Description
Technical field
The invention belongs to blasting material field, be specifically related to a kind of coated blast band rope and preparation technology thereof.
Background technology
Primacord is a kind of strip initiating equipment transmitting detonation wave, needs other initiating equipments to ignite, and is passed by detonation wave
To the other end.Primacord is mainly used in multiple explosive loading of simultaneously detonating, and its advantage is that use is safe and simple, not by stray electrical
The interference of stream, thunder and lightning and electrostatic etc..
But, traditional primacord makes, production technology also exists many problems.Tradition primacord shell mainly has cotton
Line, plastics and metal tube.First, mild detonating cord making step is loaded down with trivial details, and workload is huge.Mild detonating cord manufacturing process
Generally comprise flexible metallic hose powder charge, stretch, three parts of annealing.Wherein, degree of packing needs strict control, and is difficult in pipe
Filling explosive；Stretching typically requires and constantly reduces drawing die aperture repeated stretching, typically can stretch tens times, the hugest.
Secondly, during repeated stretching tradition primacord, the ductility of metal shell is substantially reduced, and easily produces fracture.Furthermore, repeated stretching
During explosive density be continuously increased, there is the deterrent of accidental explosion；Increase in the annealing process that metal shell is flexible, temperature
Degree controls the most proper potential danger that also can there is blast with annealing time.
Being the primacord of shell for cotton thread or plastics, owing to the intensity of shell itself limits, degree of packing is little, at some
Occasion can not reach requirement.
In sum, for ensureing personal safety as well as the property safety, improving production efficiency, modern society needs badly finds novel primacord
To adapt to the development of society.
Summary of the invention
For overcoming the shortcoming of prior art, in conjunction with the present situation that the most many metals (such as ferrum, aluminum, copper) are cheap, this
Bright devise a kind of novel primacord and production technology thereof.Compared to tradition primacord processing technology, only need to be by explosive, binding agent
The viscoloid formed is applied on the metal tape designing width and thickness according to demand, utilizes the curling of mould one-off drawing i.e.
Can reach normal propagation of explosion effect.After moisture is evaporated, utilize the character that both sides, gap aluminium flake height is different, primacord can be continued
Through small-bore drawing die, form that diameter is less, line density is bigger primacord；Also can compress it, formed flat or
The primacord of other shapes, can be in different applications.The present invention is simple to operate, with low cost, and explosion transfer performance is excellent, safety
Property is the best, is greatly improved production efficiency.
The purpose of the present invention is realized by techniques below scheme: the preparation technology of a kind of coated blast band rope, material therefor
Including two parts: elongate strip metal tape and explosive.The method comprises the following steps:
Step (1), by explosive (as hexogen, too peace, HMX) with binding agent (such as polyvinyl alcohol, osseocolla, plant
Glue) mixing, and be stirred until homogeneous；
Step (2), the thick colloid upper step obtained uniformly extrude, spread upon on metal tape, utilize stretching die simultaneously
Have and metal tape curling is become round tube shape, be filled with explosive colloid, and ensure that pipe exists small-gap suture, and both sides, gap aluminum
Sheet height is different；
Step (3), the metal tube including colloidal explosive is placed in add in hot tank heat so that it is in moisture from small-gap suture
Volatilization；
Step (4), by primacord through the drawing die of different pore size, be stretched to required size and shape；
Step (5), at one layer of plastics of metal tube surface uniform application, improve its intensity and water proofing property.
Further, described metal shell is different from tradition primacord, and described metal shell is by elongated metal tape warp
Curl into after overstretching mould, the size of metal tape and the aperture of drawing die can be selected as required.
Further, described metal shell is cheap, can be mass-produced.
Further, described processing technology is that safety is high, during due to filling explosive, in advance by explosive and binding agent
Liquid mixing, therefore will not occur accidental explosion accident, significantly ensure personal safety as well as the property safety in drawing process.
Further, after described crimping by stretching, primacord still is able to ensure good ductility and flexibility, it is not necessary to move back
Fire, ensure again that safety.
Further, described heater artistic skill enough ensures that the moisture in metal shell fully evaporates, and will not time fried
Medicine decomposes or blast, safe and reliable.
Further, described novel primacord can normal propagation of explosion.
Further, loading density is higher than the primacord that cotton thread, plastics are shell, and shape can be difformity
(such as column, strip), meets the demand of multiple fields.
Further, described at one layer of plastics of shell uniform application, technique is simple, it is easy to operation, can improve primacord
Intensity and water proofing property.
The present invention provides a kind of coated blast band rope, and this coated blast band rope is to be made by above-mentioned preparation technology to obtain
's.
Compared with prior art, the method have the advantages that
(1) powder charge is simple, and production efficiency is high；
(2) powder charge is the colloid that explosive mixes with binding agent, will not produce accidental explosion；
(3) metal tube curled into keeps good ductility, it is not necessary to annealing；
(4) degree of packing is high relative to the primacord that cotton thread, plastics are shell, and can be fabricated to different shapes, such as circle
Column, flat strip shaped, be suitably applied multiple fields.
