Problems solved by technology

[0009] For silver-based antibacterial agents, although they have the advantages of high antibacterial activity and good safety, in sodium hydroxide or normal saline, due to the similar radius of sodium ions and silver ions, ion exchange is prone to occur, making the effect of silver ions invalid and affecting Its antibacterial durability; at the same time, the silver ions distributed on the surface of the ceramic membrane are less, and the antibacterial effect is relatively poor, so it is particularly urgent to prepare a ceramic membrane with high-efficiency and long-term antibacterial performance.

Embodiment 1

[0050] A preparation of a ceramic film with antibacterial function based on magnesium alloy, denoted as ZA0, the specific steps are:

[0051] Step 1, select a rectangular magnesium alloy plate with a length and width of 20mm and a thickness of 3mm, and then use silicon carbide water sandpaper to conform to 240 mesh, 480 mesh, 600 mesh, 800 mesh, 1000 mesh, 1200 mesh, 1500 mesh and 2000 mesh respectively. Sequentially, the surface of the magnesium alloy is ground and polished sequentially, and then cleaned with clean water, and placed at room temperature for 5 minutes to dry the surface, thereby obtaining a magnesium alloy with a smooth surface;

[0052] Step 2, first put the polished magnesium alloy plate into an isopropanol ultrasonic cleaner, take it out after cleaning for 3 minutes, and place it at room temperature for 5 minutes to make the surface dry; then perform plasma activation on the magnesium alloy plate, the specific activation process It is: put the magnesium allo...

Abstract

The invention relates to the field of surface treatment of magnesium alloy with an antibacterial function, and particularly discloses a preparation method of a ceramic membrane with an antibacterial function based on magnesium alloy. The method mainly comprises the following steps of, 1) grinding and polishing a magnesium alloy plate; 2) deoiling, cleaning and activating the surface of the magnesium alloy plate; (3) preparing a phosphate system electrolyte and carrying out micro-arc oxidation treatment on the magnesium alloy plate; and 4) performing hole sealing treatment on the magnesium alloy ceramic membrane. According to the method, an inorganic antibacterial agent and an organic antibacterial agent are compounded, so that the ceramic membrane has excellent antibacterial performance; and the method is simple to operate, safe and reliable, and has a wide application prospect in the fields of public places and electronic products.

Description

technical field [0001] The invention belongs to the field of magnesium alloy surface modification treatment, and in particular relates to a preparation method of a magnesium alloy-based ceramic film with antibacterial function. Background technique [0002] Today, with the continuous advancement of social science and technology and the improvement of people's living standards, people's awareness of health and environmental protection is constantly increasing, and people are paying more and more attention to the impact of surrounding environmental facilities on their own health; at the same time, due to the continuous deterioration of people's living environment, Due to global warming and other reasons, bacteria in the living environment breed, and the survival rate of bacteria is getting higher and higher, which makes people more and more at risk of infectious diseases, and the incidence rate is also showing an upward trend year by year. [0003] Bacteria, fungi and molds ar...
