Problems solved by technology

[0004] The purpose of the present invention is to overcome the existing 3D printing technology to realize the difficulty of printing nano-level raised structures on the surface of the substrate and the problem that the surface of the substrate cannot be super-hydrophobic, and to provide a method that can use 3D printing technology to form micron raised particles on the surface of the substrate. At the same time, it has a nano-level fluff structure, that is, a micro-nano hierarchical structure, which makes the surface of the substrate have a good super-hydrophobic effect

Abstract

The invention relates to the technical field of 3D printing, and discloses a method for quickly preparing a super-hydrophobic surface on a matrix based on 3D printing. The preparation method comprisesthe following steps of: (1) drawing a geometric lattice array surface through graphics software, thereby obtaining a two-dimensional geometric structural model map; (2) taking the matrix, cleaning liquid on the surface of the matrix by an aqueous solution of ethanol, naturally drying in air to obtain a clean dried matrix surface, and uniformly coating a layer of an adhesive base film on the surface of the matrix, and naturally drying in air; (3) filling a printing raw material into a printer, and guiding the two-dimensional geometric structural model map in the step (1) into a 3D printer; and(4) putting the matrix onto a printing platform, and spraying raw materials on the adhesive base film to form the two-dimensional geometric lattice array through a printing spray head on the 3D printing platform. The super-hydrophobic matrix surface has relatively good super-hydrophobic properties.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a super-hydrophobic substrate surface printed with micron-nano hierarchical structure based on 3D printing technology. Background technique [0002] The development of superhydrophobic surfaces has attracted widespread attention and great interest. Metal corrosion is a serious problem for the protection of engineered systems, both operational and economical, such as aircraft, automobiles, pipelines and ships. Due to the wide range of potential applications of superhydrophobic surfaces, we need to find a more practical, fast and convenient, low construction cost, and easy preparation. 3D is a kind of rapid prototyping technology. It is a technology that directly manufactures three-dimensional entities of almost arbitrary shapes by reading digital model files. It can use the inherent specific properties of the surface of 3D printing materials to print micron The level of surface topogr...
