Problems solved by technology

[0007] 3. Target poisoning is prone to occur in the process of magnetron sputtering black film coating. This is because excessive hydrocarbon gas is filled into the furnace cavity for coating pure black products, which causes the concentration of argon ions to drop and affects the sputtering effect.

Embodiment 1

[0040] Evaporation coating technology is used to coat the surface of the object with an antibacterial layer.

[0041] The coating technology is carried out in the existing activation reaction evaporation deposition device: the substrate is made of dry solid materials, such as metal materials, non-metal materials, fiber products, polymer materials, dry plant materials or leather materials, antibacterial Evaporation materials are selected from Ti, Zn, Ca, Si, Mg, Zr, Cd, As, Sb, Se, Ce, Re, Cu, Ag, Pb, Hg, Co, Ni, Al, Fe and their oxides, sulfides, One or more of nitrides and carbides are used in an amount of 0.01% to 100% of the weight of the entire film layer, and the reaction gas is O 2 , N 2 , NH 3 、CH 4 、C 2 h 6 or H 2 S.

Embodiment 2

[0043] The multi-arc plating technology is used to coat the surface of the object with an antibacterial layer.

[0044] The coating technology is carried out in the existing multi-arc ion coating machine: the substrate is made of dry solid materials, such as metal materials, non-metal materials, fiber products, polymer materials, dry plant materials or leather materials, antibacterial The target materials are Ti, Zn, Ca, Si, Mg, Zr, Cd, As, Sb, Se, Ce, Re, Cu, Ag, Pb, Hg, Co, Ni, Al, Fe and their oxides, sulfides, One or more of nitrides and carbides are used in an amount of 0.01% to 100% of the weight of the entire film layer, as shown in Figure 1 and Figure 2. At this time, microscopic air holes need to be drilled on the antibacterial target 3 1, and use the air pipe 2 to pass the reaction gas into the air hole 1. In the multi-arc coating furnace, a magnetron sputtering antibacterial target is also provided, and the antibacterial target 3 is a cylindrical target. As shown i...

Embodiment 3

[0046] The surface antibacterial products were prepared by magnetron sputtering coating technology.

[0047] The coating technology is carried out in the existing magnetron sputtering ion coating machine: the substrate is made of dry solid materials, such as metal materials, non-metal materials, fiber products, polymer materials, dry plant materials or leather materials , the antibacterial target materials are Ti, Zn, Ca, Si, Mg, Zr, Cd, As, Sb, Se, Ce, Re, Cu, Ag, Pb, Hg, Co, Ni, Al, Fe and their oxides, sulfur One or more of compounds, nitrides, and carbides are used in an amount of 0.01% to 100% of the weight of the entire film layer. At this time, it is necessary to arrange a ventilation line on the surface of the substrate. And the antibacterial target material 3 is a cylindrical target, and this cylindrical target shown in Figure 4 is that the cylindrical target is made up of an inner core 3-1 made of a copper tube and an outer jacket 3-2 made of an antibacterial materia...

Abstract

The invention discloses a making method of antibiotic product of surface through physical gas-phase sediment technique, which comprises the following steps: plating antibiotic target or evaporating material on the base surface to form antibiotic coater through physical gas-phase sediment technique; allocating the antibiotic target or evaporated material with one or more component of Ti, Zn, Ca, Si, Mg, Zr, Cd, As, Sb, Se, Ce, Re, Cu, Ag, Pb, Hg, Co, Ni, Al, Fe and their oxide, sulfate, nitride and carbonate; aerating O2, N2, NH3, CH4, C2H6 or H2S as reacting gas.

Description

technical field [0001] The invention relates to a method for preparing a surface antibacterial product, in particular to a method for manufacturing a surface antibacterial product by using physical vapor deposition technology. Background technique [0002] The antibacterial ability of antibacterial products is mainly reflected in the surface of antibacterial products. Traditional antibacterial products are made by directly mixing antibacterial materials into metal materials, polymer materials, glazed porcelain and other substrates. This method causes a lot of waste of antibacterial materials, and the manufacturing process is complicated and the processing cost is too high. Some new technologies that adopt physical vapor deposition technology to manufacture surface antibacterial products have appeared in the prior art, such as the Chinese patent application "a surface antibacterial, wear-resistant stainless steel product and its preparation method" (application number: 200410...
