Abstract

Disclosed is a method for manufacturing a light-reflection aluminum door frame molding which comprises a multi-coating-applied aluminum material to thereby improve corrosion resistance and reduce costs. A method for manufacturing a light-reflection aluminum door frame molding includes cutting a metallic plate into a predetermined size, performing anodizing on the metallic plate to form an oxidized film on a surface thereof, performing opaque clear coating and transparent coating on the metallic plate to implement light reflection, and performing press molding on the metallic plate to provide the metallic plate in the shape of a door frame molding.

First claim

What is claimed is:

1. A light-reflection aluminum door frame molding formed by a method comprising:
cutting a metallic plate into a predetermined size and performing anodizing on the metallic plate to form an oxidized film on a surface of the metallic plate;
performing a primary clear coating and a second clear coating sequentially on the metallic plate to provide light reflection; and
performing press molding on the metallic plate to provide the metallic plate in the form of the light-reflection aluminum door frame molding,
wherein the light-reflection aluminum door frame molding comprises the metallic plate, the oxidized film formed on the surface of the metallic plate, the primary clear coating layer formed on the oxidized film and the secondary clear coating layer sequentially formed on the primary clear coating layer, and
wherein the primary clear coating layer is formed with a binder and a matting agent added to the binder thereby being formed opaque or semi-transparent, and the secondary clear coating layer is formed with the binder only thereby being transparent.

2. The door frame molding of claim 1 , wherein the metallic plate is made of an aluminum material.

3. The door frame molding of claim 1 , wherein a thickness of the oxidized film after anodizing is about 1-3 μm.

4. The door frame molding of claim 1 , wherein the clear coating is carried out as a continuous process using one or more rollers and, as roll coating conditions, a speed of about 5-7 m/min and a temperature of about 50-70° C. are maintained.
