Abstract

The invention relates to a manufacturing method of a single-face glazed aluminum alloy foil for drug use. The method comprises the following steps: using a roll-casting blank of an 8011 aluminum alloy material as the raw material, rolling the blank on a cold-rolling machine for a plurality of turns until 1.5 mm; performing the intermediate annealing at 400-550 DEG C for 10-30 hours; cold-rolling for two turns until 0.35 mm after the intermediate annealing and then cutting edges; after cutting edges, continuing rolling foil until 0.038-0.042 mm; combining two aluminum foils with the same thickness on a roller, dropping lubricant between two aluminum foils; and then foil-rolling to a finished product. The lubricant comprises the following components according to ratio by weight: 5-6% of simple lipid additive, 5-6% of single alcohol, 0.1-0.3% of dodecylic acid; and the rest is 80 # rolling oil. Through the preparation of the rolling oil with the reasonable oil product parameter and a stable rolling technique, the surface of the manufactured aluminum foil for drug use has high quality; the defects of bright spots on the dark face and black trace can be effectively eliminated; and the production efficiency and the finished product rate are improved.

Description

The manufacture method of the medicinal alloy foil of machine glazing
Technical field
The present invention relates to the manufacture of aluminium alloy foil material, specifically the manufacture method of the medicinal alloy foil of a kind of machine glazing.
Background technology
Current aluminium foil is widely used in Key works Drug packing, because medicinal aluminum foil packaging has the advantages such as protection against the tide, health, safety, convenience and long shelf-life, but because the technical requirement of producing medicinal aluminum foil is high, the general surface quality of medicinal alloy foil of current use is not good, there is the defects such as dark face bright spot and black silk, the continuation affecting the operations such as follow-up printing, coating is produced and uses.
Summary of the invention
Technical problem to be solved by this invention is, provides one can either improve medicinal alloy foil finished surface quality, reduce the defects such as dark face bright spot, can ensure again the manufacture method of mill speed, the medicinal alloy foil of the machine glazing of enhancing productivity.
The manufacture method of the medicinal alloy foil of machine glazing of the present invention is: with the cast-rolling stock of 8011 aluminum alloy materials for raw material, and on cold-rolling mill, the multiple passage of rolling is to 1.5mm, through 400 DEG C-550 DEG C intermediate annealing 10-30h; Be cold-rolled to 0.35mm trimming through two passages after intermediate annealing, continue paper tinsel after trimming and be rolled to 0.038-0.042mm, by aluminium foil pairing on milling train identical for two thickness, and lubricant on dripping between two aluminium foils, then paper tinsel is rolled to finished product;
The composition of described lubricant and weight ratio are: monoester additive 5-6%, single methanol additive 5-6%, laurate 0.1-0.3%, all the other are 80# ROLLING OIL.
The present invention is by preparing the ROLLING OIL of reasonable oil product parameter and stable rolling mill practice, and the medicinal aluminum foil surface quality produced is high, effectively eliminates the defects such as dark face bright spot and Hei Si, improves production efficiency and yield rate.
Detailed description of the invention
The inventive method manufactures in the embodiment of the medicinal alloy foil of machine glazing, and raw material adopts 8011 aluminium alloys, cast-rolling aluminum foil blank.The manufacturing step of medicinal aluminum foil is as follows:
Described cast-rolling aluminum foil blank is existed on the irreversible cold-rolling mill of four rollers after rolling four passages to 1.5mm through 400 DEG C-550 DEG C intermediate annealing 10-30h.Cold after intermediate annealing, arrange to 0.35mm trimming through two passage secondary cold-rollings, continue aluminium foil pairing on milling train identical for two thickness after trimming when paper tinsel is rolled to 0.038-0.042mm, and low-flash, low viscous pairing oil mix ROLLING OIL as lubricant on dripping between two aluminium foils, last paper tinsel is rolled to finished product thickness, as 0.02mm.The composition of described lubricant and weight ratio are: monoester additive 6%, single methanol additive 6%, laurate 0.3%, and all the other are 80# ROLLING OIL.
Detect through pilot production, the medicinal aluminum foil surface quality that the present embodiment produces is high, and eliminate the defects such as dark face bright spot and Hei Si, surface dynes value can reach more than 32, more than tensile strength 180MPa, more than tensile strength 150MPa after 240 DEG C of 75s bakings.
