Abstract
The present invention relates to a kind of explosion methods to synthesize nano composite oxide, by being exploded in a limited space using explosive, generate high temperature and pressure, can continue that secondary or even multiple reaction occurs, various metals powder can be made to be converted to nano composite oxide, gained nano composite oxide is sieved, the nano composite oxide that the height that partial size is 20-100nm mixes can be obtained.Single oxidation physical performance may not have the whole requirements for making certain material, a kind of good means is then needed to obtain two kinds or even a variety of composite oxides at this time.The present invention can be properly arrived at this and want ball, and simple process, and obtained good quality of product is worthy to be popularized.
Description
Technical field
The present invention relates to a kind of novel processing steps of explosive manner synthesis nano composite oxide.
Background technique
There is no any single substance to be perfectly, almost all of quality material is all the mixing of two or more substances
Object.Such as, our common white pigments have titanium white and zinc white.The ingredient of titanium white is titanium oxide, there is the stronger advantage of covering power, but
Color is easy jaundice.The chemical component of zinc white is zinc oxide, and covering power is easy to change not as good as titanium white, but not, thus, if being mixed
Uniformly, then the respective advantage of the two can be obtained.
Pressure after detonation reaction zone in high-temperature high-voltage reaction area may be up to 10-30GPa, and temperature is up to 3000-4000
Degree Celsius, it is spread and is grown by vapor reaction, the product grain of synthesis is typically small, usually nanometer grade.Explosive charge shape
At shock wave have pressure high, action time is short, the high feature of temperature, synthesizes nano composite oxides using shock wave
Object.
Summary of the invention
In order to solve the problems, such as to obtain the uniformly mixed nano composite oxide of height, the present invention provides a kind of explosion sides
Formula synthesizes nano composite oxide.The method can produce the nano composite oxides that the height that partial size is 20-100nm is uniformly mixed
Object, and simple production process.
The technical solution adopted by the present invention are as follows:
A kind of method of explosive manner synthesis nano composite oxide, includes the following steps:
A, part metals powder is added in explosive, is uniformly mixed；
B, using blower device, make have certain density metallic dust in destructor；
C, mixture is placed in destructor, the volume of device is 53L；
D, primer is collected explosion product, is screened to product.
In the step a expired military explosive be hexogen, TNT etc., metal powder used be iron powder, titanium valve, zinc powder,
Copper powder etc..
In the step d, explosion terminates about two ten minutes later, is collected to explosion ash, product is first used to 100 mesh/English
The screening of little progress row, then removes moisture removal for 100 DEG C of sample baking oven obtained to obtain dry powder, then use chamber type electric resistance furnace
It is heated to 500-1000 DEG C by double crucible method heat treatment in the environment of anaerobic, heating roasting 2-4h.
The resulting nanosize metal oxide of the above method, partial size 20-100nm can be used for making metallic pigments.
Destructor described in the above method is ball-type, and the outer wall of a diameter of 100cm, destructor consist of three layers,
Innermost layer is the stainless steel (440-C) of 5mm thickness, also posts the electro-insulating rubber of wiped clean in its inner wall；Centre is 10cm thick
Sand；Outermost layer is the stainless steel (154CM) of 2mm thickness.In use, manufactured dedicated composite explosives pack is plugged No. 8 industry
Electric cap one is sent out, and is then hung and is fixed at 2/3rds of steel drum height, has reception explosion powder in the bottom of pack
Collection device, the top for the spherical tank that explodes is covered using clean rubber skin, then by the door seal for the pillbox that explodes it is good after, utilize
Initiator ignites composite explosives pack.About two ten minutes later after reaction, collects the explosion ash being deposited on collecting board.
The innovation of explosive synthesizing nano composite oxides is to be different from conventional chemical method, the conjunction of the approach such as method for constructing
At nano material, but the approach for using explosion of " bold " carrys out nano materials, it is characterized in that process is simple, bangs quick-fried
When easily generate nanometer spherical particle, can low cost obtain we needs high quality nano composite oxides, existing section
Value is ground, also there is very high market value.
