Reflective film capable of penetrating electronic signals

The technical field is as follows:

the utility model belongs to the technical field of reflective materials, in particular to a reflective membrane capable of penetrating electronic signals.

Background art:

retroreflective sheeting is a retroreflective material that has been made into films for direct use, and is also the most widely used retroreflective material. With the development of society, the popularization of automobiles and the electronic signal demand for reflecting materials are more and more strong, and the existing reflecting film has the property of reflecting light but cannot be applied to all occasions. The light reflecting property of the existing light reflecting film is usually realized by aluminum plating. However, the aluminum coating can shield the electronic signals, and the electronic signals of the reflective film are seriously influenced.

The invention content is as follows:

the utility model aims at providing a can not shield the reflective membrane of penetrable electronic signal that electronic signal carries out.

The utility model discloses a realize like this:

the utility model provides a penetrable electronic signal's reflective membrane, includes surface course, glue layer, titanium dioxide bisque and the pressure sensitive adhesive layer that from top to bottom sets gradually, the embedded glass bead layer that is equipped with of glue layer, the glass bead layer includes the glass microballon that a plurality of tiling set up, the bottom surface of glue has the spherical convex surface of quantity, position and glass microballon one-to-one, the top surface of titanium dioxide bisque is provided with the spherical concave surface of being connected with the laminating of every spherical convex surface.

In the reflective film capable of transmitting electronic signals, the surface layer is an acrylic resin surface layer.

In the above reflective film capable of penetrating electronic signals, the glue layer is an acrylic glue layer.

In the reflective film capable of transmitting electronic signals, the diameter of the glass beads is 75-85 μm.

In the reflective film capable of penetrating electronic signals, the refractive index of the glass beads is 1.9-1.95.

In the reflective film capable of transmitting electronic signals, the thickness of the surface layer is 40-60 μm.

In the reflective film capable of penetrating electronic signals, the thickness of the pressure-sensitive adhesive layer is 40-60 μm.

In the reflective film capable of penetrating electronic signals, the release paper is arranged on the bottom surface of the pressure-sensitive adhesive layer.

Compared with the prior art, the utility model outstanding advantage is:

the utility model discloses a titanium dioxide powder layer forms the interface with glass bead, and light forms the reflection at the interface for the reflective membrane possesses the attribute of reflection of light under the condition that does not use the layer of aluminizing, and the titanium dioxide powder layer can not shield the signal, has enlarged application scope, if: will the utility model discloses the laminating is on the metal sheet that has the chip, and inside information can also be discerned to the instrument.

Description of the drawings:

fig. 1 is a schematic cross-sectional view of the present invention.

In the figure: 1. a surface layer; 2. a glue layer; 3. glass beads; 4. a titanium white powder layer; 5. a pressure sensitive adhesive layer; 6. and (4) release paper.

The specific implementation mode is as follows:

the invention will now be further described with reference to specific embodiments, with reference to fig. 1:

the utility model provides a penetrable electronic signal's reflective membrane, this penetrable electronic signal's reflective membrane 1 is including the surface course, glue layer 2, titanium dioxide bisque 4 and the pressure sensitive adhesive layer 5 that from top to bottom set gradually, the embedded glass bead layer that is equipped with of glue layer 2, glass bead layer includes the glass microballon 3 that a plurality of tiling set up, there is the spherical convex surface of quantity, position and 3 one-to-ones of glass microballon in the bottom surface of glue layer 2, the top surface of titanium dioxide bisque 4 is provided with the spherical concave surface of being connected with the laminating of every spherical convex surface, and spherical concave surface forms the interface between glass microballon 3 and the titanium dioxide bisque 4, and light forms the reflection at this interface, makes the utility model discloses under the condition that does not set up the layer of aluminizing, still possess the attribute of reflection.

The utility model discloses pressure sensitive adhesive layer 5's bottom surface is provided with from type paper 6. Because pressure sensitive adhesive layer 5 has certain viscidity, when not using, the utility model discloses pressure sensitive adhesive layer 5's bottom surface is provided with from type paper 6. When in pasting, the release paper 6 is torn off.

Specifically, the surface layer 1 is an acrylic resin surface layer; the glue layer 2 is an acrylic acid glue layer; the diameter of the glass bead 3 is 75-85 μm, the refractive index of the glass bead 3 is 1.9-1.95, and the specific refractive index can be arbitrarily selected within the range; the specific diameter of the glass beads 3 is set according to actual needs, and can be set at any value within the range; the thickness of the surface layer 1 is 40-60 μm, and the specific thickness can be set according to actual needs and can be any value within the range; the thickness of the pressure sensitive adhesive layer 5 is 40-60 μm, and the specific thickness can be set according to actual needs and can be any value within the range.

The manufacturing process of the utility model is as follows:

coating a glue layer 2 on the surface layer 1, heating the surface layer by using a high-temperature mode to plant the glass beads 3 in the glue layer 2, then coating a titanium white powder layer 4, specifically titanium dioxide resin, curing the resin by UV light, and then compounding a pressure-sensitive adhesive layer 5.
