| titleOfInvention | Manufacturing method of modified polytetrafluoroethylene copper-clad plate |
| abstract | The invention discloses a method for manufacturing a modified polytetrafluoroethylene copper-clad plate. The method comprises the following steps: (1) modifying the polytetrafluoroethylene treated by the sodium-naphthalene by adopting a grafting monomer to obtain modified polytetrafluoroethylene; (2) modifying the filler by using a coupling agent to obtain a modified filler; (3) dispersing the modified polytetrafluoroethylene obtained in the step (1) in kerosene, then adding the modified filler obtained in the step (2), and mixing to obtain slurry; (4) and (4) coating the copper foil by adopting the slurry obtained in the step (3), and pressing to obtain the modified polytetrafluoroethylene copper-clad plate. The copper-clad plate pressed by the method does not contain glass fiber cloth, the glass weaving effect is effectively avoided, and the polytetrafluoroethylene copper-clad plate manufactured by pressing has the advantages of stable dielectric property, low thermal expansion coefficient, good dimensional stability and the like. |
