Description

Technical Field

[0001] The utility model relates to the technical field of optical materials, in particular to a new type of light-shielding material. Background Art

[0002] In some optical experimental situations, such as when it is necessary to test the light transmittance of related materials, the interference of ambient light on the experiment must be eliminated first, so the experiment needs to be carried out in a completely light-proof operating box.

[0003] In the related prior art, the shading materials used to make the operating box need to have a certain thickness to ensure its shading performance, and are mostly made of metal materials, which makes the operating box as a whole bulky and inconvenient to carry. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of shading material, which solves the problems existing in the prior art and can achieve excellent shading performance with a relatively thin material thickness.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A new type of shading material comprises a release film, a first layer stacked on the upper surface of the release film, and at least one second layer stacked in sequence on the upper surface of the first layer; the first layer is a 3M adhesive layer; the second layer comprises a first layer, a second layer, a third layer and a fourth layer stacked in sequence; the material of the first layer is Ti; the material of the second layer is SiO2 or MgF2; the material of the third layer is Ti3O5; the material of the fourth layer is SiO2 or MgF2; the thickness of the first layer is 3 to 200 nm, the thickness of the second layer is 3 to 100 nm, the thickness of the third layer is 3 to 100 nm, and the thickness of the fourth layer is 3 to 100 nm.

[0007] The first layer includes a back adhesive layer stacked on the upper surface of the release film, and a 3M foam layer stacked on the upper surface of the back adhesive layer.

[0008] Preferably, the 3M foam layer is black 3M foam.

[0009] The second layer and the fourth layer are made of the same material.

[0010] After adopting the above technical solution, the utility model has the following technical effects:

[0011] The utility model uses a second layer of shading material made of specific material, and a first layer made of 3M adhesive layer, which can be conveniently pasted on the surfaces of different objects that need shading, thereby achieving an excellent shading and light blocking effect. It is especially suitable for optical experiments that require perfect shading, and can effectively avoid the influence of ambient light on the experiment. The material of the utility model is relatively thin, light in texture, easy to cut and can be arbitrarily pasted on any position that needs shading, such as being pasted on the surface of an acrylic box to turn it into a black operating box with excellent shading performance, which is easy to use.
