Abstract: An enhanced soluble polytetrafluoroethylene and a preparation method therefor. The method comprises the following steps: stirring a formula amount of PFA and PEKK at a temperature of 110-120°C for about 30 min to mix the PFA and the PEKK uniformly, so as to obtain a mixture of the PFA and the PEKK; and melt extruding the mixture of the PFA and FEP obtained after processing in a melt extruder, and cooling same to obtain a product. The enhanced soluble polytetrafluoroethylene (PFA) is prepared by blending, melt extruding and molding the PFA and the polyether ketone ketone (PEKK) which have good compatibility. When the proportion of PFA is relatively small, the material obtained by extrusion molding has good flexibility, but the heat resistance and corrosion resistance are reduced; when the proportion of PFA is relatively large, the material obtained by extrusion molding has flexibility superior to pure PFA material, and has the characteristics of high resistance to corrosion and heat, and the tensile property is also enhanced, ameliorating the problems of melt fracture and poor molding occurring in the extrusion process of pure PFA.
