Abstract

The invention provides a method for preparing a high-reflectance working mould of microprism reflecting films by utilizing ultrasonic electroforming, and relates to microprisms. The method comprises the following steps of preparing electroforming solution, namely adding hot water into an electroforming tank, then adding nickel sulfate hexahydrate and nickel chloride in sequence, adding hot water into a container, then adding boric acid, then boiling the mixture, then adding lauryl sodium sulfate, pouring the solution into the electroforming tank after lauryl sodium sulfate is dissolved, adding saccharin and 2-butyne-1,4-diol into the electroforming tank, then injecting water to fully fill the electroforming tank and regulating the pH value to be 4.2; putting an anode nickel sheet into an anode basket, connecting the anode nickel sheet to an anode and connecting a nickel master mould to a cathode to carry out electroforming, and carrying out cathode demoulding to obtain the high-reflectance working mould of the microprism reflecting films. The method has the advantages that the ultrasonic parameters can be conveniently regulated by utilizing an ultrasonic washing machine during production; the coefficient of retroreflection of the microsized working mould of the microprism reflecting films can be controlled by regulating the ultrasonic parameters and the electroforming solution formula.

Description

technical field [0001] The invention relates to a microprism, in particular to a method for preparing a high-reflection microprism reflective film working mold by ultrasonic electroforming. Background technique [0002] 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 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] Nickel is a common electroforming and electroplating material. It is widely used due to its good performance. Most of the research is on the formulation of plating solution, electroplating equipment, DC electroforming and coating appearance. There are few researches on ultrasonic electro...
