Problems solved by technology

[0003] When using air filter paper to filter, bacteria are easy to adhere to the surface of the air filter paper or remain in the 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. It will cause secondary pollution. The existing glass fiber air filter paper has poor antibacterial and antibacterial effects, and it is difficult to stop the reproduction of bacteria during use, resulting in general air filtration

Abstract

The invention discloses an antibacterial glass fiber air filter paper, which is prepared from the following raw materials in parts by weight: 80 to 100 parts of alkali-free glass microfiber, 10 to 15parts of polytetrafluoroethylene, 15 to 20 parts of dimethyl sulfoxide, 3 to 5 parts of houttuynin, 2 to 3 parts of 4-isopropyl-2-hydroxy-cycloheptyl-2,4,6-triene-1-ketone, 2 to 3 parts of methyl n-nonyl acetaldehyde, 0.3 to 0.5 part of an antibacterial agent, and 3 to 5 parts of a binder. The invention also discloses a preparation method of the antibacterial glass fiber air filter paper. The filter paper prepared by the invention can effectively block various bacteria in the air under the coaction of various raw materials to achieve the antibacterial effect; the bacterium resistance and sterilization are carried out separately inside and outside the filter paper by different substances, thereby effectively improving the air filtering effect.

Description

technical field [0001] The invention relates to the technical field of air filtration and purification, in particular to an antibacterial glass fiber air filter paper and a preparation 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. Glass fiber air filter paper is a key component of the air filter element, its thickness, weight, efficiency, resistance, strength, stiffness and other properties determine the performance of the air filter. The filter element is made of glass fiber air filter paper folded into a filter element by a folding machine and fixed with hot melt adhesive to form, and ...
