Abstract

The invention discloses a preparation method of a micro-prism working mould with a subsequent continuous processing function, relating to micro-prism reflection films. The preparation method comprises the following steps: adding water into an electroforming tank, and adding nickel sulfate hexahydrate and nickel chloride in sequence; adding boric acid into hot water, boiling, adding lauryl sodium sulfate, dissolving, pouring into the electroforming tank, adding saccharin and 1,4-butynediol into the electroforming tank, filling up water in the electroforming tank, and adjusting the pH value to be 4.0-4.4 to obtain an electroforming liquid; continuously copying a metal master mould on a PVC material to obtain a sheet-like template with a micro-pyramid structure on one side, wherein each side length of the micro-pyramid of the sheet-like template is 100-200 microns; keeping the micro-pyramid structure on the inner side, defining a barrel by the sheet-like template, performing butt welding to obtain an annular template, and performing electroforming pre-treatment on the inner surface of the annular template; putting an anode nickel plate into an annular anode basket, and connecting to an anode; and putting the annular template into the electroforming tank, connecting to a cathode while ensuring that the cathode is concentric with the anode, electroforming, and performing cathodic de-moulding to obtain the micro-prism working mould.

Description

technical field [0001] The invention relates to a microprism type reflective film, in particular to a preparation method of a microprism working mold which can be used for subsequent continuous processing of reflective film. Background technique [0002] The existing microprism-type reflective film working mold is sheet-shaped, and the follow-up production requires continuous splicing of the reflective film to form a continuous product. This production process seriously restricts work efficiency, and the instability of the splicing process also greatly affects product quality. [0003] In addition, under the general mechanical stirring electroforming process conditions, electroforming nickel can only get a rough surface, and its retroreflective performance is not high. The micro-prism reflective film is composed of dozens of micron-scale pyramid arrays, which cannot be mechanically polished after processing. The reflective film requires the working mold to have a high coeff...
