Problems solved by technology

[0009] The explosives of the fireworks and firecrackers disclosed in the above invention patents do not contain metal powder, and the invention patent CN103396276A uses potassium hydrogen terephthalate instead of aluminum powder as a reducing agent. Since it does not contain metal powder, although it solves the short shelf life of the explosives, The problem of poor safety performance, but the explosive force of firecrackers and the ignition rate of bright beads have been reduced, and there is no crackling effect produced by metal burning

Abstract

The invention discloses a fireworks and crackers blasting-agent composition. Agents in the fireworks and crackers blasting-agent composition include, by weight, 40%-60% of potassium perchlorate, 15%-30% of potassium acid phthalate, 10%-20% of a metal-filled multi-walled carbon nanotube, 5%-10% of metal oxide and 3%-5% of black powder, the multi-walled carbon nanotube is filled with one or more combinations of metals of aluminum, silver, iron, nickel, potassium, magnesium, lithium, sodium and the like, and the metal oxide is one or more combinations of ferroferric oxide, iron sesquioxide, copper oxide, manganese oxide, zinc oxide, cobalt oxide and aluminum oxide. The fireworks and crackers blasting composition agents free from metal powder are obviously improved in security coefficient, the explosion dynamics of the agents is high, burning rate of bright points is high, shelf life is long and blasting effect is good.

Description

technical field [0001] The invention relates to a combination agent for opening firework and firecrackers, in particular to an agent composition for opening explosion of fireworks and firecrackers without metal powder. Background technique [0002] Fireworks and firecrackers generally consist of lead wires, paper tubes and explosives. The existing explosives for fireworks and firecrackers use potassium perchlorate as an oxidizing agent, metal powders such as aluminum powder and magnesium powder as a reducing agent, and add a small amount of sulfur to increase the brightness of the beads. Rate. Due to the strong hygroscopicity of the metal powder, it is easy to deliquify the detonating agent, and the produced detonating agent has a short shelf life, large quality differences, weak launch force, and relatively large lateral force. And the breaking agent containing metal powder has high sensitivity and low safety factor. Therefore, foreign countries have made limited require...
