Problems solved by technology

[0002] In cement, steel, petrochemical and other fields, it is necessary to filter dust or smoke during the production process. Due to the electrostatic effect caused by the collision and friction between dust particles, the dust removal effect is reduced, especially in the case of flammable and explosive dust. It is easy to cause the danger of explosion during electric sparks. Therefore, it is of great significance to design a high-performance antistatic filter material to eliminate the static electricity on the dust surface in time for the production of these industries.
The existing antistatic filter material has a complex structure and often has a multi-layer structure, which is not conducive to gas circulation, and the cost is high

Abstract

The invention provides a dust-removing antistatic filter material and a preparation method thereof. The dust-removing antistatic filter material comprises a base cloth layer and a wear-resistant layerand a dust receiving layer which are respectively arranged on two sides of the base cloth layer and is characterized in that the base cloth of the base cloth layer is woven by warps and wefts, the warps are woven by teflon fibers and glass fibers through twisting and strand combination, the wefts are woven by polyester fibers and metal conductive fibers through twisting and strand combination, the surface layer of the base cloth subjected to liquid soaking is sprayed with conductive metal powder, microwave solidification is performed, the wear-resistant layer is prepared by alkali-free glassfibers, the dust receiving layer is prepared by polyisophthaloyl metaphenylene diamine fibers, the dust receiving face of the dust receiving layer is provided with FMS needled felt through needling, and the back side of the dust receiving layer is subjected to mechanical raising. The dust-removing antistatic filter material is good in toughness and high temperature resistance, the filter materialformed by the base cloth, the wear-resistant layer and the dust receiving layer is evident in antistatic performance, the soaked bath cloth is subjected to microwave heat solidification, resin can beheated and solidified from inside to outside, uniform film forming on the surface of the fibers is achieved, and surface comprehensive performance is increased.
