Problems solved by technology

[0005] (1) Only the detonation wave is transmitted, and the ignition effect cannot be performed on the rock;
[0006] (2) The explosive components loaded can only be detonated by shock waves;
[0007] (3) The gas products produced by the detonation will produce toxic gases at the site of use;
[0008] (4) The mechanical sensitivity of detonating powder is high, and the danger in production is great;
[0009] (5) The temperature of the plastic detonating tube is too high during processing, which may easily cause accidental combustion of the detonating charge, or even accidental explosion

Abstract

The invention relates to a thermobaric detonator, comprising a double-layer composite pipe, the double-layer composite pipe includes a first plastic layer located on the outer layer, a second plastic layer arranged close to the inner surface of the first plastic layer, and The accommodating space located inside the second plastic layer, the accommodating space is filled with thermobaric propellant; and the raw material components of thermobaric propellant are limited, so that the thermobaric detonator according to the present invention can use thermobaric thermal effect Mainly, it can only ignite at high temperature, does not produce detonation, detonation reaction, only deflagration and combustion, produces high impact and heat to participate in rock breaking work; the temperature and pressure detonator utilizes the exothermic reaction of condensed phase special energy Realize temperature-pressure ignition to finally realize harmonious blasting; the temperature-pressure detonating tube of the present invention can not only achieve the predetermined blasting effect, but also realize the fundamental control of the harmful effects of blasting, and finally realize fast, efficient, safe, reliable, green and economical Reasonable blasting operations.

Description

technical field [0001] The invention belongs to the technical field of blasting equipment, and in particular relates to a thermo-pressure nonel and a preparation method thereof. Background technique [0002] The concept of plastic nonel: According to the standards issued by our country, the plastic nonel is to detonate various industrial detonators by transmitting detonation waves at detonation speed. The concept proposed by foreign patents is "a conductor that transmits shock waves". The plastic detonating tube is a plastic tube with an outer diameter of ≧3mm and an inner diameter of ≦2mm. The inner surface of the tube is coated with a high-energy active material (gunpowder), and one end is connected to a detonator, and the other end is connected to a detonator. After the detonation, the high-energy particles propagate in the tube with the detonation wave (shock wave) front, and detonate the detonator at the other end. This process is called detonation transmission, and th...
