Embodiment 1

[0031] figure 1 Respectively indicate that the light-energy antibacterial nanofiber composite material is used as a filter structure. The filter is composed of 1 inner layer of non-woven fabric layer, 2 middle antibacterial layer sprayed with high-efficiency organic amino acid zinc phthalocyanine photocatalyst, and 3 outer layer of nanofibers. Composed of thermal composite filter layers, it can effectively filter PM2.5 particles up to 95%, and at the same time, under the irradiation of natural light or LED red light, high-energy oxygen is generated, which is effective against common pathogenic bacteria (including but not limited to Staphylococcus aureus, Escherichia coli and white Candida) 15 minutes - 1 hour to achieve a kill rate of 70% - 99% (such as Figure 8 shown). figure 2 The schematic diagram of the three-dimensional structure of the filter, the structure of the filter can effectively fit the human face, and can be completely fitted with the mask.

Embodiment 2

[0033] Such as image 3 As shown, a light energy antibacterial material consists of 1 antibacterial layer and 2 LED red light sources. The antibacterial layer in this combination is mainly composed of bamboo fiber fabric sprayed with high-efficiency organic amino acid zinc phthalocyanine photocatalyst. The organic amino acid zinc phthalocyanine photocatalyst on the antibacterial layer generates free or singlet oxygen under light irradiation, which can Kill super bacteria, and achieve a killing rate of 70% -99% for common pathogens (including but not limited to Staphylococcus aureus, Escherichia coli and Candida albicans) in 15 minutes - 1 hour (such as Figure 8 As shown), it can well avoid the secondary pollution of bacteria. This kind of light energy antibacterial material is suitable for air purification products with existing filter systems.

Embodiment 3

[0035] Such as Figure 4 As shown, a light-energy antibacterial nanofiber composite material consists of 1 filter layer, 2 antibacterial layers, and 3 LED red light sources. The antibacterial layer in this combination is mainly composed of bamboo fiber fabric sprayed with high-efficiency organic amino acid phthalocyanine zinc photocatalyst. After thermal fusion technology, nanofibers with a unit weight of 0.03g are fused to bamboo fibers to form a nanofiber filter layer. . The organic amino acid zinc phthalocyanine photocatalyst on the antibacterial layer generates free or singlet oxygen under light irradiation, which can kill superbugs and is effective against common pathogenic bacteria (including but not limited to Staphylococcus aureus, Escherichia coli and Candida albicans ) 15 minutes - 1 hour to achieve a kill rate of 70% - 99% (such as Figure 8 Shown), can well avoid the secondary pollution of bacteria. At the same time, the filter material of this structure can fil...

Abstract

The invention provides an optical energy antibacterial nano fiber composite material and application of the material to air purification products. Particularly, the optical energy antibacterial nano fiber composite material comprises (1) an antibacterial layer which contains an efficient organic amino zinc phthalocyanine photocatalyst stimulated by laser, and (2) a filtering layer composed of nano fibers, wherein the two layers are fused by adopting a special hot fusion process to form the composite material. The antibacterial layer contains the organic amino zinc phthalocyanine photocatalyst stimulated by the laser, and high-energy-state oxygen is generated to kill microorganisms, pathogenic bacteria and drug resisting bacteria; and a net-shaped structure formed by the nano fibers of the filtering layer can be used for effectively filtering PM2.5 fine particles with the sizes being more than 0.3 micron. An air filtering element prepared from the composite material can be applied to the air purification products including mask filtering sheets, air purifiers, air conditioners and the like and is used for efficiently purifying air; the bacteria can be effectively killed and secondary pollution is avoided; and filtered dust accumulated in a use process is convenient to clean and the filtering element can be repeatedly utilized, so that the environmental friendliness and resource conservation are facilitated.

Description

technical field [0001] The invention relates to a light-energy antibacterial nanofiber composite material and its application in air purification products, belonging to the field of public environmental protection and sanitation. Background technique [0002] With the development of the economy, the air pollution caused by industrial production and urban life has become increasingly serious, and smog has become one of the major hazards to people's healthy breathing. The purpose of air purification products is to meet people's needs for clean air in living and working environments, and to serve people's healthy breathing. The core component of air purification products is the air filter element. The air filter element material with excellent performance needs to have two functions: 1) Effectively filter PM2.5 fine particles; 2) Effectively kill pathogenic bacteria, avoid bacterial growth, and cause secondary air pollution . [0003] The air purification filter elements curr...
