Abstract

The invention discloses a device and a method for making a high-reflectance microprism working mold and relates to a microprism. An electroforming groove, an anode, a cathode, a bracket device and an ultrasonic system are arranged on the device, wherein a frame body, an anode, a cathode and a flange fixing rod are arranged on the bracket device; the anode, the cathode and the flange fixing rod are fixedly connected to the top of the frame body; a tool head, a flange, an amplitude-change pole and an ultrasonic power supply are arranged on the ultrasonic system; the front end of the tool head is arranged on the outer side of the cathode; the back end of the tool head is connected with the front end of the amplitude-change pole by virtue of the flange; the back end of the amplitude-change pole is connected with the ultrasonic power supply. The method comprises the following steps: adding water into the electroforming groove, and adding nickel sulfate hexahydrate and nickel chloride in sequence; adding boric acid into hot water, boiling, adding dodecyl sodium sulfate, dissolving, pouring into the electroforming groove, adding saccharin and 1,4-butynediol into the electroforming groove, and filling the electroforming groove with water to obtain an electroforming liquid; putting the anode into an anode basket, connecting a positive pole, connecting a nickel master mold with the cathode, and connecting the upper end of the cathode with the foremost end of the tool head; electroforming, and demolding to obtain the working mold.

Description

technical field [0001] The invention relates to a microprism, in particular to a preparation device and a preparation method of a high-reflection microprism working mold using cathode ultrasonic-pulse electroforming. Background technique [0002] Under the conditions of general mechanical stirring and DC electroforming process, electroformed nickel can only get a rough surface, and its retroreflective performance is not high. The micro-prism reflective film is made 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 coefficient of retroreflection, that is, high reflectivity must be obtained after electroforming. [0003] Stirring during electroforming includes mechanical stirring and ultrasonic stirring. Existing ultrasonic electroforming includes direct ultrasonic and indirect ultrasonic methods: direct ultrasonic refers to inserting the ultrasonic tool head directly...
