| titleOfInvention | Preparation method of polytetrafluoroethylene composite film material with high filler filling amount |
| abstract | The invention relates to a method for preparing a polytetrafluoroethylene composite film material with high filler filling amount, which mainly comprises the steps of preparing the polytetrafluoroethylene composite film material with the inorganic filler filling amount of more than 20wt% by the methods of high-speed mixing, cold pressing and blank forming, sintering and forming, turning and film forming and calendering post-treatment, and preparing the inorganic filler/polytetrafluoroethylene composite film material with controllable film structure, excellent mechanical property, conductivity, heat conductivity and wear resistance by the design of various inorganic filler dispersion forms with different functions and the regulation and control of a preparation process. The high-filler-filling-amount polytetrafluoroethylene composite membrane material has the advantages of controllable membrane structure, excellent mechanical property, flexibility and adjustability in functionality, simple equipment and process and suitability for industrialization, and has remarkable research value and application prospect in the field of high-performance and functionalized PTFE composite membrane materials. |
