks and poor feeding have occurred during high-speed punching processing, while 3102 alloy has relatively good strength and can adapt to high-speed punching machines. The processing can properly improve the production efficiency, but due to the limitation of the alloy composition, the alloy is only suitable for the fin type with low flanging height during use, and it is prone to cracking when the air conditioner foil is thinned
