Efficient self-cleaning energy-storage illuminating light reflection film

Abstract

The invention discloses an efficient self-cleaning energy-storage illuminating light reflection film. The efficient self-cleaning energy-storage illuminating light reflection film sequentially comprises a self-cleaning cladding layer, a light reflection film layer, an air layer, an energy-storage illuminating light reflection film layer and an adhesive layer from top to bottom. According to the efficient self-cleaning energy-storage illuminating light reflection film, cleaning can be kept for a long time through the self-cleaning effect of the self-cleaning cladding layer outdoors; under the illumination condition, and the warning and guiding aims are achieved through the efficient light reflection effect of the light reflection layer; under the dark condition, the warning and guiding aims can be also achieved through the illuminating effect of the energy-storage illuminating layer. The light reflection film has the advantages of being good in self cleaning, efficient in light refection, high in illuminating brightness, long in illuminating time and service life, wide in application range and the like.

Description

technical field [0001] The invention relates to the technical field of luminescent reflective materials, in particular to a high-efficiency self-cleaning energy-storage luminescent reflective film. Background technique [0002] When the light hits the surface of the reflective film at night or in insufficient light, its bright reflective effect can effectively enhance people's recognition ability, so that people can see obstacles more clearly, thus playing a role of warning and guidance. function to avoid accidents. Therefore, it is widely used in the transportation industry and produces obvious social benefits. However, the traditional reflective film has the following disadvantages: (1) the effective incident angle is small, and the total internal reflection phenomenon disappears when the incident angle is too large; (2) the observation angle is small, and the retroreflection effect is poor; Symmetrical shape, the retroreflective brightness is different when viewed from ...

However, the traditional reflective film has the following disadvantages: (1) the effective incident angle is small, and the total internal reflection phenomenon disappears when the incident angle is too large; (2) the observation angle is small, and the retroreflection effect is poor; Symmetrical shape, the retroreflective brightness is different when viewed from different angles; (4) If there is no light at night, it cannot play the role of warning and guidance

However, simply superimposing or mixing the luminescent material and the reflective material will not only fail to obtain a good luminescent and reflective effect, but will cause the luminous and reflective to interfere with each other, and the effect is unsatisfactory.

[0004] The reflective film and luminous reflective film mentioned above are mostly used in outdoor environments. The actual application results show that the reflective film and luminous reflective film are easily polluted after a period of time, and their reflective and luminous effects will be significantly worse. Not only will it bring certain security risks, but its application range is also limited.
