The plane based on this structure is not limited to a certain size or shape, nor is it limited to the direction of the optical axis of the prism unit. This structure is usually called "cube pyramid", "triangular pyramid" or "trihedron" , but the prism structure design of the existing micro-prism reflective film is unreasonable, and cannot meet the comprehensive reflective recognition requirements under different lighting conditions and different recognition distances in practical applications

The invention discloses a microprism reflecting film, and belongs to the technical field of reflecting films. The microprism reflecting film comprises a reflecting surface layer, a microprism layer, areflecting layer, an adhesive layer and release paper in sequence from top to bottom, wherein the microprism layer comprises a plurality of microprism units distributed in an array; each microprism unit comprises a reflecting outer ring and a reflecting cone located at the center of the reflecting outer ring; and the reflecting outer ring and the reflecting cone respectively comprise six first reflecting surfaces and six second reflecting surfaces. Compared with the traditional reflecting films, after light is irradiated to the microprism units, light sources at the peripheries of the microprism units are concentrated at the middle parts of the microprism units after twice reflection and then return along irradiation directions of the light sources, so that the reflecting brightness of single microprism units are improved, the display effect of the reflecting film is better, pattern air brushing can be carried out on the surfaces, the pattern color and display are more gorgeous and marked, and the reflecting film can be widely applied to the fields of outdoor advertisements, road traffic and the like.
Description
technical field [0001] The invention discloses a microprism reflective film and a preparation method thereof, belonging to the technical field of reflective films. Background technique [0002] Reflective materials with a microprism array structure are more and more widely used in various road traffic safety facilities, signs and vehicle passive safety protection devices due to their excellent retroreflective properties. The so-called microprism array structure refers to a structure composed of three mutually perpendicular planes, which can perform total internal reflection on the incident light from the front surface, thereby greatly improving the reflection efficiency of the incident light. The plane based on this structure is not limited to a certain size or shape, nor is it limited to the direction of the optical axis of the prism unit. This structure is usually called "cube pyramid", "triangular pyramid" or "trihedron" , but the prism structure design of the existing m...
