Embodiment 1

[0009] Embodiment 1, according to the timing effect of the golden light fireworks shell, the fuse gunpowder formula mass ratio is taken: 5.0-5.5 kilograms of potassium perchlorate, 1.0-1.5 kilograms of larch charcoal powder, 1.2-1.8 kilograms of potassium hydrogen terephthalate, yellow light 0.4-0.7 kg of agent, 1.0-1.5 kg of barium nitrate, 6.0-8.0 kg of quick-drying adhesive;

Embodiment 2

[0010] Embodiment 2, according to the timing effect of the silver light fireworks shell, the mass ratio of the fuse gunpowder formula is taken: 5.5-6.0 kg of potassium perchlorate, 0.4-0.6 kg of carbon powder, 1.2-1.5 kg of potassium hydrogen terephthalate, and 2.5-6 kg of titanium sponge. 3.0 kg, 0.8-1.2 kg of barium nitrate, 6.0-8.0 kg of quick-drying adhesive.

[0011] Among the components of the above examples, the quick-drying adhesive is selected according to the mass ratio: 0.8-1.2 kg of moisture-proof agent, 1.8-2.3 kg of acetone, 0.05-0.1 kg of rosin, 0.8-1.2 kg of nitrocellulose, and 6.5-7.0 kg of alcohol Made by mixing.

[0012] The production process of gunpowder is as follows: fully mix potassium perchlorate, larch charcoal powder, potassium hydrogen terephthalate, yellow light agent, and barium nitrate according to the above-mentioned golden light fireworks bomb timing effect fuse gunpowder formula, or mix potassium perchlorate, carbon powder , Potassium hydroge...

Abstract

The invention relates to a formula of gunpowder for a timing firing cable of a display shell. According to the invention, because in the formula provided by the invention, potassium perchlorate is used as a main component, thereby completely avoiding the use of a high-risk potassium nitrate product and effectively reducing the generation of risk accidents caused by a firing cable; barium nitrate in the components has combustion and speed regulation effects, so that the combustion speed of the firing cable meets the timing ignition requirement of the display shell, thereby effectively achieving the timing effect; and the combustion color of the firing cable is golden or silvery through using larch carbon powder, a yellow light agent or titanium sponge in the components.

Description

technical field [0001] The invention relates to a powder formula for a firework bomb timing effect fuse. Background technique [0002] The gunpowder used in the traditional production of fireworks bomb fuses is composed of potassium nitrate as the main ingredient. Potassium nitrate is a high-risk product, and it will cause combustion and explosion when it is heated by impact. At the same time, potassium nitrate is easy to be affected by moisture. If it is damp, the fuse will not burn and become invalid. . With the country's emphasis on safety work and the need to ensure the safety of people's lives and property, it is urgent to use other chemical products with a high safety factor to replace potassium nitrate. Simultaneously, the timing effect fuse of the fireworks bomb also needs to meet the requirements of timing ignition. Therefore, it is an urgent need for the fireworks industry to develop a new type of fireworks bomb timing effect fuse propellant formula that has a hig...
