Porous antibiotic air filter paper and making method thereof

Abstract

The invention discloses a porous antibiotic air filter paper. The porous antibiotic air filter paper is made by using the following raw materials, by weight, 53-56 parts of a flax pulp, 43-45 parts of a softwood pulp, 0.2-0.3 parts of benzalkonium bromide, 0.3-0.5 parts of petroleum ether, 2-3 parts of soybean powder, 3-4 parts of nanometer porcelain clay, 1-2 parts of crushed horseradish, 2-3 parts of zircon, 1-2 parts of macro-porous silicon powder, 0.6-0.8 parts of calcium peroxide, 4-7 parts of chlorinated paraffin, 0.6-0.8 parts of turkey red oil, 0.3-0.4 parts of xanthan gum, 7-9 parts of a polyacrylate emulsion, 1-2 parts of an assistant and a proper amount of water. Horseradish in the above raw materials has a certain antibiosis effect; the addition of calcium peroxide realizes slow oxygen release after meeting water, and forms minimal holes on the filter paper layer, so the adsorption effect is increased; and the addition of the assistant is safe and environmentally friendly, and forms minimal holes on the surface of filter paper, so the adsorptivity is increased.

Description

technical field [0001] The invention relates to the field of automobile filters, in particular to a porous antibacterial air filter filter paper and a preparation method thereof. Background technique [0002] Automobile air filter paper is the core material for manufacturing automobile engine air filters. Since the air filter is located in the intake system of the engine, and the engine usually emits a lot of heat when it is working, it is generally hoped that this air filter medium has good performance. Excellent filtration performance and high filtration efficiency, as well as certain high temperature resistance, water resistance and burst resistance. The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency; and when using air filter paper to filter, bacteria, viruses and microorganisms all adhere to the surface of the air filter paper, and the suitable temperature and humidity of the filter paper will be It pr...

Problems solved by technology

The existing filter paper has poor adsorption and low filtration performance, which leads to low filtration efficiency; and when using air filter paper to filter, bacteria, viruses and microorganisms all adhere to the surface of the air filter paper, and the suitable temperature and humidity of the filter paper will be It provides a good environment for the reproduction of bacteria. Bacteria may multiply in large numbers. Once the bacteria multiply in large numbers, it will cause secondary pollution.
