| Abstract: | In order to improve ablation resistance of solid propellant coating layer,the isocyanurate-modified polyurethane elastomer(IMPUE) used in adhesion system of solid propellant coating layer was designed and synthesized by using hydroxyl-terminated carbon nitrogen heterocyclic chlorinated polyether polyol and modified liquid 4,4'-diphenylmethane diisocyanate(L-MDI) as main raw materials.The results show that IMPUE has good mechanical properties.Compared to conventional polyurethane elastomer,its thermal proper... |
