Abstract

The invention discloses a PTFE (polytetrafluoroethylene) fiber for denitration. The fiber is prepared from PTFE dispersion resin, aviation kerosene and manganese catalyst powder. The invention further provides a preparation method of the PTFE fiber for denitration. The method comprises the steps of raw material inspection, storage and refrigeration, ingredient mixing, standing and curing, prepressing forming, pushing forming, heat preservation in a water tank, rolling for film forming and filamentation of short fibers. The PTFE fiber and the preparation method have the advantages that a functional filter material for dedusting and denitration can be directly prepared from the PTFE fiber; the preparation method of the PTFE fiber is short in process, a denitration catalyst is evenly dispersed in the fiber, and the denitration function is stable and efficient.

Description

technical field [0001] The invention relates to the field of fiber and its manufacture, in particular to a polytetrafluoroethylene (PTFE) fiber and its manufacturing method. Background technique [0002] Polytetrafluoroethylene (PTFE) is recognized as the "King of Plastics". It is the most used fluoroplastic in the world. Polytetrafluoroethylene is excellent in various properties such as heat resistance, light resistance, chemical resistance, electrical insulation, and sliding properties, so it is used in a wide range of fields mainly in the mechanical, chemical, and electrical fields. One of the articles containing polytetrafluoroethylene is polytetrafluoroethylene fiber, and polytetrafluoroethylene fiber is expected to be used in various fields based on the above-mentioned various characteristics of polytetrafluoroethylene. [0003] At present, the existing polytetrafluoroethylene fiber filter material does not have the denitrification function. A polytetrafluoroethylene...
