Embodiment 1
[0041] A vehicle-mounted air purification sheet, which is composed of an electrostatic adsorption layer and an antibacterial layer, and the electrostatic adsorption layer is an air inlet surface; wherein, the electrostatic adsorption layer is polypropylene non-woven fabric containing nano-electret; the antibacterial layer Polypropylene non-woven fabric compounded with peptide silver. The air resistance of the antibacterial layer is smaller than that of the electrostatic adsorption layer.
[0042] The polypropylene non-woven fabric containing nano electret is made from the following raw materials in mass percentage: 75% polypropylene, 1% hydrophobic cyclodextrin, 5% modified coral powder, 1.5% nano sepiolite, silane 0.5% coupling agent, 17% polytetrafluoroethylene.
[0043] The preparation method of the modified coral powder is as follows: the coral is washed and roughly ground to 80 mesh, then placed in a muffle furnace and heated to 350°C under anaerobic conditions, calcined...
