Process for making bacteriostatic backing material with silver film

Abstract

The invention discloses a preparing method of bacteriostatic base material with silver film, which comprises the following steps: preparing vacuum cavity within one spraying target source; placing silver target material on the spraying target source; putting base material; loading base material in the vacuum cavity; filling one gas to form electrical paste in the vacuum cavity; charging preset power current to splash silver atom; depositing on the one surface of base material to form nanometer silver film.

Description

Technical field [0001] The invention relates to a manufacturing method, in particular to a manufacturing method that uses sputtering equipment used in high-tech industries to mass-produce nano-level silver films and can be applied to various substrates to form antibacterial effects. Background technique [0002] Vacuum sputtering is used in the semiconductor, optoelectronic, display and other industries. Its basic function is to sputter the films required in the semiconductor industry, such as metal and non-metallic metal oxides and nitrides. The thickness of the sputtering application is medium. Between 5,000 Ȧ~10,000 Ȧ (1.0 μm), it is used as a conductive or insulating layer of semiconductor materials. There is currently no technology to apply this high-tech equipment to the production and manufacturing of nanosilver antibacterial films. The so-called nanosilver is the nanoization of the "silver" in precious metals, and then it is used in various consumer products, because the ...

Problems solved by technology

[0003] However, the current nanotechnology focuses on the research and development of how to manufacture nano particles, and then attach them to the application products in other ways. The manufacturing cost of nano silver itself is extremely expensive. Dilute nano silver particles in a solvent, and then spray them on substrates such as cloth, filter screens, etc., and then dry them, or impregnate the substrate in a solution with nano silver particles, even very fine The silver wire is woven on the cloth. The cost of this method is very high, and the density of the coated nano-silver after solvent dilution is not high, and the antibacterial function will also be affected. The effect is not ideal and cannot be achieved. Due to the requirements of commercialization functions, and due to problems such as batch production capacity and product cost, the speed of commercialization is slow, and the market cannot be widely used and used. It is a pity that human beings still cannot enjoy the antibacterial quality of life brought by nano silver.
