Background
The reflective material with the microprism array structure is increasingly and widely applied to the fields of various road traffic safety facilities, signboards, passive safety protection devices of vehicles and the like due to the excellent retroreflection property. The microprism array structure is a structure composed of three planes perpendicular to each other, and can totally internally reflect incident light from a front surface, thereby greatly improving reflection efficiency of the incident light. The plane based on such a structure is not limited to a certain specific size or shape, nor is it limited to the optical axis direction of the prism unit, and such a structure is generally called "cube-corner", "triangular-corner" or "trihedron".
The molding method of the mold is basically classified into a grinding method and a continuous embossing method according to the application fields of the microprism type reflective material. The die obtained by the grinding method has smaller and thick specification, and the microprism has larger size and is only suitable for injection molding and replication, so that the produced reflective material can only be suitable for the fields of passive safety protection devices of vehicles, road profile indication marks and the like.
