Abstract

The invention discloses a micro-injection molding mould with a super-hydrophobic surface of a micro-nano composite structure and a micro-injection molding method. The mould comprises a fixed template. A movable template which can move up and down is arranged below the fixed template, an injection molding cavity is formed between the fixed template and the movable template, and a mould core is mounted in the injection molding cavity; the mould cover comprises a stainless steel made micro punched-plate and a nano aluminum alloy plate. And a micro-structure surface of the micro punched-plate and a nano structure surface of the nano aluminum alloy plate are laminated and overlaid. The mould disclosed by the invention is simple and practical. The prepared super-hydrophobic surface is good in hydrophobic property, surface treatment steps in a later period are reduced, and the problem that in the prior art, the processing difficulty of the super-hydrophobic surface is great, the mould core is poor in tolerance and the prepared super-hydrophobic surface is poor in hydrophobic property.

Description

technical field [0001] The invention belongs to the technical field of molding and preparation of functional surfaces, and relates to the manufacture of micro-nano structure surfaces, in particular to a micro-injection molding mold with a super-hydrophobic surface of a micro-nano composite structure and a micro-injection molding method thereof. Background technique [0002] With the continuous maturity of micro-nano molding technology and the continuous improvement of detection methods, super-hydrophobic surfaces with special functions have become one of the current hot research fields. Inspired by natural super-hydrophobic surfaces, researchers have prepared many artificial super-hydrophobic surfaces from various methods and methods, and gradually applied them in various fields of human life and production. At present, artificially prepared super-hydrophobic surfaces have excellent properties in self-cleaning, waterproof, anti-fouling, anti-corrosion, anti-snow, anti-adhesi...
