High-strength dispersed polytetrafluoroethylene resin as well as preparation method and application thereof

The invention relates to the technical field of chemical engineering, in particular to a preparation method of high-strength dispersed polytetrafluoroethylene resin. The invention relates to a preparation method of high-strength dispersed polytetrafluoroethylene resin, which adopts a dispersion polymerization method and comprises the following steps of: adding a modified monomer I and a modified monomer II with different polarities to carry out copolymerization modification on tetrafluoroethylene when tetrafluoroethylene is polymerized to 90% or more, and preparing the high-strength dispersed polytetrafluoroethylene resin by controlling the polymerization reaction and optimizing a coagulation process. According to the present invention, the dispersed polytetrafluoroethylene resin can form the high-strength fiber network structure during the paste extrusion molding process, and can be used for processing the long fiber product with characteristics of high strength and low elongation at break. 本发明涉及化工技术领域，具体涉及一
