| description | The invention belongs to the field of polytetrafluoroethylene resin, and particularly relates to easy-to-process and high-thermal-conductivity filled polytetrafluoroethylene dispersion resin and a preparation method thereof. The surface-modified metal powder and the inorganic filler are used for filling the polytetrafluoroethylene dispersion resin, lap joint of a heat conduction network is achieved through efficient matching of the flaky inorganic filler/spherical metal powder, and the dispersion condition and the orientation state of the filler in a polytetrafluoroethylene matrix are improved; the hydrophobic modifier is used for carrying out surface hydrophobic modification on the metal powder, after the non-aqueous organic solvent is added, metal powder filling is more uniform, later finished product dehydration and particle forming are facilitated, the polytetrafluoroethylene dispersion resin is uniform in particle size and small in extrusion pressure fluctuation, and later oil mixing and forming processi |
