[0002] As a material applied to the surface of electronic products, light-shielding electronic film plays an increasingly important role in notebooks, cameras, circuit boards and other products. However, existing light-shielding electronic film designs often have some problems;

[0003] Existing light-shielding electronic films usually only cover a single surface layer on the base material. Although this single-layer design can achieve a light-shielding effect to a certain extent, due to its relatively simple structure, it often leads to unstable light-shielding performance. In practical applications, this instability may cause problems such as light transmission and reflection, affecting the user experience;

[0004] Specifically, a single-layer light-shielding electronic film may face the following problems:

[0005] Uneven shading effect: Due to the influence of factors such as the uniformity and thickness of the surface material, the shading effect may vary between different areas, so that light can still be transmitted in some areas;

[0006] Poor weather resistance: Single-layer structures are often sensitive to external environmental factors (such as temperature, humidity, ultraviolet rays, etc.), and performance may degrade after long-term use;

[0007] Lack of adaptability: For electronic products that need to be covered on curved or irregular surfaces, a single-layer light-shielding electronic film is often difficult to adapt and is prone to wrinkling, falling off, etc. Summary of the invention

[0008] The utility model provides a light-shielding film with good light-shielding effect, aiming to solve the problem that the existing light-shielding electronic film with a single-layer design has deficiencies in light-shielding performance, weather resistance and adaptability.

[0009] The utility model is implemented as follows: a shading film with good shading effect comprises a base layer; a first shading unit and a second shading unit arranged on both sides of the base layer; wherein the first shading unit comprises: a first black ink layer arranged on the outer surface of the base layer; a reflective layer arranged on the outside of the first black ink layer; a second black ink layer arranged on the outside of the reflective layer; an antistatic coating arranged on the outside of the second black ink layer; a third black ink layer arranged on the outside of the antistatic coating; a protective coating arranged on the outside of the third black ink layer; the base layer and the first black ink layer, the reflective layer, the second black ink layer, the antistatic coating, the third black ink layer and the protective coating are connected by glue coating.

[0010] Preferably, the second shading unit comprises: a flexible layer arranged on the other side of the base layer; a fourth black ink layer arranged outside the flexible layer; and the base layer, the flexible layer and the fourth black ink layer are connected by glue coating.

[0011] Preferably, the thickness of the first shading unit is 35-50 um, and the thickness of the second shading unit is 15-25 um.

[0012] Preferably, the black ink concentration of the first black ink layer is greater than that of the second black ink layer, and the black ink concentration of the second black ink layer is greater than that of the third black ink layer.

[0013] Preferably, a first release paper is provided on the outer surface of the protective coating, and the first release paper matches the size of the protective coating.

[0014] Preferably, a second release paper is provided on the outer surface of the fourth black ink layer, and the second release paper matches the size of the fourth black ink layer. Compared with the prior art, the embodiment of the present application has the following beneficial effects:

[0015] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0016] First: This device has excellent shading performance. Its shading film cleverly integrates a multi-layer structure, including a base layer, a black ink layer, a reflective layer, and a protective coating, to achieve efficient shading. These layers work together to significantly reduce light transmission through absorption, reflection, and protection mechanisms, providing excellent shading effects. This carefully designed multi-layer structure not only enhances the shading performance of the shading film, but also significantly improves its weather resistance, stability, and service life, bringing users a long-lasting and reliable shading experience.

DETAILED DESCRIPTION

[0023] The following will be combined with the attached Figure 1 The present invention is described in detail with reference to the figures, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The utility model embodiment provides a shading film with good shading effect, such as Figure 1-4 As shown, it includes a base layer 1; a first shading unit 2 and a second shading unit 3 arranged on both sides of the base layer 1; wherein the first shading unit 2 includes: a first black ink layer 4 arranged on the outer surface of the base layer 1; a reflective layer 5 arranged on the outside of the first black ink layer 4; a second black ink layer 6 arranged on the outside of the reflective layer 5; an antistatic coating 7 arranged on the outside of the second black ink layer 6; a third black ink layer 8 arranged on the outside of the antistatic coating 7; a protective coating 9 arranged on the outside of the third black ink layer 8; the base layer 1 and the first black ink layer 4, the reflective layer 5, the second black ink layer 6, the antistatic coating 7, the third black ink layer 8 and the protective coating 9 are connected by glue coating.

[0025] It should be noted that since the existing single-layer light-shielding electronic film has deficiencies in light-shielding performance, weather resistance and adaptability, this solution achieves an efficient light-shielding effect by combining a multi-layer structure, including a base layer 1, a black ink layer, a reflective layer 5 and a protective coating 9. At the same time, by introducing a flexible layer 11, the light-shielding film not only maintains excellent light-shielding performance, but also has excellent flexibility and crease resistance, and can easily adapt to various curves and shapes, thereby greatly expanding its scope of application.

[0026] Specifically, in this embodiment, the scheme mainly includes a base layer 1; a first shading unit 2 and a second shading unit 3 arranged on both sides of the base layer 1; the base layer 1 serves as the basic structure of the shading film and provides support and stability for the film; the base layer 1 is usually made of a material with certain strength and weather resistance, such as polyester or polyvinyl chloride; the first black ink layer 4 is arranged on the outer surface of the base layer 1, and its function is to absorb the light passing through the base layer 1 and reduce the direct transmission of light; the black ink layer can effectively absorb light through its high concentration of melanin and reduce the transmittance of light; the reflective layer 5 is located on the outside of the first black ink layer 4, and is usually made of materials such as metal or metal oxide; the function of this layer is to reflect the light that has not been absorbed by the first black ink layer 4, and redirect the light to other directions through the reflection mechanism, so as to further reduce the transmission of light and improve Light-shielding effect; the second black ink layer 6 is located on the outside of the reflective layer 5, which further enhances the light-shielding effect; it further reduces the transmittance of light by absorbing and reducing the transmitted light, thereby improving the light-shielding performance of the light-shielding film; the antistatic coating 7 has excellent electrical conductivity and can effectively conduct the generated electrostatic charge to the ground or other conductors, thereby avoiding static electricity accumulation; as the outermost third black ink layer 8, it further enhances the overall light-shielding effect of the light-shielding film; the third black ink layer 8 absorbs and reduces the transmitted light, so that the light-shielding film has better light-shielding performance under the joint action of the multi-layer structure, and the protective coating 9 is located on the outside of the third black ink layer 8, mainly playing a protective role; it can prevent the black ink layer from being eroded and damaged by the external environment, such as moisture, oxygen, ultraviolet rays, etc., thereby maintaining long-term light-shielding performance;

[0027] Gluing is used to bond the various layers of structure together to ensure the integrity and stability of the shading film; the glue uses its adhesive force to tightly bind the various layers together to form an integral structure, thereby improving the mechanical strength and durability of the shading film; in summary, the shading film achieves an efficient shading effect through the support and stability of the base layer 1, combined with the absorption, reflection and protection mechanism of the multi-layer structure; this multi-level design not only improves the shading performance, but also enhances the weather resistance, stability and service life of the shading film.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the second shading unit 3 includes: a flexible layer 11 arranged on the other side of the base layer 1; a fourth black ink layer 12 arranged on the outside of the flexible layer 11; the base layer 1, the flexible layer 11 and the fourth black ink layer 12 are connected by glue coating.

[0029] In this embodiment, the flexible layer 11 is arranged on the other side of the base layer 1, and its main function is to provide a certain flexibility and crease resistance. The fourth black ink layer 12 is located on the outside of the flexible layer 11, and its main function is to further absorb and reduce the transmitted light. Through the combination of the flexible layer 11 and the fourth black ink layer 12, the light-shielding film is provided with flexibility and stronger light-shielding performance.

[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the thickness of the first shading unit 2 is 35-50 um, and the thickness of the second shading unit 3 is 15-25 um.

[0031] In this embodiment, the first shading unit 2 serves as the main structural layer of the shading film, and its thickness is relatively large. While shading, it is also for providing sufficient support and stability. The second shading unit 3 is relatively thin, which helps to improve the flexibility and adaptability of the shading film, so that it can better adapt to different curves and shapes.

[0032] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the black ink concentration of the first black ink layer 4 is greater than the black ink concentration of the second black ink layer 6 , and the black ink concentration of the second black ink layer 6 is greater than the black ink concentration of the third black ink layer 8 .

[0033] In this embodiment, the first black ink layer 4 has the strongest light absorption ability, which makes it a key layer in the light-shielding film, responsible for absorbing most of the transmitted light, thereby providing the main light-shielding effect. The second black ink layer 6 may be used to further enhance the light-shielding effect, or serve as a transition layer to help adjust the propagation of light between different layers. The third black ink layer 8 is mainly used to fine-tune the light-shielding effect or serve as the surface layer of the light-shielding film.

[0034] In a further preferred embodiment of the present invention, Figure 4 As shown, the outer surface of the protective coating 9 is provided with a first release paper 13 , and the size of the first release paper 13 matches that of the protective coating 9 .

[0035] In this embodiment, the first release paper 13 mainly functions to protect the protective coating 9 and prevent it from being contaminated, scratched or otherwise damaged during subsequent processing or use.

[0036] In a further preferred embodiment of the present invention, Figure 4 As shown, a second release paper 10 is disposed on the outer surface of the fourth black ink layer 12 , and the size of the second release paper 10 matches that of the fourth black ink layer 12 .

[0037] In this embodiment, the second release paper 10 mainly functions to protect the fourth black ink layer 12 and prevent it from being contaminated, scratched or otherwise damaged during subsequent processing or use.

[0038] Working principle: The base layer 1 is the foundation of the shading film, providing support and stability for the entire film; the first black ink layer 4 is located on the outer surface of the base layer 1, and its main function is to absorb light and reduce its direct transmission; through the high concentration of melanin, this layer can effectively reduce the light transmittance; the reflective layer 5 is located on the outside of the first black ink layer 4, and is made of metal or metal oxide; its main function is to reflect the light that has not been absorbed, thereby reducing the light transmission and improving the shading effect; the second black ink layer 6 further enhances the shading effect, absorbs and reduces the transmitted light, and further reduces the light transmittance; the antistatic coating 7 is located on the outside of the second black ink layer 6, and has excellent conductive properties, which can effectively conduct the generated electrostatic charge to the ground or other conductors, thereby avoiding static electricity accumulation, and the protective coating 9 is located on the outside of the third black ink layer 8, and mainly plays a protective role to prevent the black ink layer from being eroded by the external environment such as moisture, oxygen, and ultraviolet rays, thereby maintaining long-term shading performance;

[0039] The third black ink layer 8, as the outermost layer, further enhances the overall light-shielding effect of the light-shielding film, so that the film has better light-shielding performance under the joint effect of the multi-layer structure;

[0040] The glue coating bonds the various layers together to ensure the integrity and stability of the light-shielding film and improve its mechanical strength and durability; the flexible layer 11 is arranged on the other side of the base layer 1 to provide flexibility and crease resistance; the fourth black ink layer 12 is located outside the flexible layer 11 to further enhance the light-shielding performance; the first light-shielding unit 2 provides support and stability, while the second light-shielding unit 3 increases flexibility, so that the light-shielding film can adapt to different curved surfaces and shapes;

[0041] In the multi-layer structure, the first black ink layer 4 has the strongest light absorption ability and is the key to the shading effect; the second black ink layer 6 and the third black ink layer 8 may be used to further enhance the shading effect or adjust the light propagation; the first release paper 13 and the second release paper 10 respectively protect the protective coating 9 and the fourth black ink layer 12 to prevent damage during subsequent processing or use; in summary, the shading film achieves an efficient shading effect through the combination of a multi-layer structure and various functional layers, while ensuring weather resistance, stability and service life.
