Embodiment 1

[0017] Dissolve the celluloid with a mixed solvent of acetone and alcohol (the mass ratio of acetone, alcohol and celluloid is 1:3:1) to make a celluloid solution. Spray evenly on 30 parts of ammonium perchlorate with 2.5 parts of celluloid solution in parts by weight and mix well.

[0018] Mix carbon powder and nitric acid (69.2% by mass) at a mass ratio of 7:3 at room temperature and stir for 10 minutes, filter out the acid and air-dry.

[0019] Take 50 parts by weight of single-base powder, 20 parts of rare earth, the ammonium perchlorate prepared above, and 15 parts of charcoal powder prepared above, mix evenly, and pass through a 160-mesh sieve to prepare the lead agent. According to the conventional method of making the fuse, the fuse agent is wrapped and twisted into a thread with the fuse paper, and the consumption of the fuse agent is 3 grams / 1 meter of the fuse paper, and then pulped and dried to obtain the fuse. The burning speed of the fuse: 0.80m / s; the moisture ...

Embodiment 2

[0021] Dissolve the celluloid with a mixed solvent of acetone and alcohol (the mass ratio of acetone, alcohol and celluloid is 1:2:0.8) to make a celluloid solution. Spray evenly on 20 parts of ammonium perchlorate with 1.5 parts of celluloid solution in parts by weight and mix well.

[0022] Mix carbon powder and nitric acid (69.2% by mass) at a mass ratio of 7.5:3 at room temperature and stir for 20 minutes, filter out the acid and air-dry.

[0023] Take 40 parts of single-base powder in parts by weight, 10 parts of rare earth, the ammonium perchlorate prepared above, and 20 parts of carbon powder prepared above are mixed, and passed through a 160-mesh sieve to prepare the lead agent. Combed cotton yarn is used to wrap the fuse agent and twist it into a thread shape. The dosage of the fuse agent is 3 grams per 1 meter of cotton yarn, and then sizing and drying are carried out to obtain the fuse. The burning speed of the fuse: 0.78m / s; the moisture absorption rate is 0.80%. ...

Embodiment 3

[0025] Dissolve the celluloid with a mixed solvent of acetone and alcohol (the mass ratio of acetone, alcohol and celluloid is 1:4:1.2) to make a celluloid solution. Spray evenly on 40 parts of ammonium perchlorate with 3.5 parts of celluloid solution in parts by weight and mix well.

[0026] Mix carbon powder and nitric acid (69.2% by mass) at a mass ratio of 6.5:3 at room temperature and stir for 10 minutes, filter out the acid and air-dry.

[0027] Take 65 parts by weight of single-base powder, 30 parts of rare earth, the ammonium perchlorate prepared above, and 10 parts of charcoal powder prepared above, mix them evenly, and pass through a 160-mesh sieve to prepare the lead agent. Wrap the wire-leading agent with wire-leading paper and twist it into a thread shape. The dosage of the wire-leading agent is 3 grams per meter of wire-leading paper, and then paste and dry to obtain a fuse. The burning speed of the fuse: 0.81m / s; the moisture absorption rate is 0.77%.

Abstract

The invention relates to smokeless firework lead powder and a firing line thereof. The smokeless firework lead powder comprises the following compositions in parts by weight: (A) 40-65 parts of monomer powder, (B) ammonium perchlorate, (C) 10-20 parts of carbon powder and (D) 10-30 parts of rare earth, wherein the ammonium perchlorate is obtained by adopting the following methods: evenly spraying celluloid nitrate dissolution liquor onto 20-40 parts of ammonium perchlorate and evenly mixing, wherein the celluloid nitrate dissolution liquor is obtained by dissolving celluloid nitrate through an acetone and alcohol mixing solvent; the carbon powder is obtained by adopting the methods: mixing carbon powder and nitric acid, filtering off acid liquor and drying. In burning, the smokeless firework lead powder is smokeless and has no sulfur flavor, the ornamental effect of fireworks can be improved, no sulfur dioxide is generated, the dampness-proof effect of a lead is good, and the safety performance is good.

Description

[0001] technical field [0002] The invention relates to a firework pyrotechnic agent composition, in particular to a fireworks micro-smoke lead agent. Background technique [0003] In the prior art, fireworks fuses are mostly made of smoked medicines. When using these leads, the effect of smokeless fireworks will be greatly affected. A large amount of smog and sulfur dioxide will cause great pollution to the air. Contents of the invention [0004] The purpose of the present invention is to provide a kind of fuse medicine and its fuse which only has micro smoke after burning. [0005] The firework micro-smoke lead agent provided by the invention comprises the following components in parts by weight: [0006] (A) 40~65 parts of single base powder; [0007] (B) Ammonium perchlorate obtained by the following method: Spray evenly on 20 to 40 parts of ammonium perchlorate with celluloid solution and mix well. get dissolved; [0008] (C) 10-20 parts of charcoal powder obta...
