Abstract

The invention relates to the field of air purification, and discloses air filtering non-woven fabric for an air inlet filter screen of an air conditioner, and a preparation method of the air filtering non-woven fabric. The air filtering non-woven fabric for the air inlet filter screen of the air conditioner is formed by alternately compounding electrostatic absorption layers and antibacterial layers; a single layer of the air filtering non-woven fabric for the air inlet filter screen of the air conditioner comprises two layers or four layers; the electrostatic absorption layers are air inlet faces; the electrostatic absorption layers are respectively made from polyethylene non-woven fabric containing a nano electret; the antibacterial layers are respectively made from polyethylene non-woven fabric compounded with antibacterial substances. The air filtering non-woven fabric provided by the invention not only is high in loading capacity of an electrostatic absorbent and high in fastness, good in electrostatic absorption effect for particulate matters (PMs) such as PM2.5, pollen, dust, smoke and dust mite, good in air permeability and low in wind resistance, but also has an antibacterial function.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air-filtering non-woven fabric for an air-conditioning air inlet filter and a preparation method thereof. Background technique [0002] There is usually an air inlet filter cloth at the air inlet of the air conditioner. On the one hand, the function of the air inlet filter cloth is to prevent particles and impurities in the air from entering the air conditioner and prolong the service life of the air conditioner; on the other hand, it can absorb particles in the air to purify the air. . Generally, the requirements for the filter cloth of the air inlet of the air conditioner are firstly that the filtering effect is good, and that it can block or absorb most particles; [0003] Air-conditioning air inlet filter cloths in the prior art are usually just ordinary non-woven fabrics. In order to ensure its air permeability and reduce wind resistance, it usually has a large porosity, ...
