The method comprises the steps of dissolving magnesium acetate in absolute alcohol and conducting solvent thermal treatment at the temperature ranging from160 to 20 DEG C to get a magnesic precursor; and placing the precursor into a muffle furnace and conducting calcination at the temperature of 450 DEG C for 2 hours to get white MgO nano-catalyst. The material has a specific surface area of 230m<2>/g and an aperture of 5nm. The temperature of ammonium perchlorate high-temperature decomposition is reduced by 78 DEG C and the apparent heat of decomposition is increased to 1059 J/g from the previous 371J/g.
Description
Technical field:
The present invention relates to the high-energy solid propellant field, especially relate to a kind of high-specific surface area MgO nano-catalyst material and synthetic method thereof.
Background technology:
Solid propellant is the power source material of rocket engine, plays an important role in guided missile and space technology development.Ammonium perchlorate (AP) is a high energy oxidizer commonly used in the solid propellant.Its thermal decomposition characteristic has material impact to the combination property of solid propellant.Pure The Thermal Decomposition of Ammonium Perchlorate is divided into low-temperature decomposition and two processes of pyrolytic, and the energy when having limited its burning discharges.In order to improve the combustion speed of composite solidpropellant, need make the interval reach as far as possible of The Thermal Decomposition of Ammonium Perchlorate reaction temperature.Simultaneously,, need to improve the The Thermal Decomposition of Ammonium Perchlorate reaction severity, make it to focus on the release of heat in order to improve the specific impulse value of solid propellant.Adding little amount of catalyst is the effective ways of regulating propellant burning property.Regulate the focus that propellant burning property has become research with nanocatalyst, study the more Nano metal powder (especially aluminium powder) that normally in solid propellant, adds at present.These Nano metal powders are normally to be made by wire (or paper tinsel) electricity consumption explosive method in inert gas (as Ar), and preparation process needs complex apparatus and higher cost.And when propellant burnt in solid engines, the easy fusion of aluminium powder was condensed into aluminium and coagulate drips, and these aluminium drop in the engine usually with fixed attention can not completing combustion, causes performance loss.For this reason, research and development novel nano catalyst, the combination property of raising solid propellant, just particularly important.
The objective of the invention is on the basis of solid propellant present Research of making thorough investigation and study, proposed a kind of new MgO nano-catalyst material that improves the solid propellant performance and preparation method thereof that can be used for.
Studies show that nano-MgO can significantly reduce the high-temperature decomposition temperature of ammonium perchlorate, improve the combustibility of propellant.
Summary of the invention:
The present invention proposes a kind of method of synthesising mesoporous MgO nano-catalyst material, purpose is to prepare Stability Analysis of Structures, high-specific surface area, has good ammonium perchlorate catalytic activity, can develops into the high-energy solid propellant nano catalytic material of new generation that has a extensive future.
The present invention adopts two-step method to prepare the MgO nanocatalyst, and detailed process is as follows: magnesium salts is dissolved in the absolute ethyl alcohol, changes reactor over to behind the formation clear solution, be heated to 140-200 ℃, insulation.After reaction finished, cool to room temperature filtered, and collects, and must contain the presoma of magnesium.Then presoma is calcined in Muffle furnace and obtained the MgO nanocatalyst.
We prepare specific area by above method is 230m
2/ g, the aperture is～5nm MgO mesoporous nano catalyst material.This material has good ammonium perchlorate catalytic activity, can effectively make the high-temperature decomposition temperature of ammonium perchlorate reduce by 78 ℃, the low-temperature decomposition peak almost disappears, and makes two decomposable processes of ammonium perchlorate change a tangible exothermic decomposition into, and apparent heat of decomposition increases to 1059J/g by original 371J/g.
MgO nanocatalyst of the present invention is controlled specific area and the catalytic performance of MgO by accurate control preparation condition; Compare with the nanocatalyst (as Nano metal powder) of existing other structure, MgO nanocatalyst of the present invention has good ammonium perchlorate catalytic activity, and technology of preparing is simple, equipment is less demanding, with low cost.In addition, the HCl reaction that MgO can decompose produce with ammonium perchlorate can effectively reduce solid propellant in use to the pollution of environment.Thereby, have great application prospect in the solid propellant field.
