Problems solved by technology

[0003] Potassium perchlorate is used as the oxidizing agent in the existing formulations of fireworks and firecrackers. The cost is high, the decomposition temperature is high, and the oxygen evolution rate is low.
Although there are currently a few companies that use potassium perchlorate, potassium nitrate, ammonium nitrate, barium nitrate and other raw materials to mix composite oxidizers and lattice combination oxidizers, and some research and development institutions have prepared composite oxidizers with catalysts, etc. , storage stability, caking and other aspects still have certain defects

Embodiment 1

[0025] Make the potion according to the following ratio

[0026] Component A: a mixture composed of 10% potassium perchlorate and 90% barium nitrate by mass percentage; the compound accounting for 0.5% of the mixture and the fumed silica accounting for 0.5% of the mixture; the complex is tartaric acid or potassium sodium tartrate;

[0027] Component B: 90% by mass percentage of magnesium-aluminum alloy, 10% of sulfur;

[0028] Mix 50% of component A and 50% of component B evenly by mass ratio, pass through a 120-mesh sieve at least three times until the color of the mixture is uniform, make firecracker medicament, and reproduce firecracker samples.

[0029] The prepared firecracker samples were tested by the Fireworks and Firecrackers Testing Center of Hunan Entry-Exit Inspection and Quarantine Bureau according to SN / T0306.4-2006, GB10631-2013, United Nations standards, etc. The results of the tests are as follows:

[0030] The detonation rate reaches more than 95%;

Abstract

The invention discloses low-sulfur firecracker chemicals and a preparation method thereof. The low-sulfur firecracker chemicals includes an oxidizing agent and a combustible agent, the oxidizing agent is composed of potassium perchlorate and barium nitrate oxide components and fumed silica and tartaric acid and / or sodium potassium tartrate additive components; the combustible agent is composed of magnalium and sulphur. The low-sulfur firecracker chemicals is low in cost of raw materials, simple in preparation method, good in explosion loudness, fire connecting capability, combustion rate and storage stability and the like when the chemicals is used in firecrackers, low in environmental pollution, low in injury to human bodies and wide in application prospect.

Description

technical field [0001] The invention specifically relates to a low-sulfur firecracker agent and a preparation method thereof, belonging to the technical field of fireworks and firecracker preparation. Background technique [0002] Existing firework and firecracker medicament formula mainly comprises oxidizing agent and combustible agent. Combustible agents generally include aluminum silver powder, magnesium aluminum alloy powder, charcoal powder, titanium powder and sulfur, etc. Among them, aluminum silver powder and sulfur are necessary raw materials, and the sulfur content is as high as about 20%. In addition, in order to reduce the charge, 10% perlite is often added. In the production process, because the particle size of aluminum silver powder is very small, it is easy to float into the air to form dust, which adheres to the body, hands, work surface and other places, causing environmental pollution and occupational injury. The presence of sulfur and perlite will produ...
