Problems solved by technology

[0003] Traditional firecrackers often use sulfur in their drug formulations, which produce sulfur dioxide and sulfur trioxide after burning, causing damage to the human body and the atmosphere
And in the prior art, firecracker medicament produces smog more when setting off, causes very big pollution to urban air near setting off site
Some existing firecrackers have poor safety and stability

Embodiment 1

[0014] The raw materials are passed through a 200-mesh sieve, and 30 parts of bamboo charcoal powder, 20 parts of potassium perchlorate, 15 parts of nano-silver powder, 10 parts of nano-rare earth oxide, 4 parts of carbon powder, 4 parts of titanium sponge powder and 3 parts of agarwood powder are taken by weight. After spraying water accounting for 8% of the total weight of the medicament, mix evenly, charge and insert to make firecrackers.

Embodiment 2

[0016] Pass the raw materials through a 200-mesh sieve, and take 30 parts by weight of bamboo charcoal powder, 10 parts of potassium perchlorate, 10 parts of nano-silver powder, 15 parts of nano-rare earth oxide, 2 parts of carbon powder, 2 parts of titanium sponge powder, and 4 parts of agarwood powder. After spraying water accounting for 8% of the total weight of the medicament, mix evenly, charge and insert to make firecrackers.

Embodiment 3

[0018] The raw materials are passed through a 200-mesh sieve, and 30 parts of bamboo charcoal powder, 30 parts of potassium perchlorate, 20 parts of nano-silver powder, 5 parts of nano-rare earth oxide, 6 parts of carbon powder, 5 parts of titanium sponge powder and 1 part of agarwood powder are taken by weight. After spraying water accounting for 8% of the total weight of the medicament, mix evenly, charge and insert to make firecrackers.

[0019] Detected by the National Fireworks and Firecrackers Product Quality Supervision and Inspection Center, the light smoke and sulfur-free firecrackers prepared by the above-mentioned embodiments have a friction sensitivity of 0, an impact sensitivity of 0, and a moisture absorption rate≤1.12% (the friction sensitivity test method is in accordance with SN0545-1996). 5.5; impact sensitivity test method according to 5.4 in SN0545-1996; hygroscopicity according to QB / T1914.5 method). According to the standard of GB10631-2004 "Safety and Qu...

Abstract

The invention relates to a micro-smoke sulfur-free agent for a firecracker. The micro-smoke sulfur-free agent for the firecracker is prepared from the following components in parts by weight: 30 parts of bamboo charcoal powder, 10-30 parts of potassium perchlorate, 10-20 parts of nanosiliver powder, 5-15 parts of nano rare earth oxides, 2-6 parts of charcoal powder, 2-5 parts of titanium sponge powder and 1-4 parts of agilawood powder. The firecracker using the agent provided by the invention is micro-smoke, sulfur-free and environment-friendly during combustion. The firecracker has fragrance of bamboo and agilawood during combustion, and the friction sensitivity, the impact sensitivity and the moisture absorption are superior to the state standards.

Description

[0001] technical field [0002] The invention relates to a pyrotechnic composition, in particular to a light-smoke and sulfur-free firecracker composition. Background technique [0003] Traditional firecrackers often use sulfur in their medicinal formulas, which produce sulfur dioxide and sulfur trioxide after burning, causing damage to the human body and the atmosphere. And in the prior art, firecracker medicament produces smog more when setting off, causes very big pollution to urban air near the setting off site. Some existing firecrackers are relatively poor in safety and stability. Therefore, people expect a kind of more environmental protection and safer firecracker. Contents of the invention [0004] The purpose of the present invention is to provide a kind of firecracker agent that only has micro smoke after explosion and no sulfur dioxide is produced. [0005] The micro-smoke and sulfur-free firecracker medicament provided by the invention comprises the fol...
