Abstract

The invention discloses a ferrocene triazole ionic-type nitrogen-enriched energetic metal complex and a preparation method thereof. The ferrocene triazole ionic-type nitrogen-enriched energetic metalcomplex adopts a structural formula as follows: FORMULA, wherein M represents Cu<2+> or Zn<2+>, L is 1, 1, 3, 3-tetracyanoacrylate ion, picrate ion or trinitroresorcinate ion, and n is 1 or 2. The ferrocene triazole ionic-type nitrogen-enriched energetic metal complex is high in nitrogen content; through introduction of carbon-nitrogen double bonds, the conjugacy of a whole system is increased; the ferrocene triazole ionic-type nitrogen-enriched energetic metal complex is unlikely to volatilize under a natural condition, is good in thermal stability, has relatively high formation heat and combustion heat and extremely low vapor pressure and volatility, and has relatively good combustion catalyzing effect on main components, namely ammonium perchlorate and hexogen, of a composite solid propellant. The preparation method of the ferrocene triazole ionic-type nitrogen-enriched energetic metal complex preparation method is simple, the cost is low, the yield is high, and the defects that theexisting ferrocene-type combustion catalyst synthesizing process is cumbersome, the cost is high, the synthesis period is long and the like are overcome.

Description

Technical field [0001] The invention belongs to the technical field of solid propellants, and specifically relates to a class of ferrocene triazole ion-type nitrogen-rich energetic metal complexes and a preparation method thereof. Background technique [0002] Ferrocene derivatives are metal-organic π-complexes. They are used as hydroxy-terminated polybutadiene (HTPB) and carboxy-terminated polybutadiene (CTPB) propellants to burn rate catalysts than inorganic iron oxide, iron Catalysts such as iron cyanide are more effective. Certain ferrocene derivatives can not only improve the mechanical properties and process performance of the propellant, but also have the effect of reducing the pressure index. [0003] As a burning rate regulator, ferrocene and its derivatives are mainly used in composite solid propellants and have played a huge role in the fields of aerospace and strategic and tactical missiles. According to reports, the mixture of volatile ferrocene derivative steam and ...
