[0003] The Chinese patent application number 2011100366527 discloses a car air-conditioning filter material and its preparation method. This material can filter out harmful microorganisms, dust and volatile organic compounds in the air, but the pore size of the filter cloth is generally 130 μm-150 μm. Larger pore size cannot effectively remove PM2.5 air particles
The Chinese patent with application number 2013103163684 discloses a vehicle-mounted air conditioner purifier that can remove PM2.5 particles. This purifier can filter PM2.5 particles, but this device needs to arrange filters in series in the direction of air flow. Significantly increases the resistance to air flow, takes up a lot of space and costs more

Abstract

The invention discloses an automotive filter for filtering PM2.5 air particles and a preparation method. The automotive filter is mainly used for filtering PM2.5 air particles in an automobile. A filtration material of the filter includes a base layer and an adsorption layer, wherein the base layer is made of a reticular fiber layer non-woven fabric base layer material formed by using a carding machine to comb short fibers, a reticular fiber layer is provided with an irregular surface, and the adsorption layer is formed by adopting an electrostatic spraying method to spray a diatomite adsorbent on an adhesive on the irregular surface of the base layer. The automotive filter can effectively adsorb PM2.5 particles entering the automobile through an air conditioning system and can also make air resistance not increase obviously. The electrostatic spraying method is adopted to spray diatomite on the surface of the base layer material and can make diatomite distribution uniform, and the thickness is controlled to ensure adsorption capacity under the condition of minimum resistance.

Description

technical field [0001] The invention relates to the technical field of air purification devices, in particular to an automotive filter capable of filtering PM2.5 particles in the air and a manufacturing method. Background technique [0002] In recent years, with the rapid development of the vehicle industry, people pay more and more attention to environmental protection issues. Especially in terms of air pollution, the research on the harm of PM2.5 particles in the air to human health has gradually deepened. The research shows that PM2.5 has small particle size, large area, strong activity, easy to be accompanied by toxic and harmful substances, and is less than 2.5μm Particles can be inhaled into the bronchioles and alveoli. After PM2.5 enters the human body to the alveoli, it directly affects lung function and makes the body prone to hypoxia. Moreover, once PM2.5 enters the alveoli, it is difficult to fall off when adsorbed on the alveoli, and this adsorption is irrevers...
