Problems solved by technology

[0005] The above-mentioned antibacterial and bactericidal coatings are all obtained by anodic oxidation film, and the pores of the anodic oxidation film are filled with bactericidal particles, but the above process obviously has the following technical problems: the pores of the oxide film obtained by anodic oxidation are straight up and down. The pore diameter is usually 50-150nm, and there are few pores higher than micron-scale anodized pores. It is extremely difficult to directly fill the bactericidal particles, and it cannot be completely filled, such as CN201210212975. The biggest technic...

Abstract

The invention provides an aluminum or aluminum alloy antibacterial material which is characterized in that aluminum or aluminum alloy is used as a base material, a metal middle layer is arranged on the surface of the base material, spherical storage spaces are uniformly distributed on the metal middle layer, and organic silicon silver-containing compounds are arranged in the spherical storage spaces and on the metal middle layer. The storage spaces can effectively control the release speed of silver ions, and finally the long-acting sterilization aluminum material is obtained.

Description

Technical field [0001] The invention relates to an aluminum or aluminum alloy antibacterial material. The base material is aluminum or aluminum alloy, which is a metal nano-ion modified functional material. In particular, it relates to nanotube holes in which silver-containing organic silicon composite particles are deposited on the surface of the base material. middle. Background technique [0002] Aluminum and aluminum alloys are one of the most widely used materials among non-ferrous metals. Aluminum alloys have many excellent properties such as low density, easy processing, low thermal expansion coefficient, high thermal conductivity, high specific stiffness and specific strength. It has been widely used in daily production and life, as well as in aviation, automobiles, high-speed rail, engine pistons, optical instruments, missile inlaid structures and other fields. However, with the further development of industrial production, higher requirements have been placed on...
