Abstract

The invention provides a microprism-type reflective film. The microprism-type reflective film comprises a transparent basal film and a microprism layer. The microprism layer is arranged on a surface of the transparent basal film. The microprism layer is a combination of a plurality of microprism units. Each microprism unit comprises first prisms and a second prism. Each first prism is a triangular pyramid structure which is formed after cutting off one angle at a vertex angle and a base angle respectively and possesses a bottom surface, three side surfaces, three bottom cross sections and one top cross section. The second prism is a triangular pyramid structure and possesses a bottom surface, three side surfaces, one vertex angle and three base angles. A bottom surface of each first prism and a bottom surface of the second prism are combined with the transparent basal film. The second prism is arranged in a gap of the adjacent first prisms. By using the microprism-type reflective film, a viewing angle can be increased and demoulding difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of reflective films, in particular to a microprism-type reflective film and a manufacturing method thereof. Background technique [0002] Reflective materials with a microprism array structure are more and more widely used in various road traffic safety facilities, vehicle passive safety protection devices, signs and personal safety protection products due to their excellent retroreflective properties. [0003] The prism structure setting of the existing micro-prism type reflective film is unreasonable, and the effective incident angle and observation angle are small, which cannot meet the comprehensive reflective recognition requirements under different lighting conditions and different recognition distances in practical applications. In addition, the large-sized prism structure is difficult to release during production, and the performance requirements of the coating are high, resulting in the problem of h...
