Problems solved by technology

[0002]In the current actual production, the firework propellant has been using black powder (military nitrate) composed of potassium nitrate, charcoal and sulfur, which will produce A large amount of smoke affects the effect of setting off fireworks, and a large amount of oxides and residues of carbon, sulfur, and potassium remain in the air, seriously polluting the environment
The Chinese invention patent with the publication number CN101215211A discloses a "smokeless fireworks agent", which is composed of nickel hydrazine nitrate and perlite powder and other auxiliary materials, but nickel hydrazine nitrate is a complex priming agent, and improper use may easily cause safety accidents , the safety performance is not guaranteed, and the production cost is high (about 50,000 yuan per ton), so it is difficult to apply
Or adopt ammonium perchlorate or similar as a kind of oxidizing agent or oxidizing agent, but its moisture absorption rate is higher, and ammonium perchlorate has deliquescence, has limited the application promotion of this type of product

Embodiment 1

[0008] Embodiment 1: A sulfur-free fireworks propellant, the parts by weight of each component are 60 parts of potassium perchlorate, 15 parts of charcoal, 17 parts of potassium hydrogen phthalate, and 8 parts of resin.

[0009] Weigh 6kg of potassium perchlorate, 1.5kg of charcoal powder, 1.7kg of potassium phthalate, and 0.8kg of resin, mix the components evenly by hand or mechanically, then mix the medicine evenly with an appropriate amount of alcohol, and then use a 16-mesh sieve Extrude the granules, put them into the bright bead machine to roll out the granules of qualified size (1.0-2.0mm), dry or dry them to get the finished sulfur-free propellant.

Embodiment 2

[0010] Embodiment 2: A sulfur-free fireworks propellant, the parts by weight of each component are 70 parts of potassium perchlorate, 10 parts of charcoal, 12 parts of potassium hydrogen phthalate, and 8 parts of resin.

[0011] Weigh 7kg of potassium perchlorate, 1.0kg of charcoal powder, 1.2kg of potassium phthalate, and 0.8kg of resin, and mix the components evenly by hand or mechanically, then mix the medicine with an appropriate amount of alcohol, and then use a 16-mesh sieve Extrude the granules, put them into the bright bead machine to roll out the granules of qualified size (1.0-2.0mm), dry or dry them to get the finished sulfur-free propellant.

Embodiment 3

[0012] Embodiment 3: A sulfur-free fireworks propellant, the parts by weight of each component are 74 parts of potassium perchlorate, 10 parts of charcoal, 10 parts of potassium hydrogen phthalate, and 6 parts of resin.

[0013] Weigh 7.4kg of potassium perchlorate, 1.0kg of charcoal powder, 1.0kg of potassium phthalate, and 0.6kg of resin, mix the components evenly by hand or mechanically, then mix the drug evenly with an appropriate amount of alcohol, and then use a 16-mesh Extrude the granules through a sieve, put them into a bright bead machine to roll out the qualified sized granules (1.0-2.0mm), and dry them in the sun to get the finished sulfur-free propellant.

[0014] Get the finished product of sulfur-free propellant in each embodiment and carry out safety performance test, the results are shown in the following table 1:

Abstract

The invention relates to a pyrotechnic composition, and especially relates to a sulfur-free firework propellant. The sulfur-free firework propellant is composed of 60-75 parts of potassium perchlorate, 10-20 parts of charcoal, 10-20 parts of potassium biphthalate and 5-10 parts of resin. Compared with the prior art, the sulfur-free firework propellant has the following advantages that 1)while combusting, the combustion products is potassium chloride, carbon dioxide and water, nitrogen, sulfur and harmful forbidden drugs are not contained, atmosphere pollution is greatly reduced, and environmental protection performance is provided; 2)safety performance can satisfy the national standard requirement; 3)moisture resistance is good, the medicament is stable, long-term (in five years) storage performance is normal; and 4) economy is good, and the popularization and application are easy.

Description

technical field [0001] The invention relates to a pyrotechnic powder, in particular to a sulfur-free fireworks propellant. Background technique [0002] At present, in actual production, firework propellants have been using black powder (military nitrate) composed of potassium nitrate, charcoal and sulfur, which will produce a lot of smoke when burning, which will affect the effect of fireworks and leave a large amount of gunpowder in the air. The oxides and residues of carbon, sulfur, and potassium in the atmosphere seriously pollute the environment. The Chinese invention patent with the publication number CN101215211A discloses a "smokeless fireworks agent", which is composed of nickel hydrazine nitrate and perlite powder and other auxiliary materials, but nickel hydrazine nitrate is a complex primer, and improper use may easily cause safety accidents , the safety performance is not guaranteed, and the production cost is relatively high (about 50,000 yuan per ton), so it ...
