Embodiment 1

[0024] A copper film of 3 micrometers is deposited on the surface of the foam sponge material (about 550 micrometers in pore size) by ion sputtering coating method, so that the foam sponge material obtains electrical conductivity. Under the conditions of the composition ratio and process parameters shown in Table 1, electroplate copper film on the foam sponge material after conductive treatment. When the film thickness of the electroplating material is about 20 μm, take it out from the electroplating solution, wash it with water, and dry it in the air. , heated to 800°C for 3 hours under the protection of argon, and took it out after cooling down to room temperature, and removed the foam sponge in the grid frame to form a metal copper grid;

[0055] The difference from Example 1 is:

[0056] A 2-micron copper film is deposited on the surface of the foam sponge material (about 450 micrometers in pore size) by ion sputtering coating method, so that the foam sponge material obtains electrical conductivity. Under the conditions of composition ratio and process parameters shown in Table 1, electroplate copper film on the foam sponge material after conductive treatment. When the film thickness of the electroplating material is about 50 μm, take it out from the electroplating solution, wash it with water and dry it in the air. , heated to 850°C for 1 hour under the protection of argon, took it out after cooling down to room temperature, removed the foam sponge in the grid frame, and formed a metal copper mesh; finally, deposited 2.5 micron thick metal copper mesh on the surface of the prepared metal copper mesh Cu plus CeO 2 film, so that the supported metal (Cu+CeO 2 ) / Cu composite mesh antibacterial filter metal mater...

Embodiment 3

[0059] The difference from Example 1 is:

[0060] A 2.5-micron copper film is deposited on the surface of the foam sponge material (with a pore size of about 450 micrometers) by ion sputtering coating method, so that the foam sponge material obtains electrical conductivity. Under the conditions of the composition ratio and process parameters shown in Table 1, electroplate copper film on the foam sponge material after conductive treatment. When the film thickness of the electroplating material is about 23 μm, take it out from the electroplating solution, wash it with water, and dry it in the air. , heated to 700°C for 4 hours under the protection of argon, took it out after cooling down to room temperature, removed the foam sponge in the grid frame, and formed a metal copper grid; finally, deposited a 2-micron-thick metal copper grid on the surface of the prepared metal copper grid.

Abstract

The invention relates to the technology for preparing a filter screen material, in particular to a (Cu+CeO2) / Cu composite mesh antiseptic filtering metal material with good antiseptic performance, anda preparation method and application thereof to solve the problems of bacteria breeding, insufficient copper intake of a human body and the like; and the antiseptic filtering metal material can be applied to production and filter devices for gases or liquid such as foods, drinks, alcohols and the like and filter screens in air conditioners. The foam sponge taken as a substrate material is loadedwith metal (Cu+CeO2) / Cu to form the high-porosity mesh antiseptic filtering metal material. The preparation method comprises that: the substrate material after conductive treatment is plated with an antiseptic Cu coating; when the copper coating film reaches required thickness, the substrate material is subjected to heat treatment in a vacuum furnace or an argon protection furnace to form a metalcopper mesh; and finally, the surface of the metal copper mesh is plated with (Cu+CeO2) to prepare the metal (Cu+CeO2) / Cu loaded composite mesh antiseptic filtering metal material of which the porosity is between 85 and 96 percent, and the pore diameter can be adjusted in a range between 350 and 500 micrometers according to actual requirement.

Description

Technical field: [0001] The present invention relates to the preparation technology of filter net material, specifically a kind of (Cu+CeO 2 ) / Cu composite mesh antibacterial filter metal material and its preparation method and application, that is: copper mesh surface plating (Cu+CeO 2 ) composite mesh antibacterial filter metal material and its preparation method and application, which can be applied to gas or liquid production filter devices such as food, beverages and alcohol and filter screens in air conditioners. Background technique: [0002] The global theme of the 21st century is "health and the environment". Everyone's life and health, 60% are in their own hands. That is to say, apart from factors that cannot be changed such as genetics, the environment in which an individual lives plays an important role in life and health [Document 1: Jin Zongzhe, Inorganic Antibacterial Materials and Applications, Beijing: Chemical Industry Press, August 2004 ]. Sterilization...
