Problems solved by technology

[0004] Obviously, as far as the structure of the detonator is concerned, its production scale and resource consumption, etc., it can be seen that there is still a certain complexity in the structure, and the investment and consumption are quite high, which makes the cost of a single detonator relatively high. growing trend

Embodiment 1

[0027] Medicament 2 in Example 1 of the present invention is 40 mesh amine perchloric acid eutectic salt SY, which is moistened with alcohol, doped with 3wt% of ultrafine aluminum powder, mixed uniformly by drum method, and then dried and stored for later use.

[0028] Add agent 2 into the hopper of the detonating cord making machine, the outer diameter of the control cord is within 6.0mm, and the filling density is greater than 1.0g / cm 3 , And then turn on the cable, the medicine 2 enters the polyester film 3 coil uniformly and continuously under the guide of the core wire 1. The polyester film 3 is first wound clockwise by the first polypropylene flat yarn 4, and then passed through the second polypropylene The flat wire 5 is wound counterclockwise to make the charge firm and compact to reach the set density; the formed detonating cord base material is finally coated with high-pressure polyethylene plastic 6 to obtain a detonating cord with a diameter of 5.4mm. The measured line ...

Embodiment 2

[0031] In Example 2 of the present invention, the agent 2 is 40 mesh amine perchloric acid eutectic salt SY, which is moistened with alcohol and doped with 2wt% 1000 mesh MoS 2 , Drum method to mix evenly, then dry and cool for use.

[0032] The drawing process and process are the same as in Example 1. The obtained detonating cord diameter is 5.4mm, and the measured linear density is 8.2 g / m, the detonation velocity is 4315m / s.

Abstract

The invention discloses a detonating cord based on SY detonating cord charge. The detonating cord is wrapped from the inside to the outside by core medicine, polyester film, polypropylene flat wire and polyethylene plastic layer by layer, wherein the core medicine is formed by wrapping the core wire with medicine, and the medicine is amine high Chloric acid eutectic salt SY. The core drug filled in the detonating cord is an energetic agent with an amine compound perchlorate as the main drug. Under the ignition action of the electric ignition head, detonator or delay element, it can quickly reach the detonation output, thereby replacing Engineering detonators for reliable detonation of civilian explosives.

Description

Technical field [0001] The invention belongs to the field of civilian blasting equipment, and relates to a detonating cord based on SY detonating cord charge, in particular to a detonating cord based on triethylenediamine·ethylenediamine perchloric acid eutectic salt charge. Background technique [0002] Civilian blasting equipment is an indispensable technical means in the field of engineering blasting. Its technical level and usage reflect the overall investment scale and economic development of the country. For my country, the annual use of engineering detonators has reached more than 2 billion rounds, ranking first in the world. How to reduce the consumption of materials, energy and manpower in the production process of detonators, simplify the manufacturing process, further reduce costs, and improve product market competitiveness will be a task of great practical significance. [0003] Since Nobel invented the detonator, the application of industrial explosives has entered a ...
