Description

Technical Field

[0001] The utility model relates to the technical field of reflective films, in particular to a more stable crystal color grid reflective film. Background Art

[0002] Reflective film is a retro-reflective film product commonly used in traffic signs, which brings convenience to people's night travel. Full prismatic luminous film is a relatively common micro-prismatic luminous film. After a number of microcrystalline cubes are connected and arranged, an air layer is formed at the bottom after sealing. The diffraction phenomenon of light is used to make the incident light form internal total reflection. Figure 3 ) has only one sealed edge between the closed cavities, and the sealed edge structure is not firm. After the membrane is squeezed multiple times, the sealed edge of the closed cavity is prone to cracking, causing the surrounding closed cavities to be interconnected, resulting in poor reflective effect of the crystal color grid and short service life. Summary of the invention

[0003] The utility model provides a more stable crystal color grid reflective film to solve the problems of the existing crystal color grid having a loose edge sealing structure, resulting in poor reflective effect and short service life.

[0004] The utility model adopts the following technical solutions:

[0005] A more stable crystal color grid reflective film comprises a light-transmitting layer, a prism layer and a reflective layer which are stacked in sequence, an air layer is formed between the prism layer and the reflective layer, the air layer is composed of a plurality of evenly arranged closed cavities, the closed cavities are regular hexagons, the peripheral edges of the closed cavities are thermoplastic-formed edge sealings, and gaps are left between adjacent closed cavities.

[0006] Furthermore, the light-transmitting layer is made of polyvinyl chloride material.

[0007] Furthermore, an adhesive layer is attached to the side of the reflective layer facing away from the air layer.

[0008] Furthermore, a release layer is adhered to the side of the adhesive layer facing away from the reflective layer.

[0009] Furthermore, the prism layer is formed by a plurality of micro-prisms tightly and fixedly connected.

[0010] Furthermore, the reflective layer is made of PET material.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: an air layer is formed between the prism layer and the reflective layer of the reflective film of the utility model, and the air layer is composed of a plurality of evenly arranged closed cavities, and the closed cavities are regular hexagons. Each closed cavity has its own edge sealing, so that the closed cavity is not easily connected with other closed cavities, and the edge sealing structure is more firm and stable, thereby ensuring the crystal color grid reflective effect of the reflective film and extending the life of the luminous film.

[0016] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0017] Reference Figure 1-Figure 3 A more stable crystal color grid reflective film includes a light-transmitting layer 1, a prism layer 2 and a reflective layer 4 stacked in sequence, an air layer 3 is formed between the prism layer 2 and the reflective layer 4, the air layer 3 is composed of a plurality of closed cavities 30 arranged evenly, the closed cavities 30 are regular hexagons, the peripheral edges of the closed cavities 30 are thermoplastic edge sealing, gaps 31 are left between adjacent closed cavities 30, and air is evenly distributed in the closed cavities 30 and the gaps 31. The luminous film area aligned with the gaps 31 can reflect light retroactively, making the crystal color grid more beautiful. The light-transmitting layer 1 is made of polyvinyl chloride material.

[0018] Reference Figure 1 The side of the reflective layer 4 facing away from the air layer 3 is adhered with an adhesive layer 5 , that is, the air layer 3 and the adhesive layer 5 are respectively on the upper side and the lower side of the reflective layer 4 .

[0019] Reference Figure 1 A release layer 6 is pasted on the side of the adhesive layer 5 facing away from the reflective layer 4, that is, the reflective layer 4 and the adhesive layer 5 are respectively on the upper side and the lower side of the release layer 6, and the release layer 6 is a release paper.

[0020] Continue to refer to Figure 1 The prism layer 2 is formed by a plurality of micro-prisms tightly fixedly connected. The reflective layer 4 is made of PET material.

The air layer 3 is composed of a plurality of evenly arranged closed cavities 30. The closed cavities 30 are regular hexagons. Each closed cavity 30 has its own edge sealing, so that the closed cavity 30 is not easily connected with other closed cavities 30. The edge sealing structure is more firm and stable, thereby ensuring the crystal color grid reflective effect of the reflective film and extending the life of the luminous film.
