Abstract

The invention belongs to the field of air cleaning, and especially relates to a novel filtering material for an air cleaning machine, and a preparation method and a use thereof. The filtering material comprises at least one melt-blown fabric filter layer subjected to surface electrostatic treatment, and an active carbon layer uniformly arranged on the at least one melt-blown fabric filter layer, and the outer side of the at least one melt-blown fabric filter layer is also provided with a polyester skeleton supporting layer. The novel filtering material is an one body formed by sequentially bonding the polyester skeleton supporting layer as a first layer, the melt-blown fabric filter layer as a second layer, the active carbon layer as a third layer, the melt-blown fabric filter layer as a fourth layer and the polyester skeleton supporting layer as a fifth layer, can realize efficient cleaning of solid pollutants and gas pollutants, and can greatly reduce the volume of the filter core of the air cleaning machine and improve the space utilization rate; and the melt-blown fabric filter layers are subjected to the surface electrostatic treatment, so the adsorption efficiency of pollutants is greatly improved under same conditions, and the air cleaning efficiency is improved.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to a novel filter material for an air purifier with high purification efficiency for solid pollutants and gas pollutants, a preparation method and an application. Background technique [0002] With the development of science and technology and social progress, the requirements for the environment are becoming more and more stringent, and with the increasing popularity of household cars, the number of fine suspended particles such as PM2.5 in the air is also increasing, which seriously threatens the health of the human body. On the other hand, due to the indoor environmental pollution caused by construction, decoration and furniture, it has become a big killer affecting people's health. According to the data provided by the China Indoor Environmental Monitoring Center, the number of excess deaths caused by indoor air pollution in my country can reach 111,000, the number of...
