Theoretical aspects creation of composite materials (CM) based on the original kaolinite and polydisperse graphite nanoplatelets (GnP) were analized. Based on analysis literary sources were found that during wet mixing of the kaolinite and GnP creation the heterophasic hydrophilic-hydrophobic system kaolinite-GnP takes place. The homogeneous allocation GnP in kaolinite matrix for such system dependents on the parameters which regulates different type of interparticle interactions. To regulate of interparticle interactions beetwen the kaolinite and GnP were used nonionic surfactant Triton X-305 and changing pH value of the dispersed environment. GNp powder was produced by sonication from thermally expanded graphite (TEG). Main properties of the produced GNp powder were investigated and were found correlation with technological modes manufacture. The way of moist pressing and subsequent sintering CM based on the original kaolin and GnP. The influence of stabilization of kaolinite-GNp by using nonionic surfactant Triton X-305 on the main functional properties of CM were experimentally investigated. It was found that to use of the nonionic surfactant Triton X-305 ceteris paribus leads to lower porosity on 1,5?2 % increases conductivity by 20 % and increases border compressive strength by an average of 9 %. |
