Abstract
Provided is an aluminum foil according to the present invention including: a primer coated layer (13) which is formed by depositing a primer coating liquid on a non-glossy surface of the aluminum foil (11), and drying the primer coating liquid deposited on the non-glossy surface of the aluminum foil at temperature of 20 to 110° C. to then cool the same at temperature of 0 to 20° C.; a mid-coat layer (15) which is formed by depositing the mid-coating liquid on the upper portion of the primer coated layer (13); and a two-coat layer (17) which is formed by depositing the coating liquid on the upper portion of the mid-coat layer (15), and plasticizing the coating liquid deposited on the upper portion of the mid-coat layer for three to five minutes at temperature of 60 to 430° C.
Claims6
An aluminum foil having a glossy surface and a non-glossy surface, the aluminum foil comprising:
- a primer coated layer which is formed by depositing a primer coating liquid on a non-glossy surface of the aluminum foil, and drying the primer coating liquid deposited on the non-glossy surface of the aluminum foil at temperature of 20 to 110° C. to then cool the same at temperature of 0 to 20° C.;
- a mid-coat layer which is formed by depositing the mid-coating liquid on the upper portion of the primer coated layer;
- and
- a two-coat layer which is formed by depositing the coating liquid on the upper portion of the mid-coat layer, and plasticizing the coating liquid deposited on the upper portion of the mid-coat layer for three to five minutes at temperature of 60 to 430° C.,
- wherein the mid-coating liquid comprises a mixture of fluoroplastic dispersion liquid, pigment, pearl, a surface active agent and distilled water.
A method of manufacturing an aluminum foil, the aluminum foil manufacturing method comprising:
- a one-coat primer coated layer formation step of depositing a primer coating liquid on the surface of the aluminum foil, in order to form a one-coat primer coated layer;
- a hardening step of hardening the primer coated layer by cooling the aluminum foil on which the primer coated layer has been formed at 0 to 20° C. after having dried the aluminum foil on which the primer coated layer has been formed at 20 to 110° C.;
- a mid-coat layer formation step of depositing a mid-coating liquid on the upper portion of the primer coated layer, in order to form a mid-coat layer;
- a two-coat layer formation step of depositing a two-coat liquid on the upper portion of the mid-coat layer, in order to form a two-coat layer sequentially;
- and
- a plasticizing step of plasticizing the aluminum foil on which the mid-coat layer and the two-coat layer have been sequentially formed at 60 to 430° C. for three to five minutes, in order to harden the mid-coat layer and the two-coat layer.
