Embodiment 1

[0031] A process for preparing nano-diamond black powder by detonation, including preparation of explosives, explosive molding, detonation preparation, and detonation preparation of nano-diamond black powder. The explosive molding is specifically:

[0032] Pour the prepared Tihei explosive liquid into a hollow spherical mold 1; 4 to 20 protrusions 2 are evenly distributed on the inner surface of the spherical mold 1, and all of them point to the center of the spherical mold 1; the protrusions 2 are provided with priming charges 3, and the priming charges 3 are provided with a cavity 4 matching with the protrusions, and are sleeved on the protrusions 2; after the ladder black explosives fill the entire interior of the spherical mold 1, maintenance is carried out. Until it is completely cooled to room temperature, after the Tihei explosive liquid is solidified, the spherical mold 1 is removed to obtain a spherical explosive ball 5, the detonating powder column 3 is evenly distrib...

Embodiment 2

[0035] On the basis of embodiment 1:

[0036] The preparation of explosives specifically includes: heating the TNT explosive powder to completely melt it into a liquid state, then adding the RDX explosive powder, and stirring continuously to completely dissolve the TNT explosive powder into the TNT explosive liquid to obtain the TNT explosive liquid.

[0037] Preferably, the weight ratio of the TNT explosive powder to the RDX explosive powder is 40:30.

Embodiment 3

[0039] On the basis of embodiment 1:

[0040] The preparation of explosives specifically includes: heating the TNT explosive powder to completely melt it into a liquid state, then adding the RDX explosive powder, and stirring continuously to completely dissolve the TNT explosive powder into the TNT explosive liquid to obtain the TNT explosive liquid.

[0041] Preferably, the weight ratio of the TNT explosive powder and the RDX explosive powder is 70:60.

Abstract

The invention relates to a process for preparing nano-diamond black powder by virtue of detonation, and belongs to the technical field of preparation of nano-diamond black powder. According to the process, due to the improvement of the explosive forming process, a spherical explosive ball which takes initiating explosive columns as initiating points is prepared by using a spherical mold, the initiating explosive columns are uniformly distributed and embedded on the surface of the spherical explosive ball, 4-20 initiating points which are uniformly distributed on the surface of the spherical explosive ball are formed by cavities on the initiating explosive columns, so that the final nano-diamond black powder prepared by detonation has the advantages that the quality is high, the performance is good, the particle size distribution is uniform, the dispersion is easy, the subsequent treatment process is simple, and the yield of the nano diamond can be improved.

Description

technical field [0001] The invention relates to a preparation process of nano-diamond black powder. Specifically, the invention relates to a process for preparing nano-diamond black powder by detonation, which belongs to the technical field of preparation of nano-diamond black powder. Background technique [0002] Nano-diamond has been developed more than 30 years ago, but its application was limited to the field of abrasives such as polycrystals and polishing agents in the past. With the deepening of people's understanding of the properties of nano-diamonds, nano-diamonds have been applied in metal coating, lubricating oil, magnetic recording systems, medicine and other fields, and the application fields are still expanding. [0003] The preparation process of nano-diamond includes two parts: detonation ash (black powder) synthesis and purification. [0004] In the existing nano-diamond black powder preparation method, since the explosive powder column used for production ...
