Title Preparation and application of multiple acetylene-termine deterrent precursor。

Abstract In order to solve the surface deterring technology problem of azidenitramine gun propellant with high plasticizer concentration, this paper selected multiple acetylene-terminated compound as deterrent precursor and introduced them into deterring system。Crosslinking reactivity between them and azide group form deterrent of macromolecular of network structure。 Two kinds of deterrent precursors were synthesized among the three phloroglucinol propargyl ether (TPPG), three propargyl isocyanurate (TPIC)。 Crosslinking reactivity between them and glycidylazide polymer(GAP) were researched and they were characterized with FTIR, 1H-NMR and DSC。 And carried out a study about application of surface propellant of gun propellant。The results shows: the product were the target compounds。 TPIC and TPPG can react with GAP at low temperature (60 ℃)。The sequence for cross-linking reactivity with GAP of four curing agents is TPPG>TPIC。The azidenitramine propellant was deterred in rotary drum,it used TPPG and TPIC as surface deterrent precursor,deterred propellant has obvious increasing combustion。

Keywords gun propellant;surface deterring;deterrent;multiple acetylene- terminated compound;cross-linking reactivity。
