Abstract

The invention specifically relates to a mixture containing fluororesin and a preparation method thereof, belonging to the field of communication materials. A prepreg prepared by impregnating a glass fabric in dispersion liquid of the mixture containing fluororesin and then carrying out drying and the like has uniform glue content, good impregnation quality, strong resin adhesion, smooth surface and appropriate toughness and viscosity. The invention also relates to a high-frequency copper clad laminate prepared from the prepreg, or a film or copper foil made of the mixture containing fluororesin. The prepared copper clad laminate has good thermal-mechanical properties, excellent dielectric properties and high copper foil strength, and can meet requirements on the comprehensive properties of substrate materials in the field of high-frequency communication. According to the invention, the processing properties of traditional fluororesin are greatly improved by using fluorine-containing resin with a low melting point; and a coupling agent is cooperatively used, so interaction between an inorganic filling material and glass fabric and a resin matrix is improved, dispersibility of the inorganic filling material, processing aids and the like in the fluororesin is enhanced, and the overall performance of the copper clad laminate is made more stable.
