Description

Technical Field

[0001] The utility model relates to the technical field of diffusing elements and long-focus elements, and specifically relates to a diffusion film with a flame retardant function. Background Technique

[0002] A diffusion film is a material with special optical properties and is commonly used in the backlights of LCD displays and other optical devices. Its main function is to spread light so that it emits more softly and evenly. The important indicators of the diffusion film include the total light transmittance and haze. The total light transmittance refers to how much of the initial light flux can be maintained after the light passes through the diffusion film, while haze is a parameter describing the degree of light scattering by the material. A higher haze means softer light.

[0003] However, the diffusion film does not have flame retardancy. In the field of display lighting, especially for some safety exit signs, it is required that the diffusion film not only has a light homogenizing effect but also a certain flame retardant effect, so that it is not easy to burn under harsh conditions such as the high temperature of a fire, thus playing a better indication effect. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a diffusion film with a flame retardant function, which has the function of enabling the diffusion film to have a good flame retardant effect, so that the diffusion film still has a good indication effect in a fire site, and further improves the practicability of the diffusion film.

[0007] To achieve the above object, the utility model provides the following technical solution: A diffusion film with a flame retardant function includes a substrate. A first diffusion layer is bonded to the upper side of the substrate, a second diffusion layer is bonded to the lower side of the substrate, and a transparent heat dissipation layer is provided on the upper side of the substrate;

[0008] The transparent heat dissipation layer can quickly conduct the heat generated by various lights reflected back by the multi-layer optical coating, avoiding the surface temperature of the film body from being too high;

[0009] A flame retardant layer is bonded to the upper side of the transparent heat dissipation layer. The flame retardant layer is a resin that can prevent or slow down the burning speed after technical treatment;

[0011] The anti-scratch protection layer can prevent damage caused by scratching during the use of the optical diffusion film to ensure the light diffusion effect of the optical diffusion film.

[0012] Preferably, the outer surface of the anti-glare layer is provided with a micro-structure arranged in a staggered manner. The micro-structure arranged in a staggered manner can eliminate glare at high angles, enhance the effective light in the center, and improve the diffusion effect.

[0013] Preferably, a soft light layer is bonded between the first diffusion layer and the transparent heat dissipation layer. The soft light layer is made of a material with good light transmittance, and further soft light is achieved by using the characteristics of the material itself or by adding colors, making the soft light effect better.

[0014] Preferably, an ultraviolet ray barrier layer is bonded between the anti-glare layer and the wear-resistant layer. The ultraviolet ray barrier layer can effectively absorb ultraviolet rays in the light, reduce the damage of ultraviolet rays to the optical diffusion film, and extend its service life.

[0019] (1) For the diffusion film with a flame retardant function, a transparent heat dissipation layer is provided on the upper side of the base material. The transparent heat dissipation layer can quickly conduct the heat generated by various lights reflected by the multi-layer optical coating, avoiding the surface temperature of the film body from being too high.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A flame retardant layer 5 is bonded to the upper side of the transparent heat dissipation layer 4. The flame retardant layer 5 is a resin that can prevent or slow down the burning speed after technical treatment. An anti-glare layer 6 is bonded to the upper side of the flame retardant layer 5. The outer surface of the anti-glare layer 6 is provided with microstructures arranged in an alternating pattern. The microstructures arranged in an alternating pattern can eliminate high-angle glare, enhance the central effective light, and improve the diffusion effect. A wear-resistant layer 8 is provided on the upper side of the anti-glare layer 6. A scratch-resistant protective layer 9 is bonded to the upper side of the wear-resistant layer 8. The scratch-resistant protective layer 9 can prevent the scratching of the optical diffusion film during use from causing damage to ensure the light diffusion effect of the optical diffusion film.

[0027] Furthermore, a soft light layer 3 is bonded between the first diffusion layer 2 and the transparent heat dissipation layer 4. The soft light layer 3 is made of a material with good light transmittance, and further soft light is achieved by utilizing the characteristics of the material itself or the added color, resulting in a better soft light effect. A UV blocking layer 7 is bonded between the anti-glare layer 6 and the wear-resistant layer 8. The UV blocking layer 7 can effectively absorb the ultraviolet rays in the light, reduce the damage of ultraviolet rays to the optical diffusion film, and extend its service life. An antistatic layer 11 is bonded to the lower side of the second diffusion layer 10. The antistatic layer 11 obtains a certain antistatic effect through the coated antistatic coating, so that external dirt and dust are not easily attached to the surface of the optical diffusion film body, improving the antistatic effect of the optical diffusion film. A lower protective layer 12 is bonded to the lower side of the antistatic layer 11.

[0028] Furthermore, during use, the first diffusion layer 2 and the second diffusion layer 10 can scatter light, thus distributing the light softly and evenly. The soft light layer 3 further softens the light by utilizing the characteristics of the material itself or the added color, resulting in a better soft light effect. The transparent heat dissipation layer 4 can quickly conduct the heat generated by various lights reflected by the multi-layer optical coating, avoiding the surface temperature of the film body from being too high. The presence of the flame retardant layer 5 further improves the flame retardancy of the diffusion film. The anti-glare layer 6 can eliminate high-angle glare through the microstructures arranged in a staggered manner on it, enhance the central effective light, and improve the diffusion effect. The UV blocking layer 7 can effectively absorb the ultraviolet rays in the light, reduce the damage of ultraviolet rays to the optical diffusion film, and extend its service life. The wear-resistant layer 8 improves the wear resistance of the diffusion film, thereby extending the service life of the diffusion film. The scratch-resistant protective layer 9 can prevent damage caused by scratching during the use of the optical diffusion film to ensure the light diffusion effect of the optical diffusion film. The characteristics of the antistatic layer 11 make it difficult for external dirt and dust to adhere to the surface of the optical diffusion film body, improving the antistatic effect of the optical diffusion film. The lower protective layer 12 also plays a protective role for the diffusion film. Due to the presence of the transparent heat dissipation layer 4 and the flame retardant layer 5, the diffusion film can have a good flame retardant effect, and further, the diffusion film still has a good indication effect in a fire site, thereby improving the practicality of the diffusion film.

[0029] Working principle: When in use, the first diffusion layer 2 and the second diffusion layer 10 can scatter light, so as to distribute the light softly and evenly. The soft light layer 3 further softens the light by using the characteristics of the material itself or the added color, making the soft light effect better. The transparent heat dissipation layer 4 can quickly conduct the heat generated by various lights reflected by the multi-layer optical coating, avoiding the surface temperature of the film body from being too high. The existence of the flame retardant layer 5 further improves the flame retardancy of the diffusion film. The anti-glare layer 6 can eliminate the glare at high angles through the microstructures arranged in a staggered manner on it, enhance the effective light in the center, and improve the diffusion effect. The ultraviolet ray barrier layer 7 can effectively absorb the ultraviolet rays in the light, reduce the damage of the ultraviolet rays to the optical diffusion film, and extend its service life. The wear-resistant layer 8 improves the wear resistance of the diffusion film, and thus improves the service life of the diffusion film. The scratch-resistant protective layer 9 can prevent the optical diffusion film from being scratched and damaged during use, so as to ensure the light diffusion effect of the optical diffusion film. The characteristics of the antistatic layer 11 make it difficult for external dirt and dust to adhere to the surface of the optical diffusion film body, improving the antistatic effect of the optical diffusion film. The lower protective layer 12 also plays a protective role for the diffusion film.
