Abstract

The invention discloses a preparation method for a grating structure color functional surface based on injection shaping. A silicon mother mold with a grating structure is prepared by an ultra-violetlithography machine and an etching machine; electric conduction processing is conducted on the silicon mother mold, a gold film conductive layer is deposited on the surface of the silicon mother mold,the silicon mother mold is then placed in an electroforming liquid as a cathode and connected with a negative electrode of a pulse power source, a conductive nickel plate is taken as an anode and connected to a power source positive electrode, an electroforming technology is started, ultrasonic cleaning is conducted with absolute ethyl alcohol and distilled water, and a nickel mold core of whichthe surface has the grating structure is obtained after drying; and the nickel mold core is installed on an injection molding mold, and then the injection mold is installed to an injection molding machine for injection molding, so that the grating structure color functional surface is obtained. The method is short in forming cycle, and high in production efficiency and has potential in batched manufacture.

Description

technical field [0001] The invention belongs to the technical field of structural color technology, and relates to a method for preparing a grating structural color functional surface based on injection molding. Background technique [0002] There are fine micro-nano structures on the surface of some animals and plants in nature, which will produce brilliant and colorful colors when exposed to light, called structural colors. Structural color has vivid color, not easy to fade, and iridescent effect. More importantly, the surface of structural color products does not need spraying, surface decoration and other processes, and is environmentally friendly. It has great research value in the fields of color rendering, anti-counterfeiting and decoration. and broad application prospects. Learning from nature, scientists continue to use modern microstructure molding methods to prepare different bionic microstructures to achieve artificial reproduction of structural colors. At pres...
