Description

Copper core lead for fireworks

Technical Field

The utility model relates to a copper core lead wire for fireworks, this technique belong to fireworks and crackers field.

Background

In the prior art, the safety lead is made by taking pyrotechnic composition as a medicine core and cotton thread as a wrapping object, and is woven into an outer weaving layer, a varnish coating is arranged outside the outer weaving layer, a film coating layer is coated outside the varnish coating, or a waterproof film pipe is sleeved outside a lead body, or the outer layer of the safety lead is a thin pipe formed by plasticized double-base gunpowder, so that the safety lead has the defects that: 1. the lead varnish coating is coated with a film coating layer or a waterproof film tube, when the lead is connected with the firework paper tube, lead paper and paint attached to the outside can be extruded, the strength of the lead is reduced, the reliability of the lead inserted into the paper tube is influenced, the lead has poor folding resistance, and the phenomena of wire scattering, medicine leakage, fire breaking and the like can occur after the lead is repeatedly folded; 2. adopt the lead wire that plasticized double-base powder constitutes the thin tube and constitutes, can extrude the graininess powder in the bad lead wire, influence the change of lead wire inner structure, compress tightly the compaction with the medicine in the lead wire, some original characteristic factors of lead wire have been changed, the effect that the lead wire was touched off has been influenced, especially to some timing lead wires, thereby the time that the inside graininess powder of pressure damage lead wire can change the lead wire burning loses regularly effect, directly influence the effect of touching off regularly, probably cause the incident, there is the potential safety hazard. 3. The varnish coating on the surface of the lead is easily dissolved by an organic solvent, so that the cotton thread wrapping gunpowder is loosened until the powder leaks, the phenomenon of fire cutoff occurs, and the safe setting off and storage and transportation are not facilitated.
