不饱和聚酯树脂插层高岭土纳米复合材料的制备

In the paper, nanocomposite of kaolinite-unsaturated polyester resin is prepared by mixing Maleic anhydride, Phthalic anhydride and the treated 1,2-propanediol, which is initially intercalating with 2.5%、5%and 7.5% kaolinite- Dimethysulfoxide(Kao-DMSO), using the in situ intercalative polymerization. It shows that, by XRD and IR, the monomer or the polymer can intercalate into the interlayer of kaolinite and attach to the surface of lamellar structure; Owing to the energy released from polymerizing reaction, the superposed layer can be exfoliated into fragments in nanometer grade, which are dispersed uniformly into the resin. It is also observed from TG that the fragments can be concentrated on the surface when the resin, containing higher enthalpy and nonflammable kaolinite, burns. It contributes to blocking energy transfer and flame retardance.
