Abstract

The invention relates to a self-cleaning anti-static high-temperature-resistant filter bag fabric and a preparation method thereof. The preparation method comprises the following steps: preparing a titanium sol by taking titanium tetrachloride, isopropanol and the like as raw materials; spinning the sol, washing with water, oiling, and drying to obtain silk threads; drying the silk threads to obtain gel fibers, and sintering the gel fibers at a high temperature in a nitrogen atmosphere to obtain TiN ceramic fibers; preparing a TiN ceramic fiber fabric from the TiN ceramic fibers through unwinding, doubling twisting, warping, drafting and weaving; carrying out silver plating treatment on the surface of the TiN ceramic fiber fabric; and finally coating with a three-proofing finishing agent to prepare the self-cleaning anti-static high-temperature-resistant filter bag fabric. The filter bag fabric prepared by the preparation method disclosed by the invention shows a low reflection coefficient decline rate, so that the stain resistance is strong; and by coating the TiN ceramic fiber fabric with the three-proofing finishing agent, the self-cleaning function of the filter bag fabric is realized.

Description

technical field [0001] The invention belongs to the technical field of filter bag fabric preparation, and in particular relates to a self-cleaning and antistatic high-temperature-resistant filter bag fabric and a preparation method thereof. Background technique [0002] With the continuous improvement of the country's environmental protection requirements, some factories that emit waste gas and dust pay more and more attention to environmental protection, and they use more advanced dust removal equipment to deal with the emission of waste gas and dust. As an efficient flue gas treatment and dust removal equipment, the bag filter is widely used in steel plants, power plants and other factories. The high temperature filter bag is an important part of the bag filter. Usually, the cylindrical filter bag is hung vertically in the filter bag. The fabric of the filter bag plays a decisive role in the performance of the filter bag. It is easy to remove dust, efficient in filtration ...
