Abstract

The invention relates to an antibacterial type PM2.5 (Particulate Matter2.5) filter material and application thereof. The antibacterial type PM2.5 filter material is mainly characterized by sequentially consisting of a windward layer, a primary filter layer, a sterilization layer, an active carbon filter layer and a fine filter layer, wherein the primary filter layer and the fine filter layer are nuclear pore films. The sterilization layer is provided with nano sliver particles; and the purpose of blocking PM 2.5 particles is effectively realized by utilizing the characteristics of uniform film hole diameter, uniform hole density and high porosity of the nuclear pore films and additionally arranging the sterilization layer through multi-layer filtration and adsorption effect; a filter element and a respirator, which are manufactured by the filter material, block the PM 2.5 particles more effectively in comparison with a conventional respirator, are long in service live, are good in gas permeability, meet characteristics of environmental-friendly requirements, and are worthy of being produced and popularized.

Description

Technical field [0001] The invention relates to the field of air filtration, in particular to a preparation method and application of materials for PM2.5 protection and anti-smog. Background technique [0002] In recent years, with the continuous heavy haze weather in many provinces and cities in my country, and the country's increasing emphasis on environmental protection, the newly revised "Ambient Air Quality Standard" has also added PM2.5 monitoring indicators. All these make people pay more and more attention to "PM2.5". [0003] PM, the English full name is particular matter, that is, particulate matter. PM2.5 refers to particulate matter with a diameter of less than or equal to 2.5μm in the atmosphere, also known as lung particulate matter. Its particle size is too small to be blocked by the respiratory tract. After being inhaled into the human body, it will directly enter the bronchi and alveoli, interfere with the gas exchange in the lungs, and cause other diseases. At ...
