Problems solved by technology

For example, adding a photocatalytic purification device to the sterilization measures of the air-conditioning system, but at the same time it brings some problems: such as ① the cost of the air-conditioning filter system increases;
The addition of chemical disinfectants in this product will cause corrosion of the air conditioning system, and the structure is complex and the production cost is high
[0005] When using air filter paper to filter, bacteria, viruses and microorganisms all adhere to the surface of the air filter paper. The suitable temperature and humidity of the filter paper provide a good environment for the reproduction of bacteria. Bacteria may multiply in large numbers. will cause secondary pollution

Abstract

The invention provides air filter paper which is effective in anti-bacterial performance and has a simple structure and a preparation method thereof. The anti-bacterial air filter paper comprises a filter paper substrate and an antibacterial agent covered on the surface of the filter paper substrate, and the mass of the antibacterial agent is 0.05 to 1 percent against that of the filter paper substrate. The filter paper substrate is preferably glass microfiber air filter paper, in particular air filter paper produced by glass microfibers, non-alkali continuous glass fiber chopped strands and organic fibers or plant fibers. The antibacterial agent is preferably a nano-silver ion antibacterial agent. As the improvement of the invention, adhesive can be used for the adhesion of the antibacterial agent and the filter paper substrate. The preparation method for the air filter paper has the following steps that: the surface of the filter paper substrate is sprayed with a diluent of the antibacterial agent and then is dried. The adhesive can also be sprayed after the diluent of the antibacterial agent is sprayed. The air filter paper has a simple structure, simple and convenient process, low cost, and high-efficiency sterilization and bacteria-inhibiting performances due to the fact that the antibacterial agent covers the surface of the air filter paper and partially permeates the air filter paper.

Description

technical field [0001] The invention relates to an air filter material and a manufacturing method thereof, more specifically, to an air filter paper with antibacterial function and a manufacturing method thereof. Background technique [0002] As the cleanliness requirements of pharmaceutical, medical and health, electronics and other industries are getting higher and higher, higher requirements are put forward for air purification devices. Dust, bacteria, viruses and microorganisms floating in the air must be removed by appropriate means. Among many air purification technologies, air filters are the most widely used and mature. In recent years, American researchers have found in the process of indoor air quality research that if the microorganisms deposited on the air filter after a period of use (before the end-of-life period) are not disposed of in time, serious secondary pollution will occur. . [0003] At present, to prevent the air filter from being polluted, auxilia...
