Embodiment 1

[0020] Step 1. Use 3D printing to prepare the PLA material into a P-curved spatial structure with a certain thickness, in which the period parameter is 2 and the surface thickness is 1mm, such as image 3 shown.

[0021] Step 2. Mix the refractory material and the binder in a certain proportion to prepare the coating slurry. The specific composition is: Al 2 o 3 , CaO and SiO 2 , the main components of the binder are water glass and silicon solution. Among them, the mass ratio of refractory material, water glass and silica sol is 85:10:5, and the main component of refractory material is Al 2 o 3 , and a small amount of CaO and SiO 2 , whose mass content is Al 2 o 3 : 95%, SiO 2 : 2%, CaO: 3%, add water and stir to adjust the Baume degree so that the Baume degree is 40.

[0022] Step 3. Use the P curved surface space structure obtained in step 1 and the coating slurry obtained in step 2 to prepare the shell, that is, first dip the P curved surface space structure with ...

[0027] Step 1. Use 3D printing to prepare the PLA material into a P-curved spatial structure with a certain thickness, in which the period parameter is 3 and the thickness of the curved surface is 1mm, such as image 3 Shown (instance two and instance one have the same spatial structure, the difference is that the surface thickness is different).

[0028] Step 2. Mix the refractory material and the binder in a certain proportion to prepare the coating slurry. The specific composition is: Al 2 o 3 , CaO and SiO 2 , the main components of the binder are water glass and silicon solution. Among them, the mass ratio of refractory material, water glass and silica sol is 85:10:5, and the main component of refractory material is Al 2 o 3 , and a small amount of CaO and SiO 2 , whose mass content is Al 2 o 3 : 95%, SiO 2 : 2%, CaO: 3%, add water and stir to adjust the Baume degree so that the Baume degree is 40.

Abstract

The invention discloses a preparation method of foamed nickel based on a P-curved space structure, and belongs to the field of high-temperature structural material preparation. The preparation methodmainly comprises the following steps: 3D printing a P-curved space structure by using PLA material, preparing a coating slurry, and pouring the coating slurry. Regarding the foamed nickel material prepared according to the method, the porosity and structure of the to-be-prepared foamed nickel material can be directly controlled by controlling the parameters of the P-curved space spatial structure,so as to achieve suitable mechanical properties. The foamed nickel material having a P-curved space structure not only has the characteristics of high porosity, small specific gravity, large specificsurface area, high specific strength, good damping and shock absorption performance, excellent heat insulation and sound insulation performance which common foamed metal has, the foamed nickel material according to the method also has an adjustable porosity to meet the specific performance requirements, so that the prepared foamed nickel is more suitable for the needs of the various industrial productions.

Description

technical field [0001] The invention relates to a preparation method of foamed nickel. Specifically, it relates to a preparation method of nickel foam based on a P-curved surface space structure, and belongs to the field of high-temperature structural materials. Background technique [0002] Nickel foam is a new type of lightweight high-temperature structural functional material with a large number of interconnected pores distributed in the nickel metal matrix. Nickel foam not only has the characteristics of high porosity, small specific gravity and large specific surface area unique to foam materials, but also has the characteristics of good metal phase toughness and corrosion resistance. This special pore structure makes the metal foam have the characteristics of high specific strength, good damping and shock absorption performance, excellent heat insulation and sound insulation, and has excellent thermophysical properties, good acoustic and electromagnetic properties, so...
