Abstract

A frame includes a substrate, a first priming paint layer, a second priming paint layer, a non-conductive vacuum metallized priming paint layer, and a non-conductive vacuum metallized coating layer. The substrate is made by die casting technology of metal powder. The substrate, the first priming paint layer, the second priming paint layer, the non-conductive vacuum metallized priming paint layer, and the non-conductive vacuum metallized coating layer are stacked in the order written. The disclosure also provides a surface treatment method for the frame.

First claim

What is claimed is:

1. A frame comprising:
a substrate made by die casting technology of metal powder;
a first priming paint layer made of polyurethane primer;
a second priming paint layer made of polyurethane primer;
a non-conductive vacuum metallized priming paint layer made of polyurethane primer;
a non-conductive vacuum metallized coating layer made of indium or stannum for providing specular highlight effect;
wherein the substrate, the first priming paint layer, the second priming paint layer, the non-conductive vacuum metallized priming paint layer, and the non-conductive vacuum metallized coating layer are stacked in sequence thereof; the frame further comprises a colored well lacquer layer formed on a surface of the non-conductive vacuum metallized coating layer facing away from the non-conductive vacuum metallized priming paint layer for providing color to the frame.

2. The frame of claim 1 , wherein the colored well lacquer layer has a thickness of 6 μm to 10 μm.

3. The frame of claim 1 , wherein the frame further comprises a finish paint layer formed on a surface of the colored well lacquer layer facing away from the non-conductive vacuum metallized coating layer.

4. The frame of claim 3 , wherein the frame further comprises an optical coating layer sandwiched between the colored well lacquer layer and the finish paint layer.

5. The frame of claim 3 , wherein the finish paint layer has a thickness of 20 μm to 25 μm, and is made of silicon dioxide or titanium dioxide.

6. The frame of claim 1 , wherein the first priming paint layer has a thickness of 8 μm to 12 μm.

7. The frame of claim 1 , wherein the second priming paint layer has a thickness of 25 μm to 30 μm.

8. The frame of claim 1 , wherein the non-conductive vacuum metallized priming paint layer has a thickness of 6 μm to 10 μm.

9. The frame of claim 2 , wherein the non-conductive vacuum metallized coating layer has a thickness of 50 nm to 200 nm, and is made of indium or stannum.
