specific Embodiment approach 1

[0031] Specific Embodiment 1: In this embodiment, a method for preparing an ultra-light biomimetic metal material is specifically carried out according to the following steps:

[0032] 1. Template preparation: 3D printing method is used to prepare photosensitive resin template with bionic structure;

[0033] 2. Template pretreatment: the photosensitive resin template prepared in step 1 is subjected to stress relief treatment, alkaline degreasing treatment, surface roughening treatment, sensitization treatment, activation treatment, reduction treatment, and weak corrosion treatment;

[0034] 3. One-time plating of the template: metal plating is carried out on the overall structure of the template after the pretreatment in step 2;

[0035] 4. Secondary plating of the template: deactivate the template processed in step 3, and apply metal plating to the outer surface of the template again;

[0036] 5. Removing the template: the template processed in step 4 is removed to obtain th...

specific Embodiment approach 2

[0037] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the stress relief treatment in Step 2 is: cleaning the template with acetone for 30-40 minutes. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0038] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the alkaline degreasing treatment in step two is: the concentration is 10g / L sodium hydroxide solution, 3g / L sodium silicate solution, 12g / L L trisodium phosphate solution and 8g / L sodium carbonate solution were mixed according to the volume ratio of 1:1:1:1 to prepare a mixed solution, and then the template was put into the mixed solution and ultrasonically cleaned for 15-30 minutes. Others are the same as in the first or second embodiment.

Abstract

A method for preparing an ultra-light biomimetic metal material, the invention relates to the technical field of biomimetic metal material preparation. The invention aims to solve the technical problems that the bionic metal material prepared by the existing method has high quality and is difficult to apply. Methods: 3D printing structural template; pretreatment of the template; metal plating on the overall structure of the template; deactivation treatment, metal plating on the outer surface of the template again; removal of the template. The ultra-light biomimetic metal material prepared by the method of the invention can greatly reduce the density of the material under the condition of ensuring the strength, and the interior of the biomimetic metal material structure can have various structures; the thickness of the biomimetic metal material can be controlled by gradient change. The production process is simple, easy to implement, low in preparation cost and flexible in operation. The invention is used for preparing bionic materials.

Description

technical field [0001] The invention relates to the technical field of bionic metal material preparation. Background technique [0002] Biomimetic material is a new type of functional material. It is a designable intelligent material based on natural materials, artificial synthetic materials, and organic polymer materials. It refers to materials developed by imitating various characteristics or characteristics of organisms. Artificial materials designed and manufactured according to the operating mode of living systems and the structural laws of biological materials. Therefore, the biggest feature of biomimetic materials is designability. People can extract biological prototypes in nature, explore their functional principles, and design new functional materials with similar properties through this principle. [0003] Therefore, the research on bionic technology can be done through the following points: (1) Structural bionics: through the analysis and research of biological ...
