N2 - Waterborne polyurethane(WPU) was prepared with TDI, DL-400 (M = 340),DMPA and BDO as main materials, whose structure was characterized by FTIR . Polyurethane-acrylate (PUA) latex was synthesized through the method of the seed-latex polymerization with WPU, water and butyl acrylate as starting materials, two kinds of initiator, AIBN and (NH4)2S 2O8-NaHSO3. Latex particles shape of PUA were determined through TEM, and the results indicated that PUA latex with core-shell structure was synthesized with AIBN as initiator, whose shell were black polyurethane particles and core white polyacrylate ones. PUA latex initiated by (NH4)2S2O8-NaHSO3 has no core-shell structure. The method was used for the first time to deposit core-shell latex to coat RDX with 10% KAI (SO4)2 • 12H2O solution, distilled water,40'C. Through SEM, the surface of RDX was observed to have been covered with a layer of even film after being coated with PUA, and the particles among RDX were perfectly dispersed. propellant; RDX; waterborne polyurethane; polyurethane-acrylate; core-shell structure; coating.
