Abstract
Porous surface the invention discloses the mixed with nano metal of low energy near-infrared laser direct initiation pacifies very much the preparation method of explosive, including：Can be in the solvent pacified very much of micro dissolution, explosive and a small amount of Nano metal powder ultrasonic wave mixed processing will be pacified very much, micropore is formed in too peace particle surface by the slightly-dissolving action of solvent, enters Nano metal powder by ultrasonic mixing effect and pacifies in explosive surface holes very much, uniformly mix.Further pacify very much explosive by filtering, being dried to obtain the porous surface of mixed with nano metal, mechanical sensitivity is not substantially change, but near-infrared laser initiation energy significantly reduces.Porous surface the invention also discloses a kind of mixed with nano metal of low energy near-infrared laser direct initiation pacifies very much explosive.The present invention reduces the energy needed for near-infrared laser direct initiation on the basis of too peace explosive mechanical sensitivity is not changed, and is advantageously implemented the optical fiber connection of laser direct initiation technology and weaponization application.
Description
Technical field
The present invention relates to a kind of explosives and preparation method thereof, and in particular to a kind of nanogold of near-infrared laser direct initiation
The porous surface for belonging to doping pacifies very much explosive and preparation method thereof, belongs to energetic material field.
Background technology
Laser initiation is not that one kind is highly suitable for weapon system by the electromagnetic environments interference effect such as electrostatic, electromagnetic radiation with it
The detonating technique of system.Since the eighties, with the miniaturization of laser and the appearance of low loss fiber, laser initiation technology by
Stepping enters the practical stage.This project is included in emphasis key technology system by the nineties, U.S. Department of Defense, Ministry of Energy and the Ministry of Aerospace Industry
Row even more advance the process of its application.
Laser initiation explosive is generally divided into Laser Driven Flyer Plates detonation and the direct ablation explosive initiation two ways of laser.Its
Middle laser ablation explosive initiation needs laser sensitive explosive, but newly synthesized laser-sensitive explosive is generally the coordination of metal
Compound, mechanical sensitivity is also very high, and safety is poor.Miniaturization in view of guided missile, optical fiber connection, generally using volume compared with
Small near infrared laser, and general explosive does not absorb near-infrared laser, cause to detonate needed for laser energy it is larger, it is difficult to
Realize the weaponization application of laser initiation.
The present invention is realized by the slightly-dissolving action of solvent pacifies very much explosive porous surface, is further received by adding metal
Rice grain and ultrasonic mixing realize Uniform Doped.The mixed with nano metal porous surface of preparation pacify very much the mechanical sensitivity of explosive with too
Peace is suitable, but the energy of its near-infrared laser detonation significantly reduces.
Invention content
The low energy near-infrared laser reduced the purpose of the present invention is to provide a kind of energy of near-infrared laser detonation is straight
The porous surface for picking up quick-fried mixed with nano metal pacifies very much the preparation method of explosive.
The invention is realized in this way：
The porous surface of the mixed with nano metal of low energy near-infrared laser direct initiation pacifies very much the preparation method of explosive, packet
It includes：
It can will pacify very much explosive and a small amount of Nano metal powder ultrasonic wave mixed processing in the solvent pacified very much of micro dissolution,
Micropore is formed in too peace particle surface by the slightly-dissolving action of solvent, Nano metal powder is made to enter too by ultrasonic mixing effect
Pacify in explosive surface holes, uniformly mix.Further by filter, be dried to obtain the porous surface of mixed with nano metal pacify very much it is fried
Medicine, mechanical sensitivity are not substantially change, but near-infrared laser initiation energy significantly reduces.
Further scheme is：
The grain diameter of the too peace explosive is less than 1mm, and purity is more than 99%.
Further scheme is：
Nano metal powder, is metallic aluminium powder, zirconium powder, nickel powder or titanium valve, diameter of particle 50-200nm, Nano metal powder
Dosage is no more than the 2% of too peace charge weight.
Further scheme is：
The solvent is to being equipped with very much certain solubility, but solubility is not more than 20mg/g.
Further scheme is：
Ultrasonic wave mixed processing is to be ultrasonically treated 2-10min with supersonic wave cleaning machine.
Further scheme is：
The wavelength 800-1200nm of the near-infrared laser.
The invention also discloses a kind of low energy near-infrared laser direct initiation mixed with nano metal porous surface too
Pacify explosive, be prepared by preparation method provided by the invention.
Further scheme is：
The near-infrared laser initiation energy of the explosive is less than 50mJ.
The explosive can be detonated directly in the case where being acted on compared with the near-infrared laser of low energy, reduce the energy to inputting laser
It is required that reducing the volume of laser, can be inputted by optical-fiber laser.
The present invention makes to pacify very much particle surface microporous by the slightly-dissolving action of solvent, further makes to receive by ultrasonic mixing
Rice metal powder enters in the hole to be formed, and realizes that too peace and metal uniformly mix.In the base for not changing too peace explosive mechanical sensitivity
On plinth, the energy needed for near-infrared laser direct initiation is reduced, is advantageously implemented the optical fiber connection of laser direct initiation technology
With weaponization application.
