| titleOfInvention | A kind of preparation method of modified polytetrafluoroethylene powder |
| abstract | The invention discloses a preparation method of modified polytetrafluoroethylene powder, comprising: (1) coating and modifying hard filler powder with polydopamine to obtain polydopamine-modified hard filler powder; (2) applying polydopamine The polydopamine-modified hard filler powder is added to deionized water, and then the viscous biomass is added to obtain an aqueous dispersion of the ionized polydopamine-modified hard filler; (3) the water of the ionized polydopamine-modified hard filler is added The dispersion is filtered and dried to obtain the ionized polydopamine modified hard filler powder; (4) the ionized polydopamine modified hard filler is added to the polytetrafluoroethylene emulsion to obtain a broken emulsion; (5) the broken emulsion is filtered and mixed. After drying, modified polytetrafluoroethylene powder is obtained. The invention has the advantages of simple process and good product performance. |
