Abstract: The present invention discloses an aramid high temperature resistant filter cloth with easy ash cleaning function and a preparation method thereof, which comprises a base fabric layer in the middle, consisting of NOMEX fiber and meta-aramid fiber laying net forming a microfiber dust-facing surface layer, and a meta-aramid fiber laying net with a breathable and clean air surface layer, and a PTFE emulsion impregnating layer containing high fineness talc. The present invention is to lay the substrate with NOMEX fiber and meta-aramid fiber, and composite it into a felt to make a filter cloth with a PTFE base fabric that is resistant to corrosion and oxidation, which increases the strength and filtration accuracy of the filter cloth; At the same time, PTFE emulsion containing highly refined talcum powder is impregnated during the preparation process, so that the surface of the filter cloth has a certain hydrophobicity, and the acid and alkali corrosion resistance of the filter cloth is improved. It also increases the smoothness of the surface of the filter cloth, increases the dust peeling rate, has a small dust holding capacity, and is easier to clean ash.
