| titleOfInvention | A kind of preparation method of nano-calcium carbonate/polytetrafluoroethylene (PTFE) composite polymer material |
| abstract | The invention belongs to nano polymer composite material field, more particularly to the preparation method of a kind of nano-calcium carbonate/polytetrafluoroethylene (PTFE) composite high-molecular new material.The polymerization procedure of this method is：Nano-calcium carbonate is made into modified emulsion first, then after being dispersed with stirring in polymeric kettle according to a certain ratio with deionized water, emulsifier, initiator, stabilizer, buffer uniformly, it is passed through tetrafluoroethylene monomer under anaerobic, and nano-calcium carbonate/polytetrafluoroethylene (PTFE) composite material is prepared by polymerisation under certain temperature and pressure.The present invention forms modification grafting active site on Nano particles of calcium carbonate surface in advance, dispersion copolymerization method is used to carry out free radical polymerization in particle surface by tetrafluoroethene again, the phenomenon that particle is easy spontaneous reunion can be eliminated, keep Nano particles of calcium carbonate well dispersed in polytetrafluoroethylene material, and can be carried out on original polymerization reaction kettle, it is conducive to industrial large-scale production. |
