Abstract

The invention discloses a preparation method of an antistatic filter material, and belongs to the technical field of filter materials. The preparation method comprises the following steps: depositing a first conductive layer on a base cloth layer; loading second conductive layers on the surfaces of fiber layers by using an electrostatic spinning process; placing the treated base cloth layer between the two fiber layers, and fixedly binding the base cloth layer and the fiber layers together through needling or spunlacing. The filter material prepared by the preparation method is high in filter efficiency, antistatic property and high-temperature resistance.

Description

technical field [0001] The invention relates to a filter material, in particular to a preparation method of an antistatic filter material. Background technique [0002] In recent years, the problem of air pollution in my country has become increasingly prominent, especially in key industries such as thermal power, steel, and cement, where the emissions of air pollutants remain high. Therefore, industrial dust control has become a top priority. At present, the use of chemical fiber filter material to filter is the main method to control high-temperature dust, but in the process of use, a large amount of static electricity is generated due to friction between the discharged dust and the dust, and between the dust and the filter material. Due to the poor conductivity of the chemical fiber filter material, the accumulated charge cannot be eliminated or exported quickly, which is easy to cause fire or explosion. [0003] At present, the main method of preparing antistatic filter...
