[0070] The preparation method of the antibacterial and antiviral aluminum alloy of the present invention comprises the following steps:

[0071] (1) Anodizing the aluminum alloy, forming an anodized film with micropores on the surface of the aluminum alloy;

[0072] (2) Soak the aluminum alloy obtained by the anodic oxidation in step (1) in sol A, then take out the soaked aluminum alloy and heat it once to obtain the antibacterial and antiviral aluminum alloy crude product;

[0073] (3) soaking the antibacterial and antiviral aluminum alloy crude product described in step (2) in sol B, and then taking out the soaked aluminum alloy for secondary heating to obtain the antibacterial and antiviral aluminum alloy;

[0074] Wherein, the sol A includes butyl titanate, and the sol B includes ribavirin and acyclovir.

[0075] Typical but non-limiting examples of the invention are as follows:

Embodiment 1

[0077] This embodiment provides a method for preparing an antibacterial and antiviral aluminum alloy, the preparation method comprising the following steps:

[0078] (1) First carry out sandblasting, alkali cleaning and pickling to aluminum alloy successively as pretreatment, the particle diameter of the sand used for described sandblasting is 120 orders, and described alkali cleaning adopts the sodium hydroxide solution of 45g / L, at 55 Alkali washing at ℃ for 7 minutes, washing with water and then pickling, the pickling uses 130g / L nitric acid solution, pickling at 25℃ for 1.5min, washing with water and drying; then in 200g / L sulfuric acid solution Carry out anodic oxidation, adopt direct current, use described aluminum alloy as anode, use graphite as cathode, the current density of described direct current is 9A / dm 2 , the power supply voltage is 30V, after anodic oxidation treatment at 15°C for 30 minutes, an anodic oxidation film with micropores is formed on the surface of...

Abstract

The invention relates to an antibacterial and antiviral aluminum alloy and a preparation method thereof. The preparation method comprises the following steps: (1) anodizing the aluminum alloy to form an anodic oxidation film with micropores on the surface of the aluminum alloy; 2) soaking in sol A and heating once; (3) soaking in sol B and heating twice to obtain an antibacterial and antiviral aluminum alloy; wherein, said sol A includes butyl titanate, and said sol B includes Liba Virin and acyclovir. In the preparation method, the butyl titanate from sol A is mainly decomposed into nano-titanium dioxide by heating once, and the nano-titanium dioxide is attached to the micropores and the surface of the anodized film through two sol soaking and heating treatments. The antibacterial and antiviral components compounded with ribavirin and acyclovir enable the aluminum alloy to have good and durable antibacterial and antiviral properties; moreover, the preparation method is simple to operate and is conducive to large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of metal material surface treatment, in particular to an antibacterial and antiviral aluminum alloy and a preparation method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal material in industry. It is widely used in aviation, automobile, ship, machinery manufacturing and chemical industry, etc. It is also a type of non-ferrous metal material that people often come into contact with in daily life. With the rapid development of the industrial economy, the demand for aluminum alloys is also increasing. However, aluminum alloys are prone to breed bacteria in humid air and cause corrosion. The originally small pitting corrosion will spread to become Large areas of corrosion seriously affect the use and decorative effect of aluminum alloys. Therefore, the research and development of antibacterial aluminum alloys has become a research hotspot in recent years for new ...
