Abstract

The invention relates to the technical field of antibiosis, and discloses a preparation method of an infrared antibacterial coating. The preparation method comprises the following steps that an infrared photoresponsive catalytic material is pretreated; the pretreated infrared photoresponsive catalytic material is added into a film-forming material according to a preset ratio of the infrared photoresponsive catalytic material to the film-forming material, and a mixed material is obtained through a stirring process; and the mixed material is loaded on the surface of a substrate through a loadingprocess to obtain the infrared antibacterial coating. The infrared antibacterial coating obtained by the preparation method has good antibacterial performance, the photoresponse area of the materialis expanded, illumination can be more fully utilized, and the antibacterial performance is improved; and the process is simple and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of antibacterial technology, in particular to an infrared antibacterial coating and a preparation method. Background technique [0002] The spread and growth of microorganisms such as bacteria, mold, and viruses not only brings great pressure to the prevention and control of public health safety, but also causes problems such as deterioration, deterioration, corruption, and decomposition of items, resulting in economic losses and casualties. Therefore, antibacterial materials have attracted extensive attention and research. Traditional antibacterial methods include silver ion antibacterial, organic antibacterial and natural substance antibacterial. The above antibacterial technologies have instability, high cost, metal pollution, poor heat resistance, easy hydrolysis, and short validity period. , low bactericidal rate, and inability to use broad-spectrum and long-term effects. With the development of antibacterial te...
