Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

The utility model relates to a metal anti-dazzling screen, including the shading body 1 of metal material and the copper layer 2 of setting on shading body 1 surface.

The light shielding body 1 comprises a first surface 11 and a second surface 12 which are parallel, and an inner annular surface 13 and an edge surface 14 which are connected between the first surface 11 and the second surface 12, wherein the first surface 11, the second surface 12 and the inner annular surface 13 are all formed into roughened surfaces by chemical etching;

the copper layer 2 is formed on the first surface 11 and the second surface 12 by plasma plating and is blackened by a chemical wet method.

Referring to fig. 1, a specific embodiment of the present invention is shown.

The shading body 1 is made of stainless steel (SUS), so that the utility model has a longer service life.

The inner ring surface 13 forms an arc angle structure through chemical etching, the included angle theta between the tangent line of any position and the optical axis of the shading body 1 meets the condition that theta is more than or equal to 60 degrees and less than or equal to 80 degrees, the reflection area of the inner ring surface 13 is effectively reduced, and the larger the theta angle is in the range, the smaller the reflection area is, and the better the glare eliminating effect is; the inner ring surface 13 adopts an arc angle structure, and finally, a reflecting light source is focused into point source reflection, so that a better reflecting effect is achieved.

The edge surface 14 is square or circular to accommodate different shade installation requirements. When the edge surface 14 is circular, the inner diameter D1 of the light shielding body 1 ranges from 0.3 mm to 9.2mm, and the outer diameter D2 ranges from 1mm to 10 mm.

The thickness H1 of the shading body 1 ranges from 0.01 mm to 0.1 mm.

The thickness H2 of the copper layer 2 ranges from 5 to 20 mu m, the thickness of the copper layer 2 is not increased after the copper layer is subjected to chemical wet process black dyeing, the reflectivity of the copper layer 2 is less than 2 percent after the copper layer is blackened, and the surface roughness R is_Z≥0.58μm。

The copper layer 2 is formed in a wet chemical blackening agent, and the copper blackening salt is strongly alkaline.

Referring to fig. 2, after copper plating and black dyeing, the reflectivity of the light-shielding body 1 is less than 2% under the wavelength light of 400-700 nm, and the light-shielding body is black; in contrast, when the light-shielding sheet is an existing uncoated optical SUS stainless steel, the average reflectance in the visible light effective spectral region is about 25% to 35%, and thus, the reflectance of the light-shielding body 1 after copper plating is greatly reduced.
