Problems solved by technology

However, there are also some shortcomings. Since the above two filter materials are not used for air outlets, the requirements for wind resistance are not high, so their wind resistance is relatively high, and they are not suitable for air outlet filters.
On the other hand, during the preparation of electretized non-woven fabrics, the adsorption efficiency of non-woven fabrics after PTFE emulsion impregnation is low, making PTFE emulsions unable to be permanently and firmly adsorbed by non-woven fabrics, thus affecting the electrostatic adsorption effect. Especially after a long time, the electrostatic adsorption force decays seriously
In addition, the above-mentioned non-woven fabrics also lack antibacterial function

Abstract

The invention relates to the field of air purification, and discloses a vehicle-mounted air purifying sheet and a preparation method thereof. The vehicle-mounted air purifying sheet is prepared by compounding an electrostatic adsorption layer and an antibacterial layer, wherein the electrostatic adsorption layer is an air inlet face; the electrostatic adsorption layer is a polypropylene non-woven fabric containing a nanometer electret; the antibacterial layer is a polypropylene non-woven fabric compounded with antibacterial substances. The vehicle-mounted air purifying sheet has a large loading capacity and high fastness for an electrostatic adsorption agent, has a good electrostatic adsorption effect on particles such as PM2.5, pollen, dust, soot and dust mites, and has high air permeability and small wind resistance; moreover, the vehicle-mounted air purifying sheet has antibacterial and noise reduction functions.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a vehicle-mounted air purification sheet and a preparation method thereof. Background technique [0002] In recent years, the urban environment has been seriously polluted, especially air pollution. According to the survey data of relevant departments, the main source of urban air PM2.5 pollution is vehicle exhaust pollution. Therefore, for drivers and passengers in vehicles running on the road, the threat of air pollution is more serious due to being on the road where the pollution sources are most concentrated. The fresh air system and air conditioning system of the vehicle will exchange the air inside the vehicle with the air outside the vehicle. Although these systems of the vehicle also have filtering devices, the filtering efficiency is not ideal. Therefore it is necessary to purify the air at the air outlet in the vehicle again. [0003] Generally, the requirements for t...
