TATB/RDX/PSt/GO composite microsphere and preparation method thereof

The invention belongs to the technical field of explosive coating sensitivity reduction, and particularly relates to a TATB/RDX/PSt/GO composite microsphere and a Pickering emulsion polymerization preparation method of the TATB/RDX/PSt/GO composite microsphere. Solid particles GO are adopted as a stabilizer, TATB/RDX/PSt/GO composite microspheres are prepared through a Pickering emulsion polymerization method, the composite particles are characterized through SEM, XRD and DSC, and the impact sensitivity is tested. Results show that the prepared TATB/RDX/PSt/GO composite microspheres tend to be spherical in morphology and have few defects; through XRD (X-Ray Diffraction), the TATB/RDX/PSt/GO composite microsphere has the characteristic diffraction peaks of RDX, TATB and GO at the same time, and the crystal forms of RDX and TATB are not changed; dSC shows that the activation energy of two decomposition peaks of RDX and TATB in the TATB/RDX/PSt/GO composite microspheres is improved compared with that of the raw
